Dirty Mom, Dirty Sis

The way Dani was on her knees to lovingly service her brother’s cock almost looked like a porn video. Elaine sometimes watched online porn when she needed to masturbate so she’d seen enough examples, but she’d never seen a pair of porn stars look at each other the way her son and daughter were. Their passion for each other went far beyond mere lust. They were a young couple in love, a young brother and sister in love. Elaine’s clit became hotter and harder as she rubbed it and watched.

“Ohhhh, fuck, Dani, be careful, you’re gonna make me cum,” Matt groaned.

Dani pulled off his cock for a brief moment. “Good. Little sister needs a nice big drink of big brother’s liquid love.” Then, just as quickly, she took Matt’s cock back in her mouth and resumed the steady pace of her sucking and stroking.

Dani’s slutty talk was a shock to hear, but it caused her mother to push a finger into her overheated pussy and pump. Elaine finger fucked her slick hole as she watched her son quickly rise toward a climax. When he finally grunted and grabbed his sister’s head, Elaine knew his cock was spurting his load of joy sauce into Dani’s mouth. She quickly pulled her finger back to her clit and frigged the button hard and quick, making herself cum along with her moaning son.

Dani was making muffled yummy noises around her brother’s squirting cock, taking every pulse of his load into her mouth and then down her throat like she’d done it a hundred times before. And there was no doubt about the amount of orgasmic pleasure she was giving her brother. Matt’s head was leaned back as he moaned and gasped, holding the back of his sister’s head while he pumped his pole between her supple lips.

Elaine’s orgasm went on twice as long as her son’s, and when he finally pulled his soaking wet meat from his sister’s mouth they shocked their mother into yet another climax.

“Mmmmm, baby sister loves her brother’s hot, delicious cum,” Dani cooed, looking up at Matt and making a show of licking her lips. There wasn’t a trace of his cum left anywhere. She’d swallowed every morsel. There was a burning light of devoted love in her eyes as she gazed up at her brother. There was also a look of pride in giving him a world class blow job. Or at least another one, as it seemed to their mother.

“God, Dani, that was amazing,” Matt said as he was catching his breath. “I can’t believe how good you can suck my cock. You make me feel like nobody before. Fuck, I’m so lucky to have a girl who can suck dick like you.”

Dani giggled, pleased by her brother’s compliment. Elaine was still recovering from her second orgasm and fighting to keep the door still and not make a sound. But the direction of her kids’ conversation was making that more and more difficult.

“Well, they didn’t call me the blow job queen of Northside High for nothin’,” she boasted.

Elaine was discovering her daughter led a completely different life than the one she’d thought. The supposedly shy girl with low self-esteem had sucked who knew how many cocks before finally sucking off her own brother.

“But that’s all in the past, right baby?” Matt said, guiding his sister up by her hands. “It’s just you and me now and forever.”

“Mmmmm, that’s all I ever wanted,” Dani sighed as she melted into her brother’s arms. “And I know that beautiful dick is all mine, right? Cuz I know you had that thing in as many mouths as I’ve had dicks in my mouth.”

Matt chuckled briefly. “Yeah, but no one makes it feel like you do, baby sis. Besides, this whole being in love thing makes everything feel different. I don’t want to look down and see anyone’s face but yours when I’m getting sucked. It just feels wrong now.”

“Are you sure you don’t mind being with a girl who sucked off really a lot of cocks?”

“That just makes it more special that you chose me,” he told her.

“Oh, Matty, I love you so much.”

“I love you, too, baby.”

They spent a long time kissing and running their hands over each other’s body before Dani asked another question that stunned their eavesdropping mother.

“Matty? Do you miss having Bobby or Ryan suck your cock? I know they both did it for you a bunch of times. And maybe you miss getting to suck them off, too, since I know how good it is to get a nice hard one in your mouth.”

She finished with a quick giggle, but her question was serious. Elaine stopped breathing as she waited to hear what her son was going to say. The fact that he had oral sex with other guys his age, guys she knew as his friends, was the last thing she expected. She was learning as much about her son as her daughter, and the thought of her gorgeous son sucking one of his handsome friend’s cocks was making her pussy broil with sensation.

“I told you I don’t need anyone else,” Matt said. “And I meant it. It was fun with the guys, too, but I’m with my girl now and I’m totally yours.”

“Awww, baby.” Dani nestled her head against her brother’s chest while they fondly squeezed each other’s ass. After a short silence, Dani told him: “I guess it’d be alright if you did something with another guy. I don’t think I’d be jealous of a guy like I would be if it was a girl.”

“Baby, as long as we have each other I don’t care about anything or anyone else.”

Dani was silent another minute or two. Matt’s cock was starting to get hard again and she reached between their bodies to stroke it.

“Or Mom,” she added. “I guess I wouldn’t get jealous if you did something with Mom. It feels like it’s alright cuz she’s family. Is that weird?”

Matt chuckled a little. “Yeah, but no,” he said, “considering you and me, after all. But don’t worry, it’s not like Mom’s about to have sex with her own son.”

“I bet you’d be really surprised.”

“What makes you say something like that?”

“Girls know, silly. They just do.”

Elaine was once again stunned, but her hand was already back inside her panties. Her powers of judgement were completely blurred now. All there was was the driving heat between her thighs.

“Then you know what I’m about to do,” Matt quipped as he guided his sister to the bed.

Giggling louder than she should’ve, Dani lay back on her bed with her full ass perched right at the edge. Matt knelt on the carpet and pushed her legs up and apart while he started licking the girl’s beautifully bald pussy. Her moans and sighs of appreciation came up instantly.

As far as his mother could see through the gap in the doorway, Matt was just as capable of licking a girl’s pussy as his sister was of sucking a boy’s cock. By now, she had heard so much shocking information she gave up trying to process it. She simply slid her finger back into her pussy and watched her son lick and suckle his younger sister’s pussy until the girl moaned and squirmed her way through at least two orgasms.

After that second climax, Matt stood up and held his cock to the girl’s sopping wet pussy. He pushed in the head, then slowly buried the rest of his long shaft into Dani’s hole. She moaned low in her throat as her brother’s rod gradually filled her fresh, young slit.

“Oh, Matty, yesssssss,” she purred. “Fuck me. Fuck your little sister. Fuck your girl.”

Matt steadied himself with his hands on the mattress, holding himself above her with his feet planted on the floor. Then he started to rock his body back and forth, driving his big, piston-like cock into his baby sister’s slippery pleasure hole.

Elaine stared in awe as she watched her son fuck her daughter, a sight she never imagined witnessing. She had a good enough view of his pumping cock to see how his flesh was now glistening with a coat of Dani’s fuck honey. He began pumping harder, faster, making the girl moan louder and deeper. They weren’t even trying to be quiet anymore, and Matt’s forceful thrusting was starting to make sloppy, squelching noises as he shoved in and out of her slippery core.

Their mother did her best to keep quiet and continue to give her clit and fuckhole equal attention. She couldn’t believe how beautiful her own offspring looked as they coupled like destined lovers. The way they moved together was like an erotic dance centered around a brother’s cock and his sister’s pussy. Their mother was overcome by the mixture of love and lust flowing between them. Her pussy began quivering heatedly as she realized the siblings were truly meant to be lovers. It made her sad and joyous at the same time. They could never reveal their amazing love to anyone else, yet they had obviously found their soulmate.

“Fuck me, baby,” Dani hissed breathlessly. “Fuck that fucking cunt with that huge fucking cock! Fuck, fuck fuck!”

Matt groaned and fucked his baby girl even faster. “Oh fuck, Dani, that pussy feels so fucking tight! It feels so good!”

“That’s why I only sucked cock before you, baby. I wanted your baby sister’s cunt hole to be so fresh and tight for you.”

Elaine’s finger was rubbing furiously over her juice-coated pearl.

“Fuck!” Matt growled. “Cum with me, little sister! Cum with me now!”

“Yes! Do it inside me, dear brother. Pump that fucking spunk right up baby sister’s hole!” Dani cried much louder than she meant to. But neither of them even noticed their volume now, and the girl cooed and moaned as her body twisted and turned with an explosion of pleasure. Matt suddenly fell silent but his body tensed and his mother could tell he was giving his sister what she begged him for: a pussy filled with a spray of incestuous cum.

Elaine felt herself cum as hard as her kids. She didn’t know how she got through that powerful an orgasm without making enough noise to give herself away, but when she came down from her peak, Matt and Dani were cuddled up and kissing, oblivious to the rest of the world.

Dazed and breathless, Elaine silently closed the door and tiptoed to her room. She was so hazy in the wake of her orgasms, not to mention the many shocking revelations she’d overhead, that she got into bed and fell asleep within seconds. It was too much for any mother to process. She didn’t know how a night’s rest and the light of the next day would change that, either. For now, total numbness was exactly what she needed.
