[Sakaetenai desu. (Sakae)] Succulent Sweet Sex with an Impertinent Little Sister that Loves Her Oniichan [Aruha]

A bratty little sister's bravado crumbles the instant her onii-chan's cock springs free, her awed "wow..." dissolving into a flustered "you're going to thrust this thing into me?" as she squirms on the hotel bed. Between his teasing promise that he could do "a lot of things to Hina-chan every day" and steamy bathtub kisses where she breathlessly whispers "onii...", the siblings' secret rendezvous turns achingly tender. What follows is sweat-slicked sex with her small breasts heaving and legs spread wide, her cries of "it feels so good there" proving this impertinent imouto is utterly hooked on her brother.
