Harold Walters was another happy addition to our group. Harold was a dentist, and his wife, Joan, was a dental technician, so we were were covered the...e, too. One of those goodies salvaged from the trimaran was a complete duplicate set of everything necessary for setting up a dental office, including the anesthetics and what not. There was even the materials and tools for making dentures. We had not known what we would do with that windfall, but we sure did now. As soon as the Walters could get. Then I shifted, and put her hand on my cock while I moistened a finger and reached for her tight little slit. Jeff tentatively put his hand on my side. I responded by snuggling closer to Sandy. She was watching Jeff closely as he tried to make up his mind. I wasn’t making things easier for him. I reached across Sandy and began to stroke Jeff’s ass. That did it. Sandy quietly excused herself and got up, leaving the two of us stretched out on the bed stroking each other’s buttocks. I waited for. I could feel her pussy squeezing and spasming around my shaft, her little girl squeals and moans driving me mad with passion. I wanted to pin her to the couch and pound away at her with my cock to drive her as wild as she was doing to me, but I had to gentle with this slight-framed first-timer.Somehow she even got more wet between the legs, and I was eventually sliding my cock in and out of her still-tight pussy, though only about 3/4 of my total length. Erica was keeping up the rubbing of. I snuggled in beside her, both of us entered a sensual bliss, My penis was very warm covered with her fluids and my own cum. After what seemed like hours, I finally spoke “WOW! That was awesome!!” “Yes, it was” she replied. ”Was it your first time?” she asked. “Yes” I said. “Me too” she said, placing her hand across my stomach. “I had sex ….I had sex with my sister….” I said as I tried to grasp what had just happened. “Thank you….I’ve always wanted to have sex with you….Always wanted to feel.
