At the incredulous expression on Alec's face, Jace just snorted. "What, it's not like we haven't shared a bed before." He said. "Yeah, when you were ten." Alec said, both dreading, and experiencing a burning desire for this. "Well, you can just sleep out here if you don't want to share beds. And besides, it's not like it matters that we're older now." Jace retorted, and at Alec's defeated look, grinned, knowing he'd won.
"I still don't like this…" Alec said, begrudgingly. "You don't have to like it, you just have to do it," Jace said, still grinning. After that, they went to work getting their fire started. And once it burned brightly, sat down around it for a while.
Jace made conversation with Alec for a while, until both were comfortably warmed, and then they agreed it was time to sleep. As Jace climbed into the tent, Alec mentally reassured himself, this wouldn't be awkward; he was just sharing a tiny tent with Jace, his best friend. Though, as he thought it, he couldn't help but wish Jace and he were more than best friend…
When Alec climbed into the little tent, he found himself already pressed against Jace, and as the other Shadowhunter laid down, he felt his chest brush his ass, and he couldn't deny the tingle that spread out from the contact. This was going to be a long night… Alec thought, as he lay down on his back beside Jace, settling in as comfortably as possible. Though he could feel Jace's side pressed against his.
Then, Alec groaned inwardly as Jace rolled onto his side, now even more fully pressed against Alec. And when Alec felt Jace throw a leg over his own, he knew he wouldn't be able to get any real sleep that night. As Jace dozed off, he mutterd, "Good night, Alec." And snuggled a bit closer.
