There is a black screen with the words "Teen Casting Call" written in some comic font. This fades and the shot opens to a view of a girl sitting on the bed in an anonymous hotel room. The picture quality is actually quite good, I note.

"Well well well. You're quite the hot little thing," says a voice just beyond the camera. My skin crawls a little to hear him speaking.

But he isn't kidding either. The girl sitting at the edge of the bed is stunning. Her dark hair cascading over her shoulders. Those bright green eyes shining over her impish grin. Her best feature, arguably, is her long, tanned legs that are on display in a very short pair of cut off shorts, crossed very lady-like in front of her. It's probably the only lady-like thing about this whole scenario, my cynical mind thinks.

"And what is your name?"

"Katelyn," she replies, her girlish voice coming out as half-whisper and half-squeak. It's the first thing she has said and it is a lie. Her real name is Kristy. I know this because she is my girlfriend, and as I watch this interview with her, she is sitting beside me here in my dorm room at the college we both attend. She is visibly nervous and biting her nails, studying my reaction but afraid to say anything.

"Well hello Katelyn. And how old are you?"

"Nineteen."

This is true. She'll be twenty in a few months. We've been dating a little over a year, not that the unseen interviewer probably cares.

"Nineteen," the man repeats, rolling it over his tongue almost as if he can not believe his luck.

"Well Katelyn, why don't you tell me why you're here today then?"

The girl, my girlfriend that is, blushes and out comes a hesitant answer, "To make a movie."

"To make a movie? What kind of movie?"

She blushes even more and says, "A porn movie."

"That's right a porn movie. And this is your first time doing that, right?"

She nods and lets out a nervous laugh. I almost ask a question then but we agreed on a few ground rules when we got into this and asking if this was really the first film she made during her two weeks out in California might be crossing the line.

"So how do you feel?"

"Nervous. Excited," she says, and I have no reason to believe otherwise. The real life counterpart sitting beside me is mirroring her emotions. I know she's worried about my reaction to this. Hell, I'm worried about my reaction.

"Hey that's a sexy little Southern accent you have! So do you have a boyfriend back home?"

She nods in the affirmative.

"Ooh, naughty. And does he know you're here?"

She replies, "No." Again, I look down at her and she shrugs.

I suppose that technically it was the truth. When she answered the personal ad a few months ago we had several long talks prior to her actually leaving. I knew what it meant for her to be going out to California on Spring Break and living in a house doing "modelling jobs" for what was actually obscene amounts of money for two broke-ass college students. We were both dismissive to the idea at first, but over time we realized that the money was just too much for us to pass up. I was sick of breaking my neck doing odd jobs and giving plasma just to get by, and her parents refused to let her work because it might affect her grades, but they didn't give her much in the way of living expenses to compensate.

So I guess you could say it's partly their fault that their only daughter ended up going into the porn business for a short time. Anyway, it's easy it rationalize things when you're young.

And me, well I consented too. That part wasn't easy. Kristy was only my second girlfriend and she'd had a lot of other boyfriends before we met. This caused me some jealousy and insecurity from time to time. The idea that she might add more to that total and tip the balance in experience even further made me nauseous.

But we were broke, and our grades were suffering along with our burgeoning relationship. We found ourselves arguing about money at times, which was weird considering how young we were.

 So we rationalized, though in hindsight, I remember that she did most of the talking. We (well, technically she) would make some much needed money in a really short time, we could focus on our studies more, and in the process we might just discover some new things about ourselves and end up a happier and closer couple.And so it was that Kristy somehow managed to convince me that letting her do a porn movie or two way out on the other side of the country might actually be good for our relationship if we approached it with a healthy attitude.

And as long as we followed the rules, of course.

"Do you like sex Katelyn?"

"Yep."

 "And what's your favorite position."

"Um. Being on top I guess."

"You ever been with another girl?"

"No," she said, with a nervous giggle.

I wondered if that was still true, but the rules are the rules and the only way I'm gonna find out is by waiting until she chooses to show me.

"How about anal sex. Have you ever done that?"

My heart actually lept hearing this one. I know she hasn't let me put it in her ass before, and she told me that one part of her was still virgin even after all the other guys she had dated before me. But did she do it out there with some stranger for money? Or more than one stranger? Oh God...

"No," she said quickly.

"Is that something you'd want to do?"

My breath froze in my lungs.

"I don't know. Maybe. We'll see."

My heart was racing. I bit my tongue to stop from asking the questions I wanted to.

And I didn't notice it at first, but my cock was rock hard.

"Alright. I guess we will. Well how about you take your shirt off for us?"

She dutifully stood up and pulled off the simple blouse she had worn. To my surprise, she was braless underneath. My girlfriend's tits are definitely on the small side, but they are nicely shaped and she has perky, dark little nipples that get bullet-hard when she's excited. Seeing her exposing them to a stranger (and the whole internet, actually) for the first time was very surreal.

"Nice, nice. Those are some cute little titties, Katelyn. Now how about taking off those pants?"

Kristy unbuttoned her shorts and let them fall down her long stems. Underneath she wore a simple black thong.

"Wow, now turn around and show me that ass. Oh man, that's amazing."

No argument here. Next to her legs, my girlfriend's ass was definitely her best feature. For the first time, I saw part of the interviewer as he reached out with his arm and cupped her butt cheeks. Even though I knew this was tame compared to what must be coming, I still felt a jolt of jealousy watching another man maul my girlfriend's body, especially since she seemed more than willing to let him.

"Very nice. Very nice. Now how about those panties now?"

 And just like that, my girlfriend was completely naked in front of this stranger. She had gotten waxed apparently, I guess out in California. There was just a thin strip of black pubic hair visible over her neat little pussy.

"Wow. That looks good enough to eat. Do you like having your pussy eaten Katelyn?"

"Oh yeah."

There was a sudden boldness in her voice that I almost found unnerving. She was horny now. She was looking forward to this. Her face turned to the right, off camera, and she smiled at something, or someone, that I couldn't see.

"Well are you ready to fuck this guy? Maybe we can convince him to eat your pussy for you."

Just like that I was startled to see a man walk in from off camera. He was shirtless and wearing jeans. Because it was just out of frame, I couldn't see the face of the guy who was about to fuck my girlfriend, but his muscular body and the bulge in his pants were apparent, as was the look on her face when she saw him.

Kristy, or "Katelyn" rather, wasted no time in getting down on her knees, unfastening the man's jeans, and reaching in for his cock. I had been dreading this as much as anything and her reaction as it sprang out wounded me a little. Granted, it was by no means some obscenely huge porno cock, but in my girlfriend's tiny hand it still looked gigantic. She promptly sucked it into her mouth and for awhile the room was filled with the slurping sounds of her sloppy blowjob.

I paused the film. The angle showed my naked girlfriend on her knees with half of another man's dick in her mouth. I then looked down at the real thing, sitting next to me with a look of almost fear on her face.

It was at that moment, looking back, that I held the most power in the events as they played out, and she knew it. I could have decided then to tell her I was disappointed, nay, mortified that she had decided to go full on porn, that I couldn't get over the thought of her with this other guy. I could have interrogated her about all of the things she did and, ultimately, we could have ended things right there. It would all come down to how I chose to react to this.

I knew what she was afraid of hearing, and what she desperately needed to hear.

I chose the latter.

"Jesus Kristy, this is really hot," I said.

Her face lit up and she threw her arms around me. Her hips pressed against my erection and her eyes lit up.

"Wow. You really are enjoying this, aren't you?" Her hand cupped my crotch and started to rub me over the fabric of my pants.

I wanted to fuck her so badly. She had been away for two weeks and we had not been intimate since she returned. Because of the rules, you see. That one was her idea, and it actually came up after she got back, rather than before she left like most of the others we had decided on. She said that she didn't want me to be overwhelmed by everything, so to avoid that I was not allowed to look up anything that she might have done myself. Instead, we would watch them together in an order that she chose. A drip-feed of content to let us adjust to it together, rather than a sensory overload that might produce the wrong reaction.

I agreed because it made sense the way she explained it. And because I was so mad with curiosity and confusing lust that I frankly would have agreed to almost anything.

In fact, I pretty much had.

"Hit play," she said. I did so and she quickly undressed, her beautiful naked body the mirror of the one on screen. She unzipped my pants and pulled out my aching prick. She smiled up at me and then wrapped her soft, pink lips around it.

For a brief moment, as wet sucking sounds filled the cramped dorm room, I wondered just how many dicks other than mine had been in that mouth while she was gone away. Her technique had certainly improved it seemed. Lots of practice?, I wondered, with equal parts excitement and nausea. Still, I wasn't going to complain. Her hot wet mouth engulfed my cock and for a moment I thought I was going to cum immediately.

On screen, "Katelyn" found herself being picked up by the big man she was sucking off and then she was thrown on the bed. Her legs were splayed open obscenely and her lover wasted no time pushing his face against her sex and giving her the pussy eating she had been promised earlier. The look on her face was pure ecstasy as he licked her intimate folds.

The man who was lapping my girlfriend's perfect slit had dark hair and deeply tanned skin. He was clean-shaven. He looked like he'd fucked a lot of girls and eaten a lot of pussy before hers. I tried not to imagine just how much.

In my lap back in the dorm, Kristy stopped her blowjob, which was probably for the best as I was surely going to come from the ministrations of her experienced mouth.

"Sit up straight," she told me, and I did so. My dick was was at attention.

"I want to fuck you when he fucks me," She said, matter-of-factly.

On screen, the off-camera voice chimed in, saying, "Okay Katelyn, are you ready to take that dick?"

"Katelyn" was already enjoying the oral attentions of the man between her legs, but she did not hesitate to coo in reply: "Yesss."

As I prepared to watch a stranger fuck my girlfriend for the first (but probably not last) time, her real time counterpart straddled my lap, facing away from me so she could watch the scene herself. On screen, the man put his big cock against the pristine folds of my girlfriend's pussy. And slowly. Pushed. In.

Simultaneously, Kristy's hot, wet box sank down on my cock in real life. The effect was incredible. I thought for a brief moment that she felt a little looser than I remembered, but maybe that was just my fears. Regardless, she gripped me with strong kegel muscles and I was immediately in heaven.

On screen, the man gained momentum and started fucking "Katelyn" really hard. The nervous, innocent sounding little girl from the front of the video was replaced by a screaming, moaning sexual goddess who was getting the daylights pounded out of her.

Had she always liked it this way and never told me? Or was she just caught up in the experience of this new situation? She'd had a lot of boyfriends before me, too. Was she that way with them, and just more shy with me? And why?

 I got a lump in my throat as I saw her tiny hands grip his muscular ass, pulling him in. Demanding more, more.

"Oh, you're fucking me so good!" she gasped, each word coming in a cute squeak between thrusts. For a moment I wasn't sure if it was the video or real life.

Kristy's ass bounced up and down in my lap while her right hand furiously rubbed her clit. I had never seen her this turned on before and wondered what other "new tricks" she had learned on her trip. I hoped I would get to find out, even if the thought scared me as much as it turned me on.

On screen the man now had my girlfriend doggie style, and was slamming his big dick into her. I moved the real life girl to the same position and did the same. The on screen girl screamed so loud that I knew she must have come, and I almost asked for confirmation but decided against it. The camera zoomed in from over the shoulder of the man fucking her, and captured the moment that he put his thumb into the cleft of her ass and pressed it against the star of her asshole. It slid in with ease as the man kept fucking her.

"Put your thumb in my ass," Kristy exclaimed as she bucked her hips into me.

I had never seen her this turned on before. She was reliving the moment with me there. I did as she asked and penetrated her butt hole with my thumb. It slid in easily, lubricate as it was by her freely-flowing juices, but I still wondered: Was it looser than I remembered as well? Was there a video out there somewhere of my girlfriend giving another man her anal virginity?

Oh how I had tried to parlay that into her giving it to me before she left, but she just scoffed and suggested I wouldn't need to worry about it. But maybe those two weeks in the valley had changed her point of view on a lot of things. If that video existed, would I ever see it?

Kristy bucked against me, crying out at the sensations while she watched herself get fucked on the computer screen in front of us. The scene was just so hot and my girlfriend was doing a number on me. I was not going to last much longer and I told her as much.

"Come in my pussy, baby!" she said, which surprised me, and also sent me right over the edge. My aching balls released what felt like a gallon of cum into my girlfriend's vagina.

The guy on screen had slightly better stamina. He was, after all, a professional. "Katelyn" was now on her back by the edge of the bed, legs wrapped around her standing lover as he pounded her with long, deep strokes. Her tiny, tanned feet bounced off of his ass as he plowed into her.

Suddenly the man's body tensed and he spoke for the first time: "Holy shit!"

I didn't understand what was happening at first but when the camera zoomed in while he pulled his cock out of her, it became clear. And as if on cue...

"Dude, you came in her!" said the cameraman. The screen zoomed in as a torrent of sticky, white semen leaked out of "Katelyn's" swollen, red vagina. She had a dazed and completely satisfied look on her face and barely seemed to notice the man's semen running out down to the crack of her ass and pooling on the sheets.

"I couldn't help it man. This chick is fuckin' hot!"

Somehow I felt pride in that, even though he was talking about my girlfriend that he'd just fucked.

"Yeah she is. Well, she was supposed to get a facial but I guess we'll have to pay her extra now for the mess. That's coming out of your paycheck, bro."

There was laughter at this, and even Kristy was grinning between trying to catch her breath. She looked completely worn out. Her on-screen lover had already moved off-camera. I wonder if she ever even knew his name?

After a few moments of the camera lingering on her well-fucked, leaking pussy, Kristy sat up on the bed. Her hair was sex-messy and matted with sweat from exertion.

Finally, the cameraman spoke again. "So, anything you want to say to your boyfriend back home Katelyn?"

That broke the spell and my girlfriend quickly shook her head no. Her arms crossed over her exposed chest involuntarily and for that moment, she was back to being the same girl at the start of the video.

Back in the real world, my cock had softened and fell out of the grip of her real-life pussy. Feeling perverse, I spread her ass cheeks and watched my own jism run out of her. It felt like some kind of cycle was now completed. She was home, and mine once more.

But how much had happened between the beginning and now?

"Nothing huh? Well I don't guess I blame you. Okay, so we'll let you clean up and maybe you'll want to come back again some day. Would you like that?"

The camera panned up to her flushed face. Katelyn managed a weak but eager smile and she nodded in the affirmative. The video lingered on her a moment longer. She waved to the camera and then the screen went black.

Free of my cock, Kristy turned and faced me on the bed. "Well baby," she said with a devilish grin, "what did you think of my first movie?"
