Chapter 6 First Step in Becoming A Theta

It had been a week since the UA Entrance Exam, meaning the results would show up within the next week. Two weeks after that would be their high school graduation, with one more month to prepare and get affairs in order before attending school. For those that didn’t pass, the extra month helped students make other arrangements for other schools.

Katsuki had time before Izuku’s rut, to train his body to become a theta. Though from what he read in the pamphlets and guide books becoming a theta is a multi step process. One of the biggest milestones was the first rut, but before that he needed to prepare his ass.

Izuku was huge, even alphas would be jealous of his size, even without his knots. He’s probably break a virgin beta or omega with his meat, and those sub sexes were naturally evolved for taking dick. So for a virgin Alpha like Katsuki it was more than a little intimidating.

He was awoken up early as his morning erection met the bite of his cage. “Grrrr!” Katsuki grumbled. His cock pulsed trying to swell to full length only for the cage to keep him down. “Fuck!” He humped the air, but the cage wasn’t budging.

His hips continued to pump and gyrate, the cage holding his length in a locked state, the tight grip of the device made his penis throb and pulse.

As the alpha looked down at his caged length, it reminded him that he was owned. That Izuku was courting him and wanting to make him his theta. The idea made him ache and shiver, receiving another bite of the cage. ‘Deku…’ It was 4 AM he couldn’t call the nerd and ask for release, he COULD, but he wasn’t going to. ‘Deku...Deku...Deku…’

With the heat of his arousal unable to fill his alpha dick it spread other places. It awakened in his chest first, causing his nipples to get nice and hard. Time would tell when the alpha started feeling it in his ass.

Bakugou got out of bed, getting down on the floor and he started doing push ups, sit ups, and even squats. It was a good effort to burn off the extra sexual frustration he was feeling. Plus it was doing wonders for his body.

He had a lot of sexual frustration to burn, so he worked out for a solid two hours. “Haa...haa...haa…That should do it…” Since he worked up a sweat his pheromones were rising. To think his once prided libido was now working against him.

Bite! Pop!

“Ahhh!” Katsuki arched his back and whimpered, he looked down and his knot was out. “How the fuck...fuck…” His legs felt like jelly and his whole body was shaking with need.

The thick knot was out and the cage seemed ready for it, locking it into place. The knot was something important to alphas and primes, it’s what helped them lock themselves inside their partners to insure breeding, it helped them connect with Betas and Omegas, and some omegas even got off on having the knot pulled out only to be thrust back in again, it was called knot play.

Katsuki remembered reading that Prime’s had multiple knots each one bigger than the one before it. Alphas liked to compare dicks and ball sizes now and then but it was harder to gauge one’s knot size.

It typically formed after an alpha was balls deep inside their partner, maybe halfway through the rut and once it popped out it took hours to calm down. Katsuki clearly wasn’t fucking anyone, and even in masturbation it was near impossible to trigger one’s knot that way, so why…

The cage…

He had gotten horny one to many times, the bites of the cage triggered his knotting instinct inside alphas causing it to pop out.

“Deku...need Deku…” His body was shaking. He didn’t care anymore, he felt like he was going crazy. With trembling hands he managed to grab his phone and dial the greenette’s number.

The phone rang...but no answer…

‘It’s 6 am of course he’s asleep…’ His gaze dropped to his caged dick and locked knot. ‘Heh...my knot’s pretty big huh?’ It was weird seeing it out like this. He hit redial a few times.

Click! “Kacchan?” Midoriya yawned cutely.

“Deku!” Katsuki moaned. Hearing the prime’s voice was doing wonders.

“It’s 6 AM why are you calling so early?” The response was a long and needy whimper. “Oh...ohh...did your knot pop out?”

“Uh huh uh huh!” He felt so hot and bothered, something in his mind told him that if he wasn’t locked up and was hard right now Izuku could make him cum with his voice alone, that’s how horny he felt. “Help...Prime….please…”

“Want me to come over?”

‘YES!’ He bit his lip to keep himself from screaming that. “No...just...keep talking...tell me what to do...let me cum...Prime…” He felt so desperate.

“Status!” Katsuki nearly came, his pupils dilated.

“Green sir…” His voice trembled, having a reverb as it came from both the blonde and his inner alpha. That was a call from a prime that resonated with his body and soul.

Izuku breathed a sigh of relief. “Good boy!” Katsuki let out a lustful moan. “You gonna be good for me?”

“Yes...so good…” His heart was pounding.

“Your knot is all locked up isn’t it?” Katsuki bit his lip and nodded. “Words, use your words.”

“Yes!” He looked down and his precious alpha knot, a piece of his anatomy designed for locking him inside his mated beta or omega, and he was locked...in a cage...Deku’s cage. Pleasure surged through his veins.

“Touch it!”

Touch his knot?

The idea felt naughty, but that’s what his prime wanted. He reached down and touched it. “Ah~ohhhh~!” It was so tender, like the tip of his penis.

“That’s it...feels good doesn’t it?”

“Yes!” He was touching so tenderly, yet the sensation was intense. The bite of the cage grew more pleasurable as he rubbed, he started dripping pre-cum.

“Harder!” Katsuki shuddered and began to rub his knot with his fingers. The alpha was experiencing an erogenous zone most never have touched by fingers. Many alphas would brag about how amazing it was to have their partner squeeze their knot. Here he was doing it with his fingers.

One finger became two, soon he was caressing it with his fingers and thumb. The thumb circled the top while the digits caressed the side. “How does it feel?”

“So hot...want...you…”

“Yeah it would be better if I was there and doing this huh?” Katsuki whimpered.

“Fuck yes!”

“Give it a squeeze.” Katsuki obeyed and….

“Aaaaaaaggggghhhhhhooooooohhhhhhh!” He came, his cage dick squirting and making a mess on the floor. His toes curled and his body trembled. This orgasm topped any he had just jerking off.

“Time for a lesson my sweet little theta, Thetas can be milked in two ways, through anal stimulus via prostate milking, the other is the rarely experienced knot milking. I wanted to be there to see your first time, I bet you look so cute right now.”

Katsuki let out a gurgle. His expression was one of pure delight. “You did so good for me Kacchan, I’m so proud of you!”

“Hnnnnn!” His eyes closed in a dry orgasm.

“If I was there I’d hold you in my arms, and keep milking your knot, making you feel so good.” His voice was doing things to him. The Prime nerd began to talk and talk, going into a warm muttering that lifted Katsuki’s spirit like a cradle, rocking him lovingly. He wanted to hold him, please him, showing him all manner of tenderness and love. “I bet you’re all sleepy now, huh?”

“Nosh Schleepy…” He slurred his words, he could barely keep his eyes open.

“Be a good boy for me, and sleep!” A wave of peace and tranquility washed over the blonde, he was whisked off to dream land. Izuku knew his love was fast asleep hearing his snores. He ended the call.

When Katsuki woke up, he felt so refreshed, after cleaning up his mess, he got a shower and got dressed. He needed to see Izuku. It was early, he dared Inko’s wrath as he knocked on the door.

Midoriya answered the door, his pajamas and hair disheveled. “Kacchan?”

Smooch!

No more words. He wanted to see Izuku so here he was, he wanted to kiss the prime so he was. “Good morning to you too.” His cheeks were burning.

Izuku held his hand and brought him inside. Katsuki felt his cock throbbing in his cage with every step.

Once they reached the bedroom Bakugou yanked off Izuku’s shirt and pushed him onto the bed. Without missing a beat Katsuki buried his face into the Prime’s pit, taking in his manly musk. “Ohhhh~!” He started licking, taste combined with the aroma and made him tremble in delight.

‘Deku...Deku...Deku...Deku...Deku...Deku…’ He thought with every lick.

Izuku let the theta in training play, enjoying his musk and flavor, he was running on new instincts and deep desires. He only moved to get access to the other pit, sniffing and licking to his heart’s content.

‘Prime...Prime...Prime...Prime...Prime…’

When he finished he curled against Midoriya who wrapped his arms around him. The blonde let out a purr of content bliss. It was Izuku’s turn to give Katsuki a sniff and he smiled. His alpha scent was changing, ever so slightly. ‘He’s ready for my rut!’ It was just the first step but it made Midoriya so happy.

To be continued...Midoriya’s Rut
