Teach a trusted follower of the "evil" Tamamo no Mae and her weaknesses

Making a disguise could be fun, but you really want to be dominated as yourself. People should look at you and see you, Tamamo no Mae, the invincible and omnipotent goddess, brought to the floor, holding her pussy lips in pain. There's only one problem. There's not a single person in this village who would hurt you. Every single person, while each with varying degrees of loyalty and honesty, treats you as their god... because... well, you are their god...

"I've got it," you exclaim in excitement.

"Satoshi, heed my call. I summon you."

"Yes, master Tamamo."

Ah, Satoshi. He is your head priest and comes from a family that has faithfully served you for generations. As one of your priests, he is to remain completely chaste. And while your followers think this is because you want purity in your shrine, really you just want to be surrounded by sexually frustrated men. Satoshi is a rather cute and shy man, yet also rather tall. His head reaches all the way up to your breasts, and you often wait at corners so he "accidentally" runs into you. But today, he's going to play a much bigger role than the lucky pervert.

"Welcome in. You may take a seat. I am aware you just recently got this position after your grandfather's sudden passing, so I'm afraid there are some things you need to know. Things that you are to keep completely secret. Not even the village head, your own father, is permitted to know what I am about to speak of."

"Yes, master Tamamo. I will keep what happens here secret until death and forever after."

"....." (This could be a problem.)

"You know how every full moon I close off my shrine to meditate, and absolutely no one may enter or else face divine wrath? You see, I have a secret. In an attempt to remove all evil and impurity from myself, I channeled my powers to forcefully expel those forces. I failed. There can be no yin without yang, and there can be no good without evil. What happened is my evil desires have manifested what could be called an entirely different being—one that I must constantly suppress..."

(Fufu. Satoshi is completely focused and absorbed into my story. The cute young man who tries to hide his perverted gazes is completely missing. Time to break that composure.)

"...and every full moon, the evil bursts back into my body and tries to take over. So I need meditation and complete focus to stay myself. But even then, sometimes I fail, and for a brief moment, I'm not me. So, this is where I need your help. Should I lose myself, I need you to fight me and force the evil back."

"Fight you? But Tamamo, how co—"

"Shhh, it will be fine. I'll be resisting her control. You may not trust yourself, but you do trust me, right?" You say as you put a finger on his lips, only for him to jump back.

"Listen, Satoshi. The other me can't hear what I'm saying right now, but I can feel her intentions. She wants to claim the essence of men using my body to help her regain her strength and control over me. That's why I keep everyone out of the shrine that night. But this time will be different. You will be next to me. But things won't go according to her plan. Lean into her seduction, and then... I need you to hit her where it hurts."

"Using your body in such a way... I will not let her get away with this... but to hit you... even if it's someone else, I'm not sure I can do it... Why don't we get more people?"

(Ever the thoughtful one. Even at the worst possible time.) You are starting to get frustrated by his logical retorts and concerns, but are more than familiar with how easy it is to make a man like this listen to your every demand. But easy doesn't mean painless, and it's not the good kind of pain.

"No, Satoshi! It's because of your pure heart and love for me that I know you can trick my other self. On the surface, you seem weak-willed, weak-hearted, and a man who would give into the temptation of a woman masquerading as your goddess. But deep down, I know you're not like this! I believe you can muster the courage to strike her down. I know you're concerned about hitting me, but I ask you not to worry about my body. It will only be a momentary shock to suppress the other me. If you can't believe in yourself, then believe in the me that believes in you." You painfully speak. Any arousal you had from this situation is completely gone. But Satoshi will now listen to any demand of yours for sure.

"I... I... I'll do it!" Satoshi says after mustering his resolve.

"But what do you mean, 'hit her where it hurts'?"

"Oh, if she's sexually seducing you, it only makes sense to hit her sexual organs. Labia, vulva, clit, breasts... Really, I don't think you are good enough to aim at any spot in particular, so just hit everything in those areas and hope you get lucky."

Before Satoshi gets a chance to speak, you teleport him out of your shrine. You've had enough of conversation and just want to get to the action. And luckily, tomorrow is a full moon. Perfect for the story you just made up.
