Well, I see what you mean about Remus getting Sirius back for the teasing on day 3!
He hated himself for doing exactly what they wanted. That didn't matter right now, he could hate himself later, right now it was time to bring himself off. Fantastic lines! heehee! I just loved Remus's desperate humping and stroking. What delicious visuals of him trying to get so close to Sirius's bed!
And Remus's "Watch me" was amazingly hot. *fans self* What balls he's got! (er, I suppose figuratively AND literally!) The scene that followed was incredible- their eye contact, Remus's little mewls, the come- wow. I can only imagine what was going through Sirius's mind at that sight! *VEG*
