Tiefling X human painter outline

*Tiefling girl does not know her fiendish bloodline, is kind at heart but struggles with powerful urges.
*Namely to devour people whole and cruelly dominate them.
*Living on the streets, she is a tough unarmed fighter, but has killed only once, when she was young. A thug tried to rape her, and she swallowed and digested him in self defense. The episode haunts her to this day, and is one of the strongest things keeping her from abusing her powers.

*The painter is a young man. He also lives alone, hand-to-mouth, as his parents in the Hive disowned him when he refused to carry on the family business in order to follow his passion.
*He has made some bad decisions/deals getting himself to where he currently is, and they might be catching up to him soon.
*Though he is a talented painter, he lacks real inspiration, and his art has been unsuccessful because he finds himself always imitating another style or concept, unable to make something that's really his own.

*When they first meet, the Tiefling is at her regular tavern, schooling the semi-drunk patrons in fisticuffs to blow off some steam. The painter comes in, tries to order some food as discreetly as possible, and wait out the night in the corner of the bar. He's trying to lay low because some guys showed up for "collections" at the flophouse where he usually stays.
*When the Tiefling sees him, timidly and awkwardly trying to blend in to the tavern she knows she has to have him, and breaks off fighting to see if she can seduce him and have her way with him (she does this from time to time, eating strangers as a one-night-stand. But she doesn't play for keeps, she lets everyone go eventually.)
*The tall, muscular, and seductive tiefling is a lot more woman than the small and waif-like painter can handle. Pretty soon they're out behind the tavern and she's swallowing him up.
*The whole experience is divine (for her) and she actually has such a great time teasing the poor painter in her belly, savoring his struggles, that she forgets to let him out before falling asleep in her room at the tavern!
*When she wakes up and remembers what she's done she is horrified... Until she realizes on further inspection that he's still alive inside her. Still, she has some awkward explaining to do when she does eventually let him out. She prepares to release him to go their separate ways when the collection men show up at the tavern, wondering where the painter is.
*Quickly the Tiefling and painter hash out a plan: she will hide him in her belly and pretend to have digested and killed him, effectively feigning his death and solving his debt... And in return he becomes her belly slave/toy for the foreseeable future. The rest is history.

Other notes:
*The story will be set in Sigil, in the Hive
*names/apppearances are always WIP, but the Tiefling is taller than 6 feet, athletically built AND very well endowed from her vore-succubus heritage. Though she is very beautiful, she usually wears simple clothes, with her black hair cut around chin-length. She favors intimidation to get what she wants from people, and has a gruff, masculine demeanor, though she knows how to act feminine and seductive instictively, because again, vore-succubus. Also her tongue is really fucking long.
*The painter is small and slight, probably 5'5"/115lbs. He has thin blonde hair, and is handsome, but very young-looking. He is actually a few years older than the Tiefling (like 24 to her 19), but looks like a boy compared to her. Disowned by his family for pursuing painting instead of the family business of tanning, he has been living in poverty trying to sell his art unsuccessfully for a few years now. He is shy around most people, but intensely passionate about his art, and it's one of the few things he will readily talk about.
