I've been thinking about this again today and about Kiri checking with their friends and inviting them over while Bakugou is his foot rest. He's not naked or anything but Kiri makes sure they understand its sexual for them. They all agree, fascinated by the idea that they'll gett https://twitter.com/Sheila_thetank/status/1275520289867259904

To see Bakugou be submissive. He isn't allowed to look at them and he's certainly not allowed to speak to them but Bakugou is hyperaware of them. He's been hard all day long in anticipation for it and now that they're all in their living room, Bakugou can barely hold it together.

Kirishima can apparently tell because after awhile of ignoring him with his feet kicked up, he gives an order.
One second he's laughing at some story Mina's telling about work and the next he's got his hand in Bakugou's hair, yanking him up to look at him.

"Stop fucking moving"

Everyone freezes. Until then no one had acknowledged Bakugou at all (under Kirishima's strict orders) but now, Bakugou can feel their eyes on him like a brand.

Kirishima sits back like nothing happened. "Sorry, piece of shit foot rest wiggles sometimes. Hey Kami, how was your

date the other night?"

Kaminari hesitates but soon everyone is distracted again.

Bakugou focuses on taking deep breaths without moving. He's still except for his cock, throbbing and twitching in his underwear. He was sure he was going to cum when Kiri grabbed him and the

thought of cumming in his shorts in front of everyone only made his situation worse.

He's good for a long time. Kiri even reaches down and pats his head exactly twice, once every thirty minutes. Soon after the second pat though, his knees start to really ache. He thinks about

using his color but for some reason that feels more shameful in front of their friends than anything else they're doing. He starts subtly leaning on one knee, then the other, alternating and giving each side a turn to rest. His heart races, imagining what Kiri will do if he's

caught but, he's fine. He shifts his weight back and forth and falls back into a calm head space but it's a mistake. It's time to switch to his right side but he leans too far. His body must be more sore than he thought because to his absolute horror he tumbles to the floor.

Sero stops talking mid sentence and Mina gasps out loud. Bakugou doesn't need to look at his master to know he's pissed. He keeps his eyes downcast, still laying on the floor.

"Get the fuck up, foot rest." Kiri growls out.

"I can't"

"Can't or won't?"

Bakugou whimpers, "I...

I can't."

Kirishima immediately slides onto his knees and cradles Bakugou's face in his hands. He can't hide the concern in his eyes.

"Tell me what's wrong?"

Bakugou's face is burning.

" 'm just sore, that's all.."

He lays still while Kiri looks over him, eyes critical.

After a minute he seems to be done his inspection and grabs Bakugou by the chin.

"Tell me if I'm understanding. You pushed yourself past your limit and let your body get so sore that you fell over? And you didn't use our safe words??"

Shamefully, Bakugou nods. Kiri moves away

so quickly he almost regrets his honesty.

Kiri stands over him.

"Katsuki, you know better. We worked so long on using your safe words when needed. Safe wording out isn't /weak/, it's the only way for me to trust doing these things to you. I have to trust that you know your

limits and that you'll tell me when you need to stop or take a break. I'm so disappointed."

Shame fills his stomach like lead as Bakugou struggles to sit up. He bows his head, too afraid that he'll start crying if he looks up.

Kirishima continues.

"You need to be punished."

He sits back down on the couch and addresses their friends.

"Guys you are welcome to stay, honestly, Katsuki deserves to be humiliated over this, but! I totally understand if you're not comfortable. Often, Katsuki's punishments end in him, me or both of us cumming. I get it if

you don't wanna stick around for it!"

The casual way that Kiri's discussing punishing him has Katsuki trembling. Seeing Kiri switch back and forth between dominant master and his usual sunshine self is a rare sight but it never fails to turn him on.

Their words don't register

but Bakugou understands that their friends all respond positively to staying around and watching. He doesn't know if he's excited or dreading his punishment. The dueling emotions only feed his arousal.

Kirishima turns his attention back on Bakugou.

"Can you move now?"

He nods.

"Can you actually or are you lying again?"

His voice cracks as he forces himself to speak, "No sir, I can move."

Kiri smirks, "I'm glad you still remember your manners. Maybe you're not such a disappointment afterall."

Bakugou hates how his stomach swoops at the backhanded

compliment.

Kirishima pats his empty lap.

"We'll see though. Come here."

Bakugou doesn't need further instruction. He lays across Kiri's thighs and grips the edge of the couch cushion. He makes the mistake of looking up and sees Sero, Mina and Kami watching with varying

degrees of amazement and interest. He drops his head and buries it in his arms.

Kirishima only gives him a moment before he's yanking his pants down over his ass to his thighs.

"I'm going to hit you ten times, Katsuki," Kiri announces. "Don't worry about counting them, you'll

be answering some questions instead."

At the end of his sentence he brings his hand down across both of Bakugou's cheeks.

"Do you understand?"

His response is automatic.

"Yes sir!"

Kirishima hums and squeezes his ass gently. Then he's pulling back and spanking him again.

"Is it weak to use your safe words, Katsuki?"

"No sir!"

Kiri moves his hand and smacks him lower, brushing the back of his balls as he slams down.

Bakugou keens, arching his back and gasping for air.

"Why didn't you use a safe word when you needed to?"

He expected this

question but it's no less embarrassing. He knows his entire body is flushed and he hopes his friends assume is from arousal and not shame.

"B-because I wanted to prove that I could handle it! I don't want our friends to think I'm weak!"

For a moment, he's sure he hears Mina

begin to talk but she's quickly cut off by Kirishima.

"Good boy. Thank you for your honesty."

Kirishima reaches between his legs and grabs Bakugou's testicle, squeezing and gently rolling them in his hand. Bakugou spreads his legs to unconsciously give him more space but it's

over quickly. He thrusts his hips into Kirishima's thick, hard thigh and his eyes roll back at the pleasure that zips through him.

Kirishima spanks again, twice. Leaving a stinking welt on each side of Bakugou's ass.

He laughs, "You can cum whenever you'd like but I'm finishing

your punishment no matter what. Bad boys who don't listen and aren't safe need to be punished, Katsuki. Isn't that right?"

He hits him again. Bakugou cries out in pain but manages to nod.

"I didn't hear you. What did you learn today?"

Kirishima's next spank starts as white

hot pain but it melts into tingling pleasure. He moans out loud and is shocked when he hears and answering groan from across the room.

He's gasping, out of breath from the overwhelming amount of sensations but answers his master's question.

"I learned! I learned that I'm bad!

And I need to be honest!"

He yells out his sentence as he's spanked again and quickly rambles out the rest.
"And it's not weak to use my safe words, I promise I won't forget again!"

Kirishima grabs him by the hair and forces him to arch back harshly.

He growls into his ear.

"Very good boy, Katsuki."

Bakugou shivers, arousal bubbling and growing as he continues to rut into Kirishima's thighs.

The last two hits are the hardest yet and they send Bakugou over the edge. He thrusts his hips frantically as he cums into Kiri's lap, eyes crossing with

the intensity.

He goes boneless in the aftermath.

Kirishima pets his head and murmurs praises. Kami is the first to speak up.

"That was so fucking hot guys."

Kirishima chuckles.

"Thanks for helping us out today. I'll text you later to unpack some of that but I need to take

care of Katsuki. We'll see you later, yeah?"

"Yeah that's fine dude" Sero says, "thanks for including us."

The boys get up to leave but Mina comes over and kneels by Bakugou's head.

"You're the strongest person we know."

She kisses his forehead, then Kirishima's and leaves

too.

Bakugou can't help but smile as Kirishima carries him to the bath.
