The boxer, a strapping young man with a body honed by hours of grueling training, finds himself alone in the gym, his mind wandering to taboo territories. He unzips his shorts, his thick cock springing free, already hard and eager. He works it with his skilled hands, his grip firm and confident, just like when he's landing a perfect jab. He pictures his opponents on their knees, taking his cock deep into their throats, choking on his length. The fantasy fuels his desire, his strokes becoming more aggressive, his grip tighter, until he's groaning and spurting his load onto the canvas, leaving his mark in more ways than one.
