Maggie Greene loved her sister, she really did. She would do anything for her. Absolutely anything. Even become her little sister's sex slave. But... she just didn't know how much more of this she could take. She loved being Beth's dyke bitch, craved all the nasty and depraved things her baby sister did to her, so much so she wasn't sure she could stop even if they were discovered, but... she was just so sore.
Her mouth, her tongue, her pussy and especially her ass, Beth used them all for her pleasure nearly non-stop, and it was exhausting, and it was painful, and worst of all she was worried her fuck holes would no longer be tight for her dominant sibling.
It had gotten to the point where Maggie cringed whenever Beth walked into whichever room she was currently in, like now for example, although the brunette had more than one reason to be nervous, the blonde looking furious as she stomped over and exclaimed, "What's this? What the hell is this?"
Swallowing Maggie began, "Beth, I owww!"
Cutting her sister off Beth slapped Maggie's ass as hard as she could and said accusingly, "What have I told you about wearing clothes?"
Briefly Maggie considered biting her tongue, it would be easier that way, but instead she asked, "What if somebody finds us?"
"I keep telling you, I'll deal with them." Beth said boldly.
"But what if it's someone we know?" Maggie pushed.
Beth smiled, and step forwards, "Than we'll tell 'em ya were teaching me about sex. I mean, that's close to the truth, ain't it?"
"BETH!" Maggie exclaimed, blushing furiously.
"Keep ya voice down!" Beth softly scolded, "Ya want the Walkers to hear us? Oh, that reminds me, I found ya a little present."
With that Beth disappeared for a minute or two and return proudly holding up a ball-gag. Seeing the device made Maggie blush again, although she had to admit that it was a good idea, especially considering how much she'd been screaming ever since she started having sex with her little sister.
Maggie had tried to keep herself quiet, but it was just impossible, especially when Beth butt fucked her, which was frequently as anal sex was easily Beth's favourite thing to do with her. And much to Maggie's shame, her favourite thing to receive from her little sister. Which was saying a lot, as she loved everything they did together.
"Go ahead, try it on." Beth said eagerly, waking Maggie from her thoughts.
Maggie hesitated, and as the smile faded from Beth's face Maggie decided just to go for it, "Seriously Beth, what are we going to do if someone finds us?"
Beth narrowed her eyes, stared at her sister for a few long seconds and then asked sternly, "Maggie, are you in charge here?"
Maggie lowered her head, and softly murmured, "No."
"Who is?" Beth pushed.
"You." Maggie admitted.
"Right." Beth said, gently pulling her big sister into her arms, "So don't worry. I'll take care of ya."
With that Beth kissed Maggie gently and forcefully, making the older sibling melt into the arms of the younger one, all of Maggie's fears and doubts melting away from the force of her baby sister's lust for her. Deep down Maggie knew this was still wrong, but when Beth was kissing her like this she just couldn't care, the small, mousey girl easily turning her back into her eager to please bitch.
So much so that when Beth broke the kiss and held the ball-gag up to Maggie's lips, the older girl didn't hesitate opening her mouth wide so the younger girl could slip the ball inside and then attach the straps tightly.
"Good girl." Beth praised, moving back to admire her handiwork for a few long seconds before ordering, "Now bend over the sink so I can properly put you in your place again."
Despite her earlier protest Maggie didn't hesitate to turn to the sink, lean forward and stick out her ass. She was totally lost in her own sinful desires, so much so that despite the fact her fuck holes were still aching and sore from the recent abuse her own sister had gleefully given them Maggie hoped that Beth would put her in her place with a nice hard strap-on fucking, especially as it meant her baby sister would fuck her up the butt.
Sadly it seemed that Beth was going to dish out her second favourite way to re-establish her dominance, although as the lesbian sex slave of her little sister Maggie would do whatever it takes to please the smaller girl.
"God Maggie, ya really do have like the best butt ever." Beth murmured dreamily, first just staring and then reaching out to grab two handfuls of those meaty cheeks, "It's just so fuck-able... and spank-able! Mmmmmmmmm, I just can't get enough. Oh yeah, I could never get enough of your hot little ass."
Beth continued taunting Maggie as she shamelessly squeezed and fondled her big sister's butt, giving it a firm smack every so often when she paused or mentioned how hot or spank-able it was. Throughout this Maggie let out the most adorable little groans and cries into her gag. They were muffled, the ball-gag doing it's job, but that just made things hotter, Beth loving every minute of this teasing.
Eventually though she started landing more frequent and harder spanks, at one point spanking her sister for a solid two minutes before reaching around, undoing Maggie's jeans and then slowly pulling them and her sister's panties down until they were around her knees.
As she slowly exposed the ass she had always secretly been obsessed with Beth felt herself almost literally drooling, and while there was technically no wetness escaping her mouth there was definitely some escaping her pussy. Oh how Beth wanted to run and get her strap-on so she could fuck this perfect ass.
But Maggie had been a bad girl and deserved to be punished, and for that Beth was going to put a little colour in those cheeks. After a little more groping of course, Beth unable to resist grabbing that ass and giving it a few playful squeezes now it was bare before raising her hand and then bringing it down as hard as she could on Maggie's sexy little butt.
For a few minutes she delivered one hard strike after another, but then went right back to groping her older sister's ass, leaving plenty of times in between blows to massage the pain away.
Then she gradually cut down on her groping time in favour of more frequent smacks until there was no pause between them at all and Beth was relentlessly beating her big sister's butt, making Maggie squeal, whimper and cry into her gag. It also made her meaty cheeks jiggle hypnotically and the once flawless skin to turn bright pink, then a dark pink, than a cute little red which practically made Beth drool.
Part of Beth wanted to keep going. Because sure, her hand stung a bit, but she'd experienced worse and it was nowhere near to the pain she was causing her bossy sister, and she really wanted to make Maggie's ass a bruised and dark red.
But if she kept giving Maggie everything she had then there would be nothing left for when her big sister really fucked up, and while part of Beth wanted to keep spanking Maggie forever another part of her desperately wanted to fuck. Oh yes, Beth's pussy was aching for some attention, and she was going to get it. Specifically via her older sister's talented little tongue.
Maggie was bigger and stronger than her petite lover/sister, and as she lay there over the sink getting her ass whooped she couldn't avoid thinking about how she should be able to stop this without much trouble. More importantly she should stop this, because being her baby sister's sex slave was gross and wrong, but Maggie just couldn't stop herself.
Being dominated by Beth was intoxicating, so much so that Maggie enjoyed every hard blow to her butt, the brunette happy to lay there all day while the blonde beat her ass until she couldn't sit down no more. But luckily for her it didn't come to that, although it made her nervous the way Beth just suddenly stopped and then stayed silent.
Then after maybe about a minute, although it felt a lot longer, there was some movement behind her, Maggie glancing back to see that Beth had pulled her pants and panties down around her ankles, exposing her cute little wet pussy. It was wrong, but Maggie immediately felt her mouth water at the memory of the taste of her little sister's pussy.
