I, who is usually an honor student, have a stupid junior named Iruma Azuki whose grades never improve no matter how many times I teach her. She always begs me to help her study before a test but I refuse her request because I don't want to waste my time on pointlessly tutoring her because her grades aren't improving... But I end up accepting her request.... She's an idiot but her titjob with her big tits easily destroys my reason... I'm usually rational but I'm being teased by the cheeky and stupid junior and my mind is melted by her titjob...
