This is a story about Natsu, who hurts her foot in the track and field club and is massaged by her stepfather using aphrodisiac oil. Her slender body becomes sensitive from the aphrodisiac, leading her to repeatedly climax with intense arching. There are scenes of forced arousal oral sex and toy torture squirting, depicting Natsu losing control as drool, love juices, and squirting flow profusely. However, the final climax may not be necessary, and those who prefer one-on-one sex in full nudity might find it lacking. Nevertheless, the scene where her slender body is thoroughly oiled and humiliated is highly stimulating, providing a sense of satisfaction.
