A sudden tragedy strikes Yui, a new wife who was living a happy marriage. One night my husband came home with a colleague. The colleague was, perhaps, Yui's former dating partner. A husband who gets drunk and falls asleep without knowing such a thing. A colleague takes advantage of Yui's weaknesses and demands Yui's body. In a situation where he can't make a voice, the new wife falls into pleasure without any means to do it.
