"What now?" she whispered.
"Whatever. Start something and I'll go with you on it."
Tannsy grinned, pecking him another kiss. "If it was all that good for you we've got to remember to try it when we have more time, hey? You ready?"
Pulling the Jolly Clean Giant up between their tight bellies with both superwarm hands as she sank down Clark's body, Tannsy groveled it sensuously along the moistness of her velvet skin, then between her firm, riot-tipped mounds of special girl excitements and then through the soft red lips of her special little vacuum tank. She sucked his cock head deep and began settling backwards, pulling Clark with her, never letting his mastiff escape her hungry mouth.
Clark followed along with her, gritting his teeth against Tannsy's tiny warm hands trailing feather-like up the backs of his legs as he straddled her graceful body with gradually bending legs and then with his knees. His cock gradually sank deeper and deeper into the moist superheat of her tight lips, her hot mouth, and her rollicking throat until, when Tannsy was lying flat on the floor on double-under legs, the hair at the base of the mammoth shaft was again tickling over her nose and chin.
His mind breaking loose at last, Clark looked down his body and grinned. He sat back on his sister's soft shoulders, feeling the upper slopes of her hard young breasts warm against the cheeks of his ass. He began a gentle rocking of his hips, fucking the big cock in and out of her pouting mouth. The corners of Tannsy's lips quirked in an answering grin and her laughing green eyes took on the sparkle of half-excitement, half-amusement Clark loved. For a moment they were alone together trying some kinky new trick. A just audible moaning groan as if a climax had been reached sounded somewhere in the room, reminding them both they had an audience.
Clark fell forward over Tannsy's head and began to turn his body, twisting his log in Tannsy's mouth in slow, careful moves. Though it was awkward to move in that fashion, he deliberately spread his thighs to show his taut-stretched bag of balls teasing across Tannsy's chin, her flushed cheek, resting finally on the bridge of her nose. He stretched out, kissing, along Tannsy's soft upper legs, thinking even now how good she smelled all over her fragrant body. Resting his weight on his elbows with his hands cupping the cheeks of her bottom, he nuzzled his mouth into Tannsy's gaping snatch to do a mutual pump job as only he and his special sister could do one.
Patting Tannsy gently on the fanny before either of them came too close, Clark began slowly and teasingly to raise his hips, spreading his legs wide to show the girl guests a rearward view of his long wetted staff coming hair by hair out of Tannsy's mouth. Slowly and teasingly, his mouth never leaving his woman's cunt, he hunched his body around until he was lying between her legs. He reached from her sides to caress her super-protruding breasts, facing the crowd so they could damn well see what his lips, his gleaming white teeth and his darting tongue were doing in his sister's wide open cunt which was still thrust high from her doubled-under legs.
Tannsy tipped her head back to throw a cocky upside down grin to their enraptured audience.
Clark wanted nothing more than to raise his own hips and ram his raging Goliath into the broiling slash and clear through the top of Tannsy's goldenauburn head but that was what everybody would expect any ordinary guy to do with any ordinary girl. He put one hand under each cheek of Tannsy's soft bottom and lifted instead, bringing her up with himself as he rose from the floor, still wallowing deep in her cunt when Tannsy was braced on the top of her head.
In absolute luxurious groveling that was no way toying any longer, Clark tongued the hair on Tannsy's cunt, adding lots of spit to her own richly flowing juices and parting the golden fluff as neatly as he would part the hair on his head. He ran his hands up the tanned perfection of Tannsy's voluptuous legs, sucking loudly smacking kisses up the insides of each, and stood fully erect. One hand firmly gripping each of her ankles, he stood against Tannsy's soft ass, closing her legs on the length of his throbbing behemoth and letting the bald shiny red dome poke through between her golden satin thighs like it was her prick instead of his.
Clark tilted Tannsy's body forward then, spreading her legs wide so every son-of-a-bitch there-and every bitch, too-could see and drool over the juicy swollen lobes pulsing gently along each side of the silk-framed shining slit. With a flourish equal in grandeur to his sister's, he exchanged hands on her ankles and spun her to face himself.
Very carefully now because he didn't know whether or not the reverse curve of his unyielding stiff cock would hurt her, Clark put the blunt end to the sweltering lips of Tannsy's tiny cunt and nudged. The head slipped in with an audible squish that made everybody in the place jerk his or her breath as in one great pair of lungs. Clark let them see Tannsy's red-glowing cunt swallowing his big cock inch by slow sliding inch, slanting her body slightly to his own as he slid it in and leaning into hers by about the same amount.
Finally mashed black hair to shiny golden-auburn spun silk, Clark put his hands under the front of Tannsy's slim waist and lifted, holding her solidly on his axle, arching his back to maintain their balance. Tannsy's supple body rose into the most beautiful of arches in a perfect, stationary swan dive, her arms again spreading into the gesture of successful accomplishment.
"Taht-t ta tah-h!" she sang.
Tannsy's body jerked and she began coming in that instant. Clark could feel the deluge from her super-tight cunt squishing out from the stretched lips in steady percolating surges. Her whole body came on quivering even as she stretched out in front of him.
The tickly warm streams creeping down over his balls and down the hair on the insides of his legs drove Clark absolutely mad and he wished to hell they were alone so his baby could let loose that tremendous wonderful ocean of feeling that must be boiling within her tiny body. With an audience, there was that incredible self-control of hers. Tannsy would never allow herself to share with any outsider those special feelings that were exclusively hers and her special brother's. Except for the violent involuntary spasms of her thigh and stomach muscles which none of their guests could see, and her inside cunt muscles which Clark could damn well feel, nobody would know right now that Tannsy was feeling anything other than the thrill of putting on a good show.
Of course Clark couldn't see from this position, but he could plainly visualize Tannsy's fluorescent-like breasts, rounded, pointed, pride-filled, thrusting downward and outward from the arch of her chest. The nipples would be extended beyond belief from the extreme violence of this secret orgasm she would share with no one but him. The very sight, mental though it was, banished the spectators from his mind and pulled the trigger on the most violent orgasm Clark himself had ever experienced.
Gasping in his restricted throat as his burgeoning rod so suddenly began spurting the hot straining tons of semen into his sister's internally writhing body, Clark's legs weakened and he staggered. He went to his knees, falling forward, sobbing aloud and unable to control the sobbing, pistoning wildly into the tight back-spurting of Tannsy's slurching cunt. The upsidedown cunt lobes, squeezed ever tighter by the firm cheeks of Tannsy's strong young ass humping up backwards with every deep thrust to make it better for him, gripped and released in a wild rhythm that matched the pulsing beat of his cock, the firm gripping cheeks of that strong young ass giving way to nothing but that relentless cock driving between them.
Clark lay covering Tannsy then, crying inside that he hadn't been able to keep their special pleasure as private as she had. The mechanics of the show to prove he was her man were one thing but that beautiful perfection between them was theirs, not to be shared with ordinary people.
