Sweat, Lies & Dumbbells

With all the perverted fun they had, the one thing Steve was still missing was Jessica, his gorgeous bisexual half-Asian wife, sneaking around behind his back with someone who also thought they were cheating. It may seem an odd kink but to each their own.

Jessica, at 45, had complained about adding a few pounds, so to support her, Steve contacted the local professional at-home gym company to send a trainer for her. For the first workout, her trainer Chris arrived, a muscular, tan, Asian 30 year old wearing form fitting clothing that showed off his buff physique. His workout shorts did little to hide what Steve suspected was a larger member. They immediately got to work, and Steve left them to work in the basement.

The workouts continued twice weekly as scheduled, with Jessica wearing her same casual workout outfits each time. Over time, she and Chris got more comfortable together. The casual touching of Chris correcting her form expanded into regular touching and light massaging. There was friendly, mutual, subtle flirting between them, and they pretended not to notice it or be affected by it.

Steve had gotten good about disappearing before the workout and given them at least 50-55 minutes before emerging, almost like a trusty alarm clock. Steve would occasionally come up and find Chris pressed over Jessica, stretching her body, and, of course, would make some sort of crude sexual reference. Jessica and Chris laughed, knowing he was kidding, but secretly, she knew Steve would have no problem if she ever pushed the boundaries. In one of his pig moments, he told her that if she ever wanted to do anything with Chris, not to tell him so she would have plenty of sneaky stories of her own. Jessica rolled her eyes and called him a swine. Secretly, part of her was not opposed to the idea, as Chris was extremely hot to her. She had also never done anything behind Steve's back and couldn't imagine doing so.

Over time, Jessica started to lose the weight she had sought, and her body began to look the way they had both been working towards. They celebrated her victories, and Chris's positive affirmations warmed her heart. It didn't go unrecognized by Steve that her workout outfits started to change over time, getting smaller and tighter, and not because of her weight, but because she was choosing to wear skimpier attire around Chris. Steve noticed the regular Amazon delivery of sexy workout outfits, which Jessica attributed to her needing better-fitting clothing.

During the following W/O session, things changed. It was late in their workout, and Jessica was on the floor on her back with one leg in the air, stretching her leg out. Chris spotted her, holding her ankle in his tan hand during the stretch. He began to massage the thigh of her elevated leg with his other hand. She looked at him and smiled. It felt so good, and she was enjoying it perhaps more than she should have. He kept massaging and slowly worked his way down to the rear of her thigh near her ass, also rubbing the front of her inner thigh near her crotch. She didn't stop him or protest and noticeably relaxed into the sensation. He left her leg on his shoulder and continued his massage up her torso. He massaged her stomach, explaining the importance of keeping her core loose. Several times. His hands brushed the bottom of her nearly exposed cleavage. At first, she looked a little tense because this was beyond the workout's scope, but after a minute, she loosened up again. Slowly he expanded his massage to include her tits with one hand and both inner thighs with the other. Absently mindedly, she massaged his muscular brown arm, staring at him lustfully. Just then, the door below opened, and Steve ascended the stairs, disturbing the fun.

They went back into his workout stretching mode as Steve came to the top of the stairs. He commented, "Looks like I arrived just in time before things got out of hand." They both laughed, and as Chris turned to Steve, he blocked Jessica behind him and let an extended finger slide over the cloth between her legs. Jessica shuddered. Chris laughed with Steve and told him that she was doing great and that he would push her to a whole new level in the next session. Steve joked about him working her out into a pile of Jello. "Guaranteed she has trouble walking," Chris laughed on the way out the door.

Jessica looked at Steve and wanted to tell him what had happened. Then she thought about it, and nothing really had happened. Besides, she knew that Steve would be totally up for her doing whatever she wanted. And didn't he tell her not to tell him until much later, even if something did happen? The more she thought about it, the more she thought she may have imagined the whole thing. Chris does turn her on, but he has always been totally professional. Maybe her secret lust had made her think that his usual stretching had been more than that.

The next session began on time, with Steve closing the door downstairs for at least 50 minutes. She was dressed in a thin thong, a tight pair of shorts, and a shirt so transparent it was easy to see the outline of her breasts in her sports bra. Chris said this workout would be a hard one, so they should start by stretching her. Just like the end of the last session, she lay on her back, and he began contorting her body. One thing she noticed that was different was he stared into her face the whole time. Again, he began the massage of her shoulders and thighs. Jessica knew where this was heading but said nothing, likely torn between keeping the workout to business and her building desires. Chris began to work his hands underneath her bra and massage her tits. At the same time, he released her leg and used that hand to rub the line just about her tight shorts, brushing his fingers under the waistband. The look on her face was a combination of confusion, excitement, and lust, her mind likely racing with what she should do next. Chris then pulled her shirt and sports bra up, exposing her nipples, which were erect from all the attention. He then leaned over and began to kiss her chest, taking a nipple in his mouth. Chris sucked on one nipple, then the other, licking and kissing her breasts, causing her to squirm a little. At the same time, his other hand had begun rubbing Jessica's pussy through the thin fabric of her shorts. He leaned over and whispered in her ear, "Don't worry, we won't count this session, so you don't lose any training time."

Jessica tilted back a little as Chris slid his hand into her shorts and was now rubbing her folds and clit with his fingers. Jessica began to slowly rock her hips to his motions as he worked her. At one point, she looked up, momentarily alarmed, remembering Steve was in the house. She looked at the clock and realized they had at least 45 safe minutes and an alarm if otherwise, so she relaxed into the moment. Chris again continued suckling on her tits. Her eyes narrowed, and she bit her lower lip as her face took on a lustful look. She simply decided to just let it happen.

Chris kept working her body, and her breathing got rapid and shallow as she began to moan softly. As she was swept away, she reached out and grabbed Chris's cock, which had grown hard and was now breaking free of the waistband of his shorts.

Jessica began to rub the tip of his cock with her hand, then worked her way down the long, smooth dark shaft. Chris's cock was massive, maybe 8 or 9 inches in length and about 3 inches in diameter, and she was barely able to wrap her fingers completely around it. After she stroked Chris for a few minutes, he sat back and slid his shorts off, leaving just his small tank top that made him look more ripped and his muscles bigger still. His cock, now ten inches fully erect, and he leaned it over towards Jessica's mouth. She opened wide and, taking the tip of his dick, licked around the head, working it into her mouth. Chris moaned a little as she tried hard to work her soft lips over the length of his big cock, but she was unable to get the whole thing in. She compensated by running her hands down his shaft with her lips. Each time she pulled him in, she worked on her gag reflex until she finally felt his balls against her chin and her throat expand to accommodate his monstrous tool. Never having experienced a woman who could swallow his full girth, he closed his eyes, lost in the moment fucking her throat.

Finally, he returned to himself, removed it from her mouth, and moved around to her feet. He grabbed the waistband of her shorts and thong and peeled them off her body together. She now lay in front of her trainer, fully exposed. Her pussy was glistening pink and swollen as her cunt begged for him. Chris grabbed one leg in each hand and spread her fully open. He then lowered his mouth to her sex and ran his big tongue up and down her folds and over her smoothly shaved mound. Jessica wiggled and squirmed wildly as Chris went to work on her, dipping his tongue in and out of her. Her body started to quiver, then convulse as she arched her back in orgasm, and her face contorted. She began to cry out, then caught herself remembering where she was and that Steve might hear her. Her body finally went limp as her orgasm washed over her. Watching her cum seemed to heighten Chris' desire more. He sat up and took his swollen brown cock, and rubbed it up and down the length of her slit, covering himself with her juices.

Still sensitive from her orgasm, Jessica jerked uncontrollably as he rubbed his cock against her pussy. Chris swirled the head of his dick against Jessica's cunt and began to push forward, giving her time to adjust slowly. Her pussy and glistening pink lips stretched for Chris's considerable size. With a few thrusts, he was entirely in. Jessica moaned with pleasure as he began to fuck her. She wrapped her legs around him, digging her heels against his ass and grinding her pussy on him. Jessica's second orgasm took her as Chris increased the tempo to push her further over the edge, driving into her hard. Chris's motions became irregular, and it was apparent he, too, was going to cum. He moved to pull his cock out, unsure of her preference, but she pulled him to her again. He pounded her even harder; she could feel him grow larger, and then he shot his load deep inside. They were both in bliss, kissed and moved together slowly as his cock began to relax and retreat.

They both lay there for a minute motionless, catching their breath, and then he gently wiped her off with his workout towel. He told her she was amazing.

Just then, the downstairs door opened.

They dressed quickly, hearing the footsteps on the bottom of the stairs. They returned to their usual stretching positions with just a moment to spare.

Steve came into the room and made one of his standard comments about their stretching, "Hey, next time, bring flowers if you're going to be doing that kind of thing." Everybody laughed, Jessica nervously.

Chris popped up and patted Jessica on the back. "Great workout today; you really pushed it. Think you can handle more of the same?"

Jessica smiled conspiratorially, "Absolutely!"

Chris stopped before reaching the door and turned back to them. "Oh hey Jessica, next time I'll bring the information about the weekend boot camps I was telling you about. A couple of those, and you are really going to be buff."

She smiled, "Yeah, I'd like that."

He left.

Steve, sitting there, she thought about telling him what happened. Then she realized he'd ask her if anything happened before, and she'd have to admit to not telling him. She thought he might change his mind and get mad at her, which she couldn't bear. If she was honest with herself, her real fear was that Steve would get angry and she wouldn't see Chris again, and she ached for him now. She told herself he had told her to tell him much later, so she just had to trust that he meant it.

She slipped from the room to take a warm shower. She could still sense her pussy vibrating from Chris's beautiful cock and feel his cum dripping out from inside her. As she thought about his beautiful tan body and enormous cock she masturbated to several more pounding orgasms.

As the weeks went by, they forgot about the workout at all. The minute the door closed downstairs, they were on each other. They made it a policy to play the workout music louder, just enough that they could still hear the downstairs door open but loud enough that they could moan without fear. More than once, Steve came upstairs to find them out of breath and sweating but assumed the workouts were taking their toll.

What Steve did notice was that Jessica did not seem to go as crazy for his cock as in the past. He had a decent 7 inches, and no matter how much crazy stuff Jessica did with others, she was always eager for him and praised his size. He assumed that the workout was changing her body in more ways than he figured, which was true.

Jessica became obsessed with diet and sticking to her workout regimen between sessions. Being so much older than Chris, she couldn't bear the idea of him tiring of her. Secretly, she sent him texts throughout the day, some sweet, some lustful, and others featuring videos. Chris asked her to masturbate all over town and send him proof, which she happily did. He became obsessed with her masturbating in public and more than once, she was caught filming videos for him. However, that didn't stop her from doing it again and again.

Every workout session became like Christmas, and she could barely control her anticipation. When she received Chris's text that the next session would push her to new limits, she practically collapsed with breathless excitement.

The night arrived. With Steve stowed away in the basement and Jessica already naked on all fours with anticipation. Chris poured lubricant on his cock and fingers as he walked towards her.

"Are you ready for something more? Something I have never been able to do with a woman before?"

She didn't ask or care what it was. "Yes!"

He knelt behind her and slid a finger into her ass as she sighed with pleasure. He worked the finger in deep and stroked her. His finger came out and was joined by a second. Both slid in and out of her. He could feel her close tight on him as he went to pull them out and he knew she didn't want them to leave.

"What do you want?" he asked.

"I want you to fuck my ass!" She hissed seductively.

Chris knelt behind and placed the tip of his dick at her hole. Slowly, he slipped the head and an inch inside.

She winced with pain.

He began to withdraw as his experience was that they couldn't handle it and asked him to stop. Instead, Jessica quickly reached back to his hip and pulled him towards her.

"Fuck my ass!"

Amazed, Chris smiled and pushed forward inch by inch until he was completely inside her. Unsure of what to do since he had never been able to do this before, he timidly moved inside her.

Jessica quietly growled at him. "Fuck my ass!

He filled her up once again, grabbed her hips and began pounding her with a vicious assault. The harder he thrust into her, the more rabidly she pushed back against him. All the while repeating, "Fuck my ass!"

The tightness of her hole and the passion of her response moved him to a climax much sooner than he had hoped. He exploded inside of her, grunting, which pushed Jessica over the top to the most incredible orgasm of her life. Uncontrolled, she screamed out with pleasure.

They were both in shock as they returned to earth with the sound of the basement door opening and Steve's feet running up the stairs.

"Is everyone okay?" he cried out.

As Steve entered the room, they were still scrambling unsuccessfully to put on their clothes. Jessica was on the floor, shirt half down with one breast still exposed. She had a tight grip on her workout shorts, which were stuck midthigh due to all the sweat. Chris managed to get his shorts all the way up, but there was no way to hide the massive partial erection silhouetted against his leg. They both looked at Steve in shock and horror.

To their surprise, Steve walked past them and grabbed the television control, turning the music down.

"Geez, that music was just awful."

They silently watched as he played with the remote, bringing up the link to the internet folders. He clicked a few files and finally arrived at the one he wanted.

"I was perfectly content until you two started playing the damn workout music so loud to cover your tracks and drowned out all the noises, which was so much fun to listen to."

He clicked a file and up popped a video of one of Jessica and Chris's "workouts."

The three sat down and Chris and Jessica watched with open mouths as Steve played video after video of all of their sessions.

When he was done, Chris nervously asked, "What now?"

"That's easy. You keep coming and working her out. She looks amazing! But you'll have to come 30 minutes earlier to have plenty of time for your actual workout and post-workout fun."

Dazed, Jessica walked Chris to the door.

"See you next time?"

He smiled, "Works for me."

As he opened the door, Steve called out, "Oh hey, Chris, be sure to let us know about those weekend boot camp trips you were talking about. I'm sure Jessica would love that."

Steve smiled, "They usually video those events, don't they?
