An Eventful Free

You stand up, leaving the spent girl to attempt to tidy up her appearance, and walk down off the bus and move towards your first lesson, physics.

As you sit in the classroom, with the teacher droning on and on, your mind wanders to the events earlier on the bus. The thought of what you did to the girl gives you a raging hardon and you spend the rest of the long lesson playing various fantasies out in your head of what you would have also liked to do to the girl.

A sudden shout interrupts your pleasurable train of thought.

“Cam! As I can see that you were playing so much attention, can you tell the class what the problem is with this equation for beta decay?”

This came from your least favourite teacher, a sweaty old man by the name of David Davenport, and his dislike of you pushes him to constantly attempt to catch you out.

Luckily however, this subject is one of your strongest, and with a calm confidence you answer.

“Lepton number is not conserved, you need to add an antineutrino to balance the decay.”

Surprise shows on your teachers face as you answer the question flawlessly, surprise
that rapidly turns to annoyance before he suppresses the expression.

“Oh, ugh, thank you.”

With that he launches back into this tedious monotone, letting you return to your pleasurable musings.

An eternity later, the lesson finally ends, and you get up to leave. Next you have a free period, what could you do to pass the time?
