When I was 12, my sister's husband was 29. He would come over to my house, (single mom) just the two of us now, and take me swimming. Our back yard was very privet, so we kind of got a little wild sometimes. We played this game where one would dive in, swim to the other end underwater, and through the legs of the other one. Bob's turn, and I was at the other end. I took off the bottom of my suit, and standing on it, let Bob swim through my legs. Next turn was mine, so I went to the deep end, 8 foot, and dove in. Got to bob, and there he was naked, with a 7 inch hard. Well, now it was out there. I got out, stripped naked, and dove back in. In about 5 minutes, we were in the house, and Bob was trying to get that big thing in my little pussy. Finally it went in, and O M G, that hurt. Bob said it will get better with time, and lots of us fucking. He was right, so now at 19, we fuck everey time we get a chance. After that first time3, HE took me to a Dr. he knew, and got me B.C. I love him fucking me doggie best. We said that my sis would never know, and still she doesn't know.. I waant his baby, and we have talked about it. HOPE HOPE..
