Bound at the wrists, a submissive kneels before her Mistress, her eyes downcast, her breath coming in short, eager gasps. The Mistress, clad in black leather, runs a gloved finger along the sub's wet slit, drawing a moan from her lips. She pushes her finger inside, feeling the sub's tight, eager cunt clench around her. She adds another finger, curling them upwards, finding that sweet spot that makes the sub writhe with pleasure. The Mistress fucks her roughly, the sound of wet fingers slapping against wet pussy filling the room. The sub's moans grow louder, her body tensing as she nears her peak. With a final thrust, the Mistress sends her over the edge, her pussy squirting, her body convulsing with pleasure.
