A married man with a family takes his O-cup mistress on a secret trip. Desperate to make up for all the time they have spent apart, they begin passionately making out the moment they arrive and refuse to stop. They play in a private bath, experiment with bondage in a yukata, and push her through repeated orgasms until both of their desires explode. Their intimate first-person affair continues through the night and ends with raw sex and a creampie.
