With a provocative glint in her eye, Karin's slender form teases Kensuke, her small tits bouncing enticingly as she moves. He can't resist, pinning her down and pushing her uniform skirt up to reveal her tiny panties. She squirms, trying to escape his grip, but his hard cock presses against her, seeking entrance to her tight, wet pussy. Despite her initial resistance, her body betrays her, responding to his touch with eager lubrication.
