Would it be nice if we could bring actions back to the Night life aka: Red Light District.
Only in this area only the “Service Provider” can do the inviting.
Not only could a service provider invite a client “Behind the glass” but…. the area behind the service provider and behind the curtain could be for all of the sex poses.
The curtains could be semi translucent allowing you to get a idea of whats going on without seeing all of the details.
So in other words…
Providers can invite behind the glass to dance or cuddle
Providers can invite behind the curtain for more intimate fun
Just my thoughts.
