Give her another fetish

You can't get over how hot Christina looks with cum drying on her tits, which are spilling out. "Power off."

She blinks a few times then gets up. "Damn, I loved that!"

You put her back into a trance. "Christina, you love cum on you; in fact, you crave cum on you. Until you turn 50, you will be addicted to men half your age cumming on you. When you leave here, you will be on a quest for cum. You need to give two more titty fucks and have those guys cum on your tits. You also need three guys to cum on your face, another to cum on the right side of your head, another on the left, another on the top, and one to rub his cock up against the back of your head until he cums. Do whatever it takes to get that many guys to cum on you. You'll massage the cum through your hair. After all of that, you will go home, strip to your panties and go straight to bed. Got all of that?"

She nods.

"When you wake up, you will immediately video call me. Oh, any time a guy cums on you, you orgasm. You want to show off all of the dried cum and brag about it. Once a month until you turn 50, you'll need to be coated in cum."

You snap Christina out of her trance and send her on her way. As you watch her saunter out, you think about how the next time you two meet, you're going to spank and fuck that ass.

An hour later, another hot celebrity is ready to be entranced.
