When I was in high school, I took the virginity of my 1st wife when we were 15. We actually took each other's opposite sex virginity as I had sucked a few guys off and had let a couple of them ass fuck me when I was 13 and she and her best friend had been eating each other out at 13 too. I was lucky enough to end up living at her parents house although I had to sleep on the couch but we would fuck and suck like rabbits as soon as her parents were gone to work in the mornings or whenever they went shopping at night or on weekends. But my confession is about her sister.
When I started seeing my future ex wife, her sister was a 13 year old brat built like a boy and would run and tell her parents if we even so much as kissed but that all changed shortly after she turned 15. She went from nothing to I later found out 34DD,22,36 in what seemed a month! And yes, my young cock noticed as I was getting a hard on whenever she was around and I would fantasize about her when I was fucking her sister. I would even spy on her when she was in the bathroom, seeing her nude in the shower or getting ready for bed at night. Then, one Saturday as I was doing the laundry, she came down to the basement wearing a wife beater and her panties and looking so damn fuckable that I sprouted a major hard on even after fucking her sister who was still laying in bed and she asked if I needed help. I tried to act all hard and told her I could do it when she said she knew I was spying on her all the time and asked if I would like to see her naked body as she pulled the wife beater off and pushed her panties down. I tried to stay in control but she smiled and said she had seen her sister sucking me and she wouldn't say anything as she undid my pants and knelt down to start sucking my cock! I could barely breathe as she sucked away and played with my balls there with both of us naked in the basement. She sucked on me for a few minutes then, pulling my cock from her mouth, she asked if I would like to eat her pussy.
I pulled her to her feet then buried my face in her firm young tits and sucked both her nipples before sitting her on the dryer, spreading her legs and licking and sucking that fine young c**t until she came then stood up and pushed my cock into her wet slimy puss and fucked her until I shot my wad into her tight c**t.
We realized what had happened and she ran to the bathroom and I heard the water run as I hoped she was busy washing out her fuck hole as I was worrying if her sister had heard anything and felt as if the whole world knew what we had done.
Later that day as I had my cock buried in my girlfriends mouth, her kid sister looked in and showed me her big tits and mouthed that she would do me later as I came.
We did continue to suck and fuck each other and, even after my ex and I divorced, we continued to have sex whenever we could. I'm just sorry I never got the chance to fuck their mother!
