Two weeks ago my boyfriend and I went to the beach, and it was about an hour drive. Well, he surprised me during the car ride by showing me that he had bought me a vibrator. It was really small, probably half the size of an Easter egg.
At first I rejected his pleas to watch me use it while we were on the highway, but my curiosity led to horniness and so I gave it a shot and it was WONDERFUL! He kept telling me something like: 'don't cum until I tell you'. I didn't understand why, but I figured I would play along.
His car has tinted windows, but it still felt really erotic and slutty (in a good way) to pleasure myself with cars and trucks all around us. Truthfully, I don't think anyone could see, or really tried to look. But it was still very hot.
I had never done anything 'exhibitionist' like that, so it was totally new to me, and very hot. I have been really horny before, and I've even felt the 'good slutty' feeling, but only a few times, like when I would talk really dirty with him during sex, etc.
I still remember the feeling of the warm sunlight on my pussy through the windshield while I masturbated: with my feet in the air and my knees near my shoulders it looked like my labia popped out two inches from my vulva.
I definitely could have orgasmed about 10 times during that trip, and the longer I went without, the more horny I got. I have never had sex or masturbated for more than probably 20 minutes before, but this was almost an entire 60 minute drive. I was absolutely CRAZY with arousal. He was stroking himself over his shorts, but he wouldn't let me touch him; strangely, I found this very hot.
By the time we got off the highway my wetness was everywhere: all over the vibrator, and my fingers, my mouth, and all over my skin around my pussy. I felt so horny and depraved and surprisingly, I loved it.
I asked him what was next and he said he would tell me 'in a moment'. I didn't know what he had in mind but I was so horny I was ready for anything.
To make a long story short(ish), he told me to wear my bandana on my hair like I do to keep my hair up, and wear my sunglasses, then he rolled the windows down and occasionally had me lick and suck my nipples when we were next to other cars, and twice with people on the sidewalk very close to us.
I have never been so absolutely wet and horny in my life as that day.
We had a bunch more fun the rest of the afternoon, but this story is too long already.
