A married woman began her affair by secretly meeting at love hotels or other places while hiding from her husband or girlfriend. Initially, their relationship was purely physical without any emotional attachment. However, over time they grew closer and started meeting just to satisfy their sexual desires. Seeking more thrill, she even kissed her husband before indulging in acts like fellatio and intercourse. They enjoyed their dangerous final fling together until they were caught.

不倫関係の初めの頃は、夫や彼女に隠れてコソコソとラブホなどで逢い引きしたのだが、所詮は身体だけの関係。徐々に関係もなれ親しみ、ただ性的欲求を解消したいがために会うだけとなる。背徳的な刺激を求め、なんと旦那の側でキス。そしてフェラやセックスへと発展し、バレたら最後の危険な火遊びを愉しむのであった。
