Ryou was gazing into space as Professor Trelawney ranted on and on about how they were all doomed to die. She was using very odd words Ryou couldn't understand like "muggle" and "you-know-who." He'd long ago given up on understanding the teacher.

'What the hell is this lady talking about?' 'Kura? Why can't you be here?
(That can be arranged.)
Bakura pulled through the ring and ended up in front of Ryou who was pulling at the slightly uncomfortable clothes Bakura had put on him to help him blend into the class beforehand.
'Kura! Not like that! I meant: Why can't you be here to learn?
Bakura's soul voice chuckled through the mind link. (I can teach you something if you want.) The soul voice whispered seductively. Bakura then promptly sat on top of the desk pushing aside everything on there, 'who cares about a smashed glass ball anyway' He thought distractedly, and after all he had a Ryou to corrupt.
'Kura! What the- Ryou was silenced by Bakura placing, more like savaging, his lips on Ryou's. But we're in class... and the teacher...
Bakura sent a glare at the teacher and used some of his shadow magic to send her to the shadow realm while making it look like she was asleep, rather oddly though. (Happy?) Bakura purred biting on Ryou's bottom lip, causing Ryou to moan. 'Kura...
(Come into the soul room.) Bakura's soul voice hissed as Ryou bit Bakura's tongue that had just started to ravage his mouth. (Oh you're just daring me to take you in front of them, now.)
Ryou eeped unsure as to whether he was annoyed, he was still trying to learn, or happy that Bakura had found something that was more entertaining. Bakura pounced on him more, if that was even possible.

"Harry? What's that strange guy doing to- that other strange guy?" Hermione asked, she'd clearly had enough of divination and had glanced around the room finding some white haired man in a very suggestive pose on another white haired boy.
"Huh?" Harry answered her with another one of his most genius answers to her questions. Turning to look he was stopped as Hermione covered his eyes with her hand. "Umm, Hermione... I can't tell you what's happening if I can't see." He said pointing out the obvious.
"Sorry Harry but I just realised you might become, uh, weird if you see this."
"Huh?" His genius answer came again.
"Whoa! Harry, check out the two guys at the corner table!" Ron whispered rather loudly causing everyone to turn and see. This started many whispered conversations that were unnoticed by the divination teacher who seemed to be sleeping rather oddly.
Harry quickly pushed Hermione's hand away from his eyes and stared in shock at that white haired guy. That was the guy that was in his compartment on the train who left unexpectedly. Then again they did have a white haired guy in their class. "Umm, they look really similar and I thought we only had one weird white haired guy in our class." Hermione sighed, another intelligent conversation to be had...

"Harry. For the last time, Professor Trelawney is not a guy." Hermione said, rolling her eyes.

Harry just thought Hermione was loathing admitting she was wrong, and who could really tell if their teacher was indeed a woman. "Sorry Hermione, but I don't check out the professor as much as you so I wouldn't know." Harry grinned at the glare sent his way.

"'Kura?'" Ryou muttered into Bakura's mouth.
"Mmm?" Bakura replied still very determined to get some action.
"I think the whole class is watching us." Ryou said attempting to get away by scooting off the chair. This however worked to Bakura's favour as he sprung on top of Ryou and successfully placed Ryou's hands above his head with one hand. Ignoring Ryou's half-hearted protests, he kissed him dizzyingly and set to work on unbuttoning Ryou's pants. 'Thank god for these easy access robes' Bakura smirked, glad he had turned Ryou's clothes more like the ones the class were wearing.
"'Kura!" Ryou struggled, whispering fiercely. "The whole class IS watching, look."
Bakura grudgingly looked up at the class and saw many shocked faces staring with curiosity, he smirked. "What? Never seen someone molested in public?"
"Umm, 'Kura?" Ryou said distractedly, Bakura's hand never did stop its wandering. This being another reaction Bakura loved to cause in his hikari making Bakura grin at Ryou's glazed eyes. "Technically we're in class still... so, can we go to the soul room or you might as well send everyone to the shadow realm or I'll die of embarrassment." When Bakura smirked thinking over option two. Ryou turned his puppy eyes on him. "'Kura?" Bakura turned back to face Ryou, curious as to what would make his light sound so cute. "You know... it'll take a lot longer to banish them all to the shadow realm than just us going to the soul room." Ryou said somewhat innocently, rubbing one leg against Bakura, causing his eyes to glaze lustfully. "Well, see you soon, I hope." Ryou whispered before disappearing into the soul room, meanwhile making his body faint.
"Ryou..." Bakura moaned, disappointed to lose a chance to send people to the shadow realm but following after Ryou anyway.

The class looked on as the strange occurrence unfolded. "What the hell was that?" Harry asked, first to recover. "His whole body disappeared and the first guy fainted."
"Well my guess is that they're both in that "soul room" and doing pretty much what they were doing in here minus us staring." Hermione said in a single breath confidently yet still seeing if Harry would react.
"So... do we just leave him there?" Ron asked, "I mean he'll come 'round, eventually."
"Uhh, why is our teacher asleep?" Someone asked.
'Yay,' Harry thought, 'something has happened so we can get out of another class!' "I think we should take them to the infirmary since they're looking a little dead." He said, trying to contain his glee.
"No... It's more like they aren't in there... like their souls are somewhere else." Hermione pondered.
"Plus we can get a free class time since this was so 'traumatic' for us. Hey let's play it up a lot." Harry added.
"Like how, we can't play it up by saying they were going at it... because they WERE!" Someone said.
"Hmm... Let's say, hmm, someone died is not it. How about: someone took over our teacher and tried to kill us so we can never come back to this class again and we should have free time instead." Harry said, happy for an excuse.
"That might work..." Ron said thinking hard.
"But missing class..." Hermione hesitated.
"You hate this class." Harry pointed out.
"Well... let's get them to the hospital wing first." Hermione smiled.
Harry and Ron whooped. The class looked confused but decided to go along with it if it meant no more Divination.

Bakura became aware of something wrong with his hikari's body, it felt like a tug on his actual body. Bakura pulled out of the soul room and into his own body, his dark aura menacing. He figured he'd need to protect his angel with a body this time, and he could as well disturb Ryou whenever he was done. He'd been trying to find a plan which involved him being a hero for Ryou, for a while now.
"What the hell are you doing to my hikari?" Bakura demanded, seeing some nurse putting Ryou down on a bed. "Only I'm allowed to do that!" He roared.
Ryou sat up groggily, "Why'd you leave, Bakura?" Ryou asked rubbing his eyes and not yet knowing others were in the room. "Usually you insist that you make me yours more than 4 times..." Ryou trailed off as he noticed others in the room, namely the nurse, Harry, Ron and Hermione. "Oh my Ra!" Ryou said falling back into the pillows behind him.
"Ryou!" Bakura lunged towards the other boy, latching onto him protectively and glaring at anyone too close.
"It's all right, 'Kura." Ryou whispered, "Head rush. You know I get tired after you-" Ryou stopped himself as Bakura grinned nipping his ear playfully.
"Why, angel baby, I thought you liked it rough."
"... That's you, Bakura. All you." Bakura chuckled at Ryou's remark.
"I don't hear you complaining, too much. More like moaning." Bakura thought suddenly, head in the events of the soul room moments ago.
"When'd you get into the school anyway, I was sleeping. Happily, I might add." Ryou asked upon sitting up and gazing at Bakura, the two completely oblivious to the others in the room. Even Dumbledore had come in to see what kept Harry from class but was shocked into silence to what was happening.
"After you entered the soul room, seeing the spider, remember? This place is too dangerous to leave you alone, hikari-koi." He explained.
"Aww, Yamiii." Ryou smiled charmingly, earning a kiss from Bakura. He then picked Ryou up bridal style, only then noticing the crowd. "What?" He asked darkly. Ryou shushed him.
"Hello." Ryou said politely to everyone gathered, a slight pink tinge to his cheeks.

A/N: Ok, I forgot to mention a few things. For those confused about the random Japanese I put in. here:

hikari – light (what Bakura calls Ryou)
koi – request/ tender loving (just a cute way of a question mark that makes it clear it is a request and also it is said lovingly.) Also it is a shortened form of "koibito" which means sweetheart or lover.
yami – dark (what Ryou calls Bakura)

If I left something out then ask in the reviews and I'll try add it in the next one.

Also, I wrote the middle beforehand so I can update really quickly now. Any suggestions can be incorporated into the story though if anyone wants something in particular.

Also, again, who wants a side pairing of Harry x Draco? =D
