Whoo, this took a while to write, so of course, here's
TWO CHAPTERS instead of one! And I promise, there will be some TaGaki and KameShige. Please bear with me.

WARNING: Bits of it are slightly graphic, so, watch out!
Chapter 3--continued right after Chapter 2--
"My batteries are charged." Eri pronounced, pinning Risa on the bed. Kamei winked at Niigaki. Nobody could cut sexual tension like Kamei Eri.
Laughing, Risa's attention refocused once again on Eri's brown eyes peering inquisitively down at her.
Different. Yes.
This is Kamei Eri, she thought and smiled. Her Kame-chan. She was here, now; her adorably awkward turtle.
All other thoughts vanished as she pulled Eri in for a kiss. Their mouths connected instantly. In an urgent and perhaps even slightly desperate move, Risa wrapped her arms tightly around Eri's back and deepened the kiss. She needed what Eri was more than willing to give her, and she couldn't help but hate herself a little for it. But no matter now.
She giggled into Eri's mouth when she felt the other nibbling her lips.
"Hungry?"
"I was trying to be sensual..." Eri huffed, unbuttoning Risa's thin shirt. Half-way through she got fed up and simply pulled the shirt over and off of Risa.
"Impatien-?" Niigaki's retort was silenced by Eri's cool touch mapping out her taut body. Kamei's hands knew all the familiar roads down to the best spots. Illiciting a small gasp, Risa bit her knuckles as Kamei kissed her way down.

"uu don wan any?" Koharu called to Sayumi, her mouth currently crammed with cake.
"It's really good!" Mitsui giggled, dabbing a bit of cream on Kusumi's nose. The two giggled and fussed over the feast of sweets set out in Sayu's room. "Michishige-san...?" Sayumi shook her head and shifted on her bed so that she faced the wall.
Aika and Koharu shared a knowing glance. Their senior was not to be disturbed, but they were obligated as friends to stay and keep her company. It was unpleasant knowing that they couldn't help ease Michishige's unhappiness, but anything they could do for her they would.
However, unbeknownst to the young pair, their presence was totally overlooked by Michishige at the moment. With her back facing her juniors, Sayumi laid perfectly still, her mind focused on only one thing.
"Eric..." her hands clutched at her aching chest as she drifted off into a dreamless slumber.

Good God she was tired. Ai laid on her bed, opening and closing her eyes. Open.
Nothing. Close.
Kamei sucking on Risa's smooth, unblemished neck. Open.
Nothing. Close.
Risa gasping and pushing Kamei's head to her chest and crying out "Er--Open.
Nothing. Close.
Eri licking the sweat droplets from around one of Risa's pert--Open.
Nothing.
"I'm so tired..." Takahashi groaned, covering her opened eyes with the palm of her hand.
*KNOCK* *KNOCK*
Ai uncovered her eyes.
"Delivery for Takahashi Ai," came a low, feminine voice at her door.
No one comes into the dorms to deliver packages. They leave it at the front desk, she thought. Ai sat up on her bed and stared at the closed door.
If a killer were to come in, there would be nowhere for me to escape. Takahashi was on the 3rd floor with no balcony. Her hands gripped tightly onto her bed spread. She couldn't help but jump to conclusions, especially since this day had been so screwed up and surreal already. Who's to say that she couldn't possibly get murdered as well? Yet the door handle did not turn and so no one entered. Instead, a small envelope was pushed under the door. "See you tonight," came the voice again.
Ai jumped to her feet, rushed over and swung the door open. But by then, the person was gone. Only the envelope remained as evidence that she wasn't a figment of Ai's imagination.
That voice sounded familiar...Ai contemplated, but couldn't place where she'd heard it before.
Deeming the matter pointless to dwell over at the moment, she shifted her focus back on the small, beige envelope. With her heart pounding in her throat, Ai steadied her nervous hand enough to unwind the twine around the clasp. Timidly, she reached her hand and and drew out a single photo.
Two linked arms. She recognized the sleeve of her shirt that she'd worn for the taping earlier in the day. The other arm was obviously Gaki-san's. Takahashi flipped the photo over. 'Nostalgic isn't it? Don't forget. Midnight,' said the note written on the back.
Ai tore the photo in two. Who was doing this?
She couldn't stay here. The photo, and everything it entailed...it was like a poison--one that poisoned her against Kamei Eri. It had reminded her of what she'd lost to Kame-chan. Ai felt repulsed of herself at the thought. After hurriedly slipping on a thin jacket, Ai grabbed her purse and left the dorms, taking care to look at the large clock by the frontdesk.
8:35 P.M.
*
Unconsciously, she had meandered over to a nearby bar. Ai didn't care much for alcohol, but she didn't want to stray too far from the H!P dorms either.
"Hello..." Ai called out as she entered the bar. Taking a moment to survey the place, Takahashi noted that atmosphere was rather low-key and the few patrons were mainly tired-looking businessmen calmly nursing their drinks. Immediately she felt a burden loosening from her shoulders.
"Hello!" the bartender greeted back. "Take a seat." Nodding her thanks, Ai quietly slipped onto a barstool and hung her head low as if to avoid detection.
"Ai-chan?" spoke a familiar voice. Takahashi immediately turned to face the speaker, and was wholly unsurprised at who it was.
"Nakazawa-san..."
"What are you doing here?"
"Same to you," Ai retorted, avoiding the question.
"Off work," came the nonchalant reply. "Come have a seat by me!" Yuko offered genially, patting the spot next to her. "Since when do you come to bars by yourself?" Ai shook her head, her mouth clamped shut. Taking the hint, Nakazawa nodded understandingly and poured Ai a cup of warm sake. "Calms the nerves."
Ai drank it in a gulp and slammed the glass on the bar counter, startling a few patrons. "Another," she demanded.
Yuko obliged and poured her another, then poured one for herself. It was always more fun to get smashed with another person anyway.

Eri was once again asleep, except this time they were both naked under the bedsheets. But when Kamei was off dreaming, Risa was left to her own thoughts. Clinging to Eri's slack, sleeping form, Niigaki wished desperately to believe that this was what she wanted. After all, what good was it to abandon all that she had to pursue something uncertain?
I'm content. I'm happy because Eri makes me so...but it wasn't the kind of happiness she was looking for and she knew it.
Looking at Eri's face, Risa repeated the mantra inwardly.
I'm content. I'm happy. She wiped the trail of drool from the corner of Eri's mouth. In turn, the sleeping Eri brushed her head against Risa's hand and smacked her lips.
Risa placed a gentle kiss on Eri's pink lips and settled back under the sheets. If she closed her eyes, she knew she'd only think of
her, and so she remained with her eyes open and stared up at the white ceiling.
"Gak.i..sa...n..." Risa turned her head. As usual, Kame-chan was sleep-talking.
So cute, she thought to herself.
"What is it, Kame-chan?" she soothed, softly rubbing Eri's cheek.
"...Do you know who ate my cheese...?" Risa smiled warmly at Eri.
"Ah...I thought you shared it with Koharu-chan yesterday?"
"Oh yeah...thath...righ..." Eri mumbled.
It killed Risa to do this to Eri. She wasn't worthy to be here, lying next to such sweet and gentle girl.
And to do this to a close friend...I'm the worst... What one's loneliness was capable of achieving--it frightened Risa.
Shutting her eyes tightly, Risa recited her mantra quietly, pleadingly, "I'm content...I'm happy..."

"Damn...they died down..." Miki whispered disappointedly.
"Miki, get your ear away from the wall," Ayaya warned. "What if they found out that you were listening in on them?"
"Oh please," Miki scoffed. Fujimoto Miki was not afraid of being caught. It's the people who catch her who have anything to fear. "Man Aya-chan, they were wild an hour ago!" Miki whispered loudly, leering at her best friend from her place against the wall. "All 'ah!' and 'oh!'" Ah, the perks of having one's room next to Kamei's, Miki smirked.
"MIKI!" Ayaya shouted angrily. Ayaya pulled her other ear and dragged an unhappy Miki from her dorm room.
"Owowowow!!!"

It was bed time. Koharu and Mitsui looked from the bed-side clock to their sempai. They had to get up early the next day to film their Chinese segment.
"Michishige-san..." Koharu nudged the sleeping girl.
"Mmm...Kirari-chan...?"
"It's already 11, so Aika and I are going to bed now. Goodnight!"
"Okay...goodnight," Sayumi murmured, waving at the pair as they exited her room.
After the two left, Sayumi got up and stretched her sore muscles. Sleeping in a ball left her with knotted muscles all over. "Oof..." she groaned, and fell back on her bed. But she couldn't go back to sleep yet.

"And...so...*hic* so I said...'Who's yo Mama, bi--otch...?!'"
"HaHAHahHAhA!" Ai screeched.
"Kei don't mess with me," Yuko proclaimed loudly while swinging a large bottle of sake every-which-way.
"Ladies," the bartender interrupted timidly. After hearing Yuko's story of how she nearly blew her friend's home to bits, he wasn't quite sure how to approach the pair. "Ladies, it's nearly twelve. Time to close shop, I'm afraid."
"WHAH?! WHAH YOU SAY TO ME?!" Yuko slurred.
"Whu, I-"
"YOU CALLIN' ME OLD?!"
"No, miss, I sa--Whoa--Wait--! Watch where you swing that bottle-!"
Ai sat laughing at the two, not noticing that she was slipping off the barstool. "Oof!"
"AI-CHAN. ARE YOU OK?" Yuko shouted.
"Ugh...yeah..." rubbing her head, Ai looked at her watch. 11:48. She scrambled to her feet, her head clearing slightly. Slamming some cash down, Takahashi dashed from the bar back to the dorms. Her legs felt weak and her vision was disoriented, but she pushed on, thinking only of the consequences of her tardiness. Both Kamei and Gaki-san would be ruined...

Fishing out her ID card, Ai swiped it through the checkpoint and dashed into the dorm building. She glanced at the large clock by the frontdesk as she ran for the stairs.
11:56.
Takahashi dashed up the several flights of stairs to the roof, adrenaline pumping in her veins.
If I don't get there in time...she shook her head. There wasn't time to contemplate the consequences now.
Level 2...3...she was sprinting now that strength was returning to her legs.
Gaki-san! She pulled open the heavy metal door and was hit by a strong gust of cool air. Shivering slightly, Takahashi haphazardly wiped the sweat from her brow and walked out onto the roof.

Sayumi.
