"Um... s-so I, I can explain," Reina stammered, slipping the strings of her chemise off her shoulders so the garment could whisper its way down her pale, petite body before sitting down on the end of Kerri's bed with one foot on the bedspread and the other on the floor. Kerri blinked sleep out of her jade green eyes, her drowsy brain still trying to figure out whether she was seeing a dream or reality as her roommate spread her slick and pouty labia apart before sliding two fingers into her clearly aroused pussy. Kerri had never had a dream like this... but she'd never experienced anything like it in reality before, either.

"See, I was... I was talking to Clarissa," Reina mumbled, her blue eyes glassy and distant as she stared vacantly at Kerri and allowed her fingers to piston in and out in a steady, mechanical rhythm. "And she, uhh... she's into all that metaphysics stuff, y'know... she was talking to me about, um, like, quantum mechanics and all that? And she, uh, she was trying to explain to me about the, the observer effect." Kerri slid herself up into a seated position, brushing her auburn hair out of her face and paying closer attention as wakefulness slowly seeped into her mind and she realized what was happening was real. Bizarre, perhaps, as well as inexplicable and completely outside of Reina's normal behavior, but real.

"She... nhhhh... she told me, um, like, if you go, uhh, all quantum? Then, like, just looking at something, um, changes it. Like, I guess when you're not looking at it, it doesn't happen? I. I didn't really get it at first, but she, uhh... she kept talking and I guess I kind of wrapped my head around it eventually?" It didn't even sound like Reina. Usually the willowy blonde was the first to show off her intellect and erudition, overcompensating for a lifetime of jokes about her hair color with a stubborn insistence on proving her immediate mastery of any topic great or small, but this Reina....

She sounded stoned. She was slurring her words, trailing off into odd and unexpected silences as her brain simply sputtered out into absent-minded lust, and Kerri could see a tiny trickle of drool gathering at the corner of her slack and vacant mouth. "I. Um. Clarissa explained it better," Reina muttered, her eyes glazing over yet again as her focus drifted down between her thighs to the fingers lazily pumping away inside her cunt. Kerri didn't have much experience watching another woman masturbate, but she couldn't deny that the spectacle was more distracting than she would have anticipated.

Not that Kerri thought of her roommate that way--not that she thought of any woman that way--but it was really hard to ignore the sight of those two fingers going in and out, in and out, accompanied by the soft squishing sounds between Reina's thighs and her strained, sleepy breathing. "She... it was, um, it was kind of a lot, it was, but she... she told me nothing really happens without an observer. So, like, if you, uhh, if you think about this, like... cat? It's not really alive unless we're looking at it. Or, uh, s-something like that." Kerri couldn't help being quietly astonished by the way her usually brilliant roommate rambled on in stupefied confusion. Was she sleepwalking? Sleeptalking? Sleepmasturbating? It didn't seem possible but Kerri had no other explanations.

"S-so, um... nhhhh... so if what you look at, um, becomes reality, then, like, uhhh... looking at something changes its reality?" Reina's brow furrowed for a moment, as if she was coming up on a topic so perplexing that her gossamer-thin understanding stretched to its very limits just attempting to comprehend it, and for a moment Kerri wondered if her friend wasn't about to snap out of her bizarre masturbatory fugue. But just as she was attempting to come up with an explanation for what Reina was doing naked in her room and why she hadn't woken her sooner, Reina's eyes rolled back in her head until only the whites showed and her face went completely slack for a long moment.

When her gaze refocused, she somehow looked even more stupefied and vacant, and Kerri could see a trickle of drool dribbling down her chin to land on her smooth alabaster thigh. "Yes. That's right," she murmured, sounding for a moment like she was reading from a script. "Watching something changes it. That's the observer effect. When you're... when you're observed, it changes you." That didn't sound right from Kerri's limited understanding of quantum mechanics, but then she was a film studies major. Clarissa could have said that quantum mechanics were the little men who lived inside the atoms and fixed them when they broke, and Kerri would have very little ground to challenge her on it.

"S-so... unnnhhh... so if I... um, s-so, so Clarissa says, um, if I... if I'm doing something by myself, it doesn't... doesn't, uhm, count? Because, like, I'm not being w-watched. She says I have to be watched to, uhm, to make it all, uhhhh... real." Reina's fingers were pumping a little faster now, her pussy lips flushed and swollen as she jilled off with such a ferocious intensity that Kerri's own cunt ached in sympathy just watching it. It occurred to Kerri that she'd been watching her roommate masturbate for quite some time now, staring in sleepy confusion until it had almost stopped occurring to her that what she was watching was in any way odd, and for a moment Kerri almost thought about waking Reina up and shooing her out of the room so they could both get some sleep.

But the notion remained just out of reach, always something Kerri was about to do and not something she was doing right now. It could wait a little longer. She could keep watching. She could keep listening. There was always time to stop it later.

"She showed me," Reina blurted out, breaking into a longer-than-usual silence that had filled up Kerri's sleepy head with the rhythmic sound of that endlessly squishing cunt. "She, I... I was really, I guess I was really confused by then? So she, um, she showed me how it... it changed me when she watched me. I, my head was all, um, all fuzzy, and Clarissa told me it was because she was looking at me as someone who was--was all, uhh, sleepy and dumb and guh, guh, gullible? And because that's how she saw me, that... that's what I became. It, I, she was observing an object, and it was changing it. Changing me." Reina's gaze looked almost impossibly distant now, as though she wasn't even seeing the room around her anymore.

"She, uh... she saw me as her horny little slut?" Kerri noticed Reina's pussy lips twitching and tightening around her fingers, as though the very conceptualization of herself as an object to be shaped and molded by others made her so incredibly wet that she simply had to cum right that instant. "And I, and, and I, ohhh fuck, Kerr, I came s-so fucking hard--" That was the end of speech for another long moment, as Reina's eyes rolled back in her head once more and her mouth opened in a wide, silent howl of pure ecstasy. Kerri could hear the choking sputter of the other woman's throat closing up to avoid a scream of lust that would wake the entire building. She'd never seen anyone climax that hard before, and a sympathetic shudder of bliss ran through her body at the sight. Kerri wasn't into women, but this was a sexuality so raw and potent that it transcended orientation and genre and became a pure animalistic aphrodisiac.

By the time Reina snapped out of her momentary paralysis, Kerri was rubbing furtively under the covers right along with her. She felt a brief spasm of guilt at using her friend's body for porn, but it was quickly overcome by arousal and soon Kerri stopped even questioning why she was staring at Reina's pistoning fingers and slick, messy cunt. It was hot, that was all. It was the hottest thing she'd ever fucking seen and she wanted to get off to it.

"And, um, uh, so, uhhhhhhh... yeah. That's why I came in here." Reina's gaze was slightly more focused now, staring at Kerri's chest through her thin cotton t-shirt in a way that felt almost like she could see past the covers to what Kerri was doing with her cunt. The knowing look embarrassed Kerri, but at the same time it made her pussy surge with an almost feverish heat that she could neither resist nor control. She was so horny it took her almost a full minute to actually think her way through Reina's slurred and mumbled words and realize they didn't make any sense.

But before she could say anything... and almost before it finally occurred to her that she'd become a completely passive participant in this conversation, listening uncritically to everything she was told without contributing a single thought of her own... Reina interrupted Kerri's question unspoken. "Because I... I'm a slut now," Reina gabbled, her fingers continuing to thrust with a rhythm so enticing that Kerri found her own matching them perfectly. "I'm, I'm s-so horny all the time, and, but, ummm... I can't cum. Not unless someone watches me. That's, um, like, the observer effect. If I'm not seen, it, uhh, it doesn't happen." That shouldn't have made sense at all to Kerri, but the throb between her thighs neatly bridged the gap between real-world logic and the verbal picture Reina was painting.

"Clarissa, she's... she's been real nice, she, um, she's been letting me... hhhhhhhh... letting me call her every night and show her my pussy so I can c-c-cummmm...." Reina's eyelids fluttered again, her head lolling forward as the words nearly drove her to another climax, but she snapped out of it to focus on Kerri after only a moment. "But tonight she texted me and told me I... I'd have to find someone else. She said you could watch me cum, Kerr... and, and when I observed you, I'd make you a slut like me. That makes sense to you, right? You're watching me watch you and it's making you horny too?" A chill ran down Kerri's spine as she realized what was happening to her... but it wasn't enough to freeze her rubbing, thrusting fingers in the act.

Because it was making her horny. No matter how hard Kerri tried to deny any actual attraction, no matter how much she refused the bizarre and incoherent explanation Reina provided for the evening's unexpected events, she had to admit that Reina was just so damn sexy with her legs spread and her fingers pumping away inside her wet pussy. And she was going right along with it. And Kerri's enticing, encouraging stare only made her want to fuck herself even harder. Kerri's head bobbed up and down in a slow, vacant nod as her jaw slackened and her mind relaxed into fuzzy tranquility.

It slowly, sluggishly occurred to her that there was one thing she needed to do before she could fully enjoy the haze of masturbatory bliss she'd fallen into, one last action she needed to take before she could let her mind coast to a half and simply jill off in time to Reina's relentless finger-banging. "That's it," Reina cooed, watching all the more intently as Kerri slid her covers away to expose the rest of her suntanned body, then wriggled out of her clothes to expose her lush breasts and lightly furred cunt. "Now... now we can watch each other a-and be good girls. Good girls for Clarissa."

Kerri hadn't really thought about that before, she hadn't put Clarissa's role in all this into focus... but the more she stared and fingered herself, the more she realized Reina was right. This was all Clarissa's doing, it was all Clarissa's observations that were making the two of them so weak and horny and obedient. So naturally they were becoming sluts for Clarissa. The more they masturbated for each other, the more they reinforced their devotion to her. Just like a g-gullible, a g-g-gullible fucktoy should be--Kerry's eyes rolled back in her head as she had her first climax, but in her mind she still saw Reina's beautiful, mesmerizing cunt.

At some point the door to the bedroom opened again, and someone came inside and began speaking to both women in a low, soothing voice. But by then Kerri only had eyes for Reina. And Reina only had eyes for her.

THE END
