Maternal Instincts

Lauren smoothed her pink nightgown and ruffled her hair, leaving it hanging loosely down her shoulders. She climbed into bed, waiting for Andy to come to her. It didn’t take long. She heard the doorknob turn and knew that in a moment, her brother would be in the room with her. She laid her head on her pillow and pretended to be asleep.

The door opened slowly. Lauren heard Andy’s footsteps softly pad into the room. 

Andy shut the door behind him. He looked to his sister, apparently asleep, and she yawned, flinging one leg to the side to partly reveal the golden hair under her nightie. Then Lauren buried her face in her pillow to keep from giggling.

The thing was, her mother Caitlin was in the closet. She knelt there behind the partially closed door and watched everything that had happened. It had been a harrowing conversation, hearing that Caitlin knew about their incestuous relationship, but then had come the news that Caitlin wanted to join in. That she knew about how Andy had spied on Lauren and that he had spied on her too. It had led to naughty, dirty, undeniably satisfying sex for Lauren and Andy. Now Caitlin wanted to let go of her shame and live out the same taboo fantasy.

Andy’s back was to the closet now. Lauren’s only regret now was that he was inadvertently blocking Caitlin’s view. He put his hand on Lauren’s hip, ‘awakening’ her.

“Andy?” Lauren mumbled.

“Yeah,” he said, sitting down on the bed beside her.

Lauren looked at him with a superior expression on her face. “I knew you’d come to me. You can’t get enough. You’ve always wanted me.”

“Yes,” Andy agreed, pushing her nightgown up to her waist. “Who wouldn’t want this?”

“I want a kiss,” Lauren said, lifting her face.

Andy did kiss her, and as he did, he lifted her nightie up all the way to her chin. “Let’s get this off,” he said and pulled it over her head.

“Better?” Lauren asked, relaxing against her pillow, watching Andy’s hungry stare fall on her golden tits, plump and heaving with each breath. 

“Much.”

“Yeah, you want these most of all,” Lauren cooed, holding her hands under her breasts. “You can do whatever you want with them—with me—so long as you cover me with cum when you finish.”

“I think I can guarantee that,” Andy smiled.

“Kiss me again. I know you won’t want to after you’ve doused my face in cum.”

“Not for a while,” Andy agreed.

“If only you had someone else to fuck while I washed up,” Lauren teased, glancing at the closet.

“What are you looking at?” Andy asked, turning his head.

“Nothing, bro. C’mon—you said you’d kiss me.”

From the closet, Caitlin watched them embrace, Lauren stroking the back of Andy’s neck as he kissed her. She had to tremble as she watched her daughter put a dainty hand on the growing outline of Andy’s cock.

“I’ve missed you, Andy,” Lauren said.

Andy slid his hands down to her ample hips. “I’ve missed you too. I’ve missed this.”

He kissed her far more passionately this time. Caitlin felt an unaccountable sense of jealousy, both for Andy and for Lauren. She wished it was her being kissed like that. She wished she was able to kiss Lauren with such desire. When Andy finally stepped away from his sister to strip his clothes off, Caitlin’s pussy was twinging. She dropped her hand inside her panties to soothe it.

In less than a minute, Andy was naked. Then he laid on top of Lauren. Caitlin was amazed at how large his cock was and how stiff it had become. She winced on her daughter’s behalf. Apparently Andy didn’t believe in much foreplay. He just mounted the girl and forced his cock inside her. Caitlin would have to teach him better. But at least Lauren was ready to be fucked. She squealed ecstatically when Andy drove himself into her cunt. 

“Your cunt hasn’t gotten any bigger,” Andy said. “It still has to stretch.”

“Christ, Andy, you’re in so deep!” Lauren moaned, hoping her mother was getting a good look at what they were doing.

Lauren took a few more thrusts before she couldn’t think about Caitlin at all. All she could think about was the feel of Andy’s cock inside her eager sex. She loved being fucked by him. She wrapped her arms around him to get more of his prick, pulling him against her chest, lifting her ass off the mattress to wrap her cunt around his erection. Now every time he pumped her back down against the bed, his shaft buzzed against her erect clit. The friction sent her spinning into an orgasm, her inner muscles clamping down on her brother’s prick.

“Take it!” Andy chanted. “Take that cock!”

“I love it, Andy!”

“I knew you would, you little slut!”

“I love being fucked!”

In the closet, Caitlin desperately fingered herself. She panted for breath, her lips wide open as she watched her two children fuck. She imagined it was her being reamed out by Andy. She wondered what it would be like to have his cock ramming into her instead of her own fingers.

Caitlin watched her daughter tighten her legs around Andy’s back, clinging to him with his cock hilted inside her. He wasn’t thrusting into her anymore, he was battering her against the bed with his prick deep in her cunt. Caitlin grew concerned, seeing a pained expression crossing Lauren’s pretty face.

“Andy! Andy!” Lauren gasped. “You’re breaking me in half!”

Andy kept crashing into the bed with her wrapped around him. It was enough to make Caitlin scramble to her feet and throw open the door to the closet.

“Get off of her!” she demanded, running over to the bed. She grabbed Andy’s foot and pulled at it, forcing him to break his endless series of thrusts. He groaned at the interruption.

“Where did you come from?”

“I said get off of her!”

“No!” Lauren keened. “Don’t stop! Mom, please!”

Another strong pull from Caitlin and Andy moved several feet down Lauren’s body, his cock slipping out of her. Exasperated, Andy rolled onto his back. He saw Caitlin staring at him.

“Mom…!”

“Don’t act so abashed,” Caitlin told him. “If you’re fucking your sister, you should be far past the point of embarrassment. Not that I blame you. Lauren is such a slutty whore, how could anyone be surprised she’d fuck her own brother? But if you’re going to fuck my little girl, she should really enjoy it. It should be the best sex ever, not just her letting you stick your prick in and go to town, such a dirty skank that she gets off on whatever you do to her.”

“Mom, oh my God!” Lauren cried. “What does it matter? I was about to come!”

“Oh yeah?” Caitlin demanded. “Why don’t I just let him fuck you in the ass then, since you’ll let him do whatever he wants? I know you’re a slut, Lauren, an absolutely filthy whore, but I still want my son to be a better fuck than that!”

Andy shocked her then, sliding his hand down to tightly grip his giant cock. Suddenly Caitlin couldn’t take her eyes off his erection as he pumped his fist up and down on it, groaning as he masturbated the astonishing length of his manhood.

“Andy, what the fuck are you doing?” Caitlin gasped at him, now torn between anger and an incestuous lust she could barely believe was welling up in her so strongly. “How—how dare you do that in front of me? You stop jerking off that prick this instant!”

“No, Mom, I don’t want to. It feels too good!” Andy was staring openly at her breasts, panting as he watched their heft jiggling under her shirt with each heightened breath she took. “Man, you sure have a nice pair, Mom. I think about them sometime when I’m fucking Lauren. Jerking off is almost as good as fucking her when I’m looking at your tits.”

“Andy!”

Caitlin was shocked by his lack of respect. She had to make him stop. She moved to pull his hand away from his cock, but Andy pulled his own hand back before she could reach it. What she grabbed onto was the full stiffness of Andy’s cock.

Lauren giggled. “Nice and big, isn’t it Mommy? Why don’t you get him off? If he liked jerking off while he looked at you, I bet he’ll like looking at you while you jerk him off even better.”

Caitlin glowered at her daughter. “You are an absolute slut, Lauren. I can see I’ll have to teach you how to really get off. Even if all it takes is a big dick to make you come, you’re a Strucker. You should demand more than a few hard pumps.”

But she was doing it, she was jerking Andy off as he stood hot in her hand. Caitlin didn’t know what came over her. Her pussy was wet, throbbing so heatedly in her panties that she couldn’t think straight. She was angry and frustrated and very, very turned on.

Andy just lay there, grinning as he let his mother jerk him off. Caitlin openly gazed at his huge cock, lips wetly partly as she absorbed just how big it really was, while her hand whipped up and down its length as fast as she could make it.

“Does that feel good, Andy? Is this what you want? Your own mother? Are you really such a sleaze that you’ll not just let your sister fuck you, but you’ll welcome your mother jacking you off?”

“I’m just trying to make you happy, Mom,” Andy said glibly. 

“You want me happy? Here!” Caitlin let go of his cock and leaned over the bed, her ass sticking up in the air. She tugged her jeans down her legs. “Get off your ass, Andy, and fuck me. And you’d better put the work in! I’m not a slut like your sister! You’ll have to try real hard to get me off!”

Andy came up off the bed and slid behind her, pressing his stiff prick against her ass. “Ahh, yeah, Mom, that’s just what I need. A nice piece of ass!”

He grabbed her hips and pulled her back against him. His throbbing cock slid between her buttocks, not penetrating her, but settling in the crack like a hot dog in a bun. He rutted it up and down her ass, getting her skin wet and sticky. 

Caitlin gasped—she could feel his cock growing even more. His throbbing erection ran all the way from the bottom of her ass to the small of her back. No wonder Lauren had come so hard just having that inside her. Even the most frigid woman would get off on being penetrated that hugely. She wouldn’t have any choice.

“That’s it, Mom, give me your fucking ass!” Andy groaned. “Yeah, yeah, I’m going to cream your hole, Mom! You’re going to cart around a load of my cum just like Lauren does.”

As inexperienced and amateurish as he was, roughly dragging his cock between her buttocks, Caitlin felt herself dripping hotly. Her pussy was soaking wet; she’d probably come the moment he entered her. She pushed back against Andy, rubbing her ass against his member like the two of them were grinding on the dance floor.

“Mmmm,” Caitlin moaned, shaking all over from the nearness of his prick, being denied the fulfillment of having it inside her. “Fuck my cunt! Stick it in me and you can come all you want!”

“Yeah, fuck her, Andy, fuck her!” Lauren cheered. “Once you’re inside her, you can do whatever you want. That’s the way it is with sluts.”

Caitlin closed her eyes, forced to admit it was true. She was as big a slut as her daughter. Andy was going to make her come. In a way, it made her feel proud. They felt like a family again, and like any good family, they would share everything.

Andy mounted her, his weight crushing down on her upthrust buttocks. He speared his cock brutally into her lustfully wet sex. Every inch he fed her scraped against her erect clit. As he bottomed out inside her, Caitlin threw her head back and screamed out her orgasm. Andy smirked, withdrew, and thrust back into his mother to give her another one. Caitlin’s eyes rolled back in her head. She really had raised a good son.
