A tragedy that strikes an ordinary young wife, Yui! How did it come to this? Yui is being used as a toy by a man other than her husband, right in front of her husband. She shouldn't feel anything, there's no way it would feel good. Contrary to her thoughts, her body reacts sensitively. No, don't touch me there! Pleasure wells up inside her, and she reaches a climax without being able to do anything about it.
