Stay in that position, with your arms and legs tied together and sticking in the air.
Let's see how you can beg. Beg me to let you take that dildo out of your ass and put it in your mouth. Beg me for 30 seconds, becoming increasingly desperate.
OK, stay tied and use your ass muscles to push out the dildo.
Once the dildo is out, remain tied but squirm over to wherever the dildo fell out. Use just your mouth to pick up the dildo, making sure that the end that entered your ass is the one entering your mouth. Now suck on it for 30 seconds.
