Okay, okay. Sorry it took so long. I need to focus on school work, drama, and speech. I'm doing a speech on the battle between the Olypians and the Titans. Did you know that Cronos used to eat his children? Well you do now. Anyways on with the slash-y-ness.

Remus was beginning to get worried. Sirius was now ten minutes late for their detention, but nothing could've prepared him for when Sirius walk through the door.

"Sorry I'm late professor." Sirius said.

But neither Professor Slughorn nor Remus could speak. Their stood Sirius with the world's most innocent expression on his face while wearing a Gryffindor girl's school uniform.

"M-Mr. Black, What is the meaning of this." Slughorn asked.

"Well sir, I lost a bet. So I have to wear this outfit for the rest of the night." Sirius explained. He twirled on of his pigtails with his fingers, then tighten the red ribbon that held it back.

Remus' eyes traveled over Sirius' body. Sirius noticed this and gave him a playful wink.

"Well, then I guess I can let it slide. Well gentlemen, I have some pressing matters to attend to. So I'm afraid I must leave you. The door will be locked, but it will unlock in exactly one hour."

And with that Professor Slughorn hurried out of the room.

"Does he always do this?" Remus asked.

"Every time." Sirius smiled.

"Do you always show up dressed like this?" He asked raising an eye brow.

"Only on special occations."

"So this really wasn't for a bet, this is for," Remus swallowed hard and flushed, "me." He finished.

"Of course." Sirius said. "I have a very special task for you."

"I don't know Siri, my bum kinda hurts." Remus said.

"That's the beauty in it. You'll be fucking me." He said.

Remus' eyes widened. He had never at all had toped. Not once in the entire year he had been dating Sirius, or anyone else for that matter.

"Okay."

"Here the deal. You are going to pretend to be a Professor and I am going to be a school girl willing to do anything to bring her grade up."

"I can do that."

Remus sat down in Slughorn's desk.

Sirius cleared his throat.

"Professor, I would like to discus the grade I received on my last essay." Sirius said in a rather feminine voice.

"What would you like to discus about it?" Remus said, using what James and Sirius called his "Prefect voice" It made him sound much more adult.

"Well, my grade wasn't as high as I would like it to be, and my parents will be awful mad if they see it." Sirius said.

"All I can tell you is study harder next time."

"Please Professor." Sirius was in front of the desk now. "I'll do anything."

"Anything is a very powerful word."

"I mean it. I'll do anything."

And with that, Sirius leaned over the desk and kissed Remus. Remus stood up out of his chair and walked over to Sirius.

He pushed Sirius up onto the desk and he wrapped his legs around Remus' waist.

Remus ran his hands up Sirius' skirt and felled silky knickers underneath. Remus pulled back, a bit surprised that Sirius had taken it that far. Sirius blushed and gave Remus a small smiled.

Remus pulled the knickers off and tossed them aside before proceeding to take off his own clothes. Sirius did the same but Remus stopped his as he went to remove his skirt.

"Leave the skirt on." Remus commanded. Sirius nodded, incredibly turned on by the fact Remus liked the skirt.

"Bend over the desk." Remus told him. Sirius did as he was told.

He heard Remus cast a lubrication charm with his wand, which Slughorn hadn't bothered to take. Sirius felt his entrance slick up. The lube was cold, and he felt a bit funny, but those feeling went away as Remus began to edge in.

"Oh please Professor. More." Sirius begged.

Remus pushed completely into Sirius, finding his prostate immediately.

Sirius moaned loudly, never having felt anything so wonderful.

"Harder, faster, please."

Remus wasn't sure if he was doing it right, but Sirius seemed to like it.

He awkwardly thrusted into the bundle of nerves. Sirius moaned and bucked his hips beneath him. Soon both he and Remus were coming.

"That was bloody amazing." Sirius said as Remus pulled out of him. "I mean, if I thought fucking you was wonderful, getting fucked by you is just as mind blowing."

Remus simply smiled. "I think I might be able to raise your grade." He said, before kissing Sirius and gathering his clothes.

About 30 minutes later the door unlocked and they left.

Later that night after the others were asleep Sirius crawled into the bed with Remus.

"Not tonight Sirius, 'M tired." Remus said turning around as to not face his boyfriend.

"I'm not here for the Remy. I have bad news." Sirius said.

"What?" Remus asked.

"I left my knickers in the classroom."
