From the time I was in my mid teens, I always imagined I would get married and have a lot of kids. I wanted to get married young and have as many kids as my wife and I could afford; I just felt like being a dad was ‘in my blood’. When I was 19, I met a beautiful girl named Jessica and we were fast friends. We fell in love and got married within just a few months of meeting—she was still 18. Barely a month after we were married, Jess was pregnant and we were on the path to having the large family we talked about and wanted.

Jessica was a social butterfly and always made friends easy. I really enjoyed watching her glow in the attention her friends gave her. Her girl friends tried to be like her and her guy friends wanted to be with her. Jessica’s best friend, Lisa, had been pressuring her and me to try swinging. I wasn’t big on the idea, but Jessica was curious about it. Lisa said we should just attend a party—no pressure to participate—and if we didn’t like it, then that was fine. She said condoms were required to keep everyone safe and to avoid any pregnancies by unintended fathers. I agreed with that rule… I could tell Jess wanted to go, so I said we could go if she wanted to. We went to the party and she was really into it. And to be honest, I was getting more curious, too. Swinging wasn’t about love with another person; it was just about different sex experiences. Jess and I talked at length about trying it and we decided to ‘test the waters’. The next time Lisa hosted a party, we attended and to my surprise, we both had a really good time. After the party, we went home and had sex (sans condoms this time) and it was the best sex we had ever had.

After Lisa’s swinger’s party, we didn’t really feel the need to go again. Our sex life (which was really good before) had become incredible afterwards. Several months passed and Jessica became pregnant. We were thrilled to be starting the family we had been talking about! The bonus for me was that being pregnant made Jess unusually horny. But the further along she got, the more trouble I had keeping up with her. When she was six months along, I didn’t have enough to satisfy her and, after some discussion, we decided to try swinging with Lisa and her group again. Lisa was surprised since it had been nearly 9 months since we tried it, but was happy to hear from us again. Lisa put together a last-minute party for us and Jessica was thrilled. I had sex with three of the women there; she must have had sex with every guy there! They still used condoms per the rules: she couldn’t be more pregnant, but there are still the threats of diseases… I was really getting into the swinging scene, too: it was great to learn new things from other women and watching Jess have sex with some guy while looking and smiling at me was pretty hot…

We began swinging at least once a week for the next three months just to fulfill Jess’s needs. I was fine with it because I knew it was just sex and that she loved me as much as I loved her. Jessica gave birth to our daughter, Erin, and things went back to normal. There was NO sex for the first six weeks after the baby was born, of course. But once she was able again, we picked back up where we ‘left off’.

When Erin was about to turn a year old, I asked Jessica when she thought she might be ready to have another baby. She said she wasn’t sure yet and I was ok with that—being pregnant was not easy for her. Everything else was perfect so I really had nothing to complain about—at least I thought it was perfect. But one day I came home to a note on the door that said Erin was with the baby sitter and that Jess was leaving. She barely took anything with her and said she didn’t want anything: the family life was too much pressure on her and she felt that she was not cut out to be a mother. I was naturally devastated. Not long after that, divorce papers came in the mail: she filed for an uncontested divorce, forfeited her rights to any/all property and even gave up her parental rights to Erin. I knew then that it was unlikely I’d ever see Jessica again. That hurt, but I had my daughter to take care of now and I put everything into raising her while putting all of my dreams away.

Weeks turned into months and months into years. Erin was growing fast and it was easy to see both me and her mother in her. She definitely had my cheeks, chin, and ears, but she had her mom’s lips, nose and eyes. Erin was a beautiful young girl and everyone, even strangers, said so.

When Erin was 10, I received a job offer that I couldn’t pass up and we relocated to accommodate my new position. The thought was that when Erin graduated high school, she could attend the university nearby and could stay home instead of living in a dorm room or having to rent an apartment. But that was years away at that time. In the meantime, I excelled in my new job and was saving as much as I could to afford Erin’s college fund. I had no time for dating and wasted little money on myself. My life was for Erin. When my daughter was in her junior year of high school, she tried to ‘hook me up’ with a various few of her friend’s single moms, but I really wasn’t interested at the time. I told her I would tend to my personal life after I was done raising her: she was my number one priority for now.

Erin applied to the local university and was accepted with a full scholarship; I was so proud of her! At the same time, it broke my heart to see her “going away to college” (she was still living at home, though). My daughter and I were incredibly close and I knew that it wouldn’t be long before she was going out into the world—completely on her own—and my life wouldn’t be the same. I found myself wishing I had a house full of more kids to raise and felt cheated out of that by Jessica. I took some comfort in the fact that I had one amazing daughter, but I was a bit selfish and wanted more. I decided I had to get my mind on other things and remembered my promise to Erin: that I would start dating again after she went to college. When she was in her first semester, I entered ‘the dating pool’. It didn’t go too well, but I kept at it. I did some searching on line for things like dating services and even dating ‘events’. I attended several with limited success. Then one day, I found a blog that mentioned an upcoming swinger’s event. This particular event did not require you to show up with a partner—which was rare. Swinging was something I had thought about a lot over the past 18 years, but never had the time—never took the time—to get back into. I looked into the party and found out it was going to be a Halloween party; everyone would be wearing costumes for the duration and I thought that was perfect!

For reasons I can’t explain, I kept thinking about all of the kids I wanted to father. It was like a kind of fantasy of mine to know that there were a bunch of kids running around out there with my DNA. It was this absent-minded thinking that hatched an idea in my head. I came up with a plan to try and make that happen. I bought a case of condoms and a fine cutting tools kit. After practicing a few times, I was able to carefully cut open a condom, put several holes in the tip, and reseal the package—making it look like it had never been opened. I knew this was very wrong of me, but I couldn’t stop myself! I ‘altered’ about six condoms and saved them for the Halloween party.

It was mid October and I picked out my costume—I would be going as Spiderman. I figured it was perfect because I still had the body to pull it off and the mask completely hid my face. The day before the party, Erin asked me if I’d be handing out candy for the trick-or-treaters and I told her I was going out. She said she had a lot of studying to do and was going to a friend’s house to study together. I told her she should go out and enjoy the night for once, but she said there was a big test coming up and couldn’t afford to slack off; there was always next week…

It was Halloween night and I had my Spiderman costume on under my normal clothes to make changing easier. In anticipation of the party, I made one alteration to my costume: I cut a slot in the crotch and sewed some Velcro into it for ‘easy access’ once the action got started. The ‘special’ condoms were just tucked into the waist band. I got in my car and headed out to the party. When I got to the address, I was surprised at how many cars were there—I had to park down the street; it was going to be a big event! I put on my mask and took off my regular clothes and my transformation was complete.

I walked inside the house and there were people everywhere! Some were mingling and others were already ‘getting busy’. I was looking around the room, looking for a girl that wasn’t taken—there were many to choose from. But it was a small group of 4 girls that caught my eye. They were standing in a corner and just watching the action. A lot of guys were also looking at them, but they seemed too intimidated to approach them. I figured I’d been around too long to worry about rejection, so I walked right over to the girls. They were all wearing skin-tight costumes that showed off every curve and their bodies were unbelievable! I wanted to rip their masks off to see if their faces were as beautiful, but that wouldn’t be ‘appropriate’. This party was clearly about anonymous sex: not one person had any part of their face visible here—including the girls. I decided to keep it completely anonymous by not talking to the girls and letting my actions speak for themselves.

Two of the girls were admiring my muscles under my costume and the other two just rubbed them tentatively in agreement. My dick was starting to grow and one girl took notice right away. She was dressed like a sexy black cat; costume complete with a tail and ‘fuck me high heels’. She grabbed my crotch and lightly lifted me up—getting a good feel of my now hard cock. Noticing that I wasn’t saying anything, she played the same game and kept silent, too. She took my hand and placed it on her magnificent tit. I began to caress her breast from over the thin stretchy fabric covering it. She began stroking my cock hiding under the skin tight blue pants and I opened the Velcro fly to let my dick out. Once it was free, she had it in her hand and was stroking it slowly up and down. Honestly, it wasn’t the best hand job I’d ever had, but from the shape of her body, she was more than likely still pretty young and probably didn’t have much experience. But a hand job is a hand job: I wasn’t complaining.

She pulled her top up to over her tits and they were stunning! I played with her nipples and the girl was beginning to really warm up to me. The ‘cat woman’ turned around and pushed her butt into my dick, pinning it between us. I had my right arm around her waist and on her left hip while my left was around her chest; my hand on her right breast. She had both hands up over her head and reached back to hold my head in her hands as she slowly and sensually moved to my caressing. I slipped my right hand down into her pants and was not surprised to find she was not wearing panties. I could also tell that she was clean shaven—waxed more likely; she didn’t even have any stubble. Her pubic area was completely smooth and soft. My fingers quickly found the top of her slit and her clitoris hiding inside. She was humping my finger as it danced across her sweet spot and she finally whispered, “Do you have a condom?” I produced one of my ‘special condoms’ and she led me over to an open spot on the couch.

She took the spot on the couch, but didn’t sit on the couch; she was on her knees and leaning over the back of it. She was looking over her shoulder and I knew she was waiting for me to ‘suit up’. I opened the condom and put it on myself. I knew it was a bit risky since I didn’t know if she was carrying any STS’s, but I figured she seemed pretty young still and it was unlikely that she had anything. And the thought of this stranger trying to figure out how she ended up pregnant and who the father might be was too much of a thrill to pass up! As soon as she saw the condom going on, she turned back around and pushed her butt out to me. I got behind her and grabbed her stretchy pants by the sides and slowly pulled them down her perfect ass, exposing it inch by inch. The first thing I noticed was she at a fairly new ‘tramp stamp’ right at the top of her crack. I was never big on tattoos, but this one was actually pretty nice on her. I studied it closely, remembering the curving lines and how they perfectly complimented her ass cheeks. I pulled her pants down and off of her, but left her heels on her. Then I put my hand under her crotch and I could feel a tremendous amount of heat radiating from her hairless tight pussy. I slid my finger up and down her slit and found her clit again. I played with it for a while and she was becoming very slick. I sat her down on the couch and had her spread her legs wide. I just had to taste her pussy or I would surely die. Once my face was in position, I closed her legs until they were touching my ears and cheeks. Then I pushed up the bottom of my mask to expose my mouth. No one could see any part of my face—not even the cat girl. My tongue quickly found her clit and I went to work on it. Her hand went immediately to the back of my head and she pulled my face into her dampening crotch with force. I sucked and licked every square millimeter of her pussy like my life depended on it—not one part of her pink bits escaped my mouth.

Eating a girl’s box that was this devoid of hair or stubble was a special treat—rare—and I was savoring it! I spread her pussy lips far apart and her clit stood out naked to the world; I had a good close up view of it. I memorized the look of her ‘little man’ and I knew I’d be able to pick it out of a lineup of a thousand others even years from now. I sucked the little clit into my mouth and gave her a mini blowjob. She was hissing and gasping in lust to my oral onslaught on her. I was eating this pussy’s pussy like there was no tomorrow and she loved it! I didn’t want her to orgasm yet, though, so I stood up and had her get back on her knees while leaning over the back of the couch.

I stood behind her and started rubbing my dick on her pussy to use some of her juices to lube up my condom encased dick. I placed my cock head at the opening to her pussy and I pushed forward. This cat girl was really tight! But I was shocked when my dick met her hymen and ripped it open—she had been a virgin until now! Her moan at losing her virginity was lost amongst all of the other moans and miscellaneous sounds of sex in the filled room. I had the cat girl by the hips and I began rocking into her. I couldn’t believe she had given her virginity in such a way and I was going to try and knock her up during her first sexual experience! She quickly got used to the feeling of my invading member and began pushing back into me. I was pumping into her at a slow and steady pace, all while looking at her tramp stamp tattoo and the small amount of blood on my dick. I let her set the pace for our fucking—it was the ‘gentleman’ thing to do…

Pretty soon, our pace was picking up and eventually it built until I was slamming in and out of her pussy. I could tell she was really wet; even with the condom on. Her juices were coating the condom now and even washing away her virgin blood. The couple next to us finished and got up. The cat girl took their spot, too; lying down on her back with legs spread in the air. I repositioned over her and, as I reentered her, she wrapped her legs around me. She was naked from the waist down with the exception of her black stiletto heels and her top was still pushed up over her tits. I wanted to see her face, but that would have been wrong. I caressed her tits as I went back to thrusting into this first timer.

The condom helped me from having an orgasm too soon and she was having a great time! She was panting and trying not to moan too loud, but I was making that difficult for her. The more she tried to hold it back, the harder I fucked her. And the harder I fucked her, the harder it was for her to hold it back. Her responses to my actions were having an effect on me and my orgasm was building. But she beat me to it: her orgasm hit her and her already tight pussy clamped down on me even tighter. She screamed as her vaginal fluids released and dripped out of her. Several people from around the room applauded us. My orgasm hit and I could feel the tip of the condom fill with millions of sperm cells.

I kept pushing into the girl to try and get as many of them as possible through the holes I had poked in the tip. Since her pussy was already dripping wet, she couldn’t tell that the condom was being milked empty. I was pretty sure I had as much of my sperm pushed out as possible, but I was just enjoying sex with this girl. Her body was amazing. About 15 minutes after our orgasms, her friend (who was dressed up like her—only she was a grey mouse) came over and whispered in her ear. The cat girl nodded and moved to get up. I pulled my dick out of her and she got dressed. Her mouse friend did the opposite. Clearly, it was ‘her turn with Spider Man’.

I pulled off the now well used condom and saw the end of it had been shredded to ribbons. I disposed of it quickly before anyone saw it. I showed ‘mouse girl’ the new condom and she smiled. I put the special condom on and went to work on her. She was not as tight as the cat girl and she was definitely not a virgin. She was pretty well experienced, in fact. Strangely enough, even though she was technically better, the excitement level of the cat girl made the sex more enjoyable. But, no matter: I was going to work on jamming some cum up in this girl’s guts, too!

The mouse girl had me sit on the couch and she rode me in reverse cowgirl fashion. She began jumping on me like I was an adult-themed pogo stick. Every now and then, she would stop bouncing to rock and grind her hips on me. And when she did, she could control her vaginal walls to massage my dick. That was a new feeling for me—one that I could feel even through the condom! She would do that for a while and then go back to jumping on my cock. During one of her jumping sessions, I felt the condom bust open and get pushed down my cock, all in one jump. She didn’t seem to notice and if she did, she didn’t care. But there was no doubt in my mind that my condom was now nothing more than a ring of bunched up latex around the base of my dick.

The mouse girl stopped bouncing and began rocking, grinding, and massaging my dick with her pussy walls. She still didn’t realize my cock was naked inside of her now unprotected pussy. My orgasm built quickly and I blew a decent sized load right into and past her cervix. Her eyes shot open in realization and her own body had an orgasm in automatic response. She turned her head to the side and asked to verify that I was wearing a condom. I shook my head ‘yes’ and she seemed doubtful of herself. She reached between her legs and found the condom in place, but didn’t notice it was torn to shreds. Satisfied it was there, she went back to fucking me. When she was finished, she simply stood up and walked away without even turning around to look at me. That sounds rude, but it was actually pretty hot; I didn’t mind being used by a hot young girl!

Before I could get up, the cat girl came back over and stood before me. She made a square shape with her index fingers and thumbs while tilting her head to the side. The question was clear: “Do you have another condom?” I produced another and she pointed to my still hard dick. I put it on and she turned around while pulling her pants down. She had been watching her friend and me going at it and wanted to try what the mouse was doing. She straddled over my legs and sat down on my cock. Even after having fucked a short time ago, she was still very tight. I held her by her slim hips and she tried jumping on my cock. But she was so tight I could tell the condom wasn’t going to last long. After just a few small bounces, I could feel my cock head poking out of the tip. I was too busy looking at her tattoo to even care. I knew that as long as I lived, I would never forget that tattoo.

She was leaning forward, supporting her upper body on her hands which were on my knees. Every time she rocked her hips back and down, I could see my dick disappearing inside her. And I knew that even though the part of my dick that I could see looked securely wrapped, the top was completely open to her pussy. The cat girl started to lean back and I took the opportunity to slide my hands under her top and hold her perfectly shaped tits again. I could feel my cockhead pushing into her cervix with force and she was moaning again. My orgasm was building and hers was too. Once again, hers hit a second before mine and we blasted our fluids all over and in each other.

After our orgasms subsided, she kept herself impaled on my cock for about five minutes before standing up. She didn’t just walk away as her mouse friend had done, though. She turned around and blew me a kiss from her kitty mouth and waved ‘good bye’. I waved back and her mouse friend joined her as they went out the front door. I was pretty well spent having had three orgasms, so I left right behind them. I saw them get in their car—the mouse girl was driving. She took off her mask but I couldn’t see her face in the darkness. They drove away and I knew I’d never see them again. I walked to my car which was down the street and was a little disappointed that I wouldn’t see them again, but then again, that was the point of having anonymous sex! When I got to my car, I put my regular clothes back on and removed my mask. For a moment I felt like a superhero—or perhaps super villain (pretty evil to try and knock up a couple of unsuspecting girls…).

I went home and showered while reliving the evening in my head. Just thinking about the cat girl was enough to get my dick hard. But I had to put her out of my mind or else walk the rest of my life with a raging boner. I threw the costume in the garbage and started doing more searching for singles and swingers in the area. Over the next few weeks, I attended a few swingers groups, but there was nothing like that Halloween party. For sure the cat and mouse girls were not there—the swingers I was seeing were definitely older than most of those at the Halloween party.

It was a Friday night and I was just getting home after having been at a singles meeting. There wasn’t anyone there that really interested me so I was calling it a night. When I pulled into my driveway, I saw Erin was home from college. She had been staying with her friend during the weeks to help cut down on commuting to and from school (traffic could be bad in the mornings). I parked the car and went inside. Erin greeted me and I asked her how she was doing in school. She was already showered and in her pajamas. We were talking at the kitchen table and I got up to get her a snack before bed; she got up to help. We continued to talk as we prepared our snacks; after living with each other for the last 18 years, we worked well together. But I was a bit distracted by some of my thoughts and, as I was handing her a fork, I let go of it before I knew she had a handle on it. The fork fell to the floor with multiple ‘clings’ and she bent down to pick it up. I turned to look at what I had done and saw her picking up the utensil from the floor. That was when I saw that her pajama bottoms had slipped down a little and she had a tattoo.

I only saw the very top of it, but I knew it was there. I called her out on it immediately. I asked, “Is that a tattoo?!” She shot upright and knew she was busted. She admitted to having it and I told her, “Let’s see it…” She turned around and pulled down the top-back of her pajama bottoms. To my shock and horror, I recognized the tattoo immediately: without question, Erin was the cat girl.

I felt like I might pass out. In a flood of realization, I knew that I had fucked my own daughter, taking her virginity, and that I had at least attempted to plant my seed in her fertile womb. I had to sit down. She saw my reaction and presumed it was just because of the tattoo. She said, “Daddy, are you ok? Please don’t be mad: it’s just a tattoo and I really like it.” I said, “No, I’m not mad about the tattoo. I’m not mad at you at all.” She asked, “Then what’s wrong?” I realized she had no idea that I was ‘Spiderman’ and I thought it would definitely be better to not tell her. But I had to come up with a reason for my reaction and I had to do it fast.

I just started talking, “I guess it’s just that I’m realizing you are all grown up now. You don’t need me to make adult decisions for you anymore. And, you will probably be making a lot of adult decisions from now on; many of them I won’t even know about and may not even want to know about.” Erin was silent, no doubt thinking about some of the things she has done in recent weeks (like the Halloween party). Then a thought entered my head that maybe it was still a case of mistaken identity so I asked her, “So, where did you get the design—did you pick it out off of a wall somewhere?” I was hoping that was the case: maybe a bunch of girls were walking around with the same tattoo—maybe one built like my daughter that was possibly pregnant with my child now… Erin replied, “Actually, I designed it myself! It’s a one of a kind original! It’s nice, though, right?”

That was really the worst answer I could have imagined her giving me. But I had to support her and said honestly, “Well, if you are going to get a tattoo, it should be something original and personal—in my opinion. And, yes: it is very nice. It is beautiful, in fact and it suits you well.” Erin hugged me and thanked me for my support. I would never tell her that this wasn’t the first time I’d seen her tattoo… I asked her why she didn’t tell me before that she was going to get one and she said, “Because you would have never approved!” She was right about that, of course, but if she would have told me right after the fact, at least I could have known it was her and made up an excuse to not end up fucking my daughter. But that was a moot point now. Now it was time to pray that she was not in the fertile time of her cycle when I shot my cum inside of her. There was a good chance of that after all… As an afterthought, I realized I’d most likely fucked her best friend, too—the one she has been staying with. Looking back, the mouse girl was the same height and build as her friend and she did seem like a bit of a slut. I bet it was her idea to drag my daughter there, too. Swinging and anonymous sex was not Erin’s style. But then again, I didn’t think tattoos were until a few minutes before. Perhaps swinging was in her blood as it was in mine and her mothers. Who knows about such things?

The next day was a normal Saturday for us. We spent some time around the house just talking and hanging out. I wanted to get to know Erin ‘the woman’ as opposed to Erin ‘my daughter’. I still saw her as my daughter in spite of having had sex with her, but I was also seeing her as her own independent woman. She was just beginning to live her own life; making her own decisions. And Erin ‘the woman’ was just as amazing as Erin ‘my daughter’.

After a day of talking and getting to know each other on a different level, we decided to rest our vocal chords and watch a movie. I let her pick the movie and nearly choked when she selected the latest Spiderman movie. I had a difficult time paying attention to the movie. All I could think about was the party when I was fucking Erin—cumming inside of her. And she still didn’t know it was me. To my surprise, I was getting hard again; the image of her ass with the sexy tramp stamp bouncing on my lap as my dick disappeared into her clean shaven pussy was the only image I saw on the large screen TV. The only thing I could hear was her whispering in my ear if I had a condom and her moans and screams in orgasm. In hind sight, it was clear those screams were from my daughter; how did I not realize it when it was happening? I guessed that I didn’t pick up on that because it was the last thing in the world on my mind. I remembered all of the diapers of hers that I changed and how careful I was to make sure nothing inappropriate could ever be said about how I took care of my daughter’s little girl parts, and then just 18 years later I had my hand down her pants and was fondling them with lust—and she enjoyed it. I remembered the taste of her pussy and how smooth and clean she was on my tongue.

I was hiding my raging hard-on now and I was going to cum if I didn’t concentrate on controlling my thoughts. I forced myself to concentrate on the movie just long enough for my erection to go down and then excused myself, saying I wasn’t feeling well, before going to bed. Erin asked if she could get me anything and I said I was ok; that it was probably just something I ate. I said ‘good night’ to Erin and she elected to watch the rest of the movie. Before going to sleep, I had to ‘rub one out’. I went into the bathroom like some high school kid and jerked off. But when I did, all I could picture in my head was me fucking ‘the cat girl’. Only this time, she wasn’t wearing her mask. I could easily picture my daughter’s face instead of the cat mask. It only took a matter of about 30 seconds of jerking off before I blew my load in the toilet. And it took much less time for the shame and guilt to sink in. With the erection taken care of, I was going to go and get something to drink from the kitchen, but just as I was about to enter the living room on my way there, I saw Erin was taking care of herself in the same manner as I had. She was still watching the movie and Spiderman was battling it out with the bad guys. Erin’s pajama bottoms danced over her fingers and I decided the drink wasn’t that important—I wasn’t going to embarrass her—so I went to bed.

The next morning I woke up right around six o’clock. That was very unusual for me on a Sunday; normally I would have slept until around 10:00. But then I realized what brought me out of my sleep. Erin was awake already and she was in the bathroom—puking her guts out as quietly as she could. I got up and went to the door and knocked gently, asking if she was ok. She said, “Yeah, I’m ok. But whatever you ate last night, it got me, too.” The toilet flushed and the water ran in the sink. She began brushing her teeth and I went to make breakfast, fearing that she didn’t have food poisoning. I never thought I would wish food poisoning on my daughter, but right now that was better than what was in my head. Erin came out and sat down instead of helping, so I knew she wasn’t feeling well. She asked how I was feeling and I said that I was fine. She took comfort in that; figuring she would be better soon as well.

I made her pancakes (her favorite) and she had a hard time eating them. I told her not to force herself if she was still not feeling well and she thanked me for understanding. We tried to ‘figure out what we ate that was bad’ and ultimately decided the chip dip must have been bad (even though I knew better). I went to the fridge, removed the dip, and threw it away anyway. By mid morning, she was feeling some-what better and asked to use the washer and dryer. I told her to go and relax and I’d take care of her laundry. She kissed me on the cheek and thanked me. She plopped down in front of the TV and turned it on before taking a nap within a few minutes.

I set about doing her laundry and, while doing a load of her darks, found the top she used as part of her cat costume. I just looked at it for a few seconds and remembered how perfect her breasts were. And that was not the opinion of a biased father; I didn’t know I was looking at my daughter’s breasts when I first thought that! She had a large assortment of sexy and racy panties. I was pretty used to seeing them; she started wearing sexy underwear before she even started high school. Even then it didn’t faze me to see the white secretions in her panties; it was just part of growing up. But now it seemed…different. I found one pair that looked like they had been worn recently—probably last night. The goo in the crotch was still wet and shinny. I looked to make sure she wasn’t around and gave them a quick sniff test. The fragrance was all too familiar: the panties smelled just like she did when I went down on her.

Before I knew what I was doing, I was licking the goo out of her panties before tossing them in the washer. I rolled her vaginal secretions around in my mouth, savoring the taste once more; reliving the night I unknowingly ate my daughter’s virgin pussy. What was wrong with me? This was Erin I was thinking about—my daughter—my own flesh and blood! But I couldn’t help myself. After tasting the sweet goo for a few minutes, I swallowed it down, unwilling or able to spit it out. I pushed the thoughts out of my head and finished her laundry, folding each item as I always do for her. By the time she woke up from her nap, her laundry was done. She felt much better after her nap and we talked about nothing in particular for a few hours before she had to go back to her friend’s place to get ready for class the next day. Before leaving, she promised to be back by Friday and I told her to make sure to bring her laundry; I’d gladly do it for her.

The next Friday, Erin called to say she didn’t think it was a good idea for her to come home that weekend. I asked her why not and she said that she was still sick and throwing up. And, whatever she had was contagious because now her friend had it, too. She said she was surprised that I got over it so quickly. I told her she should come home anyway and I would make an appointment for her to go see our doctor. She reluctantly agreed and I made the call. Erin was home by mid afternoon and I drove her to her appointment. I knew she was pregnant now, but couldn’t bring the subject up without raising alarms in her head or possibly offending her (“Is that what you think of me, Daddy?”). We sat in silence in the office waiting room until the nurse called her name. Out of habit, I stood up to go in, too, but she stopped me and reminded me that ‘she was a big girl now’. I just nodded, smiled and sat back down.

After a while, she came back out with a prescription to have some ‘routine blood work’ done. We went over to the lab and they drew blood and took ‘other samples’. Of course, I knew what the lab work was for: they were testing to see if she was pregnant. The results came back a few days later and she went in to get the report. She was given another prescription, this one to be filled at the pharmacy: a prenatal vitamin. When Erin came home the following Friday, she sat me down because, as she said, she had to tell me something important. She took a while to build up the courage to say it, but finally she confessed what I already knew; she was pregnant. I kept calm (mostly because I knew it was coming) and told her that it was going to be ok. She started to cry and I told her not to be upset and that I would help her any way I could. I asked her how far along she was and without hesitation she said she conceived on October 31st. I asked her how she could be so sure and she said it was the one and only time that she’d ever had sex. That was the final nail in the coffin: Erin, my daughter, was carrying my baby.

I asked her about her friend, pretending to wonder how she could have been sick because of her, and she replied, “She’s pregnant, too. As soon as I found out, we went and got her a pregnancy tester; it was positive.” Keeping it light and with a joking tone I asked, “Geez—what are you guys doing—hosting sex parties in her house?” Erin rolled her eyes and said, “No! We are not hosting any sex parties…” I knew that was true: they weren’t the hostesses. She just didn’t add that they didn’t ATTEND any sex parties. I told her she had my support in whatever she decided to do and she said without hesitation, “I’m keeping it—no question! I already love this baby and it’s nothing more than a blob right now.” I was glad to hear that and then asked about her friend. Erin said, “She might be a bit slutty, but she is really conservative at the same time; a bit of an enigma. She is very anti-abortion and is going to keep her baby, too. She just doesn’t know what to do about school, yet.” I told her to offer my baby sitting services to her. I figured it was the least I could do for my own child!

Erin thanked me on behalf of her friend and said it would mean a lot to her. We talked for a while and began going through all of the things we needed to think about to prepare for what was going to happen in a little over 8 months from now. Before long, we had discussed the highlights and she was ready to take her mind off of things. As per our usual, she wanted to watch a movie. And she surprised me yet again when she wanted to watch the original Spiderman movie for the 100th time. The movie was playing and I was having trouble keeping my thoughts focused again, but not as bad as last week. Then I realized I never asked her a question that most dads would have asked first. I turned to her and said, “So, you never told me who the father is…” She just looked over at me and said, “Spiderman is the father, Dad…” I thought that was hilarious but couldn’t let it show too much. I said, “Very funny… Wait: you do know who the father is, don’t you?” Erin looked at me and said, “Of course I know who the father is. Why would you ask me that?” I figured she wanted to keep the details of her sex life private and was perhaps embarrassed that she didn’t know who the man in the Spiderman costume was. I explained my questioning by saying, “Oh, no reason, really. It’s just that you said earlier that it was October 31st—Halloween—and then you seemed to not want to answer who the father was when you said ‘Spiderman’, and I thought maybe it was a guy in a costume that you never got a look at. I’m not judging you: I just know college can be a crazy time and we do things that we normally wouldn’t do in another setting—that’s all…”

Before I even finished what I was saying, I was kicking myself for broaching the subject. I feared I said too much and was worried that she might figure it out. She looked at me a few moments and seemed to understand and acknowledge what I was talking about. Finally she said, “That’s not too far from what happened, actually.” I said, “Then you don’t know who the father is?” She said, “Well, I have a pretty good idea of who he is…I think. But I’m not really sure.” I said, “I guess it would be hard to ask him if he was the guy you were with at that party a few weeks ago…that would be awkward if he said ‘no’. She said that was exactly why she hadn’t said anything to him yet. The conversation dwindled down from there and we went back to watching the movie. But I could sense that something was on Erin’s mind. Call it a father’s intuition; or maybe just paranoia.

After the movie finished, Erin went out to her car for a minute and came back in with a brown bag. She asked me, “If I ask you to do something for me, would you promise to do it?” I said, “Of course, Honey; I’d do anything for you.” She nodded and asked, “Will you put this on for me—just for a minute?” I took the bag from her and looked inside. I was a bit confused at what I saw. Inside the bag was, of all things, a Spiderman costume. I looked at her in confusion and asked her why. She told me to pull it out and I did. It wasn’t until I pulled the costume out that I realized it wasn’t just ANY Spiderman costume: it was MY Spiderman costume! The proof was in the Velcro fly I had sewn into it and my daughter’s virginal blood stains around the crotch. I distinctly recalled throwing it in the garbage and couldn’t figure out how she ended up with it. I was looking at the costume in my hands and she began to explain, “I came home the next morning and you were out running errands, I guess. I was just going about my business when I went to throw something away and I saw this under some trash in the can. When I pulled it out, I recognized it immediately. I panicked and took it with me back to my friend’s—I didn’t tell her, though.”

I looked up at her and my eyes were starting to get blurry. I said, “Erin, you have to believe me: I had no idea it was you! I didn’t know until I saw you with your tat…” She stopped me in my tracks and said she knew that and not to worry; she was ‘ok’ with it. I told her that I was sorry for not saying anything, but I wanted to save her from knowing the truth about what happened; afraid she would never get over it. She said to stop worrying and that she was fine about the entire incident. She said she was a little freaked out at first, but then realized that neither of us knew who the other was and we were just enjoying some random sex. We just happened to beat all odds and ended up having sex with each other. I asked her if she was really ok with what happened and she nodded her head in a casual, matter-of-fact way.

I asked if she was sure she wanted to keep the baby, knowing I was the father and she said, “This is our baby! Of course I’m sure! Daddy, you are the best Dad in the world, and I know you will love our baby as much as you love me.” I knew she was right and couldn’t argue against her. I folded the costume back up and was putting it back in the bag when she asked, “What are you doing?” I said, “I’m putting it back in the bag…” She responded saying, “I see that. But why?” I looked at her blankly not understanding her question. She said, “I believe you made a promise to me. You said you would do something for me if I asked and I asked you to put the suit on…” Erin’s tone had changed to a teasing and seductive tone. I said, “Erin, are you asking me what it sounds like you are asking me?” She said, “Come on Dad: don’t become a prude on me now. Think about it: you have seen every part of me in recent times; you sucked on every bit of my vagina—which was amazing, by the way—we’ve already had sex—twice—and because of a defective batch of condoms, I’m pregnant with your child. And unless I’m crazy, you enjoyed sex with me as much as I enjoyed it with you. Hell: you’ve been walking around with a ‘semi’ since you saw my tattoo! So I know you are thinking about me! Well, I’ve been thinking about you. No one else knows about what happened and it would stay between us. And it’s not like you can get me MORE pregnant!”

She made some good points, but what she was suggesting made me nervous. I said, “That is all true. But what you are talking about is different than what happened between us at the party. When we had sex, we didn’t know we were having sex with each other. But now you are suggesting that we knowingly and willingly have sex and I think that would just make things awkward between us.” She responded by saying, “I’ve known it was you since the next morning and I don’t feel awkward around you. You have known the truth for two weeks and you haven’t been acting awkward; you still love me the same as you always have. I’m not suggesting we start dating, fall in love and try to pass ourselves off as husband and wife or something; it’s just sex—really good sex—but just sex.”

I still wasn’t sure about what she was offering; the taboo of it was so overwhelming. Erin said, “I’ll tell you what, I want to show you something and if you are still resistant, then I’ll accept it and we’ll move on; I won’t bring it up again. OK?” I had no idea what she had in mind, but was nervous about what the ‘something’ could be. I reluctantly agreed to her proposal. She went to her room and was gone for a few minutes. When she came back into the living room, she was wearing her cat costume; heels, mask, no bra or panties—just like at the party. The memories flooded back stronger than ever and my cock betrayed me. Erin walked right up to me and I realized one reason why it never dawned on me that night that the cat girl could be my daughter: she was at least three or four inches taller with those heels on. Erin’s tits were less than an inch from my chest and she only had to turn her head up slightly to look at me. I could feel her body heat radiating on me. My boner was pushing my pants out in attempt to get at her and I was speechless. Erin spoke first: “Like I said; it’s just sex between a man and a woman.” She then looked down at my bulging pants and said, “I can see you want to, so stop over-thinking it and just let go. I reached up and put my hands on her shoulders. But then she took my hands and moved them, placing them on her breasts and held them there. I could feel her nipples pressing into my palms and her breasts felt magnificent. I asked her if she was really sure about this and she took one of my hands and pushed it down her body and inside her yoga pants.

She said, “Feel me—does it feel like I’m sure?” Her still hairless vagina was hot to the touch and she was already wet. No doubt about it, she was sure. My finger already knew where her clit was hiding and went to play. My other hand began tentatively massaging her breast and she unzipped my pants. She found the fly in my boxers and pulled my hard cock out through it. Then she hooked a thumb in each side of the hem line of her pants and pushed them down to mid thigh level. I helped her the rest of the way with her pants, sliding them down her perfectly shaped legs while she stood up-right.

When I was on my knees, my face was at the same level as her bare pussy; her yoga pants where in a heap around her ankles. She lifted one leg and then the other as I slipped the pants off over each high heel. My daughter was naked from the waist down and her vagina was shinny with moisture. Unable to resist, I took her wet pussy in my mouth and sucked down as much of her juices as I could. And the more I sucked, the more she made. She opened her stance as wide as her ankles would allow in her heels while I gave her slick cunt a tongue lashing. Her hands went to the back of my head and her fingers buried themselves in my hair as she pulled my face into her crotch.

Because she kept shifting her stance, I figured out that she wasn’t very comfortable in the heels, so I took her hand and walked her to my bedroom. She sat down on the bed with all of the style and grace as if she was being seated at a five star restaurant. My Erin was a very sexy and sensual young woman! She then opened her legs wide and made the ‘come here’ gesture with her index finger. I went back to eating her out and she put her legs up over my shoulders; knees spread wide and feet crossed behind my back. In that position, I had better oral access to her than the first time. I was able to push my tongue into her vagina and fuck her with it. Erin was being much more vocal now. Hearing my daughter moan in sexual pleasure—from me—was an amazing turn on. The ‘taboo factor’ in what we were doing was off the charts. Even so, Erin knew how to up the game. She said, “Oh, yeah, Daddy! Eat my pussy! Oh my god, Daddy; that feels SO GOOD!” I was emboldened by her ‘smut talking’ and really went to work on her. I explored every part of her vagina with my lips and tongue as I did before, only this time I wasn’t going to stop until she came on my face.

Pretty soon, I got what I was looking for. She grabbed my head, pulled it into her crotch and had a screaming, squirting orgasm. My open mouth caught her gushing fluids and it was a mouthful! She looked down at me through her cat mask and I opened wide so she could see her cum in my mouth. I closed my mouth and swallowed it all; it was delicious! I moved up her body and, as I did, I slipped my hands under her skin-tight shirt; pushing it up over her tits. I took one nipple in my mouth and let my hand play with the other. My cock head was right at the opening to her soaking wet pussy, but I wasn’t ready to push in yet.

I removed my daughter’s cat mask and finished taking her top off of her. With the exception of her high heels, Erin was as naked as the day she was born. A slight smile was on her face as she looked at me in anticipation and she was more angelic than what I had imagined the first time we had sex—when she wore the mask. My solid cock was barely making contact with her slippery pussy and her hips were already starting to rock slightly. I moved forward slowly and my engorged dick began sinking inside of her. As I entered her, Erin’s subtle grin slowly changed; her mouth dropped open and her eyes closed half way. She breathed in through her mouth, gasping for air. When my balls came to rest on her lovely ass, her open mouth slowly changed back to a wry smile as she looked me in the eyes. I began pushing in and out of my daughter’s vagina and our eyes were locked together.

There was no going back now: we were fucking as father and daughter and we were more than well aware of what we were doing. Erin’s arms were wrapped around me; her hands on my shoulder blades and her legs were hooked around my ass as if to prevent me from pulling out of her. My arms went under hers and I had my hands on her shoulders so I could pull myself into her to help my thrusting power. Almost automatically—as if by instinct—I kissed her on the side of her neck. As I did, she tilted her head back, presenting her throat to me. I kissed her there and followed around to the other side of her neck, kissing her just below her ear. I pulled away to look at my daughter’s face. I always thought Erin was beautiful, but seeing her passionate face while in the throes of having sex was beyond words. She was absolutely exquisite!

Our faces were mere inches apart. I don’t know if I kissed her or if she kissed me—perhaps we both moved in at the same time—but we kissed like we had been lovers for years. And every time I pushed deep inside of her, Erin hummed with lust into my mouth. I went back to kissing her neck and under her jaw and she hissed, “Oh yes, Daddy! Give it to me! I want it all of the way inside me! I love how big your cock feels and I want to feel your cum shooting inside of me!” I started going faster and faster as she continued talking. She wanted it harder and harder and I wasn’t going to last much longer. I was pounding into her now and was really enjoying watching her lovely breast being bounced back and forth and around in circles from my fucking her. My balls and thighs were slapping her ass and she began a long, continuous, high pitched hum. I knew her orgasm was building just as mine was.

Erin’s face began to twist: her eyes looked like she was worried; her lower lip disappeared—sucked into her mouth as her orgasm became immanent. My orgasm would wait no longer and I blasted a huge load inside of my daughter’s already pregnant womb. The moment the first of many jets of sperm splashed into her cervix, Erin’s orgasm hit with force. Her legs stiffened; eyes shot wide open and she screamed at the top of her lungs. As our nearly simultaneous orgasms subsided, I let my weight down on her, allowing her tits to press into my chest as I kissed her some more on her neck. I slowly rocked into her and she moved her hips in time with mine. Eventually we rested in that position, with me buried to the hilt in her, and we kissed for a while. I rolled over and she rolled with me to end up on top of me; all while never pulling fully out of her. She sat on my still remarkably hard dick and grinded her hips slowly. While gently rocking on me, she started fixing her hair and when she seemed satisfied with that, she leaned down, gave me a quick peck on the cheek, and said, “Thank you, Daddy; that was even better than the first time! I really liked being able to see your face this time,” before she pulled herself off of my cock.

Erin stood up, collected her clothes and went to her room. I got up and got redressed. Erin took a quick shower and when she came back out, she was dressed in her usual shorts and t-shirt; if unexpected visitors were to drop by, they would never suspect that we had just fucked each other’s brains out. I asked her if she wanted anything to eat and she replied simply, ‘ice cream’. I went to the freezer and said that I’d have some, too, while she went to the cabinet to get two bowls and spoons. We went about the rest of the day as if nothing had happened. Of course I couldn’t stop thinking about what we had done. But it neither felt wrong, like I suspected it might, nor did it feel right—it just ‘was what it was’. I mentioned my feelings about what we did and Erin felt the same way saying, “Like I told you: it’s just casual sex with someone we can really trust—that’s all.” I nodded in agreement but didn’t have anything to add. Erin then said that her friend has been talking about ‘the Spiderman’ nonstop since the party. She wanted to try and figure out who I was so she could hook up with me again. Erin and I agreed for obvious reasons that we could never let her know. We had long since finished eating our ice cream and were talking over the empty bowls when we realized it was late and went to bed—in our own beds.

The next day was just like any normal Saturday for us. We did go out and do a little window shopping; looking at baby items…but it was still a bit early to be buying things like that. It was decided that we would wait until we knew whether the baby was a boy or girl before buying any clothes. After a full day of ‘shopping’ and returning home with nothing, we relaxed with a movie before going to bed. I got up early on Sunday to put Erin’s laundry in so she would have clean clothes for the coming week. Once all of her clothes were washed and folded, I went to her room to ask her what she wanted for breakfast and found her awake but still in bed. Erin thought for a few seconds about what she wanted for breakfast and then said, “I guess what I’m really in the mood for is a ‘quickie’. What do you say?” I didn’t say a word; I just pulled her covers back to find her already naked and she sat up to help me into the same state of dress. I got in bed with her and lay down behind her, spooning her. I was hard in a flash and my cock was pressed between her ass cheeks. I repositioned lower as she lifted her leg and she helped guide my cock to her waiting vagina. I pushed in without ceremony and began gently thrusting into her. I put one arm under her head, wrapping it around to her chest to play with her tit while the other hand went to her clit so it would have a ‘playmate’. We stayed in that position for several minutes and then I tried a new one for us. I kept her on her side as she was, but moved her ‘upper leg’ into a sitting position while her ‘lower leg’ was straight down. I straddled her lower leg and pushed back into her. This position gave me good leverage for pushing deep and she could change the way it felt by moving her upper leg. Erin twisted her upper body so she could watch me fucking her—she smiled with contentment. Erin’s pussy tightened and began pulsing on me and her orgasm brought on my own. Once my cum stopped shooting inside of her, she said, “Can we have pancakes again?” I said, “Of course, baby; whatever you want.” She said, “Thank you, Daddy—that was really good…” I got up to go make breakfast and she got up at the same time. She kissed my cheek, put on a long t-shirt, and helped me make breakfast. We had no problem shifting back and forth between father & daughter and casual sex partners.

Our lives continued in this fashion; she would go off to school and come home for the weekends. We would have mind-blowing sex on Friday to blow off the stresses from the previous week and a quickie on Sundays to prepare for the coming week. Right around Christmas, Erin and I went to have her first ultrasound done. She was only about seven weeks along in her pregnancy, but we wanted to see our baby. Officially, I was there as the supportive father of his single and pregnant daughter, but between Erin and I, I was there as simply, ‘Daddy’. After sitting a short time in the waiting area, Erin’s name was called and she asked me to come in with her (for the benefit of the office staff as opposed actually needing to ask me to join her). We were escorted to the examination room and Erin took her place on the exam table while I just stood in the corner trying to stay out of the way. After a few minutes, an ultrasound tech came in and had Erin lift her shirt up to just below her breasts. I had to be careful not to get a chubby… Erin still wasn’t showing at all; she seemed a bit ‘softer’ than normal, but to any casual observer, they would never guess that she was pregnant. The tech put gel on her lower abdomen and began passing the wand around her belly. It didn’t take her long to find the baby—the baby was still just a single sac of cells; nothing about it to distinguish it from a black and white picture of a fried egg. But Erin asked for pictures anyway: it was ‘her’ baby, after all. The lab tech was very clinical and seemed to have zero emotions about the baby, but she humored Erin and printed several pictures anyway. The tech asked Erin when her last period was and Erin said it ended around October 22nd or 23rd. I did the quick math and realized she was right at the peak of her most fertile point in her cycle on the 31st; she was probably ovulating as I was fucking her with my modified condom. The lab tech wrote the date down and calculated the due date based on the 22nd. Erin told her that she didn’t conceive until the 31st and the lab tech asked how she could be so certain. Erin said, “Because, on the 30th, I was a virgin and I didn’t have sex again after that; at least, not until after I already knew I was pregnant.” Even with the rock-solid testimony from Erin, the lab tech still used the 22nd as the date to go by; she was VERY clinical. Erin’s official due date was July 22nd, but we knew it would be closer to the end of July or even early August.

We went home and the first thing Erin did was put our baby’s ‘picture’ up on the refrigerator with a magnet. It was really something else to go to the fridge and see the ultrasound of my baby being carried by my daughter. I could barely remember the thoughts of guilt and regret when I first discovered that Erin was the cat girl; when I discovered she was pregnant with my child. Those thoughts and feelings were gone; replaced by pride and joy. Erin and I continued our arrangements and things never got weird between us. We managed to keep the sex separate from the other aspects of our relationship. We never cuddled or became overly passionate. Sometimes while having sex we would kiss, but that was different. Once we were finished satisfying each other, kisses were to the cheek or the forehead like you would normally see in a father and daughter relationship. It was very complicated, yet elegantly simple too.

Erin’s belly began to slowly expand as time went on and I was surprised at how it only increased how beautiful she was. I didn’t have a pregnancy fetish, but seeing her pregnant had an effect on me. Perhaps it was because she was carrying my baby, I don’t know. When she was 16 weeks along, we knew that we would be able to tell if we were having a boy or girl soon. Her stomach had expanded enough that most people could tell she was pregnant as opposed to just being overweight—all of her ‘extra weight’ was in her belly; the rest of her body was still her normal size. We waited until she was into her 19th week before getting another ultrasound done because we wanted to make sure they would be able to determine if the baby was a boy or girl. Almost as soon as the tech started searching, she had news for us. But it wasn’t the news we had gone to find out; this was ‘other news’. The lab tech said to my daughter, “There are two now; you are having twins.” We both responded in unison saying, “WHAT?!” She showed us on the monitor and, just like she said, there were two babies growing in there. And, since we knew she started out with one embryo sac, they were going to be identical twins. The tech took pictures of both of our babies. Erin asked if they were boys or girls. The tech positioned the wand around some more, found the right angle on one, and said, “You are having girls.” She moved the wand around and found the right angle on the other baby just to confirm that they were identical and found no surprises; the other baby was definitely a girl, too. Both were healthy and strong; a little small for being in her 19th week, but that was normal for twins. More pictures were printed out and hung on the refrigerator as soon as we got home. We had shopping to do: now we knew to buy girl items and to get two of everything! Erin told her friend the news and she told Erin that she had an ultrasound done, too: she was having a little boy. I was thrilled—even though the baby wasn’t going to have my last name, he was still my son; passing down my bloodline. That was an outdated and single-minded way of thinking, I knew. My daughters would be passing down just as much of my bloodline as my son would after all… but I still liked the thought.
