On a serene Saturday morning, the sun's rays gently filtered through the beige curtains in Harry and Tamara's modest living room. The room was cozy, with an earthy-toned rug sprawled across the wooden floor, and walls adorned with framed family photos and soft, pastel-colored paintings. The scent of fresh coffee wafted through the air, mingling with the warm, inviting atmosphere.

Harry, a tall man with 33 years old, tan skin, brown hair, and deep brown eyes, sat comfortably on the plush, olive-green couch. He was dressed in red short shorts, revealing his muscular legs, and a simple white tank top that hugged his broad shoulders. His relaxed posture and the soft smile playing on his lips indicated the tranquility of the morning.

Tamara, his beloved wife with 30 years old, entered the living room with a gentle grace. She was small in stature, with ivory skin and long, flowing brown hair that framed her delicate face. Her green eyes sparkled with warmth and affection as she looked at Harry. She was dressed comfortably in a loose, light blue t-shirt that accentuated her C cup breasts and a pair of cozy black sweatpants that hugged her big ass.

"Good morning, love", Tamara greeted Harry with a soft kiss on his cheek before settling down next to him on the couch.

"Good morning, Tam", Harry replied, wrapping an arm around her shoulders. "Did you sleep well?"

"Like a baby," she chuckled, snuggling closer to him.

Just as they were about to enjoy their quiet moment together, the doorbell rang, breaking the peaceful silence. Tamara sighed and reluctantly got up to answer the door.

"I'll get it", she said, making her way to the entrance.

As she opened the door, there stood her younger sister, Lucy. Lucy, at 24 years old, was a striking image of youthful beauty. She shared her sister's small frame and ivory skin tone, but her green eyes held a mischievous glint. Her brown hair cascaded down her back in loose waves. She wore a yellow blouse unbuttoned halfway down, revealing a tantalizing glimpse of her D cup breasts, and a pair of tight blue jeans that accentuated her huge ass.

"Hey, sis!" Lucy greeted with a bright smile, stepping inside.

"Lucy! It's so good to see you", Tamara exclaimed, pulling her sister into a warm hug.

"Hey, Lucy", Harry called from the couch, trying to keep his voice steady. He couldn't help but feel a wave of nervousness wash over him. He had always found Lucy incredibly attractive, and there was a lingering suspicion that she felt the same way about him.

"Hi, Harry", Lucy replied, her eyes locking onto his for a moment longer than necessary. "It's been a while."

Tamara led Lucy into the living room, and she plopped down onto the couch next to Harry, her proximity making his heart race.

"So, what brings you here this early?" Tamara asked, sitting back down and taking Lucy's hand.

"Oh, I just wanted to spend some time with my favorite sister and her wonderful husband*, Lucy said, her smile never wavering. She glanced at Harry, her eyes twinkling with an unspoken promise.

Harry swallowed hard, his mind racing. He couldn't shake the feeling that Lucy's intentions might not be entirely innocent.

"Well, it's always a pleasure to have you here", Tamara said, completely unaware of the tension building between Harry and Lucy.

Harry found it increasingly difficult to focus on anything other than Lucy's presence. He couldn't help but wonder what might happen next, and whether his suspicions about her feelings were true.

"Harry, are you okay?" Tamara asked, noticing his distraction.

"Yeah, I'm fine", he replied, forcing a smile. Just a lot on my mind.

Lucy leaned in closer, her voice a soft whisper. "If you ever need someone to talk to, Harry, I'm here for you."

Harry's heart pounded in his chest as he met her gaze, unsure of what the future might hold.

As the morning wore on, Tamara glanced at the clock and realized it was time to run some errands.

"I need to go buy groceries", she announced, standing up and grabbing her purse. "I'll be back in a couple of hours."

Lucy, trying to keep her excitement in check, nodded with a serene smile. "No problem, Tam. Harry and I will just hang out here."

Harry's heart sank. The thought of being alone with Lucy filled him with nervous anticipation and dread. As Tamara headed towards the door, Harry quickly followed her, catching her arm gently.

"Tam, can I talk to you for a second?" he asked, his voice low.

"Sure, what's up?" Tamara asked, looking at him with curiosity.

He glanced back at Lucy, who was idly flipping through a magazine on the couch, then leaned in closer to his wife. "Please, don't leave me alone with Lucy", he whispered urgently. "I'm really uncomfortable."

Tamara looked puzzled. "Why are you so nervous? Lucy's family. This is a perfect time to get to know her better."

"But, Tam..." Harry started, but Tamara cut him off with a reassuring smile.

"Harry, you're overthinking it. Just relax. Everything will be fine", she said, kissing him softly on the cheek. "I'll be back before you know it."

With that, Tamara left, leaving Harry standing at the door, feeling a sense of impending doom. He took a deep breath and turned back to the living room, where Lucy was waiting.

"So, it's just the two of us now", Lucy said, her eyes locking onto Harry's. She patted the spot next to her on the couch. "Come sit with me."

Harry hesitated for a moment before reluctantly walking over and sitting down beside her. The air seemed thick with unspoken tension, and he could feel the heat radiating from her body.

"So, Harry", Lucy began, her voice soft and teasing. "How have you been?"

"Uh, I've been good", Harry replied, trying to keep his voice steady. "How about you?"

"Oh, you know", Lucy said, leaning in a little closer. "Just living life, staying busy."

Harry nodded, his mind racing. He couldn't shake the feeling that Lucy had ulterior motives, but he didn't know how to address it without causing a scene.

As they sat there, the silence between them grew more palpable, each of them acutely aware of the other's presence. Harry's mind was filled with conflicting thoughts and emotions, unsure of what to do next.

Then, Lucy rested her head on Harry's lap, she let out a soft sigh. "I'm so exhausted from work", she said, her voice low and tired. "I just want to rest my head for a bit, if that's okay with you."

Harry's mind was racing as he tried to control his thoughts and his growing erection. He couldn't believe that his sister-in-law was essentially seducing him while his wife was out running errands. But as he looked down at Lucy's breasts, he couldn't help but notice how perky and full they looked, barely contained by her lacy pink bra.

He could see a hint of her areolas on the edge of the bra, and they were a soft shade of pink that perfectly complemented her ivory skin tone. Harry felt himself getting harder at the thought of touching and tasting them, but he quickly pushed those thoughts away.

"I-I don't think this is a good idea", he stammered, trying to keep his voice steady. "You're my wife's sister and I can't...I can't cheat on her."

Lucy lifted her head slightly, looking up at Harry with a mischievous glint in her eyes. "But what if I want you, Harry?" she purred, her hand trailing down his thigh. "What if I can't resist your big, throbbing cock?"

Harry groaned, his erection now fully evident against his red short shorts. He couldn't deny the intense desire he felt for Lucy, but he also couldn't betray his wife. "Lucy, please", he pleaded, his voice cracking. "We can't do this. It's wrong."

But as Lucy's hand reached for the waistband of his shorts, he couldn't help but imagine her lips wrapped around his cock. "I-I can't", he moaned, torn between his morals and his desires.

Lucy grinned, leaning in closer. "But you want to, don't you?" she whispered, her breath hot against his cock. "You want me to suck your cock, to make you feel good."

Harry's mind was a jumbled mess as he struggled to resist the temptation before him. But as Lucy's lips brushed against his erection, he couldn't hold back any longer. "Yes", he gasped, his hand reaching for her head. "I want you, Lucy. I want you so badly."

Lucy couldn't believe her luck as she pulled down her bra, revealing her pink areolas and nipples to Harry. She watched with delight as his cock began to show through the leg of his shorts, the head already peeking out.

"Mmm, look at you", she cooed, her eyes roaming over his tanned skin and the impressive length of his shaft. "You're so big and hard for me."

Harry groaned as Lucy's hand wrapped around his cock, stroking it slowly and teasingly. He could feel her warm breath on his skin as she leaned in and licked his head, causing him to shudder with pleasure.

"God, Lucy", he moaned, his hips involuntarily thrusting towards her mouth. "You're so good at this."

Lucy grinned, loving the way she could make Harry lose control. She continued to stroke and lick him, her hand moving down to fondle his balls as she took him deeper into her mouth.

Harry's head was spinning as he felt the wet heat of Lucy's mouth on him. He couldn't believe he was doing this with his sister-in-law, but he couldn't deny how good it felt. He was completely at her mercy, and he loved every second of it.

As Lucy continued to pleasure him, Harry couldn't help but think about how far things could go between them. He knew it was wrong, but he couldn't resist the intense desire he felt for Lucy. And as she looked up at him with those hungry eyes, he knew that this was just the beginning.

Lucy couldn't help but admire the sight of Harry's shaved 8 inch cock. It was a beautiful shade of pink, with a tanned skin tone that made her want to run her hands all over it.

She traced her fingers along the length of his shaft, feeling the veins pulsing under her touch. It was thick and hard, and she could feel the heat radiating from it.

As she moved her hand up to his head, she couldn't help but notice how perfectly shaped it was. It was a deep shade of red, almost like a ripe cherry, and it was already glistening with precum.

Lucy couldn't resist the urge to taste him, so she leaned in and licked the head of his cock, savoring the salty flavor. She could feel Harry's hips bucking towards her, urging her to take more of him into her mouth.

But before she could, she couldn't resist playing with his balls. They were a perfect pair, hanging low and full, and she could feel the weight of them in her hand.

Lucy moaned as Harry's hands roamed over her body, his fingers teasing her nipples and his hips thrusting towards her mouth. She could feel the intense pleasure building inside of her, but she needed more.

"Please, Harry," she begged, her voice muffled by his cock. "Fuck my mouth, please."

Harry couldn't resist and he began to thrust harder and faster, his cock sliding in and out of her mouth as he grabbed onto her brown hair.

Lucy moaned and groaned as she was completely at Harry's mercy, taking his cock deep into her throat and sucking him with all of her skill. She could feel the pleasure building in her own body, and she wanted nothing more than to cum for Harry.

As Harry continued to thrust into her mouth, he couldn't help but think about how much he wanted to fuck Lucy in every way possible. He knew it was wrong, but he couldn't resist the intense desire he felt for her.

Harry couldn't believe how good Lucy was at sucking his cock. He couldn't help but ask her, "Aren't you ashamed, Lucy? Sucking your sister's husband's cock with such hunger."

Lucy just moaned and looked up at Harry with lust in her eyes. "I can't help it, Harry. You're just so damn hot and I've always wanted you."

Harry's cock throbbed at her words, and he couldn't fight the intense desire he felt for his sister-in-law. He knew it was wrong, but he couldn't resist any longer.

"Then show me how much you want me," he growled, grabbing onto her hair and thrusting his cock deeper into her mouth.

Lucy moaned and sucked him harder, her own arousal building with each thrust of his hips. She wanted him inside of her, she wanted to feel him stretch her in ways she had only dreamed of.

Lucy was in awe of Harry's massive cock, she had never felt so full and stretched before. She could feel his heart beating through his shaft, and it only turned her on more.

As Harry finally reached his peak, he exploded with a force that surprised even him. His cum shot out in thick ropes, coating Lucy's mouth and tongue with its salty, musky taste.

Lucy eagerly swallowed as much as she could, but some of it still escaped from her lips, dripping down her chin. She couldn't resist kissing Harry, tasting his own cum on his lips.

"That was even better than I imagined", Harry said, his breath ragged and his heart still racing.

Lucy couldn't help but smile, knowing that she had been living in Harry's thoughts. "Well, this is far from over", she said, starting to remove her tight blue jeans and lacy pink panties.

Harry's eyes widened as he saw her bare, wet pussy, ready for him. Lucy's pussy was a beautiful shade of pink, glistening with her arousal. Her lips were swollen and parted, inviting Harry in. Lucy's pubic hairs were trimmed into a perfect airplane landing strip shape, leading the way to her wet and waiting pussy. The dark brown and auburn hairs were neatly groomed, emphasizing the pinkness of her lips.

As she sat on Harry's lap, her yellow blouse was unbuttoned, revealing her creamy skin and her bra pulled down under her large, perky breasts. Harry couldn't help but reach up and cup them in his hands, feeling their weight and softness.

Lucy moaned and arched her back, pressing her breasts even further into Harry's hands. She was desperate for his touch, for his cock inside of her.

But Harry couldn't resist exploring every inch of her exposed body first. His fingers traced along her stomach, down to her hips, and then down to her thighs, where he could feel the heat radiating from her pussy.

Lucy was panting now, her desire evident in her flushed cheeks and dilated pupils. She wanted Harry, and she wanted him now.

Harry couldn't resist any longer, he had to taste Lucy's perfect nipples. As he sucked and licked on them, she moaned and ground her hips against his hard cock.

"You like that, don't you?" Harry growled, his voice dripping with desire.

"Mmm, yes", Lucy moaned, her hands tangled in Harry's hair.

She could feel her orgasm building, and she wanted Harry to be the one to make her come. "I want to cum on your mouth, Harry", she panted, her hips moving faster against his.

Harry's cock was throbbing, desperate for release again. But he wanted to make Lucy cum first. He pulled her down onto the couch, spreading her legs and diving in between them.

Lucy gasped and moaned as Harry's tongue explored every inch of her pussy, his fingers rubbing her clit in just the right way.

"Please, Harry, I need to cum", Lucy begged, her voice filled with desperation.

Harry grinned against her pussy, knowing that he had her right where he wanted her. Say my name again, he demanded, his fingers moving even faster.

"Harry!" Lucy cried out, her orgasm washing over her in waves.

As she came down from her high, she could feel her body shaking and trembling, unable to control the intense pleasure coursing through her. Her pussy was pulsing and throbbing.

But Harry wasn't done with her yet. He continued to lick and suck on her sensitive clit, his tongue delving deeper into her core.

Lucy couldn't help but moan and writhe as he devoured her, her hands gripping the couch cushions as she surrendered to the pleasure.

Harry could feel her getting close again, and he wanted nothing more than to make her cum on his mouth once more. "You dirty bitch," he growled, his voice husky with desire. "You like getting fucked by your brother-in-law?"

Lucy could only nod, her words failing her as Harry's tongue continued to work its magic. She was his to use, his to pleasure, and she loved every second of it.

With one final thrust of his tongue, Harry pushed Lucy over the edge once again, her cries of pleasure filling the room.

As she came down from her high, Harry couldn't resist one final dirty comment. "You're such a dirty slut, cumming all over my face. But I can't wait to do it again."

Harry couldn't resist the taste of Lucy's sweet juices, and he pulled her up to his mouth, making her taste herself. She moaned at the sensation, her hands gripping his hair as she kissed him hungrily.

As they kissed, Harry positioned himself on top of Lucy, his hard cock pressing against her entrance. She could feel the head of his cock teasing her, and she couldn't wait any longer.

"Please, Harry, fuck me," she begged, her voice filled with need.

Harry didn't need any more encouragement. He slowly pushed his cock inside of her, savoring the tightness and warmth of her pussy. Lucy moaned and gasped, her nails digging into Harry's back as he filled her completely.

With each thrust, Harry's big balls slapped against Lucy's big ass, sending waves of pleasure through her body. She couldn't believe how amazing it felt to be fucked by her brother-in-law.

Harry's pace quickened, his thrusts becoming more urgent and desperate. He wanted to make Lucy cum again, to hear her scream his name in ecstasy.

Lucy's moans and cries echoed through the room, driving Harry wild with desire. He could feel his own orgasm building, and he knew that they were both close to the edge.

But he didn't want it to end just yet. He wanted to make Lucy cum one more time before he let himself go.

Harry couldn't hold back any longer. He began to fuck Lucy faster and harder, his cock pounding into her tight pussy with every thrust.

Lucy moaned and cried out, her body writhing beneath Harry as he claimed her. She could feel his cock hitting all the right spots inside of her, sending her into a frenzy of pleasure.

"Oh fuck, Harry", she moaned, her fingers digging into his back. "Don't stop, please don't stop."

Harry could feel himself getting closer and closer to the edge, but he refused to let himself cum just yet. He wanted to make Lucy cum one more time before he let himself go.

With one final thrust, Harry made Lucy explode once more, her cries of pleasure filling the room. He could feel her walls clenching around him, intensifying his own pleasure.

But he wasn't done with her yet. He wanted to make her cum again and again, to hear her scream his name over and over.

Lucy could feel her own cum dripping from her pussy to her asshole, and she couldn't help but feel even more turned on. She knew what Harry wanted, and she was more than willing to give it to him.

As she got down on all fours, her ass in the air and her head resting on the couch, she couldn't help but feel a little nervous. She had never done anything like this before, but the thought of Harry's big cock penetrating her asshole was too much to resist.

"You know what I want", she said, her voice filled with desire. "I know what my sister doesn't give you. I'll give you everything you want, Harry."

And with that, Harry positioned himself behind Lucy, his cock covered in her sticky cum. He slowly pushed inside of her, and Lucy couldn't help but moan at the sensation.

Harry's thrusts were slow and deliberate, driving Lucy wild with pleasure. She could feel his cock stretching her, filling her in ways she never thought possible.

With each thrust, Harry's cock was coated in Lucy's cum, making it even more slippery and pleasurable. Lucy could feel herself getting closer and closer to orgasm, and she knew that Harry was too.

But they weren't done yet. They wanted more, needed more. And they were going to take it. Harry's thrusts were getting faster and harder, the pleasure becoming almost unbearable for both of them. He couldn't believe how tight Lucy's asshole was, and how good it felt to be the first one to fill her.

"You fuck better than your sister", he groaned, his hips meeting hers with each thrust. "So much better."

Lucy couldn't help but smile and moan at Harry's words. She had always wanted him, and now she was finally getting what she desired.

She began to thrust her hips against his, meeting his every move and driving him even deeper inside of her.

"Oh god, I love having my ass stretched by you", she moaned, her body trembling with pleasure. "Tamara just needs someone to show her how to fuck properly."

Lucy couldn't hold back any longer. The pleasure was too intense, and she needed to cum. She started to rub her clit, her fingers moving quickly and expertly over her sensitive flesh.

Harry's balls were slapping against her pussy, adding to the pleasure and driving her even closer to the edge.

"Please, cum inside me", she begged, her voice filled with desire. "I want to feel you fill my virgin asshole with your hot cum."

Harry moaned at her words, feeling himself getting closer and closer to the edge. He couldn't resist her any longer, and with one final thrust, he exploded inside of her.

Lucy could feel his hot cum filling her, and it sent her spiraling into a mind-blowing orgasm. She collapsed onto the couch, her body trembling with pleasure. Lucy hugged and kissed him, her body still trembling from their intense session.

"What did you mean when you said Tamara needs someone to show her how to fuck properly?" Harry asked, his curiosity getting the best of him.

Lucy smiled mischievously. "Well, I have an idea on how to teach her", she said. "But Tamara can never know what happened today. Let's make this a secret between us, Harry."

Harry nodded, understanding the need for secrecy. "What's your plan?" he asked, eager to continue their sinful affair.

Lucy leaned in closer, her lips brushing against his ear. "Tomorrow, just follow my lead", she whispered. "I'll show you how to make Tamara beg for more."

And with that, they both knew tomorrow was going to be even more scandalously erotic. They couldn't wait to push their limits and explore their deepest, darkest desires together.

To be continued...
