Isn't This My Chance?

I enter the Alchemy Club, this room could be mistaken with a Science Club if there's no sign above the door. Three workbenches full of laboratory apparatuses, there are several ingredients scattered on the middle one, some kind of leaves, a fruit and is that a horn? Is she in the middle of creating something when she bothered me or did she forgot to clean up?
On the left side of the room is several shelves on the wall, with bottles of unknown liquids inside, everything is encased with glass, to prevent it from being stolen probably. It looks like those potion shops in RPG games. There are also bottles with no liquids like this one in front of me, a head of an insect submerged in sand.
Yep, let's forget about that.
On the right side of the workbenches are two sofas and a table in the center of the two, probably used for meeting guests. Then on the right side of the room is more than ten rows of shelves, full of books. At the end of it is a door with a sign saying 'Secret Archive Room' which is not so secret at all because I can see it clearly from here.
I sit on the sofa while Ms. President enters the secret room. Since I'm already here I'll decide if I'll join or not after I see this club's activities.
"I'm really bothered by the lack of labels on those bottles and books, does she remember everything in here?"
I waited for the president for ten minutes but she still hasn't come out of the secret room. My eyes lands on the soft drink on the table. Now that I think about it I'm really thirsty, and this drink in front of me is labeled 'Click!', one of things I got hooked on after arriving in this world. I already drink the red one while we're in the hospital before and I really like the fruity taste and the yellow one too, yesterday with the trio but I've never seen this one before. A violet one, a flavor I haven't tasted before.
"I FOUND IT!!!" My thoughts were disturb by a really loud voice, I can hear her clearly even when she's inside that room, a very noisy fellow.
She comes out with a smile, walks and stops in front of me, then she put a paper in the table, an application form.
"Wait, I haven't decided to join yet.""Don't worry, don't worry, your soon to be senpai will take care of you." She said while patting my back. "I forgot about the ballpen... let me find one." She left again and went to the workbenches, opening the drawers one by one to find a pen.
She's not listening to me at all.
[Sigh]
"Ms. President can I have this soft drink?" My throat is getting dry just by dealing with her."Okay." She gives me a thumbs up without looking.
[Gulp]
This one feels a little slimy and tastes a little different than the usual fruity flavor, it doesn't taste bad, not in the least but I don't think this is good for hot days.
I drink everything in one go without living a trace, my throat is that dry.
"Hmmmmm..." Ms. President bolts immediately toward me, did she find the pen? "Did you drink the liquid on the bottle?" She shakes me while asking."Yeah, all in one go, you said okay after all." Please stop shaking me."Hah... that was a medicine." She stops shaking me but she have a look that she mess up."Why would you even put a medicine on a plastic bottle?""I don't have any bottles left... I put it in there temporarily, I didn't think you would drink it." You're the one who agreed."This wouldn't happen if you put a label on it, what kind of medicine is it?" I hope it doesn't have a bad effect on my body."It's a libido enhancer for people with erectile dysfunction... Ha Ha Ha..." She laughs wryly."Eh?" Why would you even create that kind of medicine?"Last year, a noble asked me for that medicine." She explains as if knowing the question in my head. "I'm kinda popular back in junior high for creating potions for nobles, then that request came, the request for the medicine you drink... and I strengthen the effect a little that's why I failed." I understand but why is she sweating so much? "The one you drink is a test product I created... in order to perfect the medicinal potion.""How strong is the effects back when you first created the medicine?" It's not that bad right?"Ha Ha Ha... a little strong." She avoids my eyes again. "The client ends up cumming for three days straight." What the hell?
That's no little at all. I'm gonna be okay right?
"Are there any other effects that I should know?" I should prepare myself."It is a lesser version of the potion I created a year ago but I think it still have the same effect, aside from enhancing your libido, it increases your stamina, creates and stabilizes your mana path." Creates mana path? "Let me scan your body."
Her blue eyes suddenly brightens in color as if it was enchanted, I wonder if it will glow if I turn off the light?
"I'm currently enhancing my eyesight with magic to see if there's strange effects on your body." Like an x-ray? That's possible? "Oh!... this is bad!" What! "Most of your mana path is blocked.""Oh... I didn't mention that I can't use magic." Don't make me nervous. "My entire mana path is blocked.""Eh? But there's several mana path on your groin, only that specific part..... does that mean the potion really does create mana path, this is a great discovery." You haven't tested it?"Does that mean I can use magic now? With my dick.""I haven't heard about someone that can use magic with their private part, what are you talking about?" I'm the weird one now. "Also your mana path doesn't reach your mana core at all which is in the middle of your stomach." I didn't expect anything but it's still disappointing."Does that mean mana can flow only inside my groin?" Man, the strange potion really is something."Yeah....." Why is she staring hard at me? "I haven't seen a mana with this kind of color.""?""My bad, I didn't explain, basically mana is a kind of energy right?" I give her a nod. "If you use magic to see its own natural color, it is usually blue... but the moment it entered someone's body, there's a chance it will turn into a different color.""Is there something wrong with mine?""Yeah, it's all black, the moment your mana enters your groin, the color changes to black." Is black bad? "I haven't seen mana turns to completely black before, by the way mine is light green."
I stretch my body a little but I don't feel anything strange at all, except from my dick that is starting to hurt.
"Well? Is there any part that is hurting?""Not at all." I said with composure, completely unbothered."Your dick is twitching." She said with a grin. "Let me see." She positions herself between my legs."What are you doing, woman?""Checking if there's physically wrong with your private part, after all I'm the one who created that potion you drink." She said while opening the zipper of my pants."Unhand me woman, I'm gonna leave.""Are you really sure about struggling? Even if it's only a lesser version, you might end up in a disgraced state while you're walking." That's true. "I created that especially for people with erectile dysfunction, what would happen to an energetic man like yourself after you drink it?" In the end you just want to know the results.
I let her do what she want and she finally opens my pants, my majestic schlong is standing proudly on its grand entrance.
[Gulp]
"Why is this so big? I don't think my potion has an effect that increases size." My dick is literally in front of her face, she stares at it as if she's entranced."It's my normal size and it's only semi-erect.""Does that mean that this gets bigger? It's already twice or maybe three times larger than him. What would happen if you're fully hard?" Who are you comparing it to?
She starts sniffing my dick, savoring its smell then she give me a calculating smile.
"Isn't this my chance?" She puts her left hand and started slowly stroking it. "Hey, Touya do you really want your senpai to take care of this?" Why is she asking me? "Then promise me you'll sign the application form." This conniving woman."Ugh...""Wow, it's really getting bigger." She said with excitement. "What are you gonna do? There's no time to find a woman that will take care of this for you." She started stroking harder."Fine... I accept, I'll join the club... you devilish woman.""Heh." Stop with your winning smile.
