Summary
“I hate it. I hate it so much,” Akito’s lip wobbled, pausing for a moment, “Because I–... I’m so… so jealous of him.”
There were no fireworks. The ground didn’t open up beneath them, swallowing the two of them whole. There wasn’t an audience to let out a gasp of surprise; all there was, was silence.
And the slow drag of Tsukasa’s hand across the soft spot between his shoulder blades.
OR
Akito is starting to hate Toya. Ridden with jealousy and resentment for his boyfriend, Akito finds comfort in the one place he shouldn't be finding comfort—his boyfriend's brother, Tsukasa. (in other words, akito cheats with tsukasa: the fic!)

Summary
“You’re…”
Akito gulped weakly again, and he trailed his hand down from Tsukasa’s forehead to his cheek, cupping it gently.
“You’re an Omega… You’re going through your first heat.”
---
Tsukasa and Akito meet to study for a test in the library, and Tsukasa unexpectedly presents as an Omega in front of Akito, who happens to be an Alpha. Akito couldn't just leave him sitting in the library, vulnerable to other Alpha's; he had to help his poor, incredibly attractive senior.

Summary
“Tsukasa, please tell me if I’m reading this right.”
Tsukasa couldn’t resist the urge to reach out and grab Akito’s hips, fingers digging into the fabric of his pants as if he pressed hard enough he would be able to feel the skin underneath. Tsukasa’s eyes were blown wide, swimming with pleasure and desire.
“Of course you are, Akito.”
---
Where Tsukasa gets a chance with Akito, and promptly becomes addicted. His feelings are reciprocated in a sense, though Tsukasa's desire only seems to grow and grow until it develops into obsession. He can't seem to get the taste of Akito out of his mouth, nor the image of him out of his head.
a fic based off the song affection addiction by vocalokat! if u know the song you'll be able to catch some lyrics sprinkled throughout, but they're not obvious

Summary
part two of my other work "tiring road trip"! you should read it before this one so you're not confused!
---
He brings the clump of clothes to his chest, covering himself and sagging his shoulders. He really should be getting back to the group, it was probably weird how long he was spending in the bathroom when he’s only supposed to be changing his clothes, but he couldn’t drag his eyes away from the mirror.
As much as he hated everything he saw, how much he dreaded other people seeing himself like this, he couldn’t look away. It was like he was stuck in hypnosis, except it drags him further into a hole of self-pity and disgust, rather than a funny dreamland.
OR
day two of WXS and VBS + Mizuki vacation! they have fun at the beach together, but akito struggles with his self-esteem and body image, and tsukasa makes sure he ends the day feeling more confident in himself. (basically tsukasa compliments and praises akito while he fucks him!)

Summary
Tsukasa scotted back, his back pressed against Akito’s chest as far as he could in order to make the seat belt fit. Akito gave a choking noise, his cheeks going slightly red.
“Restrict my breathing more, would ya?” Akito scowled at him, trying to move so he could breathe better, when a sudden realization dawned on him. His face went even more red as he felt Tsukasa move on top of him, his ass pressing against Akito’s crotch as he moved over to click the seat belt in.
When it finally clicked, Tsukasa sighed with relief, “Sorry, Akito-kun! I’ll move now…” He shimmied his hips forward, ignoring the tightness of the seatbelt in favor of making Akito more comfortable. Akito’s face went beet red and he grit his teeth together as he felt Tsukasa move in his lap, refusing to look down until he felt the pressure mostly off of his dick.
OR
WXS and VBS + Mizuki go on a vacation to Emu's beach house. There's not enough seats in the car, and Tsukasa ends up sitting on Akito's lap in order to make them all fit. horny teen shit ensues

Summary
It was an odd feeling having someone’s head in his lap, as he never really let anybody sleep there before, but he brushed it off as he opened his luncheon quietly. He ate in silence and made sure to eat carefully, as didn’t want to wake Akito. Tsukasa was enjoying the peaceful silence with his, admittedly, very adorable junior, who only looked even cuter like this!
Finishing his luncheon, he pulled out the latest script for his play, wanting to spend the time doing annotations. He looked over the script intensely, but his thoughts were cut short as he felt Akito adjusting below him.
Oh…

Summary
Akito and Tsukasa frequently sneak off to the abandoned classroom on the third floor during lunch to fuck when they can. For months it was just the two of them, but one accidental phone call leads to something else, and soon Rui is joining them. The more the merrier, after all.
- - -
Akito and Tsukasa fuck and then drag Rui into it on accident. (they secretly have romantic feelings but they're horny teens so they only focus on their sexual feelings)
