Sister Twister 

When you put your dick in your girls ass, and proceed to spin her like a helicopter blade. Doesn't have to be your sister, but it can be. Works best with small girls as they are easier to spin.

I had a dream last night me and Mila were doing the sister twister when my dad walked in.
