DearS: Fine Wine

Second Contact
"Time to wake up, Mistress."
Yuki ran a hand over her face as she tried to process what she'd just heard. Had she left the television on? No, she'd turned it off before she had even went to sleep. So what could that voice have been? Was the neighbor a peeping tom, looking in her window? Worried, she tried to sit up in her bed-
only to fall out of the couch, landing painfully on her rear. As she exclaimed in pain, she remembered why she was on her couch, but still hadn't found the source of the voice. She saw Ren looking down at her, naked again, and quickly looked away. Hasn't she figured out she's supposed to keep her clothes on? thought Yuki, as she got to her feet.
"It is getting late, you should leave for school shortly, Mistress."
There it was again! Yuki looked around, but the only source of the sound could have been... Ren? Dubiously, she looked at the girl curiously, wondering how she had learned to talk so well, especially over just one night. Were all DearS that gifted? Even so, it was kind of unreal, and Yuki collapsed back onto the couch.
"Mistress, what is wrong?"
Ren bent over to look at Yuki's face more clearly, but only succeeded in showing off her assets, as they seemed even larger when she bent over like that. Yuki turned her head away, wondering why she kept noticing Ren's endowments.
"I'm fine, it's nothing. But why are you calling me Mistress? My name's Yuki!"
Ren seemed to ponder the matter for a moment, then straightened up and smiled mysteriously.
"Mistress is Mistress."
Yuki sighed when she heard this; could things get any more weird? Just then, she heard a familiar chime; that was the school bell! She was going to be late! She ran into her room, and various pieces of clothing flew through the air as she hurriedly got dressed and grabbed her bag. With all the commotion that'd been happening lately, she hadn't even finished her homework the night before.
She ran out of the house without even bothering to grab anything for breakfast, and was gone. Ren watched her go, and a loud rumble filled the room as it soon became obvious she was hungry.
It couldn't have gone any worse. Of course, today was the day that Yuki got called on to solve most of the problems from the previous night's assignment, and then there was a pop quiz, and then she realized she'd forgotten her coinpurse at home so she couldn't afford anything for lunch.
Leaning her head down to stare at her desk, Yuki tried to ignore the feeling in the pit of her stomach as her body complained about the lack of food. Just then, a small commotion reached her ears from outside. Curious, and eager to find a diversion from her own predicament, Yuki went to the window and looked down at the gate to see what was going on.
"Ren-chan! What's she doing here?!"
Ren was standing at the gate, luckily wearing clothes. Unfortunately those clothes were that fetish suit she had in her collar, which meant that there was a growing crowd of boys swarming her. Forgetting her hunger, Yuki ran out of the classroom, down the stairs, and out of the school.
Coming to a stop near the crowd, she tried to squeeze past the throng, but they were having none of it. She walked along it's edge, trying to find a way to get closer to Ren, to see why in the world she'd come here, or rather, how in the world she had known to come here.
"Ren-chan! Meet me on the roof!"
She couldn't think of any other ideas, and just hoped Ren would be able to get there on her own. Turning, Yuki dashed back to the school, and ran headlong towards the the stairs and roof, the crowd of boys hot on her heels. She just barely kept ahead of them, and tore open the door before slamming it shut behind her. Leaning against it, she felt the muffled thumps as the boys tried to force their way past her. Where was Ren? It wasn't like she could get to the roof any other way, she must not have been able to manage it.
"Mistress?"
Yuki looked up, surprised. Ren stood a short distance away, balanced somehow on the flimsy chain link fence surrounding the roof. Yuki didn't dare move closer, the thuds at the door were only increasing, and she could barely hold them back any longer. She motioned for Ren to come closer, and watched as Ren leapt nimbly through the air, landing right in front of her.
Blinking, Yuki needed a moment to catch her train of thought. Then she remembered, and stabbed a finger at Ren.
"What are you doing here? You were supposed to stay at home! And don't go outside in that outfit, it's not decent!"
Stopping to catch her breath, Yuki waited to hear Ren reply. She hoped it would be an agreement, but it wasn't.
"I can't do that, Mistress. You forgot this."
Ren held up a small lime-green pouch, it was Yuki's coin purse. Yuki's eyes widened, was that why she had come to school after her?
"Th-thank you, Ren-chan. But you should head home now."
The last half of what she had been saying was lost on Ren, as her stomach gurgled loudly. Of course, Yuki though. She probably hadn't had anything to eat this morning either. She had enough money for two lunches, and she couldn't send Ren away hungry after she'd gone through the trouble to bring her coinpurse, could she? Yuki sighed, and tried to think of a solution. Ren couldn't go around school like that, it attracted too much attention. Yuki already had physical education, so her gym clothes were in her bag back in her classroom. They were a little dirty, but better than nothing.
"Okay, Ren-chan? Wait for me behind the school, I'll get there as soon as I can."
"Yes, Mistress."
At that, Ren did a backflip and cleared the chain link fence, disappearing over the edge. Forgetting about the crowd of boys at the door, Yuki dashed to the edge of the roof and looked down, but Ren was nowhere to be seen. Just then, the door slammed open, and the throng swarmed out, looking for Ren. Of course, she wasn't there any more, but they didn't know that and kept looking. Yuki took this as an opportunity to slip past them and head back to the classroom. Entering, she grabbed up her bag and left again, ignoring her friend's call to eat lunch together in her hurry. Heading towards the school's doors, she left and went around the back, staying close to the building to hopefully attract less attention.
The back of the school was just as she'd hoped, empty. There weren't very many windows on this side of the building, so she felt fairly sure nobody would notice them, at least if they hurried. But where was Ren? Looking around, she couldn't see her anywhere. Had she went to the wrong side of the building? No, this was the back of the school, it was obviously the right side. So where was she?
"Ren-chan?"
"Yes, Mistress?"
Yuki whirled in surprise as she felt more than heard Ren's words, her face a bright red. Ren had whispered right in her ear, her warm breath tickling the side of her neck. Yuki tried to calm herself down, her heart racing, and not just from the surprise. She felt her cheeks burning, and only with a supreme effort of will was she able to calm herself down to the point she could talk clearly. Rummaging through her bag, she found her gym clothes and socks and shoes, and hoped it would be good enough. Holding them out to Ren, she looked around to make sure nobody knew they were there. It would have been better to change in the bathroom or something, but Ren wouldn't make it through the school unseen, not dressed as she was now.
"Here, change into these."
"Yes, Mistress."
Ren took the proferred garments and tapped the metal link on her collar, making her fetish suit disappear and leaving her buck naked. Yuki was caught by surprise and whirled around, blushing once more, as she stood lookout. She told Ren to hurry up and get dressed, and waited as long as she could before taking another peek. Predictably, Ren hadn't known how to put the clothes on, and still stood there naked. Sighing, Yuki helped dress her, and only then realized the sheer difference in their dimensions. The shorts went on with just a little trouble, they were very snug and rode up Ren's butt just a little, showing off her well-toned buttocks. The top was another matter. It had been slightly loose on Yuki, but with Ren's tremendous breasts it was downright tight. It didn't even reach down to cover her entire midriff, and barely had enough give to stretch around her torso. As it was, her breasts were sharply defined, slight bumps indicating her nipples' presence as well. The socks and shoes went on easy enough, and then it was done.
The overly small clothes only made her sexier! Yuki sighed, but there was nothing she could do about it now, she'd have to get them both to the cafeteria and eat, then get Ren home as fast as possible. Hopefully most of the boys would be on the lookout for a girl in that fetish suit, instead of very tight gym clothes. Even so, she wasn't naive enough to think that nobody would notice a chest like that, bobbling merrily along as she walked. Yuki herself was nearly mesmerized by the twin jiggling as she led Ren back towards the school's entrance.
Blushing again, she berated herself at getting so heated up over another girl. Sure Ren was pretty, but come on! This was getting out of hand! What was wrong with her? Unless it was something about the DearS as a whole? She'd never met one before, maybe they had amazingly powerful pheremones or sexy brain waves or something? That must be it, she'd just have to try to stay focused, not notice those long, smooth legs, that perfect skin, those pert lips... No, it was happening again!
Just then, Ren stopped, her breasts taking a moment longer than her to do the same. Yuki turned around to see what was the matter, and stepped back instinctively as Ren approached, an expression in her eyes that made Yuki very nervous. It almost looked like... desire?
"Ren-chan, wh-what are you doing?"
"I sense you are physically hungry, Mistress. I will appease your desire."
Before Yuki had a chance to say anything, Ren was already there, her lips reaching out and touching Yuki's. It was so soft, Yuki's mind went blank for an instant, and everything went to a soft, warm light.
When she woke up, Yuki looked around confusedly, then saw Ren sitting down next to her against the school's wall. Without warning, the memories of that kiss swept back to her, making her blush even deeper than before. Why had that happened? And why had it felt so good?! That had been her first kiss, too! She put a hand to her lips, feeling a little betrayed and sad. Ren had stolen her first kiss, she had wanted it to be special! It wasn't fair!
All thoughts of lunch gone from her mind, Yuki teared up and ran off the school grounds, headed home. She didn't care that she would miss the second half of school that day, or what happened to Ren. She just wanted to be at home in her bed and cry.
Ren watched as Yuki began to cry and run away, and gingerly stretched out a hand to try to stop her. But it was too late, she was already gone. Letting her arm drop to her side, she watched Yuki's shadow until long after it had stopped being visible.
"Mistress..."
