What if I wanked in chemistry?
Disgusting. What would make you wank in your chemistry class?
Well, I was bored, there was nothing happening and it seems like a good thing to do.
I hope no one saw you. It is highly inappropriate to masturbate in such a public place like a classroom. You could very easily get expelled.
At the time I did it, I thought it was a good idea and now I recommend it to everybody.
Do not recommend that to people just because you got away with it. You shouldn't have masturbated in public, it is disgusting for the other people to be subject to that. Also you could be put in a registry if you get caught.
