Of course there is nothing wrong with that - the more corruption, the better!

I wasn't entirely fond of the prompt either, but as I've gone into OTP-ish mode regarding Mochi and Miyasaka, I really didn't feel like letting Miyasaka do Onozuka. Also it'd piss Kikuchi off, so...

Now my only problem is that fisting needs words to work: the usual fandom crap where the guy takes it the first time... that is so a no-go for me. Blergh. Maybe I should finish the Fest fic, actually, before I venture into the murky waters of anal play. No pun... :D
