Offer him a choice - 5 dollars or 5 minutes with Carrie.

You check your surroundings. The neighborhood is quiet. All of the nosy neighbors are asleep. Completely unconcerned with being seen, Carrie stands next to Adam's car awaiting your answer.

"Alright, I'll offer him a choice. We'll see if you're still serious about 'anything'..."

Carrie beams at you, hardly able to contain her excitement. You tap on the passenger side window. Adam rolls it down, looking at you curiously. Carrie crosses her arms and shivers a bit. It's gotten fairly cold outside. Little goosebumps cover her naked body.

"Okay, Adam. For your tip, you've got a choice."

You lift your phone and show him the app, "Either I can tip you five dollars."

You lower the phone and gesture towards Carrie, "Or you can have five minutes with my girlfriend."

He stares at you blankly for a moment before scrunching his face up and scoffing loudly.

Carrie chimes in, "If you choose the five bucks, I swear I'll make him rate you 1 star."

Doesn't sound like the words of someone that wasn't going to go through with it...

Adam says, "Very funny joke, guys. This is definitely the most interesting ride I've ever given but I need to get going."

As he starts to pull away, Carrie lunges forward and grabs the door. Adam taps the breaks and stops.

Thrusting her chest in the window, Carrie says, "Don't believe him? Here. Touch them."

You're not sure how you feel about Carrie doing this without your permission but decide to see what happens.

From inside the car, Adam says, "Is this some kind of prostitution sting or something? Are you filming me right now?"

You take another look around the neighborhood before saying, "Nobody's filming and nobody is watching. It's just the three of us."

"You guys are actually crazy."

Carrie pouts, "Come on... one finger. Give one of my boobies a little poke."

Adam pauses for a second before cautiously reaching a shaking hand across the passenger seat.

Carrie chuckles, "I'm not going to bite you. Unless that's what you want me to do in your five minutes."

The driver's finger moves closer. Slowly, it touches and presses into the underside of one of your girlfriend's breasts. Suddenly, he jerks his hand away.

"See, that wasn't so bad. Now why don't you give them a proper feel?"

There's another long pause. Adam looks around as if to confirm that he isn't being swarmed by police or a film crew. You can't help but smirk to yourself as you imagine a show where perverted Uber drivers are caught in the act.

Slowly, he reaches forward again. This time he cups Carrie's left breast. His hand is shaking as he massages it gently, feeling the weight in his hand.

Carrie turns her head and grins at you mischievously, "Adam, don't forget the nipple."

His fingers slowly work their way to Carrie's dark little brown nipple. It's very hard. Probably a combination of the situation and the cold. For a few seconds, Adam grazes his fingers across your girlfriends hard nipple and even pinches it a little bit.

Carrie steps back and Adam can no longer reach her chest.

She smirks at him, "Believe us now?"

The driver looks over at you, "You're actually serious? What... what exactly do you mean by five minutes with her?"

"Well, I'll invite you inside and you'll get to play boyfriend to Carrie's girlfriend for five minutes. I'll do you a favor and not count just now as part of your five minutes. Consider it a teaser. Knowing my girlfriend, she'll do whatever you ask."

"I can't believe this... I just..."

"You're looking at her naked right now and you just touched her breast. Is it really hard to believe that she's okay with a little more?"

Adam switches his focus between you and your girlfriend several times. Is he actually having trouble deciding? This should be an easy choice. What's the hold up?

"Come on, Adam. I think that Carrie is getting cold. Make up your mind."

He looks at you and asks with genuine concern on his face, "What about you? Why are you okay with this?"

You shrug, "You seem like a nice enough guy. Carrie and I have a pretty adventurous sex life. Call it morbid curiosity if you want but I want to see what happens next. Plus, I'll get to save five dollars."

There's another long pause before he speaks, "I... I guess I'll take five minutes with Carrie..."

Your stomach lurches. It's suddenly so real. Was this really going to happen? Are you actually okay with this? You feel strange... You're about to let this 20 year old kid do whatever he wants to Carrie? You can always back out, right? Carrie seems so excited though, she's practically hopping up and down in place. Maybe in order to use this 'Anything' promise to it's fullest, you're going to have to do some soul searching to see what you're okay with. If Carrie is willing to do this, the opportunities that the 'Anything' promise presents could be far more wide ranging than you initially assumed.

You hope your own nervousness isn't obvious when you say, "Awesome. Come on inside."

Carrie squeals in delight and practically runs to the front door. You linger by the car and wait for Adam. He gets out, body language showing that he's extremely nervous, and locks his car. The two of you walk to the door. You unlock it and Carrie instantly bolts inside.

You hold out your arm and say to Adam, "After you."

He gives you one more bewildered look and enters.
