The heavy iron door slams shut, sealing the inmates in their communal cell. The air is thick with testosterone and anticipation. One by one, the convicts strip, their muscles glistening under the harsh fluorescent lights. With no lube or mercy, they take turns pounding into each other, their bare cocks sliding in and out of tight, hairy asses. Grunts and groans echo off the cold concrete walls as they rut like animals, driven by primal instincts and pent-up desires.
