The first time we saw a Sybian was at a kink party. After a few drinks and some encouragement my wife tried it. The orgasm was definitely good, but the exhibition factor of being in a room full of kinky partying people was very elevating to the experience (for both of us) despite the fact she pretty much lost track of her surroundings as the vibrations increased.
With many people taking turns, the machine was wrapped in shrink wrap with a fresh condom between each "rider". They had an industrial shrink wrap roll on a stick like one would use to wrap pallets, worked great.
I bought one shortly thereafter, along with a number of attachments and a Pelican case for traveling. All in close to $1500. If you count the number of times we've used it we are probably close to $50 per ride! I remember one night we had Sybian races at a party, someone else brought one so there were two of them side by side. That was a sight.
It was a great novelty at parties - at first, but eventually with the same crowd it got declining use to the point we stopped traveling with it. We pull it out at home once and a while when the mood strikes, she can sometimes work up a full body sweat ending in great climaxes, but in the end a Hitachi magic wand is the go-to for convenience.
