Kim walked through the department store with a flushed face. She was horny, and wished she could feel guiltier about it than she did. But since fucking both her sons, she seemed to need a fat cock stuffed her cunt more and more often. She glanced quickly at Mary, wondering if the scent of her pussy had readied her daughter-in-law yet. To think, Kim mused while pretending to examine a dress, that her own sons had reawakened her sexuality at age forty!
"Are you all right, Kim?" Mary asked, breaking in on the woman's thoughts.
"Huh? Oh, of course, why?"
"Well, you seemed so far away, and you looked so unhappy."
"Oh, I'm fine. Just daydreaming a bit, I guess."
"If you don't feel like shopping any more, we could stop for lunch," Mary suggested.
"I'm not really hungry, but I could use a drink. How about you?"
"Well," Mary looked a bit dubious, then decided that one or two drinks couldn't hurt her. "Okay," she smiled. "That'd be nice."
A few hours later Kim mumbled, smacked her lips, and sighed sleepily. She knew she was on her back, and one hand was between her warm thighs, cupping and rubbing her itchy pussy with gentle, rhythmic insistence. She drifted off again for a while, and when next she woke up, her hand was still holding her wet cunt. Her other arm was numb, trapped by some weight. Wearily, she turned her head on the pillow and saw Mary stretched out beside her on the bed. Her daughter-in-law looked like a woman in need, even in her bra and panties. She was moaning and lurching slightly and onto her hands was pulling at the waistband of her thin panties.
Vaguely, memory returned to Kim. She and Mary both had too much to drink at some hotel bar, and one of them had got the bright idea of resting somewhere for a while. Kim couldn't be sure but he thought Mary had registered for the room.
"Mmmmhhh," Mary sighed in her sleep, and ran her tongue over her dry lips.
Kim couldn't help noticing the girl's well-filled bra. Her tits were really big, and the lumps of her nipples showed through. But what was especially interesting from Kim's point of view was the way Mary kept pulling her panties. More and more of the material was sinking into the split of Mary's plump pussy. Soon, one pink, hairy cunt-lip popped free, and then the other. It looked as if they were biting down on the thin strip of cloth, and Kim felt that old itch returning. She remembered how she and Nancy had played with each other's tits and cunts when they were girls.
"Mary?" Kim whispered, feeling her clit tighten. She cupped one of the girl's thrusting tits. Even through the bra it felt soft and warm. She slid her hand under the cup and massaged the spongy globe, letting the hard nipple nestle in her palm. She licked her lips.
Then she stroked down the soft mound of her son's wife's belly and gently ran her fingers back and forth over the exposed, hairy cunt-lips. Mary groaned, and her hands released the waistband of the panties and fluttered aimlessly. Her legs spread wide and she hunched a bit.
"Ohhh, Bill! No, not again," Mary mumbled. Kim froze. Bill? It couldn't be! Mary was just dreaming or something.
"What about Bill?" Kim whispered, lifting her hand from the girl's cunt-lips.
"Ohhhh, no, Bill, not in the ass, please. Put it in my pussy, it's sooo hot."
Kim sank back and rested her head on the pillow. So Bill, her son, had fucked his brother's wife. My God, was everyone in her family fucking everyone else? If Jack ever found out that Bill had… No, she wouldn't even think about it! But then, what if Mary found out that Jack and Bill had fucked their own mother! Oh, everything was getting so complicated, and she hadn't meant for any of it to happen!
"Ohhhhh," Mary moaned. "Put it in, please, I need it so bad… couldn't tell you before…"
Her voice drifted off, but her hands went back to her panties, rubbing and circling as her hips lifted high enough to expose the plump cheeks of her soft ass.
Kim found herself staring hungrily at the girl's half-exposed cunt. It looked so pretty, so sexy. Daringly, she grabbed the panties and slid them down her daughter-in-law's hips. Then she eased her fingers into Mary's pink, wet pussy, just below her throbbing clit.
"Ummmm, yessss," the girl hissed. Her tits wobbled in their cups, and Kim pushed them up until they rolled free. They were soft and warm. Kim's left hand jiggled and squeezed them lovingly. She bent and kissed the big fat nipples, then sucked in first one, then the other. She licked the white mounds until they glistened with saliva, all the while stroking the girl's tender cunt.
Kim bent down to watch her fingers. Mary's plump, pink pussy-lips were pouting wetly, and the scented pink folds made the mother's mouth water. Except for the all the dark hair, they weren't all that different from Kim's memory of Nancy's cunt-lips. But she and Nancy had never used their mouths on anything but tiny nipples.
Mary's clit was bulging from beneath its hood now, darker in color than the rest of her cunt-flesh. The red cunthole was nearly steaming with heat, and the sheet beneath Mary's ass was soaked. Kim eased one finger into the narrow, wet cunt.
"Ummmmm," Mary sighed, hunching against Kim's hand, and Kim felt the hot pussy squeezing her finger.
Mary's big white tits were heaving on her chest as her mother-in-law, shoved another finger alongside the first. Then Kim's thumb pushed down on the girl's straining clit, which slithered free. The thumb chased after it, causing it to slip and slide all over the place. Mary went wild.
"Eeeghhhh!" the girl screamed, her slender body shaking convulsively. Her hips lifted and circled as a series of orgasms rippled through her. Then she collapsed, quivering and babbling incoherently.
Kim, however, was hotter than ever. She yanked off her bra and knelt over the girl. Her white tits hung low, their tight-nipples throbbing and extended. She aimed one at Mary's mouth, shoving it between the slack lips. The girl took it without question. Then Kim bent her head to Mary's crotch.
Mary felt her clit being stroked by something soft, warm, wet and wonderful; she gasped and writhed as her loose, warm cunt-folds were sucked in, licked and nibbled with greater skill than Jack had ever shown.
"Arghhhh, no-o-o-o! Ahhh, ahhhh, ahhh!"
Mary's already muddled senses reeled as her hips swung with another orgasm. Hands were gripping the cheeks of her ass, dragging them apart, and then she felt a tongue – it had to be a tongue – worming through the crack of her ass, stroking the hot crease and tapping at her tender, sensitive asshole!
She forced her eyes open. "Ohhhh!" she gasped, for her first sight was of Kim's ass hovering over her face, the full, white asscheeks quaking and, below them, Kim's plump, drippy cunt-lips hanging open, surrounded by dark hair.
"Uhhh!" Mary gasped again, for Kim's tongue had stabbed her asshole, piercing it, laying deeply into the smooth, tight shitter. Mary shuddered and mewled as the warm, wet tongue stroked in and out of her erogenous shit-chute. Bill had been the first to make her aware of the great pleasure to be derived from tormenting her asshole, and now she couldn't resist it.
"Ohhhhh, Kim," she groaned, her big tits wobbling heavily on her chest. "Ohhh, it's good, it's good – I love it! Yes-s-s-s, lick my asshole, stick in me! Oh, yes-s-s-s!"
Reaching down, the girl spread her asscheeks wider, stretching the rubbery ring of her ass-lips and exposing some of the pink inner membranes. Kim forced her tongue past the muscular ring and into her daughter-in-law's dark ass-tunnel.
Kim's plump asscheeks were approaching Mary's apprehensive face. The older woman's hot, musky-smelling cunt pouted and drooped, and Mary wasn't sure she'd be able to do what her mother-in-law obviously wanted.
But the girl wasn't given a choice. The cunt abruptly dropped, and Kim was rubbing herself off over Mary's lips and nose. Hot pussy-juice smeared the girl's face as she hunched back and forth.
"Mphhhhh!" Mary cried. "Mmmphhh!"
Kim pulled her tongue free of Mary's puckered asshole and circled it with her stiff middle finger. Slowly she eased the finger into the heat and softness of the girl's asshole. Mary sighed and hunched as her ass was penetrated, and when Kim sucked in her clit again, she was lost to lust.
Kim felt her daughter-in-law's tongue part her cunt-lips. She gasped and moaned into Mary's crotch, running her finger in and out of the humid tightness of the girl's ass.
Opening her eyes, Mary saw Kim's asshole puckering invitingly above her; she reached up with her tongue to give it a lick. Kim whined and jumped, but settled back down, asking for more. Mary stroked the raised ridges of Kim asshole with the tip of her tongue, then drilled into its hot center. Soon both women were cumming, gasping and groaning into the other's spanning cunt. Again and again they fingered and tonguefucked each other.
The mutual fires in their hot cunts blazed intoxicatingly; their entire world consisted of soft, slippery tongues and talented fingers. Hours later, exhausted by countless orgasms, the two hot-assed females writhed their sweaty bodies together in the blissful afterglow. They panted into each other's mouths, lying in each other's arms. They smiled and purred contentedly, like cats.
Mary wiped tears from the corners of her dark eyes. "I didn't know it could be anything like that," she said softly.
"It was good, wasn't it?" Kim said, stroking the girl's white tits.
"Good? It was the most exciting experience of my life!"
"Better than Bill?" Kim asked casually.
"You know?" Mary exclaimed. "Oh, Kim. I don't know what to say. I didn't mean for it to happen."
"Was he good? Did you enjoy it? That's all that matters."
Mary squirmed as Kim caressed her. "Yes," she admitted, "he was good. Better than Jack, I think, except Jack's never done it in my… my behind."
"In your ass? He fucked your ass?" Kim asked, almost enviously. "Didn't it hurt?"
"Just at first."
Kim thought about her son's big cock, and tried to picture it fitting into the snug asshole she'd been fingering half the day. Assholes must stretch even more than cunts, she decided. The horny mother remembered how Bill had licked and lapped her asshole, and how thrilling it had been to feel Mary's slender finger goosing her. The idea of ass-fucking was beginning to appeal to her.
"Give me a kiss," Mary begged, holding out her arms. Kim knelt between her daughter-in-law's spread legs and pressed their sopping cunts together. Both women groaned as their slick clits slithered against each other.
"How's that?" Kim teased, swinging her lips a bit.
"Ummmmm-m-m-m, nice, but that's not what I meant, you know."
"I know," Kim said, lowering herself until their tits met. She let her lips go soft and kissed Mary's parted mouth, slipping her tongue inside to meet the girl's.
"Mmmmm." Mary groaned, and wriggled her hips. She too was heating up again. Kim pulled away.
"We've got to stop," she said, her face a bright red. "We're late already."
"Ohhhhh," Mary pouted. "I thought you were going to teach me to do nasty things with my mouth and tongue?"
"Huh! You know as much as I do now. I haven't done anything like this since Nancy and I were kids."
"You're kidding. You and Nancy? Wow, I'd like to see that!"
"Well, aren't you the swinger all of a sudden!" Kim laughed.
Mary grinned sheepishly. "Deep down, I've always wanted to be what Mom used to call a bum – you know – someone who fucks when they're horny, even if they're not married."
"Jack's in for a pleasant surprise, I think," Kim said.
"Oh. Do you think anyone will suspect? I mean, do we look guilty or anything?"
Kim laughed again. "It's not something that shows, dear."
"Jack'd kill me, I think," Mary said thoughtfully.
"And if he ever found out about Bill…"
"Jack's got a guilty conscience too, Mary," Kim said suddenly.
"What do you mean? You mean he's – he's cheated on me!"
"Listen, I think we're close enough now for you to handle this. You're certainly in no position to make any sort of moral judgment, anyway."
"Yeah," Mary smiled wryly, thinking of their wonderful afternoon. "Go on, tell me. I won't say anything to Jack."
Kim took a breath, then related how Jack had mistaken her for Mary, and how her own instincts had betrayed her. Mary was wide-eyed and red faced by the time the story was finished.
"Wow," she said finally. "That sounds like Jack. He's always trying to lick my cunt. And fucking your tits – Jeez, I've never even considered that! Guess it was too dark for you to see what it looked like when he came, huh?"
"You're not a bit upset, are you?" Kim asked wonderingly.
"I know it's strange, but I'm not. If it were some other woman, I probably would be. But I've always suspected he had the hots for you and, well, since all this happened, what's the big deal?"
"Well, at the time it bothered me quite a bit."
"I can imagine. All that guilt about incest, huh?"
"There was more to it than that. Mary, Bill and I have been fucking since that day, too. It started with him. I was rubbing his back, and one thing led to another, and before I knew it I was playing with his cock and balls. That's why I was so shocked by what Jack did. I was still all messed up over Bill."
"My God, Kim, you've got a problem. You know, both of them are going to want to keep fucking you. And I know I want what happened here today to happen again too."
Kim sighed heavily. "What am I going to do? I don't want to come between you and Jack, and now that it's happened, I don't want to give Bill up. Or you."
"You're bound to be caught sooner or later," Mary said. "If Jack catches you with Bill, and you've cut him off, he's going to be furious."
"And if he catches you with me, same thing."
They looked at each other worriedly. Mary reached out and lifted her palm between Kim's thighs. "I don't want to give this up," she said, letting her mother-in-law's loose, pink cunt-flaps rest on her open palm.
"What do you think about bringing everything out into the open?" Kim asked. "Frankly, I'm scared."
"Jack would be mad that Bill beat him to you, and he'd be jealous of our relationship, I think."
The two nervous women finished dressing and left the hotel. The curious stare of the clerk followed them. But his eyes quickly dropped to their plump, jiggling asscheeks. He licked his lips and looked around before rubbing his crotch.
