In the dimly lit, cramped public toilet, Riku and Kei's heavy breaths echo, mingling with the distant hum of the city outside. Riku's hands, rough with callouses from years of manual labor, grip Kei's hips, pulling him back onto his thick, uncut cock. Kei's body stretches to accommodate Riku's size, their groans of pleasure and pain intermingling. The scent of sex and sweat fills the air, drowning out the harsh chemicals of the public restroom. Riku's pace quickens, his fingers digging into Kei's flesh, their bodies slapping together in a rhythm that echoes through the tiny space. Kei's cock, hard and untouched, swings freely, leaking pre-cum onto the filthy floor as Riku fucks him hard, chasing their shared release in the forbidden, exhilarating dance of public bareback sex.
