Bo's Human

Sadly, it wouldn't be long before that back door closed up completely, which would be counterproductive to what Bo was trying to achieve. Although, as much as she wanted to keep her tongue inside Kenzi's ass, there were equally nasty things she could do. Like spit into what was supposed to be a forbidden hole, and then more importantly, shove a couple of fingers into it.

Hell, she was even able to start with two, and then add a third and a fourth. And she was tempted to try for more. Try to get her fist into her best friend's butt. Hell, maybe this was the day she would try that? But not until after a few hours of strap-on fun. So she pulled her fingers out, something clean, and then smack that booty to emphasize her next order.

"You know what time it is now, Kenzs." Bo grinned wickedly, delivering another strike to her friend's booty, before adding, "Spread your cute little cheeks. Ooooooooooh yessssssssss, that's it. Give me that ass. Mmmmmmm, that's a good girl. Good little human bitch. Give your Mistress your butt hole, so she can fuck it for her pleasure. Ohhhhhhhhh yeahhhhhhhhh, mmmmmmm, good girl."

"Yes, Mistress Bo. Thank you, Mistress Bo." Kenzi moaned with excitement as she obeyed.

Kenzi sometimes found herself holding this position, as Mistress Bo continued admiring her prize, but thankfully, that wasn't one of these times. Oh no, instead she pressed the tip of her cock against Kenzi's butt hole pretty much right away, and slowly but surely pushed forward, stretching that forbidden hole wider them before. At least more than those fingers had. Kenzi's ass had of course, stretched like this before.

So many times in fact, Kenzi actually kinda got off on that feeling. Which no doubt wouldn't be the case for anyone else wanting to shove anything up her butt, but this wasn't just anyone. No, this was Mistress Bo. Her owner. And what could she do, except be a good human pet, and take the succubus's cock inside her most private hole?

Admittedly, Kenzi cried out in pure pain at the initial anal penetration, and pathetically whimpered before and after that. However, despite how it looked on the outside, she was still getting off on this, at least to some extent. Especially as in her current position, she was just about able to look over her shoulder, and see the happy look on the face of her Mistress.

And Kenzi would do anything to see that. And fuck, it was so hot to be pleasing her Mistress with her ass hole. Especially given that she was holding her cheeks open, providing the perfect view possible of her shit hole stretching around the head of that strap-on dildo, ready and very willing to take more.

She continued giving her Mistress that view, as inevitably, more of that dick was pushed into her rectum. Thankfully, she was given plenty of time to relax, and adjust to the stretching, although that was as much about allowing them both to savour this twisted moment, as it was an act of mercy.

Then Kenzi was mostly whimpering and crying out in discomfort, as her back passage was invaded by another woman, intent on reminding her who she belonged too. However, she also moaned in pleasure. Admittedly it was infrequent, and mostly a result of the mental high she was currently on. But it was a testament to just how submissive she had become, and just what a well-trained ass slut she was.

Before meeting her beloved Mistress Bo, Kenzi had figured that she would give up her back door one day. Hell, she got close a couple of times, but wanted to save it for someone special. And she was so glad she did, as it would be nothing short of an insult if anyone else had been inside that hole.

She hadn't realized it, even directly after they met, but that hole was made for Mistress Bo to fuck. It was hers to conquer. To claim, as the ultimate way to teach Kenzi she was inferior, and she should be doing everything she possibly could to please the superior woman. Because of that, no matter how much it hurt, it was an honour to give up her ass to her rightful owner. Especially given that ultimately, the discomfort would fade, and be replaced with pure pleasure.

Bo felt a little bad for hurting Kenzi like this, and was hoping that if she butt fucked her best friend enough, she would eventually become so loose back there, she would no longer feel pain. Plus, she got off on the idea of turning her sweet little Kenzs into that much of an anal whore. Although to be fair, even throughout this long, slow ass stuffing, it was pretty clear that the human pet was almost getting off on it as much as the succubus was. Oh yes, no one could fake those moans. In fact, Bo was something of an expert on the subject. Oh yes, her girl lifted up her cute little butt, and even pushed it backwards, silently begging for more. It was one of many, many reasons that Kenzi was the perfect fuck pet.

In fact, in moments like this, Bo wasn't ashamed of the fact that she turned her best friend into her anal loving bitch. No, she was ashamed of the fact that it took her so long to do it. Oh yes, they should have done this from the start. Yes, then Bo wouldn't have appreciated it as much, and they might not even be in this position now. Plus, she didn't want to take advantage of the younger girl, who had been roofied.

But surely there would've been a happy medium, which meant she could have enjoy this wonderful sight sooner? And this was usually one of her favourites, as there was something special about the moment her thighs came to rest against a pair of well-rounded cheeks, announcing she was all the way inside of another girl. Plus, she wasn't hurting Kenzi anymore, so that was a plus.

To help this process along, Bo even offered up some verbal encouragement, "So good, mmmmmmmm, you're so good for me, Kenzs. Look at you, taking every inch of Mistress's dick, right up your ass! Ooooooooooh yessssssssss, good little anal slut. Mistress is so proud of you. Oh yes, you make me sooooooooo happy, when you take my dick. Especially just like this. Yessssssssss, right up your slutty little human ass, no problem.

Ohhhhhhhhhhh yeahhhhhhhhh, and now you're going to take it, like a good little butt whore, huh? Oh yes, you are! Mmmmmmmmm yeahhhhhhhhhh, take it, bitch. Oh God Kenzi, I love your ass. Oooooooooooohhhhhhhhhh yeeeeeeeesssssssssss, I love fucking you! Fucking you in the ass! Making my best friend my butt bitch. Reminding her that's exactly what she is. Oh yes, fucking take it, bitch! Take it. Ah fuck!"

As she spoke, Bo leaned down, so that her tits were pressed into Kenzi's back, and she could whisper filthy things into her favourite pet's ear. Something which was clearly effective, given the way the other girl whimpered and moaned in delight. Which was usually the case when Bo began curling her hips, and thus churning the inside of Kenzi's bowels.

Admittedly, it was questionable how effective that was at helping, but it was fun, and was a further reminder of what a well-trained butt slut she was dealing with. Then, and only then, did she officially start to the sodomize her best friend. Once again getting very, very positive sounds out of her, which in turn had succubus cackling with glee.

She was pretty sure she continued the verbal encouragement throughout that, although honestly, Bo wasn't really paying attention to what she was actually saying. Oh no, she was way too preoccupied with the beautiful sight in front of her, which in this case, was watching a cock sliding in and out of another girl's ass hole. More importantly, her cock, pumping in and out of Kenzi's butt hole, as a testament to her ownership, and their mutual pleasure.

Then, to arguably make it even better, she pushed Kenzi's hands away from her cheeks, and replaced them with her own. Which of course, meant that she could squeeze and grope that little booty, and spread the cheeks whenever she wanted. Or just feel them jiggle against her thighs. Oh yes, she got whatever she wanted. As she rightfully should, as the Mistress in this relationship.

Kenzi really wanted to reached down, and start rubbing her pussy, as soon as her hands were free. Maybe even finger herself a little. Okay, it was more like a lot. Way more than that. Just like when Mistress Bo had taken her anal virginity, and a few times after that. However, the more that Kenzi got used to this, the longer it took her for her to receive permission to do that kind of thing, or better yet, for Mistress Bo to do it.

Which honestly, was a good thing. Because sure, she was aching for that extra kick which would ensure that she came nice and hard. But that would mean an end to the butt fucking, and neither the Dom or the sub was quite ready for that. Not yet.

They were both too busy savouring this precious moment, where Kenzi's most intimate place was being stretched out with a strap-on dildo. Oh yes, her precious Bo-Bo was stretching out her back door and back passage, inflicting the ultimate submission upon her. Making sure that in that moment, Kenzi's ass hole was Mistress Bo's personal fuck hole.

Hers to use however she wanted. Fuck, just the thought of that was so fucking hot, Kenzi was once again confused why upon meeting this goddess she hadn't just dropped to her knees, spread her cheeks, and begged to be put in her place. Thankfully that was now happening, and Kenzi was more determined than ever to do whatever it took to please her beloved Mistress Bo.

Which definitely involved holding back as long as her poor human body could take. Which again, was a lot longer than it used to, thanks to regularly having sex with a literal succubus doing wonders for her stamina. But sadly, she didn't have superpowers, and it wasn't long before Kenzi found herself literally 'biting the pillow'.

Not to muffle the pain or pleasure of being ass fucked, but because she was trying to avoid begging for the privilege of cumming like a little bitch with a dick in her ass. And of course, being the expert at sex that she was, Mistress Bo did a phenomenal job of keeping her as close to the edge of orgasm as possible, without letting her go over it, until the poor weak human just couldn't take it anymore.

"Please fuck me, Mistress. Fuck your unworthy slave's slutty little ass, and make me cum!" Kenzi blurted out, almost without taking a breath. Then she added as coherently as possible, "Please? Oh please give me permission to cum for you, mmmmmmmmm, like the dirty little anal bitch I am! Ooooooooooh pleassssssssssseeeeeeeeeeee, fuck my slut butt! I fucking need it!

Oh God, ohhhhhhhhhhhh yessssssssssss, fuck me! Butt fuck me, Mistress Bo-Bo. Remind me I'm nothing but your fuck hole, to use however you want. Oh yes, oooooooooooohhhhhhhhhhhh yeeeeeeeeeeeeesssssssssss, fuck me, fuck my slutty little bitch hole, and make your pet human AAAAAAAAAAAAAHHHHHHHHH FUCKKKKKKKKKKKKKKK!"

Frustratingly, Mistress Bo never actually gave her verbal permission for her human pet to cum. No, this time she simply started increasing the pace, causing Kenzi's hand to shoot to her cunt, to see what would happen. As she suspected, it was slapped away. What she wasn't expecting, was for the pace to continue increasing, leaving had no choice. It would have to do as permission, because she could no longer stop herself from cumming.

And oh God, she'd been incredibly horny going into this thing, but basically, she was cumming just from getting her butt fucked. That was like, next level anal slut shit. Ha! Which, in a very twisted way, gave her a feeling of pride. Which was the last thing she was really aware of for a while, as she was then bombarded with multiple climaxes.

Bo had always enjoyed making people cum. Even before she knew she was a succubus, there were times where it felt like her purpose in life. If it hadn't been for the urge to feed, it would've been perfect. And now she could finally control herself, and had the perfect human pet to play with, she was truly living her best life.

Oh yes, her favourite thing in the entire world had very quickly become making Kenzi cum for her, and there was something extra special, whenever it was an anally induced orgasm. After all, what better proof was there, that this girl was hers. Her bitch! Her slutty little plaything, who would do anything for her, even this. Maybe even especially this, given just how hard and frequently she could make this girl cum from this.

Of course, it was really intense when Bo grabbed hold of Kenzi's long dark hair, yanked her head back, and brought their lips together. The feeding was intoxicating for her victims outside of sex, but apparently, it was even more intense this way. And there was certainly nothing more satisfying, or yummy, for her. Especially when she was doing this exact act. Fucking another girl in the ass.

And more importantly, fucking her beloved Kenzi in the ass. Oh yes, that made it perfect. Well, it would probably be better if Bo was cumming too, but she couldn't guarantee she could control herself like that. And she couldn't risk her best friend, and the perfect fuck toy. Not until she was sure she could do it without seriously hurting her, or worse. But when it came to pushing herself over the edge, Bo had something else in mind for that.

Namely, breaking off the feeding, and growling lustfully in the ear of her pet, her own words triggering her first of many orgasms, "That's it, cum for me, Kenzi! Mmmmmmmmm yessssssssssss, cum like the little anal bitch you are! Like the perfect little human pet, who loves it up the butt. Oooooooooooh yeahhhhhhhhhh, cum for me, cum for your Mistress. Cum for your owner, you little bitch!

Ohhhhhhhhh fuck yes, I own you, Kenzi! You heard me? You're mine! All fucking mine! I should fucking take a branding iron to this cute little ass. Or at least, get it tattooed. Yeeeeeeeeesssssssssss, 'Property of Bo' would look sooooooooo gooooooooooddddddddd, on your butt, ha ha ha ha! Ooooooooooohhhhhhhhhh Goooooooooooooddddddddddddd yeeeeeeeeeeeesssssssssss, ah fuck!"

Ultimately, it was just as much as having the other end of the dildo rubbing her clit, and the sheer joy of fucking Kenzi in the ass, which made Bo cum. From there, it was a simple matter of preventing herself from feeding again, which was extremely difficult, as she practically became feral.

Oh yes, her inner succubus took over, causing her to truly brutalize Kenzi's butt, which would ensure that her sex slave wouldn't be sitting down, or even walking, for at least a few hours. Hell, Kenzi was finding it increasingly hard to do that for days following. Which Bo found perversely amusing. But mostly, it was fucking hot. Like public proof that Kenzi and her cute little ass belonged to her. The thought of which, of course, made her cum harder.

Suddenly, she became aware of Kenzi frantically tapping out, which thankfully allowed Bo to get a hold of herself long enough to slow things down, and come to a complete stop. Although, there may have been one last long, slow thrust, which made sure that when they came to a stop, every single inch of her dick was inside Kenzi's ass.

Which wasn't a kind thing to do, but the animal within Bo really enjoyed spooning a lover like that. Especially her beloved Kenzi. So exactly what she did, rolling them into their sides, and gently holding the other girl until she stopped shaking from the aftershocks of her orgasms. Then, as they came down from their highs, Bo gently stroked Kenzi's hair, and whispered words of encouragement to her.

"That's a good girl, mmmmmmmm, that's a very good girl. Oh Kenzs, you were so good for me. Such a good little human. Mmmmmmmm yeahhhhhhhhhh, the perfect anal loving human pet." Bo purred over and over again into Kenzi's ear, before finally playfully pushing, "Who's a perfect anal loving human bitch? You are, oooooooooh yessssssssss, you are. Ohhhhhhhhh, what are you?"

"Your human, Mistress Bo." Kenzi replied softly, then deliberately whimpering, "I'm yours. All yours. Your perfect anal loving human pet. Fucking brand my butt, and then make me pull down my pants whenever you want, so you can show me off. Show everyone that you own me. That I'm yours, mmmmmmmmm, your perfect anal loving human pet."
