I'm looking for someone to play a succubus for a scenario I had in mind

Idea 1: I'm looking for someone to play as a male who is offered immortality in exchange for tending to the lust of a succubus who's had her eye on him

Ideas for how I'd like the succubus to look in both scenarios.

Idea two: I'm looking for someone to play a succubus for a rp idea I had. The idea is that my character had summoned a succubus who instead of sucking out his soul after sex, offers him immortality and her hand in marriage in exchange for him taking care of her constant lust.

( I'm looking for a long-term rp with short fluff scenes in between long sex scenes but I'm fine with just sex scenes or half fluff and half sex.)
