I would have walked up to him and told him I heard a “clean up” was needed on that aisle, then immediately dropped to my knees and bury my face in his crotch, in hopes of him unzipping and letting me give his cock and balls a tongue bath.
If i would have seen Him getting turned on and grabbing Himself like that i would have walked over to the aisle He was in and done my best to make it obvious to Him that i was looking at His Crotch. i crave having some Mature Old Men catch me looking at Their Crotches and have Them get me to go somewhere private with Them where They could have Their way with me.
I love this classic video! I would have unzipped and let him cum in my pants because I always wear dark pants at an adult bookstore or sexshop. The telltale signs are less noticeable. 😇
