eijirou’s biggest secret does not pertain to his past, or his family, or his quirk.

eijirou’s biggest secret is that denki has a bony butt.

and that said bony butt does hurt a bit after an extended amount of time on eijirou’s lap.

eijirou has never complained because he loves having denki in his lap too much to risk losing it.

he loves wrapping his arms around denki’s warm waist; loves the ensuing giggle that seems to reverberate through denki’s entire body.

loves resting his forehead on denki’s back, feeling the rise and fall as denki breathes; loves the easy intimacy, the way denki interlaces their fingers together and plays with their joined hands as he converses with a classmate.

what’s a few small twinges of pain for heaven?

one saturday in the common room, mina playfully invites denki to sit on her lap as they watch a show. “gonna make kiri jealous,” mina wiggles her eyebrows, causing denki to laugh and eijirou to pout.

after ten minutes, she complains.

“kami,” she whines. “your butt is so bony! it hurts!”

denki gasps. “no, it isn’t!” he frowns. “ei‘s never complained!”

“because he loves you too much to,” mina rolls her eyes. “kiri. is denki’s butt bony or not?”

“tell her, babe!” denki encourages.

for the first time in his life, eijirou thinks it is unfortunate he doesn’t have a lying bone in his body.

“it... is,” eijirou winces. “I’m sorry! I didn’t wanna say anything! i-it’s not a big deal!”

denki furrows his brow, hurt.

“fine, then,” he says. he leaves mina’s lap to sit properly on the couch, sullen.

mina makes her escape a few minutes later as the credits roll.

eijirou powers the television off and turns to face denki, whose gaze purposefully avoids eijirou’s.

“denki, I’m sorry.”

denki shakes his head, finally looking up. “why didn’t you tell me I was hurting you?” he sulks. “you already do so much for me—the least I could do is not hurt you...”

eijirou’s heart stutters. “because mina is right,” he rushes to say, hand darting out to grasp denki’s.

“because I love you too much,” eijirou says. “I love being close to you, denki.”

denki looks about ready to burst into tears. “still!” he cries. “I don’t want you to be uncomfortable! that’s not fair!”

“denki,” eijirou pleads. “I really don’t mind. I love it, okay? I swear.”

denki sniffs. he inches closer to press his side to eijirou’s, nuzzling his shoulder. “fine. I won’t stop. but you need to tell me when it hurts, okay? promise? there are other ways to be close.”

“eh,” eijirou begins to protest.

“promise,” denki repeats sternly.

eijirou sighs fondly. “okay, fine. I promise.” he leans down to peck the tip of denki’s nose. “you’re taking this really seriously, babe.”

“because I love you too much,” denki parrots.

he tightens his grip on eijirou’s hand before dropping a kiss on the back of eijirou’s palm. “thank you, ei,” he smiles.

eijirou grins and presses a long kiss to denki’s temple.

as promised, eijirou taps denki’s hip lightly whenever his thighs need a small break. denki then shifts to the couch, slinging his legs over eijirou’s lap instead, or simply snuggling against his side.

these cuddling positions never last long, because eijirou hauls him back to sit properly on his lap after only a few minutes.

denki giggles and supposes there’s nothing he can do about that

( mina apologizes later, of course, which both denki and eijirou accept with a smile.

“we’re all good, mina!” they say, denki perched firmly on eijirou’s lap once more.

“I can see that,” mina laughs, relieved. )
