The Big Swap

“Could you do me a favor, Kory?” Peter asked.

Kory’s head was down on his six-pack abs, facedown, her hair rolling over both her and him like a blanket the two were snuggled under as they lay, naked, on the carpeted floor.

Kory laughed gently. “It would be my pleasure,” she said, and started down his flat stomach, with its intriguing ridges of delineated muscle, which became the rigid flatness of his loins, scratched over with rugged pubic hair, and then his masculinity. Semi-hard, rising up from his groin in a soft arc, as if even the lust Kory’s heavenly body inspired wasn’t enough to lift the entire heft of Peter’s member.

But Kory knew that, big as it was, that shaft was capable of becoming fully erect—it showed every sign of returning to a state of hardness within moments of her plump lips going to work.

“Not that kind of favor,” Peter said.

Kory’s lips were already puckered for the first few tasting kisses she was going to use to play Peter’s manhood back to its fully stiffened length. She stopped in surprise, in utter shock—her eyes opening as wide as her mouth would have to be to go down on his big staff.

She’d never before been turned down for a blowjob and the thought of what could get a man to put her off fired Kory’s imagination even more than the prospect of having her mouth stuffed with such a sizable prick.

Did he want to fuck her up the ass? He never had before, but even her pussy could only sate a man for so long before he began to consider other avenues of pleasure in Kory’s decadently fleshed body.

Kory didn’t mind the prospect at all. Feeling Peter’s cock inside her was always enjoyable; she was as open to the novelty of experiencing it in other ways as Peter must be to experimenting with her body. Or was it something else?

Faced with Peter’s massive endowment, she quivered with ideas of sexual intrigue. The dirtier the act, the better. To her, it was a sign of a healthy relationship that after the initial bloom of discovery, now their sex life was growing more uninhibited. Just as she’d never stopped finding lascivious ways to explore her bond with Dick, she wanted to try as many thrills with Peter as she could while it was possible.

Did he want to watch her fuck someone else? Would that make Peter more comfortable with the inevitability of him going back to his own universe and her moving on to another relationship? Maybe two or three men, or even more, one right after the other while he watched with scientific curiosity for erogenous zones and sex acts that he could attempt the next time he possessed her.

The thought was perfectly pleasing to Kory, exciting her as though to make up for how she’d lost out on getting to toy with Peter’s erection in her mouth. More ideas came to her, parading through her mind in autoerotic sequence.

It was probably more likely that Peter wanted to watch her with another woman. Many Earth men found it a turn-off to experience the same woman in rapid succession with another man, but the prospect of having a woman who’d been lubricated with the mouth-love of another attractive female? That made erotic sense to them, the same as Kory would enjoy tasting a man’s sperm from the inside of the woman he had pumped it into.

And it was as close as a man could come to knowing the joy of Sapphic lovemaking. Kory would happily display it to him, with Peter staring over the shoulder, watching her nimble tongue pleasure and play with a creamy cunt, before she assuaged his lust by giving herself to him and showing that masculine loving was more than satisfactory to her, much as she enjoyed the feminine as well.

Kory seethed, staring at Peter’s cock, electrified by her fantasies of how he would allow her to titillate it.

Would he like to watch her fuck a Bolovaxian? Oh yes! A lovely, elephantine Bolovaxian with a cock to match! These kinds of interspecies flings caused no anxiety in Kory; humans having been the ones to have long since taught her of the joys of mating outside her star system.

She had, in fact, sucked off a Bolovaxian just before meeting Peter. She’d loved the way the big, bulky thing whined and grunted just before he filled Kory’s mouth with more cum than she knew what to do. She’d swallowed as much as she could, but it was like trying to drink from a gallon jug that’d been turned upside down. Inevitably, much ended up being worn instead of ingested.

It made Kory ponder, once more, how self-explanatory it was to wear so skimpy a costume. Would it not be tremendously more difficult to wash if it had covered more of her, and so ended up soaking in even more semen than it had in its present state?

All Kory’s ideas to lance taboos and indulge in kinks made her so aroused that she just had to stick her tongue out and lick the tip of Peter’s cock. “You mean you don’t want me to do this…?”

Peter’s manhood snapped upright even faster than Kory had anticipated, coming to stiff attention as though it hadn’t just vented a bellyful of lust into her slit.

“I mean, it’s not that I don’t want you to, I’m just saying that’s not the favor I was going to ask…” Peter said hesitantly.

Kory grinned at his stammering reluctance to dissuade her. But, peevishly, she held her tongue between her lips now. She’d gotten too excited, thinking of what debauchery he might have planned, to settle for a blowjob now.

“I suppose it wouldn’t be much of a favor,” she purred. “Not when I’d enjoy it so much.” Then she couldn’t help herself again; she ran her tongue up his shaft and delighted in the flavor all over again. “So what is it you want me to do that’s a favor? Will it hurt? Is that why it’s a favor? Because I don’t mind a little pain… so long as you show me how much you appreciate all I endure for you…”

“It won’t hurt,” Peter assured her. “It’s for later… something I want you to do…”

“Do tell me, my heart of sweetness.”

“You know back home, there’s this girl… Kitty Pryde… I sorta took her under my wing. She’s pretty young… kinda sheltered… I need someone to talk to her about… about girl things.”

Kory’s eyebrows rose with conspiracy. “You mean sex?”

“Yeah, I guess. I mean, I know… I’ve never met someone who enjoys sex the way you do, so I figure you could explain things to her… tell her how to look out for herself, sort of? Enjoy it all without getting in over her head.”

Kory sat up, straddling Peter’s legs, to look him in the eye. He looked concerned.

“Why did you pick now to ask me?” she questioned him. “I’d be happy to assist you in bringing a young woman to sexual fulfillment, but from all I know of humans, they prefer to separate subjects of this nature from what we’ve been doing. There were many people in Dick’s life that he greatly disliked discussing when his cock was hard and I was hungry for it…”

Peter now looked more sheepish than serious. “I suppose I feel a little guilty. Kitty, she’s the reason I got so worked up. And now that that’s dealt with… or at least on hold,” he said to the crestfallen look on Kory’s face. “I thought I should get the matter settled.”

“How did she work you up?” Kory asked, intrigued. “She’s in another universe.”

“Yeah, I know. I looked in on the old homestead this morning. That… vibrational viewer in the Flash Museum—I still have no idea how that works.”

“Yes,” Kory asked, still more interested.

Peter had told her about Kitty before, and she’d seen her in a much earlier collision of their universes. Kitty had been too young for anything of that nature then, as girlishly immature as Gar was boyishly immature. But even then, Kory could tell that Kitty would grow up into a stunning young woman, with a charisma that would make her truly irresistible.

It would be sort of exciting to share the facts of life with her; if she needed any explanation. Kory doubted that Kitty was as innocent as Peter might assume. Peter’d shown her pictures of his old life on his phone while feeling homesick. Kitty dressed to excite those who saw her, and such a brash, self-assured woman wouldn’t do nothing with that excitement.

But what excited Kory was the idea that Peter had gotten worked up because of something he’d spied Kitty doing. The implication was thrilling. On Earth, there were many who were interested in domination—tops and bottoms—but on Tamaran, that desire was expressed in the form of teaching, guidance. Expert and student.

Kory had always wanted to learn her sexuality at the foot of an older man, once she was mature enough herself of course, but she’d been robbed of that chance by her sister’s machinations. Now, at least she could experience that intoxicating dynamic from the other end. Showing this Kitty how to please and helping her find what pleased her.

“Tell me more,” she urged Peter.

He paused, maybe a little ashamed of the reaction he was now telling Kory of, or maybe reluctant to turn Kory loose on the girl he was used to thinking of so innocently.

“Tell me,” Kory pressed, her eyes glowing bright. “And while you do, let me get my reward for doing you a favor…”

She curled onto her flank and began gently mouthing the end of his erection, watching his face as it vacillated between the sensations she was causing and the memory he was sharing. Her clever tongue glided around his cockhead, animated by the flickers of lust Kory felt between her legs and in her seething mind.

Peter’s eyes closed: “I just wanted to look in on her, make sure she was doing okay, but the moment I got there, the doorbell rang. Kitty was in bed. She threw off the covers and went to the door, still wearing next to nothing—just these really short boxers and a T-shirt. Tight T-shirt.”
