MATURE. SEXUAL. 18+
Katsuki didn't have to wait long for things to go wrong. The next day in fact, Izuku's birthday. Katsuki headed to the alphas room after remembering Izuku's words from the carriage ride. He turned eighteen on the 15th and it was the 15th, so he might as well wish him a happy birthday.
It wasn't until he was standing outside of the alphas bedroom that he realized how bad of an idea it was.
It started with the growling, grunting and thudding and struggling. The omega was confused before the scent hit him. Pure lust. It filled his lungs, suffocating him instantly. The two alphas were bonding.
Then that's when the bad stuff happened.
Katsuki felt his knees get weak and he slowly collapsed in front of the door, listening to the noises coming from the room with a whimper. There was alphas in there. The alphas he wanted, and they smelled so good. So fucking good. They wanted him too, right? It seemed like it yesterday.
The noises stopped and so did katsukis thoughts. He suddenly realized where he was and his eyes widened as he started to stand, eyes shooting up as the door in front of him swung open. Izuku stood there, bare chested and pant less, wearing a tight pair of boxers that showed off exactly how excited he was.
Katsuki swallowed and fell on his butt, backing up across the hallway until his back was pressed to the wall. Izuku leaned forward, gripping the doorframe and inhaling deeply, eyes pinned on the omega, so close to him. "Bakugou.." Izuku purred lowly.
"No!" Katsuki said quickly. "Stay in there. Don't come closer!" Izuku growled softly but complied, watching Katsuki with those dark green eyes clouded with want. Shoto appeared over his shoulder, probably wearing less clothes than Izuku. Katsuki caught sight of the second alpha.. area.. as he moved, hugging Izuku's waist earning a warning growl from the greenette. "Come back to bed, Zuku.." Shoto purred softly as his hands traveled over the alphas stomach and hips, eyes trained on Katsuki.
"I'll let you knot me this time." Shoto added, smirking at Katsuki as the omega blushed. Izuku was knotted by Shoto already?! Izuku hummed lowly in content but didn't move, pressing into Shoto's hands a bit as the alpha started to shape him through his boxers.
"Not yet. Katsuki.." Izuku murmured making Shoto huff in his ear, leaning into his mates back. "He's not coming in with us." He reminded, pressing his lips to Izuku's neck. Katsuki watched Izuku tilt his head for the alpha, breath catching as he saw the mating mark displayed proudly, so dark on his pale skin. Katsuki felt very uncomfortable bring the only one wearing any pants. He wanted to change that but he wasn't thinking right now. His omega was clawing to get out, to present for the two alphas and beg for their pups.
The idea was very tempting but Katsuki wasn't one to lose himself so easily. His gaze flicked down to where Shoto's hands were, stroking and cupping and squeezing at the erection hidden inside Izuku's boxers. The alpha was hunched over, dark eyes fixed on Katsuki, hands still gripping the doorframe, lipscparted as he puffed and moaned lowly
"Bakugou, come here, now." Katsuki leaned towards izuku before he jerked, realising that wasn't izuku talking. Yagi stood a few feet away, lighting candles and replacing the ones on either side of Izuku's door. Shoto pulled his mate closer and watched Yagi as he worked, hands still roaming. As soon as they were out of the door way, Yagi pulled the door closed and set up the candles, looking at the omega. "are you alright?" He asked gently.
Katsuki whimpered softly as the scent faded from his nose and he nodded, shaking his head to help clear it, taking deep breaths through his mouth. "Fuck.. I didn't.. think they would be like that."
