The gym's echoing silence is shattered by the lewd sounds of Oliver and Argos' taboo encounter. Argos, the dominant brother, has seduced Oliver into a world of homoerotic pleasure. Oliver, once hesitant, now moans loudly as Argos' bare cock pounds his ass in the doggy position. The weight bench creaks under their intense fucking, Oliver's pussy-like asshole stretched wide around Argos' thick cock. Argos' cockhead rubs against Oliver's prostrate, sending waves of pleasure through him. Oliver's own cock, untouched, leaks pre-cum onto the gym floor. Argos, nearing his peak, grips Oliver's hips tightly, his cock swelling inside Oliver's ass before he erupts, filling his brother with hot, sticky cum. Oliver, spent and satisfied, collapses onto the bench, his own cock still hard and aching.
