Kathrine & Irene have a little chat

Kathrine paces back and forth across her dorm room. She had her face in her hands, red in the face from excitement and embarrassment. She didn’t know what was worse, that she had tried to invite you, her own flesh and blood brother, into her dorm room with impure intentions, or that she had completely whiffed her shot, trying to seduce you by infodumping at you and inviting you to see her ‘textbooks’ as a strong contender for one of the worst euphemisms ever made.

Then she remembered that there was somebody out there who was actually interested in whatever it was that you were doing to her. She thumbed through her phone, bringing up the contact for one Irene Scott.

Irene sits up a little straighter in her office chair that sat dead center of her apartment turned home office as she hears her phone ring. She sighs and puts down a long overdue textbook onto a cluttered desk to answer the call.

"Hello?" she answers, her voice tinged with a hint of annoyance at being disturbed from her studies.

"Hey Irene, it's Kathrine," your sister's voice comes through the tinny phone speaker, sounding flustered and excited. "You won't believe what just happened."

“Oh?” Irene says, fumbling through the piles of reports, research papers, notes, and forgotten empty coffee cups that decorated her desk and surrounding floor space. “Is this about John again?” She asked, reaching for something.

Kathrine nodded, invisible through the phone. “Yeah, it is,” she chuckled, feeling her heart flutter a little even just from the thought of you.

Irene's interest is piqued immediately. She grabs what she was searching for; a notebook, the cover stained with spilled coffee, with her compiled notes on you that she opens to the next blank page, a clipboard, and pen, ready to take notes. "Do tell," she says, her mind already whirring with excitement.

"It was so weird," Kathrine says, her voice rising in pitch as she recalls the events, sitting back against her bed. "We were at the Greasy Spoon for lunch like we always are, and I just―” she sighs deeply. “I couldn't stop thinking about him. It was like my body was on fire, and I just wanted to― to―" She trails off, unable to finish the sentence, increasingly lost in lustful thoughts.

Irene nods, jotting down notes on her clipboard. "Fascinating," she murmurs. "And did you experience any physical symptoms? Shortness of breath, lightheadedness, increased heart rate?"

"All of the above," Kathrine confirms. "And, um, I got really wet, too. Like, almost soaked through my panties wet."

Irene raises an eyebrow, making another note on her clipboard. "Interesting. And how long did these symptoms persist?"

"I―” Kathrine chuckles, idly rubbing her knees together, “they're still going on, actually," Kathrine admits, her voice sheepish. "I can still feel it a bit, even now. It's like I'm in heat or something."

Irene nods, her mind racing with possibilities. "And do you happen know if your brother is sexually active?"

Kathrine hesitates before answering. "I... I don't think so," she says slowly. “At least, I hope not," she mouths.

"I see," Irene says, making another note. "And do you know if, hypothetically speaking, he responds well to monetary compensation for taking part in experiments?"

"I― I don't know," Kathrine admits. "I've never really talked to him about that kind of thing."

"Hmm," Irene muses. "What about sexual compensation? Do you think he'd be more receptive to that instead?"

"Absolutely not!" Kathrine snaps, her voice indignant. "He's my brother, Irene, for heaven's sake!"

"Of course, of course," Irene says quickly, trying to placate her. "I was just exploring all possibilities."

Kathrine sighs, running a hand through her hair. "Look, I just― I really need to figure out what's going on with me. Can you help me with that?"

"Of course," Irene says, her voice soothing. "That's what I'm here for. Now, do you think you could get into your brother's apartment? Maybe swipe a sample of his... well, his semen?"

"Jesus Christ, Irene!" Kathrine exclaims, her voice rising in pitch. "You're asking me to break into my brother's apartment and steal his―” she blows out a deep breath, trying to stay calm, “Are you out of your mind?"

"It would be incredibly helpful for our research," Irene says, her voice calm and measured. "But if you're not comfortable with that, I understand. Perhaps we could find another way to get a sample. Do you know his masturbation habits? How does he dispose of the evidence? A semen sample could prove very useful."

"I― I don't know," Kathrine admits, her voice small. "I've never really thought about those things before."

"Well, do you know if he goes to the gym?" Irene asks, changing tactics. "Perhaps we could get a sample of his sweat. That might give us some clues as well."

"Yeah, he goes to the gym," Kathrine says, her voice a little stronger. "Monday, Wednesday, and Friday, after he gets done working in the archives."

"Perfect," Irene says, making another note on her clipboard. "Do you know his clothes washing habits? Where he keeps his gym clothes?"

"I mean― I think he usually just throws them in his hamper?" Kathrine says, her voice uncertain. "I'm not sure where he keeps them, though."

"That's alright," Irene says, her voice reassuring. "We can work with that. I'll join you for lunch tomorrow, to observe your brother and see if I can notice anything unusual. In the meantime, try to keep an eye on him, see if you notice anything out of the ordinary."

"Okay," Kathrine says, her voice a little stronger. "I can do that."

"Excellent," Irene says, her voice brisk and businesslike. "I'll see you tomorrow, then. And Kathrine?"

"Yeah?" Kathrine asks, her voice hesitant.

"Try not to worry too much," Irene says, her voice gentler now. "We'll figure this out. Together."

"Thanks, Irene," Kathrine says, her voice grateful. "I appreciate it."

"Of course," Irene says, her voice warm. "That's what friends are for. I'll see you tomorrow."

"See you then," Kathrine says, and hangs up the phone.

As soon as the call with Irene ends, Kathrine finds herself still consumed by the intense arousal that your presence sparked in her. For a moment, she just sits there, cross legged on her bed, feeling a **** need for release. Then, slowly but surely, she acts. Slowly but surely, she kicks off her jeans and slightly sodden panties to fall into a pile on her floor.

Laying face down on her dorm bed, she pulls the blanket over herself, feeling shy and awkward about what she was about to do next even in the privacy of her own dorm room. But the need to relieve the pressure building up inside her is overwhelming, and she can't resist any longer.

She begins to rub herself, tentatively at first, then with increasing confidence as pleasure builds within her. She bites and humps her pillow, imagining you there with her, taking her from behind and pinning her down on the bed. In her mind, your big hands roam her lithe frame, pushing and holding her down to the bed with your weight, the imaginary sex rough but loving.

As she touches herself, she starts to vocalize her desires, imagining the dirty talk that might accompany such an encounter. It's dorky and awkward, lacking any of the swearing and gritty realism of true passion, but it's the best her mind can conjure in the moment.

"Y-you're all mine," she whimpers, her voice muffled by the pillow.

She pictures you responding, your deep voice growling filthy nothings into her ear as you claim her body.

“Oh!” She moans, her hips pumping up and down faster, muscles flexing as she rides her increasingly damp pillow, biting into it to stifle her voice as best she can. “I'm the youngest ~ahh~, so you have to ~gah~ pay attention to me! I deserve you! All of you! ~unf~ You're my big brother―!"

The thought sends her hurtling towards the edge, and she vocalizes her responses to your imaginary words, her voice rising in pitch and volume as her climax approaches.

With a final, sharp cry, she tumbles over the edge into a crushing orgasm, her body shuddering with the **** of her release. The pleasure is intense, all-consuming, leaving her gasping and dazed in its aftermath.

Her post-orgasmic haze is abruptly interrupted by the sound of the door opening. Her roommate stands in the doorway, taking in the sight of Kathrine laying face down, clearly naked, and legs spread-eagled on her bed under the blanket, sweating and eyes hazy with pleasure. The two lock eyes for a long, charged moment before her roommate quietly backs out of the room, closing the door behind her with a soft click.

Kathrine is left alone once more, her body still humming with the aftershocks of her first self-induced orgasm. She is dimly aware that this might make things a little awkward between her and her roommate after this, but in the moment, she can't bring herself to care.
