A sticky discovery

They mumbled at her as they passed. She had tossed on her pool shift to cover her small bikini but she could still tell that Johnnie was giving her a lecherous look as he went past her in the hall, at least Susan hoped he was. She was heading back to her room for a quick shower when she noticed that the boy’s room was covered with clothes. She walked into the room shaking her head. She reached down to pick up a wet towel and instantly dropped it as she felt a strange wet sticky feeling on her hand that was not right. Her palm was coated with the gooey substance and as she raised it to her nose she knew instantly what it was, it was cum.

She realized that Johnnie must have been masturbating and used the towel to catch his load as he ejaculated. For some reason the smell and thought of Johnnie doing that make her knees go weak, and she could feel her pussy tingling at the thought of her hunky houseguest pumping his cock. Maybe he had been thinking about her? She brushed up against his laptop and the screen came on. She instantly knew what he had been thinking about when he had been doing it, the movie playing on the laptop showed that.

Susan sat down in front of the screen to watch. The man with a huge cock was slamming it into a pretty, big breasted girl from behind. Susan was at once repulsed and fascinated. She didn’t even know that people did it that way. Her husband only fucked her with him on top. The girl seemed to be enjoying it as the man’s huge erection buried itself deep inside the girl with every hard thrust.

Susan realized that her nipples were aching and she reached up to stroke them. As soon as she touched her thick stiff nipples she almost let out a loud moan of pleasure as she was instantly taken with a huge wave of sexual desire. Her pussy flooded with lubrication and she could feel her clit throbbing for attention. She continued to watch the girl take the big cock as she slipped her hand down inside her bikini bottoms. She was so wet she could not believe it. She masturbated occasionally, but she had never been this wet before. Her fingers slid easily between her swollen pussy lips and she found her erect clit. She could not believe how good it felt to her as she pressed her finger against her clit, starting to rub it in a circular motion, all around it, but not quite touching it.

The man had moved the girl on the screen to a sitting position and the girl was now bouncing up and down on the man’s thick cock. He had a shaved scrotum Susan noticed and his balls were drawn up hard against the massive shaft of his cock. Susan had never seen a cock as big as the porn star’s. Not that she had ever seen any hard cock other than her husband’s own what she now knew to be a very average member.
