Swaying in the hot springs, swaying in love—the heart and body of a housewife. Come along on a hot spring journey together. A baby-faced wife, who has been sexless since before her marriage, embarks on an affair trip. After confessing her fetish for the feeling of being dominated, she writhes in ecstasy through cowgirl dry humping, face-fucking, and choking sex, doing exactly as she is told. Recreating erotic memories from her student days, they fondle each other's genitals in a closet, and the housewife moans while moving her hips from below in missionary position. "Your reactions are so fun, I can't help but tease you," she says, showing a sadistic side as she relentlessly plays with his nipples and cock, shouting lewd words while inserting him in cowgirl position. Switching roles, she is pounded hard and reaches climax in tears while being verbally abused about her husband. The next morning, they have sex in the bath while listening to the cries of a bush warbler. She screams about how good it feels deep inside as she climaxes. On the futon, she is pounded so hard she claims she'll break, leading to a simultaneous orgasm.
