The Sinful Stepmother Ch. 06

Seth stood next to his mom in the kitchen, the sound of the sink running became a background ambience to their conversation. The task of washing that evening's dishes was nothing more than just a distraction to him.

"So, Nick's leaving tomorrow?" He asked as he grabbed a sponge.

His mom nodded, "Yeah, he'll be gone for like two days, I just hope he doesn't do anything stupid at that sleepover."

Seth didn't miss the concern that laced his mom's voice, it was impossible to miss. See, his mom was very protective of him and his brother, he wasn't sure why since they never were really in any type of danger but she guarded them like her life depended on it. It was part of the reason why he never slept over at anyone's house and also the reason he was so surprised when she let his little brother sleep over at one of his friends' houses.

Seth highly doubted his mom was letting it happen just so she could get a good dicking for two days. She may have loved sex but she'd never compromise her children's safety over it. He just couldn't see her doing that.

"You never let me sleep over." He pointed out.

"I know his friend's mom." His mom shrugged, "We went through college together. We were pretty close."

"Didn't you have a boyfriend in college?" He asked.

Seth usually didn't pry into his parents' past relationships, not after what had happened with his real mom. Yet over the past few weeks, he and his stepmom were getting so comfortable that there really wasn't anything left to hide between them. He one hundred percent believed there was a true romantic relationship growing between them.

His mom rolled her eyes, "Yeah, I did. I still don't know what I saw in him."

"What do you mean?" He asked.

She glanced at him, "Honey, I met him when I was just about to graduate college, I was like 21 when that happened. We dated for 5 years, that was 5 years that I'll never get back. I wasted my time with him. I trusted and loved him for 5 years and all I got back for it was finding him balls deep in some cheap broad he paid 50 dollars for."

Seth cringed, he knew his stepmom's relationship with her ex didn't end well but she still sounded bitter.

"Before you say anything, I know what I'm doing with you is wrong." She said, "I never said I was a good woman, I know that what I'm doing technically makes me a slut, but to me, this is better than finding some random guy and fucking him because I was lonely."

Seth was horrified, "But you are a good woman!"

His mom smiled at him, "I'm not. I'm not supposed to love you the way I do, I'm your stepmother, I'm not supposed to be your girlfriend."

"You're not my girlfriend though." He said, setting the dishes in the sink down.

"Then what am I?" She asked him, "Because I'm definitely not acting like your stepmother. Stepmoms don't fuck their stepsons."

Seth had to admit, she had him there. He couldn't say there weren't any feelings between them because there were. He truly loved her, if he had been born only a few years earlier, he would've been trying to become her boyfriend. He was certain she had feelings for him too, he felt it every time they kissed, whether they were fucking or not.

"I don't know," He said, "But I really don't think you're that bad."

She gave him a sad smile, "Thanks, baby. I doubt your father will see it that way."

"He doesn't need to know."

She chuckled, "No, he won't."

Seth knew that their sexual escapades wouldn't come to an end just because his father returned. If anything, their hook-ups would probably become more discrete.

As Seth finished the dishes, he couldn't help but gaze at his mother's beauty. Even in just a simple black tank top, she looked like a goddess. Her beauty was so intoxicating it made him want to kneel at her feet.

Seth leaned in and kissed his mom's neck. She sighed and tilted her head back to allow him more access. Soon, he was pressed up against her body, kissing up and down her neck as she continued to wash the remaining dishes. He moved around her until he was standing behind her, his dick pressed against her shorts-clad ass. She reached behind herself, burying her fingers in his hair.

The kissing shifted from her neck to her lips, the sound of their lips smacking filled the kitchen. The passion of the kiss had Seth ready to burst, he wanted to bend her over and take her but at the same time, he knew that just couldn't happen, hit little brother was still awake and could catch them at any moment.

"I love you." His mom said in between kisses, her mind becoming clouded with passion.

Seth reached up and cupped her breast, groping and squeezing it in his hand. He ran his thumb over her slowly hardening nipple, a sigh escaping his mother's mouth. He slowly and painfully grinded his crotch against her ass, it took every ounce of self-control he had in order to not rail her right then and there.

The sound of someone opening a door upstairs caused Seth to jump back from his mother. He nervously looked around for something to do before his eyes focused on the refrigerator. He walked over to it and opened it, the cool air rushing out and cooling his otherwise heated face.

He looked over as his little brother appeared at the bottom of the steps.

Nick walked into the kitchen, "Hey, mom, can I leave tonight? Ray said his mom was cool with it."

His mom had a red face as she shakily wiped her hands with a towel, "Uh, sure. What time are you leaving?"

"I think eight will be fine." He said, "It's only a ten-minute walk and it won't be too dark."

His mom nodded and took a deep breath, "Okay."

A dark lust took over Seth's eyes, perhaps tonight was the start of their sex marathon.

"Are you going somewhere?" Seth asked as he looked his mom up and down, "Please tell me you aren't going out wearing that."

His mom giggled at him, "No, I'm not going anywhere."

Seth heaved a sigh of relief. His mom was wearing nothing but the lingerie set she bought at that store. The red and black mesh barely concealed her figure. Her garter belt had an opaque red front to it so no one could see in between her thighs but the backside didn't so anyone could get a great look of her ass. Her bra barely held her tits which threatened to spill out of them. The black stockings she wore only made Seth's erection grow even harder.

"Then why are you wearing that?" He asked.

"Well, I figured we'd celebrate having the house to ourselves tonight, right?" She said, giving him a side view of her body.

Seth would've loved to stare at her but his attention was drawn more towards the open curtains around the living room, anyone could look through and see his mom.

His mom followed his gaze and sighed, "Seth, it's like nine o' clock, no one is going to be out walking around and looking through people's windows."

"But Ms. Cawthorne!" He argued.

"Isn't a problem." She finished, "She's probably in her bed sleeping right now, stop freaking out and just let go for tonight."

Seth really wanted to do what she said but his rational side was in control, this was utter insanity. It was one thing to fuck in front of a woman who most likely would never find them again but it was another thing to stand in front of him in front of a window for anyone to see.

His mom let out a frustrated huff, "You know what? Fine, we'll do this your way."

He watched as she stomped over to the windows and shut the curtains. Then she picked her phone up off the coffee table and started opening an app. He couldn't see though since he was still glued to the couch.

The lights in the living room went from yellow to pink, like strip club lights. His mom set her phone down and looked at him with a look that dared him to ask her what she was doing.

"Now, where were we?" She strutted towards him slowly, one leg in front of the other.

Seth backed up on the couch, his mouth slightly agape. He had no idea what she was planning.

His mom stopped in front of him and ran her hands up and down her sides, "Have you ever had a lap dance before?"

Seth swallowed and shook his head.

She smiled, "Then let me show you how one feels."

Seth could only watch as his mom moved so fluidly in front of him, showing off her curves perfectly, it was like she was the living incarnation of a love goddess, either that or she was a deadly succubus ready to drain him of everything he had. Her eyes had that seductive gleam that told him she was one hundred percent on the hunt for a dicking down.

The way his mom moved scared him a little, it looked like she had a little bit too much experience with the way she was moving.

"Your father used to love these." She said as she turned and showed her ass, "I learned how to dance like this for him, too bad he doesn't even pay attention to them anymore."

Seth swallowed as she gently sat on him, her ass brushing against his dick. She rolled her hips and grinded on him, her soft butt massaged him almost perfectly. She looked over her shoulder with a naughty smile before backing her ass up against him.

Now that she was close enough, he couldn't help but notice there was a new scent coming from her. It wasn't bad, if anything, it smelled a lot like candy. He wondered if she had busted out some new perfume or something.

Seth's mom reached over and grabbed his wrist, setting it on her hip, "Touch me, baby. I don't bite."

Seth did as she said and ran his hands up and down her body, feeling the somewhat gritty texture of the lingerie and the smoothness of her skin. His mom moved with his touch, dancing on his lap like she didn't care if anyone saw her.

She bounced her ass on his dick a couple of times, "How does that feel?"

He grabbed her ass cheeks, "That feels nice."

His mom grinned before rolling her hips again. He couldn't believe that his dad used to get lap dances like these, even worse was the fact that he ignored them. Seth loved this lap dance, he would've actually paid his mom if she asked him to.

Seth smirked to himself, he knew his friends would've killed to be in his position. It took everything he had to not rip the lingerie off her body and rail her over the coffee table.

His mom must've sensed his increasing sexual desire because she stood up and took a few steps away. She turned to him, "How about we take this to the bedroom?"

Seth nearly jumped out of the couch. He rushed his mom, yanking her into a kiss. His mom let out a surprised grunt before she responded to the kiss. Her tongue slithered into his mouth, wrapping around his. The sound of their lips smacking was accompanied by lustful moans and groans.

When they broke apart, his mom grinned at him before she reached behind herself and unclasped her bra. She tossed the bra onto the floor before pulling off some of the rest of her lingerie. Seth wasn't far behind, his shirt followed her discarded garments on the floor. She helped him unbuckle his belt before tossing it somewhere behind her.

Seth pulled his mom back in for another kiss. They walked down the hall as they sucked faces, their shadows told a lustful story on the walls as they passed each picture frame. His mom nudged the door open with her foot before grabbing his hand and guiding him in.

Before she climbed into the bed, his mom pulled off her garter belt and threw it off to the side. She pulled her panties down her legs, revealing her juicy dripping pussy to him. She started to pull off her stockings but Seth stopped her.

"Wait, keep those on." He said.

His mom smiled, "Naughty. I like it."

Seth pushed her onto the bed, a grunt escaping her mouth as her back hit the mattress. She raised an eyebrow at him, her eyes questioning his roughness.

He climbed onto the bed and slowly pried her legs apart, his eyes dilating as soon as he saw her pussy. It wasn't long before he climbed in between her legs and started rubbing his tip up and down her slit, her lips slipping open with every rub. He bumped her clit, causing her to bite her lip as she watched him rub himself up and down.

Seth leaned in and pressed his forehead against his mom's, her eyes darting up to meet his. No words were said as they stared into one another's eyes, an intense maelstrom of lust and love swirled in their eyes.

"Get inside me." She said in a low sultry tone, "Now. Fuck me."

Seth said nothing as he pushed into her. Halfway through, he pulled back and shoved himself into her, filling her with his cock. His tip punched her walls, a tingling sensation running up and down her body.

Seth's mom tilted her head back and moaned, "Fuck, baby. That's it."

Seth gripped her thighs and rested her legs on his shoulders. He licked his lips while he eyed her round full tits, this woman was perfect. He didn't care if she was someone else's, tonight she was his. He was going to fuck her and claim every inch of her.

Starting with a rough thrust, he yanked his hips back and roughly slammed into her. He pounded her so hard her thighs slapped against his, her ass clapping against him. His fingernails dug into her stocking-covered thighs.

"Fuck yeah!" She yelled as he continued pounding her, "Give me that dick! I fucking love it!"

One of Seth's hands left her thighs and rested on the back of her head, "You like this, mom?"

"Yes!" She shouted.

"Beg for it." He demanded.

His mom moaned, "Please, Seth, please fuck me. I don't care anymore, just fuck me. I need that dick! I need every inch of that thick fat cock!"

Seth pounded her harder, especially towards the end. His mom moaned with excitement and lust, her cries filling the bedroom. A pillow fell off the side of the bed as they continued to fuck, the smell of sex filling the air.

Finally, Seth felt his orgasm slowly form in his stomach. He leaned down and laid on top of her, his rough abs pressing against her soft stomach. His mom buried her face into his shoulders, her moans becoming higher in pitch.

"Fuck me please!" She screamed into his shoulder, "Please!"

Seth grunted loudly as he pulled back until he was nearly out completely before slamming back into her. A loud smack could be heard with each thrust. His mom's hair jumped, her breasts rolled back and forth. Her screams bounced off the walls.

Seth looked up and started kissing his mom's neck, desperate hungry grunts coming from his mouth like a stranded man in a desert finding water. His noises were primal and harsh.

"I'm about to cum!" His mom groaned, her voice raw from screaming.

"Fucking cum for me!" He yelled.

His mom's eyes widened before she threw her head back and screamed louder than before. She wrapped her arms and legs around him as she screamed her lungs out. Her pussy squeezed him so hard that she threatened to crush him. Her juices squirted all over his tip and coated his veiny length.

In the midst of her orgasm, his mom reached over and yanked off her wedding ring, throwing it off the side of the bed. Seth noticed it and thrusted even harder.

With a sigh, his mom went limp. Her arms and legs fell off of him as he resumed his thrusting. Her mind was clouded and full of sexual passion, she had finally crossed the line from loving stepmother to lover.

Seth's orgasm started to take over, starting at his toes in the form of tingling. It crept up his legs like a ton of tiny spiders before spearing into his balls.

"I'm cumming inside you!" Seth shouted, burying his face in his mom's neck.

"Do it!" She screamed.

The floodgates burst, what felt like a gallon of semen spurted out of Seth. His tip bloated and felt like it was exploding with each pulse. His mother's womb filled with the thick white substance, his sperm painting her walls. Millions of his sperm swam to her core.

"Yes!" They both screamed as they united. A nearby picture frame on the wall fell onto the floor, creating a loud bang.

Seth pulled out just in time as his vision dimmed. He rolled off of her and rested his head on a pillow. He couldn't believe that he'd fucked his mom like that, he had turned her into a complete slut. His mom took a deep breath as she tried to catch her breath.

"I love you so much." She said to him.

"I love you too." He said, leaning in and kissing her.

*

Seth's mom shifted on her hands as her knees dug into the mattress, her black hair was splayed across her back. She wiggled her ass slightly while looking over her shoulder at Seth, who was on his knees behind her.

Seth held her hip with one hand while he guided himself in with the other hand. White gooey liquid dripped out of his mom's pussy, some of it forming trails down her thighs. Her black stockings were discarded on the floor next to the bed, there was no need for the seductive garments anymore.

His mom's eyes shut and her mouth opened to release a loud moan as Seth started to push inside her. Her eyes shot open when he pushed deeper into her faster than she expected.

Seth looked down at his mom's round ass, he loved taking her in doggystyle, the view was always worth it. As much as he loved her tits, her ass was just as amazing. He slid his hips back and forth, his cock churning her insides as he took her.

Her moans were loud yet slow, like his pace. He wasn't fucking her with everything he had, he wanted to warm her up first.

"Come on, mom, open up that pussy for me." He coaxed, "Back that ass up."

Seth's mom did as he said, slowly shuffling back and impaling herself even further on his dick. She let out a groan as his entire length was sheathed inside her. She'd never felt so full before.

"Are you okay?" He asked as he noticed her body tremble.

She nodded, "Yeah, I'm fine. You're just bigger than your father."

Seth felt a silly sense of pride fill his chest. At the same time, he was also cautious, he didn't want to hurt his mom. He'd railed her before and she'd taken his dick like a champ but he also knew that after that brutal fucking she got earlier, she needed to adjust. He moved his hips but kept a slow pace.

"Tell me if you need me to stop." He said.

His mom moaned but didn't tell him to stop.

In a way, Seth liked this slow and leisurely pace. He loved the rough animalistic fucking but he also liked this, it was more romantic than anything. He felt like he could feel everything, the warm wetness of his mom's pussy and her soft and smooth skin pressed against him. Her moans were even different, they weren't full of lust and desperation.

"I love you so much." He said as he watched her ass move back and forth.

"I love you too." She panted.

Five minutes of leisurely fucking later and his mom was starting to adjust. She sat up straighter and her breathing was now steady.

Seth looked up at the mirror on the dresser. When he had bent his mom over on all fours, he had done so to where she was facing a mirror. He could see how debauched her face was, how her tits swung beneath her. He desperately wished he had a camera.

"Are you ready?" He asked.

His mom nodded, looking at him through the mirror.

Seth straightened up his cock inside her before gripping her hips and pulling back. With a grunt, he thrusted into her, roughly stuffing her full of cock. His mom yelled as she got penetrated.

"Mom?" He asked with concern.

"I'm fine." She dismissed, "I'm just still a little sensitive."

She didn't tell him to slow down, so he did it again. After realizing he wasn't hurting her at all, he did it over and over again, eventually forming a rhythm to the fucking. He would drag out inches of his cock at a time before stuffing her full again.

Seth's lust took over again, his rational side handing over control, "Take it, mom."

His mom moaned as she watched herself in the mirror. He ran a hand up her back before reaching beneath her and cupping her breast in his hand. He rubbed her nipples with his thumb, offering her more stimulation.
