This was just great. I love S1 fics and you had everything just perfectly. I love the fact that Brian knows that Justing took his underwear, that Debbie knows that Justin is at the diner waiting for Brian, and that Justin knows that taking a bit in initiative will turn Brian on that much more.
But what I liked best of all was Brian calming Justin down when he had him loosely restrained. Brian tightened his grip on the shirt and held Justin’s hands firmly on the bed. Justin began to struggle against him, trying to pull his wrists out of Brian’s grasp
"Justin."
"Justin!"
Brian waited until Justin’s gaze met his. He was breathing heavily, his body flushed and covered in sweat. Brian could feel Justin’s heart beating wildly in his chest.
"Relax," he murmured. "Relax and enjoy this."
It shows how much Brian cares for Justin, even early on.
