"My nipples, John - you could start rubbing them again." These were the first words that Kelli was able to utter as her head began to clear from the fog of her mind blowing orgasm.
"Just be a little more gentle now. Right - nice and gentle - mmm." Then, recalling her climax, "That was so AMAZING!" Finally, as other senses and faculties started to register, "My god, you're still hard!" With that she began, once more, slowly rocking her hips.
"How could I not be," John whispered, although, in truth, even he was surprised. John's still muddled brain responded reflexively to the word "nipple," and he restarted his massage of those ever so stiff nubbins despite the fact that he could not have told you the time of day, the day of the week, or even in what city he lived.
Two minutes prior, despite all odds, neither John nor Kelli had lost their balance while simultaneously writhing through the most sensual, erotic, and explosive orgasms that either had ever experienced. Kelli, despite her extensive practice at maintaining perfect silence during her private, in-class, nipple orgasms, had not been able to hold back from emitting a long, low guttural moan. John, for his part, simply had held his breath until the urge to breathe became too great. He was still planting ever more of his seed in his sister even at that point.
All he knew was that he was DEFINITELY no longer a virgin, that he had just poured buckets of hot cum deep, deep inside his super-hot sister's sopping pussy, that he was still holding her sensuous, firm, D cup tits, that they were both naked, and that he had just watched his Mom, Marie, experience her own intense nipple orgasm by spying on her through her bedroom window. In fact, through it all (and even now), his eyes were focused firmly on Marie's throbbing nipples as they rocked back and forth on the tips of her upturned boobs as Marie's continued to pant, face up, on her bed. The way her turgid nipples both lined up in profile was a sight contributing to his rigidity - he loved that view!
Marie's intense nipple orgasm had been brought on by nipple play (lots of nipple play), the erotic display of her underboob in the mirror, including portions of her areolas, in the mirco-bikini, and the final tweak that her nipples had experienced when they popped free from the bikini top. That, along with the growing and exciting resolve to wear such a scanty bikini in front of her own son. Add to that the fact that her nipples, previously perched just over the edge of her half cup bra, had kept her sexually charged at work, and that final nipple pop pushed her over the edge - WAY over the edge!
For her part, Marie was also fighting through the fog of her own orgasm. As she did so, her hands rose to the exposed undersides of her breasts, which she gently caressed before her fingers drifted north to find her nipples, which she very gently pulled and twisted as she relived the intensity of her explosion.
Then, reality crept back in. "The kids - they're waiting for me at the pool!" she whispered. "I'm surprised they haven't come to check on me." But first, she realized, she'd need to clean up down below in the bathroom. She rose on unsteady legs, nipples still exposed under the tiny bikini top, and headed out of her bedroom door.
"Um ... Sis, I think we'd better find a way to clean up, don't you?" Nevertheless, he kept slowly pumping his dick into her and playing with her nipples.
"Don't panic - she doesn't have on the bikini bottom yet. Probably cleaning herself up. But you're right. Give one more big thrust and let's get to the pool. Oh, that feels good!"
"You want to just jump in the pool? But what about all of our - uh - fluids?"
"That's what we've got chlorine for, silly. Oops - she's coming back in for her bottom piece. Stay low, grab your suit and hurry!"
John took one more glance through his Mom's window. Amazing! Her nipples were still stiff and still poking out from under the bikini patches. But then he turned to follow Kelli's trim ass down the path, marveling at how her swaying boobs bobbed out left and right as she crouched out into the open.
Still naked, they walked into the pool and dunked down to shoulder depth while wiping away the residue of their encounter. "Jeez, John, how much spunk did you plant inside me? I don't think it's ever going to stop oozing out. Here - help me with my top."
John, who had swished his slowly shrinking dick around in the water and had pulled up his trunks, fumbled with the straps, standing behind Kelli. "This is another silly question, Sis, but ... this is our little secret, right?"
"Hey - incest may be legal here, so long as we don't marry, but remember, Mom's a lawyer AND my mother. No telling what she might do to you." With that, John's dick shriveled to the size of a gherkin just as he finished the last tie.
Sensing John's deflation, Kelli swung around, gave him a wink, and flashed him a dazzling smile. "I'm kidding, John! I'll only tell on you if we DON'T do this again. And again. And again! Come on, race you to the end of the pool!"
Poor John was left with an image of Kelli's buoyant boobs, hard nipples clear as day under the transparent bikini, and a head still spinning at Kelli's topsy turvy banter. But in a few quick free style stokes he had caught up with his breasts stroking sister.
Marie, meanwhile, had pulled up the thong bottom of her suit, then glanced in the mirror. "Oh, my, those
are
stiff nipples," she murmured, "but it's time to put you away, at least for now." Reluctantly, she adjusted the triangles of cloth to cover her nips and yes, even her areolas. But the strength of her orgasm had left her more, not less, determined to see whether she could wrest John's attention from his sexy sister. She wasn't sure where things were going, but she knew that she'd denied herself for far too long.
In fact, as she walked through the house, boobs wobbling softly, the powerful nipple orgasm took her back 24 years to her old lover Rod. She had soon learned he was a jerk, but he certainly did know how to work both her boobs AND her pussy. The more that memory played out, the more Marie realized that playing with her nipples was not enough - she needed a man to fill her up the way her fingers never could.
