His Favourite Thoughts

Warnings for implied smut. This is a very high T rated fic.

Sirius forced up the barriers in his mind as he felt someone search his mind for the first time during training. He was proud of himself: having more barriers than anyone else, though it wasn't something to really be that proud of.

Keeping his family out of his head was imperative.

Moody withdrew for a moment, turning as though he was going to attempt the attack on Remus, who waited nearby. Suddenly he spun back, going straight back into Sirius' mind.

This time he was too quick for Sirius. Sirius hadn't been expecting the attack and with the walls down, Moody had a front row seat to the events that had transpired the previous evening, with his awkward stuttering as he asked both James and Remus to join him in bed for the first time.

"Constant vigilance," the older wizard barked, frowning at him. "The enemy isn't going to tell you when he's about to attack you. You have to learn to keep your walls up at all times!"

Sirius caught James' eye, and tried not to laugh. They had been all talking about the lessons they would be starting with Moody. Frank had already warned them that Moody's favourite past-time was delving into minds and learning secrets. The pair had been determined not to give anything away.

They both turned their attention to Remus, who looked like he was concentrating hard.

"What did he see?" James whispered.

"Your naked arse," Sirius shot back, causing the pair to giggle like children. Remus frowned at their laughter, and Moody took advantage of the momentary distraction to look into his mind.

The man quickly left Remus' mind, looking severely mortified at what he had seen. Sirius and James stopped laughing, wondering what could have caused the Auror—a man who had seen even the most grotesque murders—to react in such a way.

"What did you show him?" James whispered.

"Something that'll terrify him," Remus replied. Sirius and James looked at each other. Remus must have shown Moody his transformation, or the time he ate a rabbit.

"Whatever it is, it's big," Sirius said, decidedly.

...oOo...

Amber eyes looked up at the man who was running his long fingers through Remus' hair. An eager smirk crossed his lips. "Well? Are you going to suck or not?"

"Oh, you'll find I don't suck," Remus retorted, pulling at the star-print boxers, letting them fall to the man's feet.

...oOo...

Sirius and James had practised a lot. James had never needed the Occlumancy barriers before, but he was a fast learner and had almost caught up to Sirius in no time. After all, getting the barrier up was simple. Holding it against attacks, and keeping it up over time was a totally different story.

Moody pointed his wand at Sirius, then at James in quick succession, muttering about a slight improvement. He turned to Remus who looked focused, hitting him with the spell.

"Good shields," Moody noted.

"Top of the class once more, Remus?" Sirius teased. "You planning on being the favourite student again?"

Remus turned to glare at Sirius and Moody once more took advantage of the distraction. "Not good enough it seems," Moody commented, before quickly backing away. "Lesson over," he snapped, walking from the room.

"It must have been really horrific," James murmured. "Are you okay, Moony?"

"Fine," Remus replied.

...oOo...

Rough, calloused fingers ran over his hips, and a hand pressed down on his back, not hard, but hard enough to tell him where to go. "Yeah like that," James groaned, standing behind Remus, completely naked and enjoying the sight. "Sirius, you can look now."

Sirius lifted his head from where he had been staring at the floor. "Fuck, he's beautiful."

"Did I say give you permission talk?" James asked calmly.

"Sorry Sir," Sirius murmured, before going silent, his eyes moving over Remus quite eagerly.

"Do you want to prepare him for me? Go on then."

Sirius almost fell over in his haste to get up from the floor. "Thank you, Sir," he murmured, kneeling behind Remus. "You're going to enjoy this!" he whispered to Remus.

...oOo...

Moody hadn't even walked into the room before catching Sirius. He managed to keep the walls firmly up, even when Moody had caused an explosion against the far wall to distract him. James was hit with a hex first, before Moody tried to get into his mind, and then he turned to Remus.

There was a long hesitation. "Been working on your Occlumancy?"

"I have."

"Will the wall stay up this time?"

Remus nodded.

Eager to see what would happen, James and Sirius both flung a hex at Remus to distract him, as Moody pushed past the barrier into his mind.

...oOo...

/"Sirius, since I'm feeling generous, I'll let you choose which part of James you want."

Sirius walked around the bed, staring at the spread-out man who was watching them with wide eyes. "No more teasing," James begged. "Just please…"

Sirius stopped by James' legs, looking up at Remus.

"Good choice," Remus murmured. "So, James… if you want your reward, you're going to have to work for it."

"Of course," James whispered, trying to move closer to Remus, though his hands and legs were bound, not allowing much movement.

"And you remember the word if you want to stop?"

"Fuck off, like I'd even think about stopping now," James snapped. He jumped as hands ran over his hips. "Just hurry up, please!"

...oOo...

Moony pulled back, his eyes narrowing at Remus, who gazed, innocently back. "I think you all have Occlumancy mastered. Lupin, excellent technique in ensuring no-one would ever want to look into your mind. Potter, Black, keep practising holding the barriers as long as possible.

"So, are you ever going to tell us what he saw?" James and Sirius both asked, walking out of the room with Remus.

Remus laughed softly as he shook his head. "Enough to stop Moody from ever wanting to look into my mind again."
