In a hidden basement gym, a group of young, smooth-bodied jocks are lured by the promise of a "special" cardio class. Their instructor, a dominant top with a massive cock, leads them through a series of intense, sexual exercises. The boys' bodies glisten with sweat as they're forced to fuck each other raw, their tight holes stretched wide to accommodate the instructor's thick dick. The class ends with a chorus of moans and the sight of cum dripping from well-used asses, a testament to the instructor's relentless, queer desires.
