I'd hate to be stuck out here all alone. Do you know how to change a tire?" Sure, no problem", I said with a grin. So, about 20 minutes later the job ...was done and I stood up to wipe my hands. She moved up real close to me and said with a sexy smile, "I really want to thank you."I smiled back and said, "Oh, that's Ok, I'm glad I could help out."
