[Doushoku (Titiduki)] Ottori Onee-chan no Ecchi na Honshou

Satsuki plays the doting older sister to perfection — warm smiles, cozy sweaters, and a figure that barely stays contained — but the moment she pulls her little brother into her room, that gentle mask slips into something far hungrier. Riding him while cooing about making a baby, then dragging him into the family bathroom for a slick, steamy round two that nearly gets caught when someone knocks asking for Minato, she hushes the boy with a wicked grin and keeps going. Whether she's smothering him under her enormous bust or draining him dry with her mouth until he can't hold back, this onee-chan's true nature is a bottomless appetite that turns every sibling moment into a secret neither of them can escape.
