Dirty Mom, Dirty Sis

“Do you wanna see Mommy’s tits, Honey?”

“Yes, Mom. I’d love that.”

“We’re not supposed to do things like this, you know,” Elaine said as she slowly unbuttoned the last remaining buttons on her shirt.

“There’s a lot of things we’re not supposed to do,” her daughter replied. “But that doesn’t always stop us. And it doesn’t stop some people from watching those things. With her hand in her panties.”

Elaine’s heavy tits were now fully exposed and her kids were both gazing at them openly. But she was almost too shocked to notice how exposed she was. She couldn’t believe her kids knew she’d spied on them having sex.

“You knew I was there?” she asked, not knowing what else to say.

“Yes, Mom,” Matt answered.

“Why didn’t you say something? You just … kept going?” Elaine was only taken aback that she’d been found out. It didn’t have any effect on the burning sensation in her pussy. Then Matt pulled his arm from around Dani and reached over to begin exploring his mother’s naked tits. The same boy who’d been giving her a wet pussy simply by being close. Now he was boldly exploring the warm silkiness of her large jugs while his little sister watched and continued rubbing his cock through his briefs. Simply feeling his hand on her tits made her want to scream.

“We wanted you to know about us, Mom.” It was Dani who answered this time. “Matty and I are in love. We’re a couple now and we don’t want to keep it secret from you.”

Elaine moaned slightly as Matt tweezed one of her nipples. “But it’s so wrong,” she claimed.

“That’s true, Mom,” Matt said. “It’s incest and it’s against all the rules. And it was so wrong when you put your hand in your panties and fingered yourself the whole time you watched us. You kept going until you saw me pump my cum inside my beautiful girlfriend.”

“Aww, Matty,” Dani whispered.

Matt then turned his head and kissed his sister’s lips right in front of their mother. It was a deep, loving soul kiss where their tongues played together in a dance of need. But Matt’s hand kept moving back and forth over his mother’s tits, fondling her firm orbs and teasing her nipples with his fingertips.

Elaine was so stunned by her kids’ brazen behavior she could barely speak. But at the same time, she fully understood their love for each other. In those recent weeks, her own love for her son had become sexual. She would’ve felt like a hypocrite to begrudge her daughter the same feelings. Elaine couldn’t tell herself it was okay because she never acted on those feelings like Matt and Dani obviously had because now that her son had his hand on her body his mother only wanted more. But her son and daughter had obviously given this moment some thought so she held back to see what they’d do.

Matt and Dani ended their hot kiss after a long time. There was no mistaking their love in the way they kissed and looked at each other. Like the two of them, she knew it was wrong but she didn’t care.

“Kiss Mom now,” Dani told her brother.

Matt turned to face Elaine. They paused a moment to look at each other. Matt’s hand was still fondling his mother’s tit. Then Dani started pulling down on his briefs. He lifted his ass off the couch long enough to let her pull them down and then off. Dani giggled as she saw her mother’s wide-eyed look, seeing her daughter take her son’s big, naked cock in her hand and start stroking.

The next thing Elaine knew, her son was kissing her deeply, pushing his tongue between her lips. Feeling her son’s tongue swirling in her mouth along with his hand kneading her full, sensitive tits, made the mother’s head spin with excitement. Knowing his sister was just on the other side stroking his cock made her clit throb in a way she’d never felt before.

Elaine felt Matt’s love in his hungry kiss. She knew he was in love with his sister, but she could now see he was in love with her, too. Her son was in love with two women who loved him back just as much. He was in love with the two closest members of his own family.

As they kissed, Matt fondled his mother’s tits a while longer, but his hand soon drifted between her legs. She shifted so she could part her thighs and let him play with her pussy through her panties.

“Those panties are already soaked,” Dani giggled wickedly, obviously watching her brother rub their mother’s pussy through them.

“Mmmm,” Matt moaned into his mother’s mouth.

Elaine couldn’t help wondering if he was moaning more from kissing her or from his sister stroking his cock. She reached for his balls, caressing them while her daughter kept stroking his shaft. Matt finally broke off the kiss just to be able to breathe.

“Fuck, this is amazing,” he said.

“And you’re amazingly hard,” his sister announced.

Elaine watched them in a daze while Matt kept teasing her pussy through her panties. She managed to shrug off her shirt which brought her a bright look of approval from Matt.

“Fuck, I wish I had tits like Mom’s,” Dani pouted.

“Baby, not all big tits are beautiful and not all beautiful tits are big,” he said.

Elaine was impressed with her son and couldn’t help smiling. He turned back to his sister and pulled her top up and off, leaving her half naked with her pert titties jutting out.

“Oh, Sweetheart, you have beautiful tits,” Elaine sighed. “No wonder your brother loves them so much.”

Dani was pleased, but Matt started kissing her again and feeling her cupcakes with both of his hands. She still held his cock, but now her mother’s hand was exploring his shaft and running over Dani’s hand. She moved her hand down to fondle her brother’s balls and give her mother a chance to handle his stiff rod. Matt moaned into his sister’s mouth while the two most important women in his life caressed his cock and balls at the same time.

Elaine’s pulse was racing with excitement. She couldn’t believe she was sitting on her living room couch in nothing but panties with her hand exploring the feel of her son’s cock, or that her hand kept rubbing over her daughter’s while they both felt his beautifully swollen man flesh. Matt soon kissed a trail down his sister’s neck until his lips were on her chest, planting kisses everywhere on her skin. Cupping Dani’s dainty puffs of tit flesh in his hands, Matt proceeded to kiss and suckle each of the girl’s nipples in turn. She moaned heatedly and made eye contact with Elaine.

When mother and daughter locked eyes, a silent understanding passed between them. It was the closest thing to telepathy Elaine had ever experienced. It showed the bond of a mother and daughter, but on top of that it showed the bond of two women in love with the same man. Elaine and Dani had always loved each other as much as any mother and daughter, but there was a intimacy between them now that could never be matched. As mother and daughter, they would never have to be rivals for the man they loved and craved between their legs.

There were now more moans and sighs filling the room from the horny family of three than the movie that was still playing in the background. But with Matt’s erect cock now out in the open, the soft core sleaze on TV began to pale by comparison.

While still paying attention to his sister’s perky tits, Matt pushed a hand between her thick thighs and began rubbing her pussy through her thin shorts. The girl moaned in heat and started humping against her brother’s hand. Elaine could feel the heated throbbing in Matt’s cock.

Dani shifted and raised her ass off the couch so she could pull her shorts off. She wasn’t wearing panties underneath and giggled when she saw the surprised look in her mother’s eye. But then she sat up on the arm of the couch with one foot up against the back and the other on the floor. Her wet, pouting pussy was fully open. Matt paused to pull off his shirt, then he leaned over and started planting kisses over his sister’s thighs and mound. Dani caressed the back of her brother’s head as he gradually zeroed in on the honey-coated slit between her large thighs. The girl moaned deeply as Matt began licking her pussy.

Elaine watched in awe, still stroking her son’s cock as she watched his tongue lap up and down Dani’s slit and alternately dab into her creamy hole. This was a whole world away from spying through a crack in the bedroom door. She wasn’t just watching now. With Matt’s big cock throbbing in her hand she was part of it, part of their love.

Elaine stood up long enough to slide her panties down her legs. She was aware of her daughter gazing at her equally bald pussy, but Dani was even more in a daze with her brother’s tongue lapping and flicking all over her dripping snatch. The mother then knelt down on the carpet right between her son’s legs. She took his cock back in her hand and started licking all around the head of his cock. He made a yummy sound of approval while keeping his lips and tongue in motion over his sister’s slit.

After nothing but the sound of moans and sighs for the past fifteen minutes, Dani broke the silence.

“Fuck, that’s so hot seeing Mom suck that cock,” she said. She sounded breathless while Matt kept licking her pussy even though his mother was taking the end of his pole into her mouth.

“Do it, Mom,” Dani encouraged the busty, older blonde. “Suck Matty’s cock. It tastes so good I know you love it. Show us what a hot, horny mommy you are.”

Now the naughty, dirty-mouthed girl Elaine had spied on through that gap in the door was back. It reminded the mother she had a witness to her first, incestuous exploration of that cock she’d been dreaming of for weeks. She was in this now and felt encouraged to suck her boy’s cock the best she knew how. She rocked her hand and mouth up and down his thick shaft, slurping loudly as her wet lips went back and forth over the ridge of his knob.

Dani was moaning louder than ever as her brother now sucked on her clit while he sank a pair of fingers into her creamy fuck hole. Their mother watched him eat and finger the girl to a shuddering climax while she steadily sucked his rigid bone. Elaine paused in her sucking and just held onto Matt’s cock as she watched her daughter shiver and squeal through her orgasm.
