My name’s Tilana, and my birth was different from most of yours. That is to say, it wasn’t so much a birth as it was an experiment. It was all part of this thing called Project Gemini, so called because there were actually two of us made at the same time.

You see, there was this facility on Earth that was into a lot of science, technologies and behaviors that violated laws in most countries. I can’t tell you too much about it, because honestly, I don’t know its history – the main facility was destroyed some time ago, but its sister facility picked up and moved to Mars.

Mankind started settling on Mars some years ago, once they discovered how to make domed colonies. Earth is still there, it’s not like they went to Mars because they had nowhere else to go. In fact, Mars is a really expensive place to live, and there aren’t a lot of places you can go. Even the ships that ferry people back and forth are beyond most peoples’ budgets. The wealthy elite are the ones that have homes on Mars.

Anyhow, the sister facility picked a remote spot on Mars and rebuilt there, outside of the laws and regulations of the other colonies.

But that’s all just textbook history, nothing all that interesting. I wanted to tell you a story about myself, not about planets.

“Welcome aboard.”

I studied him for a second before responding. He was a little taller than me, and looked to be pretty average in most aspects. His mirrored sunglasses struck me, though – they really did reflect my image pretty clearly back at me. “Thanks – I’m the new engineer.”

He nodded. “Yes, I know. The one from Project Gemini, right?”

“That’s right. My name’s Tilana.” I extended my hand out in greeting.

He took my hand, giving it a brief, firm shake. “James.”

James struck me as an all-business sort of guy. I had heard he was from the facility that was destroyed back on Earth, but I didn’t see anything all that strange about him. Maybe he was just an employee, though, not an experiment. Even the clothes he wore were pretty simple – a black t-shirt, some dark jeans, black boots, a belt that had his various tools on it.

“So where do you want me to start?”

He turned, walking down the tunnel that led away from the airlock, speaking over his shoulder. “Our video recording went on the fritz a couple days ago, and as far as I can tell, it’s nothing on the hardware end of things.”

I just listened quietly as I followed behind James, my own heeled boots echoing softly off the metal walkway. I looked around the tunnel, noting that it had any number of wires running along the length of it.

“It’s probably a pretty simple thing to troubleshoot from the software standpoint, but you know how it is. Rules and regulations, what I shouldn’t mess with, that sort of thing.”

I nodded, folding my hands behind my back lightly as we arrived to the door at the end of the tunnel. It was made up of a spiral of metal pieces that came together at the center. James touched a small button off to one side, and they slid away from the central point to reveal a small room with a circular counter situated in the middle. I was expecting a receptionist or someone to greet us, but there was no one there. The communication device behind the desk had a button that was blinking silently.

He didn’t seem fazed by the lack of greeting, however, simply moving off to the left side of the room, where another of those spiral doors awaited us. “Basic rundown of important times of day.”

I assumed nothing was out of the ordinary, so I just kept walking behind James, listening politely.

“Breakfast is at 0900 hours, dinner is at 1800 hours. You’ll need to plug in to the main computer every night at 2100 hours to check in and receive updates for the next day’s general tasks.”

I tilted my head to the side. “Plug in?”

James nodded, still talking to me over his shoulder as he walked down a long hallway. A number of doors were off to the sides, each with odd numbers on them. All were closed, all had “Do Not Disturb” signs hanging off the handles. The hallway was strangely silent, though. “It’s all detailed in the report that’s been left in your room.”

To be honest, my initial impressions of the Medea were, well… Unimpressive. Nothing really seemed all that out of the ordinary for the kind of ship it was. That is, until later, when I found the problem in the video recording software.

“That should do it, I think…” I confirmed my choices in the menus that popped up, and was happily greeted with the monitors displaying their images correctly. I smiled to myself. “Oh, yeah, gettin’ it done.”

As I leaned back in my chair, I looked over the various screens. They were almost all surveillance, but I noticed something kind of out of the ordinary. I leaned back forward and examined what I thought I saw.

Almost every private room had people fucking each other. Heterosexual couples, homosexual couples, threesomes, orgies. I didn’t see anyone by themselves, but I couldn’t quite place what was so odd about all the sex. I reached up and touched one video, and the rest of the virtual monitors faded away, the one I had touched becoming full-sized and zooming in some. I frowned a little, narrowing my eyes as I studied the guy and girl going at each other.

“Glad to see you got things working.”

I started a little, looking up to see James walking into the room. He glanced at me – or, I think he did, it was hard to tell where he was looking with those sunglasses in the way – before looking at the monitor. “I think those two are new to ZX7.”

“New to what?”

He folded his arms lightly. “It’s in the report left for you.”

I scratched my head. “Well… Want to be nice and just explain it to me?”

I got a light shrug from him, then, “ZX7 is a drug manufactured specifically for use on board the Medea. The clients and employees use it to make sex better.”

“Sounds like a pretty good drug.”

He turned to me, his tone becoming stern, “Don’t touch the stuff.”

I blinked, leaning back a little. “What does it do?”

James shook his head, glancing at the monitor. “Trust me, it’s highly addictive and it’ll fuck you up.”

“So why do people take it? I mean, what are the desired effects?”

There was a long silence before James turned to leave the video room. “Hard to explain to someone who hasn’t done it. It’s not worth it. Don’t ever let me catch you even thinking about taking it. I mean it.” With that, he walked out.

I just kind of stared after him for a moment, really surprised at his reaction. I sort of expected him to be… Well, kind of monotone about everything, like nothing would be a big deal. I looked back at the couple on the monitor. The girl was on her knees, sucking the guy’s cock while she fervently fingered herself.

I wondered what the two of them were feeling. I tried to imagine what it would be like to be on the drug – I mean, sex already felt pretty good, how much better could it be? I leaned back in my chair, watching the expression on the guy’s face. His hand was on the back of the girl’s head, but his eyes were closed and I couldn’t really tell he was on anything. He did seem sort of absorbed in the moment, he wasn’t saying anything.

The girl, on the other hand, looked like she wasn’t getting enough. Her eyes were open, staring up at the guy, and even though she was essentially fucking herself with her hand, she looked like nothing would satiate her. She was bobbing up and down on his cock and working him over like she was starved and cum was the only thing that could slake her thirst.

I glanced over my shoulder at the door. I wondered if it was possible to lock them, but I figured James wouldn’t be coming back any time soon. I slid my jacket off, letting it rest over the back of my chair as I leaned back, really intently watching the girl. I tried to put myself in her position, to really imagine exactly what was going through her mind.

I had never done any drugs before, at least nothing for recreational purposes, so I just sort of let my mind go where it would. Maybe the drug really did make her crave cum. I thought about having a desire to suck off the first guy I ran into, how bad I would want to drop to my knees and rip his pants off. I slowly licked my lips, picturing it very clearly in my mind, my eyes never leaving the expression on the girl’s face.

That wasn’t all, though. She seemed hungry for more. I watched the way she worked her sex over. She didn’t just drive her fingers in and out, she seemed to stroke at just the right spots, spreading her lips open with two fingers, shifting between circular strokes over her clit and slipping her other three fingers back and forth. I slowly reached up and started to trace my fingers down my shirt, playing along the buttons that held it together. I wondered how the drug would physically make me feel. Would my breasts feel super-sensitive? Would I be able to give myself an orgasm just by touching them?

Watching the girl and thinking about it, I decided yes. I smiled some at the thought, idly unbuttoning my shirt, slowly from the top down. I swiveled in the chair a little bit as I did, starting to feel kind of playful as I watched the blowjob continue with great gusto. As I started to undo the last button my shirt, the guy suddenly thrust his hips forward, his cock sliding deep into the woman’s throat. The video capture didn’t have any audio, but from the look on the girl’s face at her mouth being filled with cum, I figured she was probably moaning her pleasure pretty loudly.

I wondered if the drug even made the taste of cum something heavenly. I licked my lips again, closing my eyes for a moment as I tried to think of what it might taste like under ZX7’s influence. I let slip a soft, “Mmm…” as I slipped out of my shirt, letting it pile against the back of the chair.

The girl swallowed the gift given to her, then started speaking to the guy. I couldn’t read lips in any way, so I just tried to imagine what she might have been saying. She was still fucking herself pretty vigorously as she did, I wondered if it was even intelligible.

My hands slowly ran up my hips, along my bare waist, then my stomach, until they reached my breasts. I rested my palms over my lacy bra, and tilted my head to the side, wondering what I would say if I were in that position. ”I’m so horny,” I’d think, maybe not even sure what I was saying from being high, ”Please fuck me, I need to be fucked so badly.” I liked the idea, slowly rubbing my palms over my bra.

The girl’s hand left the guy’s cock to go to her breast, but to my surprise, the guy instead reached over and picked her up like she was nothing, tossing her on the bed. I was kind of shocked by it, it seemed so rough, but the girl seemed totally into it. She arched herself up, her hands still buried in her pussy and massaging her breast. She kept saying something to him.

”Yes, throw me around, take me, use me.” I pulled my bra down to rest under my breasts, causing them to press together some, as I started to play with my nipples. I bit my lip and jerked slightly, I was never quite ready for that first touch. I quickly settled into the sensation, though, moaning softly to myself as I watched the man pull the girl down the bed so that her hips were resting at the foot of it, her legs dangling off the edge. He pulled her hand out of her body, tossing it back up towards her, as if discarding something that was in the way. I guess it was, in a way, as he took no time replacing her hand with his lips and tongue.

I flicked my fingers over my nipples as he did, starting to undulate my body the slightest bit. I could feel myself warming, and I glanced over at the door again. I had the feeling I wouldn’t be stopping now, so I just prayed that I wasn’t interrupted. I unbuttoned my pants, then propped my heeled boots up on the display station’s counter. I wondered how getting eaten out would feel while on ZX7. I was getting pretty curious about what it did, but I couldn’t come up with anything other than it just felt like sex, but more amplified.

Still, the expression on the girl’s face was such ecstacy that I couldn’t help picturing myself in her position again, one of my hands finding its way down to my slit, slipping underneath the lace panties. As she started to buck against the man’s mouth, he reached up and pushed her hips down against the bed, forcing her to stay somewhat still and endure his tongue. I say somewhat because she was otherwise still squirming quite a bit.

I found myself squirming a little in the chair, as well, as I started to stroke at my lips, getting my finger wet with my juices. I pinched my nipple between two fingers, letting out a little cry at the pleasure it elicited, before returning to massaging my breast. I wondered at the frustration I would be in if I was so desperate for release, but unable to move against that tongue. I slipped my fingers past my lips to find my clit, letting out a long moan as I started to slowly rub it.

I could see the girl was starting to gasp, and knew it wouldn’t be long before she’d probably be screaming out in pleasure. I closed my eyes, leaning my head back, imagining the situation. ”Oh yes, right there!” As I thought that, I found just the perfect spot to stroke, finding myself whispering the same phrase out loud. ”Yes, yes, fuck me with your tongue, eat me, oh God, make me cum…!” I found myself suddenly not wanting to take it so slow, starting to stroke at myself with quick motions, rubbing more firmly at both my clit and my breast.

Opening my eyes, I watched the girl stiffen briefly. She was about to cum, it was apparent even just from the monitor. My eyes glazed over as I found myself connecting with the same feeling, and as I watched her suddenly jerk, her hips bucking wildly against the man’s mouth, my own orgasm found its way throughout my body. As the waves of pleasure pulsed through me, I just let my hands rest where they were, enjoying the feeling as it slowly ebbed away.

Blinking, I could see the girl was still in the throes of her little death – or, I guess, deaths – long after mine was finished. I shook my head, wondering what could possibly be so bad about ZX7 as I started buttoning my pants back up.

“Tilana.”

“Holy hell…!” I cried out, quickly pulling my bra back up and scrambling to get my shirt back on and buttoned up. I looked around quickly. “I’m sorry, I was just-“

I didn’t see anyone there. It wasn’t James’ voice I heard, either. I quickly buttoned my shirt up, and again the voice said, “Tilana.”

My cheeks were flush with embarrassment. Had someone been watching me? I couldn’t believe I had done what I just did, I thought for sure someone would scold me for it. As I put my jacket back on, I tried to figure out where the voice was coming from, but I still couldn’t identify it.

It came a little more insistently the third time. “Tilana.”

I frowned a little, clearing my throat and finishing gathering my exposure. “Um… Yes?”

“It’s 2100 hours, please report to your room to plug in.”
