Katsuki Bakugou is a professional rigger.

Like sometimes when hes stressed he might ask one of the Bakusquad over to his room to help him relax and no one else gets it but them (and Izuku) but they know hes asking them to let him tie them up.

He puts all his stress and anxieties into every carefully tightened knot.

Hes extremely gentle too, making sure he never tries them too tight.

Hes also slow, tanilisingly so, so that he doesnt give them rope burn.

And as a result they often end up aroused.

Rigging always leads to some cuddles too, and both the squad and Katsuki appriciate it.

But Izuku is a little jealous that Katsuki and his squad have this "secret" for themselves and he wants it too.

So one night, Izuku knocks on Katsuki's door with is backpack on and his head low.

He's shaking and visibly stressed.

As much as Bakugou might be an asshole, he wouldnt turn Deku away when hes like this.

So he let's him in and waits for him to speak.

"Kacchan.." gone was his stutter, too anxious and tightly wound to stutter "I need your help... I only trust you to help.."

Katsuki, sat on his bed, gruffly hums and nods for Deku to continue.

Taking his backpack off, Izuku throws it at the blond with a simple "open it".

Inside his back, are several types of cotton bondage rope, 5 metres, 10 metres, black, red, purple, green and orange.

Katsuki looks up to Deku with a brow raised, successfully hiding how shaken he feels at the request.

Deku's face is slightly flushed.

He assumes in embarrassment, but his flush is more out of annoyance. However Katsuki understands how tense he is from his body language and doesnt beat around the Bush.

"You want me to tie you up? Why me you perv?" He states simply, almost like a test and a deterrent.

Breathing in and trying to calm his now freying nerves before he answers.

A pause.

"Because I only trust you to do this..."

Another pause.

"Tsk... fine. But I need your consent." Katsuki all but demanded. He will ALWAYS require verbal consent.

Even with the squad after so many times.

Katsuki needs the consent.

Without even thinking twice, Izuku looked Katsuki in the eyes and responded without hesitation.

"Yes Kacchan, I consent to you being in control."

The extra part wasnt expected from Deku, however...

Now Katsuki understood what Deku needed.

After years of feeling helpless and unless, Izuku being in control is foreign and difficult for him.

He's 'been in control' for too long. The stress has built up.

He needs to go back to how it was.. for a time.

And Katsuki can do that.

So he nodded and walked over to Deku, standing directly in front of him.

"Alright Deku. You'll do exactly as I say. If something is too much, then say 'red'. Its a safe word, to keep you safe."

Deku nodded "Yes Kacchan."

"If I ask 'is this okay?' I want to to respond with either green/amber or red. I shouldnt need to explain why should I?" He continued, carefully guiding Deku to sit on his bed.

"I understand, Kacchan." Izuku nodded, sitting down when guided to do so.

((Ngl didnt plan for this to turn into a thread but I think I'll continue it? Should I?))

Happy with Deku's answer, Katsuki took the rope out from Izuku's bag and even grabbed his own from the drawer under his bed.

Izuku sat patiently as Bakugou prepared the ropes, specifically the black and orange. Call him egotistical but he wanted to see Deku is his colours.

So sue him.

With the ropes layed out on his bed next to where Deku was sat, Katsuki let his eyes roam up and down the freckled boy, contemplating how best to tie him up.

"Take off your shirt Deku."
For a command, Izuku couldn't help seeing it as being gentle. A suggestion.

So he complied, pulling his shirt up over his head where he sat and stood when Katsuki motioned with his fingers to do so.

"Deku... stand in the middle of the room." The blond stated in a hushed, low tone.

All Izuku could do was as he was told.

The flush that has been atop his cheeks when he entered slowly morphing from one of annoyance to excitement.

He was leaving all the control to Katsuki and he didnt have to work his brain anymore.

Its was nice.

He could feel a tiny amount of the stress he built up leak out.

Katsuki was behind him, and he could hear him shuffling with whatever he was doing but didnt look.

Instead he closed his eyes and focused on his breathing.

When Bakugou returned, he was wrapping something soft over his eyes.

"This okay..?" The blond asked, almost unsure.

Though he was caught off guard, Izuku nodded "yes Kacchan."

With that confirmation, the blond began, gently moving Deku's body and limbs where he wanted/needed them.

It was so much easier to tie up Izuku compared to the squad.

Dispite the muscle, he knew this body well.

This was probably the most relaxed he had been while rigging in some time infact.

He could also see as the rope built up around Izuku's body, how the tension was bleeding out.

How his chest was now flushed, how his skin bumped up and his breathes sped up.

Of course all that was the subtle proof of how this was helping Deku, the obvious was the little gasps where he ran the rope a little faster than usual against his skin, and his obvious arousal.

And Bakugou would be lying if he said he wasnt enjoying this as much as Deku was.

"Is this okay, Deku?" Bakugou couldn't help himself how he asked that directly in Deku's ear, low and husky.
He too was highly aroused and...

Yeah the nerd looked great in his colours.

"Yes!" Came Izuku's gasped response, the rope around his ribs a little tight and chafing as+

he breathed in, but just what he needed also.

He could feel his arms, how they were bound using a mermaid tail technique behind his back.

He could feel how his torso was wrapped in a tight tortoise shell down to his knees.

His ass was being cupped by rope and his erection was being exposed through his shorts thanks to how the rope was tied.

But he wasnt ashamed.

He was happy.

Dispite the physical tightness around his chest, he felt like he could breathe easier.

((I'll continue more later maybe, I should eat something))

Carefully, Bakugou picked Izuku up and carried him to his bed, laying the freckled teen down on his back.

Leaning over the blinded and bound Deku was doing things to him and he looked over his bunny. Watching the rise and fall on his chest.

"How do you feel?" He asked tenderly.

Izuku hummed, his tongue feeling heavy in his mouth as he found himself slipping into an almost floating state.

"F's good.." he forced out, tired, almost dopey slur to his words.

Who could blame Katsuki for snorting a little.

In that moment, for the first time in years... he felt like he knew Izuku again, the very same boy he grew up with.

His Deku.

But he had to be responsible. It has only been maybe 15 or 20 minutes since he started tying him up.

Right now, Deku was his bunny.

So he needed to be Deku's rigger and take care of him.
Properly.

"5 more minutes okay." It was supposed to be a question but came out as a statement. "Then the ropes are coming off. I'll have water ready for you."

The whine that left Izuku's throat took him off guard.

"Dun'wanna..." Izuku mumbled, squirming a little only to end up moaning as the rope brushed against his sensitive skin and cock.

"Shh hey... once the ropes are off, we can cuddle okay? Let me take care of you..."

The gentle sound of Katsuki's voice in that moment, and the genuine care it held, broke Izuku's resolve.

Tears wet and rolled down the sides of his blindfold.

"Kay..." Izuku hiccupped, Bakugous eyes widening in concern.

"H-hey is this okay? Deku colour..!" He hurried.

Sniffing, Izuku mumbled green, clear enough for Katsuki to understand.

"Why are you crying..?" He continued, concern clear in his voice.

Biting his lip, Izuku tilted his head to the side, unable to tell if it was towards or away from the blond.

"B... B-ecause K-Kacchan... I love you..." was all he could get out.
And Katsuki needed nothing more.

Because one the words were out, he was quick to press his lips to Izuku's tenderly, like he was pouring emotions he couldn't verbalize into the press of their lips.

When he pulled away, before Deku could ask what happened, Katsuki has spoke.

And all Izuku could do was smile bright through his tears.

"Will you be mine? My bunny?"

"Y-yes Kacchan!"

-End-

((I think this is the first time I have every finished a thread.

And to think, all this came just because I wanted to try and get across why my HC for Katsuki is that he took Shibari courses and became a rigger.))
