Sarah felt heavy. And couldn’t see anything. Then she removed a hand from her face and saw that there were a bunch of bodies sprawled on her bed. She checked her iPhone clock—9:37. Gosh, it’s late. But it’s Saturday.
She stretched and realized she was naked. Then she looked around and saw her children all sprawled around her. Naked. All the activities of the previous night came rushing through her with feelings. Guilt, fear, and shame were not there, as she only felt love, lust, and desire for her children. Was she now so corrupted?
She kept stretching as she fondly saw all her children. She could still feel, see, and smell everything from last night. Hell, she could even smell everything now. Sarah smiled—then she could feel it.
Emma was up, her fingers making up-and-down lines on her mother’s thigh—lightly tracing a path to her pussy. She looked up to see her Mom awake and smiled enigmatically. Then they looked at each other as Emma mouthed, “Good morning.”
Jason was at the foot of the bed, half-hard already and half-asleep—the boy always woke up ready. Lily, sweet, innocent Lily—was she innocent?— was curled against her brother’s side, her lips parted in sleep as she made soft snores.
The children had fallen asleep in the room since Mark was traveling and was not expected to come home until later that weekend.
Sarah bit her lip as she remembered her husband.
“So,” Emma said, rolling onto her stomach, her bare breasts pressing into the mattress. “Dad.”
It’s as if she read Sarah’s mind. When Jason heard the word ‘Dad,’ he got up, rubbing his eyes open. His stirring caused Lily to get up too; as she looked around drowsily, she remembered where she was and, with wide arms, greeted everyone cheerily with “Gooood Morning, Fam.” This cheerful greeting caused all of them to laugh and hug her tight, their naked bodies pressing against each other.
Emma tried again. “So what do we do?”
Lily: “About?”
Jason: “Dad.”
Silence as they looked at each other—the word hung in the air.
Sarah sighed, running a hand through her hair—her nervous tic. “Your father has ... kinks,” she admitted. She was practically blushing, even after what they did last night. And even after the fact that they were all naked. “He loves watching me...”
Jason interrupted, “So do we!”
Emma smacked his arm. “We’re being serious here.”
Jason: “Owww. So am I,” as he stared at her mother’s breasts.
Sarah smiled and continued. “He loves watching me, sharing me with others, and swinging with me. But incest? I don’t know. He’s never said anything.”
Emma, always the perceptive one: “But?”
Sarah was quiet
Emma: “There is a but.”
“But,” Sarah conceded, a sly smile creeping across her lips, “he’s always been very close to his sister Mary.” Her gaze flicked to Lily. “You remember Aunt Mary. The way she’d sit on his lap at barbecues, let him fix her drink...”
Jason started to question, “Do you think that Aunt Mary and Dad—”
Sarah replied, “I don’t know for sure. I can’t be certain. Until today, I never believed I would engage in incest. But I think, after what happened yesterday, anything may be possible!”
Emma said, “Wait, didn’t he say he was visiting Aunt Mary today before coming back from New York?”
Jason groaned, playing with his already hard cock. “Fuck. You think...?” He left the part unsaid.
“May ... be. But even then, I think—no, I know—if he did have the incest bug, he would want to be closer to home,” Sarah said, looking at Lily. “Maybe he could be convinced like I was,” continuing to look at Lily and putting a hand on her thigh.
Lily’s breath hitched as she started to say something.
Emma cut her off sharply, “I think I’ll seduce him. Aunt Mary or not.”
“NO,” Lily sat bolt upright, sheets falling, breasts jiggling. “I’ll do it.”
Silence as three pairs of eyes bore on her.
Emma suppressed a smile but feigned a single raised eyebrow. “Excuse me, little one?”
Lily stared back at Emma with her blue, determined eyes and said with a confident smirk, “Daddy can’t say no to me. I’m his princess,” she pouted.
Sarah smiled, but her fingers were drifting between her legs. “Oh.” This incestuous talk of seducing Daddy and also seeing her kids naked was making her, well, very horny. And apparently, it was making them horny too. Jason was stroking his stiff cock.
Jason tickled his younger sister. “Princess, huh?” He grasped Lily by her hips and hauled her petite body onto his lap—Lily helped him by allowing this easily. Jason’s cock was currently nudging against her bare pussy. “Say that again,” he teased her and grinned.
Lily’s pussy was doing an open-close motion against the tip as if trying to suck it in as Jason rubbed the head of his cock against her pussy.
“Daddy’s little princess,” she whispered, mixing sexiness with innocence in such a dirty way. She started grinding down on him, pushing her pussy on his dick. “His perfect girl—ohhhhh!”
She slid into him in one deep push, making her shout, “Yessss. Yes, yes, yes.”
Emma didn’t wait anymore. She crawled forward, planting her lips on her mother’s mouth in a hungry kiss. Sarah melted into it, her tongue tangling with Emma’s as their breasts pressed together. “You’re evil,” Emma murmured, putting her tongue out so Sarah could suck it. “Putting those thoughts in her head.”
Sarah paused and grinned. “Me? Innocent old me? I did nothing. I said nothing. But you, I know, have a filthy tongue.”
Emma laughed, then planted kisses as she went lower—lips, chin, neck, breasts, nipples, stomach, and navel—before arriving between her mother’s thighs. She stuck out her tongue and made a slow, deliberate lick of her pussy.
She looked up; her mother was charged up. Emma chuckled and said, “Let me show you how filthy my tongue really is.”
Sarah groaned as she felt Emma’s tongue doing wonders in her pussy. Her fingers held Emma’s hair, guiding her daughter. “YESSSS—oh yes, just like that, baby—fuck!”
She enjoyed sex for her fans, but she relished it for her kids. Unashamed, unapologetic, incestuous sex.
Jason, meanwhile, lifted Lily easily and kept bouncing her on his cock, his grip on her waist light so as not to hurt her. “Dirty girl,” he panted. “You’re thinking about Dad fucking you?”
Lily whimpered, nodding as she continued to bounce on him. “Y-yes! He—oh God—he’d touch me just like this, fuck me just like this. I’ll fuck him just like this.” Lily bounced extra hard on Jason’s cock as he groaned.
Hearing Lily talking about fucking Dad made Emma moan with her mouth on her mother’s clit, her finger inside her pussy. She was soaking the sheets beneath her while holding Mom’s ass for leverage. Then inspiration struck her.
She licked down the folds from the clit and kept going lower and lower as she lifted and pushed Sarah’s legs towards her shoulders. She placed a tentative, flicking tongue at Sarah’s tight little asshole.
Sarah shrieked. “EMMA!” The younger siblings also stopped and stared at what had just happened.
Emma smirked, now swirling her tongue in a slow circle around Mom’s ass. “You like that in your videos,” she purred, pressing the flat of her tongue against the sensitive rim. “Begging for it.”
Sarah trembled and then smiled. “FINE! Yes! Please!”
Emma didn’t need to be told twice—she rimmed her mom and played with her clit with her left thumb. She glanced up, catching Jason’s gaze, then deliberately curled her right index finger and inserted it into her mother’s ass.
Sarah shrieked, her back lifting even more, giving Emma more access.
Jason’s rhythm faltered. “Fuck,” he said as he stared at Emma doing unbelievable things to Sarah. Lily couldn’t take it anymore and came with Jason’s cock in her pussy, his hands on her clit, and the depraved sight in front of her.
Emma crooked her fingers inside Sarah’s ass, twisting them just the way she’d seen Mom’s costars do. Then, grinning wickedly, she pulled them free, holding them out to Jason. “You want a turn, bro?”
For a heartbeat, no one moved.
Then Lily, breathless and flushed, slid off Jason’s cock, whispering, “Do it.”
With a fluid, practiced motion, Sarah curled her spine, drawing her knees past her shoulders until the soles of her feet faced the ceiling, holding herself open and exposed in that perfect arch. Jason crawled to Sarah, his firm cock eager; he knelt in front of his mother and positioned his cock at her inviting asshole.
Jason pushed his cock into her tight ass as all 3 siblings saw it disappear inch by inch into their mother’s bleached asshole. “OH MY GOD—JASON!”
Emma licked her lips, watching her brother’s cock disappear into their mother’s ass. Then she turned to Lily, pulling her into a filthy, passionate, and hungry kiss. “You encouraged Jason to do it,” she murmured against her lips. “Now get down there and help Mom.”
Lily, ever the princess, went down slowly to lie between Mom’s legs, her tongue darting out to lap at her mother’s dripping pussy, while Jason continued to pound.
Emma, meanwhile, circled behind Jason and caressed his ass.
“Wha—?” Jason started, then groaned as he felt Emma’s tongue on his ass crack. It startled him and caused him to thrust harder inside Sarah.
Sarah wailed, her entire body clenching around Jason’s cock. “EMMA!” screamed Sarah and Jason in unison.
Emma only laughed to herself and replied, “Hmm hmmm,” licking deeper into Jason’s ass.
