One day, when a deliveryman went to deliver a package to a valued client's house, he was greeted by a married woman in provocative attire. Every time he goes there, the wife tempts him with her lascivious looks. (Bath towel, wet and see through white T-shirts, swimsuit, bunny girl cosplay, etc.)

Then... one day, she greets him in the nude, and he finally gives in to temptation. They have adulterous sex in the entrance way. "My hubby's away on a business trip... so please come see me again." she says.

From that day forth, infatuated with the wife, the deliveryman repeatedly visits her room for sex... all the while oblivious to the fact that it is all~ being secretly filmed by a surveillance camera.
