Tracy

The decision seems to fall on you as to who will be sitting where in the cab, but you have a sneaky idea sprouting in your head.

"Well Mia, are you coming with us or not?"

Mia looks slightly upset that you've chosen Tracy over her to sit next to you but accepts your decision and enters the cab. Then Tracy enters and she smiles at you as she does so, clearly pleased that you've chosen her, but she doesn't realise what you have in mind. Finally, you enter the cab and sit next to Tracy, who starts playfully rubbing your cock through your pants whilst Mia looks on with jealousy. You tell your driver your address and he starts the drive home, now your plan can start to come to fruition. As soon as you pull off from the curb you give Tracy a gentle nudge with your elbow, indicating for her to partake in the same act as she did on the drive to the bar. She turns to you with a confused expression, but then the realisation dawns on her as she realises what you expect of her. Her eyes plead with you, begging you to take back your silent command but you just look back with a merciless expression on your face. She resigns to her fate and looks over at Mia before looking forward to the driver.

"Excuse me sir, would you like a blowjob?"

Mia looks at Tracy with a frown on her face, clearly shocked at the words that have just come out of her sister's mouth.

The driver on the other hand seems to think this was a joke and laughs before answering "you have no idea love."

Tracy turns to you as if to ask 'what now?' but you simply shrug and point forward, indicating for her to proceed. She takes a moment to compose herself before going through with it, clearly rattled by the fact that her twin sister is sitting next to her, judging her for the depraved acts she's committing. Having built up the determination to do it, she shifts forward so she's bent over the arm rest between the two front seats and works her way towards the driver's cock.

He's taken aback by her actions and exclaims "whoa there, what're you doing?"

"Giving you a blowjob sir, like you asked."

"Yeah but I didn't think you were being serious."

"Well I was, so would you still like one?"

The driver pauses for a moment as he thinks over the prospect of receiving head from the absolute bombshell leaning forward to him. Eventually he comes to a decision and without making a sound gives a nervous nod. Tracy proceeds with her task and fishes his cock out of his pants, before licking it up and down. Once she's had her fun toying with the driver, she starts sucking his dick, bobbing her head up and down on his cock and moaning as she does so. He isn't particularly large and so she has absolutely no trouble taking the whole thing down her throat.

With Tracy busy you turn your attention to her sister, who's now cheekily smiling at you as she realises that she has you all to herself now. She shifts over slightly in the seat so the two of you are closer together and you start passionately making out. You're rubbing your hands all over her body, playing with her amazing tits and squeezing her ass. She's letting out soft moans as you do so, letting you know how turned on she is. Her hand starts reaching towards your crotch, blindly searching for your cock. Eventually she manages to get it out and starts playing with your dick until you're fully erect. Once she does so, she detaches her lips from yours and starts moving down south to give you the same treatment her sister is giving the driver. Once she's bobbing up and down on your cock, slowly working her way towards deepthroating your entire length, you reach over towards her ass and hike up her skirt. Her pussy is completely exposed, since you have her panties in your pocket. You start playing with it with your hands, rubbing around her moist labia and working your way towards her clit. As you do so, she starts moaning around your cock, filling the cab with the whorish sounds of the twin sisters.

"Tell me whore, are you gonna be a good girl like your sister and do as I tell you?" Her pussy twitches at the sound of you referring to her as 'whore'.

Mia lets out an eager "Mmmhmmmm" around your cock, perhaps not aware of exactly what you have planned for her but content in her aroused state.

"Good answer. From now on you'll address me as sir, understand?"

Mia lifts herself slightly up on your cock so her lips are just wrapped around the tip and answers "yesh shir."

It seems Tracy and Mia are just as obedient as each other, and have the same insatiable hunger for cock too. You decide to test just how alike they are by grabbing Mia by the hair with your other hand and forcing her down on your cock. She's surprised by your actions and puts her hands on your thighs to try and resist out of instinct.

"MmmmMmmMmmm." She lets out a muffled scream around your cock, but after a few seconds of struggling you pull her by the hair off of you. A thick strand of saliva connects her mouth to your cock and she starts breathing heavily as you hold her face up to look at her.

"Good whores don't struggle to deepthroat a cock."

"Sorry sir."

"Let's try that again and this time keep your hands behind your back."

Mia nods before you push her throat back down on your cock. She still lets out some muffled sounds of struggle and reactively shakes her body a bit, but this time she keeps her hands behind her back. Once you can feel her stop resisting, you start lifting her head up and down on your cock, essentially using her throat like a fleshlight. She slowly starts to relax her body completely and accepts her new role as a human fleshlight, only making gagging sounds as you **** her head up and down on your cock.

Whilst you do this, you use your other hand to lift Tracy's skirt, exposing her bare pussy. Her hole is dripping wet as you start playing with it with your fingers, enhancing her moaning around the driver's cock. As you continue toying with both sisters you develop an idea for what to do next.
