A man, alone with his thoughts and desires, indulges in the primal act of self-love. His hand, slick with pre-cum, glides effortlessly along his engorged shaft, the friction sending electric jolts through his body. He imagines a lover's touch, his mind painting vivid images that fuel his arousal. His balls tighten, his abdominals flex, and with a low groan, he finds his release, his cock pulsing as he coats his hand and abdomen with his essence.
