Chapter Text
As soon as Remus's back hit the bed, Sirius was kissing his face, his mouth, down his body, and Remus must have actually zoned out a little bit there because one moment Sirius was kissing his nipples, the next he had already reached his prick, which was standing up at least somewhat, despite Remus himself in fact being mostly too tired to stand, because cursed, post-full-moon horniness and oversensitivity, and was taking it in that warm, skilled, wonderful mouth. The mouth was soon joined by fingers, wonderful slick fingers probing at his entrance and he woke up a little from their coolness.
'Siri... I might fall asleep on you if you fuck me. I'm not saying no, I'm just warning you, I'm exhausted.'
Sirius looked serious.
'But will you enjoy it?'
'Yeah, kind of hard to imagine me not enjoying you fucking me.'
'Then let me fuck you. Let me pleasure you. If you sleep, you sleep. If you don't, good for us both, I guess. I just wanted to know if the full moon makes you more sensitive to pleasure as well as pain.'
'It does. But I'm always too tired to do much with it.'
'Just let me pleasure you, then. Let me kiss the curse away.'
'It doesn't work like that and you know it.'
'It's just a song reference. But if it makes you feel better at all, it's worth it.'
'You have my blessing.'
And Sirius lowered his head again to lick and suck while he fingered Remus. And it was pleasant, in a distant way, being slowly opened up and suckled while him mind strayed on the cusp of wakefulness and sleep. He woke up a little more when Sirius pushed inside, no pain, just pleasure, his body even more oversensitive inside to it.
'Mgonna cum soon,' he muttered indistinctly but Sirius caught it.
'That's the whole point, my beloved.'
So he let himself float on the mounting waves of hazy pleasure and the tension build in his body until he came all over Sirius's chest. The Animagus whimpered, dowright whimpered, and came as well.
Remus was asleep before Sirius magicked them both clean.
