The Singing Sibling update

Alan and Lynn Mitchell couldn’t believe what they were seeing. They’d come home only to find their twin daughters melted into each other’s arms. Hands reaching around to squeeze identical asses while bellies rubbed together, pussy meeting pussy.

Beca felt her sex creaming at the feel of Anna’s supple breasts pressed to her own, her wet cunt kissing at Anna’s too.

“Stop this! What’s the meaning of this?” their father demanded.

“You can’t be doing this!” their mother said. “Stop it, stop it!”

Beca shivered when Anna’s hand went down to her groin. Her fingers stroked and scratched the juicy folds of her cunt. Beca trembled, letting out a slow moan as Anna’s palm massaged her. Her sister’s expert fingers soon touched her clit, flicking the stiff bud into jolts of ecstasy Beca could barely stand.

Anna barely pulled her attention away from her twin. “Sorry Mom, Dad, but we love each other. A lot. This is how we show it!”

Alan felt like he’d gone deaf. He couldn’t be hearing this. He wouldn’t allow himself to register it. He saw Lynn shaking her head and did the same himself. “You have to stop this! It’s sick! It’s wrong! She’s your sister, for God’s sake!”

Beca mashed her pussy into Anna’s hand, trying to get more of her sister’s touch on her button. “Can’t stop now!” she cooed up into the air. “I’m about to come!”

“Come for me, Beca! Come!”

Their voices were full of passion. They hadn’t masturbated, fucked, or even seen each other naked for the past seven days. Now, when they came, they came harder than ever.

Beca couldn’t conceive of stopping like their parents wanted them to. This might be a sin, but it felt too good for her to even begin to care. The only thing that mattered to her was the seething wetness between her thighs and Anna’s hands, lips, tongue—anything of hers that might touch Beca there.

She would not give into the temptation to stop this, to try and hide it, to forget all about it and go back to being normal. She’d rather their parents knew the truth for all time than ever stop experiencing this bliss. And Anna felt the same way. So they’d show them, burning their bridges so that the pleasure never had to stop.

Anna didn’t waste a second in cupping Beca’s pussy and really grinding the heel of her hand into it. Beca quivered, Anna’s thumb on her clit, playing it like a virtuoso, adding jagged little joys to the pounding delight of the pressure on her folds. She moaned as her sister circled the little button; her hips rocked, helping Anna to caress her slit as much as it was craving.

Barely able to think, Beca still picked up a remote from the floor beside the couch and used it to turn on the TV. Instantly, their parents were offered another view of their fornicating daughters. This one recorded earlier, the tape showing the manifold other ways in which they enjoyed each other. Scissoring, sixty-nining, strap-on sex. This last used a dildo full of fake cum.

After they had orgasmed and the dildo was removed, Anna grabbed the camera and zoomed in for a close-up on Beca’s pussy, showing she’d given her sister far more cum than mere biology could ever manage. The oversized strap-on she’d worn had been absolutely full of stuff, so much so that once emptied, the excess flowed from Beca’s cunt like honey coming out of an overturned pot.

Seeing the video, and the horror on her parents’ faces at the realization that this was far from the first time they’d been intimate, Beca had a sudden urge to finger someone herself. She moved her hand down to Anna’s pussy, slowing only when she found her pubic hair, and then guiding her fingers through it to her brimming hole.

Anna parted her legs, letting Beca have more room to work, and Beca pushed two fingers inside of her. Her hungry cunt closed on Beca’s fingers: slowly, tantalizingly, Beca began to pump them in and out. Gradually picking up speed, soon fucking Anna’s pussy as fervently as anyone with a cock would do.

She quaked as Anna lowered her head and mouthed Beca’s tit. Anna gripped Beca’s chest, licking and sucking at her swollen nipples. It made Beca feel weak in the knees, especially when Anna opened her mouth wide and took in as much of Beca’s pale breast as she could get her lips around.

Now Anna’s fingers worked at her sex while her mouth attacked Beca’s tits. Beca lost all control. She orgasmed convulsively.

Her whole body quivering, Beca moaned and let go of Anna’s pussy as she had her climax. When it tapered off, she saw her glistening cream all over Anna’s hand.

Anna sucked voraciously at her breasts, kissing and licking the turgid swell of them perhaps even more than she’d touched Beca’s cunt.

Alan took a step forward, loath as he was to come any closer to the obscene sight before them. “We have to stop this, we have to—aah!”

He slapped at the back of his neck, where he’d just felt a sharp prick.

“Ahh!” Lynn gasped, feeling a jab of her own.

Both turned to see Aubrey standing behind them, a syringe in either hand. It was not hard to figure out what she’d done, or what was in the injection they’d been given.

All at once, Anna and Beca’s parents felt like melting snowmen. They fell to their knees, then curled up on the floor, utterly unable to maneuver limbs that now feel loose as lengths of twine.

“Mom, Dad, meet our agent,” Beca said. “Aubrey is going to make sure we get to put on plenty of shows just like this one.”

“And just so we don’t have to worry about stage fright,” Anna added, “we decided to give you the very first watch!”

Beca pulled Anna’s hand back to her womanhood, pleading wordlessly for her sister to finger her again. She clasped Anna’s breasts, caressing and fondling their heaving weight. The feel of her twin’s hard nipples made her shake with lust.

Anna could not settle for that. She pulled her hand away from Beca’s pussy and cupped her own breasts instead, holding them up to Beca’s face. Beca gave in, heart pounding as she took one of Anna’s nipples between her teeth.

Anna gasped when Beca bit into its stiff roundness, sucking at the tip that protruded past her clenched teeth. Beca went to the other, getting a good suckle on its stinging nipple, but just as quickly she was back to the first, torturing it while Anna moaned ecstatically.

“Rub my pussy some more! Make me come again!” Anna said. “Just one more fuck and then we’ll do it with Aubrey. But I can’t wait. I’m too hot. I need to have one good orgasm first!”

Anna closed her eyes and stood legs akimbo while Beca knelt down at her open thighs. She used both hands, opening Anna up and fingering the glossy folds, gloriously painting all of the wet canvas until the pads of her fingers were soaked. Then she went to Anna’s stiff clit, stroking up and down while Anna’s ass quivered and she clenched her teeth.

“I’m nearly there!” Anna hissed. “Just a little more and you’ll finish me off! Yes! Yes! Don’t stop! Oh God, that’s it! I’m coming! FUCK YES!”

Anna’s cunt closed around Beca’s fingers. She wailed out her climax, throwing her head back, spasms rocking her body like they were her sobs working their way through her.

Beca guided a limp Anna to the bed. They both fell to it. Aubrey approached them as Beca waited for her sister to recover. She didn’t know Aubrey was coming up to her until she felt Aubrey’s exploratory touch on the small of her back.

“Let her rest,” Aubrey told her, her tone forceful despite her best efforts to be romantic. “I’ll keep you plenty busy. And if I happen to wear you out, I’ll just fuck Anna next.”

“One second,” Beca said, and quickly hugged Anna, their mouths crushed together, their pussies pressed close.

It was a long moment before they untangled and Aubrey bit her lip, envying them. She knew she’d never be as close to Beca or Anna as they were to each other, but she got to fuck them as much as she wanted, which was the best she could hope for. It wasn’t like she wanted to be either of the twins—except when they embraced like this, so much tighter than anyone had ever held her.

“That’s enough,” Aubrey said. “I have something much better for you to cuddle up to.”

Beca reached down and cupped Anna’s cunt. “Nothing could be better than this.”

“If only we were triplets,” Anna said. “It would make playing together a lot simpler.”

“We’ll do alright,” Aubrey assured her.

She opened up her handbag and drew out her vibrator. Anna and Beca shrieked with laughter.

“Here you are, Anna,” Aubrey smiled. “Something for you to play with while I play with your sister.”
