“Oh, Daddy,” Sidney said as her father finally entered her. It felt so perfect, like a piece of her that had always been missing.
“OK, hold there,” Mom said, “Smile for the camera. Very nice!”
Dad began to slowly drag his dick through his daughter’s depths. He moved slowly at first, and Sidney found her cunt clasping on to his cock tight, like it couldn’t bear to let him leave.
“Fuck, that’s good pussy,” Dad said, “Princess, you’re amazing.”
“Thanks, Daddy,” Sidney said, pleased.
Dad reached up and grabbed her tits. He twisted her nipples, hard. But what should have hurt only felt incredible. Like a livewire straight down to her sex. Dad’s pace increased. Soon he was snapping his hips hard with every thrust.
Click click click. Mom took pictures. Slap slap slap. Dad fucked his daughter.
Dad’s increased ardor pushed Sidney’s pleasure. But she didn’t think she was going to cum. She could see her peak in the distance, but it wasn’t nearly close enough. She reached down and rubbed her clitty. Now she was getting there.
Dad was trying to talk, but he was just saying nonsense. His brain broken by his little girl’s body. “Princess. Pussy. So good. Such a good little girl. Taking Daddy’s. Oh!”
Not that Sidney was much better. “Oh! Uh….. uh…. Daddy. Yes! Oh Daddy… fffffffFuck. Fuck me.”
Meanwhile Mom directed the action, like either participant was listening. “OK, Danny raise your hips a little more, let’s see you really plow her. Good. Now Sidney lower your knees. Danny get your hands off her tits. Yes, on her ass. Squeeze it. There you go.”
Sidney’s eyes drifted over to her naked brother, standing behind her Mom. The look on his face was odd, and Sidney couldn’t place it. Then she realized, it was straight up desire. He wished that he was fucking his sister, Sidney could tell. Even after all that — him and Mom, her with Dad — Tom still wanted Sidney the most. It made her feel all warm inside.
“Come here, Tommy,” Sidney said. Her brother startled. “Seriously. It’s OK.”
Tom jogged up to his sister. He started to kneel down but she stopped him. Instead, she grabbed her brother’s dick, already doing its best to get hard, and slipped it into her mouth.
“Oh Sidney, yes!” Tom cried out.
“Great idea, honey!” Mom shouted.
“Fuck, yes!” Dad cried, lost in the pleasure of his progeny’s pussy.
Sidney did her best to focus on her brother’s dick. It was salty and sweet, the mixture of her brother and her mom tangy on her tongue. It was different than licking Dad, but no less pleasurable. Sidney pressed her nose into her brother’s pubes. She couldn’t truly suck her sibling off so much as hold his dick in her mouth while her father fucked her. But it was more than good enough for Sidney and her twin.
Then her father drew back, his dick hitting just the right spot, and it ripped Sidney back.
She spit Tom’s dick from her mouth and cried out. Her pussy clamped down, hungrily searching for seed.
“Oh. Oh princess. Daddy’s going to…” Dad slammed his dick as deep as it would go. Time held. The moment stretched out for an eon. The pause between Dad reaching his peak and the moment when his seed spurted straight into his daughter’s unprotected pussy.
For a moment, Sidney thought about all the other options. Her father could cum on her massive breasts. He could splooge all over her shapely ass. She could have swallowed his spend, all that salty, slippery goodness sliding safely down to her stomach.
But in that moment, Sidney realized that none of that would be satisfying enough. She’d have been left wanting more. She needed her father’s cum in her pussy. She wanted it in her womb. Consequences be damned.
A strange, sticky warmth filled Sidney’s pussy. A splashing, singeing essence. The orgasm she’d been so sure was too far away suddenly drove right over her.
Sidney screamed. Her eyes rolled so far back they ached. The orgasm lightninged across her body. To the tips of her nails and the ends of her hair. An all-encompassing experience that split her already cracked consciousness.
She felt something warm splash across her face and realized that Tom was cumming, too. His sperm splattered across her face while her father filled her womb. She was bathing in incestuous sperm. Covered in her family’s fertility.
Her orgasm rolled over her with incredible force. Stretching her nerves out to their limit. She felt her father’s body bucking with every burst. Searing splashes against her cervix. Sidney didn’t so much have an orgasm as she endured it. Hanging on for dear life and hoping that she’d find some semblance of sanity on the other side.
Finally, Dad and daughter both stilled on the couch. Dad pulled out of Sidney with a wet plop. He looked down at his little girl with amazement. Sidney stared up at him. Father and daughter shared the wonderful loving moment together.
The whole family had to recover after that one. The four of them stood there, panting. Looking at each other as if unsure how to untangle themselves.
“I’ll go get us some water,” Tom said, and rushed off to the kitchen.
Sidney stayed limp on the couch. She looked down at her tummy as if she could see inside her womb. She pictured her brother’s and father’s sperm racing, fighting, to inseminate her egg first. Idly, Sidney wondered about which would be the worse genetic result. Either would be disastrous, she thought, wryly. But it was too late to worry about it now.
She got up on unsteady legs and took the glass of water from her brother. The family all shared a dumb, giggly grin as they gulped.
“Well, I think the Christmas cards are going to be something else this year,” Mom said.
“I hope so,” Dad said, “That was a lot of work.”
Mom looked over at her children, “Well, don’t you two have a prom to get to?”
The kids both looked at the clock. It was past 11, the dance had ended hours ago.
“I think we missed it,” Tom said.
“Oh, sweetie,” Mom said, “I’m so sorry. I saw the two of you looking so nice and well… I guess the picture taking got out of hand.”
“It’s OK Mom,” Sidney said, “I’m happy we were able to get some good photos, at least.”
“Yes,” Tom said, “But, if anything, I need to go to bed. I’m wiped.”
“Me too,” Sidney said.
The siblings helped each other, arm-in-arm, up the stairs. Mom and Dad watched them go.
“We’ve raised some good kids, Amanda,” Dad said.
“You know it, Danny,” Mom said.
She bent down and started to put the camera stuff away. Then she headed upstairs to the bedroom, as exhausted as her children. She felt another drip of her son’s sperm run down her legs and she smiled to herself. The day had been so satisfying.
Amanda didn’t bother changing her clothes. She just slipped under the warm comforter. Sleep slid over her, heavy. Then, right as Amanda was about to slip out of consciousness, there was a loud knock at the front door. She startled.
Bang! Bang! Bang!
“Who could it be at this hour?” she asked.
“I haven’t the slightest,” Danny said. He rolled out of bed, now in boxers and a t-shirt, and lumbered downstairs. Amanda sat up on the edge of the bed, listening at the distance.
