In the intimate confines of his private space, a man in a form-fitting, skintight zentai suit indulges in his solitary pleasure. The suit, a second skin, leaves little to the imagination, accentuating every curve and contour of his body. He strokes himself tentatively at first, the suit's material providing a unique texture and sensation. His movements become more assertive as he loses himself in the moment, the suit's built-in penis guard a constant reminder of his submission and restraint.
