The weight of the jacket on his shoulders, the rustle of fabric as he moves, the chill of the room against his exposed flesh - every sensation amplified by his solitude. His hand wraps around his throbbing cock, the friction sending jolts of pleasure through him. He imagines a stranger's hands, a stranger's mouth, a stranger's body pressed against his. His strokes quicken, his grip tightens, until he's gasping, his cock pulsing, spilling his load into the silence, the jacket his only witness.
