Behind the gloryhole, a black cock throbs in anticipation. The mysterious woman on the other side slips her tongue out, licking her lips in anticipation. She takes the head of the cock into her mouth, her warm, wet lips enveloping it, sucking gently. She sinks down, taking more of the shaft, her tongue pressing against the sensitive underside. She pulls back, her lips making a popping sound as she releases the cock, only to dive back in, taking it deeper each time. The rhythm picks up, her head bobbing faster, her hand working the base of the cock in sync with her mouth. The mystery cock pulses, ready to explode, but the vixen is nowhere near done.
