In my free time, I've been working on this XToys tease to have different scenarios with a fuck machine. There's a lube launcher to simulate guys cumming, and technically an estim (if I had one) could simulate spanking. But most importantly it supports audio clips, pictures, links to videos and speech recognition (you say "Fuck me Daddy" and it can increase the variable of excitement and/or do things like spank you, increase speed of the fuck machine, etc.

My goal is to have a rudimentary game where you're working at a brothel servicing multiple men, unlocking access to scenes depending on how well you do in each, where they're different dynamics (like one where you play a 1950s housewife to a bunch of men and they all have commanding verbal phrases while you get fucked, or one where you're at a sperm clinic so the lube shooter fires more shots, etc.)

So far I have:
T1 - Rookie. So the entry level where you're being fucked by virgins
T1 - Frat. A lot of rowdy college guys.
T1 - Wife. 1950s dutiful wife scenario
T2 - Sperm Clinic. Way more cum
T2 - Daddy. A lot of older guys
T2 - Locker-Room. Jocks with a cheerleader
T2 - Masquerade. Fucking anonymously by men in masks
T3 - Dungeon. Very forceful gangbang.
T3 - Executive Stress Relief. Lots of very dominant guys with an intern
T3 - Feral. Wolves.
T4 - Auction. Rotating guys bidding on doing different things to you.
T4 - Black Card. No stopping or breaks.
T4 - Couples Therapy. Men fuck you while their wives watch
T5 - Brothel Show. The head of the brothel makes a display of you
