Oh man, can you imagine finally training brat!Nick Fowler? When he finally behaves for the first time all on his own?
He's on his back, legs spread wide for you to play with him. You've been sucking him off for the better part of half an hour, teasing him to no end. He hasn't held in a single noise, just like you told him, you wanted to hear how much he likes it when you suck him. He's kept his hands on the pillow beneath his head just like you told him. He's kept his trembling legs spread for you without having to be scolded. He's been the epitome of a good boy. He thought that would have earned him a treat.
And it has, just not the way he thinks.
You keep playing with him, suckling at his tip, making him whimper and beg for release. So you decide to make him choose: cum in your mouth while you finger his ass, or cum in your pussy while you ride him.
He nearly has a break down and whines that he wants both. He's deep in subspace so it doesn't make much sense when you tell him that he can't have both. He whines again but finally decides to cum inside your mouth (it was closest to his dick). You waste no time slipping your fingers into his ass and taking him back into your mouth. It's a blur for him from there. All he can remember is blinding pleasure, his hips rocking desperately back on your fingers and up into your mouth, and his whorish moans and screams filling the bedroom. When he does cum, his thick thighs shake as you swallow him down, his back arches, and he actually tears a hole in the pillowcase. Then all he hears is soft coos of his name, your hands caressing his face and head gently, and the words "good boy" being rained down on him over and over and over.
He's smiling, purring, and clinging to you like his life depends on it. He finds out that being a good boy isn't so bad after all.
