In the warm embrace of his jacket, Shankuji finds solace and arousal. His hand wanders, tracing the curves of his body, landing on the stiffening bulge in his pants. He unzips, allowing his thick, veiny cock to spring free. With a sigh, he begins to stroke, the friction and the warmth of his jacket intensifying the sensation. His other hand cups his balls, gently rolling them, as he picks up the pace. Pre-cum leaks from his slit, and he uses it to lube his shaft, the slickness allowing him to pump faster. His breath hitches as he feels the familiar building of pressure. With a final, hard stroke, he comes, his cock pulsing as ropes of cum shoot out, coating his abs and the inside of his jacket.
