What Do You Mean There Are Other Transmigrators In My Harem Fantasy?

I was attending my alchemy lesson with Lisa today and she was still making us craft a health potion since no one else has succeeded except me so far.

That doesn't mean I was doing nothing however, since Lisa had challenged me to make the potions as quickly as I could.

I still can't get used to the fact that she has this serious persona during alchemy classes while she's usually so flirty and unrestrained outside of it.

Sure, she sometimes still sneaks to the back of the class where I was and would start caressing and whispering dirty stuff into my ear but she always made sure that we were never caught doing it. In front of the other students, she was just as strict on me as she was with the others.

Although it was still clear that I was her favourite since I was doing exceptionally well in her classes to the point that she would ask me to stay back for extra classes.

Yes… It was those kinds of classes…

And here I was, just finishing up my latest batch of the health potions and feeling proud that I managed to shorten my time by half a minute when a pair of hands wrapped around my waist from behind.

It's only because I've already experienced this a few times that I managed to keep myself from screaming out in surprise.

"Ahhhnn~ My dear Aster~ It seems like you've improved again~ Just seeing how serious you look while brewing these potions is making me so hot~ Are you busy after class?" Lisa whispered in my ear from behind.

"Let me guess… You want me to stay back again after class again?" I whispered back.

"Ehehe~ You know me so well, Aster~ So… Would you like to stay back after class with me?"

To show exactly what she had in mind, one of her hands slipped underneath my skirt to run a finger along my pussy through my panties, continuing upwards past my balls and tracing along the length of my cock to stop at the head.

Feeling my cock twitch at the contact, she grasped it with her hand and stroked it a few times through my penis sheath.

I shivered at the pleasure she was giving me and nodded my head, not trusting myself to speak.

She giggled and planted a kiss on my neck, "Ehehe~ I can't wait for you to bend me over the desk and fuck my pussy~"

She kissed my neck one more time before pulling back, changing back to her serious persona before strolling back to the front of the class.

"Aster has already managed to make the potion half a minute faster than before, has anyone at least managed to complete one?"

No one responded though a few turned to give me looks of awe and jealousy.

She then turned to look at me, "Aster, stay behind after class. I'll give you some pointers on how to improve your brewing process."

"Yes Professor," I replied, my cock twitching in anticipation of the session we'll have later.

The lesson continued as per normal and as usual, no one else managed to brew a proper potion yet.

Lisa gave everyone else alchemy topics that they should research and practise on before letting the other students leave the class for the day while I stayed behind.

When the last student exited the class, Lisa went ahead to lock the door and windows again, turning back to me while licking her lips.

No words were said as she went to the teacher's table before bending herself over the desk, her hands reaching back to pull up her skirt to reveal her panties to me.

I approached her from behind and hooked my fingers underneath the straps of her underwear, slowly pulling it down and marvelling at the clear liquid that stuck to her panties that showed how turned on she was.

I couldn't help but squat down to put myself in a position to latch my mouth on her pussy, sucking on her honeypot as I tasted her juices with my tongue.

"O… Ohhhh~ Oh, by the Gods… Aster… Aster is going down on me… Nnngghh!! Your mouth… It's so good…" Lisa moaned, her body shivering in pleasure.

My tongue darted out and flicked against her entrance, causing her to let out a yelp of pleasure.

Spurred on by her reaction, I started licking her entrance by moving my tongue in circles as I pleasured her with my mouth, slathering her pussy with my saliva.

She started to shake her hips against me, trying desperately to get herself off with my tongue even as her hands reached down to start pumping her own cock.

I felt something brush against my crotch and I paused to see her tail snaking in between my legs to wrap itself around my cock.

"Unn… Don't stop, Aster! Please! I'm so close!" She begged, pushing her pussy against my face again.

I obliged her and went back to licking her pussy while spreading open my legs to give her better access to my cock.

I sped up the momentum of my tongue and her tail responded in kind, pumping my cock as fast as I was licking her pussy.

Surprisingly, I made her cum first as her juices squirted into my mouth while her seed spurted into her penis sheath, the Infrid moaning out in pleasure while in the throes of her orgasm.

I wasted no time in standing back up, lifting up my skirt and positioning my cock to line up against her entrance.

Lisa was still in the throes of her orgasm when she felt me press my cock against her entrance, "As… Aster? What are you…"

I thrusted my hips forward and sheathed my entire length inside her in a single thrust.

"Hnngaaahhhh!! Asteeeeerr!!" She screamed, her pussy tightening around my cock with a vice-like grip.

I let out a moan of my own as I started thrusting my hips against her, sliding my cock in and out of her sloppy, wet pussy.

Reaching forward, I grabbed onto her bosoms with my hands and started groping her boobs, massaging them and causing her to moan even louder.

Lisa's hands moved up to cover my hands with hers, tightening her grip to make me squeeze her boobs even harder as I continued to fuck her from behind.

"Hnnggg! Harder, Aster! Fuck your naughty teacher in her own classroom! Make her cum over her desk!!"

She started pushing back against me to match my movements, slamming her hips against me and filling the room with lewd sounds of our hips slapping against each other.

My focus was on my cock as her pussy started to tighten even more around it, desperately trying to milk me of my seed as it massaged my entire length like it was alive.

​ I felt the familiar pressure building up in my balls and I knew I was close.

"Lisa… I'm going to cum…" I warned her, though my hips continued to thrust against hers without slowing down.

"Yes! Yes! Cum!! Cum inside your slutty teacher Aster! Fill her up with your seed!!"

"I'm… I'm cumming!"

I thrusted my hips one more time before I felt pleasure overwhelm my senses. My balls tightened and I felt my cum shoot out from my cock and into my penis sheath that was inside of her pussy.

The pussy walls around my cock constricted and relaxed around my length, coaxing every bit of cum out from my shaft.

I shuddered as I felt myself empty inside of Lisa's pussy, her hips still thrusting against mine even while I came.

Only when she was sure that I had finished cumming did she stop moving her hips, allowing me to take a step back and pulling myself out of her.

A bulb had formed at the tip of my penis sheath as my cum sloshed around inside of it, the enchantment already slowly absorbing it and sending it as an offering to Hiandoca.

I looked up to realise Lisa had turned back around to look at me with heart shaped pupils, her ring pulled off to reveal her true form.

"More~ I want more, Aster~"

She reached down and pulled off my penis sheath, revealing my naked cock that was still throbbing with need.

She leaned back against the table and spread her legs, her tail wrapping around my waist to pull me towards her.

"Li… Lisa?"

"I want your cum inside me, Aster~ No sheaths, just bareback sex~"

She jerked her tail and I was pulled the last few centimetres towards her, causing me to penetrate her.

She moaned and wrapped her legs around my waist, cutting off any means of escape as she started shaking her hips against me.

I could do nothing as she grinded her hips against me, the Infrid moaning out in delight as my cock rubbed against her insides.

"Breed me, Aster~ Fill me up with your babymaker! Breed your slut! Your naughty slut wants to be filled with your cum!"

She increased the pace of her hips, slamming herself down on me over and over again while gyrating her hips to increase the pleasure I was feeling.

I could feel the tip of my cock kissing against the entrance of her womb, practically begging me to fill it with my cum.

That proved to be my breaking point as I came again, this time shooting my sperm straight into her waiting womb.

Lisa let out a scream of delight as she came with me, her cock twitching in between us as she spurted out her seed into her penis sheath.

My mind went blank with pleasure and it took me a moment before I came back to my senses, my cock still twitching inside of Lisa's pussy.

"Mmmm~ We should just have bareback sex from now on, Aster~ Feeling your cum inside my womb is so much better~ I'll have to brew more of those anti-pregnancy potions~"

Well, I have to admit it does feel good to know I was flooding her insides with my cum so I suppose we could do that…

"Now, let's continue until your cum is dripping out from in between my legs!"

Ah… I knew we weren't done yet… I hope I don't pass out this time…
