[Manaita Koujou (Miginer)] Imouto-chan wa Arawaretai!! 4

Mitsu wants nothing more than her brother's undivided attention, and bath time gives her the perfect opening to scrub him down with eager little hands — until he decides she's earned a reward of her own. He takes his time spreading her smooth pussy open for a close, embarrassing inspection before burying his face between her thighs, leaving the blushing girl squirming and gasping under his tongue. The fourth entry in this sibling series winds down with the two curled up under a blanket, fast asleep and more attached than ever.
