YES
LOVE IT
*stamps seal of approval on it*
I love the thought of Gabriel lounging back and watching and getting off so goddamn hard at Jack being the one on bottom for once in his miserable roughly 200 year old life (because they’re both the same age but Jack is fucking ancient tbh). Like.. he’s having the time of his life. He’s tickled pink just watching the look of slow realization on Jack’s face when it hits home that he’s not in the prime of his life anymore and, in fact, an old man. An old Alpha. Bested by a younger, thiccer, more powerful Alpha.
He probably jerks it so hard watching Jack go through the five stages of grief while Jesse works away at him, before finally settling on moody acceptance.
