Whereby gentleman fist's his lady's axe wound and once fully inside releases that fist to fully open up all five fingers into the shape of a starfish.
Man, you should've seen the look on my German girlfriend's face when she woke up in the middle of the night to find a russian starfish up her.

I just have a girl a Russian Starfish and she was gasping for air like she was drowning.
