Sue was about 5'4", a natural redhead with long, curly hair and that pale, white skin. She could stand to lose maybe 15lbs, but that meant she had nice big tits - I'd guess at 36 or 38D. She was the stereotypical redhead when it came to sex, wanting lots of it, usually on her terms. She and I had dated for a while, until she cheated on me. We'd both moved on and pretty much became friends with benefits over the years - often cheating on whoever her current boyfriend was, when it seemed he didn't share some of her turn ons. I, on the other hand, knew her buttons, even some she claimed she didn't have.
One day she called me to come and show me her new car. She pulled up at my place, and we did the obligatory walk around, oohing and aahing. She wanted to show me how it drove, so we got in, and set off. She was obviously quite proud of the machine, but when we got on the freeway, I reached over and undid a few buttons on her blouse. She looked around nervously, as she was worried about being seen, but the traffic was all busy trying to get home from work rather than look to see what was going on in other cars. I undid a couple more buttons. She got more nervous. I lifted out one tit from the bra cup, and started caressing all that flesh and playing with the small, pink nipple, which quickly went hard. I pulled the other cup down, as it didn't seem fair to focus on just one tit, and she soon left the freeway and headed towards a local make-out place, still looking around to see if anybody could see her state of undress. She kept looking down to watch me playing with her tits.
When we pulled up into the parking lot we were the only ones there, and she put her tits away again, and did up the buttons on her blouse, then got out of the car. It looked like she'd come straight from work, and was wearing business-wear, so we took it slowly so she didn't twist an ankle in her heels. We went a hundred yards or so from the car park, then left the trail into the undergrowth.
