Willa thought it would be easier to get that damn gun, but Wynonna kept it close to her at all times, even when she was sleeping. It took Wynonna ages to stop fucking Waverly long enough to sleep, finally giving Willa a chance to sneak in and steal it from her, only to end up accidentally waking her sisters and then having to lie about having a nightmare.
Which was meant to get her out of it, but it only ended up with her in bed being part of cuddling, which wasn't nearly as interesting or fun as being involved in the sex. So clearly Willa needed another strategy, something which would really distract Wynonna, or at least wear her out. And ideally be more fun than what they had been doing lately.
Luckily she came up with the perfect thing, and when she did Willa practically ran into the living room to tell her siblings. Once she got there, she wrinkled her nose up as she found Waverly sitting on Wynonna's lap, the two of them giggling and kissing like the most sickeningly in love couple they were. Fuck, it was so disturbing to see them flaunt their incestuous relationship.
Which some might think of as ironic, considering Willa's relationship with the Demon, but that was good and wholesome compared to this atrocity. But Willa did her best to hide her true feelings as Waverly reluctantly broke the kiss and her two sisters turned to look at her.
"Can we help you?" Waverly asked.
"Well... I know we agreed that me joining your relationship was your call, and I totally respect your decision." Willa said as convincingly as she could while approaching.
"But?" Waverly frowned.
"No but." Willa lied, "I really do respect the decision... but, what if I gave you another offer?"
"What kind of offer?" Wynonna frowned, and then when Waverly glared at her she protested, "What? We might as well hear her out."
"Well said, sis." Willa said, taking a seat on the couch next to them and then taking Wynonna's hand in both of hers, "I know what you have with Waverly is special, but can you honestly say it really satisfies you? Because sure, you might like topping a total bottom like her, but you're not a total top. No, you like it both ways. Guys and girls, top and bottom. Or do you remember how easily I topped you?"
"Waverly is enough." Wynonna said simply, learning from her earlier mistake, "More than. I mean sure, yeah, I like both, but I choose Waverly. I will always choose Waverly."
"What if you didn't have too?" Willa pushed.
"Meaning?" Waverly frowned suspiciously.
"Well, I know Wynonna got it into her head that we need to be one big happy family, and maybe that would work best for her, but not for us. Not for me." Willa said truthfully, before beginning to bend the truth, "I love you both, I really do. But I'm not in love with you. I love you in a way a sister shouldn't, but it's not the same as what you guys feel for each other."
"Damn right it's not." Waverly grumbled.
Ignoring her younger sibling Willa continued, "But Wynonna is going to screw up. She always does, and already has. First by screwing me without Waverly's consent, next, who knows? I know, I know, I know, don't interrupt Wynonna. I know you love Waverly, and will try really, really hard not to mess up again, but you can't guarantee it, and you know it. So how about a precaution? A previously agreed on arrangement where whenever Wynonna feels the urge to get dominated and fucked, she comes to me. Not some random guy at a bar who might be a Demon, or have an STD, or worse be clingy. And Wynonna wouldn't have to swallow her pride and convinced that ginger butch to top her. No, she'd have her family to take care of her, just the way she always wants. Best of all, I would understand where Waverly would be with this. Either helping me fuck her, or just watching."
There was a brief pause and then Waverly asked, "What makes you think Wynonna wants to be topped? Because she ate your pussy while you were being mean? That's nothing. She goes down on me all the time, only I'm not a bitch about it. And she wasn't interested in letting Nicole top her at all."
"She let me top her." Willa smirked, then clarified before Waverly could say anything else, "She let me fist her, and I could tell she wanted more."
Turning her attention back to her middle sister Waverly asked, "Wynonna, is that true?"
Wynonna bit her lip for a few long seconds, and then quickly reassured, "Waves, I know I screwed up last time, but I'll never do that again. I swear. You're enough. End of story."
Another pause and then Waverly pushed, "Is this something you want?"
"Not if it costs me you." Wynonna quickly protested, and then when Waverly just stared at her for a few long seconds she lowered her head and admitted, "But if it didn't... yeah. It's something I'd want."
Yet another pause, this one the longest yet as Waverly was clearly debating, and then the youngest Earp softly said, "Okay."
Lifting her head Wynonna checked, "Okay?"
"Okay." Waverly repeated, smiled softly, "I'd do anything to make you happy."
"Oh Waverly!" Wynonna exclaimed happily, kissing all over her own sister's face making them both giggle before she added, "You're the best girlfriend ever."
"And don't you forget it?" Waverly grinned, leaning down for another deep kiss with her beloved middle sister.
Willa was then forced to watch the obscene sight of her sisters kissing for a few long seconds before she cleared her throat to get their attention and then told them, "Yes, well... how about a trial run? You know, to seal the deal?"
"What did you have in mind?" Wynonna grinned.
"An ass fucking." Willa admitted, before explaining, "Think about it, what better way than to solidify our new arrangement then you bending over like a little bitch and taking it up the ass for me?"
"I... I guess." Wynonna stammered and blushed.
"What? It's not like you've never done it before." Willa pointed out before Wynonna gave a look causing her to frown, "Wait, really? Never?"
"Nope." Wynonna admitted bashfully, "I was always more a butt fucker than a butt fuckee. More than happy to give, but never to receive."
"Even with guys?" Waverly asked out of curiosity.
"No." Wynonna laughed, "I offered every time they did, which normally shut them up fast, but I never liked any of them enough to do it any possible way. But girls? I love butt fucking girls. Especially when they looked like you. And to actually get to fuck you in the butt, oh Waverly, that's pure fucking heaven."
"But you're curious about being on the receiving end?" Willa jumped on the opportunity, "But not for the ginger bitch, or even your precious Waverly?"
"Waverly's a natural bottom." Wynonna shrugged, "And Nicole, who isn't that bad BTW, wasn't interested in me."
"And even if she was, she wouldn't be dominant enough for you. Not like me." Willa added, the look on Wynonna's face telling her she was right, "Well, I can't think of a better time to give you a taste of your own medicine."
"If she doesn't like it, you'll stop?" Waverly checked.
"Of course." Willa said dismissively, before promising, "But she won't, will you Wynonna?"
