It is the girl from earlier

It takes a second for your eyes to adjust to the light, but it is quite clearly the girl from earlier. She slowly removes her hand from your mouth, but digs her thumb around in one of your balls as a message to not mess around.

"Who are you?" She whispers antagonisticly, "Where are you from? Where did you get these?" She asks while fondling your clothes.

It clicks in your head - you are wearing mostly modern clothing. Usually you don't have to disguise yourself too much as people just accept you for how you act, but this girl is clearly knowledgeable. Your fabrics won't be invented for centuries, and would be seen as incredibly valuable depending on the time period.

"I... I'm not sure, I just bought them from someone!" you reply frantically, her pinching of your gonad becoming progressively more uncomfortable.

"Liar! Tell me or you lose these!" She growls, raising her voice somewhat.
