You have visited my office, because you crave for my help... You say that you cannot focus on your studies and i have tried a lot of methods, yet you are way too distracted because of your hormones... You are a chronic wanker, you cannot control your wayward penis at all... Firstly i recommend you a psychical chastity cage, but you will pass the idea due you don't want to get permanent changes. So i will recommend you a nice relaxing session, where i will overwrite your senses and mind. I will be the one and only person who has access to your dick... I will put a mental chastity over you and make you become reliant on me... You will be able to cum if i snap with my fingers... You want be able to stroke it, to have sex ever again... Next week i will let you cum again, so you will earn a whole week without any distraction... I am your Mistress from now on. Give in...
