Panting, Alice turned down down the speed on the treadmill, her average breasts heaving with exertion under the tight confines of her sports bra. Stepping off the exercise machine the lithe Border Collie hermaphrodite bent over to grab a water bottle, taking several long swallows of the cold liquid before upending it over her long black and green-dyed hair, cooling her off a little. Alice gave a look around the deserted gym, her breath slowly returning to her as sweat trickled down her fur, body, making her tight workout clothes cling more to her body, outlining the shape of her areola and the bulge at her crotch. The collie was largely shy about her appearance, this recent bout of exercise mania being a highly successful drive to lose weight and get into shape to remove her personal qualms about her build; as a result, she'd been sticking to the wee small hours in this badly-equipped twenty-four seven gym, this being a typical night there was only one other occupant, a burly shire horse girl, who'd entered without a word to the canine and since sat in the corner lifting a dumbbell repeatedly. All to the better for Alice, as this gave her the chance to take a nice, long, shower without the threat of company or awkward closeness to other patrons.
	
A long sigh of relief left the collie's lips when she walked into the locker room and saw it was thankfully just as empty as when she'd left it, save that the locker next to hers was taken, presumably by the equine still mindlessly building her biceps in the main room. Stripping off her bra and workout shorts, dumping them carelessly on the bench running down the middle of the cramped locker room, Alice took a few moments to open up on her locker and pick up a plastic bad of silver jewellery. Having taken them off to prevent any nasty accidents if she slipped on the treadmill, the canine took a while to carefully replace her piercings, several rings through one ear, a nose stud and finally a pair of barbells threaded through her black-skinned nipples and screwed into place. Alice took a look into the mirror provided in the room to deter any catoptrophobes from daring to attain fitness and nodded in approval as she saw the metal glinting from her sweaty body. They were the only part of her appearance the canine really enjoyed, as they were what she chose. Sure, they hurt a bit to get but they added to her body wonderfully in her opinion, even though she'd never consider showing the ones on her nipples, it was hard enough to muster the nerve to let her see them in a professional manner to get them done.

Fully dressed save for clothes, the herm opened the door to the gym an inch, confirming that the shire girl was still in the middle of her workout, singing softly to whatever was playing on her iPod. Content that she wouldn't be interrupted, Alice stepped into the shower room, turning it on to a nice cold temperature, jumping a little as the torrent hit her, making her furred ball sack shrink towards her body. Soon enough, she was singing to herself as she cleaned off all the icky sweat from her body, soaping up her breasts and testicles, swaying her hips to the rhythm in her head. She was just considering whether or not she dared masturbate quickly in the shower, letting it clean her off from that as well, turning to check the coast was clear when she saw the horse girl sitting in the locker room, staring at her shower. Very clearly, the collie's quick assessment that the huge-breasted and brown-coated blonde who had been building her already expansive muscles that she was female was wrong. The horse was sitting in just a sweat-stained grey hoody, open to expose her massive breasts and was stroking a foot and a half long horsecock. A bright blush crossed Alice's face instantly, turning the fur on her cheeks pink. The canine managed to raise her eyes from the appraisal of the speckled shaft to see that the other hermaphrodite was staring straight at her, making it very clear what the equine was masturbating to.

'Er, thanks, I'll... take it as a compliment?' the collie managed to say, even as her own black cock started to emerge from it's white furred sheath, a glint of silver showing that that was pierced too. 'I'll leave you to it,' she said, starting out of the room.

'Wait,' came a surprisingly light-toned voice, the huge equine standing up to tower over the relatively tall collie. 'Would you like to fuck?' she said, bluntly, blue eyes boring into the smaller herm's green.

'T-thanks for the offer,' Alice stammered in reply, licking her lips nervous, trying to slip out of the shower room past the body builder but instead running into her massive shaft, rigid as an iron bar. 'I'm not sure I can fit that, see.'

'Sure you can,' came the gentle voice from a rather ungentle visage, the equine bending down over the smaller fur, breath hot in her ear. 'Tell you what, I'm a part owner here, you finish up your workout with a special session, I'll give you free full membership, Alice.'

'Wh-How do you know my name!' the collie replied indignantly, staring up at the virtual giantess towering over her.

'Part owner, remember? I saw your membership forms,' the equine chuckled, taking hold of her shaft and rubbing it onto the side of the canine's face, leaving a trail of precum over the white fur there. 'I'll make sure you cum nice and hard and it'll help burn off those pounds a lot faster than using the crappy machines in there,' the horse added, nodding her head towards the main gym.

Biting her lower lip, the collie considered the offer, on the one hand, she could probably pretty easily slip past the horny horse, grab her clothes and be on her way to find a new gym with less horny owners before the horse in front of her could react in time. On the other, it has been a while since the collie had managed to get laid, before she gained the pudge she'd been working so hard on burning off in fact. And the boyfriend who dumped her then certainly didn't have such a tool to please her with.

'Fine,' Alice nodded, earning a grin and another rub in the face with that massive member. 'But,' a finger going up to pause the dominant equine. She ducked out from under the the rod and moved over to the bench, sitting down with a raging erection between her legs, the collie's cock only 8 inches, less than half that of the horse's but decorated with a ladder of piercings running up the underside. 'I'll only fuck you if you tell me your name. I may be about to get cock from a stranger in a locker room, but leave me that pride, got it?'

'Sure,' the grinning equine nodded, moving to straddle the bench, the flared head of her rod seeming to point directly at the collie's face. 'I'm Sasha, you know, the name over the door?' Sasha chuckled in her strangely high voice, picking up one of the soaking collie's legs an holding it the air, squashing a breast against it while her other hand lowered her shaft to push the oversized flare of her shaft against Alice's tight pucker.

'W-wait, what? No-one said anything about anal,' the collie protested, trying to close her legs against the vice-like grip on her ankle keeping her spread.

'Well, I forgot to pack a condom and I'm not about to have kids with some slut in a locker room, am I?' came Sasha's quick reply, shoving her hips hard forwards and spearing her rod deep into the canine's tailhole, spreading the entrance wide and cruelly, causing the collie to howl in a mix of pain and surprise. 'Oh, shush you virgin whore,' the horse growled, her cock twitching with each heartbeat inside the tight confines of the dog's rectum. 'It'll feel good, soon, I promise.'

'A-ah, you're such a bitch,' the collie gasped, her cock swinging in the open air as the massive herm topping her started shifting her hips back and forth, making the collie stifle a moan at the feeling of being so filled. 

'And you're such a slut,' came the quick reply, the horse starting to speed up her thrusts into the stretched hole, making the collie writhe on the hard bench. Each thrust went deeper and deeper into the comparatively tiny hermaphrodite, causing her belly to start to bulge with the shape of the rod drilling deep into her.

The pair fell into a silence save for grunts and moans as both concentrated on the feelings of the far from gentle anal sex. The collie's arsehole soon started squelching with precum generated by the relentlessly pounding cock inside her. The canine's own shaft was slick with fluid, showing that despite her protests the squirming collie was enjoying the rough treatment under the dominant equine, her studded tongue hanging out of her mouth as she moved in time with the thrusts, breasts swaying and spraying droplets of water with each movement Sasha made.

Without a desire or a need to hold back, the horse's testicles soon start churning with the need to spread her speed and Sasha doesn't even attempt to hold back. Soon enough, the horse is whickering at the top of her lungs and the dog is barking under her as the body builder's cockhead flares, starting to shoot cum deep within Alice. The canine's belly started to swell, causing her to howl at the sensation, her knotted shaft starting to squirt a pitiable amount of sperm over her breasts and face in contrast to the pints filling her belly. Sasha let's the collie's cargo sit there inside her for a moments before she gains her strength back, the horse's powerful legs wobbling a little in the aftermath of her orgasm. Pulling out quickly had to move back to avoid of gush of thick white seed from the panting canine's gaping arsehole.

'Have fun, slut?' the horse asked, panting but showing nothing like the exertion plastered over Alice's sweaty face, the collie lying in a growing puddle of water of cum.

'You're a bitch... you know you could have... fucked me... earlier... need another shower now...' the collie complains with heaving lungs, sitting up slowly and wincing as she feels her sore hole try and close against the constant stream of seed leaking from inside her depths.

'You might,' Sasha laughed walking around to the front of the seated canine, her still erect cock poking the collie's face and smearing seed over her fur. 'Clean me off, slut.'

'Why,' panted Alice, looking up into the equine's blue eyes far above her. 'I'm tired and you already fucked me,' she pointed out, prodding at the wet member in her face.

'Well, I know where the water shut-off is, have the key for it and you've got a face covered in cum, missy,' the high-pitched voice said plainly and was soon rewarded with a look that should have left the equine a smoking crater on the floor and a studded tongue stroking her cock.

Alice worked quickly, holding the shaft still with one hand and running her tongue up and down the sticky length, tickling with her tongue stud a little, making sure to coat every inch of it with her saliva, the collie reflecting that maybe she didn't really mind the taste of the horse's seed. Soon enough she'd cleaned every inch of the huge horse-cock, leaving the owner of it panting and twitching above her. The smaller hermaphrodite was about to pull back and get into the shower to reflect on her sore hole and try to clean it of seed so she didn't leak into her panties when Sasha suddenly clapped a hand on her head, the other stroking her length just as fast as the first time the two made eye contact. With a groan, the horse let go of her restraints again, stamping a hoof on the tile floor as her flared again shot an astonishing amount of sperm. The flinching Alice was soon coated almost completely with white goo, her eyes forced close with it and coughing up that which landed in her mouth.

'You were fun,' came a voice from somewhere in the whiteness that was what the collie's world had temporarily become, echoing through the seed that had landed in her air. 'I'll leave you my number,' Sasha continued, smacking a square of cardboard into the cum on Alice's face, her hooves sounding on the tile as she started to leave, opening the door and raising her voice to call back. 'Call me if you want a private session. You keep coming to them and maybe I'll do your cunt!'

Later, with Alice almost completely cum free and walking on unsteady legs back into the locker room, bending down to pick up the stained business card that had been left with her. Well, she thought, it was pretty fun, in it's way and Sasha was pretty hot despite her kinks and maybe she'd listen to her more next time. Her mind mostly made up the call the number after a while, the collie, paused, staring at the spot where she's left her exercise clothes.

'That slut stole my shorts,' she growled, angrily.
