I love this site and have found myself sneaking in here more and more often recently. I love seam riding when I am driving, and often put on a pair of blue jeans with a good thick seam, together with the right kind of panties, in order to indulge myself. Once I am out on the open road I get myself settled so that the jeans' seam is perfectly positioned so that all the most sensitive parts of me are riding it. Then by squeezing my legs together and moving gently to and fro I can work up a lovely head of steam. Sometimes it has not been safe for me to continue driving so I have had to stop and finish myself off with my fingers.
