"Your ass is mine Stone? Really?" Emma Stone groaned, breaking the kiss, "Why not just tell the whole world we're having sex?"
"Awww come on, who's going to think that." Jennifer Lawrence grinned, "People see me as quirky. At best. Crazy is more accurate. So when I say something like that people just think it's me being weird, or at worst referencing some friendly competition. Which technically I am, speaking of which, in case there was any confusion, I'm totally here to collect."
Pulling away Emma crossed her arms, "I don't see why I should hold up my end of the bargain considering you endangered our careers."
"How about because you are a shameless lesbian anal slut." Jennifer pointed out with another grin.
"Well, there's that." Emma conceded, and then smirked as she turned her back to her secret lover, "But are you sure a total bottom like you has got what it takes to fuck this ass?"
To emphasise the question Emma smacked her own ass, causing Jennifer's eyes to light up and the widest grin yet to cross her face, "Why don't you bend over and find out?"
Jennifer smacked Emma's ass to emphasise her words, causing Emma to grin wickedly and begin walking towards the bedroom while clearly putting an extra bit of wiggle in her step to entice Jennifer to follow her. Not that Jennifer needed much encouragement to do so, considering this was the reason she was here.
For that ass, Jennifer practically salivating as she thought of all the wicked things she intended to do to it while staring lustfully as they made their way through the hotel suite. Actually she may have literally salivated, because Emma's ass was just that hot, clearly desperate to be abused, Jennifer struggling to control herself while the same time enjoying the thankfully short lived tease.
Once they reach the bedroom Emma crawled onto the bed and wiggled her ass at Jennifer, again making the star of The Hunger Game salivate. Jennifer then quickly crawled onto the bed behind her friend and grabbed her ass, squeezing and groping a few long seconds, partly to tease Emma, but mostly for her own enjoyment.
It was the same story when Jennifer slowly pulled down Emma's pants and panties to reveal her prize in all it's glory, making it extremely hard for the blonde not to just bury her face into the redhead's ass crack and then go to town on her most private hole. Or abuse it with a dildo. Extremely tempting, but no. There was one thing she had to do first, namely teach Emma a lesson about doubting her.
So after spending a few long seconds staring at Emma's naked ass Jennifer lifted both her hands up and brought them down in a hard double smack, the sound of flesh on flesh echoing throughout the room along with Emma's cry of mostly pain. Jennifer followed that up with half a dozen more spanks, getting a similar cry out of Emma, except these were mostly of pleasure.
Which was exactly what Jennifer wanted, at least for now. Yes, these spanks were supposed to be all about teasing her friend, until she was reduced to giving her a serious butt beating. Then things would be different. But for now this was more than that.
Because her skin was so very white Emma's butt cheeks almost immediately turned pink under the force of the blows, causing Jennifer to giggle maniacally. She promised herself that by the end of this the redhead's bottom would be even redder than her hair, but again Jennifer was determined to take her time and really enjoy this.
Mostly because Emma's incredibly hot little ass deserved that kind of treatment. But also because Emma had won every bet that they'd had until now, meaning that Jennifer had been the one bending over and getting her ass spanked and fucked, meaning that now it was payback time. And perhaps most importantly it was time to show Emma that she could be a top too.
Emma truly loved her best friend, and believed that she wouldn't intentionally hurt her, but she was beginning to regret finally letting Jennifer get her revenge. Because sure, it would be really shitty to back out of a bet when Jennifer had been fully cooperating when she lost, but Jennifer had a tendency to get carried away, and there was a real possibility that she would hurt Emma without meaning too.
Or more accurately, hurt her in a way that she wouldn't like. Or give her too much of the type she actually did. Because seriously, Emma liked a gentle spanking, but it was beginning to feel like she wouldn't sit for a week because Jennifer was just so eager to get her revenge.
While Emma definitely wasn't a pain slut or anything this wasn't the first time she'd been bent over and taken a hard butt beating. However just like those times it was the humiliation she enjoyed more than the actual pain, and she had to admit, taking a spanking from a girl she had always topped was one hell of a humiliation.
Especially as despite Jennifer's insistence to the contrary, Jennifer Lawrence was born to be a bottom. That fat ass alone should disqualify her from ever being allowed to top in any way shape or form, and now here Emma was, allowing her to indulge in this ridiculous delusion she wasn't a total bottom. What would their Black Mistress say?
For a few long seconds Emma was overwhelmed with terror, because if she thought this was bad she had no doubt that her Black Mistress would beat her butt 10 times worse if she found out about this. Then she became lost in a far more pleasant thought, exactly how her Black Mistress would prove to Jennifer she was nothing but a bottom.
It was the same thing she'd do to Emma for letting Jennifer fuck her ass, namely give her a deep, hard anal pounding. The kind which would make Emma cum so hard and frequently she would never want to top again. Or at least until she remembered how much fun it was butt fucking Jennifer. Although maybe not even then, given some stories she'd heard.
Then Jennifer picked up the pace of the spanking until she had to be giving Emma everything she had. Which was far more than Emma would have thought she was capable of, let alone willing to give her, and it almost had her begging for mercy.
But for better or for worse Emma was too busy crying out in pain to speak coherently, and Jennifer seemed far too lost in dishing out the punishment to hear it. So for a while Emma was just forced to take what she was given, which while deeply disturbing and painful was also weirdly cathartic given she had given her best friend this exact same treatment, just to see Jennifer's big booty jiggle for her.
