You and Megumi had always been very close, even though you two are the same age; he always scolded you/bossed you around ever since you two were able to talk. Maybe it was because Gojo never really was the model caretaker, so Megumi had to step in to correct you at times.
He never really had any girlfriends, girls were always either too scared/nervous to approach him, or you would scare them off first. Sure- you guys are brother and sister, although recently you have noticed the occasional dent in his uniform while doing training sessions together and how he's been avoiding you for a few months now

"Hey Megumi! Gojo says he needs you for somethin-"

You were cut off, seeing the scene of Megumi with his hand underneath a blanket and his phone propped up with his other.
You could kind of imagine what he was doing; he's a teenage boy, and you're not stupid.
Megumi's face flushed before yelling,

"Just tell him I'm busy; now get out!"
He said in a stern and shaky, embarrassed voice

You chuckled to yourself before responding,

"Busy with what? It doesn't look like you're doing anything important to me."
You decided to entertain this whole situation; after all, you were bored anyway, and it's fun seeing the guy who has bossed you around most of your life in such a vulnerable and embarrassed state.

His eyes narrowed and his jaw tightened at your teasing.

"Fuck you,"

He muttered, adjusting his blanket, clearly attempting to hide his obvious bulge.

Smirking at the sight, you lean on his doorway, waiting for him to stand up.

"Come on, get up already; it seemed pretty urgent."

He ran his hand through his hair in frustration.
"Fine,"

He sighed, then dropped his voice to a whisper.

"Wait outside for a minute, would you?

You take a step into his room and shut the door behind you

"What's really stopping you from getting up right now, hmm?"

Megumi's eyes darted to the blanket covering his lap, then back to you, his mind racing with ways to stall.

"You always have to make things difficult, don't you.."
He growled, clearly getting fed up with you poking fun at him

"y'know what? I'm just gonna make you get up myself, you're being so weird."

He tensed as you said that, his body preparing to guard his lap from your view. As you approached, he quickly crossed his arms over his lap along with the blanket, trying to hide the evident bulge underneath.

You smiled at the sight of the "Cool Cold Guy" look wearing off and turning into panic.
Despite his efforts at hiding it, now up close it was even more painfully obvious just how worked up he was
"Aww, look at how pent up you are!"
You teased as you swiftly pulled the blanket off
"You could've just asked me for help, I wouldn't turn down my brother"
Smirking at him slyly before reaching down to stroke him slowly

Megumi's eyes widen in surprise, a mix of pleasure and conflict showing on his face as you start rubbing his dick passionately.

He Let's out a sharp gasp, his entire body tensing at your touch. His hands automatically go to try and grip your wrists, but instead of stopping you, they just hover, uncertain.

"What... what are you doing? Stop..wait- please"
he whispers, his voice thick with desire, his breath becoming heavier.

"It's okay.. you don't have to go through the rest of the day like this, let me help you"

His voice comes out rough, barely a whisper. "Oh God please... Stop- This is really fucking wrong, you know that..we shouldn't be doing this"
He lets out a low moan as you continue stroking him.

Ignoring his pleas, you go down on him, looking up at him to instill more embarrassment as you slowly wrap your tongue around his tip, that is already leaking small bits of pre-cum
He gasps loudly, one hand flying to the back of your head, holding you firmly. "Mmm!..Shit..You really need to stop..."
His words trail off into another moan as you take him deeper.
"You're... you're gonna make me..."
Hearing the moans coming from his mouth, you warmly begin lapping up and down his whole shaft
He throws his head back, his body constricting as you take him deeper "Dammit... you can't... you can't be good at this...if you keep this up,"
He pants, his hips bucking slightly.
"You're gonna make me finish too fast..."

Slobbering up and down his cock, you can hear the slight whimpers reluctantly leaving his mouth, with him clearly trying to maintain some semblance of control but failing miserably
" I'm gonna come... stop..."
His breath hitches
"I don't... I don't want to come in your mouth..."

You start to quicken your pace, desperate for Megumi to finally give in and break

He lets out a muffled groan, tightening up as he gets closer to the edge.

"Dammit.. You have to stop..- You can't...
His words dissolve into incoherent mumbling as he reaches the point of no return.
Megumi's fingers tighten in your hair as his inevitable orgasm hits, a strangled moan escaping his lips.
"Oh fuck... oh fuck..."
Releasing a hot load completely and deep down your throat.

You lift your head up from his softening cock as you struggle to swallow his seed

"Oh wow Gumi! You came so much! you've really been holding that in huh?"

He pants heavily, his body relaxing as he comes down from the intense release.

"Shut up..."
He mumbled, his face flushed and his eyes glazed over.

"You shouldn't be talking about it... This situation is already embarrassing enough.."

As he pulled his boxers back up, you two settled in bed; without any warning, Gojo barged into the room

"Hey you two! Want to try some of these new souvenirs I got? I Swear these are the most delicious ones yet!"

You look at Gojo and then smile

"No thanks! I'm already full!"
