Brothels are kind of my jam. Have a list of 13 quick character concepts for hookers, whores, and courtesans: feel free to build on anything here. If the species isn't mentioned, it's not important.
Aya
A golden-furred Huline who's been in the business for centuries. Ridiculously skilled in bed, but doesn't give a shit about her clients anymore: has an enormous amount of credits saved up from her job, which she never spends on anything. Very 'ara ara', treats everybody as if they're children. (Because they are, to her.) Basically continuing as a courtesan out of habit and wishing that something interesting would happen in her life. (Of course, this would only happen if Huline make it in, but CoC gave me a massive Kitsune fetish, so...)
Central Kinks: Tail Play, Petplay, Distracted Sex
Cheri
A total exhibitionist slut, Cheri is working her dream job as a stripper and whore. She spends most of her pay on keeping her tanned, athletic body in tip-top shape with the latest gene-mods: while she looks human, her actual genetic makeup at this point comes from too many species to count. Gregarious and easygoing, she loves sharing her body with anyone who wants it.
Central Kinks: Exhibitionism, Group Play
Sarah
The new girl at the brothel, Sarah came of age only six months ago. While she's an relatively inexperienced virgin, she makes up for her lack of skill with infectious enthusiasm. Often, she can be found arguing with the owners to try and get them to lower the astronomical fee they're charging for her virginity: in the meantime, she serves clients with her mouth and ass, wearing a chastity belt so nobody gets any ideas.
Central Kinks: Virginity, Anal, Chastity
Tasha
The 'dragon-girl' nicknamed Tasha is from a coldblooded alien species, who have a language that normal translators can't handle. Unfortunately, her own specialized translator is broken. Fortunately, prostitution is a job where you don't need to talk much.
Oddly, she totally refuses to take any of the money she earns, instead living off the considerable stores aboard her ship. It's possible she thinks prostitution is some kind of alien dating service.
Kinks: Cuddling, Romance, Heatplay
Renee
The spoiled daughter of a wealthy business-owner, Renee hooks more for fun than for the money. Her insatiable libido drives her to fuck around the clock, sometimes even showing up on a new client's doorstep with her previous client's load still deep inside her. (Wait, isn't this someone we know...? Never mind. :3)
Kinks: Group Sex, Sloppy Seconds
Adam
After five years as the bartender, Adam made the transition to being a full gigolo with remarkable smoothness. Between his 'personal charm' and sculpted body, he's a real hit with the ladies. He's firmly straight, though.
Kinks: Seduction, Hair Pulling
Alisha
Alisha is a Vanae woman who was kidnapped from M'henga by slavers. Unfortunately for them, she proved to be a much better at fighting when she wasn't being stunned down by a tiny drone from long range. Now a free woman, she works as a prostitute in order to fulfill her race's unusual semen-dependent diet. Since she also refuses any form of birth control, she's almost always pregnant as well.
Kinks: Breeding, Pregnancy
Alanna
A heavily-modded, satyrine courtesan, Alanna enjoys knowing her place - which is superior to everyone else, naturally. She reluctantly agrees to accept money in exchange for minor sexual favours, mostly because she enjoys watching people begging her on their knees. The brothel makes her clients sign waivers before entering her room.
Kinks: Sadism, Orgasm Control
Ashley
Ashley has always wanted to have the girl's body she was denied at birth: not content with the illegal mods common to the asteroid, she's turned to prostitution in order to cover the best genetic treatments available. While she's a little awkward due to underlying insecurity in her womanhood, it also means she always puts 110% effort towards her appearance and her job. (Yes, I realize we already have Embry, but I don't see this as a significant argument against having additional trans characters.)
Kinks: Trans/Crossdressing
Samantha
A college student studying creative writing, Samantha takes clients as a side job to help with her student loans. Warm and welcoming, she has a girl-next-door charm that makes her easy to relate to.
Kinks: Vanilla Sex, Condoms
Gale
Raskvel gal Gale loves partners who are bigger than her. That, and money. Prostitution was a natural job choice. Despite her eagerness, she sometimes puts off her clients by treating them as merely cocks she owns. Whatever you do, do not ask to see her sex toy collection.
Kinks: Ownership, Sizeplay, Sex Machines
Ipsea
Ipsea is the brothel's resident Venus Pitcher, a skillful hypnotist who managed to convince one of her offworld lovers to transplant her. In a cruel twist of fate, she germinated with a deep wanderlust driving her to see the stars. The brothel, with its frequent offworld visitors, is the closest she can manage, cursed as she is with roots instead of feet.
Kinks: Bondage, Hypnosis
Shannon
Shannon works hard all week at her dead-end job, then comes in on the weekends with a pack of cigarettes and a bottle of whiskey and fucks everyone in sight. Maybe a career in prostitution will turn her life around, but she doubts it. More likely, she'll just end up dragging more people into the mess her life's become.
Kinks: Purification/Corruption
