"Yeah, go, Mark," she cried, "lick her ass. That'll change her mind in a hurry."
Karen heard the girl's naughty words. She was well aware of that wicked dirty thing Mark was doing, thrusting his thick slick tongue right into her rectum, and she knew she should be shocked and repulsed by the whole scene.
But what she felt was the most stunning delicious pleasure of her whole life. My God, she would never have believed it, but having a tongue up her ass felt fantastically good.
Mark mischievously wormed his tongue around in his aunt's searing tight bumhole, lapping up her pungent juice. He knew she was going crazy with pleasure, and he intended to prolong his bum-tonguing till he blew her mind completely. He vowed that when this night ended, Karen was going to be a changed woman.
Karen knew what he was up to, and she fought against it with the last ounce of her strength and will power. "Nooo," she wailed, "oh, no, Mark, stop… That's filthy, disgusting… Ohhhh, God, please…"
She wasn't fooling anybody, not even her husband. Her lovely face was twisted in a horny leer, her voice husky with pleasure. Stacy and Bill could see the cream flooding from her hair-fringed box, soaking Mark's face. Karen obviously loved having her asshole tongued.
Bill had to hand it to the kid. Once he got over his shock at what Mark was doing, he had to admit it was a great idea. He could imagine how good it would feel to have someone's tongue up your ass, wickedly lapping and thrusting. No wonder Karen was losing her cool.
"Oooooo," Karen whined, "ahhhhh… My God, my God… I…"
Mark's tongue was very deep in her fiery bumhole, and she was trembling on the edge of orgasm. She couldn't disguise her pleasure any longer. She moaned helplessly as the boy probed and licked her aroused asshole. Then, to her intense disappointment, he suddenly withdrew his tongue.
Mark raised his cream soaked face from Karen's twitching wet pussy and gasped, "Turn her over, QUICK."
He wanted to catch her at the peak of her excitement, before she had a chance to tighten up again. Luckily Stacy and Bill obeyed at once, flipping Karen over onto her hands and knees before she knew what was happening.
"Okay, hold her," Mark said, and without losing a second, he wedged the fat purple head of his erect young cock into the tight wrinkled mouth of his aunt's bumhole.
The idea had come to him while he was probing her ass. He really wanted to get his cock into that deliciously tight searing hole. And since she liked his tongue so much, why not his prick? Mark had a lot of experience for a teenage boy, but he'd never cornholed a woman before. It was something he was eager to try.
Karen didn't know what was happening. They flipped her over, her ass up in the air, and then she felt Mark's hot sweaty hands on her hips. She figured he was going to fuck her dog-style, and she braced herself for it, but then she got a surprise.
Mark was pressing the thick hard head of his cock against her asshole, pushing, grunting…
It must be a mistake. Even Mark wouldn't do a wicked thing like that. Karen waited for him to slide his hard cock-head down to her dripping cunt-mouth – but instead she felt it stretching the wrinkled hole of her anus, pushing thickly into her tight asshole.
"Noooo," she screeched.
She tried to crawl forward, to get away from him, but Bill and Stacy held her firmly in place. She felt Mark's long thick cock stuffing her tiny bumhole, pushing deep into her bowels. To her utter surprise and shock, it felt good.
"N-no, no," she whimpered, "take it out… You mustn't…"
But her protests were feeble, and when Mark began moving his cock in her, fucking her tight little ass, reaming it, she lost control of herself. The pleasure was just too great. She creamed helplessly and began to move her hips in time to his strokes, wanting him deep, deep inside her.
"Ummm," she whined, "oooo…"
"You like it, Auntie?" Mark panted. "Feel good?"
"Oh, God, yes," Karen whimpered. "Fuck my ass, Mark, darling… Don't stop…"
The others breathed a sigh of relief. At last Karen was one of them, freely admitting her lust, joining in the fun. It had been quite a struggle, but it looked as if they'd destroyed her inhibitions for good.
"You can let go of her tow," Mark chuckled. "She's through fighting."
Bill and Stacy let go of her shoulders, and Karen stayed right where she was, grinning lustily, moving her hips in horny jerks to take Mark's thick meat deep into her nipping asshole.
"Yes, darling, yesss," she purred, "keep doing it… It feels soooo good." Stacy dived for Bill's cock. She'd been wanting to suck it ever since they came into the bedroom, but she'd had to help with Karen. Her little twat was blazing and wet with need, and she was wildly horny from having to wait so long. It'd been torture sitting there and eying her uncle's fantastically long prick, unable to play with it.
So she didn't waste time. She shoved her face into Bill's lap and greedily stuffed his long sausage-like prick into her mouth. She began sucking on it ravenously, tickling it with her tongue, bathing it in her steamy spit.
"Hey!" Bill yelped. A look of horny ecstasy came over his face. "Oh, Christ, yes, honey," he moaned, "suck my cock… Yeah, yeah…"
Through glazed lusty eyes Karen saw her adopted daughter sucking Bill's prick, saw Bill getting a superb hungry blow job from another woman. For a second she blazed with jealousy – but then it faded. Those feelings were all in the past. She had Mark's marvelous young prick jerking deliciously in her asshole, so she didn't have to be jealous.
It was a very liberating feeling. She and Bill could fuck these handsome youngsters and still love each other. That was certainly an improvement on their boring marriage. In fact she felt glad for Bill. She grinned at him, and he winked at her. "I bet that feels great, doesn't it, darling?" she said to him.
Bill nodded blissfully. "It sure as hell does," he sighed. "You think you could learn to do this, honey?"
Mark chuckled. "She already gives a damn fine blow job, Uncle Bill," he said. "She's sucked me off a few times."
Karen blushed, but Bill just grinned. "That's good news," he said. "I'll have to sample her work real soon."
He felt as loving toward Karen as she did toward him. He watched her lovely face as Mark buggered her, gad to see her so ecstatic. She clawed the bed in her excitement, moaning without shame.
"You seem to be enjoying yourself," Bill chuckled. "Does that feel good, honey?"
Karen sighed deeply. "Oh, Bill," she said, "I can't tell you how good it feels. It's just fantastic. We've got to try it sometime."
"You can bet we will," Bill said, "first chance we get."
He didn't say much more after that, because that little devil Stacy was sucking his cock so hard and fast, it was blowing his mind. His prick was erect and straining now in her mouth, butting her silky hot throat, and his balls were rubbing her chin.
"Yeah, baby, yeah," he chanted, "stick that meat… I'm gonna come, honey, can't hold it back…"
Karen watched as Bill howled with pleasure and began shooting his steamy load into Stacy's eagerly sucking mouth. The girl expertly swallowed all of it, not missing a drop, her throat working hungrily. She sucked Bill's squirting dick till he was whimpering with joy. Karen noted her niece's technique and vowed to imitate it.
Meanwhile Mark was working his swollen dick harder and harder in her asshole, and in another moment she felt herself starting to come. She moaned blissfully as her body began to spasm. Mark felt her already narrow asshole closing tightly, wetly, around his swollen cock.
"Aw, shit, YEAH," he yelped, "I'm coming! Ahhhhh…!"
He shot his steamy jism deep into her bowels, and Karen took it happily, moaning, sighing. When he finally rolled off her, she blushed and laughed. She certainly had behaved shamelessly tonight – but it no longer bothered her.
