As the sissy's eyes gleam with lust, they position themselves on all fours, ass high in the air, ready for the fuck machine's unyielding onslaught. The machine whirs to life, the dildo slamming into the sissy's willing hole with brutal force. The sissy cries out, their fingers digging into the floor as they struggle to maintain their position. The machine's speed increases, the dildo pistoning in and out, filling the sissy completely. They cum repeatedly, their body wracked with shudders, their cries echoing through the room as the machine continues its relentless pace, driving the sissy into a state of cum-drunk oblivion.
