ZUKO-087: Mischievous Baby-making with My Four Little Sisters - Usami Mai

About this work

Big brother (you) must dedicate everything to the little sisters. To make sure their bodies develop healthily, you knead around their chests in the bath, sleep with them and stimulate the groin area, and in some cases inject semen into all of them to adjust their hormone balance. But why do the sisters hardly appreciate these efforts and sometimes find them disgusting? …That's because you walk into the room with your pervert face on and a fully erect cock, like some lecherous count.
