Half an hour later, they had met Melissa in front of the airport. She was as good-looking as he remembered, her long blonde hair picking up the stiff breeze nicely. She was clutching a little golfer's cap to her head, one of her weird styles, and had on a thin fall jacket with a long black skirt. Her round button-nosed face wasn't on its happiest day, he could tell, but he knew Nall would be at work soon. Isaac's penis was already most of the way toward recovery from coming inside Nall's ass, and he tried to hold back his massive arousal at the sight of his sister -- knowing he'd almost certainly have her naked soon, and making her grow big with eggs.
Isaac introduced Nall as his new girlfriend; they'd been dating for only two weeks now, but they'd really hit it off, he said. Melissa was stunned at what had happened to Isaac in the four months they hadn't seen one another -- she would have sworn he had gotten taller, but he told her he'd had back surgery to fix a bad disc he hadn't even known he was suffering for years, and it got rid of a slouch he'd had for a long time without realizing. Nall fogged up her mind a little to make her buy it. His new beefy physique was the product of a good diet and exercise, of course. The last physical change they figured they could just tell her the truth about, once they got to that point.
Isaac hefted her luggage, walking the two girls back to his car. Nall tried to keep up the appearance of small talk, but her inexperience with acting like a local human was becoming increasingly obvious. He quickly interrupted when Nall replied to Melissa's comment that she lived in "the capital; oh, I mean DC..." by asking which state Washington DC was the capital of.
"Don't mind Nall, M, her English is good but she learned most of it from American teachers overseas, so she's a bit clueless about the US itself."
"Oh... I was going to say!" Even Nall's mind control couldn't have kept her ignorance hidden forever. "Where did you learn all that?"
Isaac knew their original plan was shot, and before Nall could say anything he jumped in. "Her parents escaped with her from North Korea when she was nineteen, actually. Really wild story. She's the one who seduced me, really." They had a laugh, and Isaac spun a wild tale off the top of his head, impressing himself with his own ingenuity. Nall seemed to be the most interested in the story, a detail he hoped Melissa wouldn't notice.
By the time they'd pulled up to his spot on the parking deck to his condo, Nall was an orphan and engineering PhD raised in Switzerland and Dubai, and had no memories from before she was nineteen. Her parents had been CIA assets who risked their lives to warn the US about an impending nuclear missile test, but the thing had exploded on the pad anyway. Her parents were found out, and they escaped on a Zodiac boat with a SEAL team and boarded a US submarine, Nall suffering a head injury in the escape. He intentionally made it sound absurd, knowing Melissa would focus more on figuring out what was wrong with the story rather than what was wrong with Nall.
"We're here." Isaac opened the door to his flat, lugging her bag inside. He set it by the door to his bedroom, quickly closing it when he saw the nude Clara resting on the bed. He'd forgotten to share the details of he and Nall's plan with them. Fortunately, Melissa never saw within. He wondered idly where Jessica had gotten off to. Nall sat next to Melissa, probably closer than the other woman would be comfortable with normally, but Melissa seemed okay with it. He fixed them all something to drink while he heard them talking quietly on the couch, unable to make out individual words. The two suddenly laughed, then returned to talking.
He brought three glasses of iced tea over, setting them on the coffee table, and sat down in the love seat. He rested squarely on the spot where he knew he'd fucked Nall's ass not too long ago. Isaac checked the clock. They had less than five minutes until Nall changed back. Nall seemed to notice too, and went back to talking to Melissa.
Isaac leapt in with a basic question. "M, how have you been doing?"
"Oh, um, so-so I guess."
"I meant... you know. Nall actually has some experience with something like what you do," he lied, getting an instantaneous glare from Nall, "and I occasionally sound off on her for advice on what to say to you."
"Um -- wow. I mean, okay. I don't really try to hide it, but I don't go around announcing it either. You two must get along so well, you've only been together two weeks!" She smiled. "But -- uh, well, you talked to me the other day. I'm getting worse. I hate it. I know it's happening and I can't do anything about it. On my days off work I just lie in bed sometimes, all day."
"What about that last medication you were talking about in Seattle?" They'd seen each other there last for a cousin's wedding.
"No good. It reacted badly with one of the others that does work. One in twelve with that combination, they say." Melissa seemed glow for a moment, looking at Nall. "But I've been feeling pretty good since I met up with you. You two have so much energy, it's kind of infectious."
"Daaahhhh...." Nall let out some air, falling back into the couch. "Done." She looked at Isaac, who stared back, and Nall mouthed silently to him. *She's bi now.* He became a little more aware of the half-erect state of his pole, limp in his pants -- for the time being. He knew the thought of his sister now being permanently altered to be attracted to girls as much as guys would have it pretty hard soon.
"Done what?" Melissa seemed suddenly uncomfortable.
"M, there's no real easy way to segue into this, so Nall and I just figured we'd come out with it."
She looked puzzled for a moment, then brightened. "You're getting married!"
Isaac paused. It wasn't an unreasonable conclusion, though it was completely wrong. "Ah -- no, uhh... it's actually-"
Isaac was interrupted when Nall suddenly turned bright red, from head to toe, within the span of roughly five seconds, and her imnir coloration returned -- her fingers, cheeks, parts of her face and breasts, and other extremities were shaded slightly orange, and there were small yellow and teal spots arranged tastefully -- or so Isaac though -- all over her. Melissa stared at her blankly for a few moments, then suddenly yelped and backed off, hand over her mouth. Melissa seemed to contain herself suddenly, then reached out a hand and touched Nall's cheek, which was about as warm as a person would normally be -- no fever or unusual heat. "Um -- are you okay?"
"I'm perfectly fine." Nall nodded, taking her own hand and putting it on Melissa's cheek. "Sorry, I think Isaac was hoping for a better way to drop this on you. I'm an imnir. Greetings, Earthling." Nall looked away, saying it in a monotone. Isaac grumbled to himself; *does she have to do the take-me-to-your-leader thing with Melissa, of all people?*
"What's an imnir?" Melissa seemed lost in the finer features of Nall's body, her yellow patternings and small turquoise spots.
"Oh. I'm an alien. Alien to Earth, anyway." Melissa's eyes widened.
"Um -- oh my god -- no way-" Melissa sounded alarmed, but she never backed away, continuing to study Nall in detail. "It's not make-up?"
In response, Nall unbuttoned the top of her shirt, showing more and more of her chest to Melissa. His sister watched in fascination as Nall stripped off her top, revealing her whole red torso, covered only by a black bra. "I did a couple things to your brother. You didn't really think he got that big from dieting and working out in four months, did you? Or that he got six inches taller?" He guessed that Nall released Melissa from whatever effect was clouding her judgment in that moment, because his sister suddenly blinked in realization.
"Why?"
"Why are we telling you this or why are we doing it?" Isaac rolled his eyes. Nall asked some weird questions sometimes.
