"Come in!" you call, knowing that it's normal for Luna to be nude. Whoever's on the other side of the door won't be at all perturbed by that.
The door opens and your sisters, Juniper and Ashley, walk in. "Hey Nick, hey Luna!" Juniper says, taking a moment to eye Luna's curves, as your new memories tell her she often does.
"Hey, you two," you say, briefly hugging both of your sisters. "What brings you around to our little abode?"
"Oh, my only class today was cancelled, prof is sick," Juniper explains.
"And today's my day off," Ashley adds.
"So I figured it was the perfect time to give her a tour of the campus, show her the real good spots before orientation next fall," Juniper finishes.
"And what better way to start than saying hi to my big bro and his smoking-hot girlfriend?" Ashley points out. She'd never been shy about her own attraction to Luna, especially since Luna, in this reality, had always dressed in skimpy outfits and was very openly affectionate with you.
"Hey, you're a looker yourself, you know," Luna says. "Both of you." She, too, had never been hesitant to express her attraction to either of your sisters; heck, you'd possessed both of them more than once when you were last using the ring and enjoyed Luna's company in bed in their bodies--in both the original reality and this new one you'd retroactively created. Not that they remembered any of that.
"What're your schedules looking like today?" Juniper asks. "I could text you where we are whenever your classes end, so we can meet up when you're not in a lecture."
"Not too busy," you say. "We've each got a morning lecture in a little under half an hour, but after that I've got nothing until one."
"I've got two lectures this morning," Luna adds, "and another at two, but I'd love to meet up for lunch and a chat. Maybe we could go to the music school afterwards; they have free daily late-afternoon concerts."
"Concerts?" you ask, turning to Luna. "There's so much to do on campus and you want to go to a concert?"
"Actually, that sounds great," Ashley says. You'd briefly forgotten that your sister had enjoyed band class. "Free concerts? I don't care what sort of music they play; I'm keeping my schedule clear for those once I'm here."
"Well that decides that, then," Juniper says, nodding. She pulls out her phone. "You two should really get to class, though." You look at the time and start. Ten minutes to class.
"See you in an hour, Nick!" Ashley says as your sisters turn to leave.
With their backs turned, Luna nudges her elbow into your side even as you gather up your stuff for the day. "What are you waiting for?" she whispers.
You smile ruefully. It had been so long since you had last used the ring, and you'd been caught up enough chatting with Juniper and Ashley, that you'd forgotten that you could once again possess them. With a brief, grateful smile to your girlfriend, you decorporealize and shoot your essence into both your sisters just as Juniper's hand comes to rest on the doorknob.
"Fuck, thanks for reminding me, babe," you make Ashley say as your two new bodies sit back down on the bed. "Almost missed my chance there. Going to have to remember not just what I can do but that I can do it at all."
"Well good, now what's Juniper's first class?" But there's a slightly pained expression on Luna's face, and you suddenly realize why.
"Actually, she doesn't have classes today," you say. "Or I don't, rather."
Now Luna's brought her hands up to her head. "Nick, what's happening?"
"I think it's harder for you to assimilate your new memories when I change reality since you're not the one with the ring," you say through Ashley. "Maybe explaining it will help. For some reason, in this reality, I'm one person with two bodies. These bodies, to be precise. Even though they were born six years apart."
"For some even more inexplicable reason, both my bodies respond to Nick, but this one also responds to Juniper," you continue from your older sister's body.
"And this one is also named Ashley," you add from your younger sister. "Nobody thinks this is at all weird, though, and not only that, but I've just, for some reason, had these powers on and off for the last few years. Mostly off, though."
Luna's discomfort subsides. "And we started dating around the same time as in the... other reality," she concludes.
"That's about it, yeah. I think the ring doesn't really care to create good rationales for how everyone else sees what it does; it just seems to throw a general nobody-cares blanket over everything."
"So why don't you have classes, then?" Luna asks.
"Because though I have two bodies, I'm still one person. Hence, each of my bodies only needs to take half the classes, which I can focus on simultaneously, which gives me a lot more free time," you explain through your older body.
"Fuck, now I want you to put me in another body, too," Luna says.
"Time enough for that later," you say. "Right now I want to get reacquainted with the female form." No sooner are those words out of Ashley's mouth than your two bodies start groping each other, each with a hand on the other's tit and the other hand on her own pussy.
"I bet that if I'd assimilated my new memories properly, this would've been the first thing you did," Luna jibes, smirking. "You haven't changed a bit. Well, not very much, anyway."
"Hey," you retort through your gasps as sensations that part of you hadn't felt in a few years flood back in, "like you're any different. First thing you did that time I put you in Henry's body was jack his cock."
Luna blushed beet-red. "Well, sure, but you'd been possessing girls left and right before that! Fuck, you were feeling up Ava's body before we fucked that time. Hell, the first person you possessed was me, and you fingered yourself to orgasm for an hour before doing anything else!"
"All right, all right," you say, partly conceding the point. "We're both hot and horny and kinky as fuck. "Now how about getting to class while 'Juniper' shows 'Ashley' around the campus?"
"What, you're not going to make yourself any hotter?" Luna says. "I thought for sure you'd give yourself bigger tits and butts before we left. You know I'd love to watch that happen."
"Oh, he won't have time for that," a rich, sultry voice says from over by the window, even though you'd heard neither it nor the door open. "He's not going to have time for much of anything at all."
Who's intruded into the room?
