Usotsuki na Tsugai

"I will hold you until my smell permeates you."

Akari, an Omega whose heat period wouldn't come – even after becoming an adult – is despised by his family and called "useless." However, one day, an Alpha appeared who wanted to be paired to someone like him. This man, Shinji, who forced Akari into a heat-like state with medicine, wants to fill up his desires inside many times. "No… something's… coming…!" Akari's body, which should have been immature, is awakened indecently by Shinji.
