It was Friday night after school and both of Deku's Alpha's went out to go get some snacks and stuff. He was feeling tired from training too hard and decided to stay in the dorms and sleep while they were out. On the way back home Tetsu almost hit Kirishima with the milk jug because of another argument over who was harder, (Wink) which caused Kiri to stumble and drop the shopping bag with pocky. "God damnit Tetsu." 

Kiri smiled at the thought of how many arguments they had over this. He bent down and picked up the pocky boxes that were strewn across the sidewalk. "You're lucky none of them spilled because you'd be the one explaining to Deku why he isn't getting his poc-What the fuck?!" The redhead whipped around to see his boyfriend who had just smacked his ass, looking down at him with a grin. "Yeah well they didn't so let's get home to our Baby Boy." Tetsu smirked. Kiri finished putting the pocky boxes back in the shopping bag and held his boyfriend's hand on the way back home. 

~Time Skip~

The two Alpha's arrived back at the dorms safe and slammed the door loudly considering everybody else went out and got some extra training in. Once the boys put their stuff away, Kirishima sniffed the air. "Hey Tetsu, you smell that?" Tetsu sniffed the air as well and smelled the sweet sugary scent of their Omega, "Mhm, Izuku's probably jacking off." Tetsu chuckled. The redhead sniffed the air again and listened. I don't hear any moaning and this smells different..." Kirishima looked at his boyfriend. "Oh shit." They both said. 

See, since Deku was an Omega, he had heats. Just like both of his Alpha's have ruts. (If you don't know the omegaverse then you can look at the first chapter of my other story "How To Be A Disappointment" explaining how these work.) And he had only had one heat before and it was weak because he was on a low dose of suppressants. So he's technically never had an actual heat. Both Alpha's raced to Deku's room and knocked on the door. 

"Izu baby you ok in there?" Tetsu pressed his ear against the door, "Can we come in?" Kirishima asked. They heard soft panting before an answer, "Ngh..Y-yeah.." Both boys walked in and Tetsu locked the door behind him. They were hit with a strong wave of pheromones that made their faces flush pink.

Their Omega was curled up on his bed groaning in pain. Kiri walked over and stroked his Omega's green curls, "Baby we're so sorry, you said it wouldn't come for another week." Deku curled up tighter and breathed heavily, "I-I know....It came early..." Tetsu walked up to his boyfriends and sat on the greenette's bed. 

"Can we help?" He asked. Deku looked up at them with glossy eyes, pupils big from lust, "Yes, please...Please do." Kirishima smiled sweetly at him before getting up and pulling Tetsu with him. Deku whined from not having both of his Alpha's touch on him. "What's my name." The redhead asked while he and Tetsu got undressed down to their boxers. 

"Ngh, p-please touch me again.." The redhead walked over again and pulled Deku's green hair back, exposing his neck. "Let me say this again." He leaned down and got close to his neck, ghosting his lips across the sensitive skin. "What is my name." Deku squeezed his eyes shut. He was loving this. 

"D-Daddy...Y-Your name is Daddy." 

Kirishima smiled and praised him. "Good boy." He said as he rolled the smaller boy on his back and straddled him. Deku was already in his boxers so Tetsu kneeled by the bed and started playing with his nipples. "A-Ah fuck." He groaned. Kirishima started grinding his clothed erection against the smaller boy's and choking him. Deku reached up and pulled the redhead down to kiss him. 

They break apart when Tetsu bites Deku's nipple, making him almost gasp but having it come out as a strangled noise from the hand around his neck. Deku tapped Kiri's arm twice and Kiri immediately let go. "Sorry Baby Boy, was that too much?" Deku panted lightly, "No, j-just needed a breath." Kiri nodded and continued by kissing and sucking on Deku's neck, making the boy underneath him breathe heavier.

 He kept going down until he was at the nipple Tetsu wasn't sucking on. He latched his lips around it and bit down lightly. "F-Fuck! Daddy!" The redhead continued while Deku pulled his other boyfriend up to kiss him. Kirishima stopped toying with his boyfriends chest and slowly ran his nails down Deku's sides, making him shudder from pleasure. Tetsu pulled away from the kiss and went down to slap both of the smaller boy's thighs, "Oh shit!" He moaned out. His Alpha's loved his moans, they didn't sound girly like other male omega's. They sounded like normal male moans, that's what his boyfriends wanted. They were gay for a reason, they didn't like girly moans.

Kirishima yanked Deku's boxers off and threw them somewhere in the room. Deku took in a sharp intake of breath as the air hit his hot skin. Tetsu took off the redhead's boxers as well as his own and started making out with him. Deku watched as he slowly trailed his hands down to his erection. Kirishima looked over and lightly slapped his hand away. "Let me do that," He stroked his Omega's erection agonizingly slow, making the Omega groan lowly. "Ngh-Fuck-Please!" Kirishima smiled and went even slower, almost stopping. 

"Beg for it if you really want it Izuku." 

Deku's hands went to his curly hair as he begged, "Please, oh god please Daddy. Please touch me and make me yours. I want my Alpha's to make me scream. Please." Both Alpha's groaned. They loved it when their Omega begged, it went straight to their dicks. Kirishima slammed his hands on either side of his Omega and made out with him. Tetsu bit his lip as he slowly stroked himself to his boyfriends. 

The boys switched positions so Deku was on his hands and knees. Deku started sucking off Tetsu, "Fuck you're good at this." He groaned, tilting his head back in pleasure. Kirishima went to get the lube from the dresser but Deku grabbed his wrist, "I-I'm in heat so you don't n-need it." Kirishima nodded and got back behind his green haired Omega. He stuck two fingers in with ease from the slick. (Slick is like the natural female lubricant but for male Omega's) The smaller boy moaned around his boyfriends dick, causing him to groan. The redhead made a scissoring motion and more of Deku's muffled moans could be heard. After a couple minutes Kiri pulled his fingers out and replaced them with his dick. Deku choked around Tetsu's cock as Kirishima set a fast pace, holding the smaller boy's hips and holding on tightly. "Shit Deku.."

 Deku pulled off Tetsu's dick as he moaned out, "Oh fuck-Kiri!" Tetsu put his hands in his Omega's curly hair and pulled as he went back to sucking his dick. Kirishima started thrusting faster and at a more uneven pace. He leaned forward and started choking Deku and stroking his dick at the same time. Deku moaned loudly, as loudly as one can while sucking dick and being choked, and his eyes squeezed shut as he came. Tetsu came as well from his boyfriend moaning around his dick. After a couple more thrusts Kirishima came in his boyfriend as he groaned loudly, "S-shit!" Kirishima pulled out and let go of his boyfriend, Tetsu pulled out of Deku's mouth as the Omega panted with cum running down his chin. The three boys went and showered together. (Let's say showers in the dorm are big enough for three people to stand comfortably) They went back to bed and cuddled eachother and slept for the rest of the day.
