About
Hayato and Jyutaro are college students. Alarmed by their daily, relentless sexual activity, Jyutaro challenges Hayato to a bet: one month of abstinence—no sex, no masturbation, and only one kiss per day. The loser has to do whatever the winner says. However, less than two weeks in, Jyutaro backfires on his own one-kiss-a-day rule. He's the one who suggested it, yet he's the one reaching his limit from the thirst of not being touched. Hayato, not missing a beat, starts teasing him mercilessly...

Intro
...Haa, ...ngh, ...nnh, Sinking into the sheets, Jyutaro stared blankly at the ceiling through the gaps in his messy bangs. A violent pulse throbbed in his ears. Hayato's body heat and scent clung to his entire skin.
Suddenly, his eyes fell on his smartphone as a notification chimed by the pillow. Seeing the time on the screen, Jyutaro snapped back to reality. He had a first-period class tomorrow.
The clock had long since passed 1:00 AM. To make matters worse, on the chest of Hayato—who was lying next to him looking satisfied and saying "Ah, that was the best"—were the vivid red marks Jyutaro had just desperately left there.
