Demeter would approved of his, Grant thinks to himself as he jerks off in front of TK, pretending the other is merely but one of his many adoring fans who would've been doing this very same activity, albeit less personally. Fraternal bonding was so important. Even a philistine of Greek mythology like Grant knew this. So... yeah. That was his excuse.
And he was good at it too, making his dick seem long, thick, and desirable. Something about showing off to someone like this —someone not even naked themselves— fueled his exhibitionist streak he didn't know he had until a few years ago. Turns out he liked being admired for the girth blessed to him.
Maybe it was Demeter's doing. Giving him such a big goddamn cock full of spunk to fulfill the "fertility" part of her domain.
"You just gonna watch?" chuckles Grant, still stroking. "At least get yourself off too, man. No harm in enjoying yourself with me..."
