She whimpered before the unnatural intrusion. He'd never done this before. Yet, persistently he sunk his thick invading finger into the soft rubbery depths, never stopping, until the palm of his hand lay flat against the moist intoxicating crevice of her beautiful ass.
"OOOooohh! Darling! Darling! Where've you been all these years?" Jan moaned passionately. "Dear God… yes… yesssss! Love me! Use me! All the way, my Darling! I'm yours… yours!"
If he hadn't been so filled with lust, Gil realized he probably would have cried. Not lust in itself alone, but accepted, marital passion aroused by the words he'd never before heard from the lips of this girl he loved so much, and instead, his inner joy was nearly overwhelming him, until he was practically grinning stupidly down into her glazed eyes.
At first, she'd lurched understandably in her effort to accept his rectal impalement, but he'd waited and with passing seconds she began screwing her magnificent, rounded buttocks down onto it. He worked his finger around and around inside her, feeling through the velvety partition of thin tissue the ridges of his own heavy sliding cock fucking in and out of her, until he'd begun a dual rhythm of finger and prick as she moaned wildly beneath him.
His loins were a raging inferno now, his rod growing and expanding inside her as he grunted and quivered, reveling in her hot flesh, increasing the speed and measure of his stroke, tunneling into her savagely while his merciless finger drubbed the depths of her delightful, clenching asshole.
She held him tightly with her strong white thighs, clamping them high around his waist, slackening them and clamping them again. Her soft body was deliciously hot and her head moved in wild, feverish, side-to-side motions as she chewed at her full lips passionately. He saw her dark eyes rolling crazily in their sockets as she tightened and loosened her scissors-grip, winding her lovely legs completely around him while she waved her buttocks lasciviously, then screwed her cunt furiously up his raging prick and her asshole onto his buried finger.
***Lee gaped through the tiny peek-hole, his vision half-blurred by his own thrusting stabs into the voraciously grasping cunt of his obscenely bent-over twin, but he saw enough of his parents' wild salacious coupling to increase the churning in his tingling balls by ten-fold.
"What're they doing, Honey?" Katie hissed up and back at him. "Tell me!"
"Oh Christ!" Lee gasped. "They're going out of their gourds! Dad's ramming it to her like a pile driver… and… and now he's finger-fucking her asshole at the same time!"
"Oh God!" Katie moaned, the mere thought multiplying her own galvanic fermentations maddeningly. "Do… do it to me, Honey! Now! Please… do it to me!"
In, out, in, Lee thrust, his brain reeling with the carnal lust of her plea. His prick bursting into her as if she were some ripe fruit, and her tender young cunt wildly relaxing before his plunge, then swallowing his shaft and holding it fast in a hot, hungry clutch of excited muscles. He saw her slender arms tense as she supported her weight on her hands still clutching at her ankles. She'd begun to groan incessantly and he was gritting his own teeth. His cock seemed swollen and white and he could feel the soft fleshy ridges inside her giving way before his pistoning onslaught.
In near-overwhelming lust, he stretched the trembling orbs of her enchanting ass wider apart with his fingers, watching the pink folds of her moist, glistening raw flesh clinging tightly around his now thundering prick racing into her; then he slid one finger down to dampen it there before easing it up to probe gently at the stretched raised circle of her pink asshole. He felt it automatically resist the invasion, then watched it lewdly pop open as he pressed persistently, his finger slipping slowly into the cringing rubbery depths while she gasped beneath him in a wanton stream of agonized delight. Christ, he thought, one of these days or nights he'd fuck her there with his prick!
"Oooohhhh! Lee, Honey, Honey! Agghhhh! Yes! Yes! Do it! Don't stop! Finger-fuck my ass!" Katie gurgled licentiously.
She could feel electric-like sensations rippling through her voluptuous body at the slow and unnatural penetration into her little nether-hole. Dear God, it felt like a small, second prick sliding into her… and then he was moving it around, routing the gripping, rubbery flesh of her passage, causing wilder fermentations to charge over her quivering hot flesh!
Lee was beside himself in his ruttish excitement. He watched his middle finger in lewd fascination as it disappeared into the depths of his sister's obscenely presented asshole, the snug sphincter clinging tightly to it, and as he began to move it around inside the hot, spongy channel, he could feel his own thick cock through the thin separating partition of flesh… feel it ramming into her vagina… and she had begun to move her buttocks back rhythmically toward the impaling shafts, undulating her hips in lurid, voluntary circles, abandoning herself completely to the insane fucking he was giving her.
Katie had fallen into a spell of sheer carnal entrancement. The delicious pressure building rapidly now inside her loins and belly was erotic bliss! She was going to cum! Her beautiful Lee's long thick cock and plunging finger were going to cause her to explode within at any second!
"Oh! Ooohhh! Harder, Honey! Harder! Please… fuck hard!" she pleaded. "I… I'm going to cum, Darling! Yes! Yessss! I'm going to cuummmm!"
Katie's words alone were enough to trip his own climax. He pulled his probing finger from her asshole, the abrupt extraction causing a lewd hissing sound, and clutching at her taught, smooth hips he jerked her back onto his now smashing rod, feeling her thighs and buttocks sweeping wider apart before his wild, ass-flattening attack as he felt his own seething sperm pumping up from his balls and raging along the tiny channel toward the knob of his prick in brain-shattering ecstasy!
For Katie, it had already begun, the great bursting bubble inside her, just as her brother's magnificent cock fucking into her from behind began shooting its white, hot load deep into her clasping cunt. It splashed maddeningly around inside her and she could feel it foaming back out her cuntal lips to drench the pubic hair of his pelvis and dribble down to cover his balls.
She heard him groan and whimper as she screwed her buttocks back onto his still-spewing shaft, biting at her own lips to contain the cry of utter enchantment rising in her throat. Again, she felt her body explode into what seemed to be an inexhaustible array of colorful, bursting stars and she couldn't hold back the whimper as the very life seemed to drain from her… until she thought she was going to tumble forward onto her face!
***Gil realized proudly that his beautiful wife beneath him was moving rapidly toward orgasm; then, for one brief, unsure moment, he thought he heard a groaning sigh from somewhere behind him, but as Jan began to whimper and strain, he quickly forgot all else to listen to the ecstatic music of the erotic sounds coming from deep in her chest… incessant gurglings that drove him to even more violent, vicious strokes.
"Oooohhhh… Gil, my Darling… fuck me to death! Hard! Hard! Screw me hard, my lover… harddd!" she cried up at him, foul obscenities beginning to gush from her lips in her desire to reach the pinnacle and take him with her, her moist, writhing crotch bucking furiously up against his loins and buried finger, her legs suddenly drawn back until her knees crushed her heaving breasts, then she locked her ankles over his shoulders and rode her cunt wantonly up his cock to cling there for a moment in completely enslaved rapture.
"Now, Darling! Now! God… oh God, yes!" Jan began to wail. "I-I am Darling! I'm cumminggg… cuuummmmmiiinnnngggg… aaahhhhhhhhghhh!"
