A weary, married Japanese salaryman, craving sexual release after a long day, retreats to his dimly lit bedroom. With a sigh, he unzips his pants, revealing his hardening cock. He lubes up an artificial vagina, its lifelike texture a poor substitute for the real thing. His strokes become faster, more intense, as he imagines a tight, warm pussy enveloping him. His breath hitches, his body tenses, and with a low groan, he erupts, his semen filling the fake cunt.
