Jacob, a twink with a penchant for straight boys, can't help but notice the bulge in his shorts, his cock throbbing with anticipation. He decides to indulge, pulling out his thick, uncut dick and starting a slow, sensual jerk session. His hand glides along the smooth, veiny shaft, his grip tightening as he increases his pace. His hips buck, and his breaths grow heavier, the familiar surge building in his loins. With a final, swift stroke, he lets out a guttural moan, his body convulsing as he gushes hot, white cum all over his stomach and hand, a satisfied grin spreading across his face.
