*For the sake of this fic, I'm going to pretend that nobody's a virgin prior to this fic because even I have my own morals. That being said, onward to the porn. NSFW from here on.

It was Gladio's voice that woke Ignis up instead of his own internal clock. "I don't want to wake them up. You wake them up." Strange. Ignis was always the first one to rise. He could feel the warm sunlight on his back and for the briefest moment tried to remember why he was sleeping outside the tent on top of it being so late.

"This is your stupid potions fault, so you wake them up," That voice was new. It sort of sounded like his, but lacked an accent. His eyes fluttered open, the only thing within his sight was the back of Prompto's blonde head.

He reached around for his glasses, hoping they hadn't broken when he collapsed. His hands scanned the rock sleepily for a moment before he realized that his sight was perfectly clear. He blinked hard before turning his head and looking in the distance behind the haven. Everything was in pristine, crisp, detail. Perhaps that odd potion had completely fixed his sight. He reached down and shook the blondes shoulder. "Prompto, wake…" he cleared his voice. It sounded strange. "…wake up your potion appears to have fixed…" he cleared his throat a second time. What was wrong with his voice?

He felt Gladio's presence next to him as the larger man crouched down. "Iggy? That you?"

Ignis turned his head toward the shield to respond, but his voice caught in his throat before he could articulate an answer. He, Ignis, was standing behind Gladio, looking at him with an expression of confusion that he found alien looking on his own features.

He shot a look between the two of them. Gladio looked downright guilty. An odd expression for him as well. Ignis rubbed his eyes, he must be dreaming. Still… "Could someone please explain what the bloody hell is going on right now?"

Gladio nodded. "Yup, that's Ignis."

"Well of course I'm Ignis." He pointed at his doppelganger behind Gladio. "Who is that?"

Gladio laughed nervously. "That… um… That's Noct. And he…" Gladio pointed at the now stirring blonde. "…must be Gladio. I think that mega potion I bought wasn't the healing kind of potion."

Ignis gritted his teeth and slid his fingers up the bridge of his nose to adjust the glasses that weren't there. By now Gladio in Prompto's body was stirring. Ignis tried his best to keep an even tone. It wasn't Prompto's fault. Honestly, he should have read the bottle before they used it. "Well… We'll just have to go back to Lestallum and find the shop that sold it to you. It's likely they have an antidote of some kind."

By now Gladio was awake, his blue eyes staring wide eyed at the others. "What the fuck?"

Prompto gave Gladio the same nervous smile he'd given Ignis. "Mornin' big guy."

Gladio shot to his feet and looked down at his lithe form. He glared at his former physique then back to the freckled torso he was currently occupying. "What. The. FUCK!?" he yelled again. He looked at Noct, "Ignis, what's going on right now."

Noct pointed to Ignis, "Over there, Gladio."

Blue eyes darted around the campsite in confusion. "Ignis?" He said to the raven-haired youth.

Ignis sighed. "So, it would seem. Let's break down camp and start heading toward Lestallum before the day grows any more confusing. We'll try and figure things out on the way."

A few hours later they were walking into the Leville after cashing in their griffin hunt. The only room left available for all four of them was a two-bedroom two-bathroom suite. It was a more Gil than Ignis wanted to spend, but they would just have to take on another hunt once this was all sorted out to pay for it. Prompto offered to put it on his credit card. Ignis told him that if they had to stay more than one night he would take him up on the offer.

As they entered the room, they let their bags drop to the ground heavily. They were all still filthy, lightly injured, and exhausted from the previous day.

Gladio looked at himself in the oversized mirror on the wall and groaned. "I'm so glad we already dropped Iris off at Caem. I don't know how I would explain this to her."

Ignis ran a finger up the bridge of his nose to adjust the glasses that weren't there for the sixth time today. "Good point." He looked around at the others. "Don't get too comfortable. We need to find the shop, if its open yet, and get some answers before…" He smelled the air and his mouth watered. "Did one of you put coffee on already?"

Everyone shook their heads. Ignis made his way to the kitchen and found the small coffee pot cold and empty. The room, however, smelled like a mind morning café to him. "Does anyone else smell that?"

They all sniffed the air.

Gladio said, "I smell leather and roasting meat."

"I smell Noct's cologne," Prompto said.

Noctis inhaled deeply and let out a content moan. "I smell the docks from Insomnia," he sniffed again. "Bait shop and everything. The hell is going on? Another side effect of the potion?"

Gladio smelled his way around the room before coming upon Prompto's bag. "Hey Prom, your bag is leaking some pink stuff."

"Pink stuff? I don't remember packing anything pink." He opened his bag and moved things around before gingerly taking out a broken vial. "Woops, guess I put the bag down too hard."

Ignis took the vial from the larger Prompto and read the label. The pink liquid was quickly evaporating into the air, though for Ignis the smell of coffee only got stronger. The label was smeared and written in swoopy, romantic writing, but finally Ignis managed to make out the word Concupiscentiam. He swallowed hard. "Prompto. Was this another potion from the same shop?"

Prompto nodded, "Yeah. Why?"

Ignis grabbed a dish towel and wrapped up what was left of the broken vial in it. "We need to find that shop. Now."

Prompto whined and slumped his enormous shoulders. "Do we have to this second? I wanted to shower first." He mussed his mane. "Gladio's filthy."

"Hey!" growled the blonde. "You would be too if you did any work."

Prompto stuck a tongue out at him as a retort.

Ignis fought the urge to adjust his glasses again. "Everyone, with me, to the shop, now. Prompto, lead the way. We can shower when we get back."

It was still odd watching Prompto and Noctis walk ahead of them in Gladio and Ignis' bodies respectfully. Though Ignis certainly wasn't begrudging the view. Gladio's leather pants always did show off his toned ass just so- Ignis shook his head. Shit. He pulled his phone out and started searching the word on the bottle. His Latin was a bit rusty, but if what was stirring in his core was any indication they were all in a lot of trouble.

When the search on his phone confirmed his suspicions, he groaned.

"What's wrong?" Gladio asked as he walked along beside him. "Other than the obvious I mean."

Ignis only handed the phone to Glaido. When he read it he looked quizzically back to Ignis. "Why are you looking up the Latin word for 'lust'?"

"Because," said Ignis, "It's what that pink potion was labeled as."

The color might have drained from Gladio's freckled face if it wasn't already beat red. "Well, that explains a few things." Ignis watched as Gladio subtly adjusted himself in his leopard print pants. "I got a nose full of that stuff."

"As did I." Ignis swallowed hard and tried his best not to focus on the fact that he was almost as aroused as the man standing next to him. He took a deep breath. "Hopefully the shop owner has some answers."

They found Tatianna's Mirror down a narrow, cockeyed street and for a moment Ignis wondered why on Eos Prompto would walk into such a place. He would have to inquire later.

The shop's owner was busying herself with some jars of herbs behind the counter, but perked up when she saw them walk in. Prompto walked up to the counter first, though he already seemed put off by her leering at him. "Well, hello there tall dark and handsome." She cooed and Ignis felt Gladio shutter uncomfortably next to him. It was his body she was undressing with her eyes after all. "What can I do you for?"

Prompto scratched the back of his head. "Umm… yeah I was in here yesterday." He tilted his head, so she'd look at the blonde behind him. "That potion you sold me. The Poly Juice one. Ummm…" he laughed nervously. "How long does it last?"

She looked from one party to the other before her mouth widened in a Cheshire grin. "Oh, how entertaining is this?"

"Not very." Ignis said, ruefully.

Gladio grumbled in agreement.

"Well, it's difficult to say how long it will last," she said. "That one was a particularly potent one, but it's been on the shelf for quite a while." She put a gnarly finger to her chin in thought for a moment. "If it were shared between all four of you, then it should only last a few days. Maybe less."

All four of them groaned in unison. Ignis personally was hoping for only a few hours. Looks like they were going to be using Prompto's credit card for a few extra nights at the hotel after all. Ignis walked up to the counter and placed the remains of the broken vial in the napkin on the counter. "And this potion? Do you have an antidote for it?" He could already feel the heat radiating off Prompto as he stood next to him. A quick glance up showed a blush already creeping across tan skin. If Prompto was feeling anything like Ignis he was surprised the young man was maintaining his composure as well as he was.

The clerk opened the cloth napkin. Upon seeing the label her grin only got wider. "Oh this is one of my son, Puck's potions. Quite potent, indeed." She scanned the four of them and gave each of them a lecherous once over before wrapping the vial back up and handing it back to Ignis. "Alas, there is no antidote other than letting the potion run its course. Unless acted upon, the effects only grow stronger with time."

Ignis' stomach dropped. He kept his gaze straight as he gathered up the napkin, refusing to make eye contact with Gladio who was the only one who knew full well what the label on the bottle meant. The strategist cleared his throat. "Thank you for your time, Madam," he said before turning on his heel and walking briskly out of the building.

"Oh, any time, Honey," she cooed as the door closed behind him.

Ignis was half a block away when Gladio and the others caught up to him. "What did she mean, 'unless acted upon'?" the shield asked.

Noctis flanked him, a concerned look crossing his flushed bespeckled face. "What was that second potion?"

Prompto grumbled another apology. Followed by something about how Gladio could wear leather pants when it was so damned hot out. Ignis inferred that it had little to do with the actual temperature of the air, considering it was still only mid-morning and comparatively cool out for Lestallum.

Ignis took a deep breath and turned to Gladio. "I believe it means exactly what you suspect it does." He swallowed hard and tried to ignore the hungry look the blonde shield was giving him. "But I think we're stronger than that. Let's just get back to the hotel and get cleaned up. We'll figure the rest out there."

Thankfully, nobody asked any more questions until they were safely back in the hotel room. As a last-minute thought Ignis threw the 'do not disturb' sign on the door before closing and locking it. Whatever happened, it wouldn't do to have the cleaning crew barging in.

Prompto was already half way into his room. "I'm gonna take a shower. Gladio, do you have a clean change of clothes?"

Gladio just tossed Prompto his gym bag. "You might as well take the whole thing."

"Thanks," he said before disappearing into the bedroom.

Ignis and Gladio sat down on the couch and watched Noctis pace around and fidget with the collar of his shirt. "Are you alright, Noct?" Ignis asked.

He chewed on his thumbnail, a habit he'd had since he was a child. "Not really. I mean, I am wearing an Ignis meat-suit." He gestured to himself. "And on top of that I'm really fucking horny, if you absolutely need to know."

Gladio chuckled, shrank apologetically when Ignis shot him a glare. "Sorry, that just sounded funny coming from your mouth."

Noctis didn't seem to hear him. "I mean, I'm not stupid so I can guess what that potion that smelled like the harbor does. I want to take care of it, but…" he gestured to himself again, "…this isn't exactly my own equipment."

Ignis took a deep, calming breath and tried his best to ignore his own discomfort of the situation. "Noct, while I do appreciate your prudence with my form, I believe that desperate times call for desperate measures. You may do whatever you have to in order to make yourself feel better." Noctis shot him a blatantly surprised and partially relieved look. "Just…don't make too much of a mess."

Noctis bit his lip. "You're sure?"

Ignis nodded.

Noct let out a keening sigh before turning and heading to the other bedroom in a hurry. "Same goes for you Specks. Whatever you gotta do." The bedroom door closed behind him.

The shield turned to Ignis with a wolfish grin that screamed Gladio, no matter what form he was in. "That was nice of you."

Ignis took another long breath. His composure was fraying more with every passing second, and the fact that Gladio shifted so that his knee was touching his own wasn't helping. He cleared his throat. "At least His Highness asked permission. I'm curious to think what the young Mr. Argentum is doing to your avatar at the moment."

Gladio bit his lip and let out a moan. If Ignis didn't know better he'd say his pupils dilated further. "Gods I hope it's good. I'm sure he won't complain about the equipment."

Ignis eye's widened. "You don't mind?"

He shook his head. "Hell no. To be honest, I'm a little bit of a narcissist, and the thought of someone enjoying my body as much as I do is a turn on." Gladio inched closer to Ignis. So close in fact that he could count each flushed freckle that crossed his cheeks. "So… that leaves us to take care of our little 'issue'. What do you say, Iggy? Wanna mess around like we used to?"

Part of Ignis, the logical part, was telling him that this was inappropriate. That he was currently borrowing the Prince of Lucis' body and that…that…Gladio's lips were on his.

Meanwhile…

Prompto could not take his eyes off Gladio's body in the mirror. He'd seen his upper torso plenty, but he'd used his imagination more than once when picturing what lay beneath those spectacular leather pants. But…holy shit.

First of all, Prompto felt stronger physically than he ever had in his life. He shamelessly flexed in front of the mirror naked a few times before the only thing he was staring at was the heavy member hanging between his legs. Prompto was a little guy, but he was a fan of big cocks, and Gladio had the biggest dick he'd ever seen.

Once the hot shower had completely fogged up the mirror, Prompto decided to finally get under the water. He lathered up with the soap the hotel provided and wasted no time before wrapping his hand around that gorgeous member. Using the soapy water as lube he gave himself a few long strokes, savoring the new sensation. Somehow he'd imagined it would feel like it did with his own, but he was finding that it had its own flavor.

Different strokes for different folks, he guessed.

Part of him felt bad for this, but it was a very little part. Especially as his hand worked faster. Prompto traced the other hand along Gladio's broad chest and nearly gasped when his fingers traced along the nipples. Holy shit they were sensitive. How the hell did the big guy walk around with these out all the time? He alternated attention between the two as he stroked himself to completion in record time, spilling his orgasm all over the marble tile wall.

Once the high had passed and the water had washed the evidence away Prompto took a moment to compose himself before finding the small bottle of provided shampoo. As he washed the grit from his hair he couldn't help letting his thoughts wander to what it would feel like to have Gladio's member in his mouth once they switched back to their original bodies. To have him spread him open and fuck him so hard he'd pass out. Prompto had some toys at home that were as long or wide as Gladio, but not both. He bit his lip thinking about it as the cock between his legs twitched at the thought.

He debated going for round two with himself before thinking that maybe someone else would want to use the shower. Rinsing the shampoo out of his hair he stepped out of the shower, dried off, and threw on a gray pair of Gladio's workout pants.

He poked through Gladio's spit kit and grinned when he found some Gold XL condoms and lube alongside the toothpaste. Making a mental note of it for later he quickly brushed his teeth and filled the coffee mug he'd brought in there with him with water before grabbing the gym bag and heading back out to the main room.

"The shower's free if anyone else wants to-" Prompto froze, eyes wide and mouth agape. Ignis was lounged back along one armrest with the black t-shirt pulled most of the way up his torso. His cargo pants had been pulled down just enough to allow Gladio access to his aching cock. The cock that happened to be completely down Gladio's throat as Ignis grabbed hold of a fist full of blonde hair.

When his best friend's eyes turned toward him there was only the briefest moment of shock before he let out a moan and came.

The ceramic cup in Prompto's hand shattered in his grip.

His own violet-blue eyes turned toward him as Gladio swallowed and glanced down to the renewed erection in the gray workout pants. He grinned and tilted his head towards the second bedroom. "I think Princess might need a hand or two, if you're interested."

Bag still under his arm, Prompto nearly sprinted into the second bedroom.
