I feel we are all mature enough to discuss this. I have two storys.
So me and my girlfriend were baby-sitting her little brother and he starts playing halo so we go back up to her room and start fooling around. Clothes come off and she is giving me a blow job on her bed. The position is me lying flat on my back with my feet facing the door and her on her knees bending over and her legs spread over my feet. You can probably guess what happens next. Her little brother barges in asking me for help on a Halo 2 level and saw EVERYTHING. He screamed and ran down stairs. He ended up being pretty cool about it and never mentioned it to his parents or to us again.
My next story involves that girl.
My current girlfriend(well kinda, she dumped me after this story happened)(not that girl^) was getting the pool room in her house re-designed and they moved almost everything out except the big screen and a recliner so my ex was at a sga meeting and we were waiting for her so we could go to a party. Me and my friend, we will call her kelly, are sitting in the recliner watching tv, we are very close and have only been romantic once a few years back so this was not that out of the ordinary. We are sitting there and she moves and her ass brushes my hand, she blushes and we start talking about sex, next thing you know I'm going down on her and all of a sudden I hear "What the f*ck?" I raise up to see my ex girlfriend standing in the doorway. Needless to say she is a tad mad at me at the moment but me and "Kelly" really hit things off.
So what are some of your bad sex experiences?
