He suddenly remembered, Nancy coming over and they having sex in the living room downstairs. His cock twitched. Mario could remember that her fantasy ...id not end exactly as she wanted. He felt guilty a little but naughty as well. Her fantasy as he knew, mostly involved roughness, domination and the anal sex. As he very quietly came down to the kitchen, he was surprised to see Nancy in the kitchen. She had washed the couple of dishes lying in the sink. She was all dressed to leave but Mario. She threw her arms around him. Her hips matched him stroke for stroke. Her legs reached up around him, and he felt her heels poking his ass, egging him on. He felt the pressure growing in him again. He heard her screaming, calling his name. He thought of the derivatives again. They barely helped. In a minute, he felt a rush of intense pleasure as his sperm shot from him. Lisa screamed louder, the yell rising to an incredible pitch, as she climaxed with him.Jack felt himself growing. "mmmmm..." she moaned to herself, a little louder this time.Her pussy was aching to be used and she wished momentarily that she had thought to bring her vibrator, as that would have sped up this process significantly.She continued to stroke and rub her pussy, working herself closer to orgasm. One finger slid inside her pussy and she began to slide them in and out, using her thumb to work on her clit at the same time. Her other hand continued to play with her breast, pinching and flicking at her. As much as I enjoyed his company, I'd gotten used to having a fair amount of solitude. Having him here was wonderful, but almost overwhelming.On his way out the door, I pressed a twenty into Mike's hand and suggested he pick up some condoms. He laughed and shook his head. "Lynne, I may be a broke college student, but I think I can pay for my own condoms."I snagged his collar and pulled him in for a kiss. "Well, I'll be benefiting from them, too." Good point." He folded the bill and slipped it.
