I have this fantasy every so often about the sluttiest "chastity" scenario. In it I'm stuffed full of any toy, preferably on the large side, in both holes and am then strapped into a chastity belt. Its loose enough on me that whenever I sit or stand or even walk the toys slide slight out and then back in again.

After the toys are locked in (with a lock I have no key to) I'm told to put on a little dress and some heeled shoes. No bra, no panties. Then I'm sent off to run some errands in public which jostle the toys around inside me so much. Within 20 minutes I'm dripping down my thighs and practically bending over begging someone to just touch me however they want if they can get me to cum.
