Not So Mainstream
Let’s discuss for a brief moment the typical sex furniture such as a special chaise that has latches and loops at the base of the furniture piece where one might lock a ribbon, cord, string or belt from a wrist or ankle restraint to hold a partner in specific assumed position where they really have no way to move out of that position except by moving the entire piece of furniture. This form of sensory deprivation can make sex life very exciting and wild even. There are so many positions one could be strapped into for maintaining positions.

Definitely NOT Mainstream Yet Interesting
Certain sex machines are scary at first glance yet then again I guess it depends on how horny you are. On that note, it surely depends also upon WHOM you are. I’m sure some men and women can look at specific sex machines and bust a nut immediately! Original or black label for sex furniture, and Russell Brand known by its many descriptions for a sex machine are all hot!
