Maybe this was a bad idea. Surely Sirius could have just kept his mouth shut and avoided all this, nevermind that he was enjoying this thoroughly. But as he sits on Remus's lap, his fingers grazing his sides so slowly just to tickle him and then a mouth clamps down on the side of his neck to suck a new mark on there.
Yeah thats what this whole thing was about.
As they had decided to keep their relationship private, people kept coming onto Sirius, and him being the attention whore that he is, (both self proclaimed and harshly grunted into his ear by his beloved while his fingers were wrapped loosely around his cock) welcomes their advances to a certain point.
But Remus Lupin, that man was a possessive fuck. Curse those who claim otherwise to Azkaban because they'd be lying. What other reason would there be for his boyfriend to lay him down, face pressed to the bed and his hands tied behind his back and to tease his prostate with just one of his long lean fingers.
Its not that he can't put more in, Remus had made sure he'd be well lubed and his cock has been inhabiting him for months for merely 2 fingers to not fit.
But Remus was a cruel man and he made sure his lessons stuck. Sirius would beg to be filled more, he can feel the empty space beside the singular finger and he could writhe and beg and cry but Remus would edge him with just that stimulation to keep him going over and over again untill Sirius loses any control he had over his body and cums all over the sheets and his torso.
Sometimes he'd be extra cruel, if they're both sober and of sane mind Remus would think of just how much the whole thing pisses him off. Those nights Sirius doesn't know if he wants to keep this game of his going or end it all for good.
Could he change his behaviour? Yeah certainly. But that means Remus wont go feral over him and thats something he's not willing to give up.
