Katsuki kisses Izuku on the lips passionately while his hands trace his nipples.
“What’s your safe word, love?”
“Katsudon,” he whispers, chasing Katsuki's lips.
Katsuki chuckles as he grabs the blindfold and starts situating it over Izuku’s eyes. “Turn around sweetheart” He whispers in his ear. Izuku complies with the order. Katsuki begins putting Izuku in position.
Izuku has his face in the mattress with his ass in the air, pussy on full display. His arms are bound right underneath him. Izuku wiggles a little bit making sure he’s not uncomfortable. Katsuki stares, he feels himself getting harder by the minute as he watches Izuku’s plump ass jiggle with his movements. His pussy drips with slick as he becomes more and more aroused.
Once Izuku is ready, Katsuki starts with his feet. He lightly brushes his hot fingers across his toes, before leaning down and sucking on each toe. A small sigh of contentment comes from Izuku’s mouth as pleasure starts to rise. Katsuki licks up and down Izuku’s foot, making sure every inch gets sucked.
Katsuki then moves and starts massaging his ass. Rubbing in circles with his calloused hands that almost cover Izuku's ass cheek. Katsuki grabs a rubber flogger, and with a quick motion, smacks Izuku’s ass with it. Izuku yelps at the sudden feeling of pain on his ass, but it quickly turns into pleasure as Katsuki rubs the spot he smacked. Katsuki strikes another hit to Izuku’s ass. This time Izuku moans into the mattress. His arousal now blocks out any pain and replaces it with pleasure. Katsuki hits again, and Izuku chases the hit by arching his back more, trying to get another sting of pleasure.
Katsuki puts the flogger down and starts kissing the spots where he hit. Slowly moving towards Izuku’s anus. With a slow long swipe of his tongue, Katsuki licks the hole before plunging his tongue into it. Moans fall from Izuku’s mouth as Katsuki licks around the rim before returning, using his hands to squeeze and spread his hole more.
He moves his hands down to Izuku’s pussy folds and spreads them. One hand stays on the folds, while the other moves down to rub Izuku’s clit. As Katsuki eats Izuku’s ass, he buries his nose into his cunt, taking in his lover's sweet honey mint scent.
Once satisfied, Katsuki gets back up and slowly fingers Izuku, ensuring he’s completely open. Izuku moans softly as his pussy is opened up.
Katsuki then picks his hands up and drops them quickly to give Izuku a spank on both sides of his ass. Katsuki smirked as Izuku’s ass jiggled again. He hits his ass a couple more times, every hit being harder than the last one.
Katsuki picks up the whip again and lightly smacks Izuku with it. He rubs it on Izuku’s pussy, lightly smacking it before he quickly gives two more harsh hits to both sides of Izuku's cheeks. He repeats this, letting every hit to Izuku’s pussy increase. Izuku is now jumping and twitching at every hit.
“Mmhhm Kacchan” he moans needing.
Katsuki, deciding to give Izuku the pleasure he wants, grabs a vibrator and starts to stimulate Izuku’s clit. Izuku moans softly as the soft vibrations soothe his clit after being smacked. Katsuki removed the vibrator, smacking Izuku’s pussy with the flogger again, then putting the vibrator back to his clit. A hiss comes from Izuku at the sudden change in pleasure.
Katsuki starts to amp up the vibrations. Izuku’s moans start coming out louder.
“Ah, ahh, Kacchan!”
Katsuki smacks Izuku again with the whip while the vibrator stays on his clit.
“Oomph!!” Izuku moans into the sheets, attempting to keep control of his voice but failing.
Katsuki fingers Izuku’s pussy as the vibrator is still on his clit. He then quickly removes the vibrator and starts to finger fuck Izuku harshly. Izuku lifts his body as Katsuki repeatedly hits his sweet spot.
“AHhh, there Kacchan Please!” Izuku moans as he gets closer to his climax, but before he could, Katsuki pulls out. He grabs the whip and smacks Izuku’s cunt hard with it.
“AHH” Izuku yelps, not expecting it. Another hit smacks his ass cheek again. Making Izuku twitch from the abrupt pleasure and pain.
Katsuki leans down again and kisses Izuku’s ass and then gives it a deep bite, before moving on to the next cheek and doing the same except this time he sucks on it after biting.
After showing love to Izuku’s ass, Katsuki grabs a dildo. He rubs lube all over it before placing it at Izuku’s entrance. He leans towards Izuku’s ear and whispers in his deep rough voice.
“Don’t drop it baby” with that being the only warning for Izuku, Katsuki shoves the dildo into Izuku’s cunt. Izuku gasps at the sudden intrusion. Katsuki leaves the dildo there as he grabs the whip and vibrator again. He puts the vibrator on its highest setting and places it on Izuku’s clit. Once that’s situated, he slaps Izuku hard, making the flogger make a crack noise.
“AAH KACCHAN! TOO much!!
Izuku can’t control the spasms that cause him to jerk around as his clit and sweet spot are both being pleasured at the same time, the whip just making things more intense for him.
Katsuki continues the whipping until he sees Izuku shaking, getting ready to have an orgasm. Katsuki grabs the vibrator and the dildo and swiftly removes them from Izuku. Izuku whines with the loss of pleasure.
“You didn’t think I was going to let you come on some tiny ass dildo, did you Deku~” Katsuki whispers in his ear before licking and biting it.
“Don’t you want to come on the real thing?”
“YES yes, yeess! Please Kacchan! Fuck me! Use ME!” Izuku begs.
That’s all Katsuki needed to hear. He aligns his cock with Izuku’s hole, and he thrusts into Izuku’s pussy in one swift motion. He doesn’t give Izuku time to get used to his massive size as he starts thrusting into the hole at a brutal pace. Izuku knew that if he wasn’t strapped in, his whole body would have been thrusting forward.
Izuku’s eye’s roll upward as Katsuki hits all the right spots in his pussy. His tongue lolled out of his mouth as Katsuki’s balls smack harshly against his clit.
“OH my go-” Izuku’s moan was cut off as Kastuki grabbed his hair and yanked it.
“Cum for me baby. You can do it.” Katsuki said, smirking.
“KAAAchAAn I-I’m CUUmMMiing!!!”
Izuku squirted hard while Katsuki emptied his cum in his lover. Katsuki pulled his cock out and then reached his hand around Izuku’s stomach and started to play with his clit harshly.
“KAACHAN WAIT! SToP!”
Katsuki kept going and with one final swipe and pinch, Izuku squirted again. Usually, when he squirted, it would stop after a second, but this time it kept going. Izuku kept spasming as Kasuki watched in awe and pride. He was thrilled to see Izuku filled with pleasure.
“Holy shit, it isn’t stopping,” Katsuki said with astonishment.
“Why won't it stop Kacchan!” Izuku said, still with his tongue out and body spasming. Katsuki drank some of the juice coming from his lover before moving to kiss Izuku’s tear and drool-stained face.
After Izuku was finally done squirting, Katsuki unbounded Izuku and cleaned them both up. Izuku was still shaking from the overstimulation. Once done cleaning, Katsuki cuddles up with Izuku.
“It was like a never-ending cycle of pleasure,” Izuku said in amazement.
“That’s because I’m amazing, love” Katsuki said smugly before kissing Izuku on his forehead. Izuku giggled at his response and kissed him on the lips “You are amazing Kacchan.” They both drifted to sleep, basking in each other's warmth and company.
