Halloween plays into the family fun in this chapter. Costumes are always fun, especially when they lead to mistaken identity!
Be warned, there's sibling and mother/son incest along with uncle/niece fun. Also a little wife sharing threesome. Not interested? There are other stories for you.
"Why are you such a pain in the ass?!" Bobby shouted at his sister.
"I'm a pain? You're nothing but trouble brother!" Holly spat back. "Why don't you just stay in the city and let us enjoy life?"
Karin buried her head in her hands as her two children stomped off in opposite directions.
Once we were alone I stroked the back of her neck, "Don't worry about it, baby. They'll grow out of it some day."
She looked up at me, "But they're both adults, legally! One on one, they're both friendly and pretty mature, it's just when they're together... I just want them to get along."
I had to admit, it was puzzling. There was just a sibling rivalry barrier between the two kids, both of whom were reasonable young adults when apart. Of course, unknown to each other, both had unexpectedly starred in their mother's most indiscreet and intimate sexual escapades in the last few months.
I sipped on my wine and thought about her problem.
"If there was just a way to wave a magic wand and make them see each other for the wonderful people that they are," she sighed.
An idea began to form in my mind, "Magic wand, huh?"
Karin looked intently at me, "And just what devious idea are you percolating over there, lover?"
I walked over and sat next to her on the couch. Brushing her hair back with my hand, I smiled. "Well, sweet lady, your use of the term 'magic wand' just gave me a little seed of an idea. Because your son has one, and your daughter has shown a mastery of one, at least in my case. I'm just thinking..."
Her eyes widened, "Oh my god, Mike, does everything have to be sexual with you?"
"I'm just saying, let's think about this. Look at how well you get along with Bobby since you fulfilled his fantasy about making love to his mom. And has Holly ever been so well-behaved as she has since she played 'dress up like Mommy'?"
"Well... no..."
"I'm just thinking, if they were to discover how wonderful they were as lovers, if they became lovers, maybe that would improve their relationship.
She was shaking her head, but she was also listening. I knew that her mind was working over the fledgling idea, and waited as she thought.
"I just don't see a way. If either of them sees me, or us, with the other, it'll just incite more of this resentment. And there's no way I'm going to talk them into bed together!"
"Unless..."
Karin turned back to me, brushing a lock of her hair back. "Unless?"
"Unless they don't know who they're in bed with." My mind was spinning through ideas, all of which had me hardening as I pictured Holly's legs spread, her sweet shaven pussy dripping with arousal. Not an unusual condition for me in my sister in law's home.
"That might be a challenge."
"Challenge accepted, with all of the escapades going on in your house this year, seems like a natural progression to me. Give me a couple weeks, I'm coming back in town and we'll have fun with the kids." Then as I pictured my calendar, I had to laugh.
"What?" she smiled
"What's in 3 weeks?"
She thought for a second, and her smile grew, "Halloween."
"Halloween."
This might not be so hard after all, I decided.
Two days before the holiday, we had a rough plan. It seemed do-able, and though there was always a chance that it would fall apart, we were driven by our own lust to make it happen. Our planning always took place right before, or during, or after a hot fuck session. Often my cock would be resting in their mother's pussy, and I would punctuate ideas as I drove deep inside.
It would drive Karin crazy, shooting my cum inside her while describing her son doing the same to his sister.
"Oh baby, when Bobby cums in Holly's pussy, they're going to be so turned on that they'll forget their little feud."
The groundwork was laid for days. Karin had prepared the costumes, we had prepared the deception, and I was pretty sure that we had a good plan. But no plan is perfect. That just made it more exciting.
"So, mother, what are your plans tonight?" Holly asked, looking pointedly at me. I smiled at her, admiring the short skirt of her slutty nun outfit, her thigh-high stockings and garters visible beneath. I was dying to get a glimpse of the panties hidden between those young thighs.
My brother, George, had raised objections to the skimpiness of my niece's costume, but to no avail. The women ran this house, that was apparent.
"Well, your dad and I are just going to hang out with Uncle Mike and hand out candy. We have a little haunted house set up in the garage, so we're going to put on some scary stuff for the kids."
Karin pointed to her witch costume, that with the short black skirt, and the outfits that George and I would be wearing. "Dad will be the grim reaper, and Mike will be the chainsaw killer."
"Ooh, scary," Holly yawned. "Well, have fun, Brenda and I are headed down to the Washburn's, always the best party around."
"I think your brother is planning on being there too, be nice, please?"
"As nice as I can be," Holly replied, just a little sarcasm in her tone.
What Holly failed to notice was that her costume and her mother's were remarkably similar. In fact, below the waist they were to be pretty much identical. Right down to the garters and panties, and black heels.
And she wouldn't have known that her mother had a perfectly smooth pussy for the first time, smoother even than her own. Karin had surprised me with a delicious waxed cunt when I had arrived, just beautiful. When I finished slurping at her for a half hour, she explained that she had let Bobby rub lotion on it for her after the waxing, and since had fed her son between her thighs and felt his lust explode inside her. So, aside from the mother's more generous ass, my sweet sister in law and my sweeter niece were twins below the waist this Halloween.
After Holly had headed out, we put the final touches on the setup in the garage, and went in to put on our costumes. George finished first and was mixing us all drinks. Though we hadn't been flaunting our affair since he had had his wife fulfill his cuckold fantasy that winter night, he always gave us plenty of time together. Karin said that he couldn't wait to fuck her after she had been with me. I was sure he was clued in.
"Damn," Karin fumed.
"What's the problem?" George asked.
"This skirt is a mess, I can't get it right. My garters and panties keep getting snarled." As he started to step towards her, she turned to me, "can you give me a hand, Mike?" Back to her husband, "it's ok, honey, your brother is pretty good with my panties."
A small shock registered with him, but quickly turned to a half-smile as Karin pulled the skirt above her waist, revealing an amazing pair of black lace panties, the panel hugging her trimmed blonde bush, the garment disappearing into her crack as it tapered to a thong that twisted as it rode up between her smooth pale ass cheeks.
"Um, yeah. Go ahead, Mike." He said softly, a noticeable excitement in his tone.
Karin approached me and turned her back. I squatted down to free the lining of the skirt from one of the garter clips, straightening out the costume. Leaning in, I inhaled the delicious fragrance of her pussy and ass, then slipped my fingers inside her thong to straighten it.
Looking at her husband, Karin said to me, "Thanks, big brother. Could you just make sure my thong is centered? I wouldn't want my butthole to show if anybody gets a look up my skirt tonight!"
I slowly pulled the strap from deep in her ass, playing my fingers up and down the valley. "I think you might need a little lubrication here, Karin." I pushed her, making her bend over and put her hands on a chair, then leaned in and ran my tongue slowly from the rear of her vagina up the path of the thong, stopping to wetly tongue her anus before finishing with the panties back in place.
I stepped back. Karin still stood supporting herself on the chair, her ass still exposed, the groove now encasing the thong, and glistening with my saliva. George was in front of her now, leaning back against the refrigerator. "Mike, I think you might need to use something a little bigger to spread that lube, and maybe you can smear something more slippery on me?"
George held his breath in anticipation, Karin waited. I stepped back up to her, grasped the sides of my sweet sister in law's panties, and pulled them slowly over her cheeks, leaving them just below her ass. A tiny drop of drool hung from her labia, it grew as she oozed excitement.
I unzipped my jeans and opened my belt, withdrawing my almost erect cock. Grasping it in my palm, I eased forward until it just touched her cool flesh. A quiet moan of anticipation escaped Karin's lips. I slowly pushed deep between her thighs, then up forcefully against her pussy, feeling the smoothness of her lips, the heat of her core, and the slick lube of her cunt.
I was iron-hard now, and forced myself hard up against her crotch, lifting her to her toes, then dragged my cock back, the shaft sliding between her labia, then escaping from between her thighs, up behind her now, feeling the soft smooth flesh of her ass embracing my slimy head as I did her bidding and left a slick wet streak of both of our lubes up the groove. When I felt the puckered indentation of her anus, I lingered to massage my cockhead around that opening, eliciting a louder groan from her.
Karin lifted her head again and looked at her husband. In a pleading tone, she asked, "do we have time?"
He stood paralyzed. She repeated herself, just a little louder, a little more desperate, "do we have time, do we have time to fuck, George?"
My brother nodded silently. Karin spread her legs wider, bent her knees slightly, opening herself to me.
"Fuck me, Mike. Fuck me quick!"
I didn't need to be told the second time, I was already aligning my cock with Karin's sweet pussy, her lips gapped apart and glistening in the kitchen light. I drove into her, loving the sound of her heavy sigh as I filled her canal, that "Uuuhhh" sound that carried a mix of need and lust and satisfaction. Then as I began to fuck her, driving hard inside, withdrawing only to drive back harder, the sound turned to a pattern "Uh Uh Uh Uh..." The chair squeaked with each thrust as it inched across the floor.
The entire time, she and her husband stared into each other's eyes, both entranced by their mutual fantasy.
"Are you ok, honey?" my brother asked his wife.
"Oh my god yes, Oh George, he's fucking me! His cock is sooo deep inside me! And he's not wearing a condom! Are you going to let him cum in me?"
My brother's mouth moved, but nothing came out.
"Suck his cock, Karin," I ordered her. George looked up quickly, his eyes wide. Karin looked up to him and, after giving me a glance, opened her mouth wide.
I nodded at George, and he stepped forward, freeing his cock at the same time. He was probably harder than I was, he really enjoyed seeing his wife's slut persona in action.
He stepped up, and Karin grasped his shaft, guiding it to her lips. She began to suck at the very tip, and I saw her tongue begin to rim around the edge. George closed his eyes and, unable to control himself, drove into his wife's mouth.
"Uungh!" Karin gagged and through her pussy I felt her body spasm. She instinctively pulled back from the throat-full of cock, but I drove her hard from behind and her husband buried his cock fully into her.
He withdrew, and Karin gasped for breath before he drove back into her, and his eyes opened to watch as he erupted into his sweet wife's throat. Karin had had some experience in handling a face fucking in the year that we'd been lovers, and it turned her on to feel the release of a cock between her lips. I could feel her pussy begin the familiar dance of her orgasm. This was her first time with two cocks, and it was obvious that she was loving it, the good Catholic wife had progressed to being spit-roasted by her husband and his brother.
She gulped and groaned as he emptied his balls into her, holding her head against him. At the same time she bucked back against me, cumming on my cock, her thighs shuddering with her climax.
As her husband pulled his dripping cock from between her lips, she lowered her chest, arching that sweet ass for me to enjoy, and I began to long-stroke her. Her husband just watched, unconsciously stroking his still-hard cock.
I was just approaching my own climax when we heard the doorbell. The trick-or-treaters were here. George grinned, "I'll get that, you two just finish up here." But Karin had already jumped up and spun around, startled and trying to compose herself. That broke my concentration, and she giggled as my rod began to wilt. She leaned over and gave it a kiss and a quick suck.
"Don't worry, we'll take care of this later," she laughed, and ran to the door, opening it to find a porch-full of toddlers. "Trick or treat!" they shouted to the lady with cum on her breath, and soaked thong riding between her legs.
Meanwhile, George had opened up the garage door, revealing the mini haunted house we'd set up for the older kids. It was just a few little passageways with black sheets draped to hide the surprises; a skeleton, some ghosts, and a few other scary props. We had a background recording with screams and moans, and we each occupied a hidden corner to surprise the kids.
As the evening wore down, the visits became fewer and we had more time for cocktails. Karin began to tease more and more, flashing her panties, slipping a breast from her top, sitting on our laps. She told me later that she'd mistaken one of the neighborhood dads for me, and had given him a nice bend-over panty flash. As he stood frozen in surprise, she'd turned and given his cock a squeeze, only realizing her mistake when a flash of light illuminated his shocked expression.
She smiled and confided, "I just might have to give him a little pussy some day, wouldn't be fair to leave him with that tease. Maybe I should go give him a quick visit while we're waiting?"
Another group of kids interrupted her thought, and the neighbor was spared the attack of my sweet sister in law.
Later in the evening, Holly came home, apparently the party was kind of a flop. She seemed to have a nice buzz and flirted with me a little dangerously in front of her parents. I tried to give her a little warning, and she pouted and walked past me, but whispered, "you get enough candy, Uncle Mike?" She reached under her skirt, and brought her finger to my nose. "Don't forget how sweet your little niece is!"
The scent of her had me hard instantly, and I hoped I'd get a chance to get a taste of her as well. She headed to the couch to text her friends
When George decided to turn in early, our plan got easier. He'd be a major obstacle if he was around, even as a cuckold, I doubted that he'd approve of his kids being involved in our deviant play.
A short time later, Holly's brother came in.
He was disappointed in the party as well, but very happy to see his mom, especially dressed as she was. He was a little frustrated that Holly and I were around, no doubt he was craving some Mommy time.
To help us in our scheme, I mixed some heavy drinks for all of us. When Holly suggested shots, Karin and I smiled at each other, now sensing the pieces falling into place.
Our plot to get the kids together wasn't completely planned out, we had to play the hand we were dealt, so we were just looking for opportunity. And doors were opening for us.
I could tell Bobby was hoping that I'd be headed to bed soon, so that he could find a way to get his hands on his mom. When he asked where his dad was, Karin told him that he was in the room over the garage, so he was playing a waiting game.
The kids were pretty buzzed when Karin and I decided that now was our chance. As the two women headed into the kitchen, Karin told Holly that her uncle was wondering if she'd give him a hand in the garage, but remember that her dad was in earshot, she needed to be quiet. She found me in the garage and slipped into my arms.
As we kissed, she rubbed her tummy against my cock, "Mmm, there's that fat uncle Mikey dick I was thinking about."
"Shhh," I pointed up. She got the drift, she needed to keep quiet, her dad was close by. Over Holly's shoulder, Karin smiled at me. In one way, I hoped the plan fell apart. If Holly didn't have her brother's cock in her that night, I was happy to be on deck.
I convinced the drunken teen that I needed some help disassembling one of our displays, and she needed to basically lay across the back of an old couch to reach it. Her upper body was partially concealed by a black sheet she was reaching under.
If she hadn't been so drunk, she might have questioned the whole stupid idea, but... she was.
So, I had her bent over, reaching down to pull a bunch of ties apart, and there was that perfect ass, barely visible as it peeked from beneath the tiny skirt in the black shrouded garage. Could she pass for her mom? I had to believe that anybody lucky enough to see this lovely teen's legs, in black stockings and garters, her ass protruding as she bent over, wouldn't really be questioning who they belonged to.
I couldn't resist, and flipped the skirt up over her back, and eased my face into her panties, intoxicated by the scent of her. She giggled, and again I shushed her. "I'll be back in a minute," I whispered and quickly headed past a smiling Karin into the house.
Bobby was on the couch, and I walked past him towards the guest room. "Hey, your mom wants you to help her with the haunted house out in the garage," I told him. He was up in a flash, "she told me to remind you that your dad's up in the frog, so you need to be quiet."
He grinned at me, "Ok, thanks Uncle Mike."
My nephew was out the door in a flash, following his cock towards what he believed was his mom. He didn't notice me following at a discrete distance.
I slipped out into the garage and hid with Karin behind a pile of boxes as Bobby moved through the garage, and that sweet ass bent over the couch took him no time to home in on.
As I had, the youth eased his face down between his sister's thighs and began to nuzzle at her pussy, barely concealed in the sheer black satin. Holly hummed and wiggled her ass in appreciation. I really expected the kid to rip his pants off and drive into what he believed to be his mom's heavenly slit, but she had taught him patience, and he took his time.
I couldn't see clearly, but it was obvious that he was giving his sister's slick pussy some concentrated attention, licking and sucking, his face moving up and down her ass crack. He pulled the panties aside, and seemed to drive his tongue deep into her, eliciting a gasp from Holly, and she reached back to pull his head to her.
Now he worked up and down, reaching deep between her thighs, and as her body jerked, he must have focused on her clit. Her hand left his head, and tugged on one side of the panties now. Bobby took a pause, and slid the tiny garment down his sister's legs, and they ended up dangling from one of her ankles.
Her brother dove back in, driving his face deep into her, as Holly's legs spread even farther. She began to buck against him, and when he reached down to slide his thumb into her pussy, she began to grunt quietly. His face now moved up and I knew that he was remembering that his mom appreciated the attention of a tongue in her asshole.
Everybody in this family really seemed to enjoy the stimulation of anal, and that lit Holly off. She arched her back, presenting that perfect ass to her brother's tongue, and her hips began to rotate as she climaxed on her brother's face, we could hear her sobbing quietly now.
This was working out better than we could have ever planned it.
Karin had been holding my cock as her children engaged in the incestuous fantasy, unaware of the identity of their lovers, and now she dropped my pants and turned to rub my cock against her panty-clad ass. The smoothness of her ass, the bump across her thong had me oozing pre-cum all over her. Her thumb smeared through it and circled my swollen cock head.
I tugged the thong from her ass and pulled her panties to the side. Her pussy was soaked, and she began to play my cock across it, using it like a dildo to please herself.
The overwhelming stimulation of my sister in law's amazing body, my niece and nephew about to engage in incestuous fucking, and my having been left hanging earlier in the evening, had me crazed. I grabbed Karin's wrist, and dragged my cock up and down her gash, then up farther. I teased her asshole for a second, pressing hard enough for it to start to ease open, but then slid it down to her engorged labia. I played it up and down again, until she had had enough, and drove her lush ass back at me, her pussy swallowing my cock. Now I could fuck this sweet Catholic housewife as we watched her son fuck his sister, believing it to be his mom.
I held there, buried in Karin's pussy once again, feeling like we were permanently joined and palmed her heavy breasts, her nipples swollen as usual. But our attention was really on the scene before us.
As Holly gasped for breath following her amazing orgasm, her brother stepped back and quickly stripped. Holly began to turn around, probably to offer her mouth to the cock behind her, but that wasn't the hole her brother craved, he wanted his mommy's pussy. Little did he know that he was instead about to slide into his little sister's instead. This kid had no idea how lucky he was to have a mom who was not only accepting of him fucking his sister, but had made it happen.
Holly seemed to have no problem with any of this. Her tiny hand reached back between her legs, and Bobby dropped his hard cock into it. As her mom had done, the little teen smeared his lubrication over the head with her thumb, and drew it to the soft wet opening. There was just a slight pause while she played it up and down her pussy, as though Bobby remembered waiting for permission to fuck his mommy, and then Holly eased back, her lips kissing the head, then parting to allow him entry.
Her brother now began to move forward as she moved back, and placed his hands on the back of the couch, holding there as she completely impaled herself on his cock. After holding there, deep inside his sister's pussy, for just a second, he eased back and began to stroke slowly and fully. Holly fell into the rhythm easily, and they began to make love as though they were a couple, familiar with the dance.
Karin later told me that she was tempted to walk over to them now, wrap herself around her son and guide him in and out of his sister's pussy, but she was afraid that the surprise would spoil the perfect synchronicity of their lovemaking. We began to move now in time with the young lovers, careful to remain silent.
The alcohol must have dulled Bobby's senses enough to delay his orgasm, they stroked for fully 15 minutes, the only sounds were the wet slurping of their coupling and a soft pant from Holly. When the tempo began to increase, I knew that the climax was near. I concentrated on staying in reach of my own orgasm, and as Bobby began to grunt quietly, I pushed closer.
Then a giant curveball. Bobby lay across his sister's back, and moved the curtain concealing her from the shoulders up. He wasn't looking at her, he put his mouth to her ear as he held himself buried inside her pussy, pressing her hard against the couch. I knew that he was one stroke away. We strained to hear, and then he said it. "Can I cum inside you Mommy? Can I cum inside your pussy, please?" He was using Karin's trigger but, unknowingly, on Holly.
Karin and I froze. Stray thoughts went through my mind. So close, would this ruin it after all? Were they far enough along that it wouldn't matter if they realized who they were coupled with? What was Karin thinking?
The last was easy, Karin put her hand to her cunt and instantly erupted. Bobby had said the most erotic words in her sexual vocabulary, the exact words that had shoved her off the cliff with him, with me, even at her own hand.
My sister in law came hard around me, and the timing was perfect for me as well. I erupted deep into her, pulled back and drove just a little deeper as I squirted my load inside her.
The real question was Holly. Would the sound of her brother's voice penetrate the sexual intoxication, sober her up and destroy the moment? Would she somehow just think that it was me, talking dirty?
Even as we came together, Karin and I listened in suspense.
The truth was, as Holly later told me, (while we lay in her bed, spooned together with my cock deep inside her), she realized everything at once, like a lightbulb went on; it was her brother's cock inside her, he had given her that amazing orgasm with his mouth, her mother and I must have set the tryst up, and Bobby thought he was fucking Karin. That also meant that he had already fucked his mom, and those words had been spoken before, as he readied himself to spurt his semen into his her.
"It was crazy, Uncle Mike," she laughed as I kissed her neck and held her body to mine. "All of a sudden all of that stuff was so obvious to me, and until then I had no clue!"
"But not only didn't I care, it was the hottest thing he could have said. It was so unexpected and so fucking hot. Bobby had fucked my mom, that visual enough was enough to get me off." she told me. "And he had given me such an amazing orgasm, and I was right on the verge of the next. I wanted him to cum in me, and I really wanted to give him what he needed. I really felt a deep primal love for him right then, and I could see that this would change our relationship forever, not just sexually. I knew that if I said the wrong thing, it would absolutely ruin that amazing moment. So I told him what he needed to hear."
"Cum in me, baby" she whispered back, "cum in Mommy."
Bobby's head flew back as he did what she asked. Not knowing that he was shooting deep inside his little sister, he filled her sweet pussy with his potent cum. He moaned quietly, not wanting to alert his dad, who he believed was upstairs, that he and his mom were fucking, as his body spasmed in orgasmic bliss.
When the moment had faded, he slumped across Holly's back, then she backed and twisted, and he fell into a seated position on the couch. Holly turned and quickly climbed over his lap, one knee on each side of his hips. She grasped his still erect cock and eased it back inside her even as globs of his cum dripped from her spread lips.
She was kissing Bobby as he returned to consciousness, and now we waited for his reaction.
"Holly? Oh my god Holly, holy shit!" She silenced him, kissing him deeply and after a second, he responded, wrapping his arms around her and returning the love.
"But wha..?" He tried to ask the questions which must have been popping into his mind, but his sister put her finger to his lips, and began to slowly ride his cock, her hips moving in a fluid circle above him. I knew that there was no way he'd be softening in that lovely pussy. "Talk later, fuck now, big brother," she giggled, wrapping her arms around his neck.
"How 'bout suck later, fuck now?" he laughed back.
"Well, I do owe you one, "she smiled. "But don't worry, I'm so more than happy to pay that one back."
In the darkness, Karin eased off of my cock, danced her pussy back into her thong, and turned to me. Her smile told me how relieved she was over the whole situation; she wrapped her arms around me and kissed me lovingly. "So smart," she whispered.
"Such good kids," I smiled. "So good together, too."
We turned to look back at the couch, where her daughter sat astride her brother, his cock still filling her tight teen pussy, his cum doubtlessly leaking out around it, dripping down his balls onto the old sofa.
They had spotted us, and both had the same relaxed smile as they peered at us in the darkness. "What's going on over there?" asked Holly.
"Oh, nothing you'd be interested in," laughed their mother.
"Is that right?" the daughter replied. She turned to her big brother and kissed him long and deep, then pulled back and stared into his eyes from inches away. "Not really sure that's true, Mom. Because your son's cock seems to get even harder every time he hears your voice."
She turned back to us, "You know how I know that? 'Cause it's buried so so deep in my pussy. And even with all the cum he shot in me, I think he still wants to cum in his mommy's pussy."
She seemed to jerk in response to him then, and giggled, "See? All I have to do is say 'Mommy' and he's swelling inside me again."
"What do you say, big brother? You still want to cum in Mommy's pussy? Do you have enough to fill up your mommy's cunt?"
The youth groaned and his hips lifted his sister again.
"Hmm, I take that as a yes!" Holly laughed, climbing off of her brother's lap.
She walked towards us, and gave her mother a nod towards Bobby, who sat on the sofa with a full hard-on, glistening in the faint light. "He's waiting on you, Mommy," she said, with an emphasis on the last word.
Karin gave me a glance and I smiled, of course she already knew that it was fine with me, now I could watch her engage in her ultimate taboo fantasy. She approached her son, and knelt on either side of his legs on the couch. He latched onto one of her nipples, and squeezed the other breast as he sucked. Karin held his head to her and began to slowly slide her panty-clad pussy against his slick erection.
"Oh baby, that feels so nice." She cooed. Bobby moaned in response. He gave the other fat nipple the same attention, then lifted up to kiss his mother as no son should.
Holly stood next to me, naked and sweaty, and I moved her in front of me and wrapped around her. My cock was almost soft, but stood out enough to rise between her tiny thighs, and barely touch her dripping pussy. She began to move her ass back and forth, massaging it in the slick remnants of both of our couplings. It didn't take very much of that and I began to swell, filling the little gap between her toned thighs.
I saw Karin grasp her son's hand, and move it around behind her, positioning it on her ass, and moving it inside the crack. His fingers touched her thong directly over her anus, and he began to stroke the thin strip of nylon.
"Mmm, inside now," Karin murmured, and the boy's fingers slid beneath, sliding now on her juicy skin where I had lubricated her earlier in the evening with my cock, tickling across her back entrance.
Karin raised up and stood before her son, holding him by the shoulders. He understood, and leaned to grasp his mother's panties by the sides, and slowly slid them down her hips. Then her reached back behind her again and slipped his fingers beneath the waistband, and moved them down, caressing his mother's ass as he revealed her shining wet pussy.
The panties stopped just above her knees, and she guided his face between her legs as she lifted them, one by one, and let the panties drop to the floor. Her knees spread to allow him easier access, and he was soon nuzzling his mother's most sacred spot.
The sound of him slurping the juices from her pussy became muffled by him burying his face deep within her labia, and now the groaning of his mother began to drown that out. Karin held her son by the head as he ate her out, and her ass bucked in pleasure when he hit her sensitive spots. She came in seconds, her head back, grinding her body against Bobby's face, then shoved him back onto the couch.
I doubt that her son's cock had ever been harder, it stood straight up, as if drawn to the entrance to his mother's womb. Karin had no need to grasp it for guidance, but she did anyway, stroking the glistening shaft as she lowered her flesh to meet and envelop it. There was no pause, they gazed into each others' faces as her body took her son's cock deep into her vagina, all the way inside, until she was seated on his lap. She wiggled against him, and began to gyrate, stirring her pussy with his cock, similar to what his sister had done just minutes before. The garage filled with the sound of their soaked flesh uniting.
Now I was ready as well, and my juicy niece giggled as she pulled a chair close, then bent over with her elbows on the seat. Her perfect little ass shone in the light, slick from her evening of debauchery. I wasted no time sliding between her firm cheeks, wondering how her brother could have mistaken her athletic body for the lushness of her mother's wonderful ass. But I guess there wasn't a lot of room for thinking in his hormone-fueled brain as he molested his sister.
Still watching my girlfriend, my sweet sister in law, riding her son; her hips gyrating and her ass clenching his cock inside her, I began long slow strokes in and out of my niece. Holly's young hairless pussy squeezed me on the backstrokes, and caressed me as I filled her again. Karin turned once and smiled at me, so beautiful with her voluptuous breasts just dripping sweat, her back and ass shining with it. She blew me a kiss, then returned to her son.
They kissed continuously, their hands exploring their lovers. Karin had one hand holding his head to her, the other grasping his as he stroked her ass. She guided him again to her core, and his fingertips brushed across his mother's anus again. Pressure from his mom guided him to concentrate his efforts there, and a groan confirmed her desire as he slid a finger up into her rectum.
I knew from experience what did to her, how her cunt would clamp down, then pulsate as she reached climax, her ass ground against him, urging him deeper still. "Cum now for Mommy," she purred, and he thrust up against her, doubtless spraying his semen against his mother' cervix as he groaned into her neck.
Holly turned to me and smiled dreamily. "How about you, Uncle? Ready to cum in my sweet little pussy?" She reached back and began to lightly tickle under my balls with her fingernails, and my climax hit immediately.
"Oh god Holly! Oh my god yes," I moaned as I blasted inside her. She giggled when I picked her up, holding her back to my chest as I groped her little titties, pinching her nipples as I came. Her feet were planted on the chair, and she drove back against me as I fucked her, feeling her pussy releasing globs of cum which ran down my cock and soaked my balls.
As we finished, I turned Holly to me and she wrapped her legs around me as I made my way across the garage, and collapsed on the couch next to the mother and son. Holly took my cock in her hand and reinserted it, then just relaxed atop me, her face now in my neck, watching her mom and brother.
As they collapsed back against the couch, where he had now filled both his sister and his mother with his cum in just minutes, they relaxed and began to nuzzle each other's necks. Finally, Karin broke the spell. She rolled off of her son, leaving his lap a puddle of cum, and smiled contentedly. "Well, I think it's time you kids got off to bed."
The siblings stood at the same time, and turned to each other, laughing at the absurdity of standing naked in the garage. Then Holly grasped her brother's cock and pulled him close. They embraced lovingly, and she kissed him. Then they gathered their clothes and walked naked out into the kitchen. As Karin and I followed them through the door, we heard Bobby ask his sister, "Your bed or mine?"
Karin turned to me and smiled. "I think they've finally found they have something in common."
"I think you're right, baby. Happy Halloween!"
