SI x Virgo

Summary: A man was reborn into the world of Fairy Tail… as Lucy Heartfilia.

After years of searching, I've finally done it! Body Change Magic, a magic that focuses on modifying the body to make it more efficient and powerful. It's a lot like Take Over Magic, except the user doesn't need the "soul" of another being and the effects are permanent unless the user uses their magic again to change back.

It's theoretically more powerful than Take Over Magic because there is no limit to how you can mix and match your body to create a more and more powerful form. Except, Body Change Magic requires the user to understand not only the human body but also the biology of anything they want to change/incorporate into their body and how it would interact with their body. This severely limits the power of most Body Change Mages.

Not for me though, as a reincarnator and a Biology Major, I already had half the requirement to do the magic. It was why I chose to learn this magic in the first place.

With my knowledge of the human body alone, I was able to make my body faster, stronger, and more durable than anyone ever before. I was able to reach the peak possible physique of the human body, not Olympic level, nor even peak human of Earth, but the peak human of Earthland, which is to say, I'm bullshit level strong. At my current point, I can lift a ton without breaking a sweat and that is without using the most basic of Body Change Magic(Body Enhancement Magic) to boost my power. In fact, with the changes to my body, I might even be biologically immortal… though there is no way to test that besides to continue living.

Despite the power though, that's not the reason I choose to study Body Change Magic. I did it because I, as a man, was reborn in the body of one Lucy Heartfilia of Fairy Tail, I was reborn as a girl…

Now, after years of searching and learning Body Change Magic, I finally gained enough skill in the magic to change my gender.

"Body Change Magic: Gender Change!" I call out, casting the magic I've been waiting years for.

In a flash of yellow light, my body starts to shift and morph. My admittedly well-endowed chest starts to shrink, my muscles become more pronounced, my hair shortens, my face turns from what would be called beautiful into handsome, and last but definitely not least, I gain my "little" bro back.

I feel like crying tears of happiness right now.

"Congratulations, Master." My pink hair maid and Celestial Spirit partner, Virgo, congratulate me.

I took her from Everlue years ago with Aquarius's help. Ever since then, she has become my go-to summons for... well, almost everything. And unlike Aquarius, she doesn't mind being summoned for niche purposes so I summon her when I just want someone to hang out with, need someone to help clean the house, or want some training, among other things. I still do summon Aquarius but due to her tendency to be... violent, I only do so in battles where there's a big body of water nearby.

I can even keep Aquarius around for as long as I want because my Magic has grown that much to sustain her by myself. I inherited Lucy's talent for Celestial Spirit Magic, making it a lot, and I do mean A LOT, easier to cast Celestial Spirit Magic than Body Change Magic. It took years of studies to master Body Change Magic but I was able to use a Gold Key without any problem as soon as I got my hands on one.

"Master, as you have instructed, I am to tell you once it's July. It's the first of July, Master." Virgo says in her usual stoic manner.

"Ah, right. Thanks for the reminder."

Unlike the original Lucy, I ran away a long time ago. The first thing I did was change my name to Lucius and dye my hair black so Lucy's asshole of a father won't be able to find me. Since then, I've been staying in Hargeon Town training my magic and waiting for Natsu to show up. I've also been doing odd jobs as the only mage in the town to earn my living.

While I could have just gone to Fairy Tail and asked to join, I didn't do that because I wanted to wait until I'm a guy first. I doubt the guild will care if one of their members suddenly changes gender overnight but the first impression is important and all that.

"Does that mean it's time for punishment, Master?" Virgo asks with sparkling eyes despite her stoic face. She's also holding up a set of bondage gear and some candles she pulled out of nowhere.

"You know what, why not. You've earned it." I said, taking her gears from her. I've long grown used to her masochist nature and even helped her indulge in it multiple times.

"Come on, let's go to the dungeon," I say, leading the way to the "dungeon", aka, my basement decorated with the various bondage stuff Virgo collected over the years. There are even stuffs there that are too extreme for me to even want to try on Virgo despite her masochist tendency.

"I can't wait, Master!" Virgo exclaims as I lead her down the stairs.

Half an hour later, Virgo is tied up, naked, and gagged while on a triangle wooden horse. The ropes around her wrists and ankles are connected to a wooden bar on the ground and then up to the ceiling. She's bent forward with her ass in the air. Her legs are spread apart, her pussy pressed against the wooden horse, her breasts hanging free, and her face flush with both embarrassment and lust despite still looking as stoic as ever.

She's completely exposed and helpless just like she wanted.

I'm standing in front of the horse with my dick out stroking it. Virgo's eyes are glued to my cock the entire time as I stroke myself to a full erection. The sight of Virgo in this position excites me to no end. Despite having seen this scene for years, seeing her like this still makes my dick hard. I even use a bit of Body Change Magic to make my dick grow a few extra inches just for Virgo.

"Are you gonna fuck me, Master? Are you finally going to punish my pussy?" Virgo asks through her open-mouth gag. This is the first time we did this when I have an actual dick. She no doubt wanting to feel it inside her.

"No, that would be rewarding you. Instead, I'm going to fuck your asshole without any lotion." I reply, taking a step toward her.

Virgo shudders at the thought.

"Don't worry, I'll just use your saliva to lube myself up instead," I say, stopping in front of her with my dick in her face.

Virgo inhales deeply and moans softly, her tongue poking out of her mouth through the hole of her gag, wanting to get a taste of her Master's dick.

"That's a good girl. Now, lick my dick clean and get ready to take it inside your ass." I order, placing the head of my dick in the opening of her gag.

Virgo obediently sticks her tongue out and starts licking my dick. The feeling of her warm tongue against the tip of my dick makes my cock twitch and throb, desperate for more stimulation. It feels great to have a dick again.

"Mmm... Mm..." Virgo moans as she licks my dick while dry-humping herself on the wooden horse.

"Good girl, now opens wide so I can fuck your mouth," I say, pushing the head of my dick into her open mouth. Not that she needed to do anything with the gag keeping her mouth open for me to use. I push my dick deeper into her mouth, making her choke on the shaft of my dick as I push into her throat. Despite my dick being at least 10 inches now, Virgo is able to take all of it like a champ as she makes use of her transformation magic to change her mouth and throat to perfectly fit me.

"Aah! Aaaaah!" Virgo gasps as I stretch her mouth further than it should go. I pull back just enough for her to breathe, not that she needed to as a spirit, before thrusting my dick deep in her throat again. I grab onto her hair, pull her head back, and start fucking her mouth with long, rough strokes.

"Mmmm~!" Virgo moans loudly, her voice muffled by my dick.

My favorite part of the whole process is that every time I shove my dick down her throat, Virgo gets off on it.

After a few minutes of this, I pull out despite how good it feels. I'm just using her mouth to lube up my dick in preparation for taking her ass after all.

Virgo looked on reluctantly as my dick left her mouth.

I chuckle, "Don't worry, now that it's all nice and lubed up, I'm going to fuck your ass properly." I tell her as I lower the wooden horse to give me better access to her ass. I walk towards her back and grab onto her hips, lifting her up slightly. With Virgo in place, I let my dick rest right between her ass cheeks. Virgo turns her head to look at me. I can see her eyes glimmering with anticipation, waiting for me to impale her.

I grin wickedly, "Time to get fucked."

With one swift move, I stick my dick into Virgo's tight ass. Virgo screams loudly as my dick stretches her asshole open wider than ever before.

"Ooohhh~! OHHHHH~!" Virgo cries out, tears forming in the corner of her eyes from the intense pain that only registers as more pleasure for her.

Her pussy is already dripping wet with her juices as I penetrate her. Her orgasm hits almost immediately.

Once I bottom out inside her, I slap her ass, eliciting another scream of pain that turns into a moan of pleasure. Her stomach is bulging from the size of my dick every time I pound into her tight little ass. When I do, I also make sure to continue slapping that ass to keep her on edge.

"Mmph! OOOOHHH! Nnhhh! Mmm! AHHH~! MASTER! AAAAAAAAAAAAAAH!" Virgo cries out, her body shaking as she cums uncontrollably.

As I fuck her ass, I grab Virgo's hair and pull her head back as hard as I can. Her asshole clenches down on my dick even more as I do that, she's almost painfully tight. I can see her muscles bunching up around my dick, trying to push me out every time I pound into her.

"Ah- Ah- Ahhhhh- YEEESSSS!" Virgo cries out, her orgasm keeps on building up inside her body.

I pull away just enough to be able to pull her head back further and give her a savage kiss. Virgo moans as our tongues collide together, her pussy still squirting out juices as I fuck her ass even harder.

It doesn't take long before I reach my own climax.

"Here it comes, Virgo," I warn, my voice strained. I push deep inside her one last time before cumming in her ass. My entire body tenses up as I shoot my entire load of hot cum into her bowels, filling them up with my seed.

'AAAH! AAAANNND!' Virgo screamed, her orgasm reaching its peak, her eyes rolling into the back of her head as her body shakes with the intensity of her orgasm.

We stay like that for a few minutes before I feel her ass milk the last of my load out of my dick and she calms down a bit from her high.

When we pull apart, Virgo looks at me still with lust-filled eyes, the cum leaking from her gaping anal cavity.

"If you're done with that, Master, I'd love to get fucked in the other hole now," Virgo says, her tone sounding desperate for more.

I laugh, "Of course, my dear. As would I."

I put Virgo down on the floor and turned her over on her back. With her still tied up in her bondage gears, she can do nothing but lie there as I use her body however I want. I lay on top of her, spreading her legs wide as I entered her. With how wet she is, she had no problem taking in my dick despite its size.

Virgo moans as I fill her again and her body shivers when I press my hand against the bulge my dick made on her stomach. This time I reach down and grab her small breasts, pulling and squeezing them as I begin pounding her. I move in and out of her pussy with slow, steady strokes, allowing her to feel every inch of my dick inside her. She moans deeply as I do so, her breasts bouncing slightly with each thrust.

"Mnn... Mm! Hahaha..." Virgo moans.

I let go of her tits and grab her waist, as I start moving faster. I slam into her pussy harder and faster, causing her to cry out from the intense pleasure. Virgo's face contorts in a grimace from the intensity of it all as I pound into her like a jackhammer, making her cum for a second time.

"Aaaaah! AH-HA-AH-AAHHH~!" Virgo screams as her orgasm rips through her body, her juices flowing freely from my cock.

I keep fucking her pussy until I release yet another load deep inside her, filling her with my seed. The combination of her cum and the cum I just shot makes her pussy even more lubricated, allowing me to slip right out without any trouble.

I grab Virgo by the hips, pick her up, and place her on the nearby table on her stomach with her ass out. With a small application of magic, I'm rock-hard again and ready to go. I slam my dick back into her pussy, causing her to cry out from the intensity of it all. I grab her hair and pull her back as far as I can, her back arc, leaving her no choice but to take my entire length inside her.

"Yeees~!" Virgo cries out, still hasn't come down from her second orgasm yet.

I fuck her hard and fast, slamming my dick deep inside her over and over. I feel Virgo's pussy gripping my dick tightly as if trying to milk every last drop of cum out of me. I notice that the cum leaking from her ass has run down her thighs and onto the table beneath her.

"Ah- Ah- Mnnnnn! AAAAAAAAAHHH~! AAAH!" Virgo cries out, her body trembling as another orgasm hits her.

I hold her hair and push her face against the table, smothering her while I continue slamming into her. Virgo moans from the overwhelming sensations, her entire body shaking as she cums again.

After another few minutes, I stop ramming into her and instead pull out. I grab my dick and force it into her ass, pushing my entire length inside her. Virgo yelps from the sudden intrusion, her asshole not prepared for my dick. I start pumping my cock in and out of her ass, forcing my way deeper each time. Virgo groans loudly, tears forming in the corners of her eyes as I continue plowing into her ass. She moans in pain and pleasure at the same time as she takes my entire length inside her bowels, all the while cum continues pouring from her pussy.

I keep doing this for a few minutes before I pull out and shoot my load all over Virgo's back, painting her with my seeds. Virgo collapses on the table panting, finally getting a break from her continuous orgasm. She feels the cum dripping from her pussy and arches her back, moaning from the sensation.

I look down at her and smile, "That was nice, wasn't it?"

Virgo nods weakly.

I patted her head, letting her know she did well. "Make sure to clean all this up. I have a few things to prepare." I tell her before I leave, knowing it'll only take a few minutes for her to recover despite the intense fuck she just had. She can recover even quicker if I give her more magic or send her back to the Spirit World.
