such an interesting device...

It looks like a see-saw and a dildo...combined.

"see-saw dildo"
"dildo see-saw"
"see-sawing dildo"
"dildoing see-saw"
...

And in the lower left, is that the other half of the see-saw? And, if so, why doesn't that other half also have a dildo? And what are the two red ball things along the bottom of the picture?

whats holding her up, if no one's on the other side?

She has to force the other side down. That's the fun in it.

unless someone on her side is pulling her up no?
