Under the cloak of night, an unseen performer retreats to their private space, the dim glow of their device casting a sinister silhouette. Their hand, slick with anticipation, strokes their throbbing member, the sound of wet flesh on flesh echoing in the silent room. The tempo increases, breath hitches, and with a guttural moan, they erupt, their load painting the walls, the floor, a testament to their solo indulgence.
