Author's Note
Sunset Heights is owned by my friend Andrew. He challenged me to write some clop of his OC, and I accepted. This is also the second time I have used the Rule 63 version of Doctor Haywick - my OC - in any story of mine... and it is also her first appearance in a clopfic. 
Anyway, the following story is clichéd as hell, for reasons that you will soon discover.
Enjoy. Or not, that's up to you.
One-Shot
The sounds of hoofsteps and conversations echoed through the corridors of Ponyville General Hospital, while the pungent smell of disinfectant invaded the nostrils of anypony who was unfortunate enough to be near the cleaning staff who were using it.
Amidst the hustle and bustle, one of the nurses was making her rounds; checking in on the few patients being cared for. She left each room with a smile and a wave, a feeling of happiness welling up inside her with each pony she helped.
She approached the last room on the ward, pausing to look at the patient details which were written on a whiteboard which was attached to the door.
"Sunset Heights," she mused. "A pegasus stallion, brought into Accident and Emergency after a crash landing which broke both his wings and his two front legs." She winced. "Poor guy. Well, then, I'd better see if he needs anything."
She knocked on the door and walked into the room to see the stallion in the bed. He was orange with a two-tone orange mane and tail, with both his forelegs held up by splints and bandages wrapped around both wings. At the sound of the door opening, he looked over to see the nurse walking in.
"Good evening, Sunset," she said. "My name is Nurse Haywick, and I am one of the staff responsible for patient care tonight. Would you like me to get you anything?"
"Hello, Nurse Haywick," Sunset replied. "As a matter of fact, there is something you can get me. Some dinner would be very much appreciated right now."
"Of course." Haywick nodded. "Is there anything in particular that you would like me to get you?"
"It doesn't matter, to be honest." Sunset shrugged as best he could. "As long as you blend it into a paste that I can drink. If I can be honest, I'd rather not waste your time by making you feed me."
"That's understandable," Haywick said. "Very well, Sunset, I shall go and see about getting something prepared for you. I'll be back in about five minutes."
"There's no rush," Sunset replied. "Take your time, it's not like I'm going anywhere any time soon." He flashed her a smile.
Haywick giggled and left the room, proceeding to the kitchen further down the corridor. She prepared a meal, which she then put through the blender, and put the resulting goop into a glass with a straw. Satisfied with the result, she picked up the glass in her levitation aura and returned to the room.
"Here you go, Sunset," she said, as she closed the door quietly behind her. "Today's special is a blended vegetable lasagne. Given that you can't hold anything, would you like me to hold the glass for you while you drink it?"
Sunset looked at his forelegs, encased in plaster, and sighed. "Damn, I forgot about that," he muttered. "Yes please, Nurse, I'd appreciate if you could hold the glass for me."
Haywick smiled and levitated the glass over, watching as Sunset strained to reach it. As it got closer, he made one final attempt to grip the elusive straw between his teeth — only to knock the glass out of the air and empty the contents all over him.
Haywick gasped as Sunset let out a creative volley of curse words.
"Oh, dear!" she said. "I am so sorry, Sunset. I'll get some wipes."
She quickly walked over to a cabinet, listening to Sunset's groans of agony. Opening the door, she started to dig around inside.
"Disinfectant, bandages, plasters..." Haywick continued searching, while Sunset's groans suddenly stopped. "Splints, bedpan... ah, here we go, napkins! Why they're in here, I don't know, but I'm glad they—" She stopped talking as she noticed the silence. "Um, Sunset, are you okay? You've stopped groaning." Sunset didn't reply, so Haywick glanced over her shoulder — and gasped.
Clearly visible was Sunset's throbbing erection, which he had tried to hide by kicking his blanket over it, only for it to end up on the floor. After pondering how he got it, Haywick was quick to realise that she was bent over in such a way as to give the stallion a clear view of her marehood.
"Oh, my," she breathed. "This is most unprofessional of me."
"I am so sorry, Nurse," Sunset said hastily. "I tried to cover it up, but – as you can no doubt see – I failed miserably."
Haywick straightened herself and turned around. "Don't worry about it," she said. "It's perfectly natural for a stallion to get aroused when a mare is... presenting herself in that manner." She smiled and winked at him. "And, to be honest, I actually find it quite flattering that you think of me this way."
Sunset blinked in surprise. "Y-you do?" he asked.
Haywick retrieved the napkins from the cupboard, closing it as she walked back over to the bed, and began cleaning the mess from Sunset's fur. "Sure I do," she replied. "I can't remember the last time I had a stallion compliment me on my looks, because normally I'm tired out after my shift. But I have to say that this—" she motioned at Sunset's still-present erection "—is quite the compliment." She flashed him a smile to show that she was joking.
"Well... you are an attractive mare, I'll give you that. It's just... it's been a while since I last, er, 'got some relief.'" Sunset chuckled. "If you know what I mean."
"Of course I know what you mean." Haywick finished cleaning off the last of the spillage. "There we go, all better. I'll get a replacement meal made up for you."
"Uh, before you do that..." Sunset motioned towards the blanket on the floor. "I don't suppose you could pick that up for me?" Haywick wordlessly picked up the blanket from the floor and placed it on the bed, concealing the bulge he was packing. "Thank you very much."
"Don't mention it." Haywick walked over to the door. "I'll be back in a couple of minutes with a fresh glass. When I come back... make sure to take it easy this time, okay?"
Haywick giggled as Sunset rolled his eyes, then left the room and returned to the kitchen. After making another blended lasagne, she returned to her patient.
"All right, Sunset, here you go." She levitated the glass and straw over to him, holding it a few inches from his face. "Take your time, and enjoy. It's actually quite palatable for hospital food."
The next few minutes passed by in silence, save for the occasional slurp from Sunset, and soon the stallion had drained the contents of the glass. He stifled a belch and sighed contentedly while Haywick put it to one side.
"That hit the spot," he said. "Thanks for your help, Nurse, I really appreciate it. You didn't have to go to all this effort just for me."
"I'd do the same for any of my patients, Sunset." Haywick stuck her tongue out at him. "So you're not exactly special."
"Speaking of your other patients," Sunset said. "You'd better resume your rounds. I'll be fine, for now at least."
"Actually, you were my last one for tonight." Haywick looked at the clock. "My shift ended ten minutes ago... I just wanted to make sure you were all settled first."
Sunset looked surprised. "Really? That's nice of you." he shifted a little. "But you don't need to worry about me, honest."
Haywick raised an eyebrow. "I can see that you've still got an erection," she said. "Though it's surprising that it's lasted this long."
"As I said earlier," Sunset replied. "You're an attractive mare, and I am a stallion who can't remember the last time he got anything like what you were showing me earlier." He smiled. "It was, if I can be honest, quite the show."
Haywick blushed, her eyes darting between Sunset's own eyes and the blanket which was covering his stiffness. After a moment of awkward silence, she spoke.
"Do you want some help with that?"
Sunset's eyes widened as the words left her mouth, and he looked at the nurse in total shock. She looked away, her blush deepening, and rubbed one foreleg against the other. Sunset looked at his erection, up at the nurse, and sighed.
"Please."
Haywick nodded and walked over to the bed, removing the blanket and tossing it aside to allow Sunset's shaft to spring up. A burst of magic locked the door as she climbed onto the bed and eagerly pressed her lips against Sunset's.
The two of them explored each other's mouths freely, while Haywick traced a hoof up and down Sunset's cock. His groans of pleasure muffled, the stallion clenched his eyes shut while the mare began to tenderly rub his shaft.
Ending the kiss, Haywick moved downwards – trailing kisses along Sunset's chest as she did so – and brought her muzzle to his dick. She put her tongue out and slowly licked it from balls to head, kissing the latter once she reached it. Her tongue worked his length with ease, coating him in a layer of saliva.
Haywick rolled onto her side, showing Sunset that her marehood was slightly wet with arousal. She reached between her hind legs with her free forehoof and began rubbing her slit, little moans escaping her lips, while Sunset could only look on in awe. He looked at the bandages on his forelegs and sighed.
"If only these damned things weren't here..." he grumbled. "I feel so useless, sitting here while you – aah – do all the work."
Haywick stopped licking him, choosing instead to rub him slowly. "It's all right," she replied. "I don't mind, honest. Just enjoy yourself, Sunset, because I don't think I have to tell you that I don't offer this level of service to my other patients."
Sunset nodded, watching as Haywick finally took his length into her waiting mouth. Inch by inch disappeared down her throat until she finally got to his ballsack, which she nuzzled contentedly.
The pleasure coursing through Sunset's veins intensified further when Haywick took him out of her, only to dive back down again. When she wasn't deepthroating him, she was bobbing her head back and forth, her throat muscles massaging the stallion's rod and coaxing him to spill his seed.
Which, after several minutes, he almost did — only for Haywick to stop and take him fully out of her mouth with a wet pop.
"We're not at that part yet," she said as she stood up on her hind legs. "There's just one more thing we have to do first."
Haywick straddled Sunset and positioned her soaked entrance above his equally as slick member. She put her forehooves on the pegasus' sides – being careful to avoid his wings – and painstakingly began to lower herself onto him. She let out a gasp as her lips parted to make way for the massive guest, but continued lowering herself until she was sitting on his lap. Both stallion and mare moaned as their bodies were joined.
"Holy..." Sunset grunted. "You... you're so fucking tight."
"It's been a while," Haywick panted. "Oh, sweet Celestia, I have been waiting for something like this for so long!"
"You and me both," Sunset replied. "Oh, man, you're so warm..."
Haywick giggled, giving Sunset a peck on the cheek as she moved herself upwards. As she reached the top of his length, she would slam back down again. Up and down, up and down, the cycle continued for what felt like hours to the two.
Heavy balls slapping against soaked pussy, pants and moans of delight, grunting and groaning as Sunset forced himself to thrust into the needy mare above him... the room was full of the sounds and smells of lustful sex.
"Oh, yeah," Haywick moaned. "Fuck me, Sunset, fuck me harder!"
"I don't think... I can take much... more of this!" Sunset looked up at the mare riding him, their eyes locking. "By Celestia, do you have any idea how gorgeous you are?"
Haywick responded by sticking her tongue in his mouth again and increasing the speed of her bouncing. Sunset ground his teeth together until they hurt, slamming his cock into her a few more tired times before he felt himself explode inside the nurse's greedy and inviting entrance.
"Fuuuuuuuuuuuuuuuuuuuck!" Haywick screamed. "Fuck yes!"
Sunset kept thrusting, driven by a primal instinct, relishing the feeling of Haywick's vaginal walls still attempting to milk him dry. Eventually he stopped, groaning as Haywick got off him and lay at the foot of the bed.
"That was..." Haywick sighed. "That was incredible."
"I know." Sunset grinned. "And you weren't too bad yourself."
"I rocked your world, and you know it." Haywick slowly dragged herself up and gave Sunset one final, chaste, kiss. "Thank you for telling me that I'm attractive."
Sunset returned the kiss. "And thank you for being the best nurse ever." he chuckled. "I'll be sure to give you a review that—" he glanced at Haywick's pussy, filled with his cum, and grinned wickedly, "—overflows with positivity."
"I'd like that," Haywick replied. "But right now, it goes without saying that I need to clean up in here."
Sunset looked at the cum-soaked sheets. "Ah, of course," he said. "Since I can't help, I'll try my best to stay out of your way."
"The sheets can wait." Haywick bopped Sunset on the nose. "Right now, though, I think somepony could use a sponge bath."
Sunset didn't reply, choosing instead to nod feverishly as Haywick undid the straps holding his forelegs in place. Once free, he held onto the nurse for support as she guided him to the bathroom, with her tail held up as a reminder of what had just transpired — as well as a reminder of what else was to come.
