Enhancement, or corruption?

Alexa adjusted her glasses to look at the vial of pinkish liquid on the bench in front of her. “What did you say this was, again?” She asked, looking up to her friend across.

“A little something I found in a dusty old tome.” Mary explained. “A wise woman named Catherine of Bordeaux came up with it. The potion’s meant to… enhance the body.”

“Really?” Alexa muttered. “How do you know it--?”

“I already took it.” Mary said, standing up. That was when Alexa’s jaw dropped. Mary had definitely been… enhanced. Her breasts, once a B cup, were now solid Ds in the low-cut top she now wore. Her ass had grown larger too, shaped nicely in her pants. The last time Alexa had seen her brunette friend, she was wearing a baggy sweatshirt and jeans, sitting off to the side of their occult group, not hardly speaking. However, the woman before her now was positively transformed. Alexa blushed slightly, cursing her own bisexuality. She had to admit, Mary looked DAMNED good. Other people seemed to notice too, passersby glancing at the woman as they walked by, some less subtly than others.

“So… so why invite me here now?” Alexa asked, trying not to stare at Mary’s new boobs. “Why not tell everyone about it at the next meet?”

“I thought it could stay between us, for now.” Mary responded. “I could only make two doses, and the ingredients are, uh, hard to come by. We’ll make more soon for the rest of the group, but I figured you should have the first taste.”

“Me? Wh-why me?” Alexa stammered nervously.

Mary gave her an indescribable look: almost playful faux-innocence. “Us girls have to stick together, don’t we?” She said, winking a little. “But you don’t have to take it if you don’t want to…”

Alexa thought about that for a minute. It wasn’t just Mary’s body that was different; her entire demeanor had changed. She was undoubtably more confident, carrying herself with a different air than before. Of course, the bookish woman was naturally suspicious of this miracle potion Mary was now offering, but in the time they’d known each other she’d never known Mary to lie.

“…and you’re sure there aren’t any weird side effects? This isn’t gonna be like **** Becomes Her, is it?” She asked.

Mary shook her head. “Catherine of Bordeaux was a master of alchemy. I looked into this for a long time, and there don’t seem to be any issues among the many women who took it. The only side effect is that it makes you horny for the first couple days, but that seems to be about it.”

Alexa gulped. That was it? Mary did seem to know what she was talking about, and those curves… Could it really be that simple? She had to know. She wasn’t ashamed of her own body, but she couldn’t deny she had room for improvement.

“What the hell.” Alexa decided, grabbing the potion. “What’s the point in being in this fucking group if we’re not gonna get anything out of it? It’s not like we’re finding any demons lately.” Mary grinned devilishly as she watched her friend take a swig.

Almost immediately Alexa was overwhelmed by the taste of it. It tasted GOOD. Like, amazingly good. The best smoothie she’d ever had, times a million. Before she knew it she was drinking more of it down, then more, then more until she’d finished the entire thig in one huge chug. “Holy fucking shit!” She exclaimed.

“I know, right?!” Mary agreed. “I liked it too.”

Alexa sat for a moment, looking around in anticipation. “I don’t feel any different.” She remarked.

“Well, it takes a while for the changes to start, silly. You think these grew out in one minute?” Mary pointed to her tits. Alexa looked this time, and found herself continuing to look.

The buxom brunette noticed. “My eyes are up here, Lexi”. She joked.

“Sorry. I think the uh… side effects are starting, at least.” The bookish girl said, looking back down and away.

Mary smirked. “That’s quite alright.” She sat down right next to Alexa on the bench. “I’m starting to like the attention, I think. From men…”

A hand laid on Alexa’s leg.

“…And from women. If you’d like, we can head back to my place, get to know each other a bit better?”

Holy shit. Holy shit holy shit holy shit. Alexa stood quickly, taking a few steps away from Mary. “Um, that’s nice, but uh, y’know, I think I’ll just uh, call you if I have an issue, ok?” Alexa stammered out quickly.

“No problem.” Mary said casually, as if she hadn’t just openly propositioned her friend. “I’ll be in touch. Let me know how you get along Lexi.”

“Umm thanks. Yeah, I’ll uh, I’ll do that.” Alexa pushed up her glasses again, hurrying off in a bit of a huff.

‘Mary’ laughed as she watched the hapless girl rush away. She’d taken the bait hook, line, and sinker. ‘Catherine of Bordeaux’ never failed her, did she? Best cover she’d ever had. Lilith was quite in tune with the desires of bookish young women. They were often the easiest to tempt. All it took was a bit of enhancement to her host body and some bullshit story, and Alexa was more than ready to drink whatever she’d put down on the bench. It was a pity she hadn’t taken up Lilith’s offer to spend some time together, though. That would’ve sped up the pressure cooker a bit, and right in front of the succubus’s eyes to boot. Ah, well. She’d be hearing from Alexa soon enough.

Lilith looked down to her thicker curves. Mary DID look much nicer with these enhancements. Perhaps she’d enjoy them while Alexa was occupied. Perhaps she could find a man to entertain herself?

Alexa slammed the door shut to her apartment. She still couldn’t believe what had just happened. Mary? Coming onto her like that? She’d never seen that kind of behavior before.

“Maybe I should’ve taken her up on it.” A voice in her head thought. Alexa shook it aside. She wasn’t the type to be so spontaneous. That was a hell of a body, though…

The girl set her keys down on the countertop nearby, walking back into her apartment. It was decorated mostly with old things: old maps, old posters, old books full of old information. She had a passion for it, which is why in their little group—imaginatively titled the Demon Killers by Trent—she was the researcher.

Yet another reason why this Catherine of Bordeaux shit surprised her. She didn’t know Mary to be the type to go into dusty tomes.

“Must be more to Mary than meets the eye.” The voice answered.

Sitting down at the desk in her room, Alexa decided to ignore the heat remaining in her belly and started to idly flip through the book she had most recently been reading. It was regarding incubi, the male equivalent of the succubus. While the succubus preyed—and fed—mainly on males, the incubus targeted women. Though she’d joined the Demon Killers to hunt demons, they’d made frustratingly little progress. It seemed like there weren’t many demons around for them to hunt.

The page turned to a diagram. It looked a lot like the Incubus version of the Vitruvian Man, limbs splayed out in all directions. Alexa regarded the curved horns and eyes of thing on the yellowed page, conniving and devious. Then she found her gaze traveling downward, down its chest, towards the… other limb.

The cock on the page was remarkably well-drawn. She could even make out its veins. She could feel the heat expand in her loins at the sight of it.

“Just imagine that thing inside of you.” The voice thought. Alexa’s suddenly noticed that her hand had found its way to the button of the jeans she was wearing, hovering just over her crotch.

“What am I doing?” She thought aloud, moving to withdraw her hand. But instead it stayed there. So did her eyes, fixated on the incubus cock. Was she really doing this?

“It’s just a picture.” The voice thought. “What’s the harm?”

Inhibitions finally gave way. Alexa pushed her fingers further down, bringing them to her much-neglected pussy. She began to masturbate, forbidden thoughts she’d pushed aside long ago returning to the forefront of her mind. She imagined the incubus, his cock huge and throbbing, jackhammering into her. As Alexa fingered herself, she imagined herself in a ****’s raggedy outfit, on all fours, crying out like a slut as it pounded her. The sheer taboo of it drove her onward as she fingerfucked herself, right at her own desk, right in front of this book. Alexa the whore, Alexa the cockslave. Was that what she could be?

Alexa came then, the orgasm washing over her like a wave. From her pussy, powerful electricity raced through her body as she let out pleasured whimpers. Though she didn’t realize it, the other voice in her head seemed to giggle within. She kept going, rubbing away at her pussy until it finally abated.

“Holy shit!” She breathed, the reality of the situation finally hitting her. She really just masturbated to a picture of a demon, didn’t she? A part of her felt disgusted at what she’d just done, but there was no doubt she felt very, VERY satisfied by it. She closed the book, lest the incubus image drive her to lust again.

“I could go for another round. I’m really horny.” The voice said. Alexa did her best to ignore it.

Alexa stood back up again, tugging a little at her bra; suddenly it’d felt uncomfortably tight. Immediately though, her eyes caught her reflection in the mirror. What faced her was not the same woman as before. Her breasts and ass had undoubtably grown in size, nearly busting out of her shirt and pants. She quickly took them off, shocked at the sudden growth of her body’s curves.

“Holy shit!” She exclaimed again as she unhooked her tightly-bound bra. Her breasts spilled out, no doubt a cup size bigger than earlier. “It… it really worked!”

“You’re so hot.” The voice returned. “You should enjoy your new body, slut.”

“Wait…” Alexa muttered. ‘You’re’? That wasn’t how she normally thought. She looked back to her reflection and caught her hand sneaking down under her panties again.

“What the fuck?” She exclaimed, pulling her hand back. She DEFINITELY didn’t mean to do that again, not consciously anyway. Was this because of the potion? The heat in her loins wasn’t dying away. If anything it was increasing, especially with the sight of her own hot body in the mirror.

“You should really cum again.” The voice said. “It would feel sooooo good.” Alexa wasn’t sure she could disagree; her inhibitions were slowly melting away like hot wax. Involuntarily—well, almost involuntarily—she let her hands wander again, sliding her now soaked panties down her newly improved legs. She went to work again, no longer feeling in total control of her own body as she masturbated again in front of her own reflection.

Alexa’s hand cupped her new breast. She jerked off with the other. “You are so hot.” The voice repeated. “You are such a slut.”

“What the fuck is happening?” Alexa whispered, realizing now the voice in her head was not her voice at all. Masturbating in front of the mirror? This wasn’t her.

“Don’t question it.” The voice said more loudly. “You just need to cum again, slut. Cum again, whore.” Alexa kept fucking herself, her slick pussy being ravaged at her own hand.

“This isn’t… something’s wrong…” Alexa felt her senses begin to dull. Her vision was beginning to darken as her pussy burned with pleasure. She wanted to cum. She NEEDED to cum.

“Cum, you mortal slut!” The voice commanded. “Cum and give me your body! Cum and give yourself over to me!”

Everything went black just as Alexa came hard. So hard, that her soul left her body. The pitiful moans she gave as she lost consciousness were quickly replaced by louder, hornier, deeper, sultrier moans as control of her body was finally, totally lost. Her fingers kept masturbating though, riding her orgasm out to its grand conclusion.

The look on Alexa’s face had changed from confused to satisfied, the eyes behind her glasses bearing an entirely different expression. She caught her breath, standing straight up to admire herself again in the mirror.

“A bookworm’s body, huh?” ‘Alexa’ said in a voice that wasn’t hers, tussling her hair a little. She brought her pussy-juice-coated fingers up to her mouth, savoring the taste of girl cum. “She could be worse, I guess…” She decided.

The nude girl sauntered over to her discarded clothes, rummaging through her pants until she found her phone. “How do these new things work…” She muttered. Eventually she muddled through it, bringing up her contacts and putting a call through.

The other line picked up. “Oh, hey Alexa!” Mary’s voice ringed out cheerily. “Changed your mind about coming over to my place?”

“It’s Shara, you frigid bitch.” Alexa hissed in her true succubus voice. “Your little possession potion scheme worked.”

“I see.” Lilith responded. “How was she?”

“You like this body snatching stuff more than me.” Shara said, looking back over to the mirror and sticking out her round ass. “But she was pretty easy to take.”

“I’m glad you agreed to come up for my little vacation.” Lilith said. “But it’s a working vacation, really. We have some hunters to take down.”

“Whatever.” ‘Alexa’ said, taking off her glasses. “You can tell me about it after you fuck me. I’m not lifting this girl’s finger until I get some lesbian action.”

Lilith chuckled. “I figured that would be your response. I'm outside.”
