HAWA-311 Misaki, a 30-year-old frustrated wife who likes the cowgirl position, is given a condom to an ordinary college student's home and is not satisfied with the one-night rubber sex session, so she allows him to cum twice during her stay.

Misaki, a married woman who applied due to lack of sex between her husband and wife, was given a condom and decided to spend the night at a university student's house. She quickly finishes sex using a rubber, but she allows him to have sex without a rubber because he is not satisfied with ejaculating once. The two decide to pretend that the second time they had sex never happened, but they can't forget the raw pleasure, and as the time approaches for them to go home, they seek each other out again.
