Get fucked.

James had first had a cock inside of him when he was fifteen, and since then he'd grown a bit of a reputation for it, but he'd never taken a cock as big as the one he was now presented with.
Licking his lips in anticipation of the challenge ahead of him, James quickly tells the other man to get out of the car (the traffic is at a standstill after all) and to come round to the drivers side.
James unbuckled his seatbelt as well, and stepped out of the car as the other man got to his door.
"Sit down, and move the seat back" he commanded, and the other man did just that.
Meanwhile, James unbuckled the belt on his jeans, and slid both his jeans and his underwear down to his ankles. There were some people watching from neighbouring cars, and one woman who looked suspiciously like she was trying to subtly finger herself whilst watching, but no one seemed to think it was out of the ordinary.
With his ass exposed, James wished that he wouldn't need any prep, and slid a finger down to his hole to check on the changes. His hole was definitely looser, and he could easily fit three fingers inside himself if he had wanted to. He could also feel the unmistakable slippery wetness of lube inside his asshole, so he decided that his wish must have worked.
He pressed the button on his car keys to put the convertible roof down, giving himself some more headroom, and then he slid into the car, positioning himself above the other, waiting, man.
He began to lower himself on the monster cock of the man behind him, feeling his passage open around it, filling him to an extent he'd never experienced before.
