She was anxiously anticipating getting an asshole full of hot cum.
Ron lunged, throwing all of his weight behind his cock. He immediately slithered all the way through the moist, narrow heat of the woman's snapping shitter. Her asshole clamped, down on him like a vise, and he loved it.
He pushed again, even though he was all the way in, and felt his drawn-up nuts rubbing her rubbery ring. This was it! He was fucking an asshole! He backed out until the ridge of his cockhead caught on her nipping ring and then shoved forward again. Heidi groaned and hunched her ass back at him, making the plump, white mounds quiver.
"Oh, yessss!" Heidi groaned around Dan's balls. "Keep doing that, keep fucking my ass! Fuck it just like you did your mom's cunt, honey! Lean over me, now, grab my tits, use 'em like handles!"
Laura moaned and spasmed around the cock in her cunt, part of her mind listening to the obscene dialogue between her son and the older woman. The mental images were just too exciting for her to bear, and she tried to see what they were doing.
Dan saw the mother's interest and decided to investigate her asshole. He slipped one hand under their bodies and poked a finger into the wet crack that Karen had used before him. Laura grunted with happy surprise as she felt her asshole being rubbed again. Then the man goosed her, and she arched her back to his cock. She liked the feel of his finger driving in and out of her tight ring while his cock pounded her cunt.
Ron, meanwhile, was fighting back his come. He wanted the ass-fuck to last forever. This was for him! Neither Karen's hot little mouth nor his mother's greasy, rippling pussy had felt this good. This was the tightest, just like his own fingers when he masturbated, and it was boiling hot! Her asshole was lively, too. The large, strong muscles kept munching on him, squeezing and milking him, snapping at the base of his cock or the neck, depending on the stroke.
And her tits were so big his hands just sank into their wide curves. He thrilled to their dangling weight and the heat and hardness of their nipples as he clutched them while drilling deep into the boiling cauldron of her ass.
She hunched and squirmed her impaled butt back at him as his boring cock sent ripples of pleasure through her shitter to her cunt. She gasped and screamed and gulped Dan's nuts into her mouth as her climax struck, then felt the twin orbs pulled free as her nephew backed out of the woman's cunt all the way.
Laura felt Dan's cock leave her cunt and felt like crying. She'd been coming almost continuously ever since her son had fucked her, and she didn't want it to end, ever. But then she felt him move Karen aside and double her legs up against her wobbling jugs. Now her swollen cunt and distended clit thrust up into the air, as did the rose-like dimple of her asshole. She began to suspect what he was about to do.
Dan grinned as he guided the huge head of his cock to the woman's waiting, helpless asshole. The little pucker was winking with anticipation as he pushed forward, and then he hissed as her tight, muscular ring began stretching around the bulb, pinching it. Laura groaned with combined pain and lust.
Karen scrambled the rest of the way off the couch and squatted down beside Dan's legs to watch what was going on. Her fingers found her mother's cunt and started playing with the loose lips and clit as she stared at Dan's disappearing cock.
Dan was leaning on his prick, now, and it threatened to bend under his weight and Laura's tightness. Then the head slipped in. He felt her bung snap around his shaft and heard Laura pant with ecstasy. He had her now. The thought of fucking this helpless mother while her kids and his aunt watched made his cock even harder. He jammed the remainder of his shaft up her hot ass.
Laura felt a terrific stretching and burning around the sensitive lips of her hung, but the filling of her shithole was more than pleasurable. She didn't have words to describe it. She felt her rear tunnel gripping his dick, felt her muscles rippling around it as if trying to shit him out, and then he began fucking her guts, turning her rubbery ring in and out with every thrust.
"Aaaghhhh! Uh, uh, uh, uh…" she grunted everytime he socked his greasy cock back into her clinging asshole. She felt her dark tunnel spasming around his twitching cock and threw her arms around him. Her knees pressed painfully into her large tits, but she didn't care. She was about to come a new and different way. The flashes of fire were spreading from her shitter to her cunt, and from her clit to her asshole, and every which way in between. Even her nipples were tightening and burning!
"Uhhhhh…" she moaned, trying to lift her ass to meet his buggering. "Give it to meeeeee!"
Dan pumped her asshole furiously, stabbing his prick into her greasy, hot shitter again and again. Just knowing that this was a virgin asshole he was fucking made his pleasure increase, and he couldn't help comparing Laura's ass to his aunt's.
Heidi's had been great, no doubt of that, but her butt hadn't been this tight and hot! Maybe he shouldn't have hosed her out with the enema, first, maybe that had made her too slick and loose. He wondered how Ron was finding his aunt's shitter.
But he couldn't keep pumping his swollen cock in and out of Laura's stretched asshole for much longer. It was just too tight and hot, and the muscular action was driving him crazy, working as it did on the entire length of his shaft. He focused his eyes on the fingers flying over the cuntlips a few inches above his working cock.
Laura was ready to climax again. Karen had her throbbing clit between the first finger and thumb of one hand, and the other hand was stroking rapidly in and out of her raw-nerve cunt.
"Aghhhh, I'm coming!" she howled, bunching as Karen tweaked and rubbed her clit and Dan slammed his massive cock to the hilt in her clamping bung.
Dan felt the thrashing mother's tunnel lining close over his cock and began spasming. He closed his eyes and let his body collapse on her, forcing Karen away. His balls contracted and he howled into the space between her knees and squashed tits.
Ron heard his mother and the stranger grunting and wailing, and saw a burst of white, creamy jism ooze out of the stretched red ring around the man's cock. The sight was too much for him, and he lost his control. He hammered wildly into Heidi's tight, winking shitter as the jets of his cum burst from the tip of his prick. He hosed out the woman's bowels as his hands mauled her big boobs, bruising them.
"Yahhhh-huhhhh!" Heidi grunted, shuddering as she climaxed, too. She felt the teen's cum squirting into her asshole, felt the thick, sticky jism filling her and overflowing the tender, pleasantly sore lips of her bung.
Laura's head lolled on the cushions, her mouth slack and her eyes closed. She'd fainted from the intense pleasure of her first anal orgasm combined with the thrills brought on by her daughter's clit-twanging.
Dan was wordless for a change. He'd never come so strongly, nor had he affected a woman this way, before. In a way, he felt as if he'd had some sort of religious experience. He gently eased his limp cock from Laura's oozing bung, watching her slackened muscle close after him. A trickle of whitish jism drooled from the pouting asshole.
"Hey, Karen," he called. The girl looked at him. He pointed to her mother's exposed asshole. "You still hungry? I don't think she'd mind if you took advantage of her while she's sleeping."
Karen looked at the drops of cum around her mother's pink bunk and at the shiny cunt juice smearing her asscheeks and inner thighs. Above, her gaping pussy was shining sexily, looking mouth wateringly sweet. She didn't hesitate. She dove right in.
Ron was still in Heidi's asshole. Even though he'd come and was completely limp, he wanted to keep his pecker in that tight, steaming hole a while longer. She obligingly kept her bent-over position, sighing from time to time as her asshole involuntarily spasmed around his cock. His hands were working her heavy tits over more gently, now, and he was paying more attention to her sensitive, thrusting nipples.
