Derek should not get hit by magic bullets more often. But, as his adrenaline had leveled into something his brain could work with, Stiles decided that Derek should definitely be shirtless more often. After that day, he had revisited that thought often. Derek, shirtless, preferably close up against him, and why had he never tried? And with Derek gone, Stiles sadly had to curse internally as he admitted that no matter how much lip, teeth, claw or raw, animalistic passion Theo put into their sessions, it just didn't do the same for him as Derek's lack of shirts had done.
