Erica was in her clinic, on the table was a large German Shepherd dog who’s owner wanted to use for puppy breeding purposes and wanted a clean bill of health.
“Well Kate” she said smoothing down her crisp white uniform, “Ranger here seems to be in good shape, but we should give him our final test before we sign off on his health report.
“Good!” said her Veterinary assistant Kate, “I’m horny as fuck”
Erica smiled, the 30-year-old had been a veterinarian for half a dozen years now and Kate had been her assistant for the last two, it had been a thrill to find someone else who shared her love of animals. Plus the fact that the bubbly 21-year-old was petite, blonde and had 36C breasts tipped with strawberry red nipples was a real bonus. Erica herself, who was tall, slim, dark haired and had small perky tits with large dark brown nipples, could not have been more different.
The two women lifted the dog down from the table onto the tiled floor, Kate took off her blue lab coat, underneath she wore only stockings and suspenders, her large breasts were plump, Erica loved them.
“OK Ranger” Erica said, the dogs ears pricked up at the sound of his name, “Let’s see how good you’ll be at breeding” Erica squatted down next to the animal and reached beneath his hips. Grasping his cock firmly in her right hand she began to jerk him hard, he immediately reacted and his cock emerged from its sheath.
“Good signs so far” Erica said in a business-like tone, her left hand strayed between her own legs finding her rapidly moistening pussy. “You should get ready Kate” she added.
The small blonde applied lube to her pussy and slid in two fingers, “Oh! Yes!” she smiled, “I ready now!”
With that she got on her hands and knees on a small absorbent mat, Erica brought Ranger forwards and encouraged him to mount her, the dog did not need much encouragement. “I’ll make sure he doesn’t knot you” the Vet said, “We don’t want you stuck down there for half an hour”
“Don’t mind if I am” Kate quipped cheekily wriggling her cute butt, Erica shook her head, her assistant never said no to anything and seemed to be constantly horny, but Erica didn’t mind that, fucking the patients was one of the perks of this demanding job.
“Oh! Come on boy! Fuck me!” Kate moaned as the dogs cock was fed into her waiting cunt by Erica, the large dog eagerly pumped his big, hard dick into her, Erica knelt beside them watching and masturbating her own hot pussy as the dog went to town on her assistant.
“Fuck me Ranger!” Kate was often loud during sex but, that wasn’t a problem, the clinic was sound proofed so she could be as loud as she wanted. “Yes! Yes! Gimme that big dog dick!” she grunted as Ranger pounded her pussy, Erica occasionally pulled the animal back a little to avoid knotting before going back to concentrate on her own orgasm.
She rubbed her clit hard and pulled her big nips, “Mmmm, yeah!” she sighed, “I love watching you get fucked by a big dog”
“And I love being fucked by one” Kate replied as Ranger filled her pussy with spunk, “Oh fuck I’m gonna cum!” she groaned, “Yes, cumming!”
Kate’s squirt mixed with dog sperm squirted out of her pussy and Erica climaxed as she watched, “Fuck yes!” she whispered, again very differently from her excitable assistant.
Erica returned the dog to it’s owner in the waiting room along with a clean bill of health while Kate dressed and cleaned up, the rest of the morning was taken up treating pet rabbit’s, hamsters and a cat. So no fun to be had there.
After lunch the two women got into Erica’s car and headed into the country, they had received a call from an eccentric old spinster who had a cottage with a large paddock where she kept a few goats and a donkey, called Pedro, it was Pedro who she was concerned about.
“He’s just not himself” the old lady said unhelpfully as she showed them to the small stable where the donkey was, Kate giggled quietly, then gasped as she saw Pedro, the Donkey had a huge hard on and was breathing heavily, “and I don’t know what is wrong with him” the lady went on.
“Hmm” Erica began, looking concerned, “I think I know what the problem might be” she nodded, “Oh!” the old lady looked concerned, “I hope it’s not serious” she said.
“No, no” Erica replied in a soothing tone, “It’s just something that happens from time to time, I’m glad you called us” she added, Kate nodded enthusiastically with a big smile on her face. “Just leave us to it and Pedro will be back to normal in no time” she ushered the lady out of the stable door and back towards her cottage, “Don’t worry, he’ll be fine” she added reassuringly.
“That old dear really is a spinster isn’t she” Kate remarked as she removed her clothes, “Doesn’t know a big donkey dick when she sees one” she laughed. “Yes, indeed!” Erica replied, “animal anatomy definitely isn’t her strong point” the two women laughed.
“Now then Pedro” Kate said, she got to her knees as Erica undressed behind her and grabbed the donkeys rock hard, 18-inch cock, “Let’s give you some much needed relief” Erica, now also naked, passed her a bottle of lubricant, the blonde squirted some onto the donkey’s dick massaging it quickly, the animal snorted and it’s hips twitched.
“He’s a big boy isn’t he?” Kate grinned, “He certainly is” Erica replied, she joined Kate on her knees in the straw so they were either side of Pedro then the two women rubbed the enormous dick with their hands and licked and sucked the end.
Precum leaked out of the Donkey’s dick and Kate licked it up before kissing Erica and sharing the creamy liquid with her, “Yum!” she giggled, “That’s tasty” Erica nodded in agreement and licked more from the cock as it seeped out, the women kissed again and began to finger one another while continuing to jerk the donkey.
Their kissing reached fever pitch as they fingered one another harder, more fingers were inserted until they were fisting each other, their pussies making wet noises and their faces were right in front of the Donkeys big dick and large swollen balls, “I’m cumming!” Kate announced, “Fuck yes!” Erica was too.
Suddenly the animal let out a loud braying sound and squirted a huge fountain of cum all over Erica and Kate’s faces. The women gasped in ecstasy, fist fucking each other frantically as they climaxed, Pedro’s cum splashed over their faces and down onto their tits as the Donkey sprayed them, they opened their mouths as the flood subsided a little and drank down as much spunk as they could, they continued to fuck one another until they were fisting each other to another orgasm, “Yes, I’m cumming again” Erica gasped, “Oh fuck! Me too!” Kate moaned and cum dripped off their shuddering bodies as they climaxed together.
Pedro wandered over to his feed basket and was quietly chewing some hay, “He seems better now” Kate remarked, “Yes” Erica agreed, “look, there’s a hose over there, we’d better rinse this cum off and clean up a bit before we get the old dear” Kate nodded, “Hope she doesn’t notice anything” she laughed.
Fortunately the Old Lady was so pleased that Pedro looked “Back to his old self” that she didn’t seem to notice that the Vet and her assistant were now a little damp. “Oh how can I thank you?” she said as she hugged the animals neck.
“Well” Erica said in her serious vet voice, “Donkeys can be prone to stress sometimes if they don’t get a regular check up so I recommend that we come and visit every three…” she looked at Kate who held up two fingers behind the lady’s back, “No, every two weeks and give him a look over and he’ll be fine and have a long, happy life I’m sure”
“In that case I’ll see you in two weeks then” the Old Lady beamed, “Perfect” Erica smiled, “Kate will contact you and make the appointment as soon as we get back to the clinic” they headed back to the car, “Have a nice day” she added but the old lady was hugging Pedro again, obviously happy, as was Pedro!
“I think I’ll be looking forward to that big dick every two weeks” Kate said, “Oh yes!” Erica agreed, “Me too” the pair drove back to the clinic to make the arrangements with smiles on their faces.
The End… until next time…
