Packings?

Has anyone heard of this?

I had an acquaintance who told me he took sterile rubber sheeting and would tightly 'pack' his playmates vagina's. Then he had them put on a belt and attach a wide rubber strap that passed through the legs and fit tightly across the labia. He and his playmate would then go out and do something for a couple of hours (dinner, cafe, park..)

The real exam would begin once they returned home.

Sounds reasonable... for enthusiastic med fetish / rubber fetish fans. An inflatable plug or panties with a plug/toy might do the trick to and be a bit easier.
