A celebrity trainer makes a purchase (Sincubus)

When Allison clicked on that ad online, she didn't think much about it. In fact, she had almost forgotten about it when the article she had purchased appeared on her doorstep the next morning.

But there had been something that had pulled her to buy this item from a local sexshop. A strange pull that had completely removed her worries and thoughts and just led her to the clicks until she purchased it.

Now, she didn't know what to think of it.

Allison was in her apartment in Los Angeles right now, where she had set up a small private gym for celebrities that wanted to keep out of prying eyes. She took one look at the mirror in the wall of the room.

She had worked hard to get where she was, to get the stunning body that was reflecting in the mirror, and the wealthy and influential clients that she worked with.

She decided to take the box to the bathroom and open it up there. There was still some time before her first appointment arrived, but she didn't want to accidentally drop the receipt here or something that might embarrass her.

It didn't take much for the vigorous woman to open the package. She took out the small jar and gave it a curious look. It had a deep red color and a black sticker with a lewd image in the background. She couldn't find any brands, or any other indication aside from the description "Clitoral Stimulation Cream"

Allison gave it a curious gaze. She could still barely remember anything about the night before when she had purchased it. She opened the lid, wondering what it looked like, and an overwhelming smell came out of it. It was undeniably the smell of sex but with a pungent sweet scent as well that masked it slightly and gave it a more exotic aroma. The cream was so dark that it looked to be absorbing light from the room.

Allison hadn't intended to test it here, or maybe ever, before she opened it. But that odour had overloaded her senses and she felt almost commanded to try out it right now.

She settled on her toilet and pulled her shorts out, leaving her shaved pussy out in the open. Scooping up a fair amount, she couldn't resist to give it a gentle lick. She didn't know if it was edible, but at this point, she didn't care either. The cream was delicious, and it has a very familiar taste that she couldn't put a finger on.

She placed the rest of the gel above her clit, spreading it around the area. The woman couldn't hold a moan as she felt her loins burning up from the inside, a fierce sexual warmth focused specially on her clit. Throwing any cares out of the window, she began to furiously masturbate, moaning louder than she ever had before.

Because she felt more pleasure than ever, too. She was very sexually active, usually flaunting her athletic body to get any man, and the occasional woman, that she wanted.

But this was something else. Her heart beated like she was running a marathon, rapidly pumping blood to all her body.

Yet nowhere as much as her clit. Allison felt it pulsing of its own accord, having enlarged from a mere nub to the size of a thumb. Yet she kept at it, frenzied, not bothering to ask how or why.

Not even as it kept growing and hardening, reaching 3, then 6 inches, with a slit opening up at the tip. Allison just got her hand across it and pumped.

She had taken so many cocks in her life, the thick members of the muscular men that usually spent day and night in the gym.

But now she wondered, for the first time in her life, what it would be like to have her own. A hard shaft that she could use to fuck her gorgeous clients, and take their arrogance our of their face. There were so many female celebrities that she could use this on, and she imagined herself deep inside of every one of them.

Her new addition was throbbing hard, as her fibrous arm furiously stroked it with no decorum. But even though she imagined it had gone for at least half an hour now, there was no end in sight. Why couldn't she climax?

Give in to me...

She heard a sombre, distant voice in her head. She didn't look for any explanation for it. She knew, instinctively, that the voice could give her what she wanted.

Give into me... Serve me, and I will grant you your release... I will grant you perfection...

Allison didn't hesitate. She had never been bothered by morals or conscience, but lived a completely hedonistic life. Even without saying it, the voice was promising all that and more.

"Yes! Do it! Make me perfect!", she yelled to the air. She came as soon as she finished the sentence.

Long ropes of black cum sprayed out of her cock, showering her in her own fluids. She took her tongue out, desiring to taste it, and found that it had become much longer and serpentine. Her body already made every woman green with envy, yet it still improved in one noticeable way. She was left completely naked when her sports bra snapped when her breasts expanded to ripe, firm E Cups.

Only now they were colored scarlet red, as was the rest of her body save for her hair, which was a shiny black. She especially relished her last changes, the 2 inches growth to her already hard shaft and the appearance of a long tail ending with another cock in the top.

She was picturing how she would use them to stuff the holes of those pretentious celebrities when...

"Hello? Allison?", a female voice came from the hall, as the door closed behind her.

The new Sincubus grinned.

Her prey had arrived.
