Taiichika is asked to try on lingerie at a store run by the wife of her husband's boss, Tabyuchi. Taking advantage of her husband's absence, Tabyuchi forces himself on her under the pretense of giving feedback on the fitting. After that, he repeatedly visits her, raping her whenever her husband passes out drunk or is away on business trips. Subjected to Tabyuchi's relentless advances, Taiichika gradually finds herself overwhelmed by an intoxicating, numbing pleasure she cannot resist.
