When I was in college, I had this girlfriend who was into experimenting with new sexual situations. One afternoon, my roommate, my girlfriend and I were all watching TV together in the living room. My girlfriend and I were on the couch, and my best friend/roommate was sitting in the recliner chair next to us as we all sat and watched TV. My girlfriend was lying on the couch next to me, with her head in my lap, and I was in a sitting position. To my surprise, she must have been getting a bit horny, because she started rubbing my cock with her hand on the outside of my jeans while she laid there with her head in my lap. I was shocked, but I also started to get a hard on. I couldn't believe she was doing this with my best friend sitting right next to us, and he did not have a clue as to what we were doing.
She kept stroking me, and teasing me, and I think it was a turn on to her to be doing such a daring act on me in secret. I could feel her fingers touching the head of my cock, and circling around my head, and then stroking the full length of my shaft. I was now at full erection, and she continued to tease me. She was covered in a blanket up to her neck, and now she was pulling the blanket around in order to try to hide my crotch from my friend seeing while he was sitting next to us. Once she managed to pull some of the blanket over my lap, then she started to unbutton my jeans. I couldn't believe she was continuing to play this game even further, and I was sure she would stop at any time and leave me in a total state of arousal. Not a word was spoken between her and I, and I now was moving my hips along to match her stroking my cock. Next, she slowly and quietly began to lower the zipper on my pants, and I could not believe this was going further. I was so turned on, and so rock hard.
After she lowered my zipper all the way, she stopped short of pulling my cock out, and she continued to tease me by stroking above my jeans, and touching me just below my stomach without reaching into my pants. The teasing was driving me nuts, and I just wanted her to grab and jerk my rock hard cock. She continued to tease me, and my friend next to us never noticed what we were doing. This was getting extremely difficult to continue this without letting out any moans of pleasure. I couldn't decide whether to stop this and take her to the bedroom, or just to let her see just how far she would actually go. She looked up into my eyes, and I could see a devilish grin on her face as she saw my frustration.
Finally, she reached into my jeans and wrapped her hand around my cock, and pulled it out from my jeans, but still underneath the blanket that covered us. Oh my goodness, how wonderful this felt. Now she was really stroking my cock, and I was rock hard, and the pre-cum was starting to drip from the head of my cock. Occasionally, she could feel the pre-cum dripping onto her hand, and she would bring her fingers up to the tip of my cock head and rub cum all over my cock. She would get the head of my cock totally wet and slick with my own pre-cum, and then she would return to stroking the full length of my shaft. This was incredible, yet my best friend continued to sit right next to us and watch TV without having any clue as to the pleasure I was receiving.
