Katie slips down onto his cock

The head of his erection was pressing firmly between her lips and Katie was slowly sinking onto his shaft. She tried to get her feet under her to make an effort to pull away, but the lurching train just tossed her straight back onto his lap. Worse, it **** her down onto his cock and she could feel it creeping steadily up inside her.

Chunky, getting a better grip on her as she fell back on him grabbed her arms to stop her from flailing as he drove his cock deeper inside her! Katie saw that there would be no help from her fellow students as the girls starred in awe and the boys all looked hungrily at her being penetrated! Her only saving grace was that she still had her shirt concealing some of her modesty but little did she know that even that would soon be taken away as two of the boys grabbed the hem of her shirt pulling it up over her breasts but getting stuck under her arms! One boy saw this as an opportunity to use his new school supplies and grabbing out a pair of scissors cut the fabric from her leaving her totally naked and being penetated!!

Katie had to think fast but what would she do in her now nude form surrounded by a group of horny student!!?
