Waverly Earp cried out in panic as she was suddenly awoken by something landing on her. As anyone would she freaked out for a few long seconds, then anger replaced fear as she realised it was her sister on top of her. But that was where the normality ceased, because while Waverly vaguely remembered being rudely awaken by Wynonna when they were kids it had never been while they were both naked.
Not that Waverly could remember getting naked last night. Although she did remember a lot of terrifying things, and she finally realised her sibling's eyes were pitch black, meaning this was the second time she was waking to find herself face to face with the Demon possessing her big sister's body.
"Good morning lover." Bad Wynonna greeted wickedly, "Ooooooh, you have no idea just how long Wynonna Earp has wanted to say that."
Initially Waverly blushed at those words, but it was just an automatic reaction. She wasn't ashamed. She wasn't! What happened last night hadn't taking place under the best of circumstances, certainly not the ones that Waverly had dreamt of, but it was beautiful.
Two people who loved each other unconditionally expressing their love for each other in the most intimate way imaginable, ignoring what most people thought of as wrong and just being true to themselves. She would not let this creature or anyone else turn that into something ugly. Not under any circumstances. So Waverly puffed up her chest, summoned every ounce of bravery she had, and gave the evil creature a piece of her mind.
"Me too." Waverly said firmly, "Because I've wanted to hear that my entire life."
Bad Wynonna just stared her pray for a few long seconds, and then burst out laughing, "Oh that's precious."
"That's love." Waverly said.
After another fit of laughter Bad Wynonna suddenly became serious and growled, "You'll burn for it."
"I don't believe you." Waverly said defiantly, "I don't believe God cares who we love, as long as it's pure, like love between me and Wynonna."
"Oh sweetie, there is no God. Only Devils." Bad Wynonna chuckled evilly.
"Like I'd actually believe anything you say." Waverly grumbled.
"Well, telling the truth is more fun. It hurts a whole lot more." Bad Wynonna grinned, "For example, what would your friends think about all this? Huh? Or how about what's left of your family? Or better yet, your precious Nicole? What will your little girlfriend think when she finds out her sweet, innocent Waverly is a filthy little sister fucker."
It was hard for Waverly to answer, as she didn't know the answer to that, but for now she defiantly replied, "It doesn't matter. All that matters is Wynonna and I love each other."
"Awww, you really believe that, don't you?" Bad Wynonna chuckled evilly, "Well why don't you show me. Mmmmmm yeahhhhhh, I'm sick of debating. I want to have some fun. That's why I took this body. To have some fun. And, why I took care of your clothes."
With another evil chuckle Bad Wynonna grabbed something, which turned out to be pieces of fabric, which Waverly realised was all that remained of her clothes, the other brunette letting it slip through her fingers to beside Waverly's head insultingly. It was a pity, Waverly had liked that outfit, but she had more pressing concerns. Mostly her own, and her sisters, survival.
But while it wasn't exactly how she wanted it this creature was still offering her sex with her sister, which was certainly enough to get Waverly's attention. Especially as she became suddenly very aware of her big sister's naked body on top of her, complete with their hard nipples pressing into each other's boobs and their wet pussies resting against each other.
She had been too afraid and angry to really concentrate on it before, but now Waverly couldn't think of anything else, especially as the evil creature started grinding down on top of her, rubbing the most sensitive parts of her body against hers. Oh God, Wynonna's tits and pussy were rubbing against hers, causing Waverly to a little cry.
As long as she kept her eyes closed and focused on the fact that this was her big sister, and not the fact that Wynonna wasn't in the driver seat. Of course the evil Demon couldn't allow her to continue that fantasy for long, cackling wickedly in that not quite human voice, and then using it to taunt her again.
"You like that, huh Waves?" Bad Wynonna gleefully taunted, "You like feeling your big sister's naked body rubbing against yours? Huh? Mmmmm, yeah you do. I can feel just how wet you are. And you can feel it too can't you Waverly? Just how wet I am for you? How wet Wynonna is for you? Mmmmm, how wet you make your big sister? Huh? Yeahhhhh you do, mmmmm fuck! You-"
