Want to suck his cock - detailed fantasy

I want to suck my old work manager's cock. I've wanted to for a while. He's totally my type; about 50 years old, 6' even, white, bald with a shiny head, grey stubble, a firm jawline, handsome eyes, a fit body, and a chest so hairy that a bush of salt-and-pepper hair was often visible through the neck of his collared shirt. Would love to walk into his office, with the blinds down, lock the door behind me, and drop to my knees in front of him. He'd just say something like "fuck yeah" and undo his belt, unbutton and unzip his jeans, and whip his thick cut cock through the fly of his silky spandex boxers. I'd play with his nipples through his dress shirt or polo as I teased his mushroom dick head with my tongue, and kissed it with my lips before sucking just the head into my mouth. I would savor it, rubbing my tongue back and forth across his dickhole and frenlum until he started leaking precum. It probably wouldn't take him long. Then I'd suck his whole 8" dick down my throat, not stopping until my forehead was pressed up against his belly and my chin against his balls. I'd just sit there for at least half a minute, breathing around his cock a couple of times, until he started to moan. Then I'd start bobbing up and down, out far enough that just the head's still in my mouth and then back down to the base, licking the bottom of his cock, shaking my head back and forth a bit, and working my throat muscles on it when it's in there deep. I'd do it until he says he's close, then I'd pull my head off and just look at his throbbing dick. Then I'd grab all the way around the base with my right hand and rub his dick hole with my left thumb, licking off the precum I get. I'd spit some throat cum on my right hand and start working the head of his dick while he moans. I'd tell him to hit some poppers if he had them, and suck the head into my mouth. I'd start sucking on it hard while he gets poppered up and start going down deep while keeping hard suction until he shot down my throat. He'd shoot a lot and he'd be loud, literally shouting as I drain his balls. People outside the office would hear, but neither of us would care. I'd take every drop of his cum straight down my throat, letting his dick just sit for a minute after he finishes cumming. Then I'd pull off and lick his dick completely clean, making sure I get every drop of his cum. I'd just leave afterward, I don't need to cum. Getting his would be satisfying enough.
