To earn money for living expenses, a woman is dominated by men in the shopping district, forced to wear a collar and subjected to various humiliating acts. Each time, her pussy gushes with lewd fluids, her body no longer her own. Witnessing her degraded state, her son can no longer suppress the forbidden urges he has kept hidden in his heart, and finally surrenders to his mother. This taboo mother-son union forges a new bond between them, driving their desires higher and leading them deeper into madness.
