Based off another Mairi story I've seen.
I'm not tagging the author cuz frankly, I don't care enough anymore.
---------------------
Kairi had been teasing Mattia all day. Small actions, like placing his small hand on Mattia's thigh while they ate, or giving his waterbottle a very discreet handjob.
Mattia wanted to slam the boy onto the table and fuck him until he cried but he couldn't because they were at Alejandro's house.
Mattia was watching Kairi intently as the boy was eating a popsicle. Kairi noticed Mattia's eyes on him and decided to tease him further. He pushed the popsicle as far down his throat as possible without gagging. He held it there for a few seconds before taking it out of his mouth and licking along the sides. Mattia shuddered, willing himself not to get hard as he imagined Kairi's mouth doing those things to him. He was snapped out of his thoughts at Alejandro's voice.
Ale: so do you guys wanna sleep over? Or-
M: sorry Ale, we've got a date tonight.
Kairi looked mildly confused but he nodded slightly.
M: I promised Kairi I'd take him out tonight.
Ale: oh yeah no problem.
M: we've actually gotta leave right now.
Alejandro and Kairi both looked rather confused but Mattia quickly stood up grabbing Kairi's wrist and pulling him through Alejandro's backyard and out to Mattia's car.
M: bye Ale. See you tomorrow.
Mattia didn't wait for a response as he pushed Kairi into the car and got in the drivers seat. They started driving to Mattia's house in silence.
K: what the hell was that?
Mattia ignored him.
K: you probably offended Alejandro. Leaving like that.
Mattia didn't say anything but he reached one hand over and placed it high up on Kairi's inner thigh. He squeezed tightly, enjoying the way that Kairi's breath hitched.
The rest of the car ride was silent and when Mattia finally parked in the drive way and took his hand off of Kairi's thigh, the other boy stared straight ahead.
M: upstairs. Now.
Kairi didn't respond as he opened the car door and ran into the house, Mattia following behind him. By the time Mattia stood in the bedroom door way, Kairi was sitting delicately on the edge of the bed. He had taken his shirt off but had not gone any further.
Mattia was wordless as he took his belt off, walking slowly towards the bed.
M: I bet you thought it was pretty funny hm? Teasing me like that? All fucking day.
Kairi shook his head rapidly, suddenly fearful of what Mattia was going to do.
Mattia pushed him backwards into the bed, bringing his hands above his head and securing them to the bedpost with his belt.
K: wait Mattia. I-
M: do I need to gag you too?
Kairi went silent. His cheeks heating up. Mattia proceeded to take Kairi's pants off, leaving him exposed and vulnerable.
M: much better.
Kairi blushed under Mattia's intense gaze, closing his legs. Mattia frowned and pushed his legs open again.
