Keiko met her during a barbecue with a friend, who introduced her to a woman looking for sex. The woman already had a boyfriend but was seeking someone to satisfy her desires, as she rarely had relations with her husband and usually relied on a fuck buddy. At the time, she had no one and was feeling unfulfilled. Keiko had slept with her once before, but due to time constraints, they couldn't fully enjoy themselves. Yet Keiko was captivated by the woman's sensitive body and couldn't forget her.
