She even let out a little squeak: a few of the other girls looked round but we must have looked quite innocent, staring up at our beloved teacher, so ...hey turned round again. Marnie took my hand and, quickly, kissed my fingertips, licking her own cunt juices. That was a real turn on. I wanted her to touch me so much, but at that moment the bell went. I was cross, frustrated, but then I realised we had the whole weekend…We didn’t have much chance to chat afterwards, because the other girls were. For some reason though, I've never been with a black granny, it just never worked out. Last week though, I met a woman, Sylvia, on AFF. She's 67, 5'9", with big heavy tits and a wide ass and I couldn't believe my luck. She lives just a few towns over, and after we texted and exchanged some pics (she has fucking incredible tits...big dark nipples, and a fat little pussy with a grey bush), she called me. We talked for a good while, the whole time my cock about to explode at the thought of her. .I thought..." "You thought I was Lisa! You sick fuck!" I was shitting myself, Amanda would tell my parents for sure and then both Lisa and I would get killed or worse, disowned. She could easily say I raped her. "Please Amanda don't tell anyone about this" I pleaded. "Do you really think I'm gonna go around telling people that my little brother and little sister fuck each other?". she growls at me. "No. I'm sorry. I just thought.." "Wait a minute, did you come here thinking that Lisa was. Both of us are medium complexion and are normal in every aspect. In fact, we were like brothers. I like him a lot, so we hang around together. Sometimes, after dinner, we used to sleep together (during holidays) or we will go to our own houses. Our parents were proud of our friendship and never minded us since we go to the same school and have the same timings.Now, the fun part starts, since we were together all the time, nobody told us to maintain a private space from each other. That means we.
