Word: Estivate
...
It took Derek almost four straight weeks to realise that Stiles probably wasn't going to leave his loft. This realisation happened after he'd gone for a run one morning, the hour and weather finally cool enough to do so, and returned to his loft only to discover that it no longer smelled like himself. Well, his scent was still there - it would be difficult to remove it since he'd been living there for years already - but it was intermingled with Stiles' scent so much that Derek actually stood in the entry for a few minutes, wondering when the hell Stiles had moved in without him realising.
"Dude, close the door, you're letting the heat in!" Stiles groaned from the couch.
Still stunned, Derek did as instructed, pulling his shirt off and taking his towel off the coat stand by the door to wipe off the sweat that had gathered mere minutes into his run. Stiles had brought the stand in one day, muttering about sweat stains on the floor, and Derek had to admit, it was easier to clean the floor now that he wasn't sweating all over it.
"What's wrong? You look like you've seen a ghost? You haven't, have you? If it's Boyd, ignore anything he says about what I did last night!" Stiles said.
Derek blinked, frowning slightly. "What did you do last night?"
"Nothing that needs to be mentioned aloud. Now, what's up?" Stiles asked, hanging over the end of the couch to look at Derek.
"When did you move in? And why didn't I notice?"
"I moved in at the start of summer when I realised your place gets a better breeze than home, duh. And the reason you didn't notice is because I've been giving you pretty damn mind-blowing orgasms nearly every night since then," Stiles quipped with a smirk.
"Can't argue that," Derek muttered to himself, blushing slightly.
He honestly thought the hot weather would deter Stiles' insatiable nature, but even that hadn't been enough. Though there were a significant amount of cool cloths applied to their bodies afterwards, and the cuddling had lessened even though Derek woke up with Stiles draped over him most mornings.
"So, were you planning on telling me?"
"I thought you'd realise I wasn't estivating for the summer by the time winter came around and I was still here," Stiles said, shrugging. "Then I'd claim it on hibernating. And by the way, I'm stealing your thumb-hole jumper this winter."
"You said that last winter, and then you made me wear it all the time."
"Yeah, well you look fucking gorgeous in it; I'm still torn between wanting to wear it myself, and wanting you to wear it all the time."
"I'll buy you your own, how about that?" Derek offered.
"Oh, I knew I loved you for a reason. I made fresh lemonade; can you bring me a glass when you come back? I've got Mario Kart set up already."
"Get your own lemonade," Derek said, throwing his sweaty towel at Stiles' head as he headed to the bathroom.
"Can't; I'm going to be busy jerking off with your towel now," Stiles called with a grin.
(Derek brought him the lemonade.)
Later, after Stiles kicked Derek's ass at Mario Kart (Princess Peach rules, Der, you should know that by now), and they'd reciprocated blow jobs, Derek was lying on the couch with Stiles on top of his chest, carding his fingers through Stiles' hair. They were both sweaty again, but neither one wanted to get up to turn the air conditioner on.
"Hey Stiles?"
"Mmm?"
"Thanks for moving in with me."
"Any time. Thanks for not kicking me out," Stiles said with a grin.
"Haven't kicked you out before, not going to start now," Derek muttered, pulling Stiles up to kiss him firmly.
Stiles sighed happily against him and kissed him back. They stayed that way for another ten minutes before Stiles complained that the heat was too much, and got up to turn the air conditioner on after all.
