Butt plugs

I often wear a plug under a short skirt and then go out and accidentally reveal it. I was made the other night by a master to wear a dildo out in my ass and go out to a bar. Because it was a dildo it was hard to keep it in and I was not allowed to use my hands to keep it in. Whenever it fell out I was made to pick it up and then in front of anyone who was there give it a suck and put it back in. If it fell out 3 times I had to go to my master and loudly ask for a bigger dildo because the current one was too small.
