"Both sounds... intriguing, but maybe just start with a dick?"

Smiling at Kara, Blaze holds both her hands so they frame her crotch "I can do that, it will in fact be my pleasure" as she says this, the area between her hands starts to tent.
Lifting her hands and slipping the dress of her shoulders, it falls to the ground showing her in all her glory, a rising erection between her legs, and two hairless balls below it with no trace of what might have been there before.

Reaching over and grabbing Kara's hand, Blaze pulls her to her and gives her a long kiss, tongues eagerly playing with each other.
Backing up and sitting on the bed, Blaze guides Kara until she's kneeling next to her on the bed "I want to kiss you everywhere, let's get rid of this" she grabs the edge of Kara's dress and lifts it until Kara has to bend over to let her pull it off.

"Glorious, a veritable paragon of health, you're still overdressed though"

Quickly flicking open the front of Kara's bra, Blaze throws it off the bed next to the dress "Ah, there you are!" so saying, she bends forwards and starts kissing around the edges of Kara's right breast moving steadily towards the middle, while her left hand has started softly stroking her left nipple.

Between kisses she mumbles "These are wonderful little handfuls, I think I'd like another one too" as her left hand leaves Kara's breast and trails down, cupping her pussy through her panties.

"I... ooh... wait, I'll get rid of those" Kara pushes her panties down, struggling momentarily to get them over her knees in her kneeling position before throwing them to the floor.

"Eager little beaver aren't you? I know someone else who's eager" as Blaze starts kissing and sucking directly on Kara's right nipple, she takes the blondes hand and guides it down and onto her new and very eager cock.

"Oh, yeah I... a bit, um, here let me just" stuttering a bit, Kara then starts to slowly give Blaze a hand job
'Wow, this is not where I expected to find myself when I went investigating, handling the club boss' penis while she does amazing things to my breasts, if she's this good with her tongue, I'm wondering if I should've asked her to stay female.'

As they continue to kiss and fondle, Blaze leaves her breast to give Kara some deep kisses, before pushing her head down halfway to her erection, placing Kara's mouth at her breast.
However, after a few moments licking and kissing Blazes breasts, Kara feels renewed pressure on her head pushing her downwards, even as Blaze rises from sitting on the bed to kneeling.
'Oh, I guess she... she could ask, though I guess, I did ask her to grow a dick, so it only makes sense I... um... service it... heh, I get it now, getting their bottles serviced. Oh...'

As she's starting to get bent all the way down to where she's still tugging at Blazes cock, Kara sits down from her kneeling position and guides the cock towards her mouth, giving it a kiss on the tip, then a lick before taking it into her mouth.
'Oh Rao, that's... they aren't supposed to taste that great, is that what she meant by enhancing sexual reactions... I don't really care, this is great'

After a few minutes of oral ministrations, Blaze pulls Kara back from her cock "That was great princess, but I think we're both eager for the next part" so saying she pushes Kara gently backwards, until she's on her back on the bed.
'Great... just great? I did that snakelike thing with my tongue and suction that Mon-El swore rocked his world, and and... oh, she wants my feet on her shoulders, does she know I love that position or maybe she just does too? Oooh... that feels... wow'

Once she's pushed all the way inside Kara, Blaze starts to slowly build up a rhythm going in and out as she fucks her gently.
Reaching down with one hand she grabs one of Kara's hands and places it on her clit, pushing her to frig herself.

Blaze's kissing gets more and more heated, her hands rougher as her excitement increases and the fucking gets harder, but even so some of the only words that slip out of Kara in between moans over the next minutes are "Faster", "Harder" and suchlike.

Eventually, Blaze slows down and starts to raise herself up, pulling Kara along with her until a kneeling Blaze has Kara impaled on her cock with her legs resting on Blazes shoulders and using a combination of Blaze's arms and Kara's legs to bounce her up and down the hard cock as they fuck.
'Rao... oh fuck... this is too much, I can't even... fuck, I wanna'

"I'm about to cum here princess, I want...ah fuck!... I want to do it in you, what do you say Kara?"

"Oh...ah... I... fuck... yes, yes!"

Interpreting Kara's enthusiastic yes as permission, Blaze erupts into Kara's already orgasming depths.
'Oh holy fucking Rao I've never felt anything... how is it even possible to... even her cumming inside me made everything heightened... if that's how her fluids make you feel, they should package it and sell it, I'd buy in bulk'

It's a couple minutes before either of them talks "Angelica... that was just, I have no words"

"That was something else yes, I don't know what it is, but there's something about you that just feels different, heightened, I'm used to causing those feelings, not having them."

"Oh, I felt that too for sure, speaking of feeling, how on earth are you still so... well... hard?"

Looking a bit more serious, Blaze grabs onto the shoulders of the still impaled Kara and answers "I guess that's my cue for the second round of honesty, and I hope this doesn't scare you."

"I'll go first this time, I wan't you to see my true self" as she's talking, her skin is going from its original pale white to a rosy pink, then sunburn red before ending a dark red that's never been seen on any human.

While her color changes, her body grows, retaining it's proportions but expanding until she's gone from under 6' to well over 7' tall.

Kara hardly notices the increased size though, because her focus is split in two.
On the one side, there's Blaze's head, where out of her forehead jut two large and curved ebony horns, below which are her now almost glowing and white eyes lacking any iris or pupil, and at the corner of her smiling mouth her upper canines are twice the length they were, giving her smile a very predatory cast.
And on the other, she's starting to feel like she's splitting in two too, as she's gone from sitting on an just above average size human cock, to one that's now suddenly started growing to uncomfortable proportions, with distinct bumps and ridges and a head that's wider and flatter than any cock's head should be.
