It was a typical Monday evening, and the gym was packed as usual. Karen was doing her usual workout routine, pedaling away on the stationary bike, when a new guy walked in. She recognized him instantly as her cousin, Tim, whom she hadn't seen in years. He spotted her and gave her a nod, then approached her.

"Hey, cousin. Long time no see."

"Hey, Tim. What brings you here?"

"I'm in town for work, thought I'd get some exercise. This place looked decent."

"Great, well, have a good workout." Karen didn't know how to feel about seeing Tim there. It was a bit awkward since they hadn't spoken in so long and they were both sweating in their workout clothes.

Karen felt a wetness between her legs, which surprised her. She hadn't thought about her cousin in that way before, but now that he was here, all she could think about was his toned body and the way his muscles moved as he exercised.

Tim had caught her eye, too. He noticed the way she looked at him as he worked out, and it drove him crazy. He had always thought Karen was hot, and he felt a twinge in his pants as he imagined having his way with her.

Tim hesitated for a moment, unsure if he should accept the offer. He had always been careful around family, but the thought of getting with Karen in a public place was too tempting to resist.

"Sure, why not?" he replied, taking off his gym shoes and putting them beside the bike. He wiped the sweat from his brow and followed Karen out of the gym.

The two walked towards the bar across the street, eyeing each other all the way there. As they entered, Karen ordered them each a drink and they sat down at a booth in the back of the bar.

"Karen, I've been wanting to say something for a while now," Tim started, his eyes locked onto hers.

"What is it?" she asked back, looking at him with a hint of hesitation.

"I've always thought you were really hot," Tim said bluntly, taking a sip of his drink.

Karen smiled mischievously. "And here I thought you were just being polite. flattered?"

Tim chuckled under his breath before continuing, "Yeah, that too."

They continued to talk and drink for hours, getting more and more intimate as time went on. By the end of the night, both of them were tipsy and things were getting heated between them.

Karen's hands wandered under Tim's shirt as they sat down at the booth. She could feel his muscles rippling under his skin and it made her pulse quicken. Tim leaned in close to her, his breath hot on her ear as he whispered dirty things in her ear.

"You know what I've always wanted? To fuck you hard and make you scream," he growled.

Karen shivered with excitement and leaned in closer to him, pressing her body against his. "You're such a dirty boy," she murmured before biting down on his neck.

Tim groaned in pleasure and grabbed her ass, squeezing it roughly as he ground against her. Karen could feel herself getting wetter by the second as their body heat intensified.

Without another word, they both stood up from the booth and made their way towards the door of the bar. They stumbled out onto the street together, kissing passionately as they walked towards Tim's hotel room.

Once inside, they wasted no time undressing each other and fucking like animals until they were both covered in sweat once again. As they lay entwined in each other's arms, panting heavily, neither one knew how they were going to handle this new level of intimacy between them.

But as far as Karen was concerned, she wasn't going to let anything stand between her and getting what she wanted from this hot cousin of hers.

Tim and Karen lay there, exhausted from their intense session. Tim couldn't believe how lucky he was to have finally gotten with his cousin. But as they lay there, Karen's phone buzzed and she pulled it out to see who was calling.

"Fuck," she muttered under her breath as she looked at the name on the screen. "It's my aunt."

Tim looked up at her curiously. "What's wrong?"

"She's always calling me out about how skinny I am," Karen replied with a sigh.

"Well, tell her to shut the fuck up," Tim said bluntly before lying back down beside her.

Karen rolled her eyes before answering the call. "Hey Aunt Marge, what's up?" she said in a sarcastic tone.

"Oh, nothing much," Aunt Marge replied cheerfully. "I just wanted to know if you wanted to go out to dinner tonight."

"I don't know if that's such a great idea," Karen hesitated, eyeing Tim who was now passed out beside her.

"Oh come on! It'll be fun," Aunt Marge insisted. "Besides, since you're all alone now that Tim's gone." She trailed off suggestively.

Karen blushed deeply but didn't say anything else as she grabbed her clothes and got dressed quickly.

As they sat down at the restaurant, Karen could feel Aunt Marge's eyes raking over every inch of her body.

"So, Tim said you were living here now," Aunt Marge said with a smirk as she sipped on her wine.

Karen rolled her eyes at the mention of Tim. She hated when people brought him up and couldn't help but feel like a joke whenever they did.

"Yeah, we're just here for the summer," Karen replied curtly, not bothering to hide her annoyance.

Aunt Marge leaned forward, her eyes gleaming with mischief. "Well, what are you going to do now that you're not with Tim anymore?" she asked slyly.

Karen hesitated for a moment before answering honestly. "I don't know yet. I'm thinking about going back to school or something."

Aunt Marge chuckled darkly. "Or something," she repeated, emphasizing the innuendo of her words.

Karen felt her cheeks flush as she realized what Aunt Marge was implying. She knew she should be disgusted by her aunt's advances but it was hard to resist the temptation when she was being treated so roughly like this.

"Fuck off," Karen spat out finally, unable to take any more of their dirty talk.

Aunt Marge laughed heartily before turning serious. "Now don't be like that," she cooed before reaching across the table and taking Karen's hand in hers.

"You know I only have eyes for you sweetie," she purred seductively.

The next day was the big event - Tim's sister's wedding. Karen and Aunt Marge arrived first and they were seated at a table together. The two sisters sat across from them, looking anxious and nervous.

As the ceremony began, Karen couldn't help but feel nervous herself. She had never been to a wedding before and even though she wasn't close to her sister or Tim's sister, she wanted to make sure everything went smoothly.

The speeches started and Karen tried hard to pay attention but all she could think about was getting laid again and how much fun it would be to fuck Aunt Marge in front of everyone.

As the reception began, Karen and Aunt Marge made their way towards the dance floor. Tim followed closely behind them, his eyes locked onto their bodies as they moved together in perfect rhythm.

The two sisters were dancing nearby and Karen couldn't resist making eye contact with them when suddenly they were all pulled onto the dance floor together. Tim grinned as he spun Karen around while Aunt Marge leaned into his ear.

"I can't believe we get to dance with these two beauties," Tim grinned, his voice deep and gravelly.

Karen hesitated for a moment before giving into temptation again. She leaned against him closer as they swayed to the music together, feeling his hot breath on her neck.

Aunt Marge smirked over at them mischievously before turning towards Karen again. "You know I'm going to fuck you again tonight, don't you?" she asked slyly.
