My Wife Is Pissed

We were driving back from an family gathering were my wife had a little too much wine with her sisters. As usual I didn't have any alcohol because I had a two hour drive home. When we left her sister's house around mid night my wife was more than a little tipsy. As we were driving down the empty two lane country highway I started to reach over and play with her. She was enjoying me rubbing on her clit. She leaned the seat back, pulled her pants and panties around her ankles, unbuttoned her shirt and removed her bra. I kept rubbing her and squeezing her tits until eventually the wine took over and she fell aspleep.
After a while I stopped feeling on her and just focused on driving. A while later I had to pull into a gas station, it wasn't open and no one else was there so I didn't bother waking her. I was out pumping gas and another car pulled in. I was thinking, surely they'll go to a far pump. I was wrong, they start pulling right in front of us. Naturally I open the door and say, "babe, cover yourself." Being out of it, she sits straight up and says huh. Worst timing ever! Two guys in the car are looking right at her tits. I said, LAY BACK DOWN! It's at this point she looks forward and sees the two guys in the car staring directly at her. She screamed and quickly fell back in the seat. I hung the pump up and got in the car and we left. She bitched at me the rest of the way home, saying shit like I allowed her to be violated and what if there were cameras at the gas station and she ends up online. Sounds outlandish but my wife is a shy, conservative little woman. I really felt bad because she was so embarrassed, but honestly think she was being a little too dramatic about it all. One thing is for sure, I don't think I'll get her naked in the car again anytime soon.
