Luz had watched from behind the bushes as the two witch students bickered. It seemed like such a classic set up, the kind she'd read and indeed fantasied about many times. She'd swoop in and help the little witch girl prove herself to the bully, and they'd become the best of friends forevermore!

She'd just been speculating over what manner of heroic underdog her new potential friend was when the ground had erupted with vines, a magical green aura engulfing Willow as she let out the frustrated shout she'd suppressed during the encounter with Amity.

"U-um, hi?" Luz greeted sheepishly, wondering if stepping into view at that moment had been a bad thing.

Unfortunately, Willow's magical frenzy wasn't quelled by Luz's pleasant greeting. Luz didn't realize until she looked into the witch girl's glowing green eyes that while the lights were on, no one was home; or if they were they were tied up in the basement. However you'd phrase it, the sweet girl Luz had been about to greet was no longer the one in control.

Luz recalled Eda mentioning in passing how sometimes powerful witches had their magic and emotions blend together. She'd spoken of it in reference to a spell becoming stronger, but evidently the spell could also take over if the magic was that much stronger than the body could keep up with.

Luz backed away slowly, but it was too little too late, and she was being lifted off the ground by a nest of thick, writhing vines before she could escape. Thinner, thorn covered vines shot out from them, shredding Luz clothes before binding her body.

Luz winced at the feeling of the thorns against her skin, only to realize they'd vanished. Luz couldn't tell if it was a sign of her precise control, or a sign of her lack of control over anything she wasn't directly focused on; like repurposing Luz's mouth, which seemed to be first on the list.

Luz's body was pulled down by the vines as Willow stepped out of her clothing, vines holding onto them like closet hangers as she mounted Luz's face.

Normally she'd be offended at being used for someone's pleasure without being asked. But she doubted the girl was even feeling it conscious; and probably really needed the release if she was tense enough to lose control like this in the first place.

This in mind, Luz pushed her tongue out, digging into Willow's slit with more willing eagerness than Willow's current state would have expected.

She moaned happily at the pleasure, legs squeezing around Luz's head as her vines did the opposite, relaxing around the human's body to make her more comfortable as her tongue worked deeper inside.

'She tastes so sweet, like a honeysuckle.' Luz realized as she worked, digging in deeper for more of her tasty juices.

Willowed groaned, getting wetter against Luz's face as she got closer. She could feel herself getting closer, but she didn't want to be done yet.

She wanted to be angry longer, wanted to be wild and on the loose longer. And as her vines felt Luz's cock throbbing against them, twitching in the flora bindings, she found the perfect way to.

Willow pulled off of Luz's face, Luz pouting in disappointment as she did so; at least until the vines lifted her up and exposed her cock. It sprang to attention, more than ready to be used.

But Willow, or at least this semi-feral, magically conscious side of her, didn't care if she was already ready. Luz squeaked in surprise as some kind of pollen burst from flowers that spouted on the vines. She coughed as she inhaled it, unable not to despite trying.

She had a reasonable guess what it was from context alone, but the painful throbbing in her member confirmed that whatever was in these flowers was meant to keep her going even after she wore out. Willow mounted the futanari human, pressing her slit against Luz's tip.

Luz squirmed, whimpering as she squirmed in the vines. Willow didn't take her inside, not right away. She just rocked her hips, teasing herself with the human's cock like she was a simple toy, causing her pollen spiked and-unknown to her-potion spiked cock throbbed with need.

Willow slowly started taking Luz inside, moaning hard as she felt it stretching her tight hole. Luz moaned hard, happily for the tight warmth around her rod but still feeling unsatisfied with the need for more.

Unable to thrust, she was trapped at Willow's slow pace, meant to only satisfy herself. As Luz bit her lip so hard she worried it would draw blood, Luz hoped that she was right and this cute witch girl was only this aggressive when wound up like this, otherwise she may have made a subpar choice in demon realm friends yet again.

Thankfully, though it took a bit of time, her fears on this were quelled. Luz had actually zoned out a bit, the desperate itching need to cum and constant denial melting her brain to mush. She only recovered from it when she finally came.

She moaned, hands moving to Willow's hips. With a start she realized the vines had receded, letting her squeeze Willow's soft, smooth body as her member spurted over Willow's ass.

"Mm~" Luz purred, alerting Willow that she'd come to.

"O-oh hey! I'm so sorry about before, I didn't mean to do any of that!" Willow explained, continuing to massage Luz's swollen stiffness with her plump, soft ass to work more of the desperately pent up cum from her. Luz could tell from her tone that she was being genuine, and simply moaned from the pleasure.

"Just relax, I'll work all that pollen out of you. I can't believe I used that stuff."

Luz tried to tell her that there was no need, wanting to ask her about her magical school woes. But that conversation would have to wait, as all her attempts faded into moans as she thrust against Willow's soft body gently.

Whatever was in those flowers, it was reacting with the potion fueling Luz's normal lust. Willow and Luz would have plenty of time to get to know one another and formulate the first of many terrible plans doomed to backfire amusingly while Willow tended to Luz's throbbing, turgid stiffness.

It would not be the last time Willow spent an afternoon assisting Luz with an erection she'd caused, though it was certainly the most intentionally caused.
