Running fisting club

Erotic short story from the environment of amateur runners from 10% according to reality :). Erotic short story contains sexual themes and is intended only for people over 18 years old. Dedicated to my friend Katka 14.8.2025

-

My name is Gábina. I have a sedentary job and now and then my weight will jump up to a few extra kilos. I know right away that I need to put in more work. Lately I've been enjoying running. I started with a 3 km Indian run and gradually managed up to 8 km. Running alone is fine, but it's easier with more people. My almost 40-year-old friend didn't satisfy me. His knee hurts and he refused to run with me for the last 2 km. His wife doesn't really want to let him run with me anyway. So I decided to go for a professional and signed up for a running club for women. 10 lessons for a total of 2400 CZK.

Trainings are on Tuesdays from 6. We start in the Kunratický Forest in Prague, where we change clothes in nature. We hide our city clothes in a small backpack. The group is for girls only. There are 10 of us. The youngest of us is a boy – Pavel, a student at FTVS and our coach. He is very handsome and hates 2 things. When we talk at his explanation and when random male runners come up to us and disrupt his alpha male hegemony.

During the first training session, he had us get in line and took a long, deep look at us. It was exciting, and I was afraid I was blushing. So I lowered my eyes so as not to attract attention. The speech had gone on for a while, and Veronica and Simone occasionally made a joke and giggled. Paul reacted reproachfully.

“We pay attention when teaching running. You'll miss valuable advice and then you won't be able to catch your breath.” I thought to myself (Kataka): 'This guy loves his job.'‘

After running 2 km he let us rest while he explained and corrected our running style. Sometimes he touched our thigh and embarrassed many of us. I figured I'd make it a little harder or easier for him and next time I came in a skirt.

He didn't notice me during the entire training. Only at the end did he say: "Girls, go away. Gabina, you stay." The girls looked at me curiously.

When they left, he told me: “Stand with one foot forward and the other back”. He grabbed me by the inner thighs and began his explanation. I don’t know if I blushed or if my forehead was dewy. I was all sweaty after the run, so luckily it wasn’t noticeable. I was completely frozen.

“When the left goes forward, the right engages like this… , hands hips like this.” He guided parts of my body and his fingers acted very skillfully. I gradually relaxed and when he accidentally caught me by my panties, I acted as if nothing had happened. He moved his hand there more often and the sports interpretation smoothly turned into stroking. He pulled down my panties and laid me on his jacket. Then he pulled down his elastics, under which his penis had not been visible for a long time. I was quite excited, so he shamelessly pushed it into my vagina right up to my testicles and started thrusting powerfully.

“"Be careful, I'm not taking anything," I told him in a low voice about my situation with contraception.

He was horny and it only took a moment before some of his testicular filling was on the floor next to me.

“"It's a shame we don't have a condom. I'd give you another chance," he sighed.

Then he thought and added. "You were unprepared, Gabina. That needs to be punished."“

He pressed his penis, moistened with bodily fluids, against my anus and waited for me to react. He took my silence as consent and pushed his glans into my external sphincter. He stroked my pussy for a while while gradually pushing it all the way inside my anus. He let me inhale and exhale a few times and started thrusting. We both sighed and moaned. He varied the pace and strength. Sometimes he pulled it out all the way and looked at my open anus. I was there before he did and my ass started to literally suck it in. A moment later my ass was already filled with his warm semen. It started to flow out as soon as he pulled out his penis.

“"You have a nice ass and a nice ass," he complimented me.

I smiled. I wanted to praise him too, but often a smile or a laugh from a girl is the best praise for a boy.

He ignored me for the next 2 training sessions and talked with Simona and Veronika. I was offended, but I kept it to myself. I'm not gonna beg anyone.

On the fourth run, after the running instruction, he whispered in my ear. “Would you like to come to my place after training?”

I blushed with shame and the audacity of his not noticing me before. But then I nodded.

"Take some sports clothes with you," he added and ran on.

I (Gabina) arrived at his house with a backpack in running clothes. So in the living room in the biggest room there was no furniture but 3 treadmills and 3 bike trainers.

I saw Simona and Veronika on the treadmills. They were all flushed. They were wearing nothing but sneakers and bodysuits. There was a dildo sticking into their vaginas from behind the treadmill. Panting, they cheated on me and kept on running.

“"Change into sports clothes." Pavel didn't move an eyebrow.

I (Gabina) took off my pants, sweater and shoes and put on a T-shirt and sneakers.

“"Panties down," Pavel said sternly.

I didn't say no (to Gabina). He took a moment with my trimmed pussy and was already leading me to the belt. There he gelled my pussy and inserted a dildo about 10 cm deep into my vagina. It was thicker than a normal penis and I moaned a little. Then he lowered the trainer and I started moving right away so he wouldn't stick himself in deeper. I could feel it digging into me with each step. It was a delight. I was done after less than a minute so I jumped off.

“"It wouldn't work that way". Look at Simona and Verča, how honestly they work", Pavel scolded me.

He put me on the belt and gave me some speed. I had about 20 cm of him in me like the girls and I started to pant a lot while running and fucking. Paul, in sweatpants, walked around us and occasionally gave us a complimentary slap or pat on the butt. His full stick was visible through his shorts.

“"That's enough," he turned off our exercise machines and I barely made it.

“"Now relax your inner body a little. Lubricate your asses."”

He sat us on bike trainers with nice dildos made of realistic leather instead of a seat. Unfortunately, he put them up our asses.

“The vibrator is powered by your bike’s dynamo,” so go for it. After a few kilometers of standing, we wanted to give our legs a little rest and pushed our asses deeper into the vibrating penis. Sometimes he came to one of us and pressed our asses a little more until we started to whimper. While doing so, he stroked our clitoris and ordered us to “Suck, suck more.” He made us all cum.

He let us breathe a little. He ran into the room and brought 3 big black anal plugs.

“"Lube up your ass again and we'll do some squats on them."”

We gradually sank deeper and deeper. Anal pins they were pretty big and they hurt. If Paul thought we were fooling around with raised voices he called us to him and shoved his cock up our ass for a while.

It was a relief compared to the artificial pins, but we didn't want to disappoint him, so we tried on the pins too.

Simona was the first to get it all in. He left it in her ass and took her vagina with his penis. Simone was cumming almost immediately. Veronica wasn't doing well. Neither did I.

“"Girls, go together and help each other," Pavel urged us. "Caress the other one and push the peg into her ass.".

We stroked and pushed each other with Verča until she did it too and Pavel took her aside. She came and Pavel soon after into her pussy. Then she was allowed to take the pin out.

Pavel came to me and said, “Kneel down!”

I thought I was supposed to suck his cock, but he added: “On all fours!” He took the plug and moved it around in my ass. For a moment I (Gabina) thought I couldn’t take it anymore and then the plug slipped in. I had a 6 cm wide plug stuck all the way in my ass. But it hurt less than when he was thrusting in because the sphincter was now surrounding the narrowed cervix.

“"So that it doesn't become so easy for you," Pavel said as he put on the penis extension. Penis cover expanded his already large penis by two inches. He rammed it into me with quite a force. I was on a pole, actually two poles. He almost couldn't even fit inside me, he must have pushed a lot and I knew I could take more than I thought. My ass and cunt were completely loose and wet, yet both holes were filled to bursting. After my second orgasm, Paul came too. He took the plug out of my ass and shoved it into my vagina. Then he and the penis attachment pushed into my asshole. He drove it in nicely and pulled it out quickly so he could see my asshole properly stretched.

“Spread your ass with your hands,” he ordered me. “Do it!” he slapped me hard on the ass with his palm every time I slacked off.

His third orgasm didn't come until about twenty minutes later, so he was stretching my ass for a long time before he squirted. After that time, my asshole was pretty stretched out and pretty beat up, too.

“"Okay, now relax in front of the mirror. Kneel down with your butts facing the mirror and push on command.".

“Now” we started pushing and our asses opened so that you could see inside them. Pavel looked at them and nodded approvingly.

This was repeated about 30 times before he ended the training with the words "You can get dressed.".

Only now I (Gábina) started to perceive my surroundings. Evaluate what actually happened and whether I liked it. The girls looked like it was not their first training. I realized that I really liked it. I found my ass bleeding slightly, but the feeling of satisfaction lingered.

After the next training Pavel called me if I wanted to go running with him the next day. I agreed. We ran for an hour and it was pleasantly warm. After the workout we bought a liter of wine at a nearby forest restaurant and found a picnic spot. It was a warm summer evening. During the toast, Paul reached under my panties as if nothing was wrong and started stroking me. We acted like it was nothing. My pussy gradually became wet. He laid me on my back and began to push his fingers inside me, licking me as he did so. When he pushed his palm all the way down to my finger knuckles, it spread me a lot and my pussy began to contract in orgasm.

I wanted to reciprocate by reaching for his cock. He just smiled and shook his head.

“"I still want to play with you.".

We talked for a while and sipped our wine, then he pushed his hand inside me again. Now with more determination than before. I whimpered. I could tell he wanted to shove his whole palm into my pussy. But I was thoroughly turned on and willing to sacrifice a little pain for the knowledge of what else I could endure.

His hand went all the way in. My vision went black with pain and I thought I was going to burst. I wanted him to take it out, but he held it there for a moment and licked me. And then it felt as strong as ever and my vagina tightened around his palm a few times. He smiled with satisfaction and then took it out. I was shaking all over and it took me a while to get back to normal.

“"You don't want to do it," I asked?

He put the butt plug in my hand and said, "I'll keep it for next time. Next time we'll do it with your ass, so practice.".

I (Gabina) was shocked again, but everything was so intense that I left this option open in my soul.

...

I had a week and I wanted him to be happy with me. So I take training to heart. But it wasn't possible at home. I live with my parents and they weren't used to me locking myself in my room. Luckily it was warm outside. So every day after work I always went for a "run" in the forest with my backpack. In addition to a drink, my backpack contained a peg and lubricating fisting gel.

I know the Krč forest and I know where no one goes. I put on an anal plug in the forest and stroke my cock. Inserting the entire anal plug hurts. I want to really get it moving. I imagine Pavlo's hand in my ass. At the same time, I look to the less covered sides to see if any random walkers or runners are approaching. But the third training session went a bit... awry...

...

Bořek had just returned from an internship in the USA and they went for a run as usual. “Let’s go halfway – to Krčský les. Let’s try something different,” Tomáš suggested, because they usually went to the Hostivařská dam.

“"Ok", agreed Borek.

They didn't go on the beaten paths, but they made a proper outdoor trail. They ran where it was the roughest. Around a bend in one of the less accessible spots about 20 yards ahead of them, they saw a girl kneeling down and lifting her bare ass up and down, jerking her pussy in the process.

“"Lie down," Tom responded quickly and we both fell to the ground quickly. We were both in shock and trying to gather our thoughts.

“What do you want to do?” I asked Tom.

“"We're going to fuck her," Tom said without hesitation.

“"No, it's not working, man," I said to myself in pleasant shock. And while Tom was clear, the imaginary devil in me started a tough fight with the imaginary angel.

“"What, is it? Don't you like it?" Tom insisted.

“Well, she's pretty, but I can't”?

“"Why, man, such an opportunity comes 0 to 0.1 times in a lifetime, we can't let it go," Tom said.

“Well, I have a wife,” I said, half-heartedly, even though my dick was starting to tingle. As a side effect of the blood draining into the lower levels of my body, I also felt like I couldn’t concentrate on solving the problem as well as I usually did.

“"I'm going, you can join or just watch," Tom said ultimatum.

“Dude, don't we have condoms anyway?” I said to Tom as a last resort. I hadn't had to choose yet.

Tom unzipped the tongue of his sneakers and pulled out two condoms.

“Dude!” I gasped in disbelief. In disbelief, what a brutal device this was, and also because my hopeful excuse was suddenly in tatters, and now the list of “pros” added the fact that otherwise I would be an indecisive jerk.

“That’s the Nike Lunar Glide – Fuck!” Tom said with satisfaction. “So my wife doesn’t find it. They don’t sell the official Fuck version, but if you ask for them, they’ll send them to you.”

I was so trained and at the same time I wanted to see how far it would go that I turned off all my defence mechanisms and let the situation take me. My conscience and perhaps my consciousness went into a whole new mode unknown to me: the axe. Like a Neanderthal, I put off responsibility and taking stock, figuring that maybe later I'd figure it out.

...

Gabina noticed 2 boys approaching her. They were looking at her. They saw her. She quickly pulled out her stake, pulled up her pants. She put the stake in her backpack and waited.

“Hello,” Tomas greeted her. Boreka immediately followed. She greeted them too and they said each other’s names. Tomas wasn’t sure what to do and whether Gábina wouldn’t reject him, but he decided not to ask questions or talk. He sat down next to her and reached straight between her legs.

Gabby flinched. She was scared, but she was pretty well behaved. She didn't want to run and waited to see what the boys would do. Tomas continued to stroke her. He went under her panties. She let go and started stroking his cock. She smiled at Boris and he joined in the stroking. Tom pulled down her panties and was about to lick her.

“"No," she said, and the boys stopped.

“"I'm already excited enough, just stick it in there," Gabina said meekly.

Tomas put on a condom while thinking how to make it so that Bořek could have access.

“"Sit on me," he said.

Gabina sat on top of Tom and took a condom from Bořek. She put it on his penis and took it into her mouth. For the first time, two guys were touching her. She was all freaked out and tried not to scream.

“"Come to my ass," she said to Bořek.

“Come change,” Tom told me.

Gabina handed Tom the gel and mounted Bořek in anticipation of Tom's cock in her ass. Tom joined in after a moment. They both pounded into Gabina and she soon came. The boys were still a little shocked so nothing yet.

They paused for a moment and Gabina said, "I need to work out my ass. You can both go there more than once."“

That turned the boys on. Tom went down under Gabina again, this time into Gabina's loose ass and Borek from behind. It took a while for Borek to get into Gabina's ass, but eventually he slipped in too.

Gabina sighed loudly. The guys started to thrust one after the other. The two pee-pees took turns in her ass, one, the other, sometimes both at the same time, depending on the synchronization of their thrusts. Droplets of sweat were running down all over them and they had a hard time holding back their moans. Gabina was still jerking off her pussy. Gabina's third orgasm really excited the guys. They started to thrust hard and a moment later they were also done.

“"Show us your ass," said Tom. Gábina knelt in front of them, thrust her ass out at them, and pushed. Her anus was pretty loose, and her ass was looking at the guys, a few centimeters wide.

They were so excited that they wanted to do it again. Bořek lifted her up onto a stand. She grabbed him around the neck and rested her legs on his forearms.

“"Now please put both cocks in my pussy," she whispered.

Tom approached Dave from behind and they filled her pussy solo. They changed positions a few more times before they all got fucked. They exchanged numbers and did not rule out another similar encounter.

...

Gábina arrived at Pavel's place with her self-confidence boosted and a properly prepared relaxed anus. The presence of Verča and Simona did not upset her any more. The competition even turned her on in a way.

“"Kneel behind you and try to spread your asses as much as possible," Pavel instructed them.

We knelt down, Verča, me and Simona behind me. So I (Gábina) tried to put my hand in Verča's ass, Simona in mine. Pavel started to fuck Simona, alternately in her pussy and ass. Verča also had to practice, because my hand got into her quite easily. Just like Simona's in mine. After a while, we always switched as girls and Simona could also handle the hand.

“"Roll your palms and try your fist. You should be able to handle my hand too," we received another instruction from Pavel. It was a bit more difficult, but our asses gradually got used to it. The best part was fucking with Pavel, when our asses got a little rest and tasted our pussies for a while. We could use our other hand to caress each other's pussies, so from time to time one of us climaxed.

“"Kneel down and stick your butts out," Pavel commanded.

He turned on the camera and put us on widescreen TV so we could see each other. There were holes in our asses about 3 cm in diameter. Pavel knelt down in the middle of Verča and shoved it into her ass. As he did so, he pressed his palms between Simona's and my halves. We breathed heavily, quickly and briefly as his palms sank deeper and deeper and tightened our asses more and more. Our foreheads were frowning with pain and excitement.

After a moment, Paul's palm slipped all the way into me. I screamed in pain and pushed his hand away. He slapped me hard on the ass, switched me with Vercha and to my relief rammed his cock into my ass. Now Verča and Simona were moaning again. His palm got into Simona too. She tried to hold on to him for a while, but she also had to take her hand out right away. It was too big. So she got her ass kicked and I (Gabina) took over.

This time his hand got inside me faster and I held it in, even though I screamed out loud. He put his palm out and in and I felt my asshole loosen up. I thought maybe my ass was going to burst. Every time he pulled his hand out, I sighed deeply. I squeezed and released the sphincter again until a large open hole began to peek out at me from the recorded video on the TV. Simone was in a similar position. He put his cock in me again, alternating between my vagina and asshole.

Vercha couldn't manage his palm. He put it on his back. He connected her ankles with a spreader bar and pulled her legs to the collar at her neck so that her vagina and anus were exposed. Into her ass he inserted inflatable anal plug and put a chastity belt on it so it wouldn't fall out.

He put Simone on his right and me on his left. He always put his palm or fist sharply into my or Simona's ass and with his other hand he slapped Verča on her ass or genitals with a 3 strip whip (Persian reprimands) or she's been blown by an anal plug. All 3 of us screamed, probably Verča the most. Our loose and slightly swollen anal holes made squishy noises when quickly pulled out and retracted by Pavel's hands. I (Gabina) was a little embarrassed at this. She felt like a slut, but it was worth it.

I stopped counting how many times it came to me or the girls. Then he swung all 3 of us over onto the booster seat and Vercha's head off the seat. He rammed his cock into her mouth until she gagged, and in the process, he fucked a stake in her ass. He took Simone and me alternately with his hands and his penis. The penis was a relief from his hand filling my asshole to bursting. When he took his cock out of my or Simona's ass, he immediately shoved it into Vera's mouth and his hand replaced it in our ass. After a while, he started to deep thrust his penis into Verce's throat and squirted it down her throat. She coughed all over. Then he continued in our assholes, which opened and contracted in red prolapses when he removed his hand. At times, I (Gabina) may have been out of it. Then it was over. Verča, who was red all over her ass and pussy from the spanking, probably took it the hardest. But I (Gábina) saw that Verča had a few orgasmic twitches too.

At the end, we each had to push PAvla's penis as far into our mouths as possible as a thank you. Because he was already pretty exhausted he fucked all 3 of us hard in the mouth for a very long time. He cum down my throat as a reward for me being the first to take his hand. A little cum leaked out of my mouth. Paul pushed the escaped cum back into my mouth with his penis and I swallowed that too. I don't like swallowing cum. But it was such a relief that I even liked it. I cleaned his penis thoroughly with my tongue and sucked the last drops from the inside of his penis to make him feel good. Then he released us.

At home I (Gabina) fell into bed and immediately fell asleep. The next day I was full of energy and went for a run. I was looking forward to when my butt would stop hurting and I could call Borek and Tom.

Pavel was eventually removed as our trainer because only me and Simona signed up for the next course. They merged us with another group. Now we have a trainer who just giggles and doesn't even correct us. I don't even know if I'm gonna go anymore.
