Anonymous and exhilarated, she kneels, her breath fogging the partition. A massive, veined black cock appears, throbbing with anticipation. She licks her lips, eager to taste the taboo, and takes it deep, feeling it stretch her mouth. Her husband's grunts echo from the other side, oblivious to her secret pleasure. She sucks enthusiastically, her body aching for more, as the stranger's cock pulses, ready to unleash its load into her waiting mouth.
