It was a night of late fall. The air outside was chilly and rather unwelcoming, only suitable for those who wanted to brave it for their own reasons. Such was the case for the pair of women hidden away amidst the darkness of the park. One was pinning the other against an oak that was off the path.

"P-please..."

The pinned one, the prey, was pleading weakly as her smaller frame shifted meekly against the bark. She was unable to break free from her assailant's grasp. Or perhaps, as Vilenia herself had concluded, unwilling to do so. The woman's disposition was betrayed by her body, her words and struggles paling in comparison with the rush of blood that made her blush. Her heart was on fire, among other things.

Vilenia loved the struggles of her prey, but she had a soft spot for this kind as well. The ones that yearned for danger as long as it wore the form that they desired. They were ever so common nowadays. Vilenia leaned closer, close enough that the girl could feel the whispers brush against her ear.

"Please what?"

"Please... more..."

A typical virgin. Vilenia was happy to give the girl what she craved for. She leaned lower, her hair brushing against the human's neck as she bared her fangs and went for the bite. The human's eyes started turning up and her knees buckled as Vilenia took a looooong nice--

Ngh!

The human fell on her knees as Vilenia suddenly jumped back, leaving her slumped against the tree. Something was wrong. Vilenia didn't understand what was happening, or how, but there was something wrong with this blood. It burned. It burned like... like...

"Gotcha~"

Half-conscious, still ravaged by the ecstatic feeling of the bite and the bloodloss, the human addressed the vampire with a droopy smile on her face. She was recovering, starting to lift herself off the ground as she watched her assailant writhe in pain, never breaking eye contact.

"Do you liiike it?"

Vilenia couldn't get the words out as the pain seared through her body. It was enough to bend over. It felt like her insides were melting, which might have been true, but the blood sustained her. Except the blood that her body was so greedily taking into itself every passing moment was also the cause...

She managed to raise her gaze to face the human. And she had to *keep* raising it. That was the moment when her anger turned into something more primal. The human was starting to slowly tower over her own form. And the human was loving it.

"How about another? On the house."

Vilenia clawed at the mocking human, but it was easily thwarted. She was in too much pain, wasn't thinking straight, couldn't act right. Even her own clothes were hindering her, shifting against her reducing form. The human could easily overpower her in this state, which is exactly what she did, pushing Vilenia onto the ground. Her arms were locked down by the former prey's knees. It was enforced by a weight that only kept increasing as this insane situation went on.

"What's the matter? You could probably knock me out if you bit me again."

The vampire couldn't understand what was happening. It wasn't just the pain; this woman was a freak. She was actively trying to push her thickening finger past Vilenia's clenched teeth to help the vampire act out on her suggestion. And Vilenia wanted to. She really wanted to, but she still understood through her pain and bloodlust that doing so would be a very bad idea. She simply kept growling through her teeth as her body continued to burn within.

"Well... suit yourself, then."

Sounding disappointed, the human reached out into her jacket to pull out a spray bottle. She sprayed Vilenia all over with a substance that the vampire could smell before it even hit her face. It was more blood. More of her accursed blood. It was burning and its smell was overpowering. It drew out her instincts, her tongue going for licks before being immediately driven off by the stinging. Vilenia was being driven out of her mind.

Everything, all of it, became ultimately too much for her.

Vilenia's mind went dark.

A weak light illuminated the now-familiar motel room. Rommi sighed as closed the door behind her and kicked off her shoes. She really wished that the Order could afford to spare more money for professionals like herself, but it couldn't be helped. The whole operation was the most lethal and thankless charity in the world.

"I guess the bonuses are worth it..."

Rommi rubbed her neck. She had managed to treat herself as far as first aid went, but it still stung like hell. The euphoria of the bite was sadly short-lived. Rommi sometimes did grumble about how vampires were the worst for almost ruining masturbation for her, but not today. Today's fun wasn't over yet.

The brunette smiled. She stripped down to her tanktop as she got ready for the next act. The only other accessories that she took with her to bed were her glasses, one lens of which had a magnifying addition, and a matchbox that she dug out of her coat's pocket. Something was jostling inside of it, but it wasn't matches. Rommi only hoped that that something hadn't accidentally harmed the matchbox's more important passenger. It would have been most unfortunate.

She slid the top open and peered inside. The tiny vampire had been clawing at one of bottom corners in a vain attempt to dig herself out. It was all interrupted by Rommi's actions. Her colossal eye hovered over the bloodsucker's container. She seemed scared. It made the human wonder whether the vampire had even realized just how small they had become before now.

"There you are. Enjoy your little nap?"

Rommi licked one of her fingers and invaded her prey's quarters. She tried to stay in the confines of the corner to avoid it, but it was no use. One dexterous swipe was all it took to take her for a ride. Seeing and feeling the creature on her finger like this made it easier for Rommi to estimate her current size. It couldn't have been more than one millimeter at best. This bloodsucker had become nothing more than a tick, if that.

The tick ran, or tried to anyway. She was too small to make any meaningful headway, but the act itself delighted Rommi. Vampires were prideful creatures. They only even considered running away if they faced something that was a threat to their existence. At this very moment, that threat was Rommi's very own existence.

Rommi brushed her index finger with her thumb as lightly as she could manage. Focusing with her magnifying lens revealed that the vampire had taken quite a beating from being dragged what felt like a very small distance. She was still very lively. Her intense expression and mouth movements indicated that she was trying to scream something at Rommi. It was impossible for the human to hear any of it unless she'd bring her right against her ear, but she had no interest in doing so. There was no conversation to be had.

"You're lucky. Others might have killed you by now, but I'm not that cruel," Rommi said as she took the lancet out of the matchbox.

"I know what you really want."

The needle descended, planting itself at a safe distance half a centimeter away from the vampire. There was no blood, not yet. The puncture was too small to make it spill forth on its own, but the creature must have already smelled it. Rommi could see it in her expression, in her peeking fangs, in the way that her body started to tremble. It was adorable. It also got Rommi's own desires going, but she had to wait. The next part was very delicate.

"You were too horny for blood to smell it, but by now you know fully well what my blood does to you."

Rommi's other hand carefully wrapped two of its fingers around the sides of the one that the vampire vacated. She squeezed. The ground beneath the vampire shifted and her worst fear was finally realized. A small droplet of blood had revealed itself from the minute puncture. It was small, but it was still almost the same size as the minute vampire, if not more.

"But you lot are parasites. You don't drink to live."

Another squeeze. The droplet doubled in size. It had eclipsed the vampire and in doing so continued to creep closer to her through sheer expansion. But the vampire wasn't moving. It no longer tried to run away. All it could do was stare at the growing intoxicating mass grew bigger in front of its eyes.

"You live to drink."

One more squeeze doubled the droplet once more. It got ever so close to engulfing the bloodsucker entirely, but to Rommi's relief it didn't do so. It was painfully hard to avoid engulfing her whole existence, both physically and mentally, but Rommi didn't allow herself to. Her assisting hand retreated to assist in other ways, by teasing her own nipple as she watched the vampire closely.

"So. Drink."

Rommi tried to imagine what it felt like. She tried to imagine what it must have been like, being faced with something so obviously lethal yet intoxicating that you had to partake in it no matter what, but failed. Her own pleasure-seeking was very risky, yes, but she was a professional. She would never forsake her own life for such things, unlike--

"Ah."

The tick had done it. She had jumped in. Rommi bit her lip as she saw her prey diminish at a rapid rate, vanishing into the droplet. She could no longer wait herself. Her hand was plunged deep between her legs. The scenario itself had been enough foreplay, and it and driven her far too close to the edge. It didn't take long until the stimulation of her inner walls let her orgasm, her pussy clenching hungrily at her own fingers and washing them with her juices.

Rommi simply laid there as she caught her breath. She didn't remove her fingers for a few moments, brushing idly against her walls until finally accepting that she was done for now. It was done. The minuscule drop had mixed in with her flowing juices. Whatever was left of the bloodsucker was surely gone by now, either washed away by the cum or stuck to the contracting walls. It would have been the end of her either way.

"Or maybe..."

Rommi brought her fingers back up to inspect them. They were slick with her own juices and didn't retain any signs of anything else. Not that that meant anything.

"Or maybe you're still here?"

Rommi's gaze lingered on her slick fingers, but for only so long. She was quick to suck them clean. All possibilities had to be eliminated. If the Order found out that she had let one of these creatures go, even a microscopic one, there'd be a hell to pay. She'd file the report in tomorrow. 

"Maybe it's a miracle that they pay me at all for this..."
