Inserting an exact replica of your cock into your woman's ass while your own cock is inserted in her vagina, or vice versa.
Dude... I bought this penis casting kit and made a latex replica of my unit. Then the other night when I was f**king Carrie from behind, I lubed it up and slid it in her ass. Totally DuoTang'ed her.
