You're secretly proud of your cute little bum. You know it's one of your best assets, prominent and muscular. You've never been afraid to flash it, bare, in the changing room, where maybe one of your mates will give it a towel flick or the slap you crave, though none of them has ever done what you dream about and pulled you down, over his lap, for a proper spanking, with the rest crowding around to watch, jeering and egging him on.
Well, you've been spanked now. You hadn't realised quite how much a man like this, with his big, spade-like hands and strong arms, stronger than yours, could make your bum burn. He didn't need implements to make you gasp and wriggle and plead like the naughty little boy he calls you. Not that that stopped him from using them, oh no. You've tasted his slipper and belt, the hairbrush, his collection of paddles and straps, the tawse, the crop, the cane.
And you've tasted him - his cheesy feet after a long hot day, his acrid pits with their tangle of hair, the musk and salt of his balls and taint, the sweet slickness of pre-cum - as he has forced you, not unwilling, to worship his body, punishing you anew when he pretended to find you slacking. Your mouth and nose are full of the intimate, intensely male scent and taste of this man who has reduced you, used you, controlled you, punished you for no reason other than his pleasure and your need, a need he somehow understands better than you do yourself.
But now he is parting your swollen cheeks again, so deep a red that they're almost purple, throbbing with the beat of your heart, and exposing that secret place no ordinary guy willingly shows to another. Flashing your bare bum was one thing, but when he exposes your hole like this you squirm with humiliation and a little fear.
When his big fingers, slick with lube, slide inside you, you feel like you stand on the edge of a cliff. Because you know what's coming, you both know what's coming. He warned you that he would punish you and fuck you, several times, three times, four times, maybe five. That you would be spanked until you couldn't sit down and fucked until you couldn't stand up. That he would fill you so full of his cum that you would slosh when you walked.
