I tried to stop him but he told me that he had an important meeting with his gf . Uff we all know what it is. Then he left. It was just she and me . I...was kind of thinking to do something . The i talked to her i moved close to her . I was moving the topic from normal to sexy talk . She bent down to pick up something i saw her awesome cleavage . My dick rose up too high it was clearly visible . All of a sudden she saw me adjusting my pants . She laughed and asked me are you a virgin . I smiled. Giving a stranger a wank sounded perverse, but these poor guys had not a clue as to the severity of it being done to them to keep them cool, a wank was better than medication, and some of the older woman, got a kick out of keeping the young men happy.I had been sexually active with the guy I had broke up with some four months back and at nineteen it was expected of me to be able to handle most situations, especially when the girls with mental problems were allowed to mix with the boys, and all. All smooth with a hint of summer sweat from walking and warmed by the sun, my semi was soon rock hard. I pinched the dark brown nipple of the smallest which brought forth a moan of excitement. So I tried with the other two and got the same moans.As the four of us exchanged mutual body admiration, I didn't notice the smallest drop to his knees and work on our pants, until mine fell to my feet, along with my boxers. I looked down into the deepest brown puppy eyes and whitest smile ever and then. She got the shock of her life, opened her eyes and tried to push me away! But I didn’t let her go. In fact, I started fingering her faster and rubbing her clit with another hand.Mom slowly started giving up on resisting and was moaning in pleasure now. She raised her ass cheeks a bit and I pulled her closer to me and inserted the second finger in her pussy. I was finally fingering my birthplace and that feeling was ecstatic. Mom finally had her first orgasm of the night and lied on the bed.
