Masturbating in Panties With Girlfriend

I have a panty fetish, and I usually wear women's underwear. A few months ago, my girlfriend and I were at my apartment, about to watch movies on the couch, when we decided to both wear tee-shirts and panties while watching the movie.

After a while I noticed my girlfriend's hand slowly rubbing the outside of her panties, and I asked her what she was doing.

'I'm just caressing it,' she said. 'It feels good.'

This, to me, was permission for me to do the same thing, so I began to rub the outside of my panties. Both of us were watching the movie and talking and laughing, while nonchalantly rubbing ourselves.

Then her hand went inside her panties, and she rubbed a little more intently. I did the same thing.

We kept this up for almost three hours, masturbating to the very brink of orgasm but never cumming, until the very end. At the end, we both had amazing orgasms. We masturbate together all the time, and sometimes while we are both wearing panties.
