She started to say something, then had a better thought. Just leave her alone and attend to herself like she'd been wanting to do. Her little sister obviously wouldn't raise a stink and tell their mother on her for doing the same thing she was doing. Karen let her sister be and turned her attention back to Rodney and Jerri, who were both now groaning together like a duet, Not, perhaps, the kind of duet you'd hear in a Sunday school choir. But a duet nonetheless.
Jerri still had one of Rodney's legs trapped between the damp surfaces of her thighs and was rising off the bed to meet his every thrust. But his motions, which had been slow and purposeful for so long, were rapidly increasing the pace. He was saying something along with all his moaning but Karen couldn't, make out what it was and she didn't think Jerri could either. Jerri's long black hair was all messed up. The ribbon had long since fallen onto the bedspread and she appeared so excited to Karen that she didn't believe her sister would've cared what Rodney was saying even if she could hear him.
Her own panties were thoroughly wet by now and Kathie's surprising and blatant masturbation removed the last barrier against her getting in on a little of the action too.
Her lips felt dry as paper. Watching the pair for so long on the bed had made her pubescent genitals crave attention for ever so long. Now she was finally going to be able to do something about it. She glanced aside at Kathie to make sure she was still occupied with herself, and saw that she certainly was. She seemed totally oblivious to everything except the couple on the bed and the touch of her fingers against the soft, damp vulva. Karen at last hoisted the hem of her shift to a point just below her bra and eagerly stuffed her hand into the damp front of her panties.
With the moans of Rodney and her older sister filling her ears, she delicately felt her way through the sparse, moist ringlets of her blondish pubic hair and felt the slick surface of her outer lips at her fingertip. She rocked forward and moved her finger and thumb across the sensitive wet flesh while her glazed eyes locked on the scene in the other room. She felt her breath catch at the thrill of the touch and sensed a mellow warmth filling up her entire pubic region. She knew then that she had to keep doing it no matter what Kathie was or was not doing, or anyone else.
Rodney still had his mouth plastered on the tip of Jerri's moisture-beaded breast, but their movements had become so vigorous that he was losing it every second or third time he stroked her clamoring vagina. She strained hard against him and the move took her breast entirely out of his mouth. She was rising nearer and nearer toward her release and the only thing that mattered to her was keeping the stiff, wet shaft of his organ going in and out her soft front.
She stretched her arms as far down his back as possible in a desperate attempt to get more leverage. She felt the hard muscles of his thighs grinding against the smooth tops of her legs and heard his breath growing more and more jagged. Her heels were all the way down against the bedstead now and she was pushing against it with the soles of her feet. The hot well of her desire was filling fast and she needed all the help she could get to absorb the ecstatic frenzy of Rodney's powerful thrusts.
They were no longer groaning; they were grunting now, grunting with irregular noises as though speech were beyond them. She heard Rodney begin rasping like a coal burner and then felt her vaginal heat surge toward the flash point. A rapid quivering shook her loins to the core. Suddenly she heard a deep, muffled sob and felt a stream of hot liquid erupt against her ravenous vaginal walls. Even her grunting stopped. She sank her teeth into Rodney's shoulder and with a stab of ecstasy that seemed all the more intense for her complete silence, she was impaled on the quick, bright point of a screeching climax.
For a few seconds she pushed hard against the bedstead and treated herself to the sensual, quivering little orgasms that followed the first one. Then a wave of heavy torpor enveloped her body and she sank with pleasant fatigue into the damp bedspread.
Rodney was still breathing hard and lying with his spent organ against the drenched, springy coils of her muff. It was too much, she needed more room now. She rolled sideways and he fell like a rock, burying his shoulder in the mattress and then sprawling on his back beside her. She wiped her brow with her forearm and lay luxuriating in the mellow afterglow of their heated lovematch.
The girls still stared through the air-conditioning duct. They hadn't missed one second of the performance and their activity well demonstrated it. Both youngsters still applied their industrious fingers to their exposed organs-maybe Jerri and Rodney were finished, but they were not through by a long shot.
The neophyte masturbators had reached a point of diminishing returns with themselves and were succeeding only in prolonging the pleasurable sensations without any real chance of enjoying the kind of release that had apparently been shared by both persons they'd been watching.
The fact was that although both girls had indulged a few times in self-stimulation neither of them had ever experienced an orgasm. Karen had been amazed when she discovered Kathie playing with herself because she remembered that she'd never started doing any herself until she was eleven or twelve. She thought back and remembered several times when her genitals had felt awfully good while in a hot tub of water or maybe after one of those dreams she could never quite remember, but she was certain she'd never consciously touched herself there with her fingers as Kathie was doing.
At first it had been merely pleasant to touch herself in the forbidden place between her legs but during the past several months it had become deeply pleasurable to her even though she didn't do it all that often. She'd heard from a few older girl friends at school enough to make her aware of what might generally be expected. It seemed to her that sometime the groovy thing her friends called "coming" would happen to her.
Even though the ultimate thrill had thus far been denied her the torrid sex session she had just witnessed drove her closer to it than she had ever been, she believed. She slowed her manipulations of herself to a gentle, irregular touch and felt the excitement ebb away as gradually as it had come. When she looked at Kathie she saw that she, as well, had slowed the movements of her fingers inside the tender swelling of her tiny orifice. She was mystified by the way Kathie was bent over with her face as close as she could get it to the smooth, hairless little lips. She seemed to be examining her genitals more than playing with them.
"Does yours do like this?" she said abruptly, looking up suddenly and catching her sister's eye. Her guileless attitude made Karen feel guilty and embarrassed by comparison.
"Uh… what do you mean, does mine do like what?" asked Karen with only a trace of impatience.
"Well, it feels real good to rub it but after a while it gets real dry, you know, till it kind of hurts unless I stop," Kathie replied matter of factly.
"Oh, well, that's just because-”
"You mean yours does the same thing?" Kathie broke in.
"No, but it did when I was your age." Karen's continual preoccupation with her developing body was once more exhibiting itself. It occurred to her that this was yet another way in which she was more, "grown-up" than Kathie, so she was delighted to explain.
"No, silly, mine's different. Yours will be too when you get as old as I am. See, what's wrong is that it's too dry. When you frig it, it feels good but it needs to be real wet to make it keep feeling good for a long time without hurting.”
Although Karen's sexual excitement was gone, the dampness was still quite present on her genitals as well as on the fabric of the panties that covered them. Because she was still wet there it was very easy to answer Kathie's question. But she was naturally curious about Kathie's practice of the secret act. "How long have you been doing that, anyway? I didn't know you ever did things like that. You better not ever let Mom catch you at it”
