In a dimly lit room, three straight mates, adorned with tattoos and natural hair, explore the boundaries of their friendship. They start with innocent masturbation, their trimmed cocks standing at attention. One, with a mischievous grin, proposes a 'piss-off.' They laugh, but the idea sticks. They stroke, their balls heavy with anticipation. The first stream arcs, splashing onto the floor. The room fills with the sound of urine hitting surfaces, the scent of sweat and piss. They slip and slide in the mess, their cocks glistening, their laughter echoing as they push each other's limits.
