Remus could picture it in his mind when it was late at night. No matter where he was, whether it be the library, the common room, or on his bed, he couldn't get it out of his mind. What was this 'it'? Well... you could always ask Sirius.

Any time Sirius caught Remus spacing out, a smug little grin went across his face. He knew exactly what he was thinking about. Every time. Even the first time it happened, Sirius had guessed almost immediately what Remus was thinking, and teased the boy about it relentlessly.

Remus both wanted to strangle him and kiss him again.

Yes, again. The one thing Remus couldn't stop thinking about was a particular night with Sirius. The moment was intimate. Both trusting, and passionate. Yet, apart from the whole experience being perfect, one certain moment replayed in Remus's head.

They were kissing, their clothes half-hazardly thrown off. Each second sent tingles through both boys, yet when Sirius pulled back, he didn't waste time. Cupping Remus's jaw, Sirius tilted his head up against Remus's throat, his tongue darting out to lick a stripe up the warm skin. Remus's breath shuddered immediately, the feeling more exquisite than Remus's favorite chocolate. The moment grew fuzzy.

"You're doing it again."

A voice brought Remus out of his zoned out state, already knowing who the voice belonged to. He sent a certain look towards the long-haired boy, a flush covering his scarred cheeks. "Be quiet. I'm thinking about the Transfiguration test." Remus murmured, coming up with a flimsy excuse.
