I'm too old to wear low cut jeans now. I wore 517 Levis back in the 70's, and my gf(later my wife) thought it was fun to rub me a hard on when we were cruising in my old VW bug. it would come over the top of my jeans by a couple of inches, and she would play with my head under my shirt. we tried this last summer and my head was about even with the top of my jeans, and I have not shrunk. so the jeans now have more rise in them than back then. wife's a little bolder now, when it would not go over the top, she unzipped, and gave me a nice bj while i'm driving down a rural road. the guy behind me, honked his horn, when she popped up in the seat next to me. he thought he was following a single occupant vehicle. ha ha ha!!!
