Not your problem but actually your problem

You spend the next few minutes deep in thought, ultimately without a conclusion as to what to do with the slime. While you can somewhat predict what they'll become from their diet, what's candy supposed to do?

A turn left. Another right.

You reach the double oak doors of your laboratory, but remain on the spot, looking for something.

Eventually, an unfortunate researcher turns the corner, and you gesture towards her to come to you. There's a small echo to her steps. A sharp, melodic click that makes her smart look all the more pleasing to the eye...

What?...

You wince. Stress must have been getting to you lately because you're beginning to notice things you hadn't paid attention to before.

Have those dark undergarments always been shading through the white robes? Why do some female researchers prefer not to wrap their chests?...

This one, for example. The pointy tips on her breasts **** a furrow to your eyebrows as you keep your eyes from wandering.

"Greetings, headmaster." She nods once, carrying herself with a serious tone. "...Is there something I can assist you with?"

"Greetings." You nod back, noticing the scribbled scrolls under her armpit. A great excuse for another look...

No... Focus...

While the slime throws quick looks between the two of you, you clear your mind and then your throat.

"There is. But... Are you perhaps busy?" you probe.

She hesitates for a moment. "...Not necessarily. Currently, I'm just following schedule. I can spare a few minutes."

You nod a few times to acknowledge her words. "What is your task?"

"I am tasked with mixing apprentice-level potions for institute inventory," she explains, slyly slipping her name into the conversation. "My name is Liliana."

You grab your chin, feeling like you're on the verge of a good idea.

Experimenting on slimes has always been done in pairs. You thought about dumping this one for the day onto whoever turned the corner, but helping out your colleagues doesn't sound too bad either. Especially since this girl seems to be fishing for some benefits.

"I see... I need an assistant." You point at the slime. "You can forget about your task if you aid me."

Liliana's expression brightens, but she quickly hides it as she fakes some hesitation. While she's at it, she gives the slime a deep scrutiny as well. But the slime just bounces stupidly on the spot at the prospect of a new friend.

"I won't hold it against you if you can't," you tease, pushing the door to your laboratory open. "I'll just find another assistant."

"No, no." she cuts you off. "I was just thinking about my later duties. I'd be happy to assist you, headmaster."

...

The three of you skip past the office of the first room and step through a doorway on the left. There's a hint of sweet in the air inside. Not the nauseating kind, but spices that had been left to dry for later use. Second thing everyone notices are the windows. Squared at the bottom, with rounded tops that take three fourths of the wall's height, placed every few steps so that everything is well lit. In the very back of the room, there's even a small area closed off by curtains for experimenting with light-sensitive materials.

Overall, there are six tables bearing flasks and liquids of all colors, the size of the room easily capable of hosting a few dozen people.

"What are you instructions, headmaster?" Liliana displays her eagerness. Though you believe she's eager for benefits more than for the work itself...

"I just need a second pair of eyes in case something goes wrong. More protocol than anything. This one's well-behaved, so there shouldn't be issues."

"Understood." Liliana's serious tone softens up a little. "Then I'll keep my distance."

"No need. Here." You reach into a buckled bag tied to your belt and pull out a satchet of sugared lemon slices, pouring it into Liliana's hand.

She inspects it doubtfully and can't help but ask, "Candy?..."

Though you confirm her wonders with a nod, she still doesn't know what to do with it. Or why you'd give her candy. Maybe to snack while she stands guard?...

She throws a piece into her mouth, and before she can go for a second, the slime clings to her leg, bouncing like a tiny dog.

"You can feed it." You give her permission, already foreseeing she'd ask for it.

After the momentary surprise, she pinches a slice and hangs it just out of the slime's reach. A few jumps later, she finally drops it, and she can no longer hide her smile.

...

"Smells like cinnamon extract. I think it should be fine?..." Liliana considers after sniffing a flask. "The slime seems to really want this."

On one of the tables, the slime almost vibrates as it goes from flask to flask, using its goo like a straw whenever it gets permission to consume a liquid.

"Star anise... Cloves... Ginger..." you recount aloud everything the slime absorbed in the past ten minutes. "And now this... Just what..."

"Headmaster, is it me or is the slime more... It looks pink, I think."

You draw closer to the slime.

"Indeed. It's more noticeable near the core. And it's not just that." You take a deep breath. "It smells sweet."

"Is it turning into a cake?" Liliana jokes, more comfortable in the way she addresses you. She can't beat the curiosity either and draws in for a sniff as well. "Wow, it does smell sweet."

You squint your eyes, trying to better see the color. So far, it seems to be branching into a brightly-colored variant. It also no longer goes around trying to drink your potions.

It just... vibrates.

The coloration picks up speed once its core changes more of its composition. And soon, the slime turns entirely pink. A bright, lustrous shade that's more discolored than colored.

One that smells...

"Headmaster, it... smells nice." Liliana goes deeper for another sniff. "I wonder how it tastes."

"Enough. Be on your guard. This has never happened before," you scold.

As much as you want to sniff it too, something about it feels off. Liliana's already begun to treat it like a cat, but you dislike enforcing your position for half-assed discipline. So, you just let her be with a warning.

The slime twists its body as if to look at Liliana. She's closer than before, smelling the slime like she would a flower. Then, it moves its goo. So, so slowly. It stands a bit, then reaches forward, until it rests on Liliana's lips. And the sluggishness takes the both of you by surprise.

It definitely understood her words, and it's about to grant her wish.

"..." You pause, baffled.

"Headmaster, it really is sweet..." Liliana retreats, trying to play off her blunder.

"Are you stupid?" you raise your voice.

"..."

While the two of you discover new inner demons, the slime happily wiggles at the compliments.

"Do you feel any different?" You drop your tone a notch. The water's already spilled.

Liliana thinks for a second then nods sheepishly. There's a hint of panic on her face, her breaths taking in more than they let out.

"What is it? Does it hurt? You need to tell me now or I won't know what to give you if you pass out," you emphasize.

She finally lets out a deep breath, but it drains her strength. Her chest shakes as she grasps the edge of the table.

"It's poison... I'm burning... My chest hurts... I-I'm... Ahh... What the hell..."

Chest pain. Burning insides... You rack your brain for antidotes, but too many come to mind.

"What else? Be specific!"

Liliana grits her teeth, her breaths audible with regretful moans of... pain.

"My heart... I don't think it's beating... I can't feel my heart..."

Without hesitation, you place your head onto her chest. Her breasts give beneath the weight of your face, her chest sinking as you press your ear harder to her side. She is unnaturaly warm even through the robe, to the point where she could melt ice with her body heat.

And you listen...

"..."

There's a long silence. Her scorching breaths coat the ends of your hair in droplets of moisture. And this all feels... off.

Finally, there's a powerful drum that sends another shiver throughout her. Finally... You know what ails her... She must've figured it out too...

"...Is it an aphrodisiac?"

Liliana hums in confirmation.

It's your turn to breathe deeply. It could have been any other poison, and you would have the cure for it. But this is a royal institute. Why the hell would it stock cures for aphrodisiacs...

So... you sigh, not really eager to offer help. Other worries fill your mind now. "Take the day off. This cannot reach the ears of those noble bloods. There's a bed in the other room. Rest there and don't let anyone see you."

"Three days..." Liliana counters, grabbing your hand as she gestures a come-along with a head tilt.

"..." You freeze for a second, unsure how to respond.

"Do you have a cure for this?" You turn to the slime in a last attempt, hoping the care you've put into this ungrateful thing will not have been for naught.

The slime quickly moves its rounded top up and down like a nod. Then it tenses, its slimy body turning into a cylinder. Its head widens. Its base... grows two marbles. Its surface bulges with artificial veins. It's...

...A penis.

"Ehehe..." Liliana giggles stupidly as the cock waves happily left and right. But you're so baffled you can't even bring yourself to scold this pink idiot.

"..."

...

You allow Liliana to straddle you, your back resting on the bed after a quick round of tug-of-war towards it. Obviously, it's you who lost. Her robe shows more cleavage as she leans. Her smile warps mischievously, eyes foxy and filled with greed. She's the one in power now. You're the one answering to her and she's not about to let this big fish go.

Closer in she leans, her breath sweet and warm against your face. Her weight feels satisfying, her skin soft and sleek with sweat.

She locks your head in place with her hands as she presses her lips against yours. Once to test for your reaction, retreating to tease you with another look you cannot name, and second to suck the breath out of your lungs. To make a mess out of you.

Again, she kisses you. Deeply and dirty. Her tongue slips into your mouth as you begin to reciprocate the touches. She tastes sweet. She tastes exactly how she smells... Like the slime...

Moments later, you're still locking tongues with her, but a burn courses your body. Your head throbs and a pleasure beyond words saps the entirety of your strength. It feels as if you're flying through an oven.

You crave... Something. Relief and air. Her grinding hips make your legs shake now. Your dick stands on attention with painful twitches as it begs for flesh.

"A week," she whispers in your ear, undoing her robe as she bargains. She planned for this.

Had you known, you would have never accepted to help. But here you are, stripped of your dignity as the headmaster. At the mercy of your underling.

"A week," you whisper back. "But you're not leaving here."

She smiles wider. A week's a week. She'll have plenty time to **** another promise out of you.

"I obey headmaster's orders, then," she playfully says, allowing the robe to slip off her skin.

Slowly, she grasps your hands and guides them to her exposed breasts. Her nipples tickle the inside of your palms as your fingers sink into her flesh. Your hands knead and probe their curves, weighing and pinching, her own pulling at your robe. Her touches on your bare chest feel electrifying. A bolt directly to your brain.

Now you know why she's breathing without letting out. It's the dizzying suffocation.

You want to but you can't. Her teasing taps are **** you, but you wouldn't beg even if it kills you.

Your arms wrap tightly around her, and you wrestle her underneath you as she laughs. You laugh as well. The aphrodisiac is turning the two of you stupid. You find this to be too much fun.

It's your turn to pin and taste her. To sink your lips into her neck. Grind against her and keep her on the verge of begging.

Until you finally want to pierce her. Precum coats half your shaft as you spread her lips, aiming in the dark while your eyes remain frozen in contest. A wordless agreement on who's the first to cede. You purposely miss the entrance a few times and slide along the crevasse, better coating your dick in her sleek liquid.

It's tickling. Exhilarating.

She tries to hold her breath in anticipation. Guess when it will slip in.

You see the frustration on her face as you miss each and every way. The lack of control is a dangerous thrill for her, and she can't keep her breath forever.

When she exhales, your cock magically finds her hole and turns that breath into a shouted moan. Your thrusts carry all your weight behind them, switching tempos to throw off the breathing she's trying to manage. After tricking her a few more times, she wrestles you back underneath her, and she puts you through a breathing exercise ten times worse. You're ridden like a horse and worked like a donkey as she throws her hips down on your lap. Your dick slides in and out without resistance, more and more aggressive.

And finally, you find relief. Your dick pulses out a thick goo with much difficulty, and the two of you collapse on each other.

You wonder if the slime will let you have a bite tomorrow morning too, or if there'll even be any left by the end of the week.
