Bound and helpless, the slave's cock twitches in anticipation. Penny and Rita, their eyes glinting with sadistic glee, present the penis pump. The toy's glass bulb shines under the harsh lights, a promise of pleasure and pain. They work together, their hands and mouths in constant motion, the slave's cries echoing through the room. The pump's suction amplifies every sensation, the slave's cock throbbing and pulsing. Rita's asshole swallows the massive, pumped-up dick, her moans joining the symphony of depravity as Penny's tongue laps up the excess, a final, lewd touch to their anal games.
