Absolutely

Mia looks towards her sister and then back into your eyes, before biting her lip and nodding. You grab her by the arm and lead her out of the bathroom and then out of the bar altogether. Once you're out of the bar you turn and walk along the footpath until you come across an alleyway which you lead Mia down. Not far into the alley, there's a dumpster which you decide will provide enough cover from the street for the two of you to fuck. You drag Mia behind it and pin her up against the wall, passionately kissing her. She starts softly moaning as the two of you make out and you rub your hands all over her body. Whilst making out, you use one of your hands to pull one of her tits out of her dress, which is easy thanks to her lack of a bra, and start fondling it, running your thumb over her nipple which causes it to harden out of arousal. Deciding that's enough breast play, you work your hand further south and lift up her skirt a little to find she is in fact wearing panties. Perhaps she wasn't quite as much of a whore as her sister. You reach down beneath her panties and start rubbing her pussy, which is already moist with her juices.

After you've had enough of toying with this slut, you turn her round so she's facing the wall and bend her over slightly. She plants her hands on the wall for stability due to your rough treatment. From behind, you now fully lift up her dress so her ass is fully exposed. She's wearing a skimpy G-string that sinks in between her ass crack, making the thin string completely unnoticeable from behind. You pull her slutty panties to the side to expose her pussy and ass. Another difference you can notice between Tracy and Mia is the shape of their ass. Due to Tracy's extensive anal fuckings over the past couple weeks, her ass had changed so her cheeks were more parted and her hole was more visible. Seeing Mia's ass reminds you of how Tracy's used to look before you had started fucking her in the ass.

With Mia's pussy now exposed, you pull your cock out and stick it in her pussy, slowly pumping in and out. You work up the pace until you're roughly clapping her cheeks, which would likely be audible to anyone passing by on the street. Mia's moaning like a whore now, just like her sister. You grab her by the hair as leverage to continue pounding her as hard as you can, which she seems to love based on the increased volume of her moaning.

"Oh fuck, keep slamming my pussy just like that. It feels so fucking good."

"So what did you think of your sister in there, quite the slut wasn't she."

Mia laughs between breaths as you continue pumping in and out of her pussy. "I thought I was bad, but she's a filthy fucking whore. I can't believe I thought she was the well behaved one, getting into a stable relationship and everything. Meanwhile, she's having a bar full of strangers run a train on her in a toilet stall."

You can feel Mia getting wetter at the thought of her own sister being fucked by a group of strangers in a bar just a few metres away. Her moans got louder and louder as she started to approach the brink of orgasm. She didn't seem to care who might hear her, all she could think about was how hot this was right now. Mia seemed to have the same tell-tale signs of when she was about to cum as Tracy and so you picked up the pace to help finish her off.

"Oh fuck! Oh fuck! Oh fuuuuck!"

It turned out squirting was genetic, because as Mia came, her pussy started gushing all over the ground of the alleyway. Mia went silent in post-orgasmic bliss as you continued pounding her pussy, feeling your own climax drawing close. You decide to use the hand not holding her roughly by the hair to pull the rest of her dress down, so now both of her enhanced tits are out swaying in the night air. You grab a hold of one and start playing with her larger silicon breast as you feel yourself on the verge of orgasm, perhaps you'd have to get Tracy a pair of these. Her tits were already decently sized, but some larger ones couldn't hurt. At the thought of this you feel your climax coming on and pull out of Mia's pussy, spraying your cum onto her ass cheek. The two of you stand there for a moment, breathing heavily after your intense fucking. You put your cock back into your pants and prepare to leave. But before you do, you grab Mia's panties and rip them off her, easily snapping them since they're just made of thin strings.

"Hey, what the fuck!"

"A slut like you doesn't need panties. Besides, I want something to remember you by."

Mia sighs in response and starts to compose herself. You look towards the entry way of the alley to check if you have any onlookers, which it doesn't seem you do. When you look back to Mia, she's using her fingers to lick up your cum from her ass. She sees you looking at her with a slightly surprised look on your face and tries to justify her actions.

"What, I wasn't gonna just leave it there to soak into my dress."

"You and your sister have a lot in common."

Mia frowns, but then moves past your remark and finishes cleaning herself up, also pulling her dress back into position. Her hair is a mess due to you pulling on it as you fucked her but she does her best to compose herself. With Mia all sorted, the two of you head back to the bar.
