MLP: Unlimited Blade Works

---Saber---

I push our bedroom door open, and gently lead my two beloved former Masters inside. They DO owe me afterall, and I’m still hungry for “dessert”. I can already tell the two are quite excited for the prospect.

“Well someone’s eager…” Rin said dryly with a smile.

“As if you’re any better.” I retorted just as dryly.

Shirou just found this whole situation amusing judging by that small smile on his face, one day I will see a full-blown grin on his face!

Rin didn’t deny it, in fact she shrugged as best she could as I tossed them both lightly onto our bed and I prowled into the bed no doubt looking like a giant scaly lion on the hunt.

Rin smirks at me, as she begins to shapeshift.

Oh! This might be interesting…

Shirou watched curiously as well, his mottled black stallionhood already standing at attention and throbbing smacking his belly with each jerk.

… When the ‘green fire’ disappeared where a mature mare was now replaced by a snow white filly with ruby red eyes and what looked like a Japanese two-piece swimsuit!

“Onii-chan?” She asked with wide eyes.

… I believe the proper phrase to attach to Shirou’s reaction is… “Why Boner: With a Vengeance” but I might… no. I am right actually. I even giggled a little when it jerked and spurted out a gob of pre…

… Either he has an unrealized incest fetish… or he’s a lolicon in denial or something along those lines…

“Onii-chan? Can I play with you and Art-nee-chan?” The faux-Illya, or rather Rillya, asked as she pranced over acting like a playful energetic filly.

I blinked in surprise; did he just get harder?

Shirou can only stare mouth agape, as Rillya prances over, and nuzzles his shaft. Eyeing Shirou, she kisses his tip. “Onii-chan’s penis tastes wonderful today!” she giggles.

“Oh Root…” He groaned.

I for my part gaped slightly, did he nearly orgasm just from that!? Well… this is an interesting turn of events…

Granted, considering what I did with Mordred behind closed doors, I’m not one to talk.

Anyway I decided that I had sat on the sidelines long enough and resumed my prowel up to the two of them, “Illya-chan can I join you?” I asked, deciding to play along as well.

I briefly entertained the thought of using that “Lilly” spell the Dick Magus taught be but honestly I don’t want Shirou going off prematurely. Though I am very, very tempted… perhaps next time? Yeah… next time. Maybe I could summon the other Arturias to help. For his birthday.

Rillya nuzzled Shirou’s ‘sword’ again, “Umm… I guess…” She said with a pout, “So what do you want to do Art-nee-chan??”

I looked at Shirou, who seemed to be stuck in some sort of mental loop of sorts, and decided that my decision on not to use the “Lilly” spell was indeed the proper one. He’s probably wind up choking on his tongue or something!

I wonder what to do at this point. Should I assist her in sucking Shirou off? Should I eat her out? So many options to choose from..

Ultimately Rillya took the choice out of my claws and bopped me on the snout with his cock while she bent down to inspect his testicles, where were no doubt aching currently. He cock certainly looked like it was distressed and confused.

’Why-boner indeed.’ I thought as I took the flared cockhead into my maw with practiced ease. My forked tongue trails along his length as I slide it in and out of my mouth.

Shirou’s head just lolled back as her gentiles were attacked by a loli Rillya and myself, I could only imagine what he’s thinking.

---Shirou---

Today I learned things about myself. The first was that I apparently found Illya-chan attractive. The second was that my, albeit adopted, sister or a facsimile of her was getting me aroused. Truly, my mind had become distorted.

So, so… painfully distorted...

That, and every part of me is screaming this is wrong. Then again, if I just imagine its Rin, and not Illya, maybe it’ll be alright. I must not prove Illya-chan and Child Gilgamesh right. Control your penis Shirou, focus on Rin, and Arturia. That’s it, good penis, you’re not attracted to Illya.

Oh dear God and the Root, I’m mentally talking to my penis.

… Rin and Arturia must never know....

---Saber---

Eh… I’m sure he’s fine.

Deciding to shelve the thought I focused on the task on swallowing this ‘sword’ and despite all the practice I’ve got with Rillya in the mix it was proving to be something of a challenge

I noticed out of the corner of my eye Rillya raise her head up, revealing both delicate orbs liberally coated in saliva, and she smiled.

It was a devious one aimed purely at me.

“Onii-chan tastes so good!~ I can’t wait for Onii-chan to force his giant cock into my undersized fillyhood and cums lots!” Rillya said eagerly.

Shirou’s balls tightened, his cock jerked, and I choked as an unexpected flood of seed spewed down my throat like an uncontrolled fire hose!

I gag a bit but swallow his load down, as I have in the past. I kiss his tip in thanks as I swallow, and remove his shaft from my mouth as I look at him. His expression, and blush, is a mixture of embarrassment and shame. Absolutely adorable.

“Um… oops?” Shirou said sheepishly, which honestly sounded adorable to both Rillya and myself.

“Art-nee-chan! I wanna taste too!~” Rillya whined, and I am in awe of her ability to stay in character.

I grin, and then eye Shirou, before I lock lips with Rillya. Her tongue dances with mine, as she licks up the bits of Shirou’s sperm that hadn’t been swallowed.and just like that his stallionhood, which was flagging slightly, returned to its former rigidness.

“Mmm… nee-chan!~❤” Rillya cooed.

I’ll admit Rillya’s act was so convincing I felt this thrill over doing this dirty deed! I mean… Mordred is one thing but still…

However, as I opened my eyes, I found Rillya had once again shapeshifted. Into a dragonling Mordred. Oh… oh my…

I then notice that I must have subconsciously activated the futa magic Merlin had taught me, for now I have a seven inch penis and balls, right above my dragonesshood. And its currently erect.

Right, I forgot Changelings have an empathetic connection to any and all erotic thoughts. But, maybe I can work with this. I’ll let Rindred make the first move.

Shirou was just watching with clear interest, apparently now that Rillya was gone he felt more comfortable. Or perhaps less awkward. Honestly I could see how he’d be uncomfortable and awkward… Rillya indeed inspired Why-boners easily.

It was when I was distracted by my thoughts did Rindred pounce on me.

And in short order Rindred was swallowing my cock down her own maw making me moan as I petted her head.

Shirou snorted before he got up and mounting Rindred and after moving her tail out of the way pressed his flared head again her pussy and started to slowly and steadily push his way inside. Rindred certainly didn’t mind in the slightest but I smirked as an idea came to mind.”

“Shirou. Lay down on your back, Rindred I want you to mount Shirou.” I said.

Shirou, blinded momentarily in confusion before understanding came to him and he did as I told him. Rindred seemed more reluctant but she did as well, standing up and slowly guiding Shirou’s penis inside her gasping as she slowly lowered herself.

I then teased her asscheeks, as I plunged my throbbing femcock into my lover’s defenseless anus. Rindred moans, “Oh daddy! Fuck me harder!” she pants, as I and Shirou bounce her on our thick penises.

“Oh you want it harder? I can do that!~” I cooed to her before I started to really leverage my draconian strength to ream her ass hard.

Sadly Shirou wound up just being along for the ride instead of an active participant but I don’t think he really minded much.I slam my shaft again and again into her, my balls slapping against her asscheeks.

I don’t know if it was Rindred, Rillya’s previous performance, or a combination of both but I found myself reaching the limit before I forced as much of my cock into her, causing a bit of a bulge.

I let out a trill-like moan, as my draconian semen filled her bowels.

I panted, pulling out, as small rivers of my seed spurted out of her hole. Rindred panted softly, rubbing her slightly bloated belly. “Oh daddy, I feel so full now!~.” she giggled.

Rindred than yelped when Shirou flipped them and started rutting hard into her, having not climaxed himself. And judging from the pace he was setting and the snorts he was making it was something Shirou had decided to correct post-haste. Granted, judging by the calendar, and what I know of the various species on this planet, all three of us are in, or very close to, our heat cycles.

Hopefully Rindred doesn’t get pregnant… or myself for that matter cause I know I’m next in line for a rutting. Not that I, and I’m sure Rin as well, wouldn’t mind being pregnant but perhaps once we’re married to Shirou.

Hmm I wonder what sort of wedding it would be… probably a small private one. Though I imagine Pinkie would want to make it a large party… that crazy mare.

I was pulled from my thoughts by a neigh followed by a trill as Shirou hilted himself as far as he could and came, I could even see his balls contracting! Just how riled up had Rillya made Shirou? I’ve never seen his balls do that before… and I’ve had close encounters with them both in this and our past lives.

I’ve never visibly seen them do that before! I thought that only happened in those dirty videos Medusa would make me watch…

I was, yet again, pulled out of my thoughts only this time my Shirou gently pushing me onto my back, mindful of my wings, before he lined himself up and started to work his way into me. And my moans were cut short as Rindred mounted my snout and started rutting her creamfilled cunt on me.

I smirked, as I could taste her juices and Shirou’s semen mixed together like ice cream. My long, forked tongue began lapping at her delicious snatch.

Tonight is a rather good night… and I got my dessert as well!
