One thing to remember in creating a bunraku girl/guy, despite the cool/neat factor, they will not install any muscle enhancements, bone spurs, and other enhancements that deal out large amounts of damage. This a place that captures persons and uses in them in ways that not permitted in main stream society.
Last thing you want to do is Buff Up Janet/Joe to be able to go one on one with Bubba the Love Troll and win 3 out 4 Falls. This is not captured Fight Club.
Items that make you more "limber etc" would be installed. But the main priority besides the basic installation package is things that aide healing and increase resistance to diseases. Pain can be used to control such girls, so pain reduction devices would not be a high need item to install.
Despite how you currently feel about the aspect and various variations in sexual interests, it does happen today in numbers that most main streamers could not image, so in 70+ years it will be in even larger numbers.
If you think I am blowing smoke, cruise the alt.*.*.erotica.*.* newsgroups note the ones with the most headers/files, cruise the many and varied adult web site pages.
Out of the mainstream sexual interests are on the increase due in part by the Internet, with VR/AR and total wireless, in 2070 it will undergo massive growth beyond what we today can imagine, even by my perverted and sorted imagination.
So does that mean things like Furries and Fluffies will be there in such parlors yes, and in numbers that many here in our time would find distasteful.
The parlors will more than likely have specific sexual interests that most of their girls/guys are equipped to service. That could mean two parlors could be side by side each provided a different sexual interests.
Most of the parlors briefly described in SR, are not dingy, dirty dens of such activities but more clean than alot of places that Runners hang out in.
Get into the mind set up the operator/owners of such places, that will give you more insight as to what gear is installed into a girl/guy. The last thing the owner/operators of such places would want to have a girl/guy is one already equipped with weapons or items that make it hard to control them, or cause injury to staff and clients. It is too easy in the SR world to "create" a girl/guy who does not have such enhancements, so abducting one would not be a high priority.
Most Clients of such establishments are not looking for a mainstream interests nor a "quickie" orally, vaginally or rectally. There are ladies/gents and establishments that easily provide such services well under the costs of a parlor girls/guys.
