[Juicebox Koujou (Juna Juna Juice)] Annoying (Step) Sister Needs to be Scolded!! Two~ [Full Color]

Onii-chan tries to keep his little stepsister in line with a firm hand and some strict "lessons," but the bratty, pigtailed girl with the big glasses and wide hips clearly has other plans in mind. She coaxes, teases, and promises to be his sweet "coting" student in exchange for a good scolding, melting his resistance until the two are tangled together in a sweaty, full-color tumble of domination and surrender. What starts as sibling discipline spirals into an intense, taboo romp that leaves them both breathless, blushing, and craving another round.
