[Flicker10 (Kuronyan)] Natsu No Owari

A heavily pregnant married woman returns to her rural hometown to give birth, only to find her younger cousin waiting at the same river where he once begged to share her bath. Nostalgia curdles into desire as he worships her enormous breasts and taut swollen belly, and though she teases him for being a pervert who can't look away, she spreads her legs and invites him in anyway. With her husband far away and the last days of summer slipping by, Yuki cheats on her marriage with the one boy she should never touch, surrendering to a forbidden heat that ends only with birth itself.
