This is the hard part, slave. Now that you've lubricated both toys with your spit, I want you to lubricate your non-dominant hand's four fingers.
Now, shove the dildo back up your ass, and this time I want you to put your forefinger in there AT THE SAME TIME as the dildo.
Once you've managed to widen your sissy asshole enough for this to occur, start fucking yourself with the dildo and the finger at the same time. Make sure you fuck yourself hard, or else you won't be getting my security code.
