Their Hot Romance (BakuDeku)

Chapter Seven

Katsuki woke up with a sharp pain in his lower abdomen. He whimpered and whined as he slowly sat up. He froze once his feet were on the ground. The feeling of his soaking wet boxers made him close his eyes and sigh.

Three days early, huh? That's pretty normal. He thought to himself as he got up. He grabbed arm fulls of blankets from his closet then got started on the nest he usually kept in the walk-in closet. It was a precaution, so that nobody ever found his nest. Having not lived in his apartment long, he hadn't gotten the chance to make his nest.

It took him close to an hour, but he got it done. The sound of his alarm ringing had him sprinting into the bedroom to turn it off. He shot Best Jeanist a text, saying he wouldn't make it into work. He also shot Denki a text, asking if he could come take Ryuu outside in the mornings and the afternoon since Katsuki wouldn't be able to. After getting replies from both, he returned to his extremely warm, comfortable nest. He stripped down to nothing then got comfortable inside.

Katsuki fell back asleep to prepare energy for his first wave.

Upon waking the second time, he was covered in sweat and slick. He whimpered softly as he rotated. The pain in his gut was almost too much for him to move. He reached helplessly for the box of sex toys that sat on the floor in the back of his closet. With a desperate whine--as if that would convince the box to grow legs and walk to him--he continued to reach. He slowly inched his way towards the box until he could grab the end. He knocked it over then all of the toys just fell out. Katsuki grabbed the first dildo that he saw then placed it next to him.

He slowly pushed a finger into his aching hole. He grimaced at the feeling of his own slick. He added a second finger then started to scissor himself open. He whimpered and whined as he fucked himself open. He quickly added a third finger then a fourth. Once he felt like he was ready, he pulled his fingers out. He wiped them on the blankets before grabbing his dildo. With six years of practiced ease, he pushed the head of the toy into his aching cunt.

A loud moan escaped his lips at the feeling of the toy filling him up to his fullest. His body shivered as his toes curled. His back arched up, and his mouth was wide open. He pushed the toy in until it was at the base of the fake balls. He let it settle for a moment before moving it in and out of his aching body.

Day two was the worst of them all. Katsuki's mind was gone to the heat in his body, begging for pups that a fucking sex toy couldn't give him. Katsuki fucked himself hard on the knotting dildo, pounding it into him with as much force as he could muster.

"Den!" He hollered when he heard his front door open. The golden haired omega had come to take Ryuu to use the bathroom. "Denki!" He whined. He heard quick footsteps then Denki appeared in the open doorway. The other omega didn't flush in the slightest at Katsuki's naked body, the dildo sticking out of his ass, or the desperate whimpers leaving his lips.

"Whatcha need, Blasti?" Denki asked him. Katsuki held up his legs.

"Not fast enough." He told him. Denki nodded his head. He walked forward then knelt down before him. Katsuki's hypersensitive body felt the other omega grab the toy then start ramming it into him. Denki angled it just right so that it hit his prostate. The ash blonde male moaned wildly with every hit.

"I'm gonna fuck you full, alright?" Denki whispered to him. "You're going to be leaking on this knot for weeks."

"De-" Katsuki tried to force out.

"That's it. Call out to me, Katsuki." Denki encouraged. Katsuki growled violently at the use of his first name, which confused the straw blonde. "Call out to me. Call my name."

"Harder, Deku!" Katsuki's heat-fogged brain called out. Denki's eyes widened with realization. He pumped the toy into him faster.

"You're so good, Kacchan." He whispered. Katsuki didn't growl that time. "So tight around my cock, Kacchan. So good for me, Kacchan." Everything he said had to have the childhood nickname attached. If he called the writhing omega anything else, he'd likely be greeted with a feral attitude. "Come for me, Kacchan." Katsuki came with his words. Denki pressed the button on the dildo then pushed the dildo in as far as it would go just in time for the knot to pop. "There you go, Kacchan."

"De-Denki... sorry." Katsuki whispered after a few minutes. He was coming down from his heat fever for the first time in hours, having finally gotten the knot he'd been trying for.

"Hey, don't mention it, man. You remember my first heat at school, right?" Denki inquired with a grin. Kstsuki weakly nodded.

"Everyone else was too fucking chicken to go anywhere near you. They just wanted to leave you there on the gym floor." Katsuki recalled. "Fucking Eijirou was going mad from your scent, and you kept calling out to him. Not even Round Face or Sparkles would go near you."

"Then you manned up and scooped me into your arms. Damn, Katsuki. If I didn't have Eijirou on my mind, I probably would've fallen for you. You took me to Recovery Girl, and she gave us a private room. She gave us some knotting dildos that she had lying around, which I vaguely remember you demanding because you refused to fuck me yourself. You helped me for hours. You put up with my callings for an alpha I barely knew, but wanted so bad. You put up with me until I came down from my high -- kinda like you are right now -- and then got my permission to call Eijirou. I think that was one of the first moments where you started to tolerate me. Though I was fully expecting you to put me down, rail me, stuff me full with your knot, and make me your bitch before anyone else had the chance."

"I think everyone did." Katsuki mused softly.

"Yeah. You gained a lot of respect among the other alphas in our class. Though they're really just easily deceived." Denki joked, making Katsuki chuckle as well.

"Hey, could you stay for a bit?" Katsuki asked him.

"Totally, man. Just let me take Ryuu out then I'll text Eijirou to tell him I won't be home for a bit. Actually, I can ask him to bring some clothes if that would help. Sound good?" Denki inquired. Katsuki shook his head with a soft growl.

"The only fucking alpha scent I can even think about it fucking Deku's. Anything else might send me into shock or something." Katsuki admitted with a sigh. Denki nodded in understanding. He placed a tender, familial kiss to Katsuki's sweat-covered forehead, then went to do as he'd said he would.

Katsuki's heat surprisingly ended on the third day. Normally, they lasted around five days before an omega could come out of it. But apparently Katsuki's decided to end quickly.

He rode out the last few orgasms on his own seeing as Denki had left late the previous night. Ryuu came in with a bottle of water gently sitting between his teeth. Katsuki thanked him after taking it, petting his head to show his appreciation for the canine.

Katsuki's memory of the previous day was relatively fuzzy, but he could remember the amount of times Denki got him to call out the horrible nickname he'd given his childhood friend. For a bit, he was sure he was convinced that it was Izuku speaking in his ear.

Katsuki knew Denki would probably only tell Eijirou, but the thought of more people finding out was frightening.

Katsuki let it go though. He rested back into the nest after he'd finished the bottle of water, and let himself go to sleep.
