Shino was already converted into an obedient masochist slave by the M Note’s power before the main character could enslave Maina. Shino intended to stand by and watch Maina make the main character cum, but just as the main character was about to make Maina his masochist slave, Shino declares that she is already a slave. Because the law states that each master can only have one masochist slave, Souta must choose between the two, who battle by pleasuring him… Maina is accustomed to ruling, yet she spares no effort in giving the main character a boob job and even riding him. However, with Shino in the mix, even that is futile. Shino’s soft and compassionate fellatio, as well as from behind sex, makes Maina feel threatened… What would the blonde bitch president do when she senses the greatest threat from someone so near to her?
