This time, Yumi, a plump married woman, will be taking part in the project where she will spend the night at a university student's house with a condom. Yumi uses up a condom even though she is trampled on by a bigger cock than the man imagined, but that night, she is asked by the man again and is promised to send her out, allowing her to have sex without a condom. The next morning, Yumi seeks sex herself, and despite her rawness, she wants a man to be able to survive.
