The evening began innocently enough, as it often did. The couple met up at the bar and had a few drinks before heading out to dinner. He would have been happy just to spend the evening drinking and laughing with her, but Anna insisted that they go out. She wanted to show off her body, and she wanted to make sure that everyone saw how much fun she was having.

Tim felt a little anxious when they walked into the lobby, and he couldn't help but catch more than one person checking out Anna's revealing outfit. The dress clung tightly to her curvy body, showing off her breasts and hips. It was also tight enough that he could see her panties through the fabric. Her long hair fell down her shoulders, framing her face and giving her an alluring look. Tim knew that he was lucky to have such a beautiful woman as his wife, and he basked in the knowledge that no one else could have her.

"You look amazing," said Tim, kissing her cheek. "I love you."

"Me too," replied Anna, blushing slightly.

They took the elevator up to the restaurant. Leaving the elevator, they passed a group of four young men, one of them turned around and stared at Anna's exposed cleavage. Tim didn't notice, but Anna did. She quickly covered herself with her hands, and smiled shyly at the young man.

The young man winked at her before the doors of the elevator closed, Tim was already walking towards the restaurant. Once inside, they were seated at a table near the window. As they ate their meal, the conversation flowed naturally between them. They talked about everything and nothing, enjoying the company of each other, but a lingering thought in the back of Anna's mind brought her back to a quick look from a stranger.

When they finished eating, they headed outside and walked along the strip until they found a club that played R&B music. The place was crowded, and there was a line forming outside. Tim and Anna joined the queue and waited their turn to enter.

"I haven't heard this song in years!" Anna shouted to Tim as they walked towards the bar. "Come on, dance with me!"

Tim laughed and pulled Anna onto the dance floor. As they moved together to the rhythm of the music, Anna threw her arms around her husband and pressed her body against his. The other couples in the club danced closely, pressing their bodies against each other as though trying to feel as much of the other person as possible. Tim enjoyed dancing with Anna, but he wished that the other dancers weren't so aggressive. He hoped that they wouldn't bump into anyone else.

As they continued to dance, Anna noticed that the crowd was getting bigger, and she pushed closer to Tim. In doing so, she accidentally knocked into a couple who were standing close behind them. As she apologized, she looked up and saw a tall dark-skinned man staring at her. She tried to ignore him, but she couldn't stop looking back over her shoulder. He kept smiling at her and she couldn't help but grin back. His smile made her feel excited and nervous at the same time. Before she knew it, she had moved away from Tim and towards the man. The beat of the music was pulsating as she began dancing with him while Tim watched. She wondered what it would be like to kiss him.

She was lost in the moment and forgot about everything except the man dancing with her. He was warm and muscular, his skin darker than most people she'd ever seen. She felt the heat of his body under her own, and she became aroused by the feeling. His lips looked soft and inviting; she wanted to taste them. She was vaguely aware of the other couples moving around them, including her own husband, but she didn't care. All she could think about was the man holding her and kissing her.

The man put his hand on the small of her back, pulling her even closer to him. Anna gasped when she felt his hard erection pushing into her buttocks. She glanced over her shoulder at her husband and saw Tim watching them intently. He gave her a wink and pointed towards the bar, which made her feel good as she watched him walk to the bar. She turned back to her dance partner, letting the music take control. Suddenly, the man grabbed her from behind, wrapping his strong arms around her waist and lifting her up. She wrapped her legs around his midsection and held on tight, allowing him to spin her around.

He put her back down as she grinned wildly. She could feel the hardness of his penis through his pants pressing against her ass cheeks, and she reached back and grabbed his member, massaging him. She was starting to enjoy the attention she was receiving from this handsome stranger. They both began dancing more aggressively, moving closer together as they grinded their bodies together. The air was thick with sweat and the palpable undercurrent of sex. The music grew louder, and the crowd closed in on them. They were surrounded by other couples grinding their bodies together. It seemed like the whole world was watching them, and she felt flushed with excitement. She felt the need to touch him, to feel his body against hers.

She reached up and ran her hands across his chest, feeling his muscles beneath his shirt. She felt his arms tighten as he pulled her closer to him, pressing her body firmly against his. He nodded towards the exit, looking at Anna to see if she was coming home with him. She tried to signal that she was here with someone, her husband, but the music was too loud. Anna looked around desperately for Tim, hoping that he would come to find her. But she saw him talking to a short woman at the bar, and he couldn't see her attempts to get his attention.

Suddenly, the man squeezed her hand as if to ask her if she was coming. She gave one last fleeting glance towards Tim and followed her dance partner towards the exit. The crowd that surrounded them parted as they exited onto the street.

Once outside, she grabbed her phone and sent a text message to her husband saying that she had left with the man she was dancing with. She wasn't sure where they were going or how far away they were, but that Tim should text her back if he needed her. She turned on the GPS tracking in her phone so that he could keep an eye on her just in case. And then she ran off into the darkness towards her new friend's waiting car.

***

Anna had never been so turned on in her life. She rode through the streets of Las Vegas with the man, who she had learned called himself Marcus, looking out the windows as the bright lights of the casinos flashed by. She couldn't believe how excited she was. Her pussy was wet, and she was incredibly horny. She wished that she could tell Marcus what she really wanted him to do with her, but she didn't want to scare him away. So she kept quiet and let him drive.

After driving for a few minutes, Marcus pulled over to a casino, parking in a deserted spot. He opened the door for Anna and helped her out of the car. The echo of her high heels clicking on the concrete filled the empty parking garage. She felt the warm night air against her skin, and she shivered with the sensation of electricity, the butterflies of anticipation.

Marcus led her into the casino, passing through the automatic doors as they closed behind them. Inside, it was much brighter than outside, almost blinding as light poured from all directions and she was almost taken aback by all the flashing lights and colorful signs. She stood there quietly, unsure of what to do next. But before she knew it, Marcus had grabbed her hand, pulling her forward.

He led her into a private lounge, where several large leather couches were lined up. Each couch had its own table, and each table was covered with bottles of alcohol as well as glasses and ashtrays. The private lounge was still crowded, but a lot more intimate than the nightclub that they had just left. Marcus sat down on one of the couches and pulled Anna close to him. He took her hand and placed it on his thigh, squeezing it gently. He leaned in close to whisper in her ear.

"Is this your first time in Vegas?" he asked.

"Yes," she whispered back.

He smiled at her and pulled her up onto the couch with him. She climbed willingly into his lap and wrapped her arms around his neck. Marcus kissed her passionately, crushing her lips against her own. She moaned softly into his mouth, delighting in the feeling of his strong arms holding her tightly against him. After several moments, Marcus pulled away from her and gazed into her eyes.

"So, I'm guessing that you're married?" he said with a chuckle.

"Yes, but what happens in Vegas stays in Vegas." she replied.

"I guess you're not as innocent as you look," he said. She giggled and playfully punched him in the arm. "What makes you say that?"

"It's written all over your face. You're absolutely gorgeous, and you seem to know what you want. Why don't we take this party upstairs?"

Anna was intrigued by Marcus's proposition, and she smiled nervously. "Okay...but I can't go all the way."

"Of course not. We'll do whatever you want, baby. Just relax and let me show you a good time," he said.

Marcus stood up from the couch and guided Anna to her feet. He grabbed her hand and led her out of the lounge towards the elevators. As they walked towards the elevator, Anna couldn't help but wonder about the meaning behind those words. What did he mean by 'whatever she wanted'? She also wondered if she should be worried about what Tim might be doing while she was with Marcus. She had no idea where they were going, and she feared that Tim may already know that she was gone. As the elevator doors slid open, she felt her phone vibrate. She looked down, a text message from Tim. She quickly read through it, noting that Tim would send a car over to pick her up when she was done. He only asked her to send some pictures over.

They waited for the elevator to reach their floor. Anna felt Marcus's fingers running along her hips as they waited. It felt nice to be touched in such a way by a handsome gentleman. She glanced back at Marcus and smiled, noticing that his cock was growing stiff in his pants. She gave it a quick squeeze, causing him to groan. She felt herself getting wetter and wetter at the thought of what was to come. Once they arrived, Anna stepped out of the elevator and turned to face Marcus. She felt his hands slide up her back and wrap around her, pulling her close as he led her down the hall to his suite.

The room was dark, lit only by a small lamp on the bedside table. Marcus guided Anna into the bathroom, kissing her passionately as they entered. He held her tight against his body as they made out on the threshold, pressing their bodies together. Finally, they broke apart, breathing heavily as they stared into each other's eyes.

"You're beautiful," Marcus said softly.

"Thank you," she replied.

Marcus pushed her backwards onto the king sized bed, pinning her down underneath him. He pulled her dress over her head, exposing her naked breasts to him. He cupped them in his hands, squeezing them gently, then leaning in and sucking one of her nipples into his mouth. She sighed as he ran his tongue around her hard nipple, swirling it around in circles. She felt his other hand slide between her legs and grasp her thighs, spreading them apart. He rubbed his thumb along her wet slit, teasing her before sliding it inside of her.

Anna moaned loudly as she felt his finger slip deep into her. She arched her back, pushing her pelvis into his hand. She felt it sliding in and out of her, rubbing her clit as it went. Her body was on fire, and she was desperate for more. Marcus moved his hand away from her breast and stroked her hair as he continued to finger fuck her. His other hand slid down her stomach and grasped her swollen clit. He rubbed it rapidly as his fingers worked her pussy faster and faster.

"Oh god..." she moaned.

Marcus leaned forward and pressed his lips against hers, kissing her deeply as his fingers pumped in and out of her pussy. Anna moaned wildly, slamming her hips against his hand as she came. Her body began to shake as she fell limp, lying spread eagle underneath him. Marcus leaned over her and kissed her again, licking at her lips until he finally slipped his tongue into her mouth. They kissed passionately as she came down from her high, letting him slowly ease his fingers out of her pussy as she tried to catch her breath.

Marcus pulled his shirt off and tossed it aside, revealing his chiseled chest and muscular arms. Anna admired his physique, admiring the definition in his muscles. He dropped his pants and boxers, revealing his erect penis. It was large and thick, and it was throbbing with anticipation. Anna gasped at its size, amazed at how much harder and bigger it looked than any other penis that she had seen before. She immediately wanted to feel it inside of her.

Marcus crawled onto the bed and positioned himself above her, resting his weight on his elbows as he stared down at her with lust in his eyes. He reached down and grasped his shaft, pulling it towards her mouth. Anna opened wide as he slid it into her, moaning with pleasure as it filled her. He began to thrust into her mouth, sliding in and out of her as she sucked on it hungrily. Anna moved her hands up to Marcus's chest and slid them down his stomach, admiring his muscles as she caressed them. She ran her fingers across his abs, then over his butt, feeling his firm buttocks beneath her fingertips as she sucked his girthy member.

Marcus reached over and turned on the bedside light, illuminating the bedroom. Anna felt a rush of excitement and fear run through her body, knowing that he was taking pictures of her. She didn't care though; she knew that she was an attractive woman and deserved to be pleasured by a man as handsome and as gifted as Marcus. She took his cock out of her mouth and put it next to her face and looked up at Marcus. "Take some good pictures for my husband, he likes to look at them."

He rolled her onto her back, spreading her creamy thighs as he gripped his cock, preparing to enter her. With a single thrust, he sank his entire length inside of her. He fucked her hard, pounding into her body as she laid there, unable to stop him. His balls slapped against her ass as he drove himself into her, fucking her mercilessly. Anna dug her nails into his back, clawing and biting at him as he pounded into her. She screamed out loud as he stuffed her with his fat black dick, making her cum so hard that her whole body shook. He kept thrusting in and out of her, driving his huge tool into her as she begged him to give her more.

"Fuck me...fuck me...please..."

He laughed, feeling her body trembling beneath him as he continued to pound into her. Her skin was bright red, covered in sweat. Her breasts were bouncing up and down as she rode his cock, gasping for air as she climaxed over and over again. Marcus grabbed her ass and squeezed it roughly, forcing himself deeper inside her as he fucked her relentlessly.

"Cum for me, baby...cum for Marcus..." he whispered into her ear.

She cried out loud as he exploded inside of her, filling her up with his hot sperm. Anna collapsed onto the bed, panting heavily as she tried to catch her breath. Marcus removed his cock from her pussy, then moved it up to her mouth. She graciously cleaned his cock off with her mouth, then sucked on it as he lay atop her, holding her tightly against him as they both caught their breath. They laid there for a few minutes, just enjoying the closeness of each other, before Marcus rolled off of her and got dressed.

"How long are you in town?" Marcus asked Anna as he pulled his shirt over his head.

"All week," she replied.

"Think your husband will let you out to play again?" he said, winking.

"I'm not sure. I guess I'll find out tonight after I show him the pictures," she said with a smile.

"Want me to drive you back to your hotel or call a car?" Marcus offered.

"Let's drive," Anna said.

Marcus smiled and picked her up, carrying her over to the door. He opened it for her, then walked out of the room with Anna in his arms. On the ride back to the nightclub they exchanged contact information. Tim had text Anna that he had left the nightclub and went upstairs to their hotel room. Anna sent Tim a message saying that she was getting a ride back with Marcus. Tim asked if she took any pictures and she told him that Marcus took lots of good ones that they could view later.

Marcus and Anna arrived at the hotel Tim and Anna were staying at for the week. Anna leaned over and kissed Marcus in his car, promising that she would see him again before she left town. Anna reflected on the entire evening as she rode up the elevator alone to her waiting husband. The entire time that she was with Marcus, she hadn't given a thought to Tim. She didn't know if Tim would be angry with her for leaving unannounced, but she hoped that he wouldn't be. It was something that they had talked about in the past, Anna had free reign as long as she took pictures of her sexual escapades.

When Anna entered their hotel room, Tim was sitting on the bed, watching television. He looked up at her with a knowing smile on his face. "You're home earlier than I thought you would be," he said.

"Did you miss me?" she asked.

"No," he replied, grinning. Anna punched him playfully in the shoulder. "Liar!"

Tim couldn't wait. "So what happened?"

"I met this guy on the dancefloor and when you were getting drinks he asked me if I wanted to go somewhere with him. We ended up going up to his hotel room after we were at the lounge. He was really nice to me and we had a great time. He made me cum three times before I left."

Tim smiled. "I bet he did. How big was he? Was it like our fantasy?"

"Oh yes. He was so big and thick. I loved every inch of it."

"Wow, sounds like you had fun," Tim said. "Can I see some of the pictures?"

"Of course you can, come here," Anna said, beckoning her husband over to her. She handed him her phone and he started looking through the pictures. He stopped at one and looked at Anna. "Is that him?"

"Yes, that's him. What do you think of him?"

"He looks like he knows what he's doing."

Anna giggled. Marcus knew exactly what he was doing. She had never felt so satisfied sexually. "He's a lot of fun. I'm glad that I got to meet him. Maybe he'll let you watch next time. You know, if you ask nicely."

Anna smirked at Tim as he scrolled through the pictures. "Go ahead, take a look at all of them. I know that you're going to love seeing the rest."

Tim looked at the picture of Anna's legs spread open and Marcus's huge cock buried deep inside of her. It was framed perfectly between her juicy lips. "Holy shit! You look fucking sexy!"

Anna blushed. "Really? I wish that you could have been there with us. I'd love to see how you react to having a huge cock shoved into me. The noises I was making."

"You should invite him over tomorrow night. These pictures are sexy."

"You mean that? You wouldn't mind?"

"No, I wouldn't mind at all, it would be really hot."

"Really?" Anna asked.

"Yeah, I know that you had a good time. I'm cool with it if you want to fuck him again."

"Thanks honey," Anna said, kissing her husband. She smiled at the thought of having a second round with Marcus. She snuggled in close to her husband and began to stroke his hard cock. "I can tell that you like hearing about me getting fucked by a stranger. Does it turn you on knowing that he made me cum three times in a row? How does it make you feel knowing that his cock is way bigger than yours?"

"It makes me jealous," Tim admitted, smiling. "But it turns me on to know you're getting fucked the way that you deserve."

"He was so good, Tim." Anna said, stroking her husband's cock faster. "He fucked me until I came on his dick. It was so big and thick, just like I imagined it would be."

"I'm glad that you liked it," Tim said.

"I loved it. I'm thinking about him right now. How he just filled me up with his huge dick. I can't wait to get him to come over tomorrow night so you can watch."

"Me either."

Anna smiled. She knew that her husband was turned on by the idea of watching her fuck another man. He had fantasized about this for years, but never acted upon it. Vegas had offered them a unique opportunity to live out a fantasy.

"Look at the pictures while I jerk you off. Imagine my lips wrapped around his cock; my tongue licking the underside of his shaft while you watch. I'm getting wet just thinking about it."

Tim smiled as he looked at the pictures. Anna's hand was moving fast as she jerked him off. His cock was dripping precum onto the sheets underneath him.

"Imagine you are standing behind me, watching him penetrate me. Your dick is rock hard, aching to get inside of me as you watch Marcus fuck me like a porn star. You're only allowed to watch though, you're not allowed to touch."

Tim nodded as he continued to watch the pictures. It was hard to believe that Anna's mouth was engulfing a cock that big. He had never imagined that Anna would actually go through with it, he always thought that it was just a fantasy for her. Now it appeared that she was getting the chance to fulfill it.

"What are you going to do when I bring him over? Are you going to masturbate while he fucks me?"

Tim smiled. "Maybe. It would be hard not to play with myself watching you."

"Good. I want you to have as much fun as possible."

Anna used her mouth on him, running her tongue around his tip, savoring his taste. She started to suck him slowly, increasing the pace as she pleasured his cock. Anna moaned as she felt his cock throbbing in her mouth. She sucked him hard, wanting to feel him explode in her mouth. She loved the feeling of his hot jizz filling her mouth, coating her lips and chin. She smiled as she saw the look on Tim's face. He was enjoying the show.

Anna pulled away from her husband's cock, and grabbed a tissue to wipe her lips. She looked up at him, smiling. "Feel better now?"

"Much better. Thanks." Tim smiled back at his wife. "When you invite him over tomorrow, I want to watch."

"Are you sure?" Anna asked. "It's one thing to see a picture, it's another to actually watch it happen. Do you really want to do that?"

"Yes, I want to see you get fucked by a stranger. I've been dreaming about it for years. If you don't want me to watch, we can stop right now."

Anna shook her head. "No, I want you to watch. I want you to see his big cock slamming into me. I want you to jerk off while you watch me get fucked."

"I will," Tim said, nodding. "How could I not?"

Anna curled up next to Tim and he put his arm around her. "Tomorrow night," she whispered. "I can't wait to see your face."

***

They awoke the next morning to the bright sun shining through the window of their suite overlooking the Strip. Vegas by daylight was a wholly different experience. Tim and Anna decided to make the most of their first day in Vegas, they hired a taxi outside of the lobby and headed towards the strip. There was no point in wasting any time; they wanted to begin exploring the city and taking in the sights. Tim spied a sign advertising the Hoover Dam and pointed it out to Anna. He told her that they could visit the dam later in the week. Today was all about gambling and sightseeing.

The driver dropped them off at the Bellagio Hotel and Casino. The Bellagio was well known for its impressive art collection displayed throughout the property. From paintings to sculptures, there was a little bit of everything on display inside the hotel. Anna and Tim enjoyed walking through the various exhibits, admiring the artwork. After seeing enough art, they made their way downstairs to the casino floor. They walked along a long hallway with dozens of slot machines lining the wall. Anna looked through the slots, trying to decide which ones to try. She stopped at one machine and read the name. "Paris. I wonder if this one pays out more," Anna said, pressing the button. The screen lit up and she watched as symbols spun across the screen. She pulled the handle and hit the spin button.

After playing a few rounds of Paris, Anna found herself winning more money than she expected. She cashed out her earnings and stepped away from the machine to look around the casino. "Want to take in a show?" Tim asked. She followed his gaze to a marquee ablaze in light and color. The flashing neon letters spelled out 'SEX SHOW.' Anna nodded at him in agreement.

The theater was lined with a dozen rows of seats facing the stage. The lights dimmed as the crowd settled in. A curtain descended, revealing a giant room full of people sitting and waiting. Two women walked onto the stage. They were wearing sequined dresses that sparkled under the spotlight as they danced. They moved across the stage, mimicking each other's movements. As the audience watched, the two women removed their clothing piece by piece. The audience cheered in appreciation.

Anna sat there in amazement as the two dancers performed on stage. They were so beautiful, she thought. Anna was entranced by the two women as they undressed, watching the way their bodies moved together. They were completely nude now, with their breasts swaying as they danced.

As the music slowed, the two dancers stopped dancing, and a pyramid was rolled onto the stage. The two women walked up to the pyramid and placed their hands on either side of it. The stage lights went dark for a moment, and the audience gasped as the lights came back up. The two dancers were gone. In their place was a large, muscular man who was naked except for a leather loincloth. The stage lights reflected off his bald head. The audience erupted with excitement at the slight of hand. The audience clapped loudly as he climbed atop the pyramid, doing a handstand.

The man started to move, sliding his body up and down the sides of the pyramid. The audience cheered as he reached his hands up and grasped the top of the pyramid. With a loud grunt, he flipped over, landing on his feet. The audience applauded, cheering as the man jumped into the air. He landed, throwing his arms out wide. The crowd went wild.

A woman in a bondage rack was rolled onto the stage by a nude assistant. Her hands were tied behind her back and she was blindfolded. The assistant rolled her to the edge of the pyramid and showed the audience that she was shackled in the rack and unable to escape without assistance. The assistant exited the stage and the bald man walked up to the woman in the bondage rack. He took hold of a chain attached to the rack and pulled it taut. As he did, the woman's body lifted several inches into the air. The audience cheered as the man entered the bondage rack.

The bald man and the woman kissed passionately before the man produced a riding crop. He flicked it against her bare skin, causing her to cry out in pleasure. With each strike, the woman screamed louder and moaned louder. The audience watched in anticipation as the man brought the riding crop down again and again on the woman's exposed breasts. He struck her nipples hard, making them swell and turn red. He moved lower, striking her pussy with the crop.

The woman writhed in pain as the man continued to strike her. The audience watched in rapture as she cried out in pain. Tim glanced over at Anna and saw her eyes were wide and her mouth agape. She looked mesmerized. Tim wondered how anyone could find that arousing. As he watched Anna watch, he wondered if she would enjoy being tortured like that.

Anna noticed Tim was watching her. She turned her head to look at him. He gave her a wink and she smiled back. She turned back to the stage and watched as the man lowered the woman onto a sybian machine. The woman's body arched forward as the vibrating dildo began to pulsate inside of her. The woman's moans echoed throughout the theater as she rode the machine. As she climaxed, the bald man encouraged the audience to cheer her on.

The show ended with a standing ovation for the performers. Anna and Tim made their way out of the theater and into the casino. They were both excited from the arousing and provocative show.

They got a lift back to their hotel and ordered room service. Tim and Anna couldn't keep their hands off of each other as they rode up the elevator to their suite. The door had barely closed behind them as they began tearing off their clothes. Anna and Tim made their way to the couch where she sat on his lap, kissing and grinding against each other. Anna wrapped her legs around her husband and pulled him close, wrapping her arms around his neck. She ran her fingers through his hair as he nibbled at her earlobe.

"I want you right now, Tim." Anna said, pressing her lips against his.

Anna reached down between their bodies and guided Tim's penis toward her wet pussy. She rubbed it up and down her slit, coating it with her juices. Tim slid his shaft up and down her folds, looking into her eyes. They locked lips as he slid inside of her. They made love passionately on the couch of their suite, finishing just in time for room service to be delivered. Anna pulled herself off of Tim and wrapped a robe around herself. She opened the door and let the waiter in. He quickly wheeled the cart over to the dining area and hurriedly left the suite. They ate and napped the afternoon away in each other's arms.

***

Night fell on the Las Vegas Strip as Anna got out of the shower and dried off. She saw that Marcus had sent her a message while she was getting ready for an evening on the town. It read: "I'll meet you in the lobby of your hotel at ten o'clock." She put her robe on and walked into the bedroom to get dressed. Anna responded to Marcus's message: "Want to come up to my room tonight? My husband wants to watch."

Marcus replied: "Fine by me. See you later."

Anna finished getting dressed and walked out into the main area of the suite to show off her outfit to Tim. Anna was wearing a short black dress with spaghetti straps. She wore black thigh highs with a matching garter belt. Her long blonde hair hung down around her shoulders. Tim complimented her appearance, telling her she looked stunning. They kissed and made their way to the restaurant to have a light romantic dinner before Marcus came to visit Anna.

***

When Anna and Tim returned from dinner, they were pleasantly surprised to see Marcus waiting for them in the lobby. Marcus greeted Anna first, giving her a hug. He kissed her on the cheek and Tim shook his hand. Tim introduced himself to Marcus and they made their way to the elevator. When the doors closed, Marcus wrapped his arm around Anna's waist and pulled her close to him. The unspoken switch had been made clear, Anna was Marcus's for the evening. When they arrived in the suite, Anna had asked Tim for a few minutes to get ready. She and Marcus went into the bedroom ahead of Tim, leaving him alone to look out the window over lights of the Strip.

Tim heard Anna call for him quietly from the bedroom. He walked over to the closed door, his heart pounding. He pushed the door open and saw Anna facing him on all fours with Marcus behind her, his cock buried deep inside of her. Anna smiled at Tim as he took a seat in a chair facing the bed. Marcus started to move his hips, thrusting his cock deeper into Anna's tight pussy. Anna moaned softly as she felt him penetrate her fully. His cock felt huge, stretching her insides. Tim looked at Anna as she was impaled on Marcus's cock. He knew she had never been fucked so well. Anna's head was thrown back as she looked at the ceiling, moaning in pleasure. Tim could tell from the look on her face that she was enjoying every minute of it.

Tim watched as Marcus's cock slowly slid out of Anna's pussy and then plunged back in. Anna's mouth opened in a silent scream as she was filled by the man's dick. Tim could hear his wife moan as he watched her body tense up. Marcus began fucking her harder, slamming his cock into her as he pulled her hair. Anna moaned louder as she was taken by another man in front of her husband. Marcus grabbed Anna's shoulders and held her in place as he rammed her pussy.

"Oh God," Anna whimpered.

Tim could hear her beg for more as Marcus's cock slammed into her. He knew that Anna could never get this kind of fuck from him. Marcus's black cock stretched her pussy walls as it plowed its way in and out. Anna's mouth hung open, her tongue lolling out as she succumbed to the more powerful man. Tim knew that Anna had never cum this hard before. Marcus seemed determined to give her the best fuck of her life. Tim had to admit, he was enjoying watching his wife being used like this. He was turned on watching Anna being used by a stranger. Marcus pulled Anna's hair tighter, shoving her face into the pillow as he fucked her.

Anna was moaning louder as Marcus slammed his dick into her faster and faster. Tim watched as Marcus's balls slapped against Anna's ass as he fucked her. The sound of flesh slapping together filled the room as Marcus's cock slid in and out of Anna's pussy. Anna was gasping and groaning loudly as she began to reach her peak.

Tim could tell that she was close. He could see her breathing quicken and her nipples become stiffer. As Anna began to climax, Marcus picked up his pace, ramming his cock into her relentlessly. Tim had never heard the noises that Anna was making before, a high-pitched squeal escaped her lips as Marcus slammed into her. Anna's body tensed up as she came hard, her pussy squeezing Marcus's cock desperately. "Ahhhhhh!" Anna screamed out as she lost control. Her entire body convulsed and her eyes rolled back as she orgasmed. Marcus kept pounding her as she came, prolonging her orgasm as long as possible. Anna finally relaxed, letting her body fall limp against the bed as Marcus held her hips in place.

Marcus withdrew his cock from Anna's pussy, pulling out until just the tip remained inside her and thrust it back inside of her again. Anna was laid out on the bed, her head resting on the pillows, her eyes shut tight. Marcus grabbed her hips, forcing his cock deep into her. Anna moaned and groaned as he continued to pound her. Tim watched as Marcus ravaged his wife endlessly, watching her ass jiggle as he fucked her. Marcus pounded Anna in rapid succession. His balls were slapping against her ass as they bounced up and down with each thrust. Marcus slammed his cock into Anna's pussy, driving her to new heights of ecstasy. After a while he lay on his back and pulled Anna on top of him. She ground her hips into his cowgirl style. Marcus leaned his head back and moaned in pleasure as Anna rode him vigorously. Anna's breasts swayed back and forth as she moved her hips. She looked back over her shoulder at Tim as she rode Marcus.

Anna began to moan louder as she felt herself nearing another orgasm. Marcus held her hips steady and continued to fuck her hard. Anna screamed out as she came for the second time. Tim watched Anna's body shake from the intensity of the orgasm. She leaned forward, biting her lower lip as she came. Marcus kept pumping his cock into Anna as she came. Tim could see her breasts bouncing wildly as she shook on top of him. Anna collapsed onto Marcus's chest, her legs slipping from under her as she came. Marcus let go of her hips as she fell on top of him. They lay there in silence for a few minutes as Anna recovered from her intense orgasm. Marcus looked over at Tim. "Your wife is a lot of fun, man."

Tim nodded. Anna's pussy was still clinging tightly to his cock. He wondered how long Marcus could last. Clearly a lot longer than he could. Marcus reached down and gripped Anna's hips, lifting them off his chest as he resumed fucking her. Anna gasped and groaned as she felt his large cock slide in and out of her pussy. Tim watched with amazement as Anna began to reach another orgasm. Marcus pulled Anna closer to him as he fucked her, holding her body against him. Anna's body shivered and trembled as she came again. Tim could see her dripping down Marcus's shaft as he fucked her robotically. Marcus pulled Anna's head towards him, kissing her passionately as he continued to slam his cock into her pussy. Anna wrapped her arms around Marcus's neck and held on as he fucked her.

Marcus held Anna's hips steady as he fucked her, the wet slap of skin on skin filled the room. Marcus pumped into Anna from underneath, they embraced as Marcus slid rhythmically in and out of her. Tim could tell that Anna was getting close once again. She began to tremble and shake as Marcus rammed his cock into her pussy. Marcus's balls slapped against Anna's ass as they slapped together with each thrust of his cock. Anna moaned and screamed loudly as she came again. "Yes! Yes!" Anna yelled out. Tim watched as her body tensed up and then went limp. Marcus held Anna close and continued to fuck her, prolonging her orgasm. Anna's breasts flopped on Marcus's chest as he fucked her. Anna slowly caught her breath, her mind completely blank. Tim could tell that she was practically catatonic from the intense barrage. Marcus laid Anna on her side, continuing to pump his cock into her pussy as he held her close. She was putty in his hands after having so many orgasms.

Anna moaned as she felt Marcus's cock swelling inside of her; he was going to cum inside of her, right in front of her husband. Anna closed her eyes and let her head loll back against the pillows. Marcus started to growl in frustration as he neared his climax. He pulled her close, holding her head in his arms as he pumped his dick into her pussy. Marcus's body tensed up as he gave one last pump and came deep inside of Anna. She felt his cock pulse inside of her as he unloaded his cum into her. Marcus held Anna tight, keeping her pinned against him as they both caught their breath. They stayed pressed against each other for a while until Tim uttered a single word from the shadows. "Wow!"

Marcus and Anna exchanged glances and smiled.  Anna looked at her husband with glazed eyes and climbed off of Marcus. She walked over to where Tim was sitting and sat in his lap and wrapped her arms over his shoulders. "What did you think honey?" Anna asked.

"It was amazing!" Tim said enthusiastically. "I have never seen anything like that; You're sexy as fuck baby."

Anna blushed slightly and kissed her husband on the cheek. Marcus stood up and thanked Tim before he began to get dressed to leave. Anna went into the bathroom to freshen up, leaving Tim and Marcus alone in the bedroom. Marcus spoke first. "Your wife is amazing," he said. "She is a very lucky woman to have someone so devoted to her."

"Thank you," Tim replied. "I'm lucky to have such an incredible woman. I know she loves me but seeing her with you was...wow."

Marcus smiled warmly. "Hey man, no need to thank me. It was my pleasure. And if you want to do it again before you guys fly out of town, give me a buzz."

Tim laughed. "I don't know that we will be able to fit anything else in before we leave. But thanks."

Marcus stayed silent, but had a bemused look on his face when Anna came out of the bathroom. "I'm going to head out now, I had a good time." Marcus said. "Walk me to the door, Anna?"

She put on her robe and left Tim behind in the bedroom to see Marcus out. Before he left, Marcus turned to Anna. "Give me a call before you leave town, okay?"

"Of course," Anna replied. "Thanks again for everything."

"No problem," Marcus said as Anna pulled him in for a kiss. Anna's robe slipped off her shoulders and Marcus squeezed her ass as they made out. He broke off the kiss and left and Anna closed the door behind him. She went back to join Tim in the bedroom and found him lying in boxers, watching TV.

"Did you enjoy yourself?" Anna asked.

Tim smiled. "Yeah, I did. That was pretty hot, huh?"

Anna blushed. "You mean watching your wife with another man?"

Tim nodded. "Yeah, that was fucking hot."

Anna smiled and hugged her husband. "I enjoyed myself too," she whispered into his ear.

Tim smiled and pulled Anna closer to him. "You really liked that big black dick, didn't you?"

Anna giggled. "Well, yeah. He is huge. I've never seen anyone with a cock that big before. I love how it feels inside of me."

Tim chuckled. "That's what I thought. You like a big cock in your pussy, don't you? In fact, I bet you'd love to have two dicks at once."

Anna smiled seductively. "Maybe someday..."

"You turn me on so much, Anna," Tim said as he stroked her soft skin. "I want you."

Tim kissed her passionately and flipped her onto her back. He pulled his boxers off and easily slid inside of her. Anna moaned softly as he began to move inside of her, slowly at first but picking up speed quickly as he got into it. Tim leaned forward and kissed Anna deeply as his cock drove into her. The excitement of the night's events drove him to the edge within moments, and he exploded inside of Anna's pussy, filling her with his seed.

Afterwards, Tim rolled off of Anna and they snuggled together. Anna rested her head on Tim's chest as they lay in bed. "This is nice, isn't it?" she asked.

Tim nodded. "Yeah, it is."

Anna smiled. "Mmm, I never knew Vegas could be this much fun. We have to come back again next year!"

Tim laughed. "I hope we can afford it."

"Don't worry about that," Anna said. "I'll find a way."

Tim smiled at her. "I like it when you talk dirty to me."
