An innocent 18-year-old beauty. A young pervert who has just awakened to sex has come to the secret realm of sex. She only has physical relations with family members, and her sexual desire explodes all at once with an older man. She swallows semen and performs deep throating to a level that would make adults cringe. The initial impulses of an 18-year-old who has just awakened to sex are incredible, and she is Kokoro enough to even try abnormal play. She has sex with a relative and makes him cum inside her without any regard for him, and then she swings her hips vigorously to enjoy the pleasure. This 18-year-old is abnormally perverted.
