About this work

[Spartan training for a premature ejaculator who can't even last 5 minutes] After arguing with his wife about his premature ejaculation, they became sexless and his pent-up cock is about to explode. One day his sister-in-law Kanna stays over. The exact opposite of his wife — big breasts and a curvy, sexy body — he gets instantly erect. He was secretly masturbating but Kanna caught him... However, Kanna says with enticing touches, "If you can hold this for 5 minutes I'll have sex with you." Thus begins an intensive bootcamp to strengthen his premature cock — but if his wife finds out, it's over.
