Mayu is a carnivorous G-cup beauty who makes her home in Shibuya. Though she appears to be an ordinary office lady, her eyes are always searching for a cock to prey on. The moment she sets her sights on her target, her seduction begins, captivating the man with her "real puff puff" technique, using her G-cup breasts as a weapon. Once she enters the hotel, she has her own stage. This is a record of raw sex by a modern succubus who is particular about the raw feel and milks men dry with her wild thrusts.
