In the dimly lit dungeon, a muscular black man lies back, legs spread, as his partner teases his eager urethra with a glistening metal probe. The sounder's gloved hands slowly insert the cold, smooth metal into the sensitive opening, watching as the thick cock twitches and hardens. The man on the table groans, his body tensing as the probe reaches deeper, stimulating his prostate with expert precision. The sounder twists and turns the metal rod, drawing out moans and gasps, before slowly sliding it out, leaving the man craving more.
