Under the harsh fluorescent lights, Brazilian gym rats exchange hungry glances. One, a toned twink, grunts as he pumps iron, his gaze flicking to the other's tight ass.

The air grows thick with tension, their imaginations running wild with thoughts of illicit encounters, as they struggle to maintain focus on their workouts and not each other's tantalizing bodies.
