[T.4.P (Nekogen)] Ichinen-buri ni Atta Imouto ga Nanka Sugokatta Ken. [FC]

After a year apart, Minami the tomboy pixie-cut little sister has returned unrecognizable to her older brother, now a soft, busty oppai loli whose sleeping body and heavy, bouncing oppai prove impossible to ignore. Sharing a bed turns innocent dozing with closed eyes into agonizing temptation as her teasing nearness wears down his restraint. What begins as a guilty glance spirals into a sweaty, tender defloration where the once-boyish sister begs for her brother's creampie and neither can get enough.
