(A/N please leave comments! I don't know if I'm doing alright or downright horrible without feed back!)
Sebastian continued his cleaning, moving from room to room and cleaning windows. He stood back and admired his work, a sick feeling arising in his stomach as threw a hand over his mouth, flying up the stairs and into the bathroom just in time to vomit into the toilet for the 7th time that day. He stood, flushing the toilet and beginning to brush his teeth. He stared at himself in the mirror, a pale face staring back at him. 'Surely he was just sick? No,' he thought, 'not even mortals stay sick for that long!' He sighed, vomiting again and standing, walking through the hallway suddenly a lot more tired than he remembered being just a few moments ago.
He smiled slightly, realizing that he was done with his chores and that he could finally rest. His thoughts were disturbed as a red blur launched past him, "Bassy~" it cooed, Grelle wrapping his arms around Sebastian's neck. Sebastian stared at him more blankly than usual, making no effort to shove him away. Grelle tilted his head, "Is everthing alright?" Sebastian nodded, "Indeed, just a tad tired." Grelle began to drag Sebastian towards his room, the demon putting a hand over his mouth again and desperately struggling away from Grelle.
Grelle began to drag him to his room, the butler feeling a sickening lurch in his stomach as he vomited, Grelle releasing him and jumping, taking a dainty hop back. Sebastian stood there coughing, Ciel walking in at having heard Grelle's yelling. "Sebastian? Are you alright?" Sebastian coughed, vomiting once more and stumbling back, "Yes, I-I am fine......" he breathed heavily, Ciel pushing him towards his room. He ordered Mey-Rin to clean it up, surprisingly doing it correctly the first time.
Sebastian lay curled up on his bed, wincing slightly at the realization his abs weren't exactly....... abs anymore. He curled into a protective ball, finally managing to grasp sleep. He woke up shaking slightly, a cool hand caressing his hair. Claude sat on the edge of the bed, gently smoothing his hair into place. Seeing Sebastian awake he began to stand, pulling his hand back, "I'm terribly sorry, I just wanted to check on you." Sebastian grabbed his hand gently, "C-Claude....?" The yellow eyed butler looked at him, "Yes?" Sebastian whimpered, "My head hurts......" Claude nodded and kissed his forehead, disappearing and reappearing with Ibuprofen and a glass of water. He smiled, waiting until he had taken the pills before running a hand over his forehead, humming quietly until he fell asleep.
Sebastian had also begun to notice he was hungry. Even more, he found he was rather hungry at frequent rates. He would go into the cabinets and search for food, something he could eat. Once, at around 12:13 in the morning he was searching, Ciel walking in, "What are you doing?" Sebastian jerked around, knocking a bottle of vinegar to the floor as it shattered with a crash. He gulped, "M-Making you a c-cake, my lord!" Ciel raised an eyebrow, "With cereal and vinegar?" Sebastian gave a sheepish nod, "At 12:13 IN THE MORNING!?" Another nod from Sebastian. Ciel grumbled, "At least make sure it tastes good." Sebastian prepared a sandwich, creeping upstairs.
Sebastian figured it would be better by now, that he would not be sick anymore. But, it actually got worse. The work was tiresome, and Sebastian had to work quickly to complete tasks. He had begun to welcome the nausea, aside from the times he didn't make it to the bathroom. He didn't eat in the night anymore, nor really eat at all.
Claude stepped in the window, expecting a waiting or sleeping Sebastian, but finding one of the worst things he could think of seeing. Sebastian sat curled up on the bed, fully dressed as a sign he had been there a while. He cried silently, shoulders rising and falling with every jagged breath. Claude walked over to the other side, sitting beside Sebastian as he pulled his lover to him, gently patting his back and running a hand through his hair. Sebastian didn't care about being quiet anymore as he leaned against Claude, burying his face in his chest as he sobbed, clinging to him. Claude hushed him quietly, "What's wrong?" Sebastian pulled back long enough to choke out, "If I was fat, would you still love me?" Claude nodded without hesitation as he pulled Sebastian onto his lap, laying on his side with Sebastian, a hand holding the butler's face and the other wrapped around his back.
