Trying to think how to justify what I was doing. My mouth was running wild. Just spitting out parts of random words and sounds as my brain struggled t... catch up. Then I seen her mum smile a little. Did she think it was funny? Was she happy she now had a way to get rid of me? It was that break in the panic that gave me time to realise that she was touching herself through her nighty.She clearly seen me stop panicking and just fixate on her hand, as she started gently rubbing herself again. Then. Lisa had set up a camping trip and told her mom that we were taking Wanda with us. She had agreed because she knew Lisa and I wouldn't do anything with Wanda with us. It wasn't until after we got there, got set up, and were sitting back partying that I found out that Wanda was still a virgin and that Lisa wanted to be there with her when she gets deflowered. When we got into the tent and got our clothes off, you could tell Wanda was very nervous. So we are laying there and I'm sucking on her. I love you Bill." Once again I heard this name. "Ok, what's with the Bill thing?" I asked. She replied just like her sister even though they had never talked to one another about their day with me. "After what we have done, Grandpa or Teacher just doesn't seem right." she said. " I told her that her sister did the same thing. "When we "Play" with ourselves we would fantasize about everything we did with you and call you Bill. When we did it to each other, one of us would pretend to be you.". .it feels great and it doesn't hurts a bit. Fuck me now, I hear myself saying and than a feel that beautiful cock pushing his way into my ass. I am so aroused and well lubed that it slides all the way in until I feel his balls pushing against mine. He starts pumping my ass as I'm thinking "why didn't I did this until now? I love this, I'm now sure that I'm so gay". My wife stops them and we switch with our legs up and also switch partners. He holds my legs up, his dick is sliding all the way.
