OOHH lucky you! I think she seems to like to tease others, flirt, and show off. Enjoy it and hope she keeps up the good work, maybe some juicy texts/sexts if you can find them, let her have fun but enjoy being sneaky haha
Me and my exgf used to go for "fun weekends" on various caravan sites. Mostly exhibitionism flashing delivery guys or leaving curtains open on the van. We had some good results and she loved the attention
