Don`t Toy With Me, Miss Nagatoro, volume 6

It's a battle of the brushes! The president of the Art Club has challenged Senpai to an art competition, and if Senpai loses, his precious club will be no more. Nagatoro and her friends also have skin in the game since they'll be losing the one place where they can torture Senpai without interruption, but do they stand a chance against the club president's talent and her erotic assault on the senses?
