You must run some more tests... for science

Leanne looks up at you expectantly. She has the same expression in her face as Janelle did - one of slight but honest confusion and worry. "Oh dear," she says, "are you okay?"

The glow, or aura - or whatever you want to call it - isn't as obvious as it was the last time, which seems normal given that this room is significantly brighter. Still, it's quite obvious, and it's spreading: at first, it was just in Leanne's mouth, and then it moved down her throat and presumably into her upper stomach as she started swallowing; you can't tell for certain with her clothes on.

By now, you already know better than to admit to seeing weird stuff. However, you do want to find out more. Was this because you came in her, or just because your sperm is always glowing now? Or did she cause it? Will it happen every time? Will she do anything you ask or was it just the blowjob?

You have roughly a million questions you want answered. Of course, you could go back home and jerk off to find out the answer to a few of them... but that's not as fun as the alternative, and besides, it doesn't let you see what you can get away with. So one step at a time seems reasonable.

"I'm fine," you reply, mostly telling the truth. "That was great. It's just... I think I'm still a bit stressed. I want you to take of your panties so I can unleash the rest of my stress in your pussy."

"No...," she goes, "I really don't think I can do that." You start panicking - did you take this too far? What happens now? This could be a disaster, especially since she might know your parents. Then she stands up and hikes up her dark black skirt to her waist using two glowing fingertips. "After all, I'm not wearing any panties."

Leanne's mischieveous smirk and that line is easily all it takes to get you fully prepped and ready for round two. And like apparently every single part of her, everything she's showing off is nothing but exquisitely groomed. She has a gap between her perfectly symmetrical thighs that lets she see how her clean-shaven slit goes all the way below where you can't follow it with your eyes any lone. It's an innie, apparently, slightly puffy, with the surrounding skin looking really smooth and velvety. Just above the clitoris, there's a well-trimmed triangle of black hair - classy, sexy, but not in the way for action.

"So how do you want me, big boy?" Leanne asks. That's a step up from "boy", you think to yourself.

You still have some experimenting to do before you start with... well... your experiment. And besides, you intend to make the most of this - who knows when you'll get this chance again!

"Actually, get those breasts out and come sit on my lap."

"Ooh... I like the sound of that..."

You do want those puppies out in the open, but not just to play with them. In fact, they're the answer to your first question: how far can you trace the glow if her clothing comes off?

It's getting increasingly harder to think about this, though, as Leanne's doing a classy slutty striptease to show off. She only needs to remove a few buttons and a bra, but she manages to draw it out just long enough to aaalmost make you want to do it yourself. Then she climbs on top of you, in heels, puts her arms around your neck and whispers "Which do you want?... I'm wet and tight... here... and I'm clean and experienced... here..."

As she's whispering, she gently gyrates to move the tip of your penis between her holes. She wasn't lying about being wet - what is it about every woman you meet practically dripping to see you? And it's a great question: which one do you want?

But your first priority is still playing naked detective. "Why don't you keep teasing me a bit? I want to play with these while I decide..."

Of course, she eagerly agrees, and you put one orb in each hand. They're phenomenal: large and heavy and soft as silk. No hair, no moles, no blemishes at all. You still can't tell if they're real or if she has a ridiculously good surgeon, though you're leaning towards the former.

As you push them apart, you can see the trail of your sperm by the aura going down all the way to her digestive system. And the glow has started to spread a little to the sides beyond that. You remember how Janelle had looked, and how she was still glowing on tv, and you're guessing it's a gradual effect. Why it took much less time to fully cover Janelle, you don't know - although that was of course in a different orifice.

You take a nipple in your mouth while Leanne expertly moves around without penetration. It's not big, but it's very hard, and almost resists your licking. She rewards you with much heavier breathing, and almost plunges herself down on your waiting member. Seeing how sensitive she is to nipple play, you start a full-on **** on her breasts, squeezing and sucking, pinching and licking across her large areolae.

Then she does something really unexpected. "Please," she says. "I can't take it anymore. I need a cock inside me now."

The ice queen has broken, you think. "But I haven't chosen a hole yet," you tease. By now, though, her entire upper body - head, neck, chest, and stomach - are all glowing, and your little experiment is over. "Bend over that desk and pull your skirt up, and I'll pick one to surprise you."
