The main feature I'm looking for tonight is simple: I am devoted prey and you are a supernatural being who drains me. Personally I am transmasc (bonus hole boy), but what parts I have are up to your tastes.

Here's a possible example:

I've been contracted for a job at this old estate. Everyone tells ghosts stories about it but you seem nice enough. Hell, you're pretty sexy and I joke that I wouldn't mind if you were a bloodthirsty vampire. You're so strong and enjoying teasing me. I'm easily flustered but my body naturally wants to lean into your hands when you grab me. When your lips and teeth finally meet my throat I have a moment of panic before realizing this is the best thing I've ever experienced. Instead of fully killing me, you make me into a thrall. I live, but only for you. If you choose to be cruel you can take a knife to me, choke me, kick me, parade me around others for service, and as long as it pleases you I'll love it. Now I live as a free use blood bag and sex doll who helps lure in more disposable prey. I love serving you but there's an ache inside me that deepens every time I watch someone else give you their final drop. Please Master/Mistress, when will I be good enough? How can I please you more?

Other variations could include a literal machine milking out sexual fluids and life essence, flesh based cannibalism with guro/body horror, me convinced your samples and such are for science, you are my god, etc. I think a succubus/incubus wouldn't be quite as fun because I want you to consume me in more than just the sexual. Your own ideas are very welcome.

I'd love to lose my mind and my humanity for you, maybe even becoming physically unrecognizable. Of course my character will long for snuff but whether you grant it is up to you. I'm open to a longer story where we build to it.

Kinks can include but not required: hypnosis, slave, pet play, freeuse, dubcon, violence and gore, size difference, gaping, humiliation, public, TPE, hyperspermia, inhuman partner and shape, torture, worship, extreme body mod, snuff, cuckolding, knotting, medical, fearplay, sharp things, breath play, probs more, just ask.

Limits: pregnancy/talk of breeding and associated terms, scat, analingus, kids, misgendering, body shaming
