Diesel the Dobie drops by the gym late at night hoping to have no one about, but when his workout is interrupted by a lovely Bou lady he gets more of a work out then he planned.


Walking up to the glass door and taking a quick peek inside, the entire building was empty from what they could see, despite it being a Friday. That was a relief. Having to deal with other people here was a fear that the Doberman had held since they signed up. It wasn’t like them to decide to join and go to a gym, but lately they’d started to feel a bit self-conscious about how they looked.

Being a 24-hour gym, the dobie had to beep their ID card against the scanner to get in. Tapping their card against it, they then quickly slipped through and into the place they’d been dreading going to since they’d signed up. Glancing around Diesel could see there were all sorts of different machines and weights and things they didn’t even know how to use.

That was why they had decided to come at half past eleven at night. They were certain that no one would be there, and they could learn to use the machines and work out without feeling judged by anyone. From what they could see, it looked like their plan had worked.

Smiling as they made their way around some of the equipment, they headed over to a group of benches against the back wall. Putting their bag on the bench, they removed their hoody they had worn. It was a little cold outside currently, but for the most part it was nice.

Deciding to start with something they figured wouldn’t be too hard to get the hang of, they headed over to the treadmills. Looking at the little display, the canine could see how to start it up and set the speed. Taking a few more moments to adjust it and work out a decent starting pace, Diesel finally felt like they were ready.

Pulling their ear buds out of their pocket, they slipped them into their ears before picking up their phone and hitting play. They’d already been listening to a group of songs they felt made them motivated, so figured it would be a good playlist to continue whilst they exercised.

Climbing up onto the treadmill, which they’d only set to a quick walk speed, they had begun to feel more comfortable. Their music in their ears and no one around to judge him. Just them there, working out so that they would no longer feel like this unfit and ugly person.

After a few minutes at the pace they chose, the dobie decided to increase the speed a little, feeling like it wouldn’t be too much more effort. Now at a jogging pace they felt like it was perfect for them. Turning their music up to the max volume, they truly were at peace and in a way kind of enjoying themselves.

Softly singing along to their music, the canine looked at the display on the treadmill, curious as to how long it had been. Pressing the button to flick the display to work out length, it popped up with a little under fifteen minutes. It hadn’t felt like it had been that long, but they guessed that they’d just lost themselves in their music and time had flown by.

Letting it tick over the fifteen-minute mark they hopped off the treadmill and turned it off. They were feeling a bit out of breath now that they’d stopped, and their legs were hurting. Perhaps they should have taken the advice they’d read online and done some stretching before they started. Ah well, lesson learned for next time. For now, they were going to take a moment to sit and catch their breath before trying something else.

Turning to head over to their bag they’d left on the benches, they suddenly realized there was someone else there. Sitting over by their stuff was a caribou who was watching them. Looking at them as he walked over cautiously, Diesel could see that they had an admittedly impressive rack of antlers on their head. She also had another impressive rack upon her chest, something he took a moment to admire.

As he got nearer, he could see she must be a regular here because she had quite decent muscles on her. She had looked away from him and was on her phone now, so he headed towards his gear thinking that he might just go. Better that way than making a fool of himself anymore, especially after she had probably been listening to him sing and thinking how weird he was.

Reaching his stuff he quickly started to shove his hoody into the small bag he had brought with him. As he did, he was interrupted by a water bottle landing in front of him. Looking at it weirdly for a moment, he suddenly started to feel stupid again. Straightening up and popping his earbuds out of his ears, he looked at where it had come from and found the bou smiling at him.

“You were sounding a little husky at the end there. And I didn’t see you have a drink at all, so I thought you could do with some.” The cervine spoke smiling at him.

“Uhh thanks?” he responded picking up the water bottle. She was right though, his throat was a bit dry, and he hadn’t brought any water or anything with him.

“First time coming in? Few people are willing to venture out this late just for a work-out.”

Having just chugged half the water bottle, Diesel realized that he had been gulping it down, he took a moment to catch his breath again before he answered her.

“Yeah, I had kind of hoped that no one would be here” He nervously said as he sat down beside his stuff on the bench before continuing. “Also, I’m a Doberman, not a husky.”

His somewhat silly joke managed to extract a laugh out of them both and he felt a lot more relaxed as though he’d managed to break the ice and free himself from his nervousness. The bigger caribou sitting beside him still intimidated him a little, but it seemed like she was friendly enough.

“Not many people come to the gym this late at night, except of course people like yourself who are hoping to have the place to themselves and people who work night shift.”

“So, which are you then?” the canine asked the caribou inquisitively.

“Neither actually. I missed coming in this morning, overslept for work, so I figured I’d pop in tonight and do a little.” She emphasized her point by raising her right arm and flexing her muscles for him to see. “But given how inexperienced and unprepared you seem, let me hang about for a bit and I’ll give you a hand.”

Hopping up off the bench with an enthusiastic bounce, as if to prove her point, she started over towards the dumbbells. Watching her walk over Diesel took more of a look at her. She was at least a head taller than him and was wearing quite a tight-fitting crop top and a pair of gym shorts. Almost what you would expect a typical gym girl to wear.

“Are you going to sit there and stare or do you want to actually do some exercise?” The cervine called out from where she had stopped.

Feeling guilty about staring, the dobie made his way over as she began to grab some of the dumbbells. Handing him a pair of the smaller ones, she picked up one for herself before she began to show him the correct way to lift them. Warning him that if done incorrectly you could seriously hurt yourself.

After she showed him how to do it, she placed the one she’d grabbed for herself back on the rack where they came from. It seemed that she wasn’t going to work out as well, which kind of struck Diesel as odd. He waited a moment to see if she was going to pick up another, maybe bigger one, but when she didn’t his curiosity got the better of him.

“How come you’re not doing it as well? I thought you said you missed this morning?” He curiously asked.

“Oh, I already did.” She smirked at him “I was in here before you came in.”

“Don’t let me keep you here then!” Diesel quickly said, still feeling embarrassed at having someone here whilst he was learning how to do things.

“I’m good, I don’t mind helping out people who haven’t done this kind of thing before.” she said with an almost devious grin. “Go ahead, show me what you can do!”

Still nervous and shy, Diesel began to lift the dumbbells the way she had told him was best. He found the ones she picked to be quite easy to begin with, but after a few lifts he was starting to struggle a little. Not enough to stop but enough that it felt like he was putting in a bit of effort.

Now that he had started to work out, the caribou who was helping him had sat down on a nearby machine and was fiddling on her phone. The Dobie wondered why she had decided to help him out, not that he minded, but he didn’t think he needed help.

Finding himself looking at her again, Diesel could see her well defined figure a bit better. She had muscles that would make most people envious, but to match her muscle she also had lovely feminine looks, a voluptuous set of tits on her and a firm looking ass from what he’d seen from behind.

His arms had started to hurt from lifting the weights by the time he’d caught onto himself checking out his mysterious helper. Deciding now was probably the time to stop, the Doberman returned the dumbbells to their rack. He’d made sure to put them back where the caribou had grabbed them, as his new friend had told him it’s common gym courtesy to put things back in their rightful place.

“Oh, done already?” The caribou asked him as she saw him placing the weights back.

“My arms feel like they’re burning, really tense and sore” he answered her back.

“You didn’t stretch before you started tonight, did you?” She frowned whilst questioning him.

Looking away sheepishly Diesel knew that he was supposed to but didn’t think that it mattered that much. Maybe he did need a bit more help than he knew, but he would have figured that out anyway, right?

“N-no, I didn’t stretch at all” the Doberman softly replied.

The caribou let out a loud sigh before softly laughing at him. “It’s alright, most people new to the gym don’t understand how important stretching is.”

Getting up from where she was sitting, the bou got up and walked towards him. As she did Diesel could see that she was looking him over. It made him nervous, but he guessed it was that she was trying to figure out if he was worth helping or if she should quit trying.

“Go grab another drink of water, I’ll help you out with one more thing than I think you’ll have had enough for one night” The cervine told him.

Wandering over to the bench where he’d left the bottle, he wondered why he was letting this caribou, whose name he didn’t even know yet, tell him what to do. Looking back at her, she was over by the bench press, adding weight to it for him.

Sipping on his water slowly in the hopes that it would give his arms some time to recover, the Doberman felt that, despite being told what to do and feeling embarrassed, tonight had been good. Maybe he would come back again another day.

Seeing the cervine was waiting for him now, he quickly put the lid on the water bottle and tossed it back. Jogging over towards the bench press the caribou was now waiting by, the dobie suddenly felt nervous about how much weight she’d added.

“You sure that I can lift that much?” he nervously asked her.

“Yeah, no sweat! You’ll be fine! Plus, you got me here if you can’t” she boasted as she raised her arms again showing off her muscles to prove herself.

“Alright if you say so...? Miss?” Diesel said probing a little for her name.

“OH! Shit, here I am telling you what to do and I aint even told you my name!” She realized with a hearty laugh. “My name is Cera” the caribou said with a smile. “I’m uh, sorry I guess, for not telling you before.”

“I’m Diesel” the Doberman told her, again feeling embarrassed by his stupid name.

“Diesel?” Cera said with a smile and soft laugh. “That’s such a cute name! It suits a guy like you!”

The caribou’s comment about his name had caught him off guard. Normally when people hear his name, they make fun of him for it. Saying it’s a name for a feral or four legger pet. As much as he hated the crap that came with his name, he’d kept it. After all it was one thing he still had from his trucker dad who’d been killed in an accident when he was young.

“T-thanks?” Diesel said nervously. Still unsure about her comments “It’s weird to hear someone like it. Normally most people think that it’s stupid.”

“Fuck off” Cera said suddenly. “It’s a cute name and I think it’s good.” She said with authority “But get that wagging butt over here, you’re not done yet.”

It was only when the cervine had made her remark that the Doberman realized he’d started to subconsciously wag his tail in response to the compliments and nice things she’d told him.

Sitting on the bench press, the Doberman properly looked at the weights that Cera had put on the bar, it was only about thirty kilograms, nothing too much. Even if it had of been a lot more the canine was feeling invigorated and like he could take on the world at that moment.

Lying back on the machine, the Doberman quickly lifted the bar off the bench press. Having not taken time to ensure he was in the right position to lift it, Diesel quickly found that he had a poor grip and hold on it. Before he could get it back on the machine, he lost his grip on the bar, and it fell on him.

The bar dropped onto his chest knocking the wind out of him. Almost as quickly as it had fallen, it had been lifted again. Gasping for air, the canine lay there taking in heaving, deep breaths, until he felt like he was able to breathe again.

“Are you alright?” Cera’s voice cut through his temporary daze. Glancing up at her he realized that she was standing over the top of him on the bench. She must have seen the bar drop and rushed over him to get it off as quickly as possible.

Giving the bou a nod the Doberman let Cera know that aside from clearly having the breath knocked out of him, he was okay. He was pretty sure he was anyway. His chest hurt, but he was glad that she’d managed to save his ass before he had injured himself seriously.

“Good, I’m glad you’re okay” Cera said before looking at him sternly. “If you’re going to lift any weight you need to make sure you’re in the correct position!” the cervine scolded him whilst physically moving his body, to what he only could assume was a better position for him to lift the weight “You also need to ensure you have a spotter, someone ready to help lift the weight back up should you struggle, or like you just did, drop the damn thing!”

“Now try again, and don’t go trying to kill yourself this time!” She firmly said making the canine feel intimidated all over again.

“C-could you possibly” Diesel nervously asked, “Possibly not stand directly over me?”

Cera didn’t move. She folded her arms across her chest looking down at him. Diesel didn’t know how to take the look she was giving him. She had an almost dominant, I dare you to try, kind of stare. Diesel contemplated a response to her defiant look, but before he could the larger caribou dropped herself slightly roughly onto his lap.

“I think I’m going to stay right here and make sure that you don’t hurt yourself again.” She spoke in an almost teasing manner “Now be a good boy and let’s see you lift that weight there.”

The Doberman was caught out by how she was talking to him, and why the hell had it made him feel good again. Diesel could feel his stupid tail wagging as well. He wasn’t going to let her make a fool of him though, he was going to lift this weight like she’d told him to, then he was going to get his stuff and leave.

Grabbing a hold of the bar again, Diesel made sure he had a good grip on it, before carefully lifting it free. Surprisingly, given what happened last time, he found it wasn’t too bad. Slowly lowering it down to his chest and then lifting it back up was a heck of a lot easier than he had thought.

On his third time lifting it, his mind started to get distracted. Every time he lifted it up, his hips would move up pressing his crotch against the caribou’s. Through the thin pants and shorts they were wearing he could feel the warmth from her nethers on his and it was making it hard for him to concentrate.

He didn’t know how many times she wanted him to lift it, but it was getting harder to with every repetition. Not just because of the exertion but because his blood was starting to flow to another part of his body. There was absolutely no way that she couldn’t feel his tip poking out of his sheath now.

After his seventh lift Diesel couldn’t take it anymore and put the weight back onto the machine. He needed to get her off, or he was going to sprout a boner here in the middle of the damn gym. Despite him placing the weight back on the machine, the caribou hadn’t moved.

Looking up at Cera, Diesel found her looking at him quite angrily. Had she wanted him to continue? Did he do something wrong? It didn’t matter he wanted to have her off him.

“Did I say stop?” Cera suddenly said to him. “I didn’t tell you to stop, you were doing good.”

“I’m sorry but I can’t concentrate with you there on my... my” He cut himself off too embarrassed to say more.

“With me what? On your lap? With your dick rubbing against me? Don’t think I can’t feel it.” Cera smugly told him. “If you want to get fit then you need to look past distractions. You can’t let something like a girl on your lap distract you.”

Before Diesel could say anything more, Cera stood up off him and quickly pulled his pants down. Letting out a quick cry of shock, the Doberman reached down to try and pull his pants back up. The bou grabbed his arms and pulled them away before he could though.

“Hey what do you think you’re doi-.” “Shut up!” Cera abruptly interrupted him. “You are going to be a good boy for me, and you are going to do as I ask. Do you understand?”

Whap, thwap, whap. Fuck. His tail was wagging again. There was no way he could deny the fact that he was liking her calling him a fucking good boy. He’d never had anyone do that before, not any of his former girlfriends nor his parents, no one. He had no idea that it would make him feel or react like he was now.

“Seems like you like being called a good boy” Cera softly said in a sultry tone as she leant down over him, her head coming closer to his groin as she did. Following it down, Diesel was shocked to see his own cock was proudly protruding from his sheathe. He’d been too focused on what the cervine had been doing to realize what his own body was up to.

This was wrong, they shouldn’t be like this in public, she shouldn’t be telling him what to do. She shouldn’t be allowed to control him, yet the Doberman didn’t want to stop. Despite the confusion in his brain, he wanted to continue, to have this beautiful bou lady call him a good boy.

Diesel’s thoughts were interrupted by Cera’s tongue running up the underside of his dick. The feeling of it caressing his cock as she ran it from base to tip made the Doberman shiver in pleasure. The bou then gently wrapped her hand around the base of his cock before she swirled her tongue across the tip.

Looking directly up into his eyes she lowered her mouth onto his cock, slowly sinking deeper, allowing him to feel the warmth of her muzzle embracing his dick. It felt so good to him. Fuck, Cera was hitting all the right pleasure buttons for him, and he was loving it.

She had taken nearly all his dick that had emerged from his sheathe into her mouth, and yet she hadn’t broken eye contact. As her nose bumped into him, her tongue slid along the underside of his member and into his sheath. Like it was trying to coax more to come out of him.

Letting out a soft moan at the pleasure he was feeling, Diesel could still hardly believe they were doing this here. The caribou was now bobbing away on his pole, she’d closed her eyes, though it was clear she was enjoying this as much as he was.

Cera had started to pick up her pace, she was sucking his cock in a way he’d never felt before, and he was loving every second of it. However, that also meant that he was already struggling to not cum. The bou was taking his entire length from tip to knot in her mouth, whist stopping knot deep at times to run her tongue across the growing bulb.

Fuck, he couldn’t hold out any longer! The Doberman was so close to exploding his cum down his caribou cocksucker’s throat. Diesel grabbed her antlers and pulled her head down to his knot and started thrusting up into her mouth. Cera was struggling, trying to pull away, but the canine had found a strength he didn’t know he possessed to hold her there.

Cera’s eyes flew open as the Doberman’s dick erupted in her maw. He was holding it as deep as he could, his knot pressed to her muzzle. Making her nose fill with the scent of his cock, and as much as she loved that smell, she was in control here! Once he was done, she was going to make him regret forcing her to swallow his load, not that she wasn’t going to originally.

Letting out a soft whimper as he released his load, Diesel was too lost in bliss to see the furious look he was receiving from Cera. He was still holding her knot deep, but his strength was waning. His tail wagging beneath him, his mind was currently twisted and thinking of how good of a boy he had been, giving the lovely lady his load to satisfy her hunger.

No sooner had he let go of her antlers; the caribou’s head flew up from his crotch and was furiously lingering in front of his. Diesel had his eyes closed, still lost in the moment, but he opened just as quickly as Cera’s had before when she started talking to him.

“You. Were. A. Naughty Boy!” Cera spat out, still taking deep breaths after being held on the canine’s member.

“Wh-What?” Diesel sputtered in response to her. “I-I came for you, I gave you what you wanted r-right?”

“What I wanted” The cervine spoke provocatively. “Was you to be a good boy. And good boys don’t cum until they’re told.” She continued as she stepped to the side of the machine.

Diesel went to sit up and try to talk to her, as soon as he did though he found her hand wrapped around his muzzle and pushing him back down on the machine. He didn’t know how to respond to her sudden show of physical dominance, so the Doberman decided that it couldn’t hurt to obey her. After all she just wanted him to be a good boy and hurting him wouldn’t get that.

Cera stripped off the shorts she had been wearing along with her clearly damp underwear. She had really been enjoying sucking on the pup’s cock but what she had been hoping for was a nice fuck. Hopefully his tongue was as good as his cock had been though, because seeing how he had decided to blow in her muzzle, she was going to make him use it instead.

Stepping back over the prone canine, she leaned against the barbell that still rested on the bench press and lowered her slit towards him. Diesel had just watched her strip off and climb back over him, but from the moment she’d dropped her underwear his nose had been flooded by the scent of her arousal. Similarly, his eyes had been drawn to her soaked pussy.

She was extremely aroused, and it had been from him. As she lowered her cunt towards his mouth, he had instinctively lifted his head and ran his tongue across her folds. The caribou tasted divine to him.

Diving in, he slid his tongue right into her. Cera for her part, lowered herself to the point where her weight was keeping his muzzle pinned against her without squashing him. The Dobermans tongue was darting around inside her, flicking this way and that, leaving no part of her that he could reach untouched. Even those he couldn’t he was trying to get too.

Slipping his tongue back out, he ran it across and then swirled it around on the Bou’s clit. Letting a moan escape her lips, Cera found the Doberman to be good at what he was doing. He’d managed to hit her in all the right places so far.

Looking up at her as best as he could, Diesel brought his hands up, pressing them against her firm yet plush ass cheeks. Using all the strength he could, he pushed her harder against his muzzle, he wanted more of her, more of her delightful taste. Slipping his tongue back into her, he went back to tasting the depths of her delicious pussy.

“Oh fuck” Cera gasped out as Diesel hit a sensitive spot inside her.

Taking cue from that, the canine continued to flick back to that spot. Soon he was finding other places that made her gasp softly or made her pussy twitch in response to his ministrations. The caribou on top too knew he was starting to catch on to her tells and was loving every moment of it.

Grabbing a hold of the canine’s head and pressing it hard against her pussy, Cera’s hips were twitching as she began her climax. Diesel didn’t let up his tongue fucking as she did, he was determined to give her as much pleasure as he could. He wanted to please her and have her call him a good boy again.

The thought of her calling him a good boy again, along with him being happy to have given her the pleasure he believed she wanted, had his tail wagging like a puppy receiving a treat. Throughout the entirety of her orgasm, he continued to keep his tongue lashing about inside of her.

Cera felt like she was in heaven with how hard she had managed to cum from the dobie’s tongue. Apparently, the canine had a talent for eating girls out and although she had already orgasmed, he was still going to town on her nethers. Despite her still twitching cunt, she had to get him to stop.

“That’s a good boy, you can stop now” Cera said as she gently pushed his head away from her cunt.

Leaning on the bar and lifting her hips up away from the Doberman’s muzzle, Cera took a moment to catch her breath and focus again. Even though she had told him to stop he was still gently licking her folds occasionally. His soft licks were keeping her horny and she wanted more.

Looking back behind her, she wasn’t too surprised to find the canine’s pole to be standing erect. Diesel having noticed her look over her shoulder presumably at his dick made a soft whining noise. Letting her know he was horny and wanted more from her too.

Not even giving a second thought to it, Cera moved back along the bench press until her mound sat above Diesel’s cock. She took a moment to admire the pleading look he was giving her, before she dropped herself right down onto his dick. Impaling herself to the knot, the bou let out a soft moan. His dick felt bigger now it was inside of her cunt and not her mouth.

“Good boy” Cera softly breathed, “Time for the final part of your workout”

As she spoke the Caribou felt Diesel’s dick twitch inside of her, it seemed being called a good boy really did get to him. It made her wonder just how much she could possibly tease the poor boy with it. That was for another time though, right now she had his cock buried deep into her and she wanted more of it.

Resting her hands on his chest she lifted her hips, sliding herself up on his pole, stopping to keep the tip still in her. Slipping back down, she buried it back inside her soaked pussy. The dobie’s dick inside her was rock hard, and every time her slit bounced off his knot, his hips would twitch upward.

Looking down at Diesel, Cera could see that the Doberman was watching her bounce on his cock. Looking at him with a coy smirk, the bou leant down over the top of the canine. Given her height advantage to him, she was able to still ride his dick and have her breasts resting upon his shoulders. She leant her mouth in close to his ear, giving it a gentle nibble before she whispered into it.

“You’re being such a good boy, letting me ride your fat cock” She muttered into his ear, slamming her hips down harder to emphasize her point. “A very good boy who used his tongue wonderfully, and now is letting his bou mount him, you’re not cumming this time. You’re being a good boy, and you’re going to wait.”

Cera could feel the effect her words were having on the poor dobie boy. His eyes looked unfocussed and glazed over like he was lost in pleasure. His tongue had drooped out the side of his mouth cutely and he was panting from the exertion he was being put through. Well, was putting in. Whilst she had been looking at the effects her words had on the canine, his hips had started to thrust up, meeting hers with a hard slap.

His hands were now resting on her butt and pulling her down harder with each collision of their hips. To Cera this was heavenly, she was loving every moment of this hard fuck. The way the Dobermans dick was hitting all the sensitive spots inside her with every thrust, the way she could make him squirm and react to her calling him a good boy. Fuck, she didn’t want this to end.

She quickly was drawn back to the increasingly harder thrusts the canine was committing to, as well as how hard she was slamming her hips down on him, when she felt her pussy roughly split open and allow his mostly swollen knot to lock itself inside of her. She hadn’t been ready for it and hadn’t wanted it yet. She wasn’t ready for this to end yet!

Sitting upright in his lap again, she grabbed his hips, trying to pull his knot back out so she could keep going for longer. Pushing him down roughly and lifting herself up wasn’t working, he was too big already. His dick was starting to twitch inside of her, she didn’t want to hurt the poor guy, but she wanted more.

Grabbing the Doberman by the throat, the bou pulled his head up until his face was pressed against hers and they were staring directly into each other’s eyes. He looked more focused and less out of it now, which Cera hoped meant that Diesel would hear what she was about to demand of him.

“You will not cum! You are going to be a good boy and let me cum first! If you don’t then you will be a bad boy and I will punish you!” She growled at him in a feral tone.

Diesels ears went flat against his skull as the words registered in his head. He wasn’t allowed to cum, he was going to be a good boy, he had to be! But he was so close already, and she had let him bury his knot in her. The Doberman let out a loud whine, begging her to let him cum, but the caribou didn’t respond.

Cera was standing above the bench press with the canine hanging from her tight cunt by his still swelling knot. Damned if that silly boy was going to get to cum before she had gotten off again! Grabbing him by the hips, the caribou started to use him like a living dildo. Pulling his hips up and down against hers, getting as much movement and pleasure as she could from her current situation.

The awkward position and almost painful way she was smashing her hips against his, made it easier for Diesel to hold out from cumming. But he wouldn’t be able to hold out for long. His balls felt like they were swollen to double their normal size from how much he had enjoyed the dominance of the larger girl.

Holding his hips flush on hers, Cera ground herself against him, she was getting close to cumming. His dick throbbed inside of her, and his knot was fully swollen and locked. The poor dobie was set to burst at any moment, and he had done well to not cum yet.

Her legs came out from under her, and she dropped back down onto the bench press with the canine. As they landed their hips slammed roughly against each other’s, Diesel’s cock rammed deeper into her then it had been, and that jolt was enough to finally kick off her orgasm. Cera’s pussy gripped and squeezed around his cock as her hips twitched and ground against him.

Despite being overwhelmed by pleasure, Cera didn’t want Diesel to be denied the pleasure she was experiencing. Gasping and moaning throughout, she gave him the command he had been waiting for.

“D-diesel! F-fuuck!! Cum for me! Be a good boy and FUCKING CUM!” The last few words she almost roared out at him.

That was all he needed to hear and with a howl that echoed through the gym, his dick exploded his hot, voluminous load deep into her spasming tunnel. His hands held onto her, and he pressed his hips up into her ensuring that he came as deep as he possibly could within her. Grabbing his muzzle Cera passionately kissed the Doberman, tongues entwining as they both lost themselves to their orgasms.

Several minutes passed before they broke off the kiss. Cera could still feel Diesel’s dick trapped inside her twitching away. Sitting up in his lap, Cera let out a soft moan at the feeling of his dick adjusting to the movement. Running her hand up under his now sweat soaked shirt, she caressed his chest.

“You were such a good boy” Cera teased eliciting a slightly harder twitch of the Dobermans dick inside of her along with the obvious signs that his tail was wagging again.

“Fuuck, stop please” Diesel begged of her “My hips are sore, and I think you’ve completely drained my balls.”

Reaching around behind herself and giving his balls a gentle squeeze, she found the dobie’s balls felt a little smaller now. Her fondling made the canine twitch in response due to how sensitive he was from just having such an intense orgasm.

“Seems like we’re going to be stuck here for a bit” Cera quipped “What do you think, could you do a couple more reps of that weight?”

Diesel didn’t immediately reply to her, instead he let out an amused laugh, she surely couldn’t be serious. They’d just had an intense fuck, and she wanted to know if he could lift the weight again. There was no way he could.

“I’m going to be honest here” Diesel said as he leaned up onto his elbows “I haven’t had sex in a couple of months, and I have never ever had it quite as intense as that. I feel like I’ve done three times the work out you initially suggested.”

Cera found it quite amusing that she had been his first fuck in a while, but it had also been quite the thrilling time for her as well. She enjoyed rougher sex and hadn’t initially intended to be so with him, but she had gotten lost in the moment. Not that he had seemed to complain. It seemed like he had almost been entranced by her calling him a good boy.

“So… how long do you normally last?” Cera asked slightly awkwardly as she’d never actually done anything with anyone who had a knot, so she was inexperienced in this.

“Oh, Uhh, well... N-No one’s ever let me knot them before” Diesel said sheepishly. “But usually once I’m done and out my knots usually down in about ten to fifteen minutes. N-no offence here, but you’re a larger person so it might not have to wait as long.”

Letting out a soft chuckle at Diesel being gentle with her, despite the roughness of their prior conduct, she knew he was probably right. Easing herself up off him, she found him lifted with her for a moment before his knot slipped free of her. It hurt a little as the widest part slid through and she instinctively reached down to feel if she was okay.

Everything felt normal down there, aside from the obvious cum that was leaking a little out of her pussy. Lifting her hand up she looked at the cum that was on her fingers, Diesel gave her a little chuckle knowing that he’d cum in her and they’d not used any kind of protection. Curiosity hit the caribou and she decided to lick the cum off her fingers to see what he tasted like. She found that he tasted okay, not great but also not too bad.

Curiosity now sated she picked up her shorts off the floor before heading back over to where their gear had been left on the benches. Pulling his pants up as best as he could with his still semi-erect dick flopping about. Diesel tucked it into his pants before making his way over to the benches as well. He was sore and exhausted from his workout and was ready to head home.

“Those pants don’t leave nothing to the imagination, do they?” Cera lightheartedly poked at him as she pointed towards the very obvious bulge in his pants.

“No thanks to you, they don’t no.” Diesel retorted back. “But at least I put mine back on” He remarked, coming up behind her and giving a gentle slap on her still exposed butt.

Having another soft laugh at the dobie, Cera stuck her damp underwear in her bag before putting the shorts back on. She collected her stuff and was ready to head off home herself. Standing up and heading towards the door, Diesel was not far behind her when she reached it.

“Hey Diesel” The caribou said whirling around to face him again “My roommates and I are planning to have a few drinks tonight seeing as we all have the weekend off. Wanna come?”

Diesel froze for a moment; completely caught out by the request she’d just casually tossed his way. He couldn’t remember the last time he’d had a few drinks and had some fun, but it was also with people who he didn’t know.

“Fuck it, why not!” Diesel said as he made his way to where the caribou had stopped by the exit.

Opening the door, Cera had to duck and wiggle sideways through, it clearly hadn’t been designed for tall people, or people with large antlers or horns. The Doberman slipped out whilst she held the door for him, before following her over to her car.

“So, sure you want to come with me? You don’t have to at all. You can head home, and we can both forget what happened here tonight, or remember it as a good one off.” Cera double checked with Diesel one last time to see if he really wanted to come back with her.

“Yeah, I honestly have nothing better to do, and it would be better than going back to my place alone” The dobie reassured the bigger gal that he was comfortable with going to her place.

“atta good boy” Cera teased at him again with a cheeky grin. The new friends headed off to her place to enjoy whatever the night brought.
