Prompt: what about Charles or Erik getting sick and the other one taking care of him? youre amazing btw for taking requests :D
What most humans don't realize is that a mutant's power is just like any other part of him, so when he gets sick, he loses control. Charles, however, understood this – both from his research and from experience. So when Erik came down with the flu, he knew what he was getting himself into.
Charles knocked lightly on the door and pushed it open. Erik was lying in the center of their bed, the covers tucked tightly up to his chin, his nose pink and his cheeks flushed. He looked up at Charles with dull eyes.
"I made you some soup," Charles said. "It's your favorite – classic chicken noodle soup without the chicken."
"Thank you," Erik rasped. He made a move to take his arms out of the sheets.
"Don't," Charles said. "I've got it."
Erik didn't reply, just gazed at Charles gratefully as he climbed onto the bed and sat cross-legged beside him, soup poised and spoon at the ready. Erik opened his mouth and loudly slurped the soup, making a low, contented noise as the warm soup slipped down his aching throat.
They had barely gotten through five spoonfuls with Erik's nose began to twitch. Charles quickly set the soup down and lunged for a pillow, throwing it in front of his face just in time to shield him from the onslaught of metal that flew at him when Erik sneezed.
Erik groaned. "I'm so sorry."
Charles peeked out from behind the pillow, laughing so hard that he had to wait a moment before he could speak. "Don't be, baby. And bless you." He reached for the soup and then halted. "I think we're going to need a new spoon, though." He meekly picked up the spoon and held it between his thumb and forefinger. It had been folded in half during Erik's sneeze.
"Actually…I don't think I can stomach anymore," Erik mumbled. "I'm sorry; I know you made it specially for me – "
"Don't worry. All the more for me," Charles said lightly. "Oh, wait. Before I go, you've got a little something – " He bent forward towards Erik.
"No, Charles. I'll get you sick."
Charles smiled as his lips met Erik's. He kissed him softly, and then leaned over, kissed him once more on the cheek, and whispered, "Worth every sniffle."
