She was 12, not fully hairy yet, as she would grow to be, small A cup tits with puffy nipples, and a very nicely shaped body.
I was 14, she was my cousin at 12. Since we were 8 and 10 she always said she was my girlfriend, always saying she loved me, trying to kiss me all the time, and saying she was going to marry me. I sloughed it off saying we were cousins and couldn’t marry anyway. As she got older, she was still insisting on our being boyfriend and girlfriend, even married later in life. Her hair was getting longer, she was getting taller, and taking on a little bit of a shape to her body and waist. I’d see her in the summer in the pool in her bikini and it was starting to fill out nicely, not only that she had an amazing little ass. She knew it too! In her bikini, she would always try to wear “last years” which was small on her whenever I was coming over. She would constantly rub up against me, sit next to me, drape a leg over mine spreading hers out. She even would move the thin cloth around her pussy to the side so I’d see it. I told her she was showing and her answer was “You don’t like it?” I told her I did, but . . . and before I could answer her hand was on my then 12 year old cock, hard but still a bit small. “Yeah, you like it, let me see it” she said. “NO, I can’t do that, someone will see” I answered. Then she took my hand, and led me to the basement. We went in and she said no one could see here. She pulled down my trunks and pulled down her bottom and lifted her top. She only had budding nips then no body to her tits yet. She was playing with my hard cock and pushing her body up against mine so my cock was now against her little belly. “Kiss me” she insisted and puckered up. I kissed her and pushed my cock into her belly while reaching around to her ass cheeks with my hands.
She took one of my hands and moved it around to her pussy. I rubbed on it her telling me how good it felt and me now pumping up and down on her belly. “Does that feel good doing what your doing to me?” she whispered. “Oh yeah, it’s great” With that she pushed my hand more onto her mons, and reached behind her and told me to put a finger in her “back there”. I had to put it in my mouth to get it lubed and stuck it in her. She winced in pain, but told me not to stop. “If you keep going will your baby stuff come out of it, on my belly” she asked. I told her yes and she said she wanted it. I rubbed up against her till I shot my load onto her belly and up to her nipples. I pulled back and started sucking her nipples and she again winced in pain, I was being too rough she told me. I eased up and she told me when i was doing it just right. I noticed as I pulled my finger out of her butt, and moved back she was taking my cum on her fingers and into her mouth. The next afternoon she took my cock into her mouth, something her sister told her about doing to her boyfriend. She swallowed as much as she could and scooped up the rest with her fingers and swallowed it. She put a little into my mouth and I hated it, she told me she liked it and wanted as much as I wanted to give her. “Anytime, anyplace, anyway you want, that’s the kind of girlfriend I am”
That started her boyfriend fantasies even more so and I was willing to go along. By age 12 she was taller, shapely, and quite frankly hot. She was still taking me in the basement, but this time she laid on the couch, totally naked. I told her I wanted to fuck her, to take her cherry. My cock was much larger now 7inches hard, not too thick, straight with a tapered head. She couldn’t get enough of it. I spread her legs, and started licking on her. She panicked with her first orgasm, but liked it. Then as I was licking her to another she pulled me up. “Don’t put it in me but I’m so wet down there, slide it between my lips and shoot on my belly and my pussy” That was the first time she called it a pussy with me. I placed my cock between her pussy lips and she pushed he legs together and I rocked back and forth till she started trembling and cumming, at the same time I shot on her hair and her belly and on her titties. She opened her legs, brought me to her and we kissed. Again she scooped it up and put it in her mouth. I got a washcloth and washed it out of her little pussy hair. I told her I needed to fuck her so bad. I wanted to fuck “my girlfriend” and with that she said we needed to worry about getting pregnant but I could fuck her butt.
We kept that up for a year, at at 13 I fucked her pussy. At 16 I was driving and everyone, even our parents knew we were dating. They said it was OK, as we were second cousins, so they let us. After the first time, breaking her cherry, we used rubbers and at 14 knowing we were going out a lot, her mother took her to the doctor for birth control. By the way, we never got married YET, but when she got out of college at 21 and I at 23, we moved in together.
