Remus could hear Sirius finally emerging from the bathroom and rolled his eyes without looking up from his book. That moron stayed in the shower longer than every girl in Gryffindor. Grabbing the nearest scrap of paper, he stuck it in his book to save his place. He looked up and opened his mouth to ask if Sirius wanted to work on their Potions homework that afternoon but nothing came out.
Sirius had his arms above his head propping himself up by holding onto the hangings rail of James' bed. He was wearing only a white undershirt and his pants and the two articles of clothing didn't quite meet in the middle. Remus could see a sliver of Sirius's abdomen along with the top of both of his pelvic bones. Last summer, before their fifth year, had seen Sirius shoot up at least four inches and he had become much leaner, toned even. Remus could feel his mouth going slack but couldn't find the presence of mind to do anything about it. He clenched his fingers to curb his sudden yearning to touch Sirius' exposed skin. His eyes slowly roved up Sirius' torso, finally reaching his face and realized that Sirius was looking directly at him. And smirking.
Remus slapped his mouth shut and blinked while he felt his face light up like a fairy light. What was wrong with him?! His eyes swiveled to James who was sitting on his bed grinning, and saying, "Hello Remus! Earth to Remus!"
Remus felt his face break into a nervous smile and said, "Hey! Yeah, what? Sorry, what? I was just, uh, thinking…" Maybe they won't notice that I was staring at Sirius specifically, he thought worriedly.
"I was asking if you think we could still finish our Potions homework on time if we didn't start till tomorrow?" asked James with an indulgently amused smile on his face. "Sirius and I had a brilliant idea in Charms yesterday for a prank."
"What in the world were you thinking about so intently?" Sirius questioned, "Or were you just struck dumb and deaf by my stunning good looks?" he waggled his eyebrows and shook back his damp hair.
Remus almost choked on his own tongue but recovered himself quickly and glared at Sirius while responding to James, "I'm sure we could figure it out easily. What did you have in mind?"
