Nothing But Trouble

[Sterekdrabbles challenge for 02/22/19: “wrist, slump, polish”]

On AO3.

“Psst,” Derek heard. “Hot stuff.”

Stiles Stilinski sat slumped in his seat, his leg blocking the aisle.

Derek kept his head down. If only Mr. Finstock wasn’t ranting at Greenberg in the hall. He’d scold Stiles for his distracting behavior.

“Der-rek,” Stiles sing-songed. Derek’s glance revealed Stiles polishing his nails against his shirt, like some gangster in an old movie, then winking at Derek!

Derek blushed. Worse, his wrist started itching but he didn’t dare scratch now because Derek knew drawing attention to one’s wrist was body language for sexual receptivity.

He didn’t want Stiles to think that.

Did he?
