Wings of a Butterfly

Chapter One

Taking hold of the quivering form beneath him by the hips, Sebastian sensually traced bruises with his tongue.

Ciel gasped and fell to his forearms, his face flushed and his arousal weeping as his boyfriend worked down the blotched expanse of his back. Each bruise that was pressed upon elicited a small pain, but small kisses to each one soothed the skin, bringing him more pleasure.

Sapphire eyes slipped close and Ciel whimpered as large hands roamed over his ass, making his toes curl. Sweat beaded upon his forehead as his legs were softly nudged apart, Sebastian's tongue never ceasing its journey along his skin.

Hot breath against his entrance made Ciel nearly lose it, but it was the tongue he had come to love so much that undid him. A breathy moan escaped his lips, only to be smothered into the naked mattress. His spine curved as he pressed back for more, never-minding the small aches it caused.

There was something they were supposed to actually be doing, but Ciel had lost track of the time the minute Sebastian pushed him onto the bed. His mind was so muddled now; he couldn't recall anything of importance other than encouraging his boyfriend to probe deeper.

The warmth left his rear for but a moment until Sebastian draped himself over Ciel. His knees trembling, Ciel lightly clawed at the mattress as his boyfriend took to nibbling his ear at the same moment he gripped his throbbing erection.

"Baby…" came the lust-drowned call, making Ciel shudder the moment he felt Sebastian start to slowly rut against his inner thigh.

The heat within his body only swelled as the same name was whispered again and again into his ear, the hand gripping him stroking slower and slower.

"P-please…" Ciel begged, one of hands moving to grasp Sebastian's, the tips of his fingers folding into the grooves of the other's knuckles. "Please, Seb-Sebastian…!"

Allowing their hands to lace together, the elder finally stopped his teasing and captured Ciel's mouth in a hot and languid kiss. His free hand moved along the boy's side, intending to roll him over, but Ciel dug his knees into the mattress firmly, silently telling him no. Understanding, and with one last lick to a smooth lower lip, Sebastian moved back.

Most of the pain was not caused by his boyfriend. Ciel tried with all his might to loosen his shoulders as he felt his bottom half spread, but the pleasure was too much to handle all at once. He pressed the side of his face into the bed, surrounding his head with thin arms and sighing as he felt a hand gently run up his spine, wordlessly asking if he was okay.

A roll of the hips was enough to encourage Sebastian to start moving. He was careful to begin though, not wanting to cause Ciel any more pain. Yet within moments all his worried thoughts were wiped clean from his mind as he focused on the heat, the tension, and the absolute pleasure.

Ciel cried out with each thrust that hit his center of pleasure. His eyes were closed and his brows knit together as he pushed back in time to his boyfriend, his breaths completely ragged and hot against the moist fabric. "M-more…Se-Sebas-tian…mmh!"

Pumping Ciel to his own thrusts, Sebastian could feel the heat which had pooled in his belly starting to coil with vigor. His boyfriend was starting to noticeably unravel beneath him as he quickened their pace, causing Ciel to tense with a gasp before arching his slicked body against his own.

Ciel was the one to come first, crying out Sebastian's name so sweetly that said boyfriend couldn't hold back any longer. Stiffening in the height of his pleasure, Sebastian released, forgetting to be mindful of his grip on Ciel's slender hips.

Cradling his boyfriend into the curve of his own body, Sebastian calmed his breathing slowly as he wrapped his arms around Ciel's thin waist. Their body heat mingling pleasantly, they merely enjoyed one another's presence in their afterglow. It was when Sebastian's eyes were starting to droop that Ciel turned to face him.

Those large blue eyes that he had come to adore were still hazy, but Sebastian could tell that Ciel was far from slipping off into blissful sleep. He ran a hand through damp slate blue locks. "What is it, baby?" he murmured, leaning ever so slightly to plant a kiss on his boyfriend's forehead.

Cuddling further into the broad chest with a content sigh, Ciel replied drowsily, "You haven't even finished unpacking…"

The aroma of grilled cheese had filled the apartment by the time Ciel came out of the bedroom, cleanly washed and dressed in fresh clothes. Late afternoon sunlight lit most of the apartment, but Sebastian had turned on the two lamps that had been previously unpacked, as well as having flicked the kitchen lights on.

Going to the small round table Ciel slumped down in a chair and watched as Sebastian moved this way and that, placing two glasses and two plates on the table, and then flipping their cheesy meal in the frying pan. He smiled softly to himself, loving the way his boyfriend moved about so fluidly.

"You brought your toothbrush, right?" Sebastian asked over his shoulder.

Ciel nodded, pulling one of his legs up onto the chair so his knee was pressed between his chest and the edge of the table. "I can eat grilled cheese, you know," he replied.

Sebastian huffed with a smile. Ciel often told him he was like a worried mother; Sebastian had only just turned eighteen. "I hardly think your mother would want to pay for new braces if you get yours all messed up by eating something sticky."

Ciel shrugged. The long relationship with his braces was almost over anyway.

Letting his boyfriend concentrate on his cooking, Ciel glanced to the living room. Boxes were piled all around, some open, others still taped up and labeled. Sebastian's mother and father had been here early in the morning to help unload the family van and heavier furniture. Ciel had come around noon to help but his mere presence apparently became a happy distraction for Sebastian.

While Sebastian's actual birthday had only been less than two weeks ago, the notion of him having his own apartment had been in the works for months. From what he was told, Sebastian's parents even encouraged him to move out. Not because they didn't want him around – their son already had the desire to leave. He craved his own independence, and thought that the earlier he started, the better off he'd be in the long run.

Ciel didn't think that it was an entirely bad idea. Although Sebastian was still a senior in high school, a transition now would be beneficial to when he started college. He already had a steady job at a close-by convenient store, which helped pay some of the rent and bills. Of course he wasn't entirely left to fend for himself, for his parents had decided to help him until he was at least halfway through college.

The sound of Sebastian pouring their drinks brought Ciel back to dinner. Sitting tight, he waited until both plates were covered with the warm sandwiches. When his boyfriend sat down, he offered a small smile before digging in to the scrumptious meal.

"Are you staying over?" Sebastian asked.

Chewing, Ciel shook his head. "I told mum I'd come home," he replied through half a mouthful, ignoring the sappily-adoring smile which widened his boyfriend's face. Curling even more on the chair, he changed the subject. "When are you gonna finish unpacking?"

Sebastian shrugged, lazily glancing around the cluttered living space. "I have to work tomorrow so…"

"And Monday, too?"

"Through Thursday."

Sebastian didn't miss the way those blue gems attached to the table, or how Ciel suddenly became fixated to his half-eaten grilled cheese sandwich. He felt guilt for all but a minute, but he knew Ciel understood the situation.

Standing and leaving his food on the plate, Sebastian went to his boyfriend. Catching the boy's chin and tilting it up and back, he pressed a warm and reassuring kiss to Ciel's lips. He was sure it wouldn't completely quell Ciel's sadness, but it was the best he could offer for now. Sebastian would do anything to lift that gloomy expression from Ciel's delicate face.

"Are you free Friday night?" he asked, closing his eyes as fingers hesitantly gripped the collar of his loose shirt, gently tugging him back. Ciel initiated the kiss this time, and Sebastian felt the passion the boy would so often hide away in it.

"Saturday would be better," Ciel sighed in a whisper. Sebastian frowned and moved to pull his chair closer so he could sit next to his boyfriend. He wanted to protest, suggest they meet somewhere in school – but he knew Ciel wouldn't have any of that.

A week.

He wouldn't be the only one to dislike it, and they'd gone through it before. Sebastian knew this would happen the moment he signed the papers for the apartment, he knew he would have to ask for more hours. But he had the hope it would get better over time.

Smiling at his own thoughts, Sebastian nodded. "It's a date."

Sitting in the nurse's office was not something unfamiliar to Ciel. He had grown to find the thin, lumpy and cold beds comfortable. The antiseptic smell had gone away, and the two nurses themselves had become more tolerable with each visit. In a way, the small office which echoed terrible eighties music had become a haven of sorts to Ciel.

Today's case had been the usual "accident" in gym class. Sports were never his forte and it somehow only seemed just to punish him for his lack of ability. A rowdy game of indoor lacrosse ended in a rather large gash on his arm and an achy spot under his jaw. Currently the middle-aged nurse was speculating whether or not he'd need stitches.

He hoped to be spared of another walk-in visit. Ciel knew the moment that itchy thread was woven through his skin that he would stop at nothing to pick it out.

Popping small bubbles with the gum she chewed, the nurse clucked her tongue and informed Ciel that stitches wouldn't be of issue. Some antibiotic ointment and bandages would do him just fine. The sophomore inwardly hissed when she brought an alcohol soaked cotton swab down on his open wound, but the pain subsided with the ointment, then tight dressing. She assessed his jaw quickly, asking if there was anything uncomfortable in his mouth before dismissing it as a harmless bruise which would come later.

While his nurse disappeared around the corner to fill out some paperwork, Ciel flopped back, his head hitting the stationary pillow with a small whoosh. Closing his eyes and counting the number of times his arm throbbed in the tight binding, Ciel wondered how Sebastian would take his new injuries.

He missed his boyfriend so much. Sure, they sometimes passed one another in the hallways – Victoria High was hardly a bustling urban school – but Ciel couldn't do much. He supposed it was his own fault, being too afraid to let anyone know of their relationship. His mother didn't know, and Ciel had half a mind to think Sebastian's parents had been left in the dark as well.

A week was nothing. Ciel had gone a whole month without seeing Sebastian before. Yet Ciel couldn't deny the fact he had fallen and scraped his knees. Battered not only on the outside, Sebastian had been the one who offered him a hand.

Needless to say, he had taken it and held tight.

Sebastian had kept his mouth shut all Saturday, forcing himself to accept that Ciel was alright despite the black and blue colored bruise spread along his jaw. But as they lounged on his couch, half listening to a movie in the dark, Sebastian found his fingers wandering down from gently petting his boyfriend's silky hair back to lightly tracing the firm yet discolored skin.

Ciel didn't seem to mind, appearing from Sebastian's view to be nearly half asleep by the way his eyes drooped. So Sebastian continued his gentle caressing, tracing the jaw and down Ciel's neck, content to feel his boyfriend's heart and relaxed breathing against his own.

"Can you tell me where you got this one?" The words flew from his mouth in a quiet murmur, his hand already back up and tracing the damage. If he hadn't known Ciel any better, he would have missed the small tension which gripped the smaller body.

The television continued to fill the silence between them as Ciel refused to say anything. Sebastian sighed, deciding to press the issue.

This caused Ciel to turn into the couch, more or less smashing his face against Sebastian's left arm. "Just drop it – I'm fine," came the tired answer.

Bending himself forward and hugging his boyfriend close as he buried his nose in Ciel's hair, Sebastian whispered, "I just want to help, baby." He pressed a kiss to the exposed temple and felt Ciel relax.

Reluctantly sitting back against the armrest meant he had done as Ciel asked. Sebastian didn't like it, but he didn't want to push Ciel. His boyfriend had already opened up so much to him in so little time, so he couldn't possibly ask for more. He would have to bite his tongue a little longer.

Sebastian quit holding his attention to the movie Ciel had turned back around to watch. Instead he thought, wrapping his arms around Ciel protectively.

Sometimes he felt as if he were in love with a butterfly. They were lovely, light and graceful, and so vibrant with color and beauty. But Sebastian had learnt that even the most beautiful butterflies had many weaknesses. They were so fragile, so easily damaged by the wind which helped them soar high in the sky. A simple rain could wash them of all color. It didn't matter how tough his Ciel acted on the outside, Sebastian knew what lay underneath.

Sebastian had resolved to protect and nurture his little blue butterfly, even if it were he who would end up hurt.

Ciel had fallen asleep long before the credits rolled up the screen. Curled up with his head pillowed by Sebastian's stomach, Sebastian flicked off the television before gathering up his slumbering boyfriend and heading to the bedroom for a comfortable night's sleep.
