Mathias, a strapping, hairy, tattooed man, finds solace in the confines of his private space. He strips, revealing his average-sized, yet enticing cock, already throbbing with anticipation. The room fills with the sound of his heavy breathing as he begins to stroke, his eyes closed, lost in his own world of desire. His hand grips his shaft firmly, moving up and down with increasing urgency. Pre-cum glistens at the tip, a testament to his growing excitement. He leans back, his body tensing as he nears climax, before finally letting out a guttural moan, his hot seed spilling out onto his hand.
