You can add Lady Malice to your list of dommes (Mistress Montana, Mistress Daria) who have the experience to play with sounds. And, of course, the lovely Ms Lacey.
I've only observed that type of play... having things shoved in my cock just makes me say "RED!FUCKINGREDREDREDREDOHMYGO DRED!". Or the "MPHHED!" equivalent if gagged.
If sounds is something you DO want to do, purchasing your own set is the way to go. While I do know many Mistresses who are very, very anal about sterlizing and such, for any toy that penetrates your body and that you can't put a cover on, its best to provide your own. If you do a bit of research you should be able to find a sounds set for around $100 or less.
