I did this a few times before I hered a car pulling in to the drive.I quickly got up and tidied myself up and ran down stairs ready to open the door f...r the guy. As I opened the door the guy looked me over and smiled. I invited him in and we headed up stairs and into my room. As we got inside he ordered me to bend over the bed and spread my legs so he could look at my ass while he undressed so I did as he ordered and bent over the bed waiting to see what he would do next. I felt his hand. His dick was already rock hard and twitching. I reached up and with one hand caressed and cradled his balls as the other gripped his base and squeezed out a drop of clear, sweet pre cum. I licked it off him and savored the delicious taste before taking the head of his erection into my mouth. Coating his thick, fat head with saliva and his own pre cum, his cock glided between my lips and over the edge of his head. I felt his massive, thick prick hit the back of my throat. I paused for a moment. See sam was embarssed about haveing a crush on his step sister he knew that this was wrong not natural but sick in a sense but she just turned him on her curves the shape of her ass every thing about her turned him on he would often masterbate to the sent of her dirty pantys and fantasize about fucking her really hard in the ass and the mouth well this was the chance he had been waiting for and he wasnt going to let it slip by seeing that his s*s was growing he asked her if shewanted to play. .. it was "on". We kissed and embraced a few more minutes. He was already anxious, so I suggested we go back to the main bar before my dear friend Missy got worried. I could tell he wanted to say no, or he wanted to ask me to fuck him, or he at least wanted to ask if we could go somewhere else. But he was too shy. It was up to me to ruin him tonight.Back at the bar, Missy kept Brian's friend occupied. This allowed me to up the ante in flirtation. Brian and I chatted and I made doe eyes at him..
