Double ended accordian

When two men simultaneously please eachother, while touching tips.

dwarven accordian

A sex position in which one short individual is penetrated through their mouth and lifted by their legs. The larger individual then proceeds to squeeze the smaller person by thrusting their penis down the throat.

I picked up Allie and fucked her in the Dwarven Accordian.
