*****

"Okay, okay, I'm coming." Iris called out, sighing deeply as she quickened her pace towards her front door and then opened it, stupidly without looking through the keyhole, "What do you OH MY GOD!"

"Surprise." Caitlin beamed.

That was the understatement of the century, which Iris might have quipped if for once she wasn't completely speechless. Because here in front of her was Caitlin Snow, looking exactly how she was when they first met. Her hair and eyes were brown, her skin was no longer sickly pale and her lips were red and inviting.

So inviting it was all Iris could do not to smash her lips against them. But even though they were dating she still wanted to get clear permission first, considering the circumstances last time she saw this woman. Besides, her curiosity got the better of her, forcing her out of her stunned state to the point where she had so many questions she wasn't sure what to ask first.

In the end Iris simply croaked, "How?"

Caitlin lifted up her hands and showed the other girl her new accessories, "Cisco made these for me. They dampen meta-human powers. And yes, he came up with the idea before, you know, I changed, but he wanted to run a whole bunch of tests before showing them to me. And I wanted to make absolutely sure they would work every time with no lasting side-effects. Because, because I just couldn't bear the thought of telling you about these and then not being able to use them without hurting you. Or worse, trying and, and... you know..."

There was a brief pause and then Iris asked, "So we can..."

"Yeah. I'm 100% sure." Caitlin smiled proudly, and then hesitated, "Well, more like 99.99%, because no matter how sure you are there is always the chance that-"

Before Caitlin could finish Iris grabbed her girlfriend, roughly pulled her inside the apartment, slammed the door and then push the other girl up against the nearest wall and did the one thing she wanted to do above everything else but couldn't for the last few weeks, kiss Caitlin Snow right on the mouth. Unlike some kisses she had in the past this was totally worth the wait, as all the movie clichés seem to happen at once.

Her heart skipped a beat, she seemed to melt into the other girl and she swore she could hear birds singing. At least when Caitlin got with the program and started kissing her back, the scientist at first acting like this was some big surprise when obviously she had been planning this for quite a while.

Iris planned to make her pay for that sometime in the near future, but for now she simply massaged Caitlin's lips with her own and got completely lost in this wonderful act of mutual affection. To her delight Caitlin got just as lost, pulling Iris even closer into her and opening her mouth to allow Iris to push her tongue inside. Or Iris might have pushed herself even more firmly against Caitlin and forced her tongue into her mouth.

Honestly it was hard to tell as she was so lost in the moment. She was fairly certain it was a combination of both, but just in case she pulled back to see if she was rushing things too much or doing something Caitlin didn't like.

For a brief moment the two women stared at each other, then Caitlin smiled widely. Iris did the same and they shared a brief laugh of relief before pressing their lips together again, and even though they added their tongues almost immediately this time the kiss remained soft and gentle. They also gently caressed each other, sliding their hands over each other's arms, sides, backs and faces while avoiding all the really fun parts.

At least for now. Iris wanted to do more, but didn't want to overwhelm Caitlin if she wasn't ready for it. So instead she eventually broke the kiss, smiled at her lover again who returned it, and then gently pulled her further into her apartment while asking her some more questions.

"So, what kind of tests?" Iris grinned.

"Uh?" Caitlin replied, still a little dazed.

"What kinds of tested you run?" Iris gently pushed, before grinning, "Did you kiss any frogs?"

Looking bashful Caitlin shook her head, "No frogs."

Iris frowned, "Rats?"

"What? No!" Caitlin frowned.

"Well what then?" Iris pushed, and then when Caitlin looked hesitant she softly pleaded, "Tell me. Please? I promise, this is strictly off the record. I would never do that to you. But, I need to know."

There was a long silence and then Caitlin took a deep breath, "I kissed the last guy who tried to kill you. It was when I was 95% sure it wouldn't kill him, but I had Cisco keep a close eye on him for the past week or two, just in case there was a delayed reaction, but I'm fairly certain that if it was going to happen it would have happened by now."

"Wow." Iris murmured.

"It... it's not something I'm proud of." Caitlin stammered quickly.

"Hey, I get it." Iris reassured softly and swiftly, "There's no judgement here. But-"

"It's still a big risk, I know." Caitlin said solemnly.

"Well yeah..." Iris smiled, "And I want to be with you, completely, but I would hate to think of you crossing a line you can't come back from just for me."

"Oh, I definitely did it for me. Mostly." Caitlin admitted, leaning in slightly as she continued softly, "I really, really wanted to kiss you."

Iris smiled, leaned forward slightly so they could briefly kiss before she pulled back and asked, "So if you take these things off, do you..."

"Get frosty again? Yeah." Caitlin giggled, "But I'm in no hurry to do that."

"I get that." Iris nodded, "I just don't want to think you were giving up being a superhero just because you wanted to kiss me. "

Ignoring the superhero part Caitlin said as confidently as she could, "That's not all I wanted."

"Yeah?" Iris smiled.

"Yeah." Caitlin confirmed, taking a deep breath before whispering, "I, I wanted... I want to slide my lips all over your amazing body."

There was a moment's pause, then Iris admitted, "I want to see just how warm your beautiful body is."

Another pause, then Caitlin offered, "Bedroom?"

"Bedroom." Iris confirmed with the smile.

The two women then got up and Caitlin offered her hand which Iris quickly took, prompting another smile and even a giggle as Caitlin gently pulled Iris into the bedroom. Feeling more confident than usual Caitlin then pulled Iris into a deep and passionate kiss.

She even pushed her tongue into Iris's mouth, although Caitlin lost the tongue battle almost as quickly as she lost her shirt, the two girls made quick work of each other's clothes as they continued to make out. Then Iris broke the kiss, gave her the smile which always made Caitlin melt, no matter how cold she felt lately, and then positioned herself in the centre of the bed.

"As much as I love kissing you..." Iris said flirtatiously after breaking the kiss, completing the line after she was in position on the bed, "I think you said something about wanting to slide your lips all over my amazing body."

"Wow." Caitlin murmured softly, although to softly because combined with that and Caitlin staring at her Iris clearly got the wrong idea.

"Or I could just slide my lips over your hot little body if you want. I don't mind." Iris said.

"What? No!" Caitlin stammered, quickly snapping herself out of her daze, "I, I mean I don't mind either, but I definitely want to fuck you. It's just that, you're so, so beautiful."

"Thanks." Iris smiled softly, curling her finger in invitation, as she added, "Now, why don't you prove it by pressing that hot little body of yours down on top of me and kissing me again?"

Caitlin smiled, "I can do that."

Unable to resist Iris added, "And that's hot figuratively and literally."

"I know." Caitlin said dryly.

Despite herself Caitlin couldn't help but giggle after that, Iris joining her for a brief second before Caitlin climbed onto the bed. Then the giggling very quickly went away as Caitlin slowly crawled up Iris's body until they once again face to face, Caitlin's now once again warm body pressed down against Iris's equally warm body.

For a moment Caitlin just enjoyed that fact before pressing one long lingering kiss against Iris's lips, this one far more gentle and romantic than the rough and needy kiss which had proceeded it. And she worked her way down Iris's jaw to her neck and lingered there for a little while as her hands roamed Iris's body.

It was a little awkward with the power dampening bracelets still on. Make that a lot awkward, but totally worth it for the peace of mind that she wouldn't hurt her girlfriend. Well, 99.99% sure she wouldn't. Because Caitlin was now a freak of nature she could never be 100% sure again that she wouldn't hurt someone she cared about, and thankfully Iris loved her enough to know how selfish she was being by allowing their relationship to continue.

So Caitlin could ignore that Iris seemed a little nervous, no doubt sharing her apprehension about the bracelets, although Caitlin did her best to take her mind off it first by kissing her lips, then her neck, and ultimately her tits. Well, she planned to go lower, but Iris's breasts definitely deserved some attention.

At first Caitlin had teased Iris by kissing her way down her lover's body, up one of her boobs and then concentrating on the area around the nipple for a long time before taking it into her mouth. Then she sucked it only briefly before moving over to the other.

Caitlin then repeated this process a few times before gradually increasing the force of her suction, along the way beginning to slide her tongue around those nipples which particularly had Iris crying out in pleasure. Oh God, it felt so good to be pleasing Iris with her mouth, although Caitlin probably didn't give her girlfriend's tits the attention they deserved because she was so eager to get to the next part. Luckily Iris seemed to feel the same way.

"Lower baby. Mmmmm, lower." Iris moaned softly, "Ooooooh, you know what I want. I've wanted it for months. No, that's not true. Oh God, I've wanted it since we met!"

"Me too." Caitlin admitted.

"Then do it baby." Iris smiled softly, before explicitly telling her girlfriend to, "Eat my pussy. Ohhhhhh, please Cait. Eat it."

"Gladly." Caitlin whispered into Iris's flat stomach, already halfway down it.

Iris closed her eyes, partly to intensify the anticipation and partly because it was a bit overwhelming seeing long brunette locks slowly making their way down her body. Fucking Caitlin in her Killer Frost form had been one thing, but this was different. Before it was almost like she was with a completely different person, now she really was having sex with a friend.

Which of course was stupid. She been doing that for months now, but because Caitlin looked like her old self again it just made her think about how this was a girl she had known for years, had cared for Barry when he was in the coma and then help him save the city, and even save the world. Had saved her. Had saved herself. And now she, Caitlin Snow, was going down on her.

Things only became more intense when it actually happened, Caitlin reaching her destination and after a brief hesitation sliding her tongue slowly over Iris's pussy lips, working her way from the very bottom to the very top and then repeating the process, Caitlin Snow beginning to lick her pussy with a slow but steady rhythm.

Which made Iris open her eyes wide and let out a long loud cry, followed by a series of happy moans. Then she looked down to see her former best female friend in between her legs. Her girlfriend. Caitlin was now her girlfriend, and she was finally in between her legs and licking her pussy like Iris had wanted pretty much from day one.

She definitely hadn't been lying about that part as even before her first and only time with Linda the first time Iris had seen Caitlin she had thought she was beautiful. And after a brief conversation in which Caitlin had proven to be smart, good at her job and most importantly determined to help Barry not only was Iris put at ease but she found her initial attraction blossom into genuine curiosity, which had only grown since they had got to know each other.

Initially Iris hadn't thought anything would come of it, but after a brief affair with Linda and Caitlin becoming even more attractive now she was a superhero Iris just hadn't been able to resist when the opportunity presented itself, and she was so glad she hadn't.

While Caitlin wasn't quite as confident or experienced as Linda had been their relationship had made it that much more intense. Also there was something to be said for the way that Caitlin looked up at her for approval every so often, looking so bashful yet hopeful that Iris couldn't help but encourage her a little more than she already was, which was saying something.

To be fair Caitlin was doing a good job of teasing her clit, at first mostly ignoring it and then touching it with every other lick so as not to overwhelm Iris too soon, and slowly build up the pleasure until ultimately Iris would beg for more, even if she had time to hold off as long as possible so she could savour this wonderful sensation.

Caitlin was definitely trying to savour this. After all this was her first time eating pussy, and while there had been a time she had thought she wouldn't like it, or at least been sceptical, that ended as soon as she started having sex with Iris West. As soon as she had crossed that line getting to return the favour was one of the main reasons Caitlin wanted to find a way to change back to her 'normal' form.

When she was stuck in her Killer Frost form Caitlin couldn't take the risk of her ice cold lips around that much warm liquid as it seemed almost inevitable she would cause the woman she was falling for agonising pain, but now she had her new fashion accessories everything was going better than she could have possibly hoped.

Not only did she love the taste of Iris's pussy but she actually had the other girl moaning in pure pleasure at what she was doing, a clear sign that she was doing well. Although Caitlin regularly looked upwards just to make it clear, as she was paranoid that at best her inexperience would have Iris taking pity on her and faking her enthusiasm.

That was still possible, although the smile she got from Iris certainly seemed genuine, and Caitlin often found herself looking up just so she could receive another because each one made her heart flutter. Of course her main focus was pleasing Iris, Caitlin desperately trying to remember everything she'd read on the Internet about performing cunnilingus, and more importantly everything she'd learned from Iris going down on her.

She started by teasing Iris's clit, slowly showing it more and more attention as time went on, initially just with her tongue but then again eventually Caitlin wrapped her lips around the other girl's clit and gently sucked it for a few long seconds. This unsurprisingly caused Iris to gasp loudly in pleasure.

Somewhat surprisingly it also caused her to reach down, grabbed hold of Caitlin's hair and push her more firmly against her pussy. Not that Caitlin was complaining. Exactly the opposite in fact, and this gave her just another way of knowing how well she was doing. And Iris didn't hesitate to use it, even occasionally taking control by tugging her this way and that, which Caitlin especially loved.

At the beginning she was tugging her away from her clit when, Caitlin assumed from her experience, it got too sensitive and Caitlin was giving it just a bit too much attention, but it wasn't long before Iris was pushing her against her clit for longer. Caitlin was happy to oblige with a longer suction, and eventually even one with more force behind it, both of which definitely got the positive reactions she was craving.

But then Iris started pushing her lower, and taking a judgement call Caitlin denied her girlfriend what she clearly wanted for now, which clearly annoyed Iris but Caitlin was positive it would work out in the long run. Besides, Iris was a shameless tease, so it was about time Caitlin got a little payback.

Iris was amused by this at first, and somewhat grateful as it would just mean her eventual climax would be that much more powerful. Also, it was just nice to drag this out a little bit, considering this was a first for them, and it was only the second time another girl had gone down on Iris.

So yeah, Iris was all for not rushing this. But at the same time Caitlin was almost too good at easing her, and inevitably she wanted more. For a while she forced that ever increasing desire, partly to allow Caitlin her revenge, but mostly to savour the moment. Of course there was a limit to what anyone can take, and Iris reached hers when she not so subtly encouraged Caitlin to tongue fuck her and the other girl continued to insist on denying her.

"More! Give me more, mmmmmm, come on Caitlin, fuck me." Iris moaned softly, "Fuck me and make me cum. Ooooooooh yessssss, stick your tongue inside me and fuck me with it. Yeah, tongue fuck me, fuck, oh yes, just like that, ohhhhhhhh fuckkkkkkk yeahhhhhhhh FUCK ME! Oh Caitlin, ooooooooohhhhhhhh Goooooooooddddddddd!"

To Iris's surprise, and delight, she really didn't have to say much to get what she wanted. In fact the second that she actually said what she wanted in detail Caitlin started concentrating her licks on Iris's instructions, and then a second or two after that she began slowly pushing her tongue into her pussy, rendering Iris completely incoherent.

Not that she fought very hard to remain coherent, as it was clear no more words were really needed. Iris continuing to provide encouragement to Caitlin for the fun of it, and to build up her girlfriend's fragile self-esteem, but otherwise she was completely concentrating on her own selfish pleasure.

Of course Iris West was no pillow princess, and fully intended to return the favour once Caitlin had gifted her with an orgasm. Or ideally a few of them, which didn't feel like it would take much given that Iris almost came from just the penetration, and as soon as the tongue fucking began it was pretty clear that she would soon have the opportunity to return the favour.

More or less. Iris was tempted to literally, as she did love going down on Caitlin, but there was something she had been eager to try, and this special night felt perfect for it. And for better or for worse just thinking about it bought Iris even closer to the opportunity as she imagined taking Caitlin that way.

For a little while Iris held back just to build up her pleasure and savour being on the edge of orgasm, but Caitlin wouldn't be denied, and soon Iris found herself cumming in another girl's mouth was second time in her life. And more importantly into Caitlin's mouth. Oh yes, Iris was cumming into the cute little mouth of Caitlin Snow, fulfilling one of the most frequent fantasies for the past few years.

To make this dream come true even better she focused on the pretty brown haired white girl between her legs as Caitlin further impressed her by making her cum over and over again, just like she hoped she would do. And hopefully would do again.

Caitlin desperately tried to swallow every drop of Iris's cum, but there was just so much of it and it wasn't like she had any previous experience doing this so a lot of it ended up on her face. Which made her whimper pathetically, because this was like the best tasting thing ever.

It was heaven in liquid form, and Caitlin was now furious with herself for not doing it the second Cisco finished making the power dampening bracelets. Okay, no she didn't, but she had wished she had completed the testing a lot sooner. But no, she had to play hero, and waste her time sleeping and eating, when she should have been fixing her powers so she could finally go down on Iris West and swallow her cum. Or at least as much of it as she could get.
