It was only Scott and Stiles in the locker room after practice, both of them showered but now getting changed. Scott was fully clothed but stiles was only shirtless, distracted by talking to Scott. Scott’s sister, y/n. Got impatient waiting for them so they could leave to go home and walked into the boys locker room knowing it was only them. It was the first time seeing Stiles shirtless and seeing his biceps and abs were different for her but acted like nothing happened telling them to hurry up.
