DnD Sex Edition

Wraiths are incorporeal undead creatures known for their hatred of the living. Seducing one would therefore be a bit tricky. They cannot be touched, even if they can occupy the same space, and the only sex they’ll be interested in is possibly hate sex. They don’t mate as much as they just make more of their kind by draining the living and transforming them into a wraith, essentially making them incorporeal vampires.

The shadows shift oddly, as though there is a nearby flickering candle, despite the darkness of the ruins. Two glowing red eyes assess you, taking stock of the veracity of your carnal offer. The voice that arises from the depths of darkness glides along your skin like a winter draft. “You are yet living, yet you offer me a taste of your vitality?” The shadows ripple like a fluttering cloak and abruptly the red glowing eyes are over your left shoulder. “I hate you,” the creature states baldly. “You are pathetic. Dependent on food, water, light, a physical corpse!” The wraith’s voice echoes into the darkness as it grows louder with each declaration. 

Performance check to see if the PC can have hate sex with the wraith (DC 10).

On a success: Shadowy tendrils pass through your breeches and wrap your cock in an odd icy and hot tingling sensation. It’s not unlike the numbing cream the clerics sometimes use on aching muscles. Hastily, you undo your trousers and thrust your hardened member into the pool of darkened shadow, following that odd sensation. You withdraw mostly to normal air before thrusting forward again. Frustratingly, there is no friction. The head of your cock is starting to lose feeling as the burning numbness takes hold and begins to spread.

5e: PC takes 4d8+3 necrotic damage and must succeed on a DC 14 Constitution saving throw or its hit point maximum is reduced by an amount equal to the damage taken.

Pathfinder: PC takes 1d6 Constitution drain DC 17 Fortitude negates.

The wraith laughs with malevolent joy. “Yes, touch me. Use me. Fuck me. And when you are done, I will remain and you will join me.” 

Continue until the PC goes down or pulls away to initiate combat.

On a fail: The wraith continues its rant. “Why would I bother fucking you when I can get everthing I want just by touching any part of your mortal flesh? What’s between your legs matters nought when all flesh can succumb to my touch.” The shadows surge forward, blanketing you in darkness. 

Initiate combat with the Wraith getting a surprise round.
