The room filled with the scent of his musk as I approached, my own cock stirring in my pants. He was a jock, a man's man, but here he was, vulnerable and exposed, his body tensing as he neared orgasm. His strokes became more feverish, his grip tighter. He let out a low groan, his abs clenching as he painted the bathroom wall with his hot, white cum. I couldn't help but watch, entranced by his raw, primal display of masculinity.
