Skip to content As an only child, I naturally grew up close to my cousin Ashley. We were the same age, twenty-one. But during puberty, we drifted apart a bit. Ashley had always been more outgoing, flirtier, and more adventurous than I was, and it didn’t help that she’d earned a bit of a reputation in college as the known slut.
We still talked whenever our parents got together, but it wasn’t the same as when we were younger. That had changed recently as she’d hinted she wanted to go to the gym with me, saying she wanted to get in shape.
This morning she texted me. She got straight to the point and was even bold enough to send me a nude pic of her tanned ass.
It needs to be sculpted and pretty. Can you help me with that?
Sure… but you don’t have to send me nudes of yourself!
Woopsie 🤭
I could tell it was intentional.
I’d been going to the gym since I was sixteen, so I knew a thing or two about getting in shape. Ashley wanted to go late in the evening since it was her first time, and she didn’t want to embarrass herself, even though I assured her I’d guide her through everything.
We met outside just as the sun was starting to set. I shouldn’t have been surprised by her outfit. She wore tiny leggings that practically looked like underwear, with a seam riding right up her crack. Her sports top pushed her breasts up, making them look like two beach balls barely covered by a thin layer of fabric.
Ashley was a brunette with natural freckles scattered across her cheeks. Aside from her eye-catching bikini-worthy chest, she had a cute face with deep dimples and a straight nose that looked like a nose job. But I’d known her my whole life, and I knew she was all-natural.
“Nice outfit,” I said, clearly being sarcastic.
“What?” she asked innocently, twirling a strand of hair around her finger. “Don’t pretend you don’t like it.”
“This is a gym, not a nudist beach.”
She giggled. “You’re exaggerating,” she said, giving my shoulder a playful smack. “Come on, aren’t you excited? We haven’t had any real quality time together in years.”
She had a point, and truth be told, I was a little excited to finally spend some time with her, even if I wasn’t proud of her slutty behavior.
“So you want to work on your butt, right?”
She nodded eagerly and slightly bent over to show me her round globes. “Uh-huh.”
We started with squats. I showed her how to position her feet, how to keep her back straight, and how low to go.
“Like this?” she asked, sticking her ass out as far as she could while looking over her shoulder.
“Yeah,” I muttered, trying not to stare. “That’s … technically correct.”
I moved behind her to guide her posture. She bent her knees and lowered herself slowly, her leggings pulling tighter with every inch.
When I placed my hands lightly on her hips to correct her form, she smirked and deliberately pushed her ass back, right against my crotch. The friction of her firm ass against my bulge was quite sweet, but I tried to stay professional.
“Ashley,” I said, looking around us in case anyone was watching. “You don’t have to do that.”
“Do what?” she asked innocently, tilting her head.
“You know what. You’re making it hard to concentrate.”
“Is that what I’m making hard?” she teased, grinding a little more against me as she dropped into the next squat.
I clenched my jaw. “I’m trying to help you work out, not get a hard-on in the middle of the gym.”
“But you’re doing both,” she whispered with a grin. “Multitasking.”
As she lowered herself again, she suddenly stopped. “Ugh. My boobs are slipping out of this top. Can you hold them for a sec?”
I stared at her, trying to tell if she was serious. She looked back at me with a playful glint in her eye.
“You’re not serious.”
“I am. Just while I do a few reps. I swear, they’re about to pop out.”
I rolled my eyes but stepped closer, yet again glancing around to make sure no one was watching. Then I cupped her breasts from behind, keeping my hands steady as she dipped into another squat.
Her body moved slowly, up and down, warm against me. The weight of her breasts felt quite good in my hands, and for a moment, I wished she didn’t wear a sports top at all.
“You’re actually doing pretty well,” I murmured, trying to keep my tone neutral while I cupped her tits.
“I always do well when I’m properly motivated,” she said, giving her hips a small wiggle on the way up.
Next up were hip thrusts. I set her up with a padded bench and showed her how to position the bar across her hips. She got into place, shoulders against the bench, knees bent, and heels planted firmly on the ground.
When she started thrusting her hips upward, she let out a lustful moan.
“Unh…”
I raised an eyebrow. “Ashley.”
She did it again, this time louder. “Mmm…”
“Tone it down. You sound like you’re trying to get fucked.”
She looked at me and smiled innocently. “Why is it okay for guys to grunt like cavemen, but girls can’t make a little noise?”
“Because no one thinks a guy’s about to come in the middle of a set,” I muttered.
She giggled and kept going, thrusting up with exaggerated movements, her moans somewhere between teasing and downright dirty. A few people glanced over, but she didn’t seem to care. I kept my focus on her form, trying not to stare at the way her hips moved under the bar and the way her legs were spread.
“Alright, water break,” I said, needing a breather myself.
We grabbed our bottles and moved to the side of the room near the mirrors. I took a long sip, and she wiped her forehead with the back of her hand.
“How am I doing?” she asked.
“You’re doing fine.”
She turned around and looked at me over her shoulder. “Wanna check if I’m making progress?”
“It’s the first day. You’re not going to see any difference yet.”
“But I’m already sore,” she said, caressing the swell of her ass. “Just check. Squeeze it.”
I sighed, then placed a hand on her ass and gave it a firm squeeze. It was warm, tight, and soft under my fingers. I had never felt an ass like that, and I could only imagine how it would look if she continued coming here.
“It’s fine,” I said.
“Only fine?”
“Don’t push it.”
She laughed and walked ahead of me, hips swaying on purpose as we made our way back to the machines.
The next stop was the leg abductor. She sat down and spread her legs around the pads, slowly pushing them apart with a dramatic sigh.
“This one’s definitely my favorite,” she said with a grin. “I feel so… open.”
I knelt beside her, adjusting the settings. “Keep your back flat against the pad. Don’t lean forward too much.”
She nodded, pushing her thighs open again. Halfway through her set, she winced. “Ow. That inner thigh again.”
“Not this again,” I muttered.
“I swear, it’s pulling or something. Just a little higher up this time.”
I narrowed my eyes, but she looked genuinely bothered, at least on the surface. I knelt beside her and pressed my thumbs into the inside of her thigh, just above the knee. I moved slowly, working the muscle, then moved my hands a little higher.
“Tell me if it hurts,” I said.
She stayed quiet, her breathing deeper. As I massaged upward, I caught a faint scent, sweet, musky, unmistakably aroused.
I paused, eyes flicking up to meet hers.
“You good?” I asked.
She nodded, biting her lip. “Feels better when you do it.”
We finished off with a light jog on the treadmill. Ashley got on the one next to mine. Her skin glistened with sweat, her boobs bounced and jiggled, and her sports bra clung tight. Droplets slid down the curve of her breasts, drawing my attention even when I tried to look away.
Then it happened, mid-run, one of her boobs popped out of her bra.
She looked over at me without slowing down. “Told you so.”
I stared for a beat before looking away. “Jesus, Ashley.”
She laughed and tucked it back in, totally unfazed. “You think I don’t know how these things behave?”
Once we wrapped up, we grabbed water again and sat on one of the benches near the stretching mats. It was quiet, the lights slightly dimmed now that it was late. We seemed to have the place to ourselves, except for some ladies stretching in the corner.
“So,” I said, wiping the back of my neck with a towel, “what did you think?”
“I liked it,” she said with a smile. “Honestly? I wanna come back. It was fun.”
Despite her constantly teasing me, I was glad she liked it here. We sat there for a moment, catching our breath. Then her eyes dropped to my shorts. I realized I was still semi-hard, not that it was easy to hide.
She reached out and brushed her hand along the front of my shorts. “You’re still turned on?”
I looked around but no one else was in sight. “Yeah, because of your teasing earlier …”
“I miss this,” she said. “Not the gym, I mean … us. Hanging out, playing and teasing each other. We used to have so much fun together.”
“We’ve never been that close,” I reminded her.
“So? There’s a first time for everything.”
“What are you implying?”
She leaned closer, so I could pick up the scent of her musky arousal along with a little bit of her sweat. “Have you ever thought about doing something crazy here?”
I looked at her. “Like what?”
“I don’t know … like fucking?”
I blinked. “You’re insane.”
“No, I’m serious. I scoped out a spot earlier, behind the back wall by the dumbbell racks. There’s no camera back there.”
I stared at her, wondering if she was actually serious, but her eyes said yes.
“Ashley, this is a public place. We’re in a gym. We could get caught.”
“We won’t,” she said, brushing her fingers along my thigh. “If we’ll be quick.”
“Also,” I said, pulling slightly away, “we’re cousins. First cousins.”
She rolled her eyes and giggled. “So what?”
“What do you mean, ‘so what’? That’s a pretty big deal.”
She leaned in again and lowered her voice. “You think we’re the only ones? You’d be surprised how many cousins hook up. Some even get married. It’s not illegal in half the country.”
“That doesn’t make it normal,” I muttered.
“It’s normal if we want it to be,” she said. “You think I haven’t thought about it? About you?”
I swallowed hard. My whole body was still warm from the workout, my heart beating faster now for entirely different reasons.
“I missed you,” she whispered, hand moving slowly over my thigh again. “You feel it too, don’t you?”
I didn’t answer right away. I looked away, trying to summon some reason, some anchor to pull me back. But then she kissed my neck, just below the ear.
My resolve cracked.
“Fuck,” I said, knowing I couldn’t let such an opportunity slip. “Let’s do this.”
She smiled. “Come with me.”
I followed Ashley to the back corner of the gym, cock throbbing in my shorts.
“Quick,” she whispered, glancing around before dropping to her knees in front of me.
Before I could process what was happening, she tugged my shorts down and took me into her mouth, her lips sliding down my length.
“Wow,” I said, bracing one hand against the wall.
She looked up at me, eyes locked with mine as she slid me deeper and deeper for every bob. The sight of my cousin on her knees, her lips stretched around me, was more erotic than anything I’d ever experienced. She slobbered all over my cock, droplets spilling all over my shaft. I was surprised by her skills and how well she sucked.
She came off with an obscene pop, wiping the spit from her lips. “Let’s fuck.” She stood up and turned to face the wall.
She pulled her leggings down just enough, exposing her perfectly round, tanned ass that I had seen this morning. She braced herself against the wall and looked back at me expectantly.
I hesitated for only a second before positioning myself behind her. It wasn’t like I could resist this horny girl now. I pointed the head against her moistened lips, rubbing the sensitive head against her till I found her hole. I slid inside her with one firm thrust, causing her to gasp. She was as wet as her mouth, and it felt like heaven the way her pussy hugged me all the way.
“How’s my ass looking from there?” she asked breathlessly as I began to fuck her.
I gripped her hips, watching the way her flesh bounced with each thrust. “Fucking gorgeous,” I groaned, unable to tear my eyes away.
Ashley moaned loudly, the sound echoing off the walls.
“Shhh,” I told her, glancing nervously toward the main gym area. “Someone will hear us.”
“I can’t help it,” she said, pushing her round fuckable ass back against me. “It feels so fucking good.”
I reached around and slipped my hands under her sports bra, cupping her breasts as I continued thrusting. “Oh, so now you want to grope my titties?”
“Shut up,” I told her, making her giggle.
“Hmm, you’re really stretching me,” she said. “I love being bent over like this.”
And I loved having her like this in front of me, her back arched, her ass pushed against me and her pussy walls hugging my shaft as I rapidly slid in and out of her.
“We need to hurry,” I whispered, feeling myself getting close. “Someone could walk in any second.”
The danger only seemed to excite her more. “That’s the exciting part, duh,” she said before turning back to moaning like a pornstar.
There was no idea telling her to shut up. It just made me slam into her harder and faster so the “clap” rose higher. I was steadily reaching my orgasm, the combination of risk and forbidden pleasure pushing me closer and closer to the sweet peak.
“I’m going to come,” I told her.
“Don’t you dare pull out,” she demanded.
I didn’t have any plans. I seized her hips and thrust deep into her firm cheeks. I exploded inside her with a muffled groan, burying my face against her neck to keep quiet. Rope after rope of cum filled her pussy until she was thoroughly soaked in my seed.
“Gosh, you pumped an entire bottle of buttermilk inside me,” she said with a joyous giggle.
“That’s the sweetest pussy I’ve ever fucked,” I muttered, giving her slow, shallow thrusts to drag the orgasm out.
“Told you you’d like it.”
When I pulled out, thick rivulets of cum clung to her and spilled down onto her leggings. I tugged my shorts back up and grabbed some paper towels from the nearby shelf, helping clean her up. Then I gently pulled her leggings back into place.
I glanced around the gym, still breathing hard. “Did anyone see us?”
She shrugged like it didn’t matter. “Who cares? That was some amazing sex.”
“Alright. Workout’s over. Let’s head home.”
As we walked toward the changing rooms, I spotted a woman in her mid-thirties stretching nearby. She glanced up and gave me a knowing look. She’d definitely heard us.
Just before Ashley and I split for the locker rooms, she rose on her tiptoes and kissed me on the lips.
“Geez, why are you blushing?” she asked with a playful smile.
“Nothing,” I said, shaking my head.
“I really loved working out with you,” she said. “We’re doing this again, right?”
“For sure,” I said, and I couldn’t lie. “This was a day I’ll never forget.”
We exchanged grins, then finally parted ways.
The end.
