Summary
After somehow ending up dating his best friend, Tsukasa is struggling to keep up with Rui’s constant sexual advances. While he is enjoying the things they do together, he has absolutely no intention of giving in to Rui’s main wish. He’s sure that nothing can make him change his mind in that regard, but after one of their encounters reminds Rui of an old fantasy, Tsukasa is met with a tempting offer that might just make his resolve shake: if he promises to grant him his wish, Rui will let him do the same to him...?!

Summary
In their first year of living together, Tsukasa is looking forward to spending his whole birthday with his boyfriend. It doesn’t go exactly as expected when most of the day goes by with Rui acting strangely distant, too busy with something else to celebrate with him. Tsukasa tries to convince himself that he must be preparing an extra special surprise for him, and that’s why he’s taking so long to even wish him a happy birthday, but… the more the time passes, the harder it becomes to find ways to justify Rui’s behavior.
There’s no way he actually forgot his birthday, right…?

Summary
“T-Tsukasa-kun, I’m not sure if I’m ready for this after all…”
“You’ll be fine,” Tsukasa calmly assures as he finishes preparing himself, taking his fingers out to bring his ass closer to Rui’s dick. “And you owe me this much for always testing things on me, right? It’s only fair that I ask for a small favor from time to time!”
“A small favor…” Rui repeats as he looks down at himself. The small vibrators on his nipples; the one in his ass that he can’t really see but can surely feel; Tsukasa above him, about to sit on his dick. “...I think it might kill me.”

Summary
The air around him feels heavy. The colors of their room look dim. His chest that should be filled with warmth feels tight. Not a single thing about this feels right.
But stopping feels even more wrong. Even if everything feels cold, mechanical, like an act done out of obligation instead of love, he can’t stop. He can’t stop. He can’t let Rui realize what’s going on. Because if he does, he’ll lose him. He’ll lose the most important thing in his life.
And if he loses him, what will he have left?

Summary
Rui was a happy bee. He had the best boyfriend in the world, the prettiest, the most caring, everything he could ever want. Life was perfect. He couldn’t ask for more.
…is what he’d like to say, but something was actually bothering him more and more as time went on. Sure, their relationship was great. He loved Tsukasa, Tsukasa loved him, they were always there for each other, they even went on dates often. But Tsukasa was human, absurdly bigger than him. Which meant, Rui would never get to fuck him. All he could do was... take advantage of his small size to spy on Tsukasa.

Summary
As they walked home from school, Tsukasa and Rui continued their usual chat, talking about their day, about new ideas for their shows, and about their goals.
The more Rui listened to Tsukasa, the more a familiar need sparked within him. He had managed to keep this urge under control, especially because of how busy they had been recently, but now that things were calming down, it was resurfacing stronger than ever. That's why he decided to invite Tsukasa home.
A slice of life story set in a Dom/Sub verse AU.

Summary
“Well, I can tell you all the science and theory you want, but I firmly believe that a proper hands-on experience will teach you more than any article or biology book will. I can help you with that… if you want," the last part comes out hushed. His previous certain smile wavers along with his voice, realizing the way he was presenting himself, the implications of his own words.
☆
What are you supposed to do when the person you’ve been longing for seasons on end asks you a sensitive question? For Rui, that answer is obvious: you simply lay-off the rational parts of your brain, let all your brain cells die and offer yourself to help.
