Dieter Muller, alone in his dimly lit room, begins a private dance, his hands roaming over his muscular body. He teases himself, pushing the fabric of his underwear against his growing bulge. Slipping a hand inside, he grips his hardness, stroking it slowly, a bead of sweat forming on his brow. His breath hitches as he picks up the pace, his other hand playing with his heavy balls. Dieter's body tenses, his abs clenching as he nears the edge, his grip tightening. With a low groan, he comes undone, hot cum spilling over his fist.
