Hotel Chaldea Ep. Boudica & Reisalin Stout

The alchemist put a bubbling green potion in a teacup in front of you.

It was strange to think that Medea had praised the woman's alchemy to high hell, considering the sort of stuff she could do. She'd claimed that Ryza made her and even her teacher, Circe, look like absolute amateurs, while in turn Ryza would go on for hours about what they could do with what little they had in terms of ingredients.

"You said the name was what?"

"Megacock potion!" Ryza said, grinning brightly. "This is a proof of concept, it should heal erectile dysfunction, increase penis size and massively increase sperm cell count!" she explained, thumbing her nose and nodding to herself. "It should be able to be reproduced with common ingredients that can be found in just about any world that supports human life," she said, raising her finger and pointing at you, "and it also completely eliminates the refractory period while producing a completely safe erection as well as increasing physical and sexual stamina and a bunch of other health benefits like better circulation and other stuff," she said, crossing her arms.

Now, Ryza hadn't exactly broke into your office at an opportune time. In fact, you were in the middle of negotiations regarding providing food for a special event you would be hosting to increase office morale, with the de facto leader of the kitchen staff of Chaldea's Catering Service. Why, exactly, someone with such a high position wandered around dressed in what basically amounted to lingerie, well... Ritsuka was a pervert and that explained it.

"This seems sketchy," Boudica said, "we have homunculi for this, Irisviel can create Homunculi basically indistinguishable from real humans, you know?" she suggested at Ryza.

"Nope! That won't do! I need someone who is a normal baseline human so I can be sure it'll work across dimensions," Ryza explained. "Otherwise I'd have just fed it to Tao and made Patty's day," she hummed, nodding to herself as if she was agreeing with herself, then she cleared her throat. "I am prepared to let you use my thighs to calm your erection!"

You looked at the redhead matronly servant whom you had been discussing logistics with not too long ago.

She looked back at you, looking a little amused but mostly sympathetic. "If you want to we can continue this conversation later."

"Mhm! Well, actually, I could use a second person," Ryza said, smiling brightly. "Just in case I need someone who's strong enough to subdue him in case this triggers some sort of berserker rampage or anything like that," she said. "The chances are low but never zero, alchemy is not a toy!" she said.

"I like how you're just assuming I'll say yes," you snarked at her.

Ryza smiled, took a step back and gestured at her thighs, exposed by her extremely tight shorts, stretched to their limits, slapping the meat of her thigh and making the fat and thick legs that made for one of the best lap pillows to ever exist jiggle from the impact. "I'm not assuming, I know," she said, wagging her eyebrows.

"I hate the fact that you're right."

"Okay, so you just need me to stay?"

Ryza nodded. "Yep! I mean I'm stronger than average but," she said scratching the back of her neck, "I don't have my staff here and besides, I'm specialized for fighting monsters and animals to get materials, not really for non-lethal takedowns of humans, you know?"

Boudica nodded. "Yeah, I understand," she said. "But I'm here so you don't need to worry."

"Should we go to a private room? My office isn't really, you know, private," you said.

"Don't worry, I hung the do not disturb sign before I entered!" Ryza said.

"Okay, fine," you sighed, taking hold of the cup and raising it. The bubbly liquid fizzed slightly, it made an attention grabbing noise as you swirled it slightly, scrunching up your nose before you realized the best way to do this was to plug it before you caught a whiff of any unpleasant smell, so you wouldn't taste it either. Plugging your nose and then downing it at once, it was like drinking carbonated soda, it kinda tickled and stung on the way down at first, but it went down smoothly.

As you put the cup down and unplugged your nose, you were assaulted with the... actually extremely pleasant taste that was a weird combination of just the right amount of sweetness to make you feel it, but not enough for it to actually be sweet like carbonated soda. "That was actually surprisingly nice, it has a wonderful aftertaste even..."

"Alright, tell me if you feel that bubbly sensation-"

"Well, there it is," you interrupted, pushing back so your chair moved back, then standing up off of it, and undoing the front of your pants, pulling them down alongside your underwear. The megacock potion was doing exactly what it was supposed to, within moments your cock was erect and expanding, already going beyond the normal erection and surpassing even what your cock grew into when you used the remnants of old enchantments and potion effects.

In fact, it was... humongous.

"I feel like this could make a horse feel self conscious," you joked, watching with a creeping feeling of uncertainty as your cock seemed to finally reach the apex of penises. If you had to guess it was certainly bigger than some long dead king's foot, and about the width and thickness of not one but two fists brought together. "Why isn't it uncomfortable? This should weigh a lot and make me uncomfortable," you said, reaching for it and hissing as your hands touched the sensitive skin. "Alright I've not lost any sensitivity, in fact I might be more sensitive than normal."

"Ooh, this looks... imposing!" Ryza said, "I guess that's a perfect work huh?" she asked. "Well, I promised, so now I'm going to let you use my thighs to get off! Don't worry, this thing is rated to last three hours, or thirty ejaculations," she said, "well you have a stronger libido so it might last a little longer with you, but all the tests in animals and the volunteers are consistent!"

"Alright then, I've confirmed there's no issue, so-" the redhead queen spoke, as she got up from her chair and prepared to leave, but you reached across your desk and caught her wrist. "Oh? Is there something else you wish to discuss? I... suppose it wouldn't be my first time having an important discussion while the other person is having sex," she admitted.

"Ritsuka?" you asked.

"Ritsuka," Boudica agreed.

Of course.

You snorted. "You know," you said, eyeing Boudica's own mighty and thick exposed thighs. "I want to test something myself."

"What would that be?" Boudica asked.

"There's no way this thing," you said, using your free hand to gesture at your immense cock, "is going to be going in either of you. I don't think anything short of a mare's gonna be able to fit this thing in it," you said, stroking it lightly, "but..."

"I'm not following," Ryza said.

"Oh, you'll see... for now, come along. Ryza, get in front of me with your back facing me, Boudica, get in front of her," you said, moving to the more open space in front of your desk, and standing well at attention.

The two looked at each other.

Ryza shrugged, then moved to where you indicated, but you raised a hand, then pointed at her legs, spreading your fingers in an upside down V shape over your cock. She got it quickly. She was shorter than you but not by much, and only a little finagling saw her successfully swing a leg over the massive iron-hard rod that was your cock, and then closed her legs. She obviously was quite experienced in this but even so, her surprise was palpable.

"Ooh, that's... way hotter and harder than I'm used to," she moaned, "this is... super huge," she muttered, as the impact and weight of her thighs crushing your cock from either side hit your core, it was like a spiraling spear of pleasure that broke through the aegis of your resistance and immediately began applying pressure on your sanity.

It wasn't just intense, it was marvelously intense. Your cock hadn't lost any sensitivity, and the sheer weight, heat and pressure of her thighs on you was incredible... but it was only covering about a third, maybe three eights, of your cock, just under half, despite their immense girth... it was wonderful, but insufficient, you needed, wanted, desired more stimulation.

Getting what it was all about, Boudica chuckled. "You know," she muttered, "I didn't come here today expecting this, but I really should have," she said, directing her gaze at you as Ryza rested her back against your chest, "that looks... fun," she admitted.

Grabbing onto Ryza's chest, you began playing with it. She wanted to use you, so you would use her in turn. Ryza was... well, usually the sort of person who didn't really think that much before she acted, her brain was entirely consumed by her alchemy after all, but obviously, she had her heart in the right place.

Presumably she had one on each thigh, because it really felt like her pulse was super strong near her thighs, or maybe it was your own cock throbbing, hard to say. Her tits were also fantastic, they might not be the biggest, but they were perky yet heavy, full and an excellent pair of pillows to knead and massage.

However, it wouldn't do to ignore the redhead in the room, for Boudica, clad in the glorious white lingerie that she had been convinced to wear exclusively, took hold of your cock and directed it, pulling it down a little so she could more easily step on top of it, pushing it between her legs, letting you feel the soft velvet of her panties, and the impossibly smooth and wonderful sensation of her skin sliding along yours.

Boudica was slightly taller and thicker than Ryza, having wider hips and considerably larger breasts... but most importantly, she had stronger, harder muscles beneath the layer of enticingly erotic fat of her thighs. The pressures they applied were incredibly different, Boudica had a level of intensity all of her own that contrasted tremendously well with the softer but hotter thighs of the alchemist.

"O-Ow, this is..!" Boudica moaned, "ngnh, I've had... many a penis in my thighs but..." she hissed, moaning as she almost stumbled, pushing Ryza against your chest, their chests pressing together for a few moments, before Boudica pulled back, unceremoniously grabbing Ryza's top and pulling it up and off ehr head, knocking the alchemist's hat off.

"Ah, woah, this is- Ngnh!!"

Ryza's breasts were caught and supported by your hands, but Boudica wasn't content to just do that, she pulled off her own top and then pressed her massive titties to Ryza's, their nipples touching against one another, it looked incredible to see, and you could damn near feel it as the throbbing of their clothed pussies reflected onto your cock, their heartbeat increasing and their thighs transmitting it in the form of vibrations onto your cock.

"Fuck, you two are so hot," you growled out, "I'm going to start moving now!!"

Pushing forward first, you were shocked to find that the tip of your cock suddenly felt cold, it was like a great sensation of loss struck you the moment you felt the outside air, the Megacock potion had made you so stupidly large that you actually went right through two of the biggest sets of thighs you could ever lay eyes upon.

"This potion is dangerous," you muttered.

"D-Don't, wo, worry, the commercial, ahn, version," Ryza mewled as an amused Boudica shook her chest, their nipples rubbing against one another's, "won't be so str, strooong!!"

You could feel even through her shorts and panties how truly soaked Ryza was, it was becoming easier and smoother to move, and she was wiggling and rubbing her thighs together which was giving you even more pleasure.

"I would imagine so, this is so big," Boudica moaned. "Hng... actually... can you make it bigger?" she asked.

"Y-Yeah... easily..." Ryza panted, as you tried to regain your breath.

Pushing forward saw your tip finally emerge from behind Boudica, looking snug between all that thigh meat, almost like a cute little purple nub under Boudica's fat ass clad in white panties, already stained darker with your cock juice.

"Goo, good," Boudica moaned, "I think miss Kingprotea will appreciate, that," she panted.

"Even now you still are looking to care for and about others, you're really a lovely woman," you panted, looking at Boudica directly, into her bright blue, almost cyan eyes, "what a stroke of luck, I think I'm getting even more turned on," you said, your cock throbbing between them.

"Y-Yeah, I can tell!" Ryza giggled.

"Then... go ahead... fulfill your dirty desires and fuck our thighs to your heart's content," Boudica moaned, "I can't wait, I want to feel it..." she moaned, her hands going around Ryza and grabbing onto you, pressing the three of you closer together. You kept one hand on Ryza's hip while the other reached for Boudica's behind, and then, you actually, truly, began to move.

First back, feeling once again consumed in all your being by the overwhelming thickness, rubbing against the wet and slick thighs that were lubricated by both pussies' juices, as the queen and the alchemist grew slicker with every movement.

"Ack, why's this feel so good..!!" Ryza mewled, "my boobies and my thighs and my pussy... even though I'm still wearing my pants," she moaned.

Boudica seemed to become inspired at that second, because she grabbed Ryza's red shorts and then unceremoniously tore them off of her, leaving Ryza clad only in a pair of surprisingly cute looking white panties, not quite the same shade of white as Boudica's, but close enough that they almost matched.

Immediately it felt even better to rub against them, the silky smooth fabric of the panties was simply ten steps ahead of the slightly rough and slightly hard fabric of her pants, it was staggering and hard to focus, but you gathered your strength and used all of your focus and sheer will to keep thrusting, back and forth, feeling the impact of the cold air near the base of your cock, then at the tip, then at the base, and trying not to focus on the overwhelming crushing pressure that was threatening to end your very being and consume it in superb softness and heat.

The heat was rising and you felt like your brain was cooking, the pleasure was climbing and you could feel your entire body tremble, your legs growing wobblier with every thrust, until finally it was simply not a realistic goal to keep going anymore.

"Fuck, I'm gonna cum, I'm gonna cum!! I want to cum all over you two!!"

"Do it!! Cum in my thighs, don't hold it back, don't hold it in, cum all over my thighs and my pussy!!" Boudica demanded.

"M-Me too! I want your thick, max quality semen too!!!"

"Gaah, here, here I gooooo!!!"

With that roaring cry, you pushed through all the way until your tip emerged from behind Boudica, then pulled it back as you felt the sensation of your entire body shuddering and concentrating all its strength on pushing the contents of your balls through the immensely huge and powerful urethra.

"AHn, I'm coming, too!!! Your cum's making me cum!!"

Boudica's shout of orgasm was quickly covered by her wordless cry as your semen exploded, not in spurts, but rather, a continuous stream of cum, only mere instants separating each shot, so short in fact that it looked like you were shooting from a hose, only interrupted by Ryza's thighs squeezing the shaft of your cock.

The brunette alchemist couldn't even talk as she came, she simply dropped onto Boudica's chest, clinging to the redhead's shoulders and even taking one of her nipples into her mouth, sucking on it as if looking for comfort while experiencing a mind blowing orgasm.

Your cock pulled further back as you bent your spine to ensure the angle changed, and then, you shoved it not forward, but up, angling it so that it went up between Ryza and Boudica's stomachs, and then their chests, spearing between their breasts. It was so large and long and thick and girthy that it couldn't be ignored, it came up even from the incredible wall of their double titfuck, emerging like a pillar between the mountains that were their tits, and then erupted into another explosion of semen.

The two pressed even harder together, as you came all over their tits, their faces and everything else, after leaving a massive trail of semen from their thighs up their stomachs and underboobs.

"Fuuck, I'm cumming buckets!!" you roared, feeling a little drained as yet another massive load of semen, again a multitude of spurts that joined together into what felt like a continuous stream, before you finally pulled back, sliding along their now cum slick breasts, and sliding down their bodies until your final load erupted within Ryza's thighs, giving her an intercrural creampie just like Boudica's.

You stepped back and watched as they both fell to their knees, clinging to each other and trembling a little.

Panting, you looked down, your erect cock throbbing.

It shrank a very small amount, but, well, it was still bigger than a man's arm. It certainly wouldn't be going in either of them.

Shrugging, you let your pants fall entirely, revealing the just as massively engorged balls, and then stepped between them. They looked quite fuck drunk, but the moment your cock appeared, they regained their senses, taking positions on either side of you, clinging to your legs, Ryza starting to lick your balls, Boudica slowly starting to work her way up your shaft. She'd have to get on her feet to properly blow you, but she was more than happy to do so.

You'd certainly be stress testing the potion quite a bit.

Next time, though, Ryza promised to make sure she'd invent an equally potent potion to allow herself to be fucked by the Megacock.

What a way to learn she was a size queen, huh?
