Demonic power struggle

[Panakananana]

You are a female new recruit as a royal knight, I would play as your instructor, also female. My character dies, or knocked out as we attempt to kill an ancient demon. The demon overpowers both of us, you should fight back as much as possible, then it toys with you and fucks you, you think that if you get him to cum enough times he will be in a weakened state and you can kill him.
If this sounds like something, pm me. I'm open to suggestions too.
