He fucks you hard in your tight asshole.

"If you really want to punish her for making us late, I would suggest you fuck her in the ass. You strike me as an ass man. Her rear is quite wonderful, and she can take it like the slut she is. We could stop for a moment, and you can pound her into further submission right on the side of the road here."

The driver wastes no time in pulling over. He jumps out of the front seat, taking his belt off and opening your door.

"Bend over the trunk, now."

You look to your Master, who nods and smirks at you. Fuck, if this is the BEGINNING of the night, you know you are in for it. You haven't even gotten to The Manor yet...

You step out of the car, leaving your panties on the seat. The driver pushes you down, face first on the trunk of his car. He yanks your dress up, exposing you to anyone who might drive down this side road. Pulling down his jeans he spits on your asshole. Your Master helpfully hands him a pair of cuffs that he had in his pocket. The driver cuffs your hands behind your back, and thrusts his dick into your hands.

"Feel that, you slut? Your Master here has given me permission to stretch out that cute little ass of yours with this cock. Feel how big it is? Think you can take it?" He grunts at you as you begin to massage his cock in your bound hands. It is indeed quite large, and you being to quiver in anticipation of it filling you up.

"Fuck, she's already soaking wet!" He pulls away, rubbing his dick against your wet pussy. Once he has it sufficiently lubed up, he kicks your ankles apart and jams his dick into your tight asshole. You shout in surprise, and you immediately taste your pussy. Your Master has shoved your panties into your mouth to keep you quiet.

You jump at the sudden vibrations against your clit. You remember the driver saying he wanted you to cum while he fucked you. Your Master must have brought a finger vibe for the drive, to reward you for being good. Unfortunately, you were late, so now it seems it will be part of your punishment. You feel the cab driver shove his finger up inside you, moving the small vibrator in and out of you. Your knees begin to buckle as he slams himself into you over and over again. You normally aren't very fond of taking it up the ass, but the driver isn't holding back and his cock is filling you up deliciously. The vibe is definitely helping too..

"Fuck yea you slut, take it up the ass. Take my huge cock up that ass. I can feel your pussy clamping around my finger. You love this don't you bitch, you love feeling a stranger fuck you on the side of the road."

Ashamed of yourself, you feel that familiar buildup getting stronger and stronger. You know you are going to cum soon. Moaning around your improvised gag, you feel the cock inside you starting to speed up.

"Fuck, I'm gonna cum. I'm gonna fill that ass of yours with my cum, and you are going to clean my dick off after. I want to feel you cum, bitch. I want to feel you milking every last drop of cum out of my dick with your ass!"

At this, you immediately fall apart. Your legs begin to shake with the intensity of your orgasm, and you feel your ass tighten around the dick that is furiously slamming into it. The driver pulls you back by the hips, burying himself inside of you as he releases a stream of jizz into you. As soon as you feel him pull out, you turn around and drop to your knees. He takes the panties out of your mouth, handing them to your Master. Still feeling the aftermath of your orgasm, you take his dick in your mouth. Seeing it for the first time, you are amazed that you managed to take it so well. It's one of the largest dicks you have ever seen. The tang of jizz hits your tongue, and you massage his cock with your tongue, cleaning every last drop off.

"Yea dude! She's fuckin' hot! Wanna share?" The shouts come from a car full of young men driving past you. Your Master smiles and replies.

"Normally we would, but we are late. Maybe next time, lads!"

You get back in the car, your hands still cuffed behind your back. It's going to be a long night...
