Brunette girl gets touched by guy in living room

The brunette girl, likely in her 20s, sits on a chair in a living room, bending forward with her head down. A guy, also in his 20s, stands behind her, placing his hand on her stomach and later on her buttock. The room is lit by natural light from a window, and there’s a mirror on the side, reflecting their actions. The girl has long brown hair and appears slender, while the guy seems muscular and wears a watch on his wrist. At one point, she takes a selfie of her buttock, showing a red mark.
