The Sinful Stepmother Ch. 05

Seth sighed as he sat back against his seat, the sound of the bus's engine rumbled in the background as the forests outside flew past him.

"Can you tell me something, dude?" Carson asked.

The last thing Seth wanted to do was answer any questions, he was way too tired. His eighteen-year-old brain yearned to graduate already, he had enough of nagging teachers who were part of the reason he was so tired. Then there was the obvious strain of attending the constant weightlifting meetups.

However, the true reason for his tiredness was less innocent. He'd stayed up all night with his mom, fucking and talking. He couldn't believe he had that type of stamina in him, his mom was downright insatiable.

"What?" He asked irritably.

"Is everything alright at home?" Carson asked, "I mean, any time someone mentions your mom or dad, you straight up stop talking. Did something happen?"

"No, nothing happened." Seth dismissed, "I just don't have much to say."

"Well, Ms. Cawthorn told my mom that your dad hasn't been around recently." Carson pointed out, "Seriously, if your parents divorced, you can tell me. I swear I won't try to do anything weird with your mom, I was just joking about that stuff."

Seth nearly growled, Ms. Cawthorn wasn't exactly the most ideal neighbor. She was that one woman who didn't have a husband so she lived through all the other women on the block, one of whom was his mom. That had the obvious effect of making her extremely nosy and gossipy. If word spread that his mom was having sex with someone who wasn't his dad, things could go south very quickly.

"Dude, they didn't divorce." He told Carson, "My dad is just on a business trip, that's all."

"Wait, if he's on a business trip then why did she say your mom was moaning all night?"

Seth's heart nearly jumped out of his mouth. How had he not accounted for someone hearing their groans and moans?

Quick on his feet, Seth said, "Man, she's exaggerating. My mom just hit her hip on the corner of her dresser and she was just hurting, that's all."

Carson shrugged, "I guess that makes sense. I mean, your mom really doesn't seem like the cheating kind."

Seth smiled, if only he knew. His mom said the most debauched things last night, the words she whispered in his ear still rang through his mind. He could still feel the parts of his back from where she ran her nails up and down, basically raking the skin off his back.

The bus came to a stop in front of Seth's neighborhood, signified by a jolt and hiss of the brakes.

As Seth started to sling his backpack over his shoulders, Carson asked, "Are you going to be on Xbox tonight?"

Seth shrugged, "I don't know, I might have chores."

By chores, he meant fucking his mom over the kitchen table or the sink.

Carson groaned, "Alright, man, just text me when you're on."

Seth smiled and walked off the bus. Just as he climbed off the stairs, he spotted his mom's car parked on the curb. At first, he thought it was some other person's car but then he saw his mom sitting in the driver's seat, looking down at her phone.

He walked up to her side and waited as she rolled down the window.

"Mom, what are you doing here?" He asked, "I can walk home."

"I was about to go shopping and I thought you'd want to come with me." She said, "Unless you don't want to, you don't have to."

Seth shrugged, it wasn't like he had anything to do. He didn't have homework, most of his teachers didn't give homework since he was a senior and they could care less.

"Alright, I'll come with." He said before walking around the car. As soon as he opened the car door, he could smell his mom's perfume, an oddly seductive scent. He wasn't sure where she got it but whoever made it knew how to seduce someone.

As soon as he climbed in and shut the door, his mom leaned over and kissed him. A shiver flew up his spine, her kisses still hit just as hard as the first time.

Now that a week or two had passed by Seth noticed his relationship with his mom had changed drastically. It was less mother and son and more like boyfriend and girlfriend. They still acted like family in public but in the bedroom, they fucked like they would never see one another again.

"So, where are we going?" He asked.

"There's a store about an hour drive from here." She said, "I heard they have a pretty good selection there."

Seth raised any eyebrow at her, they rarely ever made long drives like this. He wondered what exactly she wanted to get that would warrant such a long drive but at the same time, he figured it wasn't really any of his business.

As Seth's mom started driving, he couldn't help but mention his conversation with Carson.

"So, Carson was telling me something today, I think you'll want to hear it." He said.

She glanced at him, "What?"

"Well, you know Ms. Cawthorn?"

"That lady two houses down?" She asked, "What about her?"

"Apparently she told his mom that she heard moaning from our house and she knows dad's not home." He said.

His mom sighed, "Fucking gossip. She must've been walking by or something, there's no way she could hear us from her house, our neighbors could barely hear me and your father."

"Do you think she saw us through the window?" He asked with concern.

She shook her head, "I doubt it. We'll just have to be careful."

"Careful how?"

She shrugged, "I guess we can close the curtains. We really don't have to worry about noise, I've screamed in the past and no one's ever said anything. We'll be fine."

"Alright, if you say so."

As Seth followed his mom out of the store, he couldn't help but feel dizzy. When his mom said they were going to a store, he thought they were going to some random department store, not some sex shop in the middle of an outlet.

The store had pink, white, and red lights inside like a seductive nightclub. The smell of perfume inside was intoxicating and not in a good way. To Seth, there was a point where perfume became obnoxious and this store had that.

To make him even more uncomfortable, the store was filled with middle-aged women who kept on looking at him like he was a piece of meat. Even the cashier kept taking glances at him. His mom noticed and made sure to keep him close, not that he'd walk off with any of them since she was still hotter than all of them.

"So, we went here to get lingerie?" He asked her as she handed him the shopping bag.

"Yep." She said, "I needed a new set."

Seth sighed, the entire trip had lasted until evening, the sun wasn't even up anymore. The parking lot lights were on but even then, the car was so far back the lights barely illuminated the car. Luckily, the outlet was pretty empty so he didn't have to worry about anyone trying to rob them.

"Did you see that one woman near the perfume?" His mom asked with a smirk as she shut the trunk.

"No, why?"

His mom shook her head, "She wanted you so bad. If I hadn't been there, I really think she would've tried to make a move."

Seth doubted that, none of the women in his town made a move on him, not even the girls in his high school. To be fair, a lot of the women over 20 in his town were married so it made sense, the women in the shop didn't look married judging from the lack of rings on their fingers.

Seth's mom stopped him from climbing into the car, causing him to give her a confused look.

"Mom?"

She looked around, "I have an idea."

He stood up, "What's up?"

"Well, we're going to be pretty tired when we get home." She said, "What do you think about fucking right here?"

"In the car?" He asked.

She smirked, "Wanna go for it?"

This was new, Seth never had car sex before. His heart beat a tiny bit faster, to say he was excited would be an understatement.

"We'll do it on your side." She said, "There's more room."

Seth nodded and walked over to his side, opening the door and sitting down. His mom looked around again before she walked over and climbed in on his side. She struggled a bit to straddle him but the door being left open helped give her more room. Seth grunted as she shifted on top of him, her hands pressed against his chest.

"This looks so much easier in the movies." She complained as she finally got in a good spot.

"I know right?" Seth chuckled while unbuckling his belt.

His mom bit her lip as she looked down and reached down, unbuttoning his jeans. She unzipped it and started pulling his jeans down, his boxers following suit. Seth couldn't help but feel like she planned this since she was wearing a red summer dress and not anything difficult to get out of like jeans or shorts.

"Let me get my panties off and we'll start." She said, lifting up on her knees slightly to pull her panties down.

Seth watched as she dropped her panties on her seat before she took his dick in her hands. She aimed it at her dripping entrance before slowly lowering herself down. Her eyes fluttered as his tip slowly spread her lips apart.

Seth resisted the urge to groan, the feeling of parting her lips was too good. If he had to describe the feeling, it was like coming into a warm room after being in the cold or climbing under the blankets during a winter night. He could feel the soft flesh of her thighs pressing against his skin, her touch electrifying his skin.

"Shit!" His mom moaned, tilting her head back.

Seth reached around her and hiked her dress up, grabbing handfuls of her ass in his hands. He squeezed and kneaded her rear, enjoying the feeling of her soft ass and smooth skin in his hands. Her apple-shaped ass was one of the hottest things he'd ever seen and touched.

Seth's mom started to move up and down, her pussy sucking and squeezing his cock. She drenched his dick with her juices each time she lowered herself down, engulfing him fully.

"You're so wet." He said, looking up at her in amazement.

She looked down at him with a smile, "I can't help it."

As hot as car sex was, Seth couldn't help but think how inconvenient it was. His mom couldn't rise up fully without banging her head on the car's ceiling. Not to mention, the way he was sitting was really uncomfortable, his back started to hurt.

His mom's knee slipped, causing her to yelp a curse. She collapsed onto his chest, her head roughly hitting his shoulder.

"Ow." She moaned.

"Are you okay?" He asked, his dick still buried inside her.

His mom rubbed her head, "I'm fine. I can't keep this up, let's get out."

Seth's eyes widened before he looked at the stores, there were a few cars in the parking lot though they were all at the front of the parking lot. In the car, their activities were more concealed, someone would have to get close to see what they were doing. Outside though, there was no mistaking it.

"But someone will see us." He said.

"We'll be fine." She assured him, "Plus, it's not like anyone around here will recognize us, we're way too far from town."

Seth wanted to argue but he found himself thinking about what would come about ending things off here. If she didn't suck him off, he'd ride home sexually unsatisfied. She'd cum already, her fluids running down his dick told him that.

"Alright." He said.

His mom wasted no time in climbing off of him and walking towards the hood of her car. She bent over, placing her hands on the side and sticking her ass out. Her front was aimed towards the store so at least there was some concealment, not much but there was some there.

Seth climbed out of the car and walked over behind her. He rubbed his dick up and down her pussy before pushing into her. His mom let out a loud moan as he bottomed out, his hips pressing against her ass. He grimaced, she felt amazing. He couldn't stop himself, he started thrusting as hard as he could.

Seth knew just how risky their position was since the highway was to his back. Anyone driving by would see his mom bent over with him thrusting into her, if a cop saw them, he'd probably arrest them thinking that his mom was just some prostitute.

Yet nothing could stop his thrusts, not even the threat of arrest. Each slap of skin, each squelch from her pussy, each pleasure-filled moan from his mom spurred him onwards. The car shook slightly from the force of his thrusts, the frame threatened to dent as his mom pressed her hands even harder against it. Her moans were loud and arousing, filling the night air.

Seth looked down at her bouncing butt. Her soft round cheeks jiggled with each thrust, each time his hips smacked against the globes of flesh. He couldn't resist, he reached over and slapped her ass, leaving red handprints on her creamy skin. He smacked her ass, leaving his mark on her.

Lust overtook his mind, his eyes grew wide and full of heated lust. His rational side gave way like a weak wall and a lustful, harsh man took over. He wanted to make his mom his, he wanted her to beg for his cock.

"You like this, mom?" He asked, his voice gravelly and rough, "You like getting fucked like a street whore?"

His mom moaned, her pussy clenching around his dick to the point that he was surprised. It was like his words hit her with the force of a bomb. His mom threw her head back and opened her mouth wide in a silent scream. The floodgates burst in the form of loud and uncontrolled moans streaming out of her mouth as she threw her ass back against him.

"Fuck yeah, mom!" He cheered.

"Fuck me!" She said, "Give it to me hard!"

Seth gripped her hips and started thrusting so hard his own hips started to hurt. Sweat ran down his face and body. He watched as his mom's white skin slowly turn pink, her face was already pink. He couldn't help but smile, she must've thought she would fuck him into submission due to her maturity and experience but she didn't account for his stamina and youth, now he was taking her for all she was worth.

Seth looked up and found a middle-aged woman standing at her car, her mouth gaped open and her eyes wide as she stared at them. Her plastic bag was on the ground next to her, a pink box had fallen out, he recognized that box as one of the medium-sized dildos in the store.

He leaned in and licked the shell of his mom's ear, "You see that lady?"

His mom looked on, her eyes lazy and exhausted. She let her body rock back and forth thanks to his rough fucking.

"Y-yes." She moaned.

"Does it feel good getting fucked in front of someone?" He asked her, his hand pressing against her chest and pulling her against him, "I bet you love this."

"Fuck!" She cried out, "I'm about to cum again!"

Seth's eyes never left the woman by her car as he thrusted harder and harder. His mom cried out and moaned as she got taken. Her face grew redder by the second. Her orgasm slammed into her like an eighteen-wheeler, breaking something inside her as she yelled out her pleasure.

"FUCK ME, I'M CUMMING!" She yelled.

Seth knew his mom could be loud, she was loud when she was mad but he'd never heard her so loud while she was getting fucked. Yes, she mentioned screaming at one point earlier but he must've not been home because he would've heard and remembered that.

The squeezing of her pussy was getting to Seth, it was about to do him in. His balls screamed at him to release his load, to dump his load inside her fertile pussy.

"I'm going to cum." He grunted, looking down at her ass.

"Pull out!" She said, "Let me taste it!"

Seth nearly didn't pull out in time. He yanked himself free and watched as his mom sank to her knees in front of him and started stroking him. She opened her mouth and stuck her tongue out, her eyes wild and uncontained.

"Cum for me, cum for mommy." She cooed.

Seth tilted his head back as he started cumming. Hot white thick liquid spewed out of his tip, hitting the back of her throat and coating her tongue. His mom lurched forward and captured his tip in her mouth, his semen filling her mouth. Seth's groans were loud and desperate as his mom sucked him.

His mom swallowed down his load, releasing him with a relieved sigh. She wiped her mouth and smiled up at him, "That was amazing."

Seth's rational side took control, he nearly had a heart attack as the events that had just taken place replayed in his mind. He couldn't believe he'd said what he said to his mom, the same woman who'd kick his ass for calling her such words.

"Really?" He asked, his breathing heavy, "You liked it all?"

"Honey, that was some of the best sex I've had in a long time." She said, getting to her feet, "So much for not fucking in front of anyone though."

Seth looked at where the woman was only to find the woman and her car gone. He smirked, she was probably still thinking about what she'd seen.

His mom limped over to the driver's side of the car, "Come on, let's get home, your brother is probably wondering where we are."
