Special treatment

Attention: This story containes butts and dicks and gaping assholes. You have been warned... or probably invited right in if you clicked this story XD

The wheels of the medical cart made a regular squeaking noise as Sen pushed it through the hospital. He was on his way to the VPP wing. VPP standing for very perverted person. His job was to make the patients residing there feel better in very... unconventional ways.
He was dressed in a sexy nurse's outfit. The slender donkey couldn't really fill out the top part, being a male and all, but his ass gave the short skirt a real hard time keeping everything decent. He was not wearing any makeup so his normal grey fur contrasted nicely with the white/red nurse outfit.
Sen was walking closely behind his cart as that was the only way to conceal his massive erection poking out from under his skirt at the front. Making his way through the standard part of the hospital always put Sen on edge. There was only a thin sheet of fabric between unknowing visitors and patients  and his bare cock and arse. But it was the large vibrating buttplug that made it impossible fro him to calm down.
With a racing heart he crossed the main hall and headed to the door with a guard in front. "Someone must hear the buzzing noise of the plug!" Sen thought as he passed by a dozens of people inclusing whole families. But nobody reacted... at least as far as Sen noticed.
Blushing and panting Sen arrives at the door and gives the guard a nod. "Special treatment for patient 4 and 6." The guard nods back, but as Sen pushes the cart past him, he smacked the donkey's ass audibly making him cry out for a second. "Gah. Dorian. You ass!" Sen said, then added in a lower voice "I'll visit the security room after I'm done here. Be there early if you want more than one turn."
With that Sen enters the VPP wing and finally relaxes his stance. With his tail and thus his skirt raised, the buttplug is now exposed to onlookers. The few people he passes by now flash him a smile as they stare at his behind.
At room number 4 he makes a sharp turn and enters. There is only a single bed occupied and in it lies an adult male covered in bright red feathers. A few black markings on his face show that he is a cardinal. Sen walks up next to the bed and pulls the sheats down, exposing the nude bird's massive black penis. "Good evening Mr. Pulsar. How are you feeling today?" Sen inquires of the patient as he begins stroking the shaft that quickly begins to grow hard in his skilled hands. "Much better. Fever is down and the lightheadedness is gone too. Just my throat is still a bit sore."
"You are making a quick recovery then. Very good." Then the donkey nurse wraps his lips around the tip of the monster cock, almost as large as one of Sen's legs, and thrusts his head downwards. He swallows the whole shaft with surprising ease, denting his belly out in the process. Then for several seconds his head is burried in the crotch of Pulsar, deep throating him to the hilt. Following that he comes up and the dick pops out of his mouth with a satisfyingly lewd sound.
"You taste very healthy already. Did you climax today?". The well hung bird replied "Only half a dozen times. I didn't want to overdo it when I am still recovering." With a smile Sen moves to the head of the bed "That is good. We don't want you to have a relapse. Now lets take care of your sore throat." Sen lets his equine erection rise up from between his legs and points it at Pulsar's head. "Please take orally."
Without hesitation the slutty cardinal gulps down the black/white spotted shaft. Just as the donkey before, the bird has no problem swallowing the large erection down to the hilt as well. Sen grabs Pulsar's head and starts thrusting into it. A sizeable bulge moves up and down his throat and chest, making both patient and nurse moan satisfiedly. The hot donkey shaft, covered in ample amounts of precum works wonders on the bird's throat as it massages the sore areas. "Mr. Pulsar! M-my medication is almost ready. Please make s-sure y-you swallow it all!" Sen stutters between heavy breaths as his dick is expertly sucked by the slutty cardinal.
The equine cock pulses and throbs as Sen reaches climax and unloads a big load of medicine into the patient's throat. With big slow gulps the horny bird makes shure not a single drop is wasted, the donkey semen coating every inch, from his mouth down to his stomach. Certainly not a bitter pill to swallow. "Aaaahhh!" Sen moans loudly as his dick slides out of the patient's beak. "Oh my. Every last drop! I rarely have such well-behaved patients..." then adds in a lower voice"...or such expert cock suckers."
With slightly wobbly legs he walks back to the medical cart, giving the rock hard bird dick a quick stroke as he passes by. "Now, I would love to take your word for it, but unfortunately I will have to measure your temperature to confirm you have no more fever." As he talks, Sen pulls out a thermometer, several feet long and as thick as a leg. "But if you are a good boy I will give you a nice treat."
"No worries. You just have to do your job. But the doctor recommended a different thermometer. He said this size does not fit me properly and may give wrong readings. He put the right one under my bed." Surprised the donkey nurse turns around and has a look under the bed. "I see. Who am I to argue with a doctor?" He puts the old thermometer back and pulls out the new one from under the bed. It was only a little longer then the other, but the diameter was larger than the donkey's head.
"Could you spread your legs please?" the donkey asks and is greated by an anal ring as black as the cock and balls dangling above it. Sen leans close and pushes his tongue into the back entrance and explores it with his tongue. The anal ring quickly loosens and swells engulfing almost all of Sen's head, before he notices and pulls back. "You certainly have an inviting personality!" the donkey jokes and reaches for the thermometer.
"Everyone is welcome in my backsiii-oooh!" Pulsar moans loudly as the incredibly massive instrument stretches his asshole wide. The first two feet go in easily, but after that Sen has to put some muscle into it. A large bulge wanders from the crotch upwards, clearly visible underneath the cardinal's six-pack. The bird's cock begins leaking cum almost immediatly after being penetrated in this way. "Fuck yes, that hits all the right spots. Deeper. Deeper! The last one chickened out half way through."
"You don't have to worry about that with me Mr. Pulsar!" Eager to please his nursling Sen leans forward and pushes with his whole body. The hosptial bed slides back a few inches, even though the breaks are on and is only stopped by the wall. Now with an unmovable object blocking the path, the thermometer is pushed in whole in one go... along with Sen's hands up to the elbow. "Hng!" Pulsar grunts as a climax rocks his body, and his cock erupts like a geysir painting the ceiling white.
As the horny donkey sees this he quickly pulls his arms out of the ass and grabs the black cock and pops it into his mouth. Gulping loudly, he directs the stream of hot spunk down into his belly. Luckily Sen only cought the last part of the climax, otherwise he'd have inflated like a balloon. Even so, his belly is visibly bloated after he lets go of the cock and catches his breath. "Mr. Pulsar! Terribly sorry. I wasted so much of your delicious cum. Please let me make it up to you. You definitely earned this treat!"
While Pulsar catches his breath after the intense climax, Sen climbs onto the bed and sits down on his chest, with the donkey's ass pointing to his head. "Please enjoy this donut specially prepared for you by courtsey of the 'Slippery Slope medical hospital'!" and with that Sen pulls out his buttplug and presents the gaping hole to the horny bird. With a smile Pulsar digs in, his ass still stuffed with the huge instrument, and eats out the asses' ass.
White, sticky semen is dripping down the ceiling as the donkey's rectum gets thoroughly explored by the bird tongue. Certainly an unusual sensation, especially the beak poking in and out as Pulsar goes deeper into the ass. So it was no surprise that the equine's penis soon is erect again and presses against the patients belly bulge. As his asshole is rimmed Sen gently caresses the semi hard shaft of the fuck bird. Lost in the moment the two enjoy each other's company in a few more ways, before it was time to go.
As the horny donkey climbs off he leaves a red spot on the bird's chest, the rest is covered in white cum. Sen is similarly covered... as well as the whole side of the room. "Mr. Pulsar, it was a pleasure serving you. I'll send in some cleaners later. Now, could you please plug me up again?" the donkey says and bends over spreading his well licked asshole.
"With pleasure!" The cardinal reached for the plug and slid it into the gaping hole in the donkey's behind. But he doesn't stop as the base hits the anal ring, with a quick thrust he shoves the whole plug several feet up the donkey's intestine. "Ahhh! Mr. Pulsar! Not so far up! Now I can't get it out!" the donkey exclaims "Well that's the idea. Enjoy the deep tingling." Sen blushes "T-thank you. See you."
Drenched in cum, the cock erect and throbbing once more, his belly bloated and a gaping hole between his ass cheeks Sen pushes his cart out the room leaving a trail of white 'medicine'. "On to the next patient." he mutters and makes a turn in the hallway.
