a/n: another abrupt and stupid ending from yours truly D: thank you for following to the end if you did, and I hope I didn't disappoint although I'm sure I have. Feel free to point out heinous errors, or if you have a better grasp of the English language than I do, I could use a beta ;_;

After changing out of her sticky shorts and into a pair that would hopefully remain clean for the rest of the day, Sungmin found herself standing in Kyuhyun's doorway, curling her fingers tightly around the strap of her purse, holding the large leather bag in front of her with both hands, staring at his dozing figure. It looked to her like he hadn't moved much at all since she'd gone to clean up and talked to Heechul; his jeans were still resting low on his hips, and with the way his body was stretched out, slightly twisted, it showed his knobby hip bones in prominent relief. Sungmin's fingers itched to trickle over them delicately like water droplets, so she gripped her bag tighter. She bit her lip, thinking she shouldn't wake him up, but she didn't really want to leave without saying something. Anything.
Kyuhyun's body was rather frail. He had minute lean muscle, and ironically probably had more during the semesters when he was busy attending classes, but if he really gamed all day long in the summer like Heechul had said, he'd probably gotten thinner over the recent weeks. Sungmin could see his concave stomach, his skin stretched over his ribs - he'd probably worn himself out just from rutting against her. Sungmin's thighs burned at the memory and she sighed weakly, rubbing a tired hand down her face before stepping back into the room.
When she reached Kyuhyun's bed she sat gingerly down on the edge of his mattress, beside his hip, and ever so carefully let her fingers give into the desire to feel his skin. He was remarkably pale, even more so than Heechul, and as she ghosted her fingertips near his navel she wondered if it was due to gaming inside all day, or just genetics.
"What're you doing?" Kyuhyun mumbled suddenly, catching her off guard. She snapped her eyes from the thin path of dark hair leading below his waistband to his face, and saw him looking at her with a sleepy smirk on his face. Sungmin pouted; only Kyuhyun could smirk sleepily.
"Playing," she teased, poking her fingertip into his navel, causing him to jerk and grab her wrist. When he started to pull her down on top of him, she shook her head and pulled her arm away, watching his eyes widen and his lower lip push out. "No," she scolded, tapping his nose before giving in enough to thread her fingers through his messy hair. "I need to get home; Heechul-ah woke up for a bit... she seemed better, but still tired. I would stay and help but I think I've overstayed my welcome," she murmured wryly, brushing her fingertips down behind Kyuhyun's ear, watching him shiver and close his eyes briefly. "And I have to be at a class downtown by five, so-"
"But it's summer," Kyuhyun interrupted, reaching his other arm around her waist, pulling at her impatiently.
"It's not for university credit," Sungmin murmured a bit moodily. She drew herself up onto the bed and buried her face in Kyuhyun's neck; he smelled like he would taste good, but Sungmin knew if she lapped her tongue against his warm skin she would never leave this house or make it to her dance class on time.
"What does that mean?" Kyuhyun wondered aloud, pulling her thigh up over his hip, wrapping himself in her warmth.
"Nothing interesting," Sungmin dismissed breezily, leaning back to peck Kyuhyun quickly on the lips, before slipping out of his grasp like sand. Kyuhyun balked, scrambling clumsily after her as she climbed off the bed.
"Wait - what - where are you going? You're really leaving?" He asked incredulously. He'd pushed himself onto his knees and rested some of his weight on his hands between his spread thighs, leaning toward her slightly like an eager dog. "I don't even..." he trailed off, looking lost among his own thoughts.
Sungmin stopped abruptly when she caught sight of how abandoned and devastated he looked. Heechul's little brother... Kyuhyun - everything came barreling back down on her in an instant. She'd only met this boy last night and yet it had seemed like days; and yet it had seemed like she'd known him forever, because she could trust him; and yet it had seemed like they were lovers, because she slept beside him, and he'd grabbed her breasts like it was okay, and they'd come together and Heechul was her best friend, and Kyuhyun's sister, just in the other room-
"Don't even what?" She voiced hesitantly, pulling her purse onto her shoulder.
Kyuhyun was staring at her with a dumbfounded expression on his face. Sungmin brushed at her nose self-consciously and crossed her arms over her stomach.
"Don't even know anything about you," he finished with a shrug, slumping back down onto his bed, dejected.
Sungmin smiled shyly, a blush coloring her cheeks as she bit her lower lip. At this point, after the few hours they'd known each other thus far, she was almost willing to bet that Kyuhyun knew her better than anyone else - even Heechul. But she wasn't going to tell him that.
"I'm Sungmin," she said simply, and Kyuhyun growled, swiping his arm out suddenly to catch her belt loop with a slender finger. He tugged her back up against the bed and wrapped both arms around her waist, pulling her close.
"Funny," he huffed, pressing his lips to hers needily. Sungmin indulged him for several long minutes, cupping his face in her hands as they both learned together how to breathe through their noses to prolong the contact. Kyuhyun's hands wandered everywhere, into places she wouldn't have dreamed of being touched, but she was starting to realize that with Kyuhyun nothing should come as a surprise. His hands were like curious little children, learning by trial and error. Sungmin wondered if she were to slap his fingers when they touched something forbidden, would he learn to behave, or was it a lost cause? She supposed it didn't really matter, though; she had no intention of stopping him anytime soon.
They were both beginners at this sort of thing, it seemed - without any realistic models to follow other than late night dramas that Sungmin didn't have time to watch because of her studies, and that Kyuhyun probably had no interest in watching because of his games. Sungmin instead relied solely on what she wanted, and what felt good. She smoothed her palms over his imperfect skin, feeling stubble along the contours of his jaw; she brushed the tips of her fingers over his ear lobes and behind, causing his body to tremble against her reflexively; she buried her fingers deep into his thick brown hair and let her other hand wander down his bare chest, selfishly enjoying the smooth skin and the groan Kyuhyun released into her mouth when her pinky brushed an erect nipple.
When they finally did part, gasping for air, Kyuhyun wheezed and crumpled over on her slightly. Sungmin huffed breathlessly and grabbed his arms, pushing him back to see his neck lolling and his eyes heavy-lidded.
"Kyuhyun-ah," she inhaled sharply, cupping his face with a cool palm. "When was the last time you ate?" She asked frantically, maneuvering him back onto the bed as gently as possible. His lanky body melted into the mess of blankets and Sungmin pressed her palm shakily to his sunken stomach.
"I had coffee," Kyuhyun murmured sleepily, placing his hand over Sungmin's.
"For God's sake," she sighed dramatically. "That isn't food, Kyuhyun-ah!" Sungmin let her bag fall with a heavy 'thunk' onto the floor and she reached out with her free hand to dim his bedside lamp. When she looked back, Kyuhyun's eyes were fluttering weakly as he tried to lace their fingers together. Sungmin bit her lip and reached up to brush some fringe off his warm forehead, sighing quietly when his dark eyelashes continued to flutter. "You're going to be such a handful," she murmured to herself, already imagining how Shindong would lecture her for being late and Donghae would whine about not having his favorite dance partner. This class was important to her, especially because she wasn't allowed to study what she truly wanted during the semester, but seeing Kyuhyun so weak, knowing he either wouldn't take care of himself or wouldn't be able to take care of himself... Sungmin leaned over, pressed her lips to the shell of his ear, and asked quietly, "Kyu, what's your favorite thing to eat?"
"Mmm, jeongol... haemul jeongol," he replied tiredly albeit without hesitation, and Sungmin laughed weakly.
"Bibimbap it is, then," she promised, and kissed his cheekbone gently. He whined and tried to cling to her, but she managed to disentangle herself with a huff. "It won't take long, I promise. Just rest for now, okay?"
Sungmin watched Kyuhyun grumble unintelligibly and curl onto his side, his brow furrowed and lips slightly pursed. She spared a bit of energy to marvel at the irony of where her motherly instincts could have possibly come from as she pulled his blankets up and tucked his half-naked body into a warm cocoon, but when he shivered and whined, clutching his stomach, she cleared her head and hurried off to the kitchen, already making a mental check-list of the things she hoped could be found in the refrigerator so she could make a healthy dinner for both Kyuhyun and Heechul.
Heechul watched from beyond Kyuhyun's partially open bedroom door as her younger brother was fed with chopsticks by her best friend. It was a repulsive sight, she decided; Kyuhyun was positively spoiled. He was propped up by a make-shift throne of comfortable-looking pillows, reclining like a king, with his little concubine on his lap, feeding him what looked like a duplicate of the bowl she clutched in her own hands - the bowl that Sungmin had set on her bedside table before pressing a kiss to her temple and trying to coax her awake - as he fondled and rubbed and groped at Sungmin's thighs and backside.
Ugh. How in the hell that perverted little shit had found someone before her, she would never understand, or why it had to be Sungmin of all the innocent, virginal people in the world. She munched moodily but quietly and leaned heavily against the wall outside Kyuhyun's bedroom, watching as Sungmin brought carrots, bean sprouts, and rice up to Kyuhyun's mouth. The younger boy happily devoured it and promptly opened his mouth again for more. Heechul dug around grumpily in her own bowl, wondering why eating bibimbap had never been such a sexy experience for her.
"You're like a pig," Sungmin teased cutely, and Heechul mimicked her snottily under her breath, looking up to see Kyuhyun snap his teeth at her and snort, causing Sungmin to burst into a breathless round of laughter and spill bits of rice and mushroom onto Kyuhyun's bare chest.
"No," Kyuhyun stopped her when she moved to pick up the bits with her fingers, capturing her hand with his own. Heechul watched with a brow raised as the two stared at each other for a moment. Kyuhyun didn't say anything further, just stared at Sungmin in a way that Heechul didn't quite understand, that had her ready to whine 'yah, what are you two doing?' until Sungmin slowly bowed her head and pressed her lips to Kyuhyun's bare chest. When she came back up, a mushroom was gone and she was licking her lips.
Heechul's mouth fell open, half-chewed rice spilling back into her bowl in shock as she watched Sungmin proceed to clean up the food from Kyuhyun's chest by trailing her lips along his skin, tongue darting out now and then. Kyuhyun whimpered - actually whimpered - and the whole scene was just too disgusting for Heechul to watch any longer. She shuffled off down the hall, gnashing her teeth on a defenseless mushroom, trying to rid her mind of the image of Sungmin behaving less than innocently and her grotesque little brother making noises she would rather not have ever, ever, ever heard.
