Desert Knight just can't keep himself out of trouble when Nightshade is involved. He's luck that his arch-nemesis only wants to toy with him, or his fate could be so much worse!

Freshly milked of his cum for the sake of harvesting his DNA, the defeated coyote wakes up to a series of vines and tentacles keeping him bound, while Nightshade poisons his mind with hypnotizing serums. Better judgment falls to naturally inflated lust, and in the heat of the moment, Nightshade decides to take another sample of his seed, for personal enjoyment.

Calling Nightshade a sociopath was a grave underestimation, and it didn't give nearly enough credence to the fact that she was an incredibly dangerous person.

She knew that her captive was starting to sober up, and one of her ears flickered as she heard a low, pained groan, barely escaping the confines of his lips.

"Y...You...bitch..."

"A female canine is often referred to as such, yes."

Her ability to change mood and tone on a dime was every bit as impressive as her mastery of horticulture, and in the short amount of time that Desert Knight had been on his knees, coming out of a nearly comatose state, she'd already taken the beaker of his cum and separated some of the samples, pouring the slick and runny fluid into a number of different test tubes.

"You really have n-no idea what you're getting into," the coyote warned her, still believing that she didn't have a full grasp of just how dangerous his DNA could be, if it fell into the wrong hands. "If your concentration slips up for even an instant, you could have an army of invulnerable flora running rampant through the streets!"

"Reclaiming the world that was theirs to begin with? That doesn't sound like such a bad thing, really. I was just thinking that a few of our metro areas could use a fresh splash of green color."

Whatever part of her mind contained the deadly, murderous aspect was taking a quick break, and her words were very short and matter-of-fact as she sat at her desk, taking notes and acting as if she didn't still have the flavor of the coyote's manhood on her tongue. How she could be so nonchalant after the battle they had, not to mention the twistedly erotic interlude that followed, was beyond Desert Knight's ability to explain.

Even if he wasn't still fighting through the toxins of the plants that held him in bondage, he was sure that he'd have quite the difficult time figuring it all out.

"And you're so sure that you can control them? What if they decide to turn on you, completely indestructible and able to regenerate at the drop of a hat?!"

The lack of protest from the coyote while he was sleeping on his knees put Nightshade back into a docile mood, but his fiery passion stoked something similar in her own loins, and she grinned for a moment as she set her pencil down upon her notebook. She stood up out of her chair, stuck her rump out with a full, firm pop of her hips, and stretched over the table, pressing her breasts down into the small mountain of research that was laying before her.

"After all that I've done to show you how obedient my little lovelies are, you still doubt my ability to control them?" she asked. Without bothering to wait for a response, she began peeling back further at the tight, gripping fabric of her already tussled costume, and her hips began to sway as the fabric struggled to peel down from the wide, luscious curve of her rump. "Sounds to me like you need another display of what they can really do, my little coyote."

Once again, her mind was turning on a dime, and Desert Knight could feel his body lifting from the ground without so much as a gesture from the villainous Doberman. The vines that kept him in bondage as he slept never loosened upon his flesh, and though his mind was sobered up, his body was still weakened by the toxins that had coursed through his veins.

He could hardly wiggle against the vines as they carried him through the still, quiet air of the greenhouse, and as if to taunt him with the possibility of what was to come, his footpaws were allowed to hit the dirt.

The vines forced him to simulate a walking cycle, and all the while, Nightshade looked back over her shoulder at him with narrowed, glowing eyes, as if she was waiting for her private lover to come and satisfy her.

"This is sick, Nightshade. You can't possibly think such a simple and disgusting display is going to convince me that you're to be trusted with such dangerous weapons!"

"Oh...it's sick , you say?"

Her lips curled into a wide, terrible grin, and the vines clenched fiercely tight around the trapped coyote, causing a horrid sense of discomfort to spread through his limbs. "Here's a fun little fact for you, Desert Knight: I don't really give a damn what you think is or isn't sick, and the only reason you're still alive is because I wanted to fuck your brains out after I got done sampling your seed...so how about you stop doubting my ability to control the plants, before I make them choke the life out of you?!"

He didn't want to gulp. In the utter silence that followed the terrifying statement, Desert Knight knew that it would be the only sound, and it would be music to her ears.

He couldn't help it, and his throat turned dry as the desert as she giggled in reply.

"Y-you...you wouldn't do t-"

"Boy; I'd choke the life out of you and fuck your soul on the way up to the heavens."

Such a grievous statement was one that he couldn't easily abide, but the coyote didn't have much of a choice as the vines skipped the slow, casual walk and thrust his body right up to her backside. Toxins seeped into his fur anew, and though he was allowed to keep his right of mind, he couldn't ignore the sudden and painful throbbing between his legs, as the toxins forced his cock to grow stiff against the inside of her thigh. Precum began spitting at her costume almost instantly, and his orbs shifted in his sack unnaturally fast, leaving him to wince into her ear as the vines pinned him down to her back, and left his chin upon her shoulder.

"I guess what I'm trying to say is...be grateful that you're still alive, little lab rat. I've got a new experiment for you."

Though she took a deep pleasure in soaking her tongue with the first load of cum, Nightshade could admit to herself that there was a greater purpose behind doing so, and the experiments his yield would allow her to conduct would likely advance her devilish schemes to new, threatening heights.

This second, blissful round was just for the fun of it, and just to taunt him for his bonded state, Nightshade bucked her hips back against the pulsing, quivering length of the defeated hero and rubbed the smooth, delicate fur of her inner thigh against his shaft, leaving him to tremble with a pleasure that his mind tried to resist, but his body easily gave in to.

"I w-won't...I won't let you get away with this, Nightshade," Desert Knight was panting, his eyes winced with forbidden delight. "I'll find a way to stop y-

Nightshade rolled her eyes and reached back between her legs, squeezing the tip of her forced lover's cock. "Drop the hero act and fuck me already, kid. You ain't going anywhere , or stopping anything until I get off."

Knowing exactly what she wanted and lacking the patience to wait for it made Nightshade that much deadlier in a passionate moment, and though he didn't have the strength or will to resist the influence of the lively vines, Desert Knight never would have guessed how close he came to actually meeting his maker, that evening.

The very plants that he sought to destroy saved him as they heavily bound his hips. His body nearly disappeared under the mass of vibrant, green tendrils, and the weight of the throbbing vines pushed down on his backside, forcing his toxin-riddled body to cooperate.

"You...c-can't...do this!"

"Can," Nightshade claimed, as she felt the plants helping to guide the defeated hero into her folds, "And I am...the least you could do is be grateful for getting to fuck such a tight, sweet flower."

Blurring the lines between plants and animals so effectively was just another one of Nightshade's forbidden talents, and there was no doubt in the coyote's mind that she'd done all manner of lewd and sinister things with the tentacles, when she wasn't using them to help with her dirty work.

He blamed the toxins for the simply raunchy train of thought that followed, as he tried to fathom just what ways a sensual canine would use vines for, if they knew that there were no risks involved.

"It's not th-that tight, y'know."

Such blind and foolish arrogance would have been enough to get a lesser man killed, and Nightshade knew that her toxins could do the trick, if she really wanted them to.

Instead, she licked her lips and allowed her fangs to shimmer at him, showing off just how much she enjoyed his rebellious spirit. "Go on, you noble hero. Keep pretending you don't love the feel of my pussy squeezing the life out of your cock...act like this isn't the reason you came here in the first place!"

A renewed vigor forced Desert Knight to try and writhe against the vines once more, but they held firm against him. A strange sound like the laughter of childish ghosts began to fill the air around him, and his ears perked up to find the source, but his eyes were stuck looking straight ahead; a tight vine was wrapped around his neck like a slave's collar, forcing him to gaze down at Nightshade and lock eyes with her as she began rocking her hips against his thighs.

"You know d-damn well I didn't come here for that!" Desert Knight managed to protest through his moans, but his length was pulsing with harsh and sincere purpose, and even without the grasp of the vines, he wasn't sure that he could have resisted plunging his length into her sex any longer.

Nightshade was loosening the grip of the vines little by little, allowing the coyote's hips to continue the pace of their own volition. She noticed how much deeper he was reaching on each pass, and once more, she giggled to herself, refusing to reveal to the defeated hero that his actions were just as much his own fault as they were the influence of the toxins. "You didn't? But I defeated you so easily! I'm sure you meant to lose," the Doberman claimed, and as she did, she reached back through her own thighs and rubbed at her tiny, buzzing clit with a pair of eager pawtips.

Vines slid up along the surface of the table and wrapped around her bare breasts, squeezing the already perky flesh and forcing it to deal with a playful and delightful tickle, and though he didn't need any extra incentive to reach a second climax, the tiniest, smoothest tendrils came to settle upon his sack, spreading out like delicate webs of sensual electricity.

"You g-got lucky!" he decried her theory, but even as he did, he could feel the familiar bubbling in the pit of his crotch that revealed a rush of his seed, and just before he was able to cry out with orgasmic delight, a single vine wrapped multiple loops around his muzzle, keeping his lips perfectly sealed.

A quick bump from her full, round backside was all it took to push Desert Knight to the ground, leaving him on his tender backside, and with a teasing wiggle of her hips, Nightshade lowered herself onto the glistening, messy length of her capture and began bucking wildly at his flesh, having saved the very best for last.

"You're f-fucking right I did," she agreed, her face brazen and grinning with sadistic pleasure. She knew that she was literally stealing the cum from the hero's orbs, and as she felt that delicious, organic warmth pumping into her womb, she slammed her rump down in his lap with such force that it nearly took the wind out of him. "I found a man who can actually k-keep up with my needs," she explained, speaking right through the throes of her climax as if her inner walls weren't fluttering and clenching wildly at his throbbing flesh, "And he's giving me another sample! Such a g-good little coyote..."

Her breasts were heaving within the grasp of the vines that squeezed them, and her nipples grew erect under tiny, eager lips that formed in the velvety flesh of the tendrils. She was panting desperately and driving her body down onto Desert Knight with all of the lustful passion she had, and when her own body was finally left a tired, shaking mess, she looked down between her knees to see a small puddle of spilled, creamy essence, soaking into the dirt and leaving behind a part of the hero for her loyal plants to feed on.

It brought a haunting, giggling smile to her face as she looked back over her shoulder, her eyes still glowing with the same eerie aura that made her such an intimidating, yet beautiful woman to gaze upon. "I know you're wild about me, coyote, and it'll be hard for you to stay away...but keep your distance for a bit, all right? You don't wanna risk smothering me with affection...plants tend to die under such duress."

Nightshade regretfully pried herself from the wonderful manhood that had pounded her depths and watched with a tiny chuckle as drizzling stands of his leftover seed spilled back down into his lap. The exhausted Desert Knight was going to force a protest, but before he could, his eyelids became heavy, and his breathing slowed to a dangerous pace.

"Dream a little dream of me, Desert Knight. Only the sweetest ones will come true."

A merciful end to his treatment to be sure, Nightshade merely lulled the poor coyote into a deep and completely relaxing sleep. The last thing he saw was the pouted, dripping folds of the woman he'd sworn to destroy, and he blamed the memory for sticking with him, and leaving him with a terrible case of morning wood when the police came to free him, yet again.
