I pull my tee shirt up over my tits so my bra is visible and my tits can feel the wind rushing in through the window.
I pull my right tit out of my bra so it's sitting on top of the bra cup with the seatbelt rubbing against it. The rubbing makes my nipple pucker up and get hard. I drive like this for awhile until I can't stand it and have to roll the hard nipple between my thumb and forefinger. It gets even harder and the areola goes from half dollar size to nickel size. I then reach into a cooler that I brought with me for cold drinks and take out an ice cube.
I suck on the ice cube making it melt a little and then slowly pull the seatbelt away from my tit and rub the ice cube on it. The ice cube melts quickly and my whole tit is rock hard from the ice and the wind blowing on it. MMMMMMM, it feels so good!
Then, I pull my left tit out of my bra so it's sitting on top of the bra cup and let the seatbelt rub it for awhile. I drive like this for awhile longer and squeeze my nipple, pulling hard on it, getting it ready for the ice cube that is going to cool it down. Then I reach in the cooler and pull out another ice cube. This one I rub over my lips to cool them down a little before sucking on it so it will melt. Then I hold the ice cube in the air between my tits, causing the melting cube to drip down in the valley between my ample breasts. OHHHHHHHH! Now I rub the ice cube over my nipple, causing it to get very hard and the areola to shrink and pucker up.
By this time, I am very hot and my pussy is dripping. I can feel the moisture between my thighs soaking my panties. I reach down and rub my hardening clit over my jeans. I move my hips in little circles, trying to get the seam of my jeans lined up with my clit. After I get the seam positioned in just the right spot, I am wiggling my hips so the seam rubs against my clit hard. This action causes me to cum HARD!
