Lust Experiment at the Gym (MF) (gym) (quickie) XXX stories

After a long work day, Tim was hoping to get his stress and frustration out at the gym. He was so ready to sweat, he had to double back to the front desk guy who was handing out a new sports drink. The disinterested employee said, “boss said to give this out to everyone to try,” with a shrug. While changing, he tried the drink and was surprised to find he liked it.

Walking to his preferred treadmill for a warmup, his eyes fell on every girl he passed. Tim was aware the number of attractive girls at his gym usually, but suddenly his eyes felt magnetized to the tight work out clothes and tighter bodies. When he starting dreaming of licking beads of sweat of some bouncy tits, he shook his head to refocus on his work out.

Tim completed his warm up and retreated to a corner for his workout. During his sit ups, a gym regular, Misty, moved nearby for her leg work outs. She was always cute, but today, he was more aware of her body. Her fluorescent sports bra propping up her milk chocolate tits, and a luscious thighs straining in the workout, her juicy ass flexing in her short, tight shorts. She smirked at him over her shoulder while dipping to deep squats, eyeing below his waist.

Tim glanced down, embarrassed to see his shorts tenting. When he looked back up, Misty was walking over to make her move. “Hey, were you checking my squat form? Can you watch up close to make sure I’m doing it right?” His cock openly straining against his shorts, he nodded and started to stand up. “No, stay down there.”

Misty straddled Tim’s waist, allowing him the view from below. Her shorts hugged her ass close, but still allowed enough room to allow a peek for Tim. And then she squatted, her curvy ass lowering tantalizingly inches from his face. He watched a couple squats, pressure and lust building while inhibition dropping, before pressing his face forward into her dropping ass. Misty giggled as she smothered Tim’s face in a deep squat. He breathed deep, her face buried into her shorts.

She lowered, straddled Tim on her knees, and stroked his throbbing cock under his shorts while whispering, “nobody seems to be looking.” Hidden from view behind some unused equipment, Tim peeled down Misty’s shorts and pulled her panties to the side, briefly basking in her radiant warmth and glistening wetness before burying his tongue.

For a minute, they continued quietly in their corner with Misty stroking and Tim licking, until Misty straightened and adjusted her clothes. “Meet me in the girl’s showers now!” And she hurried off. Tim waited for a beat, adjusting his pants to hide his erection, before taking off after her.

Tim refused to look around the gym, to avoid catching eyes of people who might have seen their partially hidden display or where he was going. But in truth, the other gym guests wouldn’t have minded, as something was simmering in all of the guests. Without looking, Tim passed plenty of people getting more flirty and tentatively more handsy around him. In the locker room, he ignored any looks, missing the eye-fucks he was getting. Finally, he found Misty in the shower, naked and glistening in the spray, and ripped off his clothes to join her.

Bodies pressed together in the spray, their lips met in a lust filled, sloppy kiss while their hands explored. Tim moved his kisses to her neck and gave her ass a smack, while Misty stroked his cock before falling to her knees to savagely suck his cock. He drove her back against a wall, pinned her arms up and fucked her mouth. Misty’s eyes lazily closed in contentment while her throat was filled.

Tim backed out to let her catch her breath, but Misty stood and bent at the waist with a “take me!” With no hesitation, Tim plunged deep into her pussy. Misty gasped and begged for more, driving Tim to grab brown hips and thrust harder. “You like that?!” He called. Misty turned over her shoulder and moaned back. “I fucking love it. Harder!! Spank me!” Tim was happy to oblige, until Misty was pressed up against the wall and cumming over and over on his cock.

Tim grunted, “fuck, I’m gonna cum!” His mind went delirious at the feeling of Misty’s slit, the sounds of their bodies mashing together against the wall in the shower. He tried to slow down, but Misty expertly bounced her ass back against him and couldn’t hold out longer, and exploded inside her.

Tim felt relaxed and happy, but his horniness did not subside and his cock stayed hard. Wide-eyed, Misty lowered Tim to the floor and climbed on top, riding him in cowgirl. After a loud, shaking orgasm, Tim lifted and pinned her against the wall, fingering her until her eyes rolled and her body quaked from pleasure. “I want your cum in my mouth this time!” Misty kept playing with her throbbing and slutty pussy while Tim fucked her face until he flooded her mouth with his cum.

Both dazed, but still horny, they wondered if they should scrap the rest of the workout and go home together. That plan lasted until they left the locker room and finally took in the scene on the gym floor.

“Looks like this batch is a success.” A watching man in a lab coat said, shaking the hand of his neighbor. “Excellent work, sir. And great choice on this gym. The test subjects will certainly be fun to watch in this observation.” The other man nodded. “This batch will be potent. I wanted to make sure the subjects had the physical stamina to last. Let’s see how they do.”
