"You really thought through everything," Amelia said while examining one of the backpacks I had filled in preparation for Expedition Amelia. She flopped back onto the bed in the smallish hotel room we had rented, and kicked her legs idly up and down. Her tender thighs glimmered with moistness from the shower she had just taken. The towel wrapped around her was just barely enough to conceal her indecent parts, for now.
 
I took a seat next to her, placing my hand on hers and intertwining our fingers. "I could hardly think of anything else. I hope Amy and her mystery date get here, soon, though. Otherwise I might have to start the operation solo." We squeezed each others fingers playfully as we waited.
 
"You just don't have any patience, do you? Well, not that I do either." She laughed. "Although, you're probably feeling more starved for action right now than I am."
 
My gaze strayed unwittingly from Amelia's slight cleavage further down, to where the towel covered her slim belly. "How's he doing?"
 
"He's asleep right now. That probably won't last for long once we get started."
 
Before I could reply, there was a rap at the door, followed by two more. "That must be them now. I'll go let them in." I stood up and went to open the room door.
 
"Room service." Amy's cheerful voice greeted me as I cracked the door open. She was holding a fancy-looking bottle of champagne, and wearing an elaborate outfit with loads of black lace.
 
"Are you sure you've come to the right place?" I teased, while opening the door to let her in, but then I froze when I saw the person standing behind her.
 
"Hi," said April, with a bit of a strained smile and a tiny wave.
 
"You've gotta be kidding me. YOU are Amy's new girlfriend? "
 
Taking April by the hand, Amy forced her way in past me, and shut the door before I could obstruct it. She set the bottle down on the table and then promptly knelt down facing me, hands pursed together. "I'm sorry! I should've told you sooner, but I couldn't bring myself to mention it. Yes, April is my new girlfriend. We've been going out for a couple months now." Her frills flopped plaintively with her bowing head.
 
I wasn't angry so much as dumbfounded. "How did this happen?"
 
"Well, you know how we've always had similar taste in girls?" She looked at me with a pleading expression.
 
I looked back at April, standing sort of bashfully behind Amy, aware that her mere presence was extremely awkward not just for me, but for Amelia as well. That was a little different from the April I remembered, who was usually self-confident to a fault. But I had to admit, Amy kind of had me there. Do you remember how I had said Amelia was probably the second-most-attractive girl in school? Well, much as I hadn't wanted to admit it at the time, the number one on that list was undoubtedly April. Her blonde hair waved glamorously around mesmerizing emerald eyes, and the generously-cut cocktail dress she wore emphasized a voluptous figure which would be any woman's envy. She looked every bit the young starlet from a moving picture.
 
"And what about you?" I said. "Since when are you even into girls?"
 
She rested a hand resassuringly on Amy's shoulder. "What can I say? I was kind of confused for a while after we... you know. And then she appeared, and, well... your sister has a way with women. It's like she knows me better than I do."
 
I didn't know what to say. I looked over at Amelia, who was sitting up on the bed, still wrapped in just a towel. When in doubt, I figured I would defer to her. "Are you OK with this?"
 
"You've already told her my secret, haven't you?" she asked Amy. Amy nodded hesitantly. "And you're not afraid or disgusted or something?" she asked April.
 
April waited a few seconds before responding. "I won't deny I find the concept a little frightening. But on the other hand, Amy was so ecstatic about the whole thing. I think I can learn to accept it for her sake."
 
This time it was Amelia's turn to pause and think for a few seconds before saying anything. "Well then, far be it from me to refuse a chance to make new friends. I trust Amy, and I trust Ace. I'm willing to share a little with them. Let's make this expedition a success."
 
"Amen," said Amy, who simultaneously popped the cork on her bottle and shed several layers of black frills. I don't know she managed to be so fast, but in a moment's time, she had distributed cups of bubbly and stripped down to her underwear.
 
"Where'd you get this?" Amelia asked, sipping from her cup gingerly.
 
"My parents gave it to me. They said to pop it open around the campfire and enjoy our camping trip to the fullest," April explained, herself following Amy's lead a little more restrainedly and removing her shoes.
 
"Some parents," I said, and took a sip of my own. "Looking back, I guess they were always like that."
 
"A toast! To Amelia's new friends, and our adventures inside of her." Amy held up her glass in celebration.
 
"Cheers!"
 
* * *
 
It wasn't long before we'd had our fill of drink (I wasn't much of a champagne man to begin with) and the critically awkward moment came. Nobody seemed to want to be first to get on with things, especially with April only sort of knowing what we were about to embark on, and Amelia's shyness around her. It was completely unlike the aggressive attitude she'd come on to me with. Here we were, wearing on average a fair bit less than decent (myself in nothing but pajama pants), yet we were sitting around kind of idly chatting while postponing the main event.
 
"So I was thinking," I finally proposed, "We've been calling this a camping trip. So let's play a game like we really were camping."
 
"A game?" Amelia looked quizzical. Amy looked intrigued.
 
"Yeah." I grabbed one of the backpacks full of supplies and began emptying it, placing things all around the room. "Kind of like a scavenger hunt, but instead of trying to find an object, we're trying to figure out what's missing. We all close our eyes, while Amelia secretly takes one of these supplies and puts it inside her. Then she tells us to look around. The first one to figure out what's missing gets a point. I guess we can play first to five points or something."
 
"And what does the winner get?"
 
"Hmm... How about, they decide who starts the expedition first?"
 
"Shouldn't that be Amelia's decision?" April politely interjected.
 
"I'm fine with this," Amelia said, grinning slightly. "In fact, it sounds kind of exciting."
 
"Alright then. Round one! Everyone take a good look around, then close their eyes."
 
The three of us took various positions sitting around the small room, while Amelia sat up and began slowly pacing around the room. At some point she stopped and turned the TV on to a station that was playing music. "This way it'll be harder to tell what it was from the sounds."
 
I nodded, eyes still closed, and waited. Amelia paced closer, and brushed her hand over my bare shoulder affectionately. Finally, she sat back down on the bed. I heard a little bit of heavy breathing from her, and then she informed us we should open our eyes.
 
I exchanged glances with Amelia, who seemed smugly pleased with herself, sitting cross-legged on the bed. Amy and April were already looking around at the objects laid out throughout the small hotel room, presumably comparing them with the catalogues in their memory. I supposed I had a bit of an advantage, having packed the bag in the first place, so I didn't stop myself from checking out the three girls in the room. Amelia's hair was almost dry after her shower, falling loosely over her soft features in a sort of unguarded way, while her posture just barely concealed the vital spot between her legs. Meanwhile, Amy's simple black bra clung tightly to her tanlined chest, little protrusions texturing it in the center, and already a trace of moisture visible in the soft pink panties she wore. Guiltily, I moved my gaze on to April, who was still wearing the cocktail dress she'd come in with. With her hand resting idly on Amy's and her hair clipped so one side hung loosely over her face, the alluring dress nevertheless made her look as lithe and curvaceous as ever, showcasing an ample section of smooth thighs.
 
"Ah! It's the waterproof camera that was on the table over there, isn't it?" Amy finally spouted with confidence.
 
"You got me," Amelia confessed. "Alright, round 2?"
 
"Round 2."
 
"Wait!" Amy added. "First, April, babe, you've got to loosen up a little."
 
"Loosen --" April began to ask, but Amy made herself clear with actions more than words. One hand traced its way up April's arm, cradling her head while Amy leaned in with a kiss that stifled any protests, while her other probed up April's thigh, caressing and then hooking the dress and raising it up. In one smooth motion, barely breaking off the kiss, she had lifted the dress off of her girlfriend and thrown it aside. Only afterwards did I notice she'd also untied the side-fastened panties underneath, which were beginning to slip off. And yet, despite being so handily disrobed, April looked like she had indeed become a bit more comfortable, a little saliva escaping down the side of her chin. Damn, did my sister have a way with women.
 
At this point my arousal was rising to the point where it would be hard to conceal, so I was relieved when Amy declared that was it and we could begin round 2. She sat back down between April and me, and once again we closed our eyes.
 
While sitting back up, Amelia had trouble squeezing past me, so I sat up and leaned back against the nearby wall, eyes still closed. From here, I could hear less of her eventual motions until finally she told us to start searching. This time, I decided to actively participate in the searching, but once again Amy came out on top, quickly recognizing that actually several waterbottles had vanished.
 
The third round, the hiding took the longest. I leaned patiently against the wall for what seemed like several minutes while I faintly heard shuffling and even some poorly-concealed squeals from my girlfriend. I could only imagine what she'd picked to hide this time, but it became immediately clear when I opened my eyes.
 
There were now only three people visibly sitting in the room.
 
"Amy!" my ex shouted in no particular direction.
 
"Bingo," sighed Amelia, no longer wrapped in a towel, her crotch glistening but showing no other signs of having swallowed a person. "And for the record, it was her idea. Hold on, sheeeeeEEEEeeeeEEee--" she paused, her eyes closing in ecstasy momentarily. "She says you're next, April--" barely finishing her sentence before lying back on the bed to writhe with more waves of pleasure. Apparently Amy was working quite a number on her still.
 
I shrugged, no longer able to hide my own boner, and April looked back from me to Amelia, who seemed to be trying a "come-hither" look from the bed. In the meantime, I began re-packing the scattered items, this game clearly over, while watching the situation out of the corner of my eye.
 
April approached hesitantly, not sure where to go or what to do. At some point, Amelia jumped up and pushed her onto her back. In a move reminiscent of the girl who was now inside her, Amelia ripped off April's bra, finally leaving the blonde entirely unclothed herself. She reached for the delicate globes of flesh, caressing and massaging them alternatingly, rubbing her knee against April's (still-familiar) slit, working April and overwhelming her with pleasure until she was exhausted. Amelia, still full of energy and with an even more mischievous glint in her eyes than ever, knelt up and guided April's head toward her waiting pussy. I only mildly regretted not being able to see the expression on April's face as she felt for herself the occurrance which until now had been only known to her through Amy's descriptions.
 
The vaginal lips parted, Amelia's hips seemingly spread apart, and April's head vanished from view. Amelia beamed at me as she ever-so-slowly descended upon April's shoulders, giving her "victim" ample time to feel up past her collarbone to where, instead of her own head, there were only the rippling lips of Amelia's ravenous organ. Those lips soon gorged themselves on April's hands and shoulders, squeezing tight over her ample bust. Amelia let out a satisfied sigh as she made it past Apri's ribcage, and soon her hips were enveloping April's with gusto. The last third of her slurped into April's waiting insides quickly, and finally it was down to me, my raging boner, and my amazing girlfriend.
 
I grabbed the backpacks of supplies and presented them in front of me. "Ready for these?"
 
She slid off the bed, giggling with pleasure and landing on her back. Rather than get up, Amelia simply left her legs in the air, splayed wide. She struggled to string words together between delirious breaths. "Bri- bring it."
 
I dropped the bags into the funnel she had made with her thighs, and they vanished faster than I dared think possible. At this point, Amelia was beyond conversation, so I simply leaned in and lended her some ministrations with my tongue before the familiar squeezing of her thighs tugged me deeper and began that familiar but glorious descent into the pink cavern inside.
 
I toppled through her cervix, exhausted from the anticipation as much as anything, and found that there were not two people waiting for me, but three. A familiar-looking, slightly tanned blond guy of intermediate build and also wearing nothing stood in front of a shocked-looking April and Amy.
 
"Yo."
 
"I thought you were sleeping!" I said to him.
 
"I was. But you four made a hell of a ruckus."
 
April and Amy looked at the newcomer, then back at me, and back at him.
 
"Ummm... I was planning on waiting on this, but... allow me to introduce you to Ace Prime," I said.
 
I suppose I should rewind a bit and explain.
 
* * *
 
"You're not gonna believe what I found in here." My voice trailed off as I finished the sentence because, frankly, I was having a hard time believing it myself. I mean, yeah, I had already been sucked into my girlfriend's vagina more times than I cared to count, not to mention some of the other pretty fantastic stuff I had gone through thus far, but I had certainly not been expecting to come across the half-conscious body of another guy in here.
 
Let alone the half-conscious body of another *myself*.
 
Let it not be said that I do not know what my naked body looks like. Not to be weird or anything, but I do, and the person who was kind of exhaustedly dozing on the fleshy ground of the chamber before me was undoubtedly inhabiting a totally identical body. This was both doubly shocking and somewhat reassuring. My encounters with other people in the world of Amelia's insides thus far were limited to Amy -- sent in to find me -- and an encounter with some older, tough-looking dude that was in all probability a dream anyway. I had assumed Amelia would tell me if there was someone else ahead of me.
 
"Amelia, there's someone who looks exactly like me in here. How is that even possible?"
 
She seemed strangely quiet on the matter. "Really? That's... weird..."
 
My doppleganger on the floor rolled over, his eyes slowly cracking open, then (upon seeing me), shooting wide. "You're..." he mumbled. Then a look of dawning realization colored his face. "So that's how it is."
 
"Might I be so bold as to ask who you are and how you got here?" I prompted my lookalike.
 
He straightened himself up and offered a hand to shake. "I guess you should probably call me Ace Prime. To put things simply... I'm you in about a week from now. Give or take. I'm not exactly sure."
 
I eyed the outstretched hand cautiously. "You're... me from the future?"
 
Ace Prime nodded. "Yeah, pretty much. It's OK, it won't destroy the universe or anything if we touch."
 
"How do you..." I started, then stopped myself. "Oh yeah. You've been through this before."
 
"Yup." I gingerly accepted his handshake. The cavern shook -- Amelia giggling amusedly -- but both of us kept our footing with practiced balance. Something akin to sea legs, I guess.
 
Ace Prime looked up as if to indicate that he was directing his voice to Amelia. "So I don't suppose you'd be willing to explain what's going on?"
 
Amelia giggled again. More sea legs. "I honestly... don't know the details any more than you do."
 
"But you knew about the possibility of this before," I surmised.
 
"A previous, uh, guest, did explain to me that it would happen. He said to keep it from you until it was time. Or should I say you said to keep it from you. Will say? Will have said? I dunno."
 
I felt almost betrayed, less by Amelia than by that other future me. My future self was keeping secrets from my past self. Great. Now that was just confusing.
 
On that note... "You still haven't answered my other question about how you got here," I pointed out to Ace Prime.
 
"I really want to know, too," said Amelia. "I think I of all people have a right."
 
He leaned back with his hands in the air, but with a look on his face that was vaguely... smug? mischievous? "I think it's best if you figure out on your own, both of you. You'll see soon enough."
