As Tom jerks off and huffs in his new manly smell, he notices another change starting to occur. At first he feels a bit drained, not being use to having to move so much mass. He takes a second to go back to admiring himself in the mirror, and that's when he notices. His now thick pelt of body hair is shifting colors. Going from a dark black to salt and pepper gray.
It starts on his chest and slowly spread across his body. Going down his torso all the way to his feet and up transforming his beard. Beneath all of his hair wrinkles slowly start forming as he realizes what is now happening. He's getting older!
As his youth slowly drains away as he passes 30 years old, then 40 then well into his 50's. His now fat body starts to droop more. Most men would panic at the rapid loss of youth, but Tom is loving every second of it.
As he ages he loses a little bit of muscle mass which only makes him look fatter. Which in turn just boosts his already raging hormones. He looks himself up and down in the mirror. His once youthful, but furry face now looks rugged, aged, and gruff. His hairy chest and stomach now sag lower then before, as his skin lost the youthful elasticity. His body odor, surprisingly enough, is stronger and more intoxicating than before.
Tom went from young bear to daddy bear in a matter of moments. After all of his changes Tom decides to update his profile on the dating website. His profile went from aspiring bear to bonifided daddy bear looking to meet some other bears for some late night fun.
