Planting the seed for carpets

In your own room, Casey is still with Teak, who has pinned her in missionary, and seems to take his time slow-plowing her. The tall, tanned guy jumps up as you enter the room unannounced, searches for the non-existant bed-sheets and then grabs one of the plush pillows to hide his manhood. His eyes are searching for the safety of his swimsuit, the official student uniform down here in the bowels of the dorm.

You shake your head and giggle quietly, checking out the room. Ashley is not in, probably still with Carina. You wink at Teak, and smile, already unzipping your own suit again.

"Hey Teak, I didn't want to interrupt anything."

He is still mortified, but Casey grabs his hips and pulls him back down onto her. "You're making a mess out of this, boy! Tzz-tzz, already limp again!"

"H... hey... you said... we had the whole evening..." Teak stammers with an elevated voice, looking down at Casey's prone figure.

"We have, don't we?" you stick a finger into your mouth innocently. "I just had to discuss a group project with Maion and Robert, but it turns out the boys have finished their part earlier than expected. So, of course I had to hurry back to our date now!"

"Our date?" Teak stares at you as if you were a ghost, then back at Casey. You check out his eyes, they are as misty-grey as his hair is. His mutagen is properly triggered already, if you are not mistaken.

You nod eagerly. "Like, our threesome. Casey, didn't you mention that you have roomies to share with?"

Teak now has grabbed his swimsuit and rips himself free from Casey's embrace. Sliding from the slippery bedsheets, he quickly gets into the suit, although he tangles himself up in it and falls onto the thin carpet.

"Ooops." you giggle, and Casey begins to laugh raucously.

Beet-red and humiliated, Teak tears his swimsuit over his shrivelled manhood. Then he gets himself together long enough to assume a stiff posture like a Butler, bows awkwardly and rasps out a "... ladies..." before turning around and vanishing almost quicker than you can follow.

Casey, still lying on the bed, holds her stomach, guffawing. Making sure the door is closed again, you saunter to the bed and kneel on the mattress to look down on her face. "Hey, I mighta joined you two, like, if he don't get spooked."

She grimaces. "Eh. Turns out Teak is energetic and with stamina. Help me comb my hair?"

You nod, pulling her head onto your lap and applying the brush that sits on the nearby vanity. "The way he retreated, the guy seemed totally embarassed. Who doesn't want to fuck two beautiful girls at the same time?"

Casey pouts. "Teak, clearly. Can't shame him, totally a virgin. No fantasy, no technique. There was foreplay, but mostly just squeezing my boobies after I didn't suck him off."

"You didn't suck him at least a bit? He looked like a grower..."

"So what, yes he was. And he was fully grown up right when we started, and he didn't ask." Casey shrugs. "But I'm sure our intercourse worked, and that we triggered his changes. That's all I needed from him, right now."

"Yap." you confirm. "His eyes have changed."

She shakes her head, and you have to hold her still to keep brushing and untangling her hair. "If you say so. I have no flirting idea how you can magically see who was triggered and who wasn't."

"Magic?" You ask. "You said we're, like, from different dimensions. My color-vision is totes not magic."

Casey just grunts. "My explanation was different worlds, not dimensions. You know, the parallel-worlds theory. Where every second, every decision that anyone makes..."

"... creates another world to split off, right." you interject. "But nobody can travel between these worlds, right? So how does this even work?"

Casey sits up and looks straight into your eyes. "I have no flirting idea. But let us compare notes: Is there something different in your world, than what you see right here and now?"

"Wow. Um, like, I'm not sure. Um, until arriving in this dorm, I've never seen a bed that fills up an entire room. Or, you know, most of one." you begin. "This whole bed we're sitting on is pretty insane." You point towards the air slits in the walls, that slowly emit warmed-up air to the contraption, making bedsheets superfluous.

Casey grins, proudly. "Pretty nifty, yes. It's a custom order though, I've seen this thing in a catalogue once and wanted it in my dorm room, too."

"And you just got it installed? How did the college even allow that?"

The grin widens. "I get what I want, Emcey. That's how it happened. And my Daddy paid for it."

"He is rich." you murmur. That matches the original reality, or at least the one reality where you became Casey's coed roommate. "And he owns a big company. I don't think our dimensions... I mean, our worlds are so different."

"Almost." Casey says, hesitantly. "He's just the CEO, but still. But, there are things in my memory that are different. It feels as if the rooms in this dorm should be above ground, you know? I remember sitting in this room and looking out of a window. And having a closet in the room, with all my clothes. It's just a flash, a faint impression. But it feels right... somehow."

You nod. The whole concept of your underground dorm with a swim-training hall is pretty wild. You have no idea why your wish was fulfilled in that crazy way. All you wished for was an indoor pool in the dorm, not a change of the entire dorm setup. But again, you cannot reveal the whole truth. So you answer in a different way. "I mean, sure. Everyone knows how a dormitory should look like, Casey. Like, a big boxy building with three to eight floors, with long hallways, and small rooms cramped full of smelly students who do nothing else but videogames and party." you say. "That IS the image of almost every dorm in the world, right? Well, this swimming dorm is an exception."

Casey bites her lips and lets out a sigh. "Still. A rather strange exception." She pats you on your thigh. "I'm tired. You're doing the big spoon tonight." And that is just how it happens, you realize, as you both shuffle into position on the huge warm bed. Casey always gets what she wants.

It is really comfortable on the bed. You breathe in the smell of Casey's dark-violet shampoo and imagine how it must feel for her to have your large breasts smushed against her back. Your hand slips around and strokes her smooth silky tummy, and then she grabs it and holds it tight. "These parallel worlds..." she says under her breath. "This is really mysterious."

"I remember a thick plushy carpet." you volunteer. "Everywhere in the dorm. Rooms, hallways, dining..."

"You remember that?" Casey asks sharply, but not moving an inch.

"Ehhh. I mispoke. It's more hazy, like a dream." you lie. "But there were carpets." This is planting the seed for tomorrow's change, you feel. You already wished for the carpets, you will totally have them tomorrow. And if Casey remembers that, she will have a deeper mystery. "What I remember more clearly are the swim drills. All my life. Isn't that the reason why the two of us chose a swimming dorm?"

That last part is at least half true. When you wished to be a great swimmer, your entire past has re-arranged to give your the body, muscles and reflexes of a great swimmer. And that included endless swim training, and even a different high school you went through. Thinking about it, you still remember all the other schools of your other realities you grew up in. Until today you believed that no one else could remember the original realities. But what Casey said, makes you a bit nervous.

You originally didn't even like swimming all that much. Now that you can swim like an otter, you love it. What else has changed in your outlook? You grind your pelvis against Casey's bum as you slowly drift into sleep. "Carpetssss...."
