"Are you really that curious about my slit?" When his bratty niece Akari finds out he's been sneaking a peek, her weak-willed uncle is defeated by her temptation to show off his immature pussy. Since then, he's captivated by her sweet-smelling slit, licking her crotch in the morning and even licking her after she urinates. Kicked out of the house and with nowhere to go, Akari calls him "strong uncle," but she also comes to depend on him and desire him. The two spend their dull days filling each other's void with a sweet and sadistic life.
