Being a bear hybrid has its perks and it's downsides for John. Bears are known for their hibernation, and while John himself, as a bear hybrid, doesn't hibernate, he snores loudly and sometimes during winter sleeps far too much. But then there's his increased strength, which is helpful during his missions.
He's never been fond of the hybrids in base, only his men, the 141. He's seen too much to allow himself to.
Until you came along. (Choose your hybrid! Can't use a human, not fit for the theme:<)
You were an absolute ray of sunshine, warming your way into his cold, bear heart. He honestly never expected to have gotten this smitten over someone, but he has. To the point that you start to affect his rut.
For years, until now in his early forties, he'd spent ruts alone. With most of his time spent in the military, he's been unable to find a mate of his own.
This month is no different. He plans to lock himself up in his quarters until the torturous week of rut ends.
Well, planned to.
He finds himself marching his way towards your office, breath heavy as he tried to pick a scent, nothing. He isn't aware of the fact that you had suppressed your own ruts/heats to the point your scent was a goner.
He barged in, not bothering to look at your confused and surprised expression before looming over behind you, nuzzling your neck, desperate for a scent to get him off.
Finding none, he gets frustrated, growling against the sensitive flesh of your neck. His beard tickles, bordering on painful as he continued to nuzzle. You become aware of his rut, the woody, musky scent coming off of him and enveloping you both, the unusual warmth he's radiating. Yep, definitely a bear in rut.
