Giyuu's office door is slightly ajar, giving Sanemi a view of his focused expression. Sanemi bites his lip, torn between wanting to mock and wanting to see more of this caring side. Later at Sanemi's house. Giyuu just arrive to their date. Sanemi answers the door, in casual clothes, his hair messier than usual. He gestures for Giyuu to enter, still having that grumpy demeanor.
"On time. Good. I made dinner."
The house is clean but minimalist, with a few swords on display. The food smells spicy, like Sanemi's personality. He leads to the dining table, sitting across from Giyuu. The air is thick with anticipation.
"So, did Tanjiro survive your lesson?"
"Yes. He understood everything."
Sanemi pours sake, eyeing him over the cup.
"He's a good kid. Not like some people who don't speak enough."
There's a hidden challenge in his words, testing Giyuu's reaction.
"And you find it hot on me when I am acting like that, don't you?"
Sanemi chokes slightly on his drink, taken aback by the bold question.
"W-What? The hell are you talking about?"
His cheeks flush pink, a rare sight. Giyuu remains calm, repeating himself with a slight smirk.
"Tch. Maybe. Maybe I do. Stop analyzing me!"
He shifts in his seat, trying to hide his growing arousal from the question.BGiyuu takes a sip, enjoying the fact he flustered Sanemi. He puts his chopsticks down.
"You're annoying when you get confident."
He moves closer, still defensive but clearly wanting to dominate.
"Remember when I topped you once?"
Sanemi's eyes widen, his body tensing at the memory. He snaps his head up.
"Don't remind me. I let you do that ONCE."
But he secretly wants to relive it, despite his pride. Giyuu leans down, whispering in his ear.
"I think you enjoyed it more than you'll admit."
Sanemi growls, his breathing becoming heavier. The evening went on with fun and moans. The next day Sanemi wakes up first. He is naked, tangled in sheets. He wakes up and sees Giyuu beside him, remembering last night's rough sex.
"Fuck... we didn't use the condom again."
He looks at the trash can, filled with used ones. He groans and sits up, his hair even more wild than before. His back has scratches.
"I'm going to be pissed if you knocked me up."
He jokes darkly, though a hint of concern flashes. Giyuu stirs, waking up too. He wraps an arm around Sanemi's waist.
"Let go. I need to shower."
He's grumpy but not resisting the touch completely. Giyuu kisses his neck, teasingly.
"Ugh, you're insatiable. Work starts in two hours."
He glances at the clock, knowing they'll have to be careful today at school. The alarm goes off. Sanemi gets up and throws a pillow at Giyuu.
"Shut it off and get dressed. We're late."
He limps slightly, trying to hide it. The pillow hits Giyuu's face, and he smiles faintly.
"Don't laugh. I can't limp into class."
He grabs his clothes, muttering.
Genya walks in on them, seeing his brother and Giyuu in the same room. He freezes, mouth agape.
"GENYA! Get out!"
Sanemi grabs a towel, furious at the intrusion. Genya stammers.
"S-Sorry! I forgot my charger."
He spots the mess and pieces it together, his eyes wide with shock.
"OUT NOW!"
He throws another object at him. Giyuu calmly starts getting dressed too, unfazed by Genya's presence. Genya runs away, traumatized indeed, while Sanemi fumes.
"He's never going to let me live this down."
He looks ready to murder Giyuu for not helping him hide it. Later, at school, Genya avoids eye contact with Sanemi, sitting with his friends and whispering. Sanemi can hear them snickering, knowing they're gossiping about him getting dicked down. He slams his chalk down in class.
"Quiet! Or you're all getting detention!"
He glares at Genya specifically, who is with Tanjiro and Inosuke. Tanjiro looks sympathetic but can't help giggling.
"Tanjiro, front row. Now."
Sanemi wants to make an example of him. Tanjiro moves reluctantly, the other students snickering more. Giyuu walks past the hallway outside, oblivious to the chaos he caused. During lunch, Sanemi corners Genya in the cafeteria.
"Did you tell anyone else?"
He grips his brother's shoulder tightly.
"N-No, but I might slip up if you keep being scary."
He looks like he wants to cry, intimidated by his older brother's wrath.
"I swear if I hear a rumor..."
He lets go and stomps off, seeing Giyuu enter with his bento box. He has the urge to drag him into the supply closet. Giyuu notices Sanemi's hostile expression and casually waves at him, eating his ohagi. Sanemi clenches his fists, wanting to choke him with it. The wave triggers a memory of Giyuu feeding him last night.
"Stop waving like that!"
He mutters under his breath, getting more flustered. Students see this interaction and start whispering again, connecting the dots. Sanemi's ears turn red.
"Want some?"
He offers him a piece. Sanemi glares at the students and then at Giyuu.
"No. I'm going to Iguro's office."
He needs to rant to someone who hates Giyuu too. Iguro is organizing his desk when Sanemi bursts in.
"What's with the racket, Shinazugawa?"
He notices Sanemi's disheveled appearance and raises an eyebrow.
"He topped me last night."
Iguro nearly drops his snake keychain.
"You let Tomioka top? He doesn't even speak enough!"
He's equally shocked and disgusted.
"It just happened! I hate that he's so good at it."
He paces back and forth, unable to admit how much he liked it.
"You should have dominated him instead. That's how he should act."
Iguro crosses his arms, thinking.
"He's probably smug about it. He should be ashamed."
Sanemi slams his hand on the desk.
"He's so fucking expressionless that I can't tell!"
"I'll make sure to avoid him more. Can't stand that poker face."
He looks out the window, seeing Giyuu talking to a student.
"Watch him, he's plotting something."
The student runs off and Giyuu glances up at the window, seeing Sanemi. He gives a tiny smile.
"See? Plotting!"
Iguro hisses. Sanemi feels his heart skip, then scowls at Iguro.
"Damn it, he's doing that on purpose."
He can't tell if it's mocking or genuine. Class resumes. Sanemi avoids looking at Giyuu, but he can't shake the image of last night. He starts writing math equations angrily on the board.
