ZUKO-087: Mischievous Baby-Making with My Four Little Sisters - 宇佐美まい

About this work

Big brother (you) must devote everything to his little sisters. To ensure their bodies develop healthily, you knead around their chests in the bath, sleep together and stimulate the groin area, and in some cases even inject semen into all of them to help regulate their hormone balance. But why do your efforts fail to reach the sisters and sometimes make them feel disgusted? …That's because you walk into the room looking like a pervert, fully erect like a lecherous count.
