With a neighbor's screams of pleasure providing the soundtrack, a lonely man turns to his trusty shampoo bottle for solace. He works it into a lather, the slippery liquid coating his eager hand as he strokes himself with increasing fervor. The moans next door grow louder, more insistent, pushing him to the brink. His breath hitches, his grip tightens, and with a final, guttural groan, he finds his release, his own cries joining the chorus of carnal delight echoing through the thin walls.
