Three years into marriage, young wife Ayumi is a stunning beauty with refined features, captivating everyone she meets. She currently works at the reception desk of a famous department store. Initially, she was forced to sleep with acquaintances to repay her husband's debts. Since then, she has been under her husband's complete control, trained and treated as a mere sex toy. During sex, she writhes uncontrollably, transforming into a completely different person—lewd and depraved in her behavior. To make matters worse, she has become pregnant by another man, trapped in a humiliating and desperate situation.
