A Slow Tease (F for M)

[Undeniable Sin]

Hello All. I haven't posted a request thread in a while. This one is slightly different for me, and a bit at odds with my normal desires. Some may even say it's a bit odd. Okay, enough babbling. Onto the idea

                                         School Bus Boredom
Where: I have a craving for a story based around a school bus. Not all scenes have to be bus based, but the majority of the story, I'd like to take place on a bus.
Story line. I picture two older teenagers (17-18) stuck on the bus alone. I picture them being anywhere from not friends to being even hostile toward each other. Still, boredom draws them together. The story would advance from there.
  I have more ideas but I will leave it general. If you have any ideas, or like what you see so far, please PM me. I'd love to discuss.
