Okay slut, now I want you to get on your knees and suck on a dildo.
Suck it softly at first, with just your lips and tongue, and then progress to moving your entire mouth backwards and forwards on it. After that, deepthroat it a few times.
Continue until you've gagged at least 5 times. Then I want you to look at the dildo and say - with a bit more sincerity than last time - 'I love sucking your cock like the filthy slut I am'.
