A poor slave wakes up under the legs of his sadistic domina Cleo. He tries to escape, but he can't do anything, because he is still weak. Cleo grabs him from behind, putting an arm around his neck and a hand over his mouth and nose. She uses a very strong grip, so he can't breathe under her hand. Cleo has fun to see her slave without air. She handsmothers him several times, using different poses. She holds his breath for long time, without mercy.
