My background:

I, M21, am dating an F19. We have met up with another guy off Reddit before and are open to threesomes. She’s into exhibition but we don’t have much experience with it.

Fantasy:

I imagine one evening, me and my gf meeting up with someone in their car and driving to an empty(ish) parking lot for us to use her. We’d get her naked and horny and once we finish using her (or before we start), while she’s naked, we grab her clothes and run out of the car with them, dropping them off in a pile somewhere on the other side of the lot.

We’d come back to her frustrated and confused, and her only way to get dressed would be to run across the parking lot naked and grab her clothes before coming back into the car; but we wouldn’t let her back in. We’d lock the doors and watch her as she struggles to put her clothes on worrying that people might be looking from inside their own cars at how much of a slut she is.
