Asian Rotary 

When a man bangs a group of Asians chanting in Japanese, while dancing in a circle. He usually gets 5 seconds, per Asian. The Asian who he cums in gets spanked. Another name for this is Asian Hot Potato.

I tried an Asian Rotary last night. The Asian who won ended up being my brothers sister in law. SHE WAS TIGHT.

A torture device once used as a punishment for those who have commited a crime. It fits onto one's penis or vagina, and then is twisted, via a motor, to violently to cause aggonizing pain.

It's a torture device, does it really need an example?
