Give her false hope and then crush it again.

You have a sudden vicious idea of how to crush the little creatures hope and mould her into your perfect willing ****. Stepping forward you crouch down next to Jester and raise her face to look up at you, a brief touch of the Reality Marble and an illusion takes hold, your face resembling that of the Traveller and the top half of your black cloak becoming dark green. Your memory conjures forth the voice of the Archfey turned God as he bantered with the heroes of the Mighty Nein, at least until it became clear your power was too great.

“Jester...have you so little faith in me? Listen close, I need you to submit to some really awful things to keep up this ruse. I can’t reveal myself as The Traveller yet but you can be sure I will when the time is right. Until then I need you to be strong my foremost cleric and favourite worshipper. No matter what you have to do, can I count on you?”

The expression of hope that overtakes Jester’s face almost makes you burst out laughing. She’s so pure and willing to believe, it’s adorable. She looks around the empty room and whispers up to you, nuzzling against your hand on her face like a cat.

“Oh Traveller! I knew you wouldn’t abandon me. Ok ok I can play along with whatever I need to do! You can count on me!”

I give her a soft smile and a parting wave as the illusion of the traveller fades away to leave your own form in your long dark robes. Rising from a crouch, you undo your trousers and let your long thick cock out, it’s already hard and ready to go.

“****! I command you to pleasure me with your mouth!”

One of your eyes flashes green with another illusion and you give Jester a wink, then a pointed glance down to your crotch.
