Sunburst slowly awoke from his daze only to find himself tied up to a chair. It was very sturdy and comfortable, yet that offered him no resolve to the utter blackness around him. This wasn't helped by the strange bits of laughter and munching sounds he was hearing. His body tensed and pulled at his bonds, but found them tight. His mind raced, and he called out, "What is going on here? Is anyone there?"

The sudden feeling of something soft and fluffy brushed against his shoulder, causing him to jump slightly in the chair. On the other side, a less bouncy but just as firm roundness pushed against his neck. The sensation caused his breath to catch, and he heard the two mares giggling. Having enough of this mystery and doubt he lit up his horn and revealed them.

"We're your nurses!" they announced together, though only one was actually touching him.

"Wh-what's going on?" His eyes raced around at the sight of Scootaloo's two guardians. The orange mare with plenty of curves and bust, Holiday. The green mare with a more modest bust and slender frame, Lofty. They were both wearing white dresses with black stockings and heels, along with a nurses' hat. Holiday had a large bouquet of flowers and Lofty held a clipboard, both smiling at him.

"We are here to take care of you, Sir!" They both spoke together, almost in perfect sync.

"What are you talking about?" Sunburst shivered away in confusion as the mares bounced their cleavages in his view, making it impossible to focus. He turned away as far as he could, as this was wrong on so many levels.

Lofty spoke up. "I have your charts here." She then lifted her clipboard and showed it to him. There were all sorts of notes and drawings, and the only thing he could really see was the title that read, "Patient: Sunburst."

"You're suffering from a very serious case of loneliness, Mr. Sunburst." Holiday shoved the flowers in his face.

"W-what? Loneliness?" He turned back and looked at the chart. The more he read the more his cheeks flushed, realizing all the notes were about his personal life. In fact, several pages straight from his own diary had been stapled to the board. "When did you read my diary?"

"Oh, I hope you don't mind. I thought it would help me learn a little bit about you." Holiday giggled, and leaned closer to him, her soft and plump breasts pressing against his shoulder.

"We found it in your office!" On cue, Lofty turned on the lights and revealed where they were. The three were still deep within the library. The moans outside the room from the other couple Sunburst witnessed before arriving were still going firm.

"Sunburst, you'll be my favorite patient," Holiday kissed him on the cheek. "I'm going to check your vital signs now." She put the bouquet down next to him and lifted his shirt. With one hand on Sunburst's chest, she felt around for his heart rate with her bare hand.

"Now, Nurse Holiday, you know we can't do that without proper protection. Let's start with the thermometer." Lofty lifted a measuring stick, probing it around like she was taking someone's temperature. "Open your mouth, Sir. Don't be shy." She cupped Sunburst's chin and forced him to face her. She then reached around and grabbed the measuring stick from her fellow nurse and shoved it into Sunburst's mouth like it was a thermometer.

It quickly became clear neither of them were thinking straight at all. The stallion didn't know what to think as the nurses continued to play with him. Holiday kept feeling him up, even groping his nipples as the two began to undress him. Lofty was pulling apart his shirt collar and tracing her lips closer to his neck. Sunburst could only whimper as he was unable to fight back, his mouth occupied with the measuring stick and his legs still trapped.

"Your blood pressure is high, sir. We better check for swelling." Holiday pulled off her dress, revealing the tight bra and panties underneath. They were pure white, and she wore a matching garter belt that helped keep her stockings up.

Holiday and Lofty looked at each other for a second before smiling back at Sunburst. "Oh, but Sir, you must. Your life is in danger if you don't!" They pleaded in sync while grabbing his pants.

"W-wait, no! No, stop!" Sunburst's eyes widened in horror as his pants were unzipped. He had to think of a way out of this. Scanning over the room, he spotted the plate of food. Quickly remembering what he discovered previously, he assumed they must have been poisoned too. This would be his only chance. Taking the plate in his spell, he lifted upward and dropped it over Holiday's head. The mare's hat fell off and the food splattered all over her.

"Hey!" Holiday fell backward. The crash to the floor also revealed how loose her clothing was. The bra snapped apart and exposed her naked chest, The panties and stockings popped off soon after.

Sunburst winced his eyes as tightly shut as possible.

"Holiday, I'm so sorry. Here, let me clean that off." Lofty quickly ran off and grabbed a towel from a table. However, seeing her naked form left her even more aroused. Her eyes lingered at her partner's breasts, and grabbed them violently. Holiday squeaked as she was pushed onto her back. The towel dropped as Lofty started kissing her neck.

"L-Lofty, stop! We have a patient."

"No, Holiday, please. Let him watch!"

Sunburst's ears flickered in horror as he slowly opened his eyes. Sure enough, he was now witnessing the two nurses making out. Lofty had her hand on Holiday's chest, squeezing it hard. While Holiday was pulling Lofty's dress off. It was a shocking and horrifying sight for the poor stallion. He could see everything. "You can't do this to each other! You're sisters!" He tried to reason with them.

"You poor fool, only in censored cartoons!" Lofty broke the kiss and dropped her bra too. Leaning down, she dragged her tongue along Holiday's belly.

"We are wives, that's kinkier!" Holiday smiled, looking directly at the stallion, squeezing her nipples as her beloved reached the perfect spot.

"And we haven't had a hard stallion for years." Lofty sank her tongue into Holiday's pussy, leaving her wife shrieking.

"No!" Sunburst couldn't believe it, and looked away. He couldn't deny it anymore, both were beyond saving now. These two were crazy and completely consumed by the plague infecting the school. It was time for him to leave. As the moans and cries of the nurses filled the room, he focused on his own bonds.

Now that they were away from him, he could focus his magic on untying his legs. With his lower half free he was able to stand, though his arms were still bound together. Turning around in the chair, he pinned it on top of the two lovers. They both cried out and looked at him in confusion. Sunburst took a step back and used his magic to tie all the ropes around them and the chair. The two were now trapped, allowing him to stand and zip his pants back up.

"Sir, you're not leaving us, are you?" Lofty begged, her arms wrapped around the chair.

"Please, we just want to make you feel good." Holiday was leaning forward, her breasts rubbing against the seat.

"Nope, nope, nope!!" He rushed over to the door. However, he was stopped by the moans of the other couple bracing the other side of it. Hearing them climax so loud, Sunburst quickly changed direction and headed for the window. He unlocked it and pried the window open.

"What about your diary pages?" The two mares complained. "Your heart belongs to two mares... but they aren't us."

"Wait, why does that matter?" He stopped and thought about it. He didn't know why they would bring this up now. Were they trying to lure him back in with temptations of picturing those two in place of these two. "No!" He waved his head back and forth, fighting off the thought. "I can't let myself get infected too." Sunburst climbed out the window and hopped down into the garden below.

There he was surprised by two other females. Luckily, they weren't the two mentioned in his diary. He held up a nearby branch in case they were infected too and swung it about. "Don't touch me! Stay away! I'm not going to be a part of this sickness."

The two mares held up their hands in surrender and shook their heads. "Calm down, we aren't one of them!" The yak yelled back in a familiar tone.

"Yeah, we barely escaped the rest of those vultures!" The hippogriff agreed, and both backed away.

"Huh?" Sunburst finally stopped swinging the branch around and took a good look at the two. Sure enough, it was two former students turned teachers, Silverstream and Yona. Both were wearing the same black clothes as him. "Oh thank goodness, it's just you two." His eyebrows raised. "Wait, where is Gallus and Sandbar?"

"We couldn't save them!" Yona threw out her arms in a big display of panic.

"Ocellus too, poor mare." Silverstream hung her head.

"Not good..." Sunburst's tone dropped. Realizing how quickly this was spreading, he had to come up with a way to stop this before it reached beyond the school. "Follow me." He led the two out of the garden and across the field, heading back for his lab on the outskirts of the campus.

******

Yeah, Smolder and her friend will still be appearing in later chapters, I just wanted to include the rest of the student six as well. Plus it kind of cool to nice not everypony got infected.
