Which toys are right for doubles?

San Antonio, thought I'd make an attempt to know more about how ya'll prefer doubles. So my questions is:
Ladies whats your favorite toy when partaking in a double's session?
or
What toy are you curious about using for a doubles session?

Gents what toy do you or would you prefer to see the girls use on each other.....or on yourself if that's your thing?

Hope to hear some interesting answers
