Nothing else to do now but brace.

At first Katie hoped that it was "Chunky's" arm that was pressing against her but suddenly realised with a sense of horror that the he had managed to release his cock and his erection was pressing up between her legs.

If Katie had had qualms about making a fuss when he was just playing with her panties they were quite small to the feeling of horror she felt at the thought of yelling out that this boy is rubbing his cock against her. She'd just die of embarrassment. She didn't want anymore attention b that what she had.

Swearing softly, Katie flung little dagger looks over her shoulder, unfortunately totally failing to wound the boy laughing at her. Things couldn't get much worse, she thought.

She was wrong. The bus roughly went over a hump. At the same time the boy lifted Katie and let her sink down again.

Katie's eye went wide in shock. He wouldn't. He couldn't. It turned out he could and would. The head of his erection was pressing firmly between her lips and Katie was slowly sinking onto his thick cock.
