Yui, a lonely married woman with no children and her husband on a business trip, seduces a man who comes to deliver her a package through a delivery service! She shows off her cleavage through her knit top, knowing it's wrong, but she wants to be embraced, so she makes the delivery man carry the package to the back of the room and plans to do something lewd. She touches a man for the first time in a while, experiences the joy of being desired as a woman, and devours each other instinctively... She gets her pussy, which her husband can't satisfy, wet and gets his hard cock pounding it deep inside! Pound! She's so pleased to be pounded! At the end, she gets his sperm poured into her instead of her husband, and she's happy to get pregnant!
