Chapter 10

When he saw his son start to spurt off in Nancy's avid mouth, her daddy had begun to shovel his fat prick in and out of Lorraine's cunt-hole in a slowly churning back-skuddle—fucking her from behind, as if they were trained circus dogs standing on their hind legs.

Her hips rolled and his flat belly hit the firm curve of her ass as he buried his prick. Her cunt-sleeve was sucking and clutching his cock.

But before they got into the cum stroke pattern of this coupling, Ricky had finished shooting off in Nancy's mouth and she was lapping up the residue, and Jack and Lorraine, seeing that the boy's cock was still fat and firm, slowed down, saving their own cumming until they had watched some more action starring the sexy siblings.

Nancy drew her mouth up his prick and popped his cock-knob in, polishing it until it glistened a flushed purple hue and began to flare and throb again.

Then she dropped back along the couch and gazed up at her brother, wide-eyed and smiling. She wriggled under him enticingly and sensuously. He was hunkered back on her stomach, his balls lying heavy on her tits and his cock angled up like a howitzer.

"Wanna fuck, Ricky?" she whispered.

His eyes glowed with smoldering enthusiasm. The youth wasn't sure if fucking his sister up the cunt would be more sinful than fucking her in the face—but if it was, so much the better!

"Oh, yeah, Sis!" he croaked.

Lorraine glanced at Jack as he stood jammed to her ass and shoved up her pussy.

"It's all right, isn't it, darling?" she asked. "You don't think we should stop them?"

It was evident from her facial expression and tone of voice that she didn't want to interfere.

"Naw, let the little fuckers go!" Jack rasped.

Which the little fuckers did.

Ricky slid back along his sister's slim belly, dragging his cock and balls behind him. His prick, as if it were a single-minded creature of habit was still aimed at Nancy's mouth—unaware that there was another hot, wet, sucking slot available below.

She spread her legs and he knelt between them.

Her slender body tilted up, belly flat as a board, pelvis cupped in between her hipbone ridges, tits rising like twin hillocks capped by pink pillars.

Grasping his cock by the hilt, Ricky levered it down, his ass jerking up on the back end of his iron hard-on. His cock-knob brushed in her plump, curly blonde vee, then dipped down into her swampy cunt.

His prick stirred in her slot like some sluggish creature emerging from a pool of quicksand.

Nancy rippled and shuddered all through her nubile body at the first contact. Her cuntlips pulled on his crown, sucking the tip in.

Ricky stared at her in awe. Her cunt seemed to be swallowing his prick just like her mouth had. He had fucked her mouth like a cunt and now her cunt was sucking like a mouth, her sexual appetites more than, impressive.

Wriggling and squirming, ass undulating, belly cupped and thighs hooked, Nancy was slowly pulling her brother's cock up into her fuckhole.

He didn't have to hump or thrust, he just hunkered between her thighs as her pussy ingested his cock. He stared down, watching the long prick vanish bit by bit.

One-third of it was buried.

Her cuntlips distended down his prick, gripped tightly, then snatched another inch in. She was soaking wet, yet the fit was trim and tight, her cunt chute massaging his cock, molding to the fat contours.

Now half of his prick was up her.

She stopped sucking it deeper and began to use her inner muscles, clamping the rings around him, running up and down his cockshaft as if frigging him off.

"Shove it up me, Ricky!" she moaned. "Stuff all of that big fucker in me!"

He braced his thighs and tightened his ass, then lunged out. The rest of his pounding prick disappeared up her cunt with a sudden jolt.

"Ahhhhh!" she murmured as her brother held the full penetration.

Her cunt-slot was glued to his cock hilt, his balls jammed to her upthrust ass.

He shuddered as her cunt pulled and sucked on the buried prick, thrilled by having every inch of his cock enveloped in hot, sucking, sibling pussy, and she whimpered with the thrill of having her cunt filled to the very brim with that massive hunk of brotherly prick.

She began to fuck first.

The supple girl pulled her pussy up and down on a few inches of his prick rhythmically.

Then Ricky joined in the action, matching the pace that she was setting.

He pumped it to her as she jerked her groin down, and she rolled her hips as he withdrew, so that he cunt-sleeve was twisting on his stalk.

Cunt-juice was gushing from her pussy each time his fat plunger stuffed her full, turning her crotch to a hairy cream bowl, seeping down into the crack of her upthrust ass, soaking his belly and balls and streaming down her thighs. But as her fuckhole got wetter, the inner rings gripped more tightly to compensate for the slippery lubrication, keeping the sliding friction hot.

She fucked faster.

Ricky stepped up the pace to match hers, throwing his cock into her in counterpoint.

And, in the kitchen doorway, their parents began to match the tempo automatically.

Watching their kids romping and rutting in incestuous frenzy, Lorraine and Jack started to fuck with an equal gusto. As if they were magically linked by vision, the adults moved at the same rhythm as the teenagers, jerking together in a standing doggy fuck.

Jack was no longer concerned in the slightest about saving his next spunk load.

He knew that under the tremendous stimulation of spying on the kids, he was going to be able to get his rocks off again and again on this memorable day.

Nancy was starting to cream off.

Her clit was detonating and her pussy was turning out cum as thick as honey. Ricky's prick sank in like a post being hammered into a mud pit. His cock was fiery hot, but now her fuckhole was even hotter, boiling on his prick.

"Shoot up my cunt, Ricky! Jizz in me!" she gurgled, longing to feel his slime squirting into her as she melted in her rapture.

He dipped at the knees and whacked in with a long, rippling, underslung stroke that tilted her tummy up like a lever. His balls rolled along the cushions of the couch, sliding through her slick seepage, then bumped her ass.

Then he jerked his haunches up higher and fed it to her from above, driving down at an angle that ran every inch of his prick across her clit.

Her clit exploded again on the throbbing friction and she cried out with joy.

Ricky kept on hammering in that way, driving her wild as he honed her clit, stropping that sensitive blasting cap with his cock. He was humping faster now, on the cum strokes, his ass a mere blur to the watchers—who were stepping up the pace of their own coupling in accord.

"Fill me up, Ricky! Slime my cunt!"

"It's cummin', Sis! Here it cums!" he wailed.

His cumbags slapped on her curved ass and erupted, and his incest juice poured torrentially into her cunt. He shot off as he plunged in and shot off again as he jerked back, a steady stream of spunk gushing into her melting pussy. His jizz swirled into the tide of her cunt cum and the mingled cream came bubbling from her pussy.

Seeing both of their children creaming off together, Lorraine shoved her round ass back on Jack's flat belly and moaned as she began to juice off.

A split second later, Jack was hosing her with his steaming hot jism, shooting up her so hard that he damned near blew her off the end of his prick.

Ricky emptied his balls off steadily and gradually and his daddy matched the draining rhythm, spurting into his wife each time Ricky flooded into his sister.

Ricky finished and crouched over Nancy, panting like a dog, his cock still burrowed in her.

Jack shot his last wad and hauled Lorraine back by the hips, holding her cunt on his prick.

Nancy squirmed away for a few moments, working off the final spasms of her creaming, and her mother wriggled on Jack's cock, finishing her cumming.

They all realized simultaneously that both of those well-drained pricks were still stiff, both females still horny—and that the fun had only just begun.
