Soma awoke to some unfamiliar sensations. A weight on his chest, a hole where his dick should be, and just an overall softness that he was unused to.

“Why does everything feel so weird?” he groggily asked himself.

It didn’t take long for him to get an answer. As he looked down at the sheets, he remembered the events of last night. His girlfriend of the last five years, Pneuma, had surprised him with skinsuits that could turn them into each other, and they had had some fun with the bedroom with them. He was still wearing the skin of Pneuma, as they had gone to bed together, still wearing them. SoPneuma turned to her side, ready to tell her significant other good morning, yet found her (or him, perhaps she was still wearing her suit too, she thought) missing.

She got up to get ready, assuming that PneuSoma must be somewhere else in the apartment. She walked to the bathroom and tried her best to get ready like a girl would. She brushed her teeth, flossed, washed her face, and brushed her hair. Brushing her hair wasn’t weird, as Soma had long hair, although nowhere near as long a Pneuma’s. It was when she went to take a piss that she realized that this was going to be weird. While she had used her female parts for other functions last night, this was her first time going to the bathroom as a girl. She sat down and felt urine trickle out of her nether regions, a completely different experience than she had ever had before. She had to wipe after pissing, a new concept for her, but otherwise, she found going to the bathroom as a girl not remotely as remarkable as she expected. She forewent makeup, finding herself already pretty enough, and because she didn’t know the first thing about applying it.

After her preparations in the bathroom, SoPneuma got dressed in a simple T-shirt and leggings, not wanting to fool around with some of Pneuma’s more complicated clothing. She stepped out into the main area of the apartment and was hit with the smell of breakfast cooking.

“Good morning, dear! How did you sleep? Good, I hope.” SoPneuma was immediately asked upon stepping out the door.

“Fine, thanks. And you?” she responded.

“Oh, just great! I was pretty tired after last night’s events, so I slept well.”

Standing in the kitchen, cooking some eggs, bacon, and preparing some toast was Pneuma, still dressed in the Soma skin, wearing some of Soma’s clothes that he had left from a previous visit, in case he stayed over. It was a pair of dark grey skinny jeans and a plain maroon T-shirt.

“Well, if you’re doing fine, come take a seat: breakfast is almost ready.” PneuSoma said.

She shuffled over, still a little tired, and took a seat at their table. A minute later, PneuSoma served breakfast: two eggs - scrambled, two pieces of bacon, and a slice of toast with marmalade for each of them.

“Eat up! It’s pretty standard, I know, but I thought it would be nice to eat something before continuing our little adventure. Would you like cheese on your eggs?” he asked as he walked to the fridge.

“No, thanks. But could you get me a glass of orange juice?”

“Oh yeah! Sure, I thought I was forgetting something.”

He returned from the fridge with two glasses of orange juice, and a bag of shredded cheese to put on his own eggs. They began to eat, only talking a little bit, as they were both pretty hungry. Once they were done, SoPneuma asked an important question:

“So… uhh… how long are we going to be each other? I have class tomorrow morning, so that leaves the rest of the day, maximum.”

“Well, I suppose I should tell you; I have more suits than just us. They’re all in my closet, surely you saw the boxes when you got dressed, right?

“Oh, no, I didn’t even notice,” she said, embarrassed. “What are they of? More people we know?”

“No, I figured it’d be fun to be characters we like, from video games. There are also some that I don’t even know what they are. I hope they’re weird.”

“You don’t even know what some of them are?! What?!”

“Well, yeah. That was an option on the website, and I thought it sounded fun. Plus, I wanted some to be a surprise for both of us, so that it’s like a gift for me too. Would you like to get started now, or wait a little bit, and just hang out first?”

SoPneuma chose to hang out. While she was looking forward to this almost as much as PneuSoma, she wanted to have some normal time together.

----------------------------------------------------------------------------------------------------------

They first watched a movie together, snuggling up on the couch. When that was over, they played some Smash Brothers and Mario Kart on Pneuma’s Switch. PneuSoma won almost every match and race, as he was better at action-oriented games. SoPneuma mostly played RPGs, which didn’t help here.

It was now early afternoon, and PneuSoma asked SoPneuma if she’d like to begin messing around with the other suits now. She said yes, and they returned to PneuSoma’s bedroom to have some fun.

“So, I ordered three pairs of suits, totaling to six.” PneuSoma informed SoPneuma. “The first pair was of us, the next one is video game characters we like, and the last one is unknown. The pairs seem to have come in boxes, as I only got three boxes, and the first one I opened contained our suits. I’ll go get the next box, so we can open it.”

He went to his closet to get a box, and returned pretty quickly with one.

“So, let’s see what suits await us!”

He opened the box, and lifted out the suit on top. It was a tall, light-skinned girl, with long blonde hair. With her skin came a revealing white outfit with green and gold highlights. There also was a white thigh-band, with a green and gold design on the front.

“It’s Mythra!” he exclaimed. “I know I’ve never played Xenoblade 2, but you did make me watch the cutscenes with you that one time, and I know how much you love the series, so I thought this would make a nice gift. If they sorted these right, then… yep.”

He pulled out another skin, this time being a short, light-skinned man, with short, spiky brown hair.

“Here’s Rex! They even included his weird-ass clothes.”

He pulled out a blue diver’s suit with puffy legs, which let you see the pants underneath.

“So, who should be who?” he asked.

“Well, I don’t know if I could pull off Mythra’s tsundere attitude, if we’re going to roleplay.” SoPneuma said. “I think it would probably work out best if you be Mythra and I be Rex.”

“Sounds good enough. Here you go.”

He handed her the suit of Rex and his goofy clothing, then began to strip out of his clothes so that he could put on the Mythra suit. He took off his shirt, and shimmied out of his skinny jeans. They got caught on his heels, and he had to hop around a bit while trying to get them off. SoPneuma followed his example, taking off her shirt and leggings until she was in her underwear, and then going a step further to being naked. Once in the nude, PneuSoma pulled the shaven pussy of the suit open wide, and stuck his head in. SoPneuma, who had up to this point only seen entry and exit through the mouth was mildly disturbed by this form of entrance, and stood there a moment to stare. PneuSoma’s head was already within Mythra’s body, so he didn’t notice her stares, and kept going, lowering the body past his shoulders and arms to his chest.

When the suit reached his legs, he ran into some trouble: his legs mostly go forward, while the suit was dangling behind him. After some thinking he came across a solution. It wasn’t a pretty one, but a solution it was nonetheless. He laid down on the bed, his sizeable chest against the sheets and used his arms to stretch the vaginal opening of the suit wide open, then brought it forward. With his legs bent in front, he was able to slowly lower them into the opening. Once they were inside, the suit was able to tighten up around him and turn him into a living, breathing version of Mythra. PneuMythra began to get dressed in Mythra’s outfit, knowing it wouldn’t stay on for long.

SoPneuma didn’t care much about style, and just entered Rex through the mouth once again. Since the mouth is a pretty easy way of entering the suit, she encountered no problems. Becoming Rex inside and out, she began to get dressed, too. Soon, both were dressed and ready to begin having some fun. PneuMythra took the initiative.

“Whoa, Rex! Where is this place? It’s not like any place on Alrest, that’s for sure. It looks, cleaner, maybe? It’s definitely more neat, that’s for sure. And the style of building is similar to that which we saw in, what was that place called again? Oh yeah, Morytha; of course, it all looks a lot less destroyed. *Gasp* do you think we went back in time?!”

She jumped and covered her mouth, causing her rather sizable bust to bounce.

“Oh god, her chest is a lot bigger than mine, this might take a bit to get used to. Anyway, you respond, you’re Rex after all, you’re supposed to lead us through this like the big, strong hero you are, right?”

She gave him a little wink. He tried to come up with something to say.

“We’re really doing this aren’t we? Ugh, okay.”

He puffed up his chest and began to talk.

“No, Mythra, I don’t think we went back in time. Remember when the Nopon Archsage brought us to the Land of Challenge? Maybe this is like that? Of course, I would think more of our companions would be with us, and not just us. Then again, only one of Shulk’s friends came with him to the Land of Challenge, so maybe there are no rules to going across universes anyway.”

He started to get sidetracked, caught on his tangent about how various aspects of the Xenoblade world worked. PneuMythra had to tap him on his shoulder to get his attention.

“Umm, Rex, sorry to interrupt, but do you really think all of that matters? We’re stranded in some unusual building with nobody else in sight, surely we should try to find someone else, right?”

“I suppose so.”

They walked around Pneuma’s apartment, having fun while treating everything as new or novel in some sense. While “looking around” SoRex thought of something.

“Hey, Pneuma, does that suit let you turn into Pyra, or is it just of Mythra?”

“Hmm, I’m not sure. I’ll try to turn into Pyra, although I don’t know how I’d go about doing that.”

She thought really hard about turning into Pyra for a while. Nothing happened. She tried again. Still nothing. After trying for a minute or two, SoRex spoke up.

“Aww it’s fine if you can’t, I just wondered if it was possible.”

“Yeah, it would be cool. Sadly, I don’t think I can do it.”

“Should we head back to your room and keep going?”

“Yeah, sure, that sounds good.”

They returned to Pneuma’s room and began to roleplay once more.

“So, Rex, it seems that we’re stuck here in this house for the time being, with nobody else around.” she said. “What should we do while we wait to get out of here?”

“I’m not really sure.” he said, while inching nearer to her.

“What are you doing? Why are you getting closer?”

“Well, if we’re alone, then we can spend some time together. Wouldn’t that be nice?”

She blushed.

“What, no! It’s not like I wanted that or anything… you… you… idiot!”

He approached her, got on his toes, and planted a kiss on her cheek. Her cheeks went from a light red to deep scarlet.

“Well, I suppose you’re right. We could have… a little fun while we’re here.”

She gave a weak smile. SoRex, seeing his opportunity, tried his hardest to push her onto the bed to cuddle. Sadly, he was too weak to push the heavy blade over. She let out a little laugh.

“Here, let me help you.” she said with mirth.

She lifted him up with ease, and laid him down on the bed. Once she made sure he was adequately comfortable, she laid down next to him. They broke character and began to start their foreplay.

Since they were once more their usual sex, the two lovers were much more in their element than the previous night. SoRex lifted up her skirt and took off her panties, exposing her well groomed slit, slightly wet in anticipation of what was coming. He lifted her clitoral hood, and began to lick circles around her aroused clit, eliciting some soft moaning from her. She reached down to rest her hands on the back of his head, gently pushing him into her nether region. He continued to stimulate her with his tongue, eventually moving lower down to lick the inside of her pussy. He felt her wetness on his tongue, tasting the slightly salty and bitter natural lubrication that her body was emitting. After giving her oral for a few minutes, switching back and forth between her slit and her clit, her breathing became much more labored, and she found herself pressing SoRex’s face quite hard into her genitals.

“I’m… cumming… Ahhnnnnnnnn!”

Unable to move away, SoRex found her juices slowly squirting onto his face, not that he minded, he quite liked it.

When PneuMythra snapped out of her blissful state of orgasm, she apologized to SoRex.

“Sorry, I kinda smashed your face into my crotch, it just felt so good, you know?”

“Ahh, don’t worry, it’s fine.”

“Are you sure? I want to make sure you’re into this as much as I am. Anyway, what now? Should I give you a blowjob, or should we have standard sex, or what?”

“Well, you do have a much larger chest than usual… how about giving me a titjob?”

“Ohh! That’s a great idea! I’ve never really been able to do that with my regular set, and I’ve always been at least a bit interested in trying.”

PneuMythra traded spots with SoRex, letting him sit on the edge of the bed while she knelt on the ground before him, her chest reaching his crotch height. She worked his skin-tight, blue pants down and let his erection flop freely. Once his dick was free from the confines of his pants, she began to give it a gentle lick along its length, while lowering her top so that her large breasts could come into the open. His penis began to get hard, and soon it reached its full length, causing PneuMythra to cease her quick blowjob.

“Is that all there is?” she asked with a stifled laugh. “It’s quite a bit smaller than your regular equipment, Soma.”

He blushed. “Well, I suppose that they makers wanted to have some fun with the sizes, maybe? You would know better than I do, after all you ordered it. Actually, was this your idea?”

“No, I swear I didn’t tell them to make Rex’s dick so small. At least it should make the titjob feel better, since it’ll be swallowed up in them.”

She hefted her chest forward, nestling SoRex’s dick in the crevice between her two large breasts. She then pushed them together, smothering his cock in a pillowy softness that felt sublime. His breaths began to get harder, as he became more aroused. She started to move her tits up and down along the length of his short shaft. This went on for a short while, the rhythm of the movement entrancing both the lovers. After a while, to break up the action, PneuMythra squeezed her breasts to the base of his manhood, allowing the tip of his dick to peek out from the mountains of her chest. She began to give him as good of a blow job as she could considering its length, while also moving her breasts around his dick.

This combination blowjob-titjob was proving to be too much for SoRex to handle, and his tiny penis began to spasm, releasing his cum onto the face and chest of PneuMythra, coating it in white liquid.

It kept going for what felt like an eternity, releasing far more semen than what should seem possible, causing PneuMythra’s face to be dripping in cum.

“Well, that’s fun!” she exclaimed. “Unless you just had a lot left in from you that I didn’t tap into last night, it seems like they can make suits have more sexual stamina than usual. I’d like it if they didn’t surprise us with these features, though. I’ll have to give them some feedback in my next email.”

SoRex couldn’t speak from shock, having just orgasmed for almost a minute straight.

“Do you want to keep going? Or do you want to try out the last set of suits, dear?”

She kissed him on the cheek, bringing him back to his senses.

“Oh, uhh… either really works for me. I must say I am a bit curious on what the last ones are, though.”

“Well then, let’s break them out! We can always have more fun with Rex and Mythra at a later time.”

She walked over to the closet, and pulled out the last box from within. SoRex came over to watch her open it, being almost as excited as she was to see what the surprise suits were.

The tape ripped off, and the box’s flaps were opened to find just one suit and a note.

“To Pneuma and Soma,

Since Pneuma said that it was your anniversary in her order, we decided to send an extra special suit instead of the two suits that she had ordered. While any suit can be worn with multiple people inside, we tailor-made a suit to make the most of having two wearers inside. Please enjoy yourself, and even though we shouldn’t have to say this, you probably shouldn’t wear this one outside.

- Oscar Kaufman, Dermcorp”

She lifted up the suit to see what exactly they had sent and found an insane sight. She was holding the skin of some kind of monster girl, with pitch black eyes, sickly green skin, long, dark blue hair, four arms, and the weirdest set of genitals she had seen.

“What the fuck did they send us?!” she asked, rather amused. “There’s dicks where its nipples should be, and it looks like it not only has a vagina, but two dicks?! They really went all out with this, huh Soma?”

Soma shyly nodded, just staring at the skin she was holding.

“Well, come here, they said both of us should put it on. Now, how will we both get this on? I don’t know if one orifice can stretch far enough to get us both in. I mean, it probably can, after all they said any suit can let multiple people in, but I don’t want to stretch it that much, you know?”

“How about we go in different ways?”

“Great idea, Soma!”

She laid the suit on the ground between them and began to slip into its ass, feet first.

SoRex gave a little sigh and entered through its mouth, awkwardly snaking in as his hands stretched the oral cavity wide open. Despite PneuMythra entering on the other side, he couldn’t see her through the suit, and wondered what kind of technological trickery even went on to make these things work.

They got in the suit, having two large, person-sized bulges on each side. It quickly evened itself out, turning from a lumpy suit on the ground, to a normally proportioned humanoid laying down.

“Whoa, that felt odd, are you okay Soma?” Pneuma asked aloud through the suit.

“Yeah, I’m good, the suit said back.”

“Oh god, this is so weird, I can feel your thoughts and everything, it’s like you’re part of me now.”

“Yeah, it’s… odd? Certainly a new experience. I like it though, it makes us feel more together than usual.”

“Yeah, it’s kinda sweet in a way, inhabiting the same body as your lover. I’m sure staying like this for a very long time would get old, though.”

“For sure. I’m kinda curious about this body. The note said that it was designed to make the most out of two people being inside, I wonder what that means?”

“I’m sure we’ll find out in a second.”

They stood up, finding that they could easily coöperate despite being two minds in one body. They walked over to where the vibrator and dildo had been stashed hastily the night before. The vibrator was switched on and applied to the suit’s clit. It was much harder to reach than expected due to the two dicks right above it, but they were able to maneuver to get it stimulated.

Once they were adequately aroused, the dildo was inserted into their moist pussy; they came immediately from the stimulation.

“What the…? Why did we cum already? Maybe that’s one of the changes they made to the suit? To make it make the most out of two people being inside, I mean.”

“Perhaps, we’d need to try other spots, to make sure.”

They began to use one set of arms to massage their two dicks, finding them cumming far faster than they usually would. They kept going, and came again and again.

“I believe we can say that yes, it does cum faster than usual, but it also seems to have no refractory period at all. Do you know what that means?”

“Oh no, you’ll be stuck in this all day, won’t you, Pneuma?”

“Perhaps, infinite speedy orgasms sounds like a lot of fun to me.”

They quickly tried to clean up the mess they had made, then moved to the bathroom, so that it’d be easier to clean up.

----------------------------------------------------------------------------------------------------------

They sat down in the bathtub, then resumed their activities once more. They reäctivated the vibrator, stimulating their clit constantly once more, then inserted the dildo into their pussy, causing more cum to spill out. They began to ride the dildo, going up and down along its length, feeling a near constant state of orgasm from the frequent stimulation. They went at it like this for a few minutes, just enjoying the feeling of female orgasm. Eventually they decided to add in the penises. Just a short bit of stroking led to them cumming as well; combined with the dildo ramming their pussy and the vibrator stimulating their clitoris, they felt a wonderful fusion of both the male and female side of the sexual experience simultaneously. Their breathing was quite hard from the stimulation of their entire nether regions. Yet, there was still one more thing for them to try out, which was completely new to the both of them: dick nipples. While their other two arms that weren’t in use could stimulate them easily, they chose to give one of the nipples a blowjob, while jerking the other one off, leaving one arm left doing nothing.

Just like everything else, their nipple dick came quite quickly, giving a strange feeling of orgasm in their chest, and filling their mouth with cum. They swallowed and continued fellating their nipple, feeling it cum over and over. The other nipple also came, stimulated by their third hand, and helped contribute to the filling bathtub of cum.

They sought out a use for their free hand and at last came to a conclusion: anal fisting. They took their last hand and shoved it up their ass. With their hand up their ass, they quickly found out that this skin also had a hyper-sensitive prostate, despite being vaguely modeled after a girl.

Using the skin to its fullest, they reached maximum orgasm, basically hyperventilating with arousal and stimulation. This continued on for some time, cumming with their pussy, twin dicks, and dick nipples, while stimulating the inside of their ass.

Eventually they had to stop: the bathtub had begun to overflow with semen. They stepped out, the lower portion of their dark green form coated in the white liquid. They began to drain the bathtub, hoping that their drain system could handle such an onslaught of seminal fluid. They took a handful of their love juice to their face, and drank, enjoying the unusual flavor it had compared to normal. Instead of tasting salty like normal, it had a sweetness to it, tasting not unlike berries.

They went back into the bedroom and laid on the bed, wrapping themselves in their sheets. Despite all of that sexual activity, they weren’t tired, and instead spent their time doing what was, in essence, a one person cuddle.

“I’d say this anniversary present was a success, wouldn’t you?” Pneuma asked Soma in her head.

“Yeah, it would seem so.”
