A brief discussion

"I'm not sure what we should do," you respond in a low voice. "It seems like the aliens want to observe human sexual behavior. Before you woke up, they were showing me pornos so I'd get hard."

"So why don't they just look at the pornos to observe human sexual behavior?" Syndie asks.

You shrug. "Maybe they've got instruments that are going to be measuring things somehow, so they need to see it live."

Syndie whispers, "They're in for a surprise if they think it's going to be like a live-action porno. I mean, I know I've got big boobs, but the rest of me isn't exactly porn star material."

You almost blurt, "That's not true," but then wisely decide to keep your mouth shut. What does happen at this point is a wide beam of light shooting out from the ceiling, wide enough to completely encircle Syndie for a couple of seconds.

Syndie manages to spit out a, "What the hell?" before the beam disappears. Once it does, it becomes clear that she's being transformed. Her skin darkens to an even, golden-brown tan, the freckles sprinkled across her face and chest disappearing. Her triangle of brown pubic hair recedes into the skin, leaving her smooth in that area.

The hair on her head grows out at a furious pace, extending from shoulder length down to just above her ass. A few light brown highlight streaks appear in it.

Her face changes subtly, with her cheekbones pushing a bit higher, her eyes opening wider, and her lips swelling a bit. She's already wearing a bit of makeup, but it enhances and darkens, her eyes rimmed with black and painted with colorful eye shadow, her lips gaining a glossy sheen.

Her waist cinches in a couple of inches and her stomach flattens, but it looks like her tits and ass are being left alone, fortunately. A dangling silver charm appears in her newly-pierced navel, and as you look up, you see a tattoo of a chain of flowers now circles around her left arm near the shoulder.

"Holy shit," she says, and you can see that she has a silver barbell through her tongue, "look at you!"

You were so busy watching her enhancements that you didn't notice your own. You look down at your naked body and see that you've now got the same tanned, smooth skin that she does, and well-defined muscles under the skin. Your arms and thighs look almost twice as big as they used to, and your abs are visible in the form of the 6-pack you've always wanted. Your pubic hair is gone, which makes your straining hard-on even more obvious than before -- in fact, you think it may have gotten larger, because it still seems to be the same size relative to your new body.

"Oh, my God," says Syndie. You look into her deep blue eyes, noticing that her eyelashes have become almost ridiculously long. "I don't think I've ever been this horny before. I think those aliens literally turned us into porn star material." She brings her legs up onto the examining table on which she's seated, and you see that she's wearing black platform sandals with very high heels -- exactly what the woman was wearing in that one porno you were concentrating on the most.

Now that Syndie looks even more like someone straight out of your fantasies, you're even more horny yourself. But now that you know the aliens have this sort of technology, a small part of you wonders what else you might be able to have them do.
