Sometimes I find it really appealing reading and asking others about their RP scenarios, asking how they experienced the situation. So i thought this could be a plotline on its own.
Instead of playing a scenario first person, the setting could be: you invent a past-time vore incident and your rp-partner can ask questions about it.
So, for example, you can play it as a confession: you confess that you have eaten a person dear to your rp partner. maybe the pred can play a reluctant or unreliable narrator.
The charming aspect is that both players have equal possibilites to maneuver into a direction of interest.
If this idea is an old hat, ignore it
If not i shall call it "voration" or "hotseat" or vore Q and A.... you name it
