There... there!" she began to tremble even more and lent in closer towards my face. In all her experience she'd not met any man who could do bring her...off like this. I could almost drink in the feelings she was battling with. Sara felt as if she was losing control completely and was not used to that. I let a second finger join the first and pinched down onto the sensitive trigger of her clitoris with my thumb. She dropped her forehead onto my shoulder and leaned her body into me."Fuuuuck! Oh oh. They were no longer horrible and yucky, they were now nice and sexy and my bag of glass marbles went in the bin.What did the shirnk say about doing it infront of girls? - It was bad and naughty to do it in front of girls.

She was mesmerized by the way the inner skin of Drew's rectum was pulled out slightly on the outward strokes and the way the skin of Dave's cock sort of bunched up a bit near the base as he pushed in. She didn't at this stage know that Dave was uncircumcised and his cock had the extra skin that a circumcised male didn't have. Drew felt his orgasm rising. "I'm going to cum," he cried out.
