(Part II, Can be read by itself)

Katsuki becomes particularly rough when his sweet younger brother is actually close to having a boyfriend. He'd read into all the signs.

Izuku would constantly

have his phone by his side, eagerly shaking in his seat before the screen lights up. With a bright smile, he'd read the message from the unknown extra and happily type back while humming.

He also takes a little longer to prepare before he gets dropped off to college. Choosing

the skimpiest thing he could wear that would still fall under their university's dress code. Meaning he'd be in tight shirts and ass shaping jeans most days. Even taking the time to put on light makeup and applying the sweetest perfume Katsuki has ever smelt.

If it weren't for

the fact that Izuku was a consistent deans lister and A+ student, the older male would have probably fucked him seven ways to Sunday and have him miss all of his stupid classes.

But that wasn't the worst sign. No. It was when Katsuki checks up on him in the middle of the night

and his little brother is wide awake.

He'd open the door just the slightest bit and observe his precious bunny, lower half completely exposed while eagerly humping his favourite pillow.

The greenette would stuff his own mouth with one of his lacy underwears to keep himself

from making a sound, riding fast until he violently shakes from the stimulation on his front and the waves of pleasure from the thick dildo shoved up against his sweet spot.

Katsuki would listen to the pitiful whines and pants from Izuku, ready to give him a helping hand when

he heard something that made him freeze.

"You did good, angel," says a husky voice. Picking up his phone with his sticky hands, the greenette would make a show of displaying his spent body, biting his lip in excitement when he heard the other male groan.

Katsuki remembers how

he had almost broke the doorknob that night, startling Izuku who accidentally drops the call with this /friend/.

The exposed male quickly gathers his duvet around him, hoping that his brother wouldn't have an idea of what he had been up to until that point.

This irritates the

blonde more.

Clicking his tongue, he'd turn on his heels and make a show of trudging towards the door and shutting Izuku's lights.

"Go to sleep, dumbass."

He was strangely calm. Reaching for the pitcher of water before pouring a glass for himself and downing it in one go.

And then the next minute there's the resounding sound of glass breaking, shattering against the pristine white walls.

No one came to see the damage since their parents were out on a weekly trip.

And Izuku? Well, he was scared. He has put two and two together and concluded that

his older brother probably had an idea. Hell, he could have been there the whole time.

So, yeah, he was scared. But as much as he wanted to provide comfort to the blonde, he knew that this was fair game.

They have never talked about the elephant in the room, and every time

Izuku tried to initiate the talk, he'd get shrugged off. He figured that his step brother probably wanted Izuku all for himself but when he brought over some brunette bimbo one day, the greenette felt weirdly hurt.

/Guess that's not the case after all/

After that, he started to

seek something more serious. A connection that could make him forget about taboo relations, blonde hair and carmine eyes. Or maybe even a worthwhile distraction that could satiate both his physical and admittedly emotional needs.

It was a difficult feat, considering Katsuki was

perfection embodied. But then came Todoroki Touya.

The very definition of tall and handsome, the twenty eight year old male was a successful biochemist. In fact Izuku had met him when he had a lecture in their university and the younger male had been fingering himself to the

thought of tattooed skin and bright turquoise eyes ever since.

Despite that, he still couldn't help but compare the man to Kacchan. They were just so similar, with the air of smugness in their very being and the crassness with the way they talk. And the way they fuck, holy shit

The first night when the guess speaker had Izuku sprawled on a hotel bed, Izuku had to open his eyes from time to time or else he would have accidentally let out a "Kacchan!"

Safe to say, the older Todoroki had become a part of his nightly trysts. He had never wanted to go

beyond fuck friends before this, but lately Izuku had been successful in making the other open up a little more.

When Touya finally asked him out on a date, Izuku was over the moon. This could finally be it. He might finally get into his first ever relationship at the age of

twenty-one. He was so distracted with the possibility of finally getting a lover that he had forgotten the logistics of how he'd go there.

Once he remembers, he'd realize how thoroughly fucked he was.

Again. #bkdk, #dubcon, really jealous big bro Katsuki!

✂️✂️✂️

Izuku hates how coddled and sheltered he had been.

Despite being the top student of their year, he had no idea when it came to public transit. Always being picked up and dropped off by either their driver or, more often, his overprotective brother.

When he had proposed to get

his own license, he was surprised that his father had changed his mind about allowing him to go for it.

Little did he know that Katsuki actually talked to Mitsuki, telling her that driving Izuku was the only bonding activity they have as a blended family. And that he didn't

want that to be taken away. Thus, he is stuck in this familiar predicament.

As usual, Katsuki had been there when Izuku asked his dad if he could be driven to the meeting place he had discussed with Touya.

Tough luck that the driver was currently out sick so he had no choice.

Still the same old, but there's a slight difference. And it was the fact that Katsuki was positively livid.

The greenette felt it from the way the older male's tight grip roughly pulled him towards their garage, hold insistent and bruising. Could see it from the slight furrow in

his brows and the noticeable clench of his jaw.

Kacchan was angry.

Izuku was frozen in his seat when his brother rested his hand behind the younger's headrest while backing up from their spacious driveway and instantly speeding past trees and buildings.

He remained quiet until

his brother veered off into the wrong direction.

"My date is that wa-"

"Continue that and I'll crash the car," Katsuki spoke calmly, knuckles turning white on the steering wheel.

That shut Izuku up effectively. All he could do was shakily send a text to Touya.

/I'll be late/
