Do S na Seitokaichou-sama ga M Note ni Shihai Saremashita 03 | ドSなマイナ会長サマがMノートに支配されました。 ～ドMに張り合うご奉仕 do S～

Before the main character could subjugate Maina, Shino was already turned into an obedient masochist slave by the M Note’s power. Shino was going to just watch as Maina made the main character cum, but as the main character was about to make Maina his masochist slave, Shino pronounces that she already is a slave. Because there is a law that states there can be only one masochist slave to each master, Souta has to choose between the two, who battle by pleasuring him… Maina is used to reigning as ruler, but she doesn’t skimp on her effort as she gives the main character a boob job and even rides him. However, even that is futile with Shino in the mix. Shino’s gentle and caring fellatio and from behind sex causes Maina to feel a sense of danger… Feeling the biggest threat from someone so close to her, what move will the blonde bitch president take…
