My gf and i were driving back from the holidays several hours from home. We kept our hands on each other's thighs until she decided to slide up a bit more and rub my cock through my pants. I got hard almost instantly and decided i wanted her tits out, so i pulled her top down exposing her tits to any drivers close enough to us. After playing with her nipples a bit she unzips my pants and pulls out my, now rock hard, cock and jerks me off. I reach down under the short skirt she decided to wear and rub her already wet pussy, occasionally licking my fingers to taste her. After about 10 minutes of rubbing her pussy, she puts her legs on the dash, now exposing her wet pussy and rubs herself while i do the same. We both keep going until she cums. Right as I'm about to finish, she takes my tip in her mouth and swallowed the whole load.
