I have never seen her that excited.That was a lesson. I knew some very drastic change is going to bring back the fizz. I also knew there is room for a...other cock! Next night while I was soft fucking her in missionary position, started a conversation. That’s the time I usually talk sex. (and take it from me, that’s the right time to coax. You can make a woman agree to anything then.) I asked her how it will be to have another cock inside her. She wasn’t surprised and asked me back how we are. No way. How could Kiki be getting me horny? She was my twelve year old, little sister. But…well…I could see how my mind saw her. Without any predetermined feelings, I could say that for twelve, she was, for a lack of a better word, a stunner. Bright blond hair, green eyes, and like I said, a smile that could make a werewolf purr. Not to mention her tight body. She might have A-cups, but she did not wear a bra, that is for sure. Just thinking about her made me even harder. Unfortunately, what. ..." Before i could finish my sentence she interrupted " I'll be happy to pull your dick out." I grin at her.."Go for it Ariel." She thr reached her hand out of the water and placed them on the side of my shorts and undid the tie. She the pulled them up and down carefully letting my dick out. Watching her reaction to the size of my dick made it jump. My dick was big but more on the girth size then it was length. Past relationship have told me that the length was a good size but the girth of it. She led me by her hand, upstairs around a winding staricase. I felt my cock going hard in my pants. We went into a large bedroom and she began taking her clothes off. She took off her blouse, then her bra, her breasts were bigger than I had imagined, they bounced down. She stopped and then she unzipped my jeans.By this point my cock was throbbing, she pulled down my jeans and then my boxers. My cock thrust out ready for her pussy and she held it and started to masturbate me. My cock was so.
