This is quite a good one. Preferably for the sub/slave girls...

Lube your anus, work it out a bit then insert the anal plug, balls or any other toy, or a vegetable of your choice, a cucumber fo example, wear your underpants and a skirt or a dress over.

Now comes the good part.

Reset the timer on your cellphone or similar, go out of your home, if possible by public transportation and get to a place with high frequency of people, stay the longest you can. If you are able, meet with a friend/relative for a drink/dinner, try to act the more normal possible.

Get home, take the plug out. Let us know of how long you managed to hold, and your impressions

If you wish, it would be nice to post the pics of what you used and how it looks in your asshole before you get out of the home.

Love,
