Ass grind on bathroom rug close-up

A person kneels on a textured bathroom rug, wearing a short-sleeved top and thong underwear, grinding their hips back toward the camera. The shot is low-angle and tight on the rear, capturing hand movements on the hips and thighs. Background shows a shower curtain, wall-mounted storage, and framed art, all in black and white. The mood is intimate and focused on body movement.
