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
