Why not just tell your girlfriends that you are into this and see if they would be ok with you "borrowing" the undies? Hey, if you replace it with new lingerie they may be cool with it. It seems like a harmless kink.

The only thing that might be an issue is that you are doing this on the sly. Your partner may not appreciate finding her stuff , um, used.It seems disrespectful. Asking would be a totally different story.

Also, having partners that play head games isn't going to help your situation.
Sounds dorky, but honesty and mutual respect in relationships will bring you more of what you want. Just be honest. They may like your kink.
