Momoe-chan, an active J●, who has only dated one person and has only had sex with that boyfriend. Despite having a bust size of 90 cm and being a huge-breasted girl, she is almost a virgin, which is a waste! To let her know that it's not just about normal sex, let's have her challenge a plan to [bind and fixate her with a vibrator to bring out her sexual preferences]. She is restrained with handcuffs and hemp ropes, and her bountiful chest is also bound with ropes, emphasizing her large breasts and creating a very erotic sight.♪ Just being bound makes her "heart pound," and her love juices begin to soak her panties. After her first experience with bondage, she has her first vibrator. Her abundant love juices serve as lubrication, allowing the vibrator to slide in smoothly. As soon as the vibrator vibrates, Momoe-chan starts trembling and gasping within seconds. To immerse her in further pleasure, an electric massager is also added.♪ Then, the toy is fixed on her panties and left there. Without rest, her vagina is stirred, and in her heavenly state, Momoe-chan is offered a large penis, which she, as expected, wants to "lick." She is also made to experience irrumatio and ejaculation, and unable to hold back, she pleads with moist eyes, "Please put your o●h in my ma●ko." Since she seems to be okay with whatever feels good, a real penis is inserted with a squelching sound. Even after creampie once, her carnal desire does not subside, and she repeatedly begs, "Please thrust more," "Please insert your o●h more," and eventually, she experiences creampie three times in a row. Please watch the main story to see the tumultuous development of the pure and naive J● awakening to masochism.♪
