"But we really should go now. Clean the car and I tidy myself up."
Sanemi reluctantly pulls out, watching his cum leak out of Giyuu's hole.
"Fine. But this isn't over. I'll make you pay for being such a good teacher later."
He starts fixing his clothes, smirking at the mess they've made.
The evening they spent not together. Because Genya is piss, because Inosuke and Giyuu's adopted kids Muichiro and Nezuko are tired. So they drive separate ways. Sanemi arrives home with Genya, he have an annoyed expression on his face.
"What's with that face, brat?"
Genya crosses his arms.
"Where were you all this time? You disappeared during the firework show."
He narrows his eyes suspiciously at his brother.
"I had some... personal matters to attend to. None of your business."
He tries to walk past Genya but is stopped by his brother's hand on his shoulder.
"Personal matters? Bullshit. You were with Tomioka, weren't you?"
His grip tightens as he confronts Sanemi directly.
"You know he is my boyfriend."
"Yeah, and I also know you two were probably doing something inappropriate. I saw the way you looked at him during the festival."
He lets go of Sanemi and sighs in frustration. Sanemi growls defensively.
"So what if I was? We're adults. We can do whatever we want."
He clenches his fists, feeling protective of his relationship with Giyuu.
"Just... be careful, alright? I don't want you getting into trouble at school because of him."
There's genuine concern in his voice despite his annoyance.
Sanemi softens slightly at Genya's concern, but maintains his tough demeanor.
"I can handle myself. And Giyuu isn't a bad influence. He's... different with me."
Meanwhile at Giyuu's home and is sitting in his living room, trying to focus on grading papers but keeps thinking about Sanemi. He absentmindedly touches the fresh hickeys on his neck, a small smile forming on his usually stoic face. His phone buzzes with a text from Sanemi.
Sanemi:
Missing me already, Giyuu?
The message is accompanied by a picture of Sanemi smirking in his car. Giyuu blushes and quickly types back.
Giyuu:
Shut up. I'm trying to work.
He bites his lip, remembering how
Sanemi called him a good teacher earlier.
Sanemi:
Work can wait. I want to see you tomorrow morning.
He sends another message with a suggestive emoji. Meanwhile, Sanemi is lying in bed, already planning their next encounter.
Giyuu:
Tomorrow I can't, because Sunday is family day.
Sanemi:
Family day? Tch, I'm family now too.
Giyuu:
You know what I mean. My students' parents are coming to the school for an open house.
He feels guilty for having to decline Sanemi's invitation, but knows it's important for the students.
Giyuu:
And Monday we teaching the afternoon club about sports and mathematics. So no need to worry not to see me.
Sanemi:
Fine, whatever. Just don't let those kids keep you too busy. I'll be watching you.
Giyuu:
You're always watching me, Sanemi. Even when you're not there.
Sanemi:
Damn right I am. Those kids better not get any ideas about you.
Giyuu:
I'm not interested in anyone but you, you possessive bastard.
Sanemi:
Good. Now go to sleep before I come over there and show you who you belong to.
His protective instincts are kicking in, and he's struggling to resist the urge to drive back to Giyuu's place.
Giyuu:
Don't tempt me, Sanemi. I have papers to finish.
He's secretly tempted to let Sanemi come, but he knows he needs to stay responsible.
Sanemi:
You're such a tease,Giyuu. I'll see you at school then.
He reluctantly accepts defeat, but plans to make Giyuu pay for it later. Monday morning, Giyuu arrives at school early, as usual. He spots Sanemi talking to Obanai in the teacher's lounge. Sanemi glances at Giyuu and smirks. Obanai notices the marks on Giyuu's neck.
"Oh, looks like someone had a fun weekend."
He points at Giyuu with a knowing look. "Shut it, Iguro."
He tries to act nonchalant, but his eyes are locked on Giyuu's neck with pride.
"No wonder you're always in such a good mood after seeing him, Shinazugawa."
He laughs and takes a sip of his coffee, enjoying the awkward tension.
Sanemi grits his teeth and moves closer to Giyuu.
"I'm not in a good mood."
He stands protectively beside Giyuu, trying to shield him from Obanai's comments. Giyuu raises an eyebrow at Sanemi's defensive stance.
"Sure, sure. Keep telling yourself that."
He grins wider, clearly enjoying Sanemi's reaction. Shinobu walk to Giyuu and starting teasing him. Sometimes she pokes his cheek or something. This is making Sanemi jealous, really jealous. Sanemi growls under his breath as he watches Shinobu interact with Giyuu, his fists clenching.
"Good morning, Giyuu-san! You seem different today."
She notices the hickeys too and gives Sanemi a mischievous glance.
"Morning, Shinobu. What do you mean different?"
He tries to remain calm, but he can feel Sanemi's jealousy radiating off him.
Sanemi steps forward, grabbing Giyuu's wrist possessively.
"He's just tired. Leave him alone."
"Oh, is that so?"
She smirks at Sanemi's grip on Giyuu's wrist and Obanai chuckles again.
"You're too obvious, Shinazugawa."
"I said back off."
His voice is low and threatening, his eyes darkening with anger. He pulls Giyuu closer to him, marking his territory.
"Sanemi you are to protective."
"And you're too friendly with everyone. Especially her."
He shoots a glare at Shinobu, his possessiveness getting the better of him. Shinobu giggles.
"Jealous much?"
She playfully sticks her tongue out at Sanemi, knowing exactly how to provoke him. Sanemi snaps.
"I'm not jealous! I just don't want you touching him."
He wraps his arm around Giyuu's waist, claiming him in front of everyone. "Sanemi, calm down. You're causing a scene."
He places a hand on Sanemi's chest, trying to soothe him but secretly enjoying the attention.
Sanemi softens slightly at Giyuu's touch but still glares at Shinobu.
"Aww, how cute. The big bad math teacher is being all protective."
She winks at Giyuu before walking away, satisfied with the chaos she's caused. Giyuu sighs and turns to Sanemi.
"You really need to control your temper."
He leans against Sanemi, whispering* But I like it when you're possessive.
Sanemi smirks, his mood instantly improving.
"Shut up and let's go to class."
The bell rings, signaling the start of the school day. Students begin filling the hallways.
"Sanemi grabs Giyuu's hand I'm walking you to the gym."
