One nearby in the city

You had chosen a nearby bar that was popular with people your age and younger, sometimes frequented by some kids from the local college. Seeing as you would both likely be drinking, you opted to order a taxi to take you there, which had just arrived outside your house. Being a caring boyfriend and quite the gentleman, you open the door to the cab and let Tracy in first before jumping in yourself.

"Where to sir?"

"Princetown bar on Nancy street thanks."

The cab driver nods and starts driving towards your destination. After about five minutes, you nudge Tracy and point to the driver, reminding her of something you had previously talked about. Taking the hint, she turns to the driver to ask him a question.

"Excuse me sir, I was wondering if you'd like a blowjob."

The driver looks at her in the rear view mirror with a confused look on his face, smiling as if he thinks it was some kind of joke.

He chuckles and says "I'm not quite sure I understand you ma'am."

Tracy continues looking at him, before asking again. "Would you like a blow job. Some road head. I can suck your cock while we drive, if you'd like."

Now the driver looks at you in the rear view mirror with a confused expression. You look back at him and reassure him.

"My girlfriend is a slut who enjoys giving pleasure to men any way she can. I'd recommend saying yes, she gives amazing head."

The driver pauses for a moment, thinking over this strange offer. Finally he reaches a decision and answers.

"Alright then, sure, God knows I'm not getting any head otherwise."

Tracy smiles and unbuckles her seatbelt before leaning her whole body forward and inserting herself in the gap between the two front seats. In this position she's fully leaning over so she can reach around and get at the driver's dick. Meanwhile, she's fully exposing her ass and pussy to you in the back seat due to her compromising position. You can see that she's now dripping wet, leaking her cunt juices down her inner thigh. You decide to give her a bit of pleasure yourself and start playing with her pussy.

In the mean time, Tracy has unbuckled the driver's trousers and started sucking him off which you can hear from the back. You can also see her quickly bobbing up and down on his cock as she skips any foreplay due to the short length of your trip.

The driver doesn't last long thanks to your girlfriend's expert cock sucking skills, and blows his load into her mouth, letting out some groans of relief as he climaxes. Tracy kindly cleans him up before doing his trousers back up and shifting back into her position in the back seat. You look over at her as she licks up a drop of cum that spilt out onto her bottom lip before doing her seat belt back up again.

It isn't long before you reach your destination and the cab driver lets you out, taking a small amount off your payment thanks to your girlfriend's hard work.
