Bus full of horny seniors

As Rebecca entered the school bus, she blushed. Most of the passengers were seniors in her class, and she knew they were always horny as hell in the morning. Making her way to her seat, she bumped into a tall man who was holding a cup of coffee, which immediately spilt onto his lap.

"Oh sorry!" Rebecca apologized.
"You better be! Now I'm soaked in this stuff!" The senior shouted.
Rebecca, being kind of heart, offered, "Is there anything I can do to help?"
"Yeah," the boy said gruffly, "You can give me that skirt of yours to wipe it up!"

Although the boy was joking, Rebecca took him seriously. The senior was shocked, for the catholic goody-goody with the Porn Star mold tore off her skirt, and rubbed at his crotch where the coffee had spilt.
