Isaac’s least favorite part about being a werewolf though is that his hickies don’t last. The bruises fade within hours leaving him to pout when he sees his skin is once again pale and flawless. Buuuut that also gives you the excuse to frequently drag him off the redo your artwork, that makes him less pouty. It also helps that Stiles knows that his hickies heal quickly and is disgusted making comments “Can’t you stop for one day? I know that wasn’t there earlier, and its different from before”
Isaac always seemed to ‘forget’ to bring a scarf on cold days because he knew you would lend him yours, a habit from helping him hide bruises that never stopped even though he told you he can’t get sick anymore. You don’t care. And of course, he has the old scarves you’ve given him, which he always has when you aren’t around, but he much prefers you giving him yours right then because it smells like you, not just your perfume or whatever you use but it smells like you. Something that all the other wolves and creatures will smell too, he loves this the most because it let’s everyone else around know that he’s yours
Isaac was never very vocal before, mainly whimpers and gasps, (especially when you suck on his neck) but now he no longer holds back, loud whines, letting you know just how much he appreciates you attention and frustrated moans and growls as his head falls back against the bed when you tease him too much for his liking
Think of the little whine Isaac lets slip when you nibble on his ear, and his eyes fluttering shut, all his senses on fire amplifying every little touch
