Kaltxi nodded. Seni had been expecting a sly smile, or a giggle, or some other indication of 'victory' on the Affini's face, but instead, they were met with a sincerity they had never seen in him before. "Okay, petal. If that's your wish, I'll be very happy to fulfill it. But first, I need you to promise that you will trust me."

It was like autopilot had taken control of Seni's body in their anxious state. "I promise, my Master," they said, without even realising it.

Kaltxi lifted up the device they had taken from their table and showed it to Seni. "This machine will apply your drugs. They will make you much calmer, and much more sensitive. As far as I know, you have only experienced passively secreted xenodrugs, so this will be much stronger than anything you've felt so far." The machine was a small box, with a few slots, two of which were already filled with vials full of strange-coloured substances. On its surface, it had an abundance of all sorts of knobs, switches and buttons, far more than Seni was able to quickly figure out the purpose of. Out of the box stuck out a tube leading to what looked like a face mask.

"I believe you will be most comfortable with inhalation. The other methods of applying the drugs are a bit too physical, and I don't want to scare you. Put this on your face now, please." He handed the tube to Seni, and they obeyed. "Now, if you need to stop, just tell me, and I'll give you the antidote right away. Do you understand, little Seni?"

Seni nodded. "Yes, my Master." They lay down, closed their eyes, and put the mask snugly around their mouth and nose. Kaltxi put his hand on Seni's, helping them to hold it appropriately tight.

"I love you so much, my little Seni. You're being so brave for me."

Seni heard a whirring noise and, within less than a second, their mind was gone. Suddenly, their bed became infinitely comfortable; it was like they're sinking into it, drowning in it. They felt like they were floating on a cloud, and their muscles so relaxed that Seni was hardly able to move even their fingertips. Their vision was so blurry, they struggled to make out details of Kaltxi's face, which was smiling down at them. To top it off, their skin became extremely sensitive, so much so that just feeling his hand on their own felt like the greatest pleasure they'd ever experienced. Slowly, Kaltxi took the inhaler’s mask off of Seni’s face and put the machine away on the floor.

"I can tell it's kicking in already! Are you comfortable?"

Seni did not understand a word he said. Their face was locked in a mindless smile and their hand began shaking, desperate to feel Kaltxi's touch again. He quickly fulfilled their wish, picking Seni up and spreading apart the vines that formed his arms, enveloping the little human in them. The sensation of the vines slithering over them was powerful enough just by itself that Seni began to moan in pleasure.

The vines began stroking all over Seni's body, feeling them up, trying to push all their buttons. They moved around, discovering what movements enticed the best reactions from them, and which places were their favourite to be touched in. To Kaltxi’s surprise, no matter where he touched them, Seni always reacted in an undeniably positive way, though some places appeared to feel much better than others. It didn't take him long to figure out which parts of Seni were the most sensitive, and thus he decided to stop holding back and go all out, making sure to focus especially on those parts. After only a few minutes, their neck, their chest and their crotch were almost completely covered in vines, making them feel so incredibly good.

Seni could not think anymore. In this moment, all their mind was able to focus on was their own intense pleasure. They had never felt anything like this before, they had never felt anything even close to this. The sensation was beginning to cause Seni to convulse strongly, as they experienced strokes of orgasm all over their body, again and again, endlessly. Their moans turned into frenzied screams. Kaltxi gradually slowed his movements to a halt and spoke to Seni, very slowly, yet sternly, trying to make sure they understood him through their drug-induced haze.

"Seni! Petal! Are. You. Okay?"

Seni finally managed to catch a much needed break. Every part of their body was still shaking, and their breaths were deep and irregular. Their eyes were wide open and filled with tears, staring directly at at Kaltxi with a crazed expression. Seni began to mumble between their breaths, with immense joy and passion in their voice: "My Mashter!... ah... My Mashter!... Moahr!... Moahr!... ah... Pwease! Moahr!"

Kaltxi couldn't help but laugh. "And here I thought you'd already had enough! You'll get more if you want, you greedy little sophont!'

He lifted Seni up, bringing them closer to his chest. More of the vines that constituted his body unfolded and began to move all over the human with even greater passion. Kaltxi toyed with each of the different parts of their body, fluctuating the speed and direction of his movements, as if trying to find every possible combination of ways and places in which he could touch the human. Seni was practically writing in pleasure, being squeezed and fondled in all sorts of ways they had never imagined, yet Kaltxi remained careful not to hurt them, feeling out their body, testing its limits, exploring its every nook and cranny. Everywhere the vines could reach, they explored, and every new spot they touched filled Seni's mind with overwhelming orgasmic sensation that completely took over their mind and sent their heart beating into overdrive. It wasn't long until the vines had finally made their home on and around every last part of Seni, making them squirm and convulse with the entirety of what little strength their muscles still had in them.

Seni was no longer even able to express the sheer pleasure they were experiencing. Their eyes were tearing up, drool was dripping from their open mouth, and they were making noises Kaltxi hadn't even known humans were capable of. Their entire body was covered in sweat and waves of liquid were pouring down their legs. Every part of their body, down to the millimetre, was covered in vines and leaves, and every last one of them was sending waves of intense orgasm to their brain, one after another, and all at the same time, amplified hundreds of times by the load of drugs they were on. If Seni were able to think, they would likely be in utter shame of how undignified they were looking now, a big, slobbering, squirming mess that hardly resembled a person.

But Seni could not think, not about anything but pleasure. None of their life's worries were real anymore. In that moment, their whole world was contained within their body, the vines covering it, and the immense, unfathomably massive loads of orgasmic sensation they were delivering to them through their skin. They were trapped so deep in their vortex of enjoyment that they had lost track of their own needs, the extreme levels of pleasure taking a serious toll on their body. Their breathing became shaky and erratic, as if they were forgetting their most basic instinct, and their muscles had become extremely tired. Finally, it felt like they were beginning to have had enough. The intense good feeling was slowly being replaced by an unpleasant and almost painful tingling, as if their own nervous system had numbed down from overexertion.

Seni's movements slowed down, their body apparently giving in. The smile on their face gradually faded into a look that resembled a desperate frown. A river of tears rolled down their face and their screams of pleasure began sounding more like pained cries. Kaltxi quickly caught on to what was happening. Retracting his vines and composing himself back to a humanoid shape, he gently put Seni down and let go of their body.

"Little Seni, my darling petal, are you alright!?" He screamed, his voice filled with panic.

Seni quieted down, breathing deeply yet hastily. They tried to say something, but their mind was still blank.

"Mu... mu Mushtah... thunk... thunk yoo..."

Kaltxi let out a small sigh of relief. It appeared he reacted right on time, and Seni was fine, though overwhelmed. He smiled down at them, watching, careful not to touch them. It took a minute or two, but their breathing finally steadied.

Seni still found it very difficult to think. Their bed once again felt impossibly comfortable, and they became overwhelmed with exhaustion, sinking deeper and deeper into it, their mind practically empty, until finally, they drifted off to sleep.

As soon as Seni awoke, they opened their eyes and jolted up. What time was it? Seni felt like they had been sleeping for years.

Kaltxi was sitting right next to them. "Careful, petal! Please don't move too much, you must still be so tired."

Seni immediately realised it was true. It was like they suddenly regained feeling in their body, and they regretted it. Every part of them was sore, and they were so exhausted they could barely move.

"You need to drink. You lost a lot of fluid." The Affini handed Seni a big bottle of water, but they were too tired to lift it up, so they helped their hand up to their mouth. Seni drank all of it in one go.

Once they finished, Seni eased up all their muscles and fell weak again. Kaltxi put down a pillow to help them remain in a sitting position.

"How do you feel, little Seni? Are you able to talk?"

"I feel... so tired..." Seni responded, mumbling. Despite the tiredness, their mouth formed a slight smile. "That was... Wow... That was so..."

Kaltxi smiled back. "Did you enjoy yourself?"

"It felt... It felt so much better... It felt a million times better than... than I thought it was even... even possible to feel!"

Kaltxi giggled in response, but then quickly turned serious again. "I'm glad you liked it, but I'm also sorry, little Seni. I must have underestimated how strongly the drug would affect you."

Seni simply continued to stare off absent-mindedly with a smile, their mind seemingly just as exhausted as their body.

"I gave you a healthy dose of antidote to wake you up, so I could give you water. But you really need to sleep some more now."

Seni leaned back. "Yes... my Master..."

Kaltxi took the pillow out from under Seni's back and tucked them in with a heavy blanket.

"Little Seni, my dear?"

"Mh?" they mumbled, already half asleep.

"Thank you. For trusting me."

Seni smiled widely as they drifted off.
