The bus arrives at school, and Katie is sexually frustrated.

The bus suddenly arrive at school and the boys stop and leave. Katie is almost more annoyed than embarrassed at this point, her pissy was tingly and she knew it wanted more, she wanted more, so she decided to stay and hide on the bus, since she had no clothes she couldn't go out there. So she hid under a seat and started to play with her pussy, she must admit that it felt even better now that no one was watching her. She started to go faster, even pulling her clit for extra stimulation. She eventually orgasmed. And it was great. But she soon realised that she was naked and alone in a bus. She needed to get off at the next stop and run home. Which she did. Naked and everything. Once she was home she quickly went to her bed and put the covers round her. Only after the orgasm did she feel embarrassment. And she hated it.
