Summary
     Accidental sex, humor, random cockslapping.
 

"Oh yeah. Just like that, Hermione. God, yeah." Ron had slipped inside her
tight little arse so easily tonight. It was so much easier than usual! Ron
started pumping, holding her...muscular?...hips hard.
"Mmm," Harry whined, pressing back into Dean's fuck. "Did you get shorter and
thicker? Jesus..."
"Um...what?"
"Huh?"
"Uh, Hermione? Is this some kind of new...p-polyjuice accident?" Ron squeaked,
stilling inside...well, the arse.
"Mmm," Harry purred, pressing back into Ron's crotch. "Slap my cock like you
love to, baby. You know you want to."
"Holy fucking hell!" Ron exclaimed. His second instinct was to pull his cock
out of Harry's arse, like, yesterday. His first instinct...wasn't.
Harry stretched, waking finally. "Ron?" he asked, blearily. "Are you in my butt
or am I having a nightmare."
Ron squeaked again, "I'm in."
Harry made an impatient noise. "I thought you were Dean."
"Well, that's reassuring."
"Are you going to finish?"
"Mate, I don't even know how I began. Begun."
"Began."
"Right."
"Well?" Harry pushed his arse back once in protest of Ron's stillness.
"Yeah, okay. Sort of in it now, aren't we?"
"Mmm hmm."
"All right then."
"Don't forget to slap it."
"Uh, okay?" Ron took one experimental thrust, found his cock to find Harry's
arse more than satisfactory, and then thrust again (though he grimaced the
whole time).
"Slap it," Harry grumbled.
"All right, already! Merlin!" Ron groused. He reached around and slapped
Harry's cock hard, and Harry's arse clenched around him like "Fucking
perfection, mate!" Ron cried.
"Good, now shut up and go. We've got Potions in ten minutes."
"Right," Ron said determinedly. Then he fucked Harry's butt for all he was
worth.
