BNHA ONESHOTS

(12) KiriBaku

Smut and Omegaverse warning!!

Just a heads up, Bakugou is an Omega and is in heat. Kirishima is his Alpha and was at work.

--------------------------

“Aahn~!”

Bakugou knew he was in trouble. His heat had come, but his Alpha wasn’t home, so he had to try and please himself as best as he could.

As of right now, he was on their shared bed, ass up in the air as he thrusted a dildo into his slick hole, whimpering. Whenever his heats came, it would be manageable for the first two days, but once the third day hit, he’d be in pain. The excessive hormones would fill his senses and being pleasured would be all he could think about. 

And today was the third and final day of his heat.

“Mmph~” Bakugou moaned as he pushed his face into the bedsheets. “M-more~!” He thrust the dildo faster inside his ass, gripping the sheets with his other hand. 

Kirishima opened the front door, and just as he was about to announce his presence, he heard moans and whimpers coming from their room. He quickly toed off his shoes and put down his bag, his Alpha instincts kicking in to help his mate. 

Bakugou heard the room door open and looked back at his mate, feeling the lust coming from him in waves, making him keen. He stared into the eyes of his boyfriend and came, shuddering and slowly pulling the dildo out of his body.

Kirishima opened his mouth to say something, but was abruptly cut off by a pair of lips smashing against his. He grasped Katsuki’s waist in his hands, fingertips touching, and slid his tongue into his mouth. Bakugou moaned, pawing desperately at Kirishima’s clothes, throwing them onto the floor and proceeding to grind needily onto his thigh. 

Eijiro growled and slammed Bakugou onto the bed by his throat, the smell of the Omega's slick filling the air with its sweet aroma. “You just couldn’t wait, could you?” he purred. “So desperate to please yourself, you couldn’t even wait for your mate. Filthy whore.”

These words only made Bakugou moan and squirm, pushing his hips up to meet Kirishima’s thigh once more for some kind of friction. “P-please~! W-want you, Alpha~!” Kirishima chuckles, putting more pressure on his throat before letting go and dragging his hand down his body.

“I guess I’m going to have to punish you, then, little Omega.”

Bakugou jumped up and got onto all fours, shaking his ass eagerly. “Punish m-me! Please!”

Kirishima hid his surprise and slapped Bakugou’s ass, watching it jiggle. Katsuki had begged for spankings in the past, but he’d never seen him so eager or frantic. Especially during his heats.

So Kirishima happily fulfilled his mate’s desires. Again and again, Eijiro spanked Bakugou until they hit their number. Katsuki usually stopped after 25 spanks, and they’ve learned from experimenting that it would be more painful than pleasurable if they went over that number, but it wouldn’t be satisfying if they didn’t get to at least 20.

But this time, instead of lovingly caressing Bakugou’s ass, he watched as the slick from his asshole ran down his thighs and couldn’t resist. He leaned forward and licked it all up, dragging his tongue slowly over Bakugou’s body to tease. Katsuki whined, but Kirishima pushed his tongue into his stretched hole, resulting in a gasp and needy moan from the blonde. 

“Eijiro~ pl-please~!” 

Kirishima spread Bakugou’s ass apart, reaching deeper into his hole with his tongue. He listened to the blonde’s pleas and cries for more, sloppily eating him out, Bakugou grinding back onto his face.
