DnD Sex Edition

Doppelgangers are vaguely humanoid creatures that can shift their form to match any humanoid. While they are often solitary creatures or live in very small groups, they may use humans to assist with mating, allowing any child to grow up as a fey changeling. Doppelgangers prefer to infiltrate societies of progressive complexity as they age rather than build a society of their own. If using doppelgangers as an enemy, this could be a younger one just starting to integrate into human society. The presence of one doppelganger does not preclude the presence of others, after all.

The townsfolk may be worried about the rumored doppelganger nearby, but you are most certainly not. All you can think about is what it would be like to be with such a creature. Would they retain their real form? Would they shift forms with each position change? Would their perfect mimicry slip when they experienced the mind-altering orgasm you could deliver? You wander through the darkened streets, working yourself into a feverish lust just thinking about it. You pass by open windows of houses and hear snippets of tense conversations. “I just think the mayor was acting a bit odd, is all! Not like himself!” “I’ve told you, I’m me! How am I supposed to prove it to you?”

These poor people. Don’t they recognize what an opportunity they have walking among them? You might have to just sleep with the whole town and then you certainly check off doppelgangers. Probably. If there really is one here. 

A door opens, casting light onto the street before you, and a figure slips out of a small tavern. The tavern serving wench you were flirting with last night. Or maybe it was the last time you were passing through this town. She’s a pretty one with a pert little smile. She’s carrying a bundle and startles when she nearly runs you down, clearly leaving for the night. 

“Oh, I didn’t see you there, handsome! Weren’t you supposed to be waiting here for me last night?” She giggles, wrinkling her nose at you. 

Performance check to determine if the PC can seduce with the human serving wench (DC 10). 

On a success: She giggles again at your excuses for standing her up. “Well, come on then. I live just around the way.” You follow her gamely back to her simple flat above a nearby storefront. She’s a bit boring in bed, sticking to the basics. Not quite a virgin, but clearly not matching up with what her flirtations promised. It’s almost as though she had spent more time learning how to flirt than how to fuck. By the time you leave town, you barely remember the passably enjoyable evening.

Opposed Perception/Insight check to doppelganger’s bluff/deception to determine if the PC learns they slept with the shapechanger.

On a fail: She frowns at your excuses for standing her up. “Guess it wasn’t in the cards for us.” She holds her bundle tightly against her body and walks quickly out of sight, towards the town gate.

Opposed Perception/Insight check to doppelganger’s bluff/deception to determine if the PC realizes this may have been the shapechanger leaving town.
