Dual Action Strap 

Double sided dildo inserted the various orifices of two sexual partners.

Why's there a double sided dildo in your bathtub?

Because a dual action strap is the best way for switches to fuck because they can top or bottom with every stroke.

Dual fist action 

Dual fist action refers to rubbing the meat with both hands. Generally speaking if you can fit both hands on your dick it is very large.

Will: I get that dual fist action on every night.
Kyle: I can only get that single fist action.
