You do

Unfortunately for you, he had the advantage of teasing you for several minutes before you started this little competition of yours. And his tongue is simply that good. You can't think straight anymore and can't focus on sucking him anymore, you just keep his cock in your mouth, your head barely moving, the only friction coming from the few times when he moves on his own. Your moans of pleasure are slightly muffled by his dick in your mouth as you feel yourself getting closer and closer to the edge.

You lose the battle when he suddenly sucks on your clit, teasing it with fast licks while your nub of pleasure is trapped between his lips. The intense feeling is enough to push you over the edge and you cum hard, your legs tensing and closing over his head, screaming your release over his hard cock as you see stars. His tongue gradually slows down, easing you off the peak, your legs gradually opening again and resting on the backrest of the seats, taking huge gulps of air around his rod still in your mouth.

His task accomplished, you feel him trying to exit your mouth. But you're not done with him yet and close your lips around his cock, trying to suck it back in your mouth. You hear him chuckle at your tenacity. "Well Miss, if that is what you want. I will give you a taste of what awaits you if you were to lose a game in the city." He plunges back into your waiting mouth, and starts moving in and out, essentially fucking your mouth. You feel a finger slowly tracing your drenched lower lips, spreading your juices all over them as he keeps teasing you while using your mouth. You don't resist it, just keeping your mouth open as he pistons in and out of it, faster and faster. Grunts of pleasure escape him as he puts a hand over your throat, holding your head in place as he increases the pace, his finger moving faster over your slit and bringing you close to another orgasm.

As you're about to experience another mind-blowing orgasm, you feel him tensing. "Get..ready Miss...I'm about to.....cum". He pistons a few more times in your mouth before going still and groaning in pleasure as he cums in your mouth, filling it with his salty sperm. Incidentally, it also caused his fingers to curl a bit, driving two of them in your dripping pussy and pressing over your clit with his hand, which is enough to make you cum again, your vagina clamping around his fingers as you moan loudly.

After gathering your spirits, you swallow his load and shakily move to lie down on the couch, your breath coming in pants. From the corner of your eyes, you spot the driver taking a couple of towels from the overhead compartment of the carriage and lovingly towel your face and your crotch dry. Once done, he cleans and tucks himself as you catch your breath.

That was without a doubt the most intense sexual encounter you've had recently. You don't really know what came over you, you've never been this.....kinky before but for a reason that escapes you, you felt like doing it. Is there something in the air here that makes people behave differently? Or was this side of you already present all along, just waiting for the right time to make itself known? Something to ask some people here later maybe.
