Spencer Hastings paced back and forth in her kitchen, stopping every so often to sip her 11th cup of coffee today. She was always heavily caffeinated and stressed out about something, but for once, this wasn't about schoolwork. This was about Alison's plan to seduce her Mom and help Spencer turn her into her bitch. Spencer just couldn't stop thinking about all the ways it would go wrong, and just how wrong it was on so many levels.

She had never really got along with her mother, had always felt like the redheaded step child, or at least second best next to her older sister Melissa, but just because she hadn't been good to her didn't mean that her Mom deserved this. And yet, even though she thought of calling it off like a million times, Spencer never made it as far as reaching for her phone, because the terrible truth was she wanted this.

Prim and proper Spencer Hastings wanted to make her own Mom her fuck toy, and in about an hour she would do everything possible to make her most forbidden fantasy come true. In the meantime she was very much looking forward to meeting Alison's bitch, and perhaps more importantly fucking her, Spencer's entire body tingling with anticipation as she knew soon she would be topping her first ever girl.

And not just topping her, but fucking her up the ass. Oh yes, Alison promised her that she could bang her bitch in the butt, and Spencer couldn't wait for that fantasy to come true either, and she wouldn't have too as she finally heard her doorbell ring.

She was a little surprised that Alison didn't use the back door, as it would have been appropriate and shield them from prying eyes, but this way there would be more of a reveal. When she reached the door Spencer glanced at the clock. Ali was nice and punctual, which would mean they had plenty of time to 'set up' and for Spencer to enjoy Alison's bitch.

Who, despite her best efforts, she still had no idea who it could be. Well, she had a few guesses, but when she opened the door she found she was way off. In fact, Spencer could have never guessed who exactly would be standing next to Alison and looking adorably awkward.

"MONA!" Spencer exclaimed, lowering her voice as she added in disbelief, "Mona's your bitch?"

"Not just my bitch, my anal loving bitch." Alison said proudly, before turning to her pet, "Isn't that right sweetie?"

Mona blushed, nodded and then when she saw Alison giving her a look out of the corner of her eye mumbled without looking up, "Ye, yes."

There was a moment of silence were Spencer continued staring in disbelief, and then Alison said, "I know what you're thinking, and yes, I could do better, which is why I'm not telling everyone I'm butt banging loser Mona, but you'll understand when you get a good look at her ass. Seriously, Mona... turn around and give Spencer a good look at that perfect ass I love fucking so much."

Briefly Mona looked up at Ali, obviously silently begging her not to make her do this. Or at least not in public. But all Alison had to do was give her a stern look and Mona lowered her head and turned around so she was facing the street, giving Spencer a good look at her skirt covered rump. Spencer briefly looked at it, then glanced around to make sure no one was watching before taking a longer, better look.

Luckily for them all, or at least Mona and herself if Ali was feeling shameless, it was winter so it was already dark and the street was deserted. So Spencer was free to stare even as Alison lifted Mona's skirt to reveal an admittedly fuck-able looking ass, Alison giving her a few long seconds to stare at it before talking again.

"See what I mean?" Alison asked as Mona held her skirt in place, allowing the blonde to use one hand to grope her bitch's butt, "I wouldn't have thought loser Mona could have an ass this fuck-able either, but just look at it. Just look at this hot little ass. I swear it's the Goldilocks of asses. Not too big, not too small, but just right. And her hole, mmmmm, mmmmm, mmmmm, trust me, normally it's tight as a drum. Sadly as we're pressed for time you're going to have too find that out later, but trust me, it's almost just as fun when she hadn't been stretched out first, and doesn't her ass looks so cute with a butt-plug stretching it?"

"Yes. Very." Spencer stammered in agreement as Alison and used both hands to spread Mona's butt cheeks, giving the best look possible at that sex toy stretching the other brunette's most forbidden hole.

"Wanna touch it?" Alison grinned, letting go of Mona's cheeks, "Go ahead, have a squeeze of Mona's bitch ass. Feel how surprisingly flawless the skin is. I don't mind, and neither does Mona. Do you Mona?"

"Yes Alison." Mona agreed softly, feeling pathetic as she quickly clarified, "I mean no, I, I mean I, I... I don't mind."

Ignoring the sub Spencer licked her lips and said, "Maybe I will, once you're both inside."

Spencer then stepped back to give them some room, and although she and Alison had a bit of history of being in competition with each other Alison shrugged and gave this one to her, "Fine, spoilsport. Come on Mona."

Mona quickly pulled down her skirt, turned around and followed Alison into Spencer's house, grateful that no one had seen what had just happened to her. God, what HAD happened to her? Less than a month ago she was a proud top, now she was allowing herself to be humiliated and pimped out to Alison's friends, even now timidly walking behind the blackmailing bitch who had taken her anal cherry as they approached the place of her next butt fucking.

And Mona tried to tell herself she was still only doing this because of the blackmail, but the truth was she was beginning to enjoy being Alison's bitch. If she was really honest with herself she had enjoyed it from the start, and was eagerly anticipating what was going to happen next, and the way Ali and even Spencer continued humiliating her.

Once they reached the kitchen Spencer turned to Mona and said, "Wow, I still can't believe it."

"Oh come on, you've seen the way she looks at Hanna. You had to know she was a dyke." Alison grinned.

"Yeah, but since her makeover I always figured she was a top." Spencer said.

Alison giggled, "Oh, she wanted to believe she was, but she was never anything but a pretender. A wannabe. A bottom masquerading as a top. Yes, A was just a bottom the whole time. Here, I'll prove it to you. Mona, strip."

Despite everything that had already happened to her Mona blushed at this command. Of course she didn't hesitate, doing her best to make it nice and slow so the other girls would enjoy it, finding herself constantly glancing at them for their approval. Spencer was happy to give it, obviously staring at her the entire time.

Alison was less generous, actually pulling off a half convincing, bored expression as she examined her nails, although Mona caught a lustful look from her more than once. Those looks made her blush even more, mostly because of the effect they had on her, Mona desperately trying to ignore that in favour of just doing as she was told.

"So?" Alison questioned with a smirk.

"Wow..." Spencer mumbled, before unconvincingly adding, "I mean, I'm not gay, but she is gorgeous."

"Sure you're not." Alison said, unable to keep the sarcasm out of her voice, before seriously adding, "So, do you wanna start with a pussy licking, or-"

"No, we're here to practice my butt fucking skills, before..." Spencer blushed as she trailed off, before admitting, "Besides, I... I just really want a piece of that ass."

"I don't blame you." Alison chuckled, "Well, go on then. Go get your strap-on, while I prepare my bitch for you."

"Thanks Ali, you're the best." Spencer said as she began rushing upstairs.

"I really am." Alison happily agreed, before turning to Mona and ordering her, "Bend over bitch! Let's see that pretty little whore butt I own."

There was a brief battle of wills between them, then Alison's playful smirk faded to a warning look, causing Mona to whimper and bend over the nearest surface, which just happened to be the kitchen table. Instantly Alison's smirk was back, unsurprisingly as she went back to groping Mona's ass for a few long minutes, smacking it a few times for good measure.

Then the sound of Spencer coming back echoed throughout the empty house, and soon the tall brunette appeared wearing a strap-on dildo, her bra, and nothing else. Spencer then wordlessly walked around to get a good look at her prize, before gasping with delight and then licking her lips.

"Wow Ali, you really are the best." Spencer grinned wickedly.

"Was there any doubt?" Alison chuckled, "Here, let me prepare her for you."

With that Alison pulled Mona's ass cheeks apart, grabbed the butt-plug and started twisting it around inside of Mona's bowels, causing poor Mona to cry out in humiliating pleasure. It only got worse when Alison began pulling the butt-plug out of Mona's ass only to push it straight back in.

Hell, more than a few times she only pulled it back as far as Mona's back hole was stretching around the widest part of the plug, before pushing it back in. Which Mona knew from experience would prepare her for what was to come, but it didn't make it any less humiliating. Which was exactly how she felt about watching Spencer rubbing lube into her dick, especially as both Spencer and Alison were grinning the entire time as they did this.

After enjoying the show for several long minutes Spencer asked hopefully, "My turn?"

"Sure." Alison grinned wickedly.

Spencer then gasped in delight as Ali slowly pulled out Mona's butt-plug one final time, the taller brunette bizarrely finding the shorter brunette's butt hole breath-takingly sexy as it slowly stretched to allow the plug to leave and then stayed stretched open when the plug was removed.

To give them both a better view Alison used both hands to spread both of Mona's ass cheeks as wide apart as she could, and after staring lustfully at the gaped ass hole she looked up to see the desire filled look on Spencer's face and then giggled wickedly. God, Spencer had waited for this moment her whole life, and now she was going to finally butt fuck another girl. Oh fuck, this was heaven.

"Go-ahead Spencer." Alison encouraged, "Fuck my bitch's butt!"

Not needing to be told twice Spencer grabbed a firm hold of her dildo, pressed the tip against Mona's stretched shit hole and pushed forwards forcefully, almost literally drooling as that loosened hole easily took the head of her strap-on inside it. Spencer's strap-on was wider than the butt-plug so there was a little stretching, but not much, Spencer finding it just as easy to slip the first few inches in before finally finding resistance.

Even then it didn't take a lot of effort to slide the rest of her cock into Mona's ass, Spencer savouring the moment for a few brief seconds before officially beginning to butt fuck another girl for the first time in her life.

She slowly pulled back with her hips, and then just as slowly pushed forwards, repeating the process over and over again as Ali continued spreading Mona's butt cheeks, giving them both a perfect view of this bitch's butt hole stretching around Spencer's cock as she pumped it in and out of the most private hole of the girl who had previously tormented her under the name A.

Oh yes, Spencer was finally getting revenge for all those months of torment, and doing it in the best way possible, inflicting unspeakable levels of humiliation upon the other girl, while enjoying herself an obscene amount. And she wasn't the only one, as Alison delighted in pointing out.

"That's it bitch, moan. Moan like an anal whore while my friend fucks your ass!" Alison taunted her bitch, "Moan like the anal whore you are as my friend fucks you up the ass! Oh yeah, fuck Mona's dyke ass Spencer! Mmmmm, mmmmm, mmmmm, pound that lesbo butt like you own it. But she doesn't, does she Mona? No, Spencer is just borrowing your butt. I'm the one who owns it. Oh yeah, I own your ass because I'm the one who popped your little anal cherry and claimed that fuck hole you call your ass hole as my personal property. Mine to use as I please, including pimping it out to my friends! Mmmmmmm yeahhhhhhhh, you're my anal whore Mona, and I love seeing you taking it like one."

As she spoke Alison let go of Mona's ass cheeks so she could kneel down directly in front of her bitch and taunt her. Pretty much the second she let go Spencer took over spreading those cheeks, unwilling to lose the great view she had of Mona's butt hole stretching for her, Spencer so lost in the breath-taking sight of that she didn't notice what Alison did next, or the fact that a few minutes later the kitchen door opened and her mother walked into see her daughter ass fucking another girl with a strap-on.

Spencer just couldn't help it, the sight before her was just too addictive, the brainy brunette promising herself this would not be the last time she inflicted this humiliation upon another girl.

Mona certainly felt humiliated, although that was mostly because she was loving the abuse. She hated herself for loving it, but she couldn't deny how good getting fucked up the ass felt.

Not when she moaned softly, like a total ass whore just from being anally penetrated, continued moaning joyfully as her back passage was slowly stuffed with dildo, and then as she was officially ass fucked by another girl, the third girl to do it, Mona not only moaned, but also gasped, whimpered and cried out in pure pleasure as she was once again treated like a total bottom. Oh God, how had this happen to her? She was a top, damn it. Not a bottom. Or at least, that's what Mona tried telling herself.

Deep down Mona still knew she preferred to be a top, but it was hard to convince herself she was still a pure top when she was loving it so much. Switch would be more accurate, Alison having ass fucked her so good that Mona would probably crave cock up her ass for the rest of her life. However unlike a true bottom Mona would resist the urge.

Oh yes, as soon as she got out from under Alison's thumb Mona promised herself no matter how much she wanted it she would resist the urge to be butt fucked again. Just as importantly Mona wouldn't allow herself to bottom for anyone again. Yes, she would only top, and hopefully that would repair her broken soul.

Just as she thought that Alison pressed the butt-plug against Mona's lips and ordered, "Suck it clean slut! Suck it good! Suck it clean while my friend butt fucks you! Ohhhhhhh fuck yeah Mona, oh fuck, mmmmm, that's so fucking hot!"

Mona glared up at her tormentor for a few long seconds, then Spencer gave her ass a particularly deep thrust and Mona couldn't help opening her mouth for a loud moan, Alison immediately taking advantage and stuffing the used butt-plug into her mouth. Honestly Mona was glad of that thrust as the taste of her own ass had been tickling her taste-buds to the point where she would have probably opened her mouth anyway.

At least this way she had an excuse, at least for opening her mouth. She wished she had one for moaning as she began eagerly sucking the toy clean. Which of course pleased Alison, something Mona should have taken no pleasure in doing, but to her shame she did.

"Yes, that's it Mona, suck that plug! Mmmmmmmm, clean it of your slutty little ass, while I let my friend borrow that ass which rightfully belongs to me." Ali giggled with delight, "Ohhhhhhhh yeah Mona, you're becoming such a good little bottom for me. I'm so proud of you... what are you staring at? Suck it slut!"

As usual most of Alison's words made Mona blush and desperately want to offer up some kind of retort, even though she had none. Then Alison said she was proud of her, and Mona's heart fluttered and she felt all tingly inside, and she hated herself for that more than ever before.

But then Alison looked shocked at what she had said, like those words had just slipped out, and she suddenly got defensive and pushed the butt-plug deeper into Mona's mouth. Mona briefly wondered why that was, before concluding she wouldn't analyse this and did her best to just concentrate on sucking the last of her ass cream off that toy, and after that just enjoy the wonderful butt fucking she was receiving.

"What, what is going on here?"

The abrupt interruption from Spencer's mother had Spencer freezing up, so it was a good job Alison was here to keep the plan on track, "What does it look like?"

Veronica Hastings was initially taken aback by how nonchalant Alison was about this, before quickly recovering, "I wasn't asking you... Spencer! What is the meaning of this? What the hell are you doing?"

After another pause Spencer gulped and then firmly said, "What does it look like I'm doing?"

Veronica's mouth hung open in disbelief as her daughter then pulled the dildo she was wearing out of another girl, and walked around so that the strap-on was bobbing menacingly at her. And instead of having the decency to look embarrassed or ashamed of the obscene thing that Veronica had just caught her doing Spencer came to stand in front of her as bold as brass, with another equally tooled up teen by her side.

Oh God, it was so obscene. Especially as Veronica couldn't take her eyes off of the dildo which had just pummelled the insides of poor little Mona. And before she even had a chance to get her head around this, or what had just happened, Veronica was confronted by something even worse.

"I was fucking Ali's bitch in the ass." Spencer said as if it was a normal everyday thing, "Mmmmm yeahhhhhh, I was pounding her good, and loving every minute of it. And now I'm going to do the same to you. But first, you got to get me ready. Oh yeah, on your knees Mom. Get on your knees and suck my dick!"

There was a brief pause then Alison growled, "She said on your knees!"

As she spoke Alison grabbed hold of Veronica's shoulders and pushed her down to her knees. Which shouldn't have been possible for the tall but scrawny blonde, but Veronica was just so dumbstruck by the way her own daughter was speaking to her she just couldn't resist. Then as she landed on her knees Veronica cried out, giving Spencer the opening she needed to push that big strap-on cock into her mouth.

The strap-on cock which had apparently just been inside Mona's ass, that particular revelation causing Veronica to cry out and whimper pathetically. It also should have made her spit out the cock, get to her feet and put her daughter in her place, but she didn't. Mostly because she was still too dumbstruck, but also because she loved the taste of Mona's ass, so much so she actually found herself sucking the cock.

"Wow, you were right Ali." Spencer admitted in amazement, "Wow! I, I really didn't think it would be this easy."

"That's the thing about bottoms. You just have to be firm with them, and they'll give you what you want." Alison said, staring at Mona the entire time, "Even with bottoms like your Mom. Oh yes! They might act like tops, but all they really want is someone to put them in their place. Mmmmm yeahhhhhh, and give them permission to be the sluts they've always secretly wanted to be."

Under any other circumstances Veronica would have fiercely debated such a claim, but as that would have meant taking her mouth away from that ass flavoured cock it just didn't seem worth it. Of course by just continuing to suck her daughter's dick Veronica was proving Alison's point, but there would be plenty of chances to disprove it later.

For that moment Veronica just concentrated on bobbing her head up and down that dildo, taking as much of it into her mouth as she could and then licking the last few inches clean so she could get every precious drop of butt cream. Only then did she truly realise what she had done, and by that point it felt like it was too late to stop what was happening, even as it only got worse.
