My sister-in-law and I have been having lots of fun this Christmas trip but when the opportunity came to go shopping with just her for some public play I could not resist. We went to the local outdoor mall dressed in cute dresses and flirting the whole drive there in front of our Uber driver. When we got there I openly kissed her (the first time we've done that this trip, since her family doesn't know about our relationship) and she tasted so good. She melts when I kiss her and I love it. We were picking out clothes to try on and we went into the dressing room. As soon as the door was locked she was on her knees and I had my leg hiked up. She peeled my wet panties down and went straight to work on eating me to a leg quivering orgasm.

We paid for some purchases as I was flush from my orgasm and I flirted with the sales girl who was probably a bit younger than my SIL. I teased my SIL after we left about it. Asking if I should go get her number, does she wanna watch me make that young girl cum, etc. My SIL got so worked up by that she held me close and kissed me deeply. She like being my little girl and doesn't wanna share me lol.
