Zenyatta being curious about McCree after genji telling him about the other man. Figuring out how laid back and easygoing the man is in regards to sex and wanting to know how well he can take that thick cock inside of him. McCree being so big he barely fits and zenyatta swearing he can see the iris as he gets fucked nice and slow.

… fuck… this is… *licks lips* this is real good shit. I can just see it in front of me:

Zenyatta so thin and silvery beneath this hirsute bulk of a man; McCree ranging above him like a mountain, cigar in the corner of his mouth, watching under heavy lidded eyes as he stares down between Zenyatta’s legs and contemplates that small robotic pussy he’s been presented with.

He’s got one big hand under Zenyatta’s ass, lifting him up for better perusal. He reaches for his cigar and ashes off into a tray to the side before he thinks better of it and leaves it there to peacefully glow as he takes his cock in hand and lifts it up to smear the head along those pretty, silicon teal folds because his cock is too heavy to stand on its own.

“You sure this’ll fit?” he mumbles a bit dubiously, pressing closer, making Zenyatta spread around the blunt, broad tip. Zenyatta’s voice glitches, his long fingered hands patting nervously at McCree’s barrel chest and thick belly; very careful so he won’t catch any of the dark hair between the joints. “Yes, it will.. it will adapt.”

And McCree hums in contemplation and then shrugs his shoulders and nods and starts going to work.

moves his broad hips in little, rocking thrusts; coaxes his dick in inch by inch and making that pretty little fabricated cunt spread around him. He can hear the soft humming of tiny machines as they scrabble to readjust; can feel the slick, welcoming interior open up around him but just barely enough to allow entrance – and all in all it is a very smooth entry, all considered; only that Zenyatta’s voicebox is crackling with a fuzzy sound, the lights on his forehead all individually dimming and brightening in uneven intervals.

Jesse asks him if he’s alright but he seems to be totally zoned out; like getting spread by so much dick had his processors reeling.. which is pretty flattering, since he hasn’t even done any work yet.

McCree slowly starting to fuck; a very easy, almost sloppy rocking motion of his hips, eyes still heavy lidded, almost bored looking as he fucks, if not for the small slip of tongue at the corner of his mouth and the steep fold between his bushy eyebrows as he concentrates on dicking Zenyatta slow and even; listening to the obscene squelch of his artificial cunt and how it suckles him in again and again, the silicone lips hugging tight around his dick and kissing up to his balls whenever he pushes in especially deep.
