"Okay, let's get out of here." Caitlin Snow beamed at her success.
"Just a sec Caity." Killer Frost grinned wickedly, "I wanna alter our little deal."
"What? No!" Caitlin panicked, "We don't have time for this. Zoom could literally be back any second."
"So let's make this quick." Killer Frost beamed, "Have you ever eaten pussy Caity?"
"What?" Caitlin exclaimed.
"You know, pussy? Cunt? Fuck hole? Whatever you want to call the thing between our legs." Killer Frost explained crudely, and somehow like she was talking to a child, "Well, have you?"
"N, no." Caitlin stammered.
"Huh." Killer Frost murmured, "I'm not usually one for the girl-girl scene either, but it was easily the best part of college, and what can I say, you're really cute."
"Erm, thanks." Caitlin blushed, "But I'm not gay."
"Oh sweetie, neither am I." Killer Frost grinned, "But I just can't let an opportunity like this pass me by. So, call it masturbation if you want, but we will be fucking tonight. If we have to get out of here, which is up to you."
Caitlin stared at her doppelgänger for a few long seconds in disbelief. She couldn't remember the last time she was hit on so crudely, and certainly it had never been by women. Any woman for that matter. She had occasionally wondered about it, but she always had a boyfriend in college. Actually it had been that way since high school, as while she was a little socially awkward she fell under the category of 'hot nerd', and was hit on constantly.
But this was new, and honestly a little flattering, although it was super weird considering it was herself from another world who was doing it. For that reason she couldn't possibly say yes, but they couldn't possibly stay here, so after a few long seconds Caitlin chose the lesser of two evils.
"Alright fine!" Caitlin grumbled, "Can we go now?"
"Absolutely." Killer Frost grinned, grabbing a hold of Caitlin and then telling her, "Hold on tight."
With that Killer Frost lifted her up slowly and started running towards the cave opening, Caitlin doing as she was told and holding on tight as she feared the villain was about to throw her over the edge. Instead she jumped over the edge, Caitlin holding to her even tighter and becoming angry as she feared that the crazy bitch had just killed them both.
Then Killer Frost held out her hand, which glowed blue, and a long strip of ice appeared in front of them, allowing them to slide down to safety. Honestly it was kind of hot, especially as Killer Frost kept it going for a little while, giving them the illusion of flying, and the ice even evaporated into nothing as they went, meaning there would be no trail left behind.
For a few happy moments Caitlin thought that Killer Frost would set them down far away from here, ideally in a highly populated area, where they could blend into the crowd. Or at least she could. Which would have been the smart thing to do as far as she was concerned, but instead she found herself in another cave, albeit far away from the one they had just been in.
Scowling angrily Caitlin opened her mouth to protest, but before she could Killer Frost covered her lips with her own and started kissing the doubt out of her. Again Caitlin thought she was about to die, but before her body temperature dropped to a dangerous degree Killer Frost pulled back, leaving Caitlin gasping for breath.
"Let's get something straight, so to speak." Killer Frost quipped, "We had a deal, and I expect you to honour it. If you don't, well... if you're not going to satisfy me in one way, I can always get another type of satisfaction out of you. Understand?"
Caitlin nodded quickly, "Y, yes."
"So what are you going to do?" Killer Frost pushed.
Caitlin blushed, "Eat your pussy?"
"Wrong, you're going to give me the best head of my life." Killer Frost gleefully corrected, before pushing Caitlin to her knees, "Now get to work, and don't make me asked twice."
Whimpering softly Caitlin waited a few seconds for Killer Frost to start taking off her clothes, and then when her mirror image just stared at her expectantly she rushed to undo the other woman's pants and pull them down. It was hard to do it with trembling fingers, but Caitlin was used to working under stressful conditions, and always got the job done.
Of course when Killer Frost's pants and panties were down around her ankles Caitlin paused again and looked up hesitantly at her doppelgänger as she tried to figure out exactly what the other woman wanted. Or more accurately, exactly how she should give Killer Frost exactly what she wanted, which was potentially very difficult seeing as she'd never done this before.
Killer Frost would normally get frustrated at this point, let out a groan of annoyance, and then grab her lover's head and shove them face first into her pussy. But there was just something endearing about watching her mirror image seem so nervous about doing anything sexual, when Killer Frost had always dived head first into sex regardless of how inexperienced she was.
It was a little reminder of just how different they were, so different that it was hard to believe they were basically the same person, just from different worlds. But, she'd never admit this out loud, but this version of her was smarter than her, which meant sooner or later Killer Frost would get what she wanted. And when she did, it would likely be better than any college girl she'd ever been with.
Sure enough after a few long seconds of hesitation the brunette lent forward, closed her eyes, stuck out her tongue and slid it over the white haired girl's pussy. The lick stopped before it reached her clit, which was disappointing, but the nervousness more than made up for it. Oh yes, maybe Killer Frost should do this more often? After all, there were plenty of girls she would like to make eat her pussy. Or ass.
Like that annoying Detective, Iris West. Oh yes, Killer Frost could picture it now. Getting that smug bitch who pointed a gun at her on her knees and shove her face first into her pussy, or ass, or one then the other. Oh yes, Killer Frost particularly like the sound of that last one.
For a few blissful moments Killer Frost became lost in those fantasies while her mirror image cautiously repeated that first initial lick, which was just as nervous as the last. That process was repeated a few times, but then without even being aware of it Killer Frost began softly moaning, giving Caitlin the confidence to slide her tongue further upwards to brush against the other woman's clit.
That really got Killer Frost's attention, her eyes going wide as she let out a loud cry of pleasure. Which was then followed by a few more as the brunette repeated those licks, much to the delight of the white haired girl. So much so that she actually started to give her some encouragement.
