The fangs and the claws he could work with. The glowing eyes and weird wolfy instincts that had him snuggle in a pile with grown men and teenagers didn't even blip on his radar these days. The urge to sniff the mailman? Isaac could handle that with grace. He could fit a lot of bizarre into his life. But a weird wolf dick that came with a knot? Fuck no.

Or Isaac hits wolf puberty and he turns out to be a special boy. Stiles helps.
