Gym floor in white leggings, GrowingMuscleBro grips his stiff cock and grinds it hard through the stretch, fully committed

In the gym, GrowingMuscleBro sits with his legs spread in tight white leggings with a grey stripe down the side. One hand cups the outline of his cock through the fabric, the thick shaft pressing hard against the stretchy material. He squeezes and strokes along the bulge, tracing it as it strains against the seam. He tilts his hips up, the shape of his dick pushing sharply into the white cloth.
