YST-354 — Minato Haru silently devoured his younger sister who had just started cosplaying.

Haru, the younger sister, is cleverly manipulated by her older brother, a pervert who loves fetish play. Under the guise of a cosplay photoshoot, he takes erotic photos of her, then half-forcibly shoves his foul-smelling cock into her mouth, forcing her to perform fellatio and anal sex, making her swallow his semen. Her small breasts are roughly kneaded, and her pubic-hair-covered pussy and anus are licked, causing her to moan with pleasure. Her eyes change color, and she herself craves her brother's fierce cock, devouring it with her lewd pussy, and begging him to cum inside her as he thrusts violently, making an ecstatic face.
