Her Trainer Has Been Working Her Hard
And getting far more than he was getting paid for.

There are many ways to discover you are a cuckold. There are those who’ve always known, filled with an intense desire to see their wife or girlfriend pleasured by another man. Then there are those who are drawn into the lifestyle by a wife with wanderlust and a craving for new and exciting experiences.
Then there is me.
I found out I was a cuckold when my naivety took me to my wife’s gym last Sunday morning. She’s been on a fitness binge the last few months and is looking incredible. The only downside is that she’s been too tired to have much sex.
I figured it was just her body adapting to all the extra effort she was expending and feeling a little self-conscious of how my own physique had flagged over winter, I decided to head down to the gym to join her for her Sunday morning workout.
Only when I got there, there was only two cars in the carpark, my wife’s among them and the place looked abandoned.
Sunday clearly wasn’t a popular choice for fitness enthusiasts I figured, as I let my self in through the still unlocked front door.
There was no one on the front desk, so I went for a wander. Halfway down the hall I recognized my wife’s voice.
“Please,” her muffled groan carried through the gym. “I can’t take it anymore.”
I quickened my pace, stopping only when I reached a set of doors leading into a large workout room. They were ajar and a sliver of light was filtering out into the hall.
I should have yanked open the door, but my curiosity got the better of me. It didn’t sound like anyone was lifting weights in there. Peering through the crack, I spotted my wife laying on a weights bench, both hands holding the bar. She was wearing a tight set of spandex booty shorts and a zip front sports bra.
Her legs were bent at the knee, her feet resting on the bench while a man stood over her at the head of the bench, where you would expect to find her spotter.
Only he wasn’t helping with the bar, it was still resting on the stand.
No, her incredibly fit trainer was leaning over the bar, and had his hand resting on my wife’s pussy.
Well, it was hardly resting. He seemed to be working his fingers back and forth, pushing her spandex down into her sex. The front of the bright pink spandex had a damp patch on it as he rubbed at her prominent camel toe.
At first I thought she was being taken advantage of, but as I watched she pressed off the bench with her feet, grinding her sex into his hand.
“Please,” she begged again. “More, I’m so close.”
Her trainer eased off her pussy as she tried to grind herself to an orgasm, his hands moving to her breasts where he teased at her nipples through her skintight top. Even from here, I could see just how aroused she was. They were both poking through the thin fabric.
“It’s only been a day,” he replied, as he tweaked my wife’s nipples.
I knew I should burst through the door, but part of me wanted to see how far things would go.
“I know Marcus, but I’m addicted,” my wife replied, her hands leaving the bar in search of a different rod.
Marcus stood over her head, his shorts tenting obscenely mere inches from her nose. He had to be hiding a monster in there.
My wife’s hands found his thighs and rose straight up them, sliding between the baggy fitting shorts and his skin before wrapping around his shaft.
She was jerking him off, right there in front of me. Her hands working back and forth beneath his shorts as she licked her lips hungrily.
Who was this woman? I’d never seen her so openly hungry for sex.
“What about your husband?” Marcus asked, taking a firm handful of my wife’s breast.
My wife kept stroking him beneath his shorts. The sight of her dainty hands working his shaft was making me hard. I knew I should be jealous, or angry, or something, but her raw unbridled lust was turning me on. I could feel my own excitement growing by the second.
“I haven’t let him touch me all week,” she panted as he wrapped his fingers around her nipple, pulling at it through her shirt.
Her words hit me like a punch in the guts. So, it wasn’t just our busy schedules, she’d been avoiding me on purpose, but why?
My wife answered the question for me when she yanked down Marcus’ pants.
His hard cock sprang out of them, and it was every bit as big as the rest of her very fit trainer.
Glee filled my wife’s eyes, as she wrapped both hands around it.
Marcus squatted a little, resting that huge weapon on my wife’s face, and it reached her damn chin.
No wonder she was mesmerized. It had to be twice the size of mine, and much thicker.
My wife, slid back along the bench until her head cleared the edge, allowing her to maneuver the thick head to her lips. She licked around the bulbous head before taking it in her mouth.
She attacked him with gusto, stroking with both hands as she slurped and sucked at him.
I couldn’t help myself. I stood there at the door and dropped my pants, stroking myself as my wife gave the hottest blowjob I’d ever witnessed.
She’d never shown much enthusiasm when sucking me, perhaps it was a size thing as she was worshipping Marcus.
Her trainer stood over her, thrusting as much of his dick into her willing lips as he could fit. From the grin on his face, he was thoroughly enjoying himself.
Who wouldn’t be? My wife was hot as hell on a normal day, and today she was acting like a sex-starved nymphomaniac.
After a few minutes of enjoying her attentions, Marcus pulled away from her, and my wife flailed after his retreating cock.
“Hey,” my wife groaned, “bring that back.”
“Oh, you’ll get it alright,” he replied. “But first, I want to see those tits.”
My wife smiled coyly as she reached for the zipper on the front of her sports bra. Her chest rising and falling with every breath.
Slowly, sensually she peeled the zipper down, her cleavage forcing the two halves of the bra apart. The zip reached the hemline and the sports bra popped open; my wife’s taut breasts burst free.
“Do you like them?” She teased, “my husband paid for them.”
My jaw dropped as she teased her lover. I didn’t know what to do, but I couldn’t pull my eyes away. I watched as Marcus moved to the end of the bench, my wife’s legs falling open to meet him. With one hand he guided his girthy cock to her waiting pussy, with the other he grabbed a big handful of my wife’s breast.
With a single thrust he buried himself inside her.
I watched as my wife arched her back, her pleased moan filling the gym.
Marcus bent over her, his hands mauling my wife’s chest as he thundered into her. The slap of his flesh against hers filled the gym as my wife grabbed the bench’s vertical bars for support. The foreplay was finished and all she could do was hold on for dear life as Marcus pounded her into the bench.
I stood there in the doorway, feverishly stroking as I watched him use my wife.
They weren’t making love, she was being used as his fit little fuck toy, and she was clearly loving every minute of it.
“More,” she cried as she pushed back against his thrusts. “I need that big horse cock.”
Marcus grunted his approval as he increased his speed.
No wonder my wife was exhausted, if this was what she’d been up to every day. I was amazed she could still stand or sit for that matter.
Marcus’s thrusts grew more erratic, and as the muscles in his ass tightened up, I knew what was coming next.
He was going to come.
My wife sensed it too, but instead of pushing him away, she wrapped those long legs around him and held him tight. She wanted him to fill her pussy.
I exploded as Marcus did, spraying my load all over the floor as Marcus filled my wife with deep powerful strokes.
I bit my lip to hide my groans as my wife climaxed before my eyes.
She looked so damn fuckable pinned tight against the bench, her hulking bear of a trainer buried inside her.
As she came down from her orgasm, Marcus pulled out, made his way around the bench and slid his cock, still coated in both their juices, back into her mouth.
To my amazement, she took it eagerly cleaning their combined juices off it. Perhaps it was my imagination, but I swear I could see his load starting to leak onto the bench.
But my dutiful wife paid it no heed, sucking and slurping at Marcus until he was rock hard again.
Marcus looked down at her, a big grin on his face.
“Looks like someone is ready for another set?”
My wife grinned from ear to ear. “Yes please.”
“Maybe two,” Marcus replied as he flipped her onto her stomach and pulled her to the end of the bench.
Before I knew what was happening, he was back inside my wife, one hand on each of her well-rounded ass cheeks enjoying the fruits of his training.
“Well,” I groaned my hand returning to my spent cock. “Looks like it’s going to be a long day.”
