CW: cheating

Todoroki is dating Deku and Deku's hooking up with Kacchan.

"I got you something." Todoroki purred, holding up a paper bag. Izuku curiously sat up, eyes on the bag.

"You didn't have to, Shoto!" Izuku said as he was handed the gift, eagerly pulling out a dark green lingerie set. It was a beautiful three piece, a top, bottoms and garter

belt. Underneath it in the bag lay a pair of matching thigh highs.

Izuku swallowed thicky, cock twitching in interest. This was probably the kinkiest thing Todoroki has done their entire relationship. Izuku felt bad that he immediately thought of how Kacchan would react to

seeing him in this. He pushed the thought aside as he thanked Todoroki.

"I was thinking maybe you could wear it tonight." Todoroki hummed.

"Definitely."

Todoroki smiled and leaned down to give Izuku a kiss.

"Don't forget the class is doing movies tonight." Todoroki reminded

before leaving Izuku's dorm.

Oh he remembered all right.

When movie night approached, Izuku changed into the new lingerie and hid them beneath sweatpants and a dark shirt. The boy went down to the common room to join the rest of the class. He sat next to his boyfriend with a

small smile. Even just having it on underneath his clothes was making him horny. But Izuku knew Todoroki wouldn't even have sex on his mind until after they were in his dorm room.

Kacchan on the other hand....

The blond walked in late, the only spot left on the loveseat Izuku

and Todoroki were already sitting on.

"Scoot over." Katsuki demanded. Izuku immediately obeyed, giving him a space next to him to sit.

Katsuki grunted as he took the seat. The class knew Izuku and Bakugou were on better terms now, but no one knew just how good those terms were.

As the movie started, Izuku curled into Todoroki's side, enjoying the warmth.

Blankets were passed around and Izuku pulled one over himself and the two boys besides him. As soon as the cover was offered, Izuku felt a hand on his thigh, slowly and carefully trailing up. Izuku

swallowed thickly, Shoto was right there! Kacchan what are you doing?!

Izuku nuzzled into Todoroki's neck, throwing a quick glare to Kacchan. The blond only smirked in response, continuing to slowly feel him up. Izuku bit his lip as Katsuki's hand brushed his dick. It trailed

up further, finding his waistband. Izuku squirmed, cock aching with want.

Katsuki dipped down, feeling the lace hidden underneath. He raised an eyebrow, glancing to the green haired boy who was trying so hard to ignore him. Another glare had Katsuki retreating. Lingerie, huh? He

couldn't wait for tonight.

As the movie neared its end, Todoroki was already looking tired. Damn Deku always woke Katsuki up for sex, waiting till Todoroki first went to sleep. Luckily Katsuki didn't mind the few extra hours up if it meant he could fuck Deku into the mattress.

When the movie ended, Todoroki was dozing off and Deku looked annoyed at the fact. Katsuki smirked as he stood up, knowing he was getting action tonight.

As expected Izuku knocked on his door half an hour later, barging into his room to wrap himself around the boy and kiss at

his neck.

"Your sex drive is unsatisfiable." Katsuki snickered, grabbing Izuku's ass with both hands. Izuku hopped onto his waist, pulling his face up to kiss at Katsuki's lips.

"It's hard when you'll the only one who can satisfy me." Izuku mumbled between kisses.

"Your pretty

little boyfriend isn't good enough for you?" Katsuki purred. Izuku pouted, "I like him. He's just..."

"Vanilla, I know." Katsuki rolled his eyes. But why should he care anyway? He was getting action and Todoroki could hardly be considered his friend.

"He did surprise me tonight

though." Izuku hummed, getting out of Kacchan's grasp. He pulled his shirt off, followed by his pants to show off the cute set Todoroki had given him.

"Damn." Katsuki whistled as he looked Izuki up and down. The boy gave him a twirl, smiling shyly with pink dusted cheeks.

"Too bad Icyhot missed this." Katsuki grinned, fully planning to eat Deku up tonight.

"He'll see it eventually, he did buy it." Izuku shrugged, then walked back towards Kacchan, "But let's stop talking about him."

Katsuki purred, grabbing Izuku's waist and pulling him in for a

deep kiss that Izuku melted into.

"Lay down for me." Katsuki whispered, guiding them to his bed. Izuku laid down, biting his lip happily as he spread his legs for Katsuki to crawl between.

He grabbed Izuku's panties, pulling them down his hips.

"Funny how your boyfriend

got these for you yet I'm the one ripping them off." Katsuki whispered, red eyes glancing up to Izuku.

"Kacchan..!" Izuku whined, hips jerking up.

Katsuki removed the panties then went back down, grabbing and spreading Izuku's cheeks.

He ran his tongue over the quivering hole

rimming him teasingly slow.

"Ahh, Kacchan!" Izuku moaned, grabbing his hair. He pushed on the blonds locks, wanting more.

Katsuki pushed his tongue in, fucking his hole roughly to make Izuku scream.

Izuku gasped and groaned, pulling and shoving on Katsuki's hair. Katsuki moved

up, chin covered in his own saliva, "Am I better than your boyfriend?"

"Yes!" Izuku whined, back arching, "Please fuck me, Kacchan. You do it so much better than Todoroki."

"That's a good boy." Katsuki purred, grabbing the lube from it's usual spot. He poured some onto his cock

before lining it with Izuku's hole and pushing in.

"Kacchan-" Izuku whined, feeling Kacchan's cock sink into him.

Katsuki steadied himself over Izuku before he began thrusting, rocking his hips hard the way he knew Deku liked it. The boy was soon clinging onto him, nails

running down his back leaving behind red marks.

"Kacchan, Kacchan, Kacchan!" Izuku gasped out, hardly able to form any other words. It wasn't long before Deku came onto himself, cum spilling on his top and stomach. Katsuki pulled out, cumming more onto the lingerie as if marking

it for Todoroki to spot later.

As the boys calmed down from their orgasums, Izuku got up to clean himself off.

"Heading back to your boyfriend?" Katsuki asked, sinking into his bed. Izuku nodded.

"Yeah. Thanks."

Katsuki rolled his eyes, "Just break up with him already."

Izuki sighed and looked back at the blond.

"I like him, Kacchan. I already told you that. And he loves me a lot."

Katsuki huffed and rolled onto his side.

"Whatever, just don't get yourself caught."
