"Kiri..." Todoroki mumbles, tapping the back of his phone. Kirishima checks his phone to see a Snapchat notification from  Kitten ❤🤍. He opens it to see I'm going into heat... "Hey, I think Todoroki and I are gonna head to bed." Kirishima says, turning off his phone and grabbing Todoroki's hand. "Okay, good night boys! My ringer's on if you need us." Uraraka says and waves as they leave. "Bye, Uraraka." Todoroki mumbles and essentially speed walks, tugging Kirishima along. They get to Kirishima's room quickly and Kirishima sits on his bed, patting his lap. Todoroki sits down instantly and whines.

"Fuck me, please! Please, please, please please." Todoroki pants, grabbing fistfuls of Kirishima's hair. Kirishima licks over the omega's swollen scent gland and kisses it gently. "Fuck! Please, Kiri I-I need you." Todoroki pants and ruts against Kirishima's thigh. Slick flows from his hole and soaks his pants. "Be a good boy for me, you gotta stay still long enough to take your clothes off. Be a good boy for me." Kirishima coos and grabs Todoroki's hips gently. "Rip them, I don't care just please fuck me- I-I need- nng, Kiri~" Todoroki whines and his thighs twitch as more slick is pushed from his needy hole.

Kirishima doesn't hesitate, ripping Todoroki's thin T shirt and skinny jeans off him. Todoroki cooperates as much as possible and Kirishima rips Todoroki's boxers off. Kirishima flips them and pins Todoroki to the bed, Todoroki instantly offering his neck and spreading his legs. "Do you want here or on your stomach?" Kirishima asks, shoving off his clothes. "Stomach." Todoroki gasps, whimpering in pure desperate need. Why is Kirishima still wearing a shirt? He needs his alpha, needs a knot to help his heat, but Kirishima is so painfully slow.

"Here, kitten." Kirishima says and interrupts Todoroki's needy staring to flip him over and press the hard head of his cock against Todoroki's hole. Why is he being gentle? Todoroki wants him,, so bad. Todoroki rocks back with a whine, begging for more. Kirishima grabs his hips and slides his cock all the way in, Todoroki's slick covering him. "Mm, yes, y-yes-" Todoroki whimpers as Kirishima rocks in and out of him gently. "Harder, please Alpha!" He whines and Kirishima slams into him, pausing to see Todoroki's reaction. "Yes! Like that!" Todoroki moans, gripping at the sheets. Fuck, it feels so good but he needs Kirishima's knot.

Todoroki quickly devolves into a moaning, whimpering mess on Kirishima's cock. He wants his Alpha's knot so bad, it's all he can think about. Kirishima is yanking his Omega's hips back and forth as he slams into him, watching Todoroki moan and grip the sheets. "Fuck, good boy. Good Omega, take me so well." Kirishima pants as he pounds into his little Omega. "Alpha!" Todoroki moans as he comes, arching his back and whining desperately.

Kirishima's knot has already started growing, and with Todoroki squeezing and pulsing around him with his orgasm it's getting bigger. Todoroki pants, throwing his head back in pleasure. "K-Knot me, I need- ah~!" He screams as Kirishima slams his knot into the Omega, groaning as he fills Todoroki with his seed.

Todoroki comes again at the feeling, screaming and clawing at the sheets in the pleasure. "Good boy, stay right there until I can pull out without hurting you." Kirishima says softly and manages to lay down with Todoroki's back against his chest. "You were so good for me today." Kirishima encourages and kisses over Todoroki's scent gland. Todoroki whimpers and holds his head away, leaving his neck open for Kirishima.

Kirishima kisses and licks it, grazing his teeth over it gently. "Mark me." Todoroki whines and Kirishima happily obeys, biting into the claiming area and holding there tightly. Todoroki moans and grabs Kirishima's hair, tugging him down into the bite. Kirishima pulls away and licks the excess blood off, kissing the mark to soothe it. "Good boy, you behave so well for me." Kirishima encourages and nuzzles into it carefully, wanting to be reassuring rather than overstimulating. Todoroki relaxes over it, letting his vision go fuzzy and his eyes close. "There." Kirishima coos softly and let's him go to sleep in his arms.
