One day she called me on my phone and asked me to come to her home soon if I was free. I reached in 5 minutes and asked what was the reason she called...me for. She said that she had severe pain in her leg (thigh portion) and said she needed pain relieving cream from medical store. I ran to a medical store and got her pain relieving cream, She immediately asked me to apply it and massage her for a while as she knew that I knew little acupressure technique and also her mother-in-law was out of. I made sure to avoid Laura at all costs and just pray to all that is holy that we have more than 10 minutes alone. She is so hot emotionally and physically, just the thought of her defying her sister's desire for me is what turns me on the most. That and her aggressive confidence I even love when she is the dominating party, I just can't wait to see what's in store. The back door opens, and Leah races through. I immediately ask" how much time do we have" to which she replies "Enough. Now get on. I couldn't even tell you the things they made me do after that. I'm having trouble believing it myself. But I don't have any choice now. I just keep doing what they tell me and it just keeps getting worse. I'm trapped now. There is no way out of this. They have those movies. Oh god Dennis! I am so sorry!"I felt his arms go around me and I tried to pull away. I shook my head violently and sobbed, "No Dennis. You don't..."He didn't let me finish. He pulled me into his arms and he held me and he. Oh yes ...." Then with a rush I'm there, the world stops, time stops and all sensation is centred on my penis. "Oh God Bec I'm cumming! Oh yes! Mmmmmh. Oh yes, I'm cumming, I'M CUMMING, I'M CUMMING!" My breathing stopped momentarily as my body tensed. My cock had become the centre of the universe. I exhaled loudly and indescribable pleasure engulfed me as a huge rope of cum flew in a large arc disappearing over my shoulder. I kept stroking and a with a second contraction another load of cum.
