Neighbor's daughter secret exposed, do you keep it or leak it?

I guess this is more of a guy’s question, you are out about town celebrating a person you know bachelor party. Some of the group gets the ideal of going to a strip club and you reluctantly tag along. The 4th girl on the stage you think you know as a neighbor’s 17yr old daughter; then she moves to your end of the stage and your eyes lock and by her very surprised and shocked looked she is. She fumbles through the rest of her set and quickly comes from the back and beckons you aside (to the whooping of the crowd you are with thinking you are getting lucky) She begs you not to give her up to her parents or tell the club owner. You discover she got the gig with a fake I.D. and her parents think she spend that time (3 times a week) at the library or friend’s (which also strips) house doing AP studies. What do you do? Or is it such a land mine you just leave and purge it from your mind you even knew it happened?
