Dan was minding his own business riding up the interstate in his pickup truck. He was headed to the nearest town and the hardware for some supplies and a couple of tools he needed back at the cabin. He enjoyed living out in the remote woods, and his wife had become to love it as much as he did, maybe more. Theirs was a simple life, though comfortable, but had become a real routine. There wasn't much variety in their lives. To make it worse, at least for Dan, was that there was no sex life, at all.
His wife was a sweet person, thoughtful and loving, but she'd never been one to care much for sex or making out. Passion was more mental for her. For Dan it was tough, especially when his wife had developed some tumors which had to be removed surgically. They were benign, thankfully, but the combination of her seeming lack of libido with the surgery and medications afterwards resulted in sex being a thing of the past. It simply wasn't comfortable for her anymore, quite painful actually, so theirs was a life of abstinence. Well, if you don't count the times Dan pleasured himself in search of relief. His wife didn't even want to participate in that, felt it dirty and sinful, so he kept that to himself.
Back to the interstate. In all his years of riding the highways on a motorcycle or in a truck Dan had never been flashed so when the red Mustang pulled alongside his truck and rode there he was shocked to see a well endowed brunette riding there with her right breast fully exposed to him. So shocked that he had to look away, think for a moment, then look back to affirm what he'd seen. Sure enough, a nice, plump, fully exposed boob. The girl motioned towards her boob then to her mouth as if to ask if he wanted to taste it, and Dan emphatically nodded yes. He knew better than to do something like that but it was as if his body had taken over and ignored his better judgment.
