Giyuu look at his phone and got ten missed calls from Tanjiro. Sanemi notices Giyuu's phone.
"Who the hell is calling you so many times?"
"Oh shit the kids! They are alone at home."
Sanemirolls his eyes and pulls out slowly.
"Of course they are. You forgot about them again, didn't you?"
He starts fixing his clothes while Giyuu panics about the kids. Sanemi smirks at Giyuu's defensive response.
"No!"
"Then why didn't you answer them? You were too busy getting fucked."
Giyuu blushes deeply, realizing Sanemi is right.
"Shut up... I need to call them back."
He tries to sit up, wincing from the pain in his lower body. Sanemi grabs Giyuu's wrist before he can reach for his phone.
"Let me drive you home first. You can barely move."
Giyuu gives in reluctantly.
"Fine... but they're going to be worried sick."
He slumps back in the seat, still feeling Sanemi's cum dripping out of him. Sanemi starts the car and drives off.
"Don't worry, I'll get you there fast. Just don't pass out on me."
The drive is silent except for Giyuu's occasional winces of discomfort. Sanemi occasionally glances at him with a satisfied smirk.
Sanemi pulls up to Giyuu's house.
"You better clean yourself up before you face those kids. You look thoroughly fucked."
Giyuu checks himself in the mirror and sees the multiple hickeys and bite marks.
"Damn it, Sanemi..."
Sanemi chuckles darkly.
"What? You're the one who begged for it. Now deal with the consequences."
Giyuu glares at him but knows he can't argue again.
"Just... stay here while I go in."
Sanemi smirks wider.
"No way. I'm coming in with you. I want to see their faces when they see their dad like this."
Giyuu panics again.
"No, you can't! They'll know something happened!"
"But I want to see their reactions."
He frantically tries to cover the marks with his shirt collar.
"Than be my boyfriend.
Sanemi freezes for a moment, caught off guard by Giyuu's sudden boldness.
His eyes widen slightly before narrowing again, a mix of surprise and possessiveness in his gaze.
Sanemi leans in close, his voice low and intense.
"You're serious? After all this time, you're finally asking me?"
Giyuu nods, his heart racing as he waits for Sanemi's response.
Sanemi smirks and kisses him roughly. "Then I'll be your boyfriend, Giyuu. But don't think I'll go easy on you now."
Giyuu melts into the kiss, relief washing over him. Sanemi pulls away and grabs his hand.
"Now let's go face those kids. And remember, you're mine."
They get out of the car and walk to the door. Sanemi keeps a possessive grip on Giyuu's hand, not letting go even as they enter.
Tanjiro's eyes widen in shock seeing Sanemi and Giyuu together.
"Giyuu-san? Why is Mr. Shinazugawa with you? And why are you..."
He notices the hickeys and bites, his concern turning to confusion and suspicion. Sanemi smirks at Tanjiro's reaction, enjoying the tension.
Tanjiro steps forward protectively.
"Giyuu-san, did he hurt you? You look... different."
Giyuu tries to speak but Sanemi cuts him off.
"I didn't hurt him. In fact, he enjoyed every second of it. Right, Giyuu?"
He squeezes Giyuu's hand tighter, challenging Tanjiro with his gaze. Tanjiro blushes furiously and looks between them, realization dawning.
"Wait... you two are...?"
He seems torn between wanting to protect his stepdad and being happy for him.
Sanemi wraps an arm around Giyuu's waist, pulling him closer:
"Yes, we are. Got a problem with that, kid?"
Giyuu smack Sanemi's head. Sanemi rubs his head and growls at Giyuu.
"Ow! What was that for?"
Tanjiro giggles slightly, finding the interaction amusing despite his initial shock.
Stop being rude to him.
Sanemi pouts childishly:
"I wasn't being rude. I was just stating the obvious."
Tanjiro laughs more, relaxing a bit.
"It's okay, Giyuu-san. I think I can handle it."
"You little..."
Sanemi starts to say something but stops himself, knowing he's in front of Tanjiro. "Are Nezuko and Muichiro already in bed?"
"Yeah, they went to bed early. Nezuko was tired from the mixer and Muichiro just... well, he's Muichiro."
Tanjiro glances at Sanemi curiously, still processing everything. Giyuu sighs in relief.
"Good. I need to talk to you privately, Tanjiro."
"Okay, Giyuu-san."
Tanjiro turns to Sanemi while Giyuu look at Sanemi.
"You can wait here."
Sanemi scowls but nods reluctantly.
"Fine. Don't take too long."
He lets go of Giyuu and crosses his arms, leaning against the wall with an impatient expression. Giyuu leads Tanjiro to the kitchen while Sanemi listens in, pretending not to be interested. Tanjiro sits down and looks at Giyuu expectantly.
"So... when did this start?"
Giyuu blushes slightly and scratches his neck.
"Um... today. It's complicated."
"Today? That's... pretty fast. I thought you hated each other."
"I never hated him. I just... didn't know how to express my feelings."
He looks down at the floor, feeling embarrassed. Tanjiro smiles warmly. "Giyuu-san, it's okay. I'm happy for you if you're happy."
He reaches across the table to hold Giyuu's hand.
Giyuu smiles back, touched by his son's acceptance.
"Thank you, Tanjiro. I am happy. Very happy."
"Just promise me you'll be careful. And that he won't hurt you again."
"He won't. I trust him now."
Sanemi, still eavesdropping, feels a pang of guilt and determination to prove himself to both Tanjiro and Giyuu. Tanjiro nods, then whispers something that makes Giyuu blush even more.
"Tanjiro!"
Giyuu's face turns completely red.
"Don't say things like that!" Tanjiro laughs mischievously.
"What? I was just asking if he's a good kisser."
Giyuu covers his face with his hands.
"You're too young to be asking about that!"
Sanemi's ears perk up at the conversation, a smirk forming on his lips.
"I'm not that young! I'm 16! And I've heard things..."
Giyuu groans in embarrassment.
"Please stop talking. This is mortifying."
Sanemi finally can't help himself and calls out from the hallway.
"He's a great kisser, Tanjiro!"
"See? He admits it!
Tanjiro starts to giggle and winks at Giyuu.
Giyuu mumbles under his breath.
"I'm going to kill both of you."
He stands up, face still burning as he heads back to the living room where Sanemi is waiting. Sanemi grins widely as Giyuu approaches, clearly enjoying his embarrassment.
"You're enjoying this too much."
"Of course I am. It's fun teasing you." Sanemi pulls Giyuu onto his lap possessively.
Tanjiro follows, shaking his head with an amused expression.
