"I l-like feeling you squashing me, you big dummy. Why do you still always think I'm too small for something?"
"Hey-y, I don't think you're too small for anything anymore. It's just I like to feel you on top of me-e once in a while, too."
"Oh-h, well in that case." Tannsy grinned, nudging Clark to roll. Almost immediately after her warm legs closed on his long prong she began fidgeting. "It's not the same," she fretted. "When I-I'm on top it has to be in-n."
"The end of it does feel kinda cold out there behind you."
Tannsy hunched her behind high enough to capture Big Pee-pee between their bellies and then inched up Clark's body until the end of his dick just started to edge over her pelvic ridge. She tilted herself back, then, and captured it with the dimple of her cunt, wriggling her hips until the big knob popped in. She sniffed her smug little grin of triumph and wormed backwards until their bellies met hair to hair. She slipped her arms through Clark's armpits and laid her cheek on his chest. And stayed that way for almost ten seconds before she again raised her face to her brother's.
"Hey, were you mad at me cutting Virginia out right in front of everybody like that?" she asked.
"N-no, of course not, honey, but Cissie's whole idea of the topless party was to get you turned on to somebody else in the first place."
"Oh, I knew that, you big dummy."
"Yeah, and I knew you'd know right off. I thought there for a while it had worked, though, you know?"
"With Jerry, you mean?? My God, honey, I figured everybody else would think I was turning on to him but I never thought you-u would believe it."
"Well… I suppose I'm supposed to be sorry it didn't work out but I'm not."
"Aw, honey, you're so goddam sweet sometimes." Tannsy kissed her brother. She giggled suddenly. "Kinda backfired on our super-sexy sister, though, didn't it. You see her cutting out with Pete after he was standing there watching her boobs jiggle all that time?"
"No-o, I wondered where she went. Pete!! Shit, Pete Fleming's never going to be able to satisfy her-r."
"No, but she likes to do it with him once in a while because he always wants her to so bad and never dares to say so. And I saw Virginia and Jerry sneaking upstairs when I was coming through the house, too, so they'll swap around. She'll be okay. -Am I being selfish if I say I'm glad?"
"'Course. So am I."
"I mean like it was nice us three together on her birthday like she wanted, but today I wanted it just you and me alone, you know?"
"For what?" Clark asked superinnocently.
"To f-fuck, you dumb shit. Hey, let's get in TV watching now, okay? All of a sudden it ain't in-n far enough. All that air between us?"
Clark released Tannsy with an indolent chuckle, both their stomachs tightening with the suction of his cock coming out of her cunt. The lazy husband, he lay and watched Tannsy's lithe little wife-body as she bustled around plonking and arranging pillows. Finished with her maneuverings, Superbrain Sister had her brother lying half on one hip with his back and neck twisted to one pillow to see the television screen. She was lying at right angles to him with her back propped against a second pillow and both legs over Clark's raised hip. Her warm behind was snugged firmly into his groin and Clark's super-stiff cock stabbed through the puffy lobes of her cunt as deep as it would go in her hot little body.
They were both half asleep when a super-cultured snicker flitted across the room from the kitchen doorway.
Clark and Tannsy came apart like a fragmentation bomb in a vacuum tank, his stiff cock coming out of her tight cunt with a thowk that resounded like a shotgun blast in the sudden dead silence. "Elaine!" Tannsy gasped. "Miz Compton."
"Yes-s," Mrs. Compton said in perfectly modulated tones, her cool eyes running Clark's cock from the black mat of wet coils in his crotch to the bulging red knob waving high on the end and glistening with his sister's slippery cunt juice. "What a beautiful arrangement for watching television."
Oh man, was Clark's first thought. There wouldn't be any raping of this one to get her involved. She'd love it.
Mrs. Compton's eyes flicked from Clark's suddenly dead cock to Tannsy's compact little body and then she walked-strolled-to the big rocker. Her tall willowy body moved with the same fluid grace Karen Somers' did when her mind was all sexed up and yet there was an odd clumsiness about her, too, as if her knees suddenly wouldn't hold her.
Tannsy scrambled to a sitting position on the edge of the bed beside her brother, together to take on the world.
"I wasn't really spying on you children," Mrs. Compton drawled. "I stopped for a word with my daughter and when I didn't find her at the swimming pool I fully expected to find her in here with you, Clark. You two really should learn to lock doors if you're going to engage in… such close family relationships.
Tannsy shot a look at Clark. "A-gain-n??" she wailed.
"I d-did!" Clark protested. "I stopped on purpose to lock it."
"You must surely have had your mind on something else, Clark. Understandably, of course. I knocked and, assuming you too busy to hear but being in rather a hurry, walked on in. And, goodness, with all those people out there on the lawn and everywhere, some of whom must surely be looking for places to hide by this time."
"The back door," Tannsy groaned. "We forgot the back door."
"I do have to admit you make a beautiful little couple, but I must also say I don't exactly know what to do in these particular circumstances."
Clark shot a startled glance at Mrs. Compton's face. She seemed cool and amused, still, but that cultured speech of hers always got super-cultured when she was beginning to turn on. Just before it always broke down completely to a sexy bawdiness that turned on everybody around her. The thought struck him, suddenly, that while Tannsy knew he was getting it while she was away, she had never actually seen him get it on with anybody. Maybe that's what it would take.
"Why do anything about it?" he said with a calm boldness he himself didn't believe. "Why not join us?" He felt Tannsy give a surprised start beside him and quickly nudged her with his knee to keep quiet.
"Oh, I couldn't, thank you, Clark. I… have tennis."
"Aw, you can play tennis any time. It's too hot to play tennis anyway." Clark tried not to hold his breath too obviously. He had never heard of Mrs. Compton doing it with anybody in front of witnesses. She was an absolute freak on protecting her husband's career. But her eyes did flick involuntarily over his naked body again. And then Tannsy's.
Elaine Compton was exactly the same age as his own beautiful mother, almost to the day, but, like his own beautiful mother, she kept her firm body firm and her gorgeous ass gorgeous by ritualistic exercise, not by rubberized thread.
Also like his own beautiful mother, Mrs. Compton could get away with wearing the abbreviated sports clothes their daughters wore. Even as Clark watched, she nervously uncrossed her beautiful suntanned legs to cross them the other way. Her short short tennis skirt belled up her smoothly muscled thighs, showing a flash of pastel green panties and a super-white sliver of creamy crotch meat he wasn't supposed to see way back there in the dusky shadows between her legs. He felt a stirring in his prick and it hadn't even been her cunt he had seen. Yes-s, this was one sexy sexpot outsider he could surely get it up for, even in front of Tannsy.
"It seems such an imposition. -You really want me to stay? It's no good if we're not all-l willing, you know."
"Of course I want you to stay-we want you to stay."
Mrs. Compton leaped from the chair, suddenly with it all the way. "Okay," she chirped, "but first let me lock that back door. I-I can't take your-r kind of chances."
"What the hell you doing!" Tannsy hissed as Mrs. Compton skipped happily from the room.
"We've got to get her into it just like we did Cissie, dummy. So she can't ever let it slip to Mother."
"She-e would never tell M-Mama!"
