Take her somewhere private

You decide to listen to reason and, lucky for you, Hex Maniac knows a place where hardly anyone goes, unless they were people like Hex Maniac searching for Ghost-Types.

"Follow, slut." The Hex Maniac commands.

"Yes, mistress," Jenny says quietly. You notice Officer Jenny is no longer staring ahead like a zombie, as she did just a moment ago. Now that the pendulum has been put away, and Hex Maniac has gotten her riled up, she seems to be staring at you with hungry eyes, as she follows her secondary trainer.

"This way, master," Hex Maniac says, putting her cum-stained sweater back on, "When we get there, you'll be able to do whatever you want with us, and have no one to interrupt."

The purple-haired witch leads you Jenny down a different back alley than the one you started off in. The sunlight doesn't glitter off the semen covering her sweater a moment ago, as the only evidence of semen in her coat are several dark, damp stains. Eventually as the sun gets lower in the sky, you make it to a suburban neighborhood, but calling it "suburban" or a "neighborhood" is too nice. It's desolate, graffiti covering almost every square inch of seemingly every wall. The houses eventually taper off toward the east, but the road continues. Hex Maniac leads you down this lonesome road, toward the sunset. After half an hour of walking, you start to see trees gradually appearing. An hour goes by, and you thank Arceus no cars have driven by here yet. Gradually, the trees turn into a full forest. One that appears awfully dark.
"The locals call it 'Trevenant's Taiga,'" Hex Maniac pipes up, "but we're looking for a specific place in the forest. Not the forest itself." She then points to a three-way intersection.

"This turn is the only road leading to where we're going, master," Hex informs. More walking, and you've finally made it to a cemetery. The road ends at the wrought iron gates.

"Here we are!" Hex Maniac cheers, while opening gates with great enthusiasm, perhaps just as eager as you to fully reprogram Officer Jenny. "And don't worry about any Ghost-Types trying to interrupt you, master. I come here often to commune with the dead, so the ghost-types consider me a 'regular customer,' if you will."

Heading further in, she stops in the middle of the cemetery, where there are very few graves, surprisingly. She grabs Jenny by the hand and stops her in the middle of what you now realize is a massive summoning circle. Hex Maniac then runs back to you, like a mid on Christmas morning.

"Master, now you get to decide how you want to alter her, I know many spells, and am owed favors by many entities.. I know magic that could turn her into a cock-hungry bimbo, an exact copy of me in mind and in her own clothing. Or, I could combine the two and make her into a goth bitch that's super protective of you. If you want, I can even transform her into a futa."
