He tightened his grip on her waist, forcing her buttocks back against his thickened, demanding prick. It rode starkly against the intimate crease of h...r behind and ground against her for several seconds, and his fingers finally directing his staff at the small round target which he had already stretched experimentally. The knob of his prick prodded without any distinct feeling for a few moments, just the tightness of the entry.He gritted his teeth, holding her waist in a pulverizing grip,. His shirt came off quickly but he left his mask on so I still couldn’t see the face of my attacker. He had a six-pack to die for and the muscles of his chest rippled with every move he made. Then he moved on to his pants, taking his jeans and boxers off in one smooth motion. In doing this he had turned away from me giving me an excellent view of his tight ass. He turned back to me and I swear I almost fainted. There he was, standing proud and erect, a good 10 inches long and about 3 inches. She wanted Saturday to be very special because she had a pretty good idea he would make her pregnant. Then she thought, he is so young and virile that climaxing probably makes his sperm more potent.

Normally I would go on, but I felt and incredible urge to cum in his ass. I wanted to make this dirty fucker mine. My dick, still wet from his nasty blowjob was ready. I stand up behind him and I guide my hard cock, which is more ready than ever, up along the crack of his ass, until I feel his tight hole. I massage the head of my dick.
