Birth of the Busty Oppai Dragon (Patreon)

One day while visiting Gremory mansion, Issei sees a book of forbidden spells. He asks what each one does, finds one that catches his attention, and comes up with a more interesting way to use it...

Hello everyone, I hope you like it!! What other aspects could Issei steal? 🤔Thank you for your suggestions!! The titles were funny hehe
