Caught in the Hostel

After a fun night out in Berlin, you and your girlfriend Maria are eager to get back to the hostel for some fun. You’re the only ones in the room, so you start making out, before eventually you start to have sex. Suddenly, two Dutch guys walk in while Maria is on top of you. “Oh, sorry, we’ll just drop off our things and go” one of them says. “No, you can stay if you want, I don’t mind if you watch” Maria says with a wicked grin as she continues to ride you. Do you stop her, or do you let her put on a show?
