The material slipped between her tight ass cheeks and Teri turned to the side to see how she looked in the mirror.</p><p>“What do you think?” she asked before turning towards her husband. “Does that look on your face mean you think I look ready for swimsuit season?”</p><p>“Teri, you look stunning,” he said. “I can’t believe how much of a difference your training has made.”</p><p>Teri turned back to the mirror and adjusted the bikini top before stepping back to get a look at herself from head to toe.</p><p>“I was thinking of modeling a few bikinis for Eric. Would that be weird?” she asked.</p><p>Todd felt the now-familiar rush of desire between his legs as his wife expressed a desire to show off her body for her trainer, who also happened to be the man that was fucking her at least twice a week.</p><p>“Weird? No, not at all. Eric would be insane to think it was anything other than hot as hell,” Todd answered.</p><p>She spun towards him and took a few steps closer. “What if you were there too?”</p><p>“Watching?” he asked.</p><p>“No, what if you were sitting on the couch with Eric as I modeled my new bikinis? Would that be weird for you?” she said.</p><p>Todd stood up and pulled his wife into his arms. “Weird? I don’t think so. I guess I feel like it would be really hot. I guess if Eric felt weird then it might be strange for everyone, but otherwise it seems like it would be really sexy to see how he looked at you. I mean, how could he not be turned on? How could he not feel what I’m feeling right now?”</p><p>Teri smiled as she deftly pushed a hand into Todd’s pants and stroked his cock.</p><p>“Are you saying it turns you on to see me in my bikini?” she asked.</p><p>“I’m saying your new bikini body is world class, Teri.” He was already hard and he desperately wanted to fuck his wife. “I’m saying it definitely turns me on to see you in this bikini.”</p><p>“I got a little daring on my shopping trip,” she said. “I figured I’m going to lose this body someday – time is undefeated, after all – so I might as well take advantage and flaunt it while I have it. I’ll bet you’ll really enjoy the show I’m going to put on when Eric gets here.”</p><p>“And what about after the show?” Todd asked as he pushed his fingers into Teri’s bikini bottoms.</p><p>She moaned as he found the wetness between her legs and slipped inside her with ease.</p><p>“Don’t you think Eric should be the one to enjoy my bikini body first?” Teri asked. “After all, he’s the one that built it.”</p><p>Disappointment melded with a deeper kind of desire as Todd feasted on the denial of what he craved most.</p><p>“I guess that’s fair,” he said.</p><p>“Don’t I deserve to share this body with someone that looks like Eric, someone that’s in great shape?” Teri asked as she released his cock and pulled her hand out of Todd’s pants. She reached up, patted him on the stomach, and smiled.</p><p>Todd felt a little bit embarrassed. He wasn’t in bad shape, but he wasn’t in Eric’s league. The man was a personal trainer. His entire business was built around looking exceptionally good with his shirt off.</p><p>“It’s better with him, isn’t it?” Todd asked.</p><p>Teri stepped closer, pressed her body against Todd’s, and said, “Doesn’t fucking me feel better since I got in shape?”</p><p>He nodded as his dick throbbed. She was right. It was hotter to see his wife’s fit, tight body on top of his. It was hotter to feel her body beneath him in missionary. It was all hotter since she’d gotten in shape.</p><p>“Yes,” he answered as his pulse raced.</p><p>“Does it surprise you that fucking Eric feels better than fucking you?” Teri asked as she reached back and untied her bikini top.</p><p>Todd stared at her perky breasts and groaned. His wife was showing him what she wasn’t going to let him have.</p><p>“No, it doesn’t surprise me,” he said as his cock reached a painfully erect state.</p><p>“Does it turn you on, Todd? Is your dick hard because you’re thinking about Eric’s hard body on top of mine?” Teri asked in a soft, seductive voice.</p><p>Todd nodded and his wife reached up to pull his lips to hers for a beautiful kiss.</p><p>“I can’t wait until he gets here,” Teri said. “I’m going to take a quick shower to make sure I’m fresh for him.”</p><p>She walked away and Todd stared at her long, lean body and her beautiful ass as he marveled once again at how good his wife looked.</p><p><br></p><p>“Where’s Teri?” Eric asked as he stepped into the living room and dropped his bag on the floor.</p><p>“She’ll be right out,” Todd said from the couch. “She went bikini shopping today and she’s feeling exceptionally proud of how she looks. She wanted to show you the results of all the hard work she’s put in.”</p><p>Eric couldn’t hide his smile. Of course he couldn’t. Todd had just informed him that his wife wanted to show off her body. He was surprised Eric wasn’t doing a little celebratory dance.</p><p>“I guess that’s a good reason to get our workout started a little later,” Eric said.</p><p>“Have a seat,” Todd said. “She’s going to strut through the living room like it’s her personal runway.”</p><p>Eric strode towards the couch with a confident bounce in his step and dropped onto the cushion at the other end as Todd dealt with decidedly mixed feelings. He was jealous of Eric, but at the same time he was the man responsible for a marked increase in Todd’s sexual pleasure, both from the thrill of watching his wife with another man and from Teri’s increased sex drive as a result of her new body and her reignited lust for the joy of great orgasms.</p><p>Just as Todd was about to try and make small talk Teri appeared in the living room in the white bikini she’d modeled earlier. He glanced at Eric to see the other man’s reaction and saw a hungry smile cross his face. He knew his wife’s trainer was thinking about fucking her. He was staring at her hard, beautiful body and thinking about slipping his cock into her pussy.</p><p>“What do you think?” Teri asked Eric as she struck a pose in front of them.</p><p>“It’s incredible, Teri,” he said. “Your body looks great. It really does, and what a great bikini. I mean, damn, you look amazing.”</p><p>Teri smiled and spun around to show her ass, most of which was on display thanks to the thong. Eric whistled appreciatively, showing very little restraint despite Todd sitting just a few feet from him.</p><p>“What do you think, honey?” Teri asked as she turned to Todd.</p><p>“It’s breathtaking,” he said. “Seriously, everyone is going to stare when you hit the beach this summer.”</p><p>“That’s what I’m hoping for,” Teri said as she bounced excitedly. “Okay, I’ll be right back. I’ve got another bikini to show you.”</p><p>Teri skipped down the hallway and Todd couldn’t help but feel excited at the idea of his wife emerging in another skimpy, sexy bikini.</p><p>“You’ve done amazing things with her,” Todd said. “She’s never looked better and she’s never been more confident. It’s incredible, in so many ways, really.”</p><p>“I agree, but it’s not me,” Eric said. “I can provide a little bit of education, but it’s a client’s willingness to do the work that really makes the difference, and your wife is absolutely willing to put in the work to get what she wants.”</p><p>Todd thought of how Teri worked hard to look good the first time she offered Eric her body. She’d made sure to do everything she could to tempt him into wanting her. She’d put together a plan to seduce him and she’d gotten what she wanted. She was a driven woman.</p><p>She stepped into the room in a shiny silver bikini that was absolutely the sort that would draw every on the beach to her body. Her nipples were clearly showing through the top and when she spun around Todd could barely contain his excitement at how tightly the shiny material hugged her ass.</p><p>“Holy shit,” he said. “That looks amazing.”</p><p>“It really does,” Eric said. “It’s bold. I love it.”</p><p>“I’ve never had the confidence to wear something like this,” she said. “I used to be so nervous about people staring at me on the beach. I hated the idea.” Teri smiled at Eric and stepped a little closer before leaning over. “Not anymore, though. Now I want them to stare. I want people to see what I worked so hard to achieve.”</p><p>Todd looked over and noticed Eric adjust his shorts. He wondered if his wife’s trainer was getting a little bit excited looking at her body in the astoundingly sexy silver bikini.</p><p>“Do you want to see the last one?” Teri asked.</p><p>“I do,” Eric replied.</p><p>She didn’t bother to look at Todd. She turned around and skipped out of the room and down the hall.</p><p>“She really is confident,” Eric said with a smile.</p><p>“Yes she is,” Todd replied.</p><p>Even Teri’s seductive performance earlier in the bedroom was a result of her newfound confidence. She’d lured Todd into a state of deep arousal and then denied him and did so without a care in the world. She did so because she knew she had him wrapped around her finger, and she was right.</p><p>Teri popped her head around the corner and said, “This one’s a lot skimpier and I’m honestly not sure I’d actually wear it to the beach, but I wanted to see what it looked like.”</p><p>“I’m sure it looks good,” Eric said.</p><p>“He’s right,” Todd added. “I’m sure it’s amazing.”</p><p>Teri smiled and stepped into the living room to show what could only be described as a micro bikini. It amounted to little more than small strips of fabric to cover her nipples and vagina with strings to keep them attached to her body. When she spun around her ass was entirely exposed except for the small, thin little strip of fabric that ran down her crack.</p><p>“It looks amazing,” Eric said.</p><p>Todd was a little surprised Teri was being so blatant. She was very nearly naked in front of her trainer and she didn’t seem the slightest bit shy about it.</p><p>“You really think so?” Teri asked.</p><p>“I do,” Eric replied. “You could wear it to the beach, too. No one would think you were crazy for doing so. You’d make some women jealous, but you have the body to pull it off.”</p><p>She smiled at her trainer and spun around to grab her ass and ask, “How does my butt look?”</p><p>“It’s stunning,” Eric said. “You’ve worked hard. You’ve earned the right to show it off.”</p><p>Teri glanced at Todd, flashed a quick smile, and then looked back at her trainer.</p><p>“Are there any exercises that are particularly good for firming up a bikini body?” she asked. “We’re going on vacation in a few weeks and I don’t want to get flabby while we’re there.”</p><p>“Sure,” Eric said.</p><p>“Could you show me?” Teri asked.</p><p>Todd wondered what his wife was doing. This was normally the thing she did when he was out of the room.</p><p>Eric didn’t seem to mind, though. He stood up, moved behind Teri, and put his hands on her hips. “Anything that works your core is a good exercise,” he said while gently twisting her hips. “Even something as simple as an upper body twist is a good way to keep things tight while you’re on vacation. Find a way to add a little weight and it will be even more effective.”</p><p>“What about my butt?” Teri asked. “My new bikinis don’t exactly hide anything back there.”</p><p>“Nor should they,” Eric said. “Your butt looks great.”</p><p>He pulled her a little closer as Teri looked over her shoulder and smiled.</p><p>“Squats are a good option to work your butt,” he said. “The deeper you go, the more they work it.”</p><p>“Will you do them with me?” she asked.</p><p>“Of course,” Eric said.</p><p>They squatted together as Todd watched from the couch. It seemed downright romantic and it was fairly obvious that his wife was indulging in some sort of erotic game. He wasn’t sure if she was sending a signal that he should leave or if she was trying to tease Eric in front of him but he was determined to sit on the couch and watch.</p><p>“That’s good,” Eric said as they rose up after a set of four squats. “Do those every day and it will keep your butt nice and tight. Want to try something else?”</p><p>“Absolutely,” Teri said.</p><p>Eric gestured to the floor. “Get on your back. Let’s do a few butt lifts.”</p><p>Teri smiled and moved to her back as Todd wondered how many times the trainer had told his wife to get on her back and how many times it had led to them fucking.</p><p>“Bend your knees, put your hands flat on the ground, and lift your pelvis towards the sky,” Eric said. “Really tighten your butt when your pelvis reaches the apex.”</p><p>Teri lifted her pelvis towards the sky and Todd couldn’t help but notice that it seemed like she was thrusting her pussy towards her trainer’s cock. He wondered if Eric had suggested the exercise for that very purpose.</p><p>“This feels good,” Teri said.</p><p>“It looks good too,” Eric replied.</p><p>Todd shifted on the couch as his cock came to life at the lewdness of his wife’s exercise in a bikini so small it barely covered her pussy lips.</p><p>“I look good because of you,” Teri said as she sat up and gently pulled on the drawstring of Eric’s shorts. “You gave me the training and the inspiration I needed. It’s only fair that you get to be the first man to enjoy me in this bikini.”</p><p>She pulled his shorts down and freed his cock before wrapping her fingers around it and stroking Eric with a wild look of lust in her eyes.</p><p>“Are you sure?” Eric asked.</p><p>“Don’t worry about him,” Teri said. “He wants to watch you fuck me. He wants to see your cock slide in and out of my pussy. He wants to see me give my body to you. He wants to see you claim what you helped create.”</p><p>Eric stepped out of his shorts, kicked off his shoes, and dropped to his knees. Teri laid back and spread her legs.</p><p>“I’m right, aren’t I Todd? You understand that Eric deserves to fuck me, right? You understand that he deserves my body instead of you, don’t you?” Teri asked.</p><p>Todd was fully erect at that point and it seemed clear that his wife had planned this little dalliance. She wanted him to watch. She wanted Eric to know that her husband was eager to see another man’s cock slide into his wife’s pussy. Todd wasn’t sure if Eric was in on the plan and it didn’t matter.</p><p>“Yes, you’re right,” he said. “I want to watch.”</p><p>Eric pulled Teri’s skimpy bikini bottoms aside and rubbed his fingers over her swollen pussy lips.</p><p>“You’re wet,” he said.</p><p>“I’ve been thinking about you all day,” she replied before moaning at his touch. “I’ve been thinking about your body, about feeling you on top of me, about feeling you inside me. Now take me, Eric. Take my body.”</p><p>Todd shuddered at the intense pleasure that moved through him. To hear his wife offer herself up like that was astonishingly sexy.</p><p>Eric lowered his body onto hers and they kissed as he reached down to guide his cock inside Teri’s wet, waiting pussy. She moaned as he disappeared inside her and Todd moved over to ensure a perfect view. He’d watched on video before, but it was nothing like seeing it in close up. It was nothing like hearing the sounds in close up. It was so much better.</p><p>“Harder,” Teri said. “Pound me. Show him how you fuck me. Show him what I crave.”</p><p>Todd had seen it before, but in person it was so much hotter and so much easier to appreciate that Eric really could fuck her better thanks to his exceptional level of fitness. He’d turned his body into an instrument of pleasure and Teri was on the receiving end of it in a way that clearly pleased her.</p><p>“Holy shit,” Teri cried out. “Make me cum, Eric. Fuck, make me cum. Make me cum!”</p><p>Todd watched his wife’s legs tremble and kick out. He watched her toes curl. He listened to her wild moans. He saw how her pussy lips seemed to pulse around Eric’s cock as he continued his relentless pounding.</p><p>“Fuck!” she screamed. “I’m cumming!”</p><p>She held Eric close as he slowed his thrusts and Todd admired the way her body continued to tremble as he imagined pleasure rushing through her limbs.</p><p>“God, you’re incredible. You’re fucking incredible,” Teri said.</p><p>Eric moved to his knees and pulled out of her pussy as Teri looked at her husband.</p><p>“You understand it even better now, don’t you?” she asked.</p><p>“I do,” Todd replied.</p><p>“Are you hard?”</p><p>“I am,” he answered.</p><p>Teri smiled. “Does that mean it turned you on to watch Eric fuck me?”</p><p>“You know it did,” Todd said.</p><p>“I want you in your bed,” Eric said. “And I want him waiting outside the door. No watching.”</p><p>Todd wanted to protest, but he wasn’t in a position to do so. Teri had been clear that she wanted to give her body to Eric. Besides, he knew he’d get to enjoy her again. Teri wasn’t exactly stingy with the orgasms. She’d fuck Eric in their bed and she might fuck him elsewhere in the house as the day rolled by. Eventually Eric would leave, though, and he could reclaim her. That worked for him.</p><p>“Then let’s go fuck in our bed,” Teri said. “Come on, sweetie. I want you listening by the door. And you can pull on your dick if you want.”</p><p>It was a little humiliating, especially when Eric laughed, but Todd wasn’t going to turn down the chance to watch. It was far too exciting. He got up and followed as his wife and her trainer scampered down the hallway. The bedroom door was shut by the time he reached it. His wife moaned. They were already going at it again. He sat down, pulled out his cock, and started stroking.</p>
