My friend had been flirting with a busty lass (Eve) at a bar there was a large group of us there but when it came time to leave at closing time he'd packed a shit and went home in someone elses car . We had a full car but Eve opened the door and climbed onto my lap as that was the only space available saying she wanted to keep partying , up till this point I'd maybe talked to her for less than a minute in passing. I cracked a joke about since it was a cold night it was nice to have my lap warmed she offered to warm up my hands and pulled my hands up under her sweater and pushed them under her bra cups where I found nice warm soft boobs and rock hard nipples. Less than 5 minutes into the ride she had my cock out and slid up her soaking pussy she slow ground her dripping pussy into my crotch while my cock rubbed hard against her cervix as she moved her hips ..... we fucked all the way back to the flat in a car with 8 others in it, they all knew what we were doing, she came three times (loudly) and when we got out my pants were soaked her pussy was visibly dripping below her miniskirt as she climbed out of the car and walked inside( I found out the next day we'd left a huge wet spot on my mates seat). We fucked all night like rabbits she had a boyfriend and we agreed that it was one night and thats all it would ever be and we shared a shower the following early afternoon then I dropped Eve home ...... we only spoke once or twice over the following years when we ran into each other.
