[Nishikawa Kou] Ane no Sumika | My Older Sister's Love Nest [MTL]

An eager younger brother knocks on his older sister's door, shouting "Big sis, I'm here!" and is met by her shocked, panting face as she asks what kept him away. She pulls off her glasses, exposing her large, hairy breasts and wet, hairy pussy, and they dive into a heated, incestuous encounter filled with kisses, moans, and playful teasing of her nipples. Afterwards they cuddle in a bathtub, where she declares that their future hinges on where his big sister lives, sealing their bond.
