Katsuki knew the moment his boyfriend got the itch as the blond called it. They had been dating for almost a year, so Katsuki already knew when Tetsu got the itch to dominate him. It excited him in a way that he could never explain. Katsuki knew he was good-looking, even beautiful, every ex and fling that he had always praised his looks, but nothing beat the way that Tetsu looked at him, the hunger those dark eyes held every time they rested upon the explosive hero was exhilarating. The kisses that felt as if the taller man couldn't get enough, and the way those dangerous hands worshiped Katsuki's body were the reasons that Katsuki was always on cloud nine with his boyfriend. Today...those eyes were dangerous. "Katsuki," Tetsu growled softly in the blond's ear as they were standing near the doors of the train, the hulking teen behind the blond, wrapped an arm around the tiny waist and pressed their bodies together. The monster bulge that poked Katsuki was enough explanation, "I want you now, babydoll." "Tch, we're in a train, iron for brains! We can't-hey!" Katsuki started to say when a hand slipped inside his hoodie and cupped a fat pec, the blond's face turned red as he saw a few old ladies looking at them while whispering at each other. He felt sharp teeth nip at his neck, followed by a warm tongue that always made him shiver. "I don't care, they can look. I say I want you, and I want you now!" Tetsu said as he pushed Katsuki against an empty seat, the blond bounced once and his eyes widened when Tetsu began to unbutton the blond's jeans. He got them off and smirked when he noticed that Katsuki didn't have any underwear and that it was wet and pearly white where it was already brushing against his cunt. "Mmmm, fucking hell, babydoll. You're already wet and without my permission." Tetsu unbuckled his belt, and Katsuki began to breathe harshly, he spread his legs as he forgot about everything and everyone. His carmine eyes were glued to the piece of leather in his boyfriend's hand. It was dark charcoal and on the inside, the words 'Tetsu's Pretty Doll' were embedded in the leather. Katsuki could read them as the man folded the belt and caressed a pale thigh. Tetsu sat between the blond's pretty legs, grabbed him by the asscheeks, and pulled his cunt near his face. He let his tongue swipe from clit to hole, circled the pulsing hole, and fucking it as he let his quirk turn the flexible muscle into steel and Katsuki wailed as he came unexpectedly. "Oh my, that's such a pretty cunt, sir. You're lucky." A man said as he recorded them, Tetsu smiled and cleaned Katsuki with his tongue, he lowered the boy and rested the belt on top of the blond's chubby cunt. "Thank you! It's delicious, you can look and record, but he's mine." Tetsu smiled and kissed Katsuki on the lips softly, "Baby doll, I'm gonna start. Your color?" "Green, Tetsu, please, please!" The blond pleaded, and with another kiss, Tetsu readied himself. "You beg so beautifully, babydoll. I'm gonna spank you, cum anytime you want. As many as you can, baby. Drench the belt and the seat, okay?" He waited for a verbal confirmation and when Katsuki croaked that he understood, Tetsu let the first spank fall on Katsuki's inner thighs. With every spank, he got near the enticing cunt. Katsuki could only scream and moan in pleasure. He felt a few hands soothing him, playing with his nipples, brushing his hair back, trailing down his torso but they never went lower. "TETSU! Spank my cunt! Please, please!" "Wanna cum for me? I bet that if I do, you will cum all over your pretty self." Tetsu urged as he began to rain hard spanks with the belt, not hard enough to imprint the words on Katsuki's groin, but hard enough to throb. With another wail, Katsuki squirted, creaming the belt as Tetsu continued to tap in quick successions his clit. It sent shocks of pleasure down Katsuki's body. Tetsu pulled the blond up by his hips and sat him on his lap, then with one final spank of the belt on each asscheek, he imprinted his name on each one, Katsuki moaning into his neck as he came once again. “You did so good, baby. So fucking good, I’m so proud.” Tetsu kept praising the boy as people kept taking pictures of the used blond. Tetsu let Katsuki rest on his back on the seat again and they shared a kiss. The cameras captured how ‘Tetsu’s Pretty Baby Doll’ was marked on the soft skin of his thighs and how the flushed red cunt was still creamed, Katsuki smiled at Tetsu and grabbed his hand. “Th-thank you, Daddy.” “Anytime, love. Anytime.” End
