Her good friend Megan was a bit of a troublemaker. Before I could answer she was already up and running to the basement to retrieve the bottles. "Mark... is vodka good?" She called out. I was normally a beer kind of guy, like every other man. But this time I figured vodka would do. "Sure, why not." I yelled back. Soon she was back in the living room holding two big bottles of Grey Goose with this cute little grin on her face. I felt my cock stirring beneath my jeans as I watched my sister twirl. She stands drop her jeans to her knees bends over the desk and props her hands against the desk and looks over her shoulder and stated unless you want blue balls. It didn’t take me long to make the decision. I stood drop my pants and slid my hard cock into what has to be the hottest wettest tightest pussy I been in. We both moan in ecstasy. She immediately starts moaning as I started to pump. After about a minute of this I felt the all too familiar feeling. I was about to cum and as I attempted. I was eagerly waiting for this opportunity. At any moment, I will get a chance to see her boobs. Now she told me she can manage and asked me to leave the room, to my disappointment.She came out of the room and I was waiting outside. I saw her feeling very uneasy. I asked what happened.Mom: Son, the blouse the very tight.Son: Let me see.Without asking her permission, I removed her pallu from her shoulder put it on the floor. She was surprised and blushed.Son: This blouse can tear at any. I realized that he was much bigger than his son and I touched his big tool with one hand, he stirred, he opened his eyes and stared straight into mine. He was smiling when he asked if I had enjoyed myself. I smiled and said I did and he had fucked me better than any man, including his son. I told him I wanted him in me again. He asked me if I was sure. I then said, “Doug I may be your daughter-in-law but I want to be your lover as well”. He then again got between my legs and proceeded to drive.
