A body that trembles, desires, and devours. "There may still be a lot of eroticism sleeping inside of her..." says Aimi Yoshikawa, who has a provocative body with an artistic waist and fair H cup. In order to awaken the "instinctual eroticism" that may still be hidden within her, she is brought to orgasm again and again, her body is distorted by a succession of pleasures, and she is awakened after squirting and convulsing, in the development and training of her convulsive body. Two stories are included: "Convulsive Body Squirting Instinct Mating," in which she orgasms multiple times while having sex with a man, and "Pleasurable Body Lewd Mouth Service Cumshot," in which she is rewarded for taking a dick deep in her throat and receiving a blast of cum on her face.
