Oh God, your McHanzo headcanons are lewd as hell, I love it. Here is one: Jesse making Hanzo wear a buttplug when they are going to some festival for example, and then he fucks him on some backstreet, enjoying that he is nice and ready for him.

heeelll yaaaaahhhhh, friend! 

I want it to be in Hanzo’s home where they parade huge paper dragons through the streets and everything is alight with colorful lights and they have small shops with Takoyaki and sticky sweet rice balls, and just everything is very traditional and beautiful and happy.

And in one of the side streets just outside the radius of the light, McCree has Hanzo against a wall, prosthetic hand in his neck, keeping him very firmly where he wants him. Hanzo’s pants are bunched around his metal knees, and they’re wide and loose enough not to hinder McCree at lifting Hanzo’s leg at the knee, pulling it up high to the side, marveling at Hanzo’s flexibility – and the sight of his ass; that dark space between his cheeks glistening and wet with lube; so alluring; teasing him into exploration.

“Do it quick,” Hanzo is whispering forcefully, head turned towards the mouth of the alley, dark eyes glistening like liquid tar from the light shining in. He’s watching people meander by, talking animatedly, and he should be indignant that McCree has no virtue and wants to defile him in such a degrading manner, but in actuality he wants it just as much, and has put up no fight other than pretending to be annoyed.

When Jesse finally fucks him, that ridiculous, heavy belt buckle is slapping against Hanzo’s ass because McCree has opened his jeans just enough to get his dick out.

Hanzo is still staring at the mouth of the alley but he’s not really looking because he’s kind of swimming away, coasting on the feel of McCree’s thick cock spearing him open and seemingly pushing in even deeper than usual in this position; it’s like he’s fucking right into Hanzo’s belly and warming him up from the inside, and he almost wants to stop clawing at the brick of the house he’s leaning against, so he can reach down and cup his belly and feel whether there actually is a bulge from McCree ramming him.

McCree is grunting softly behind him, and he sounds delighted, and when Hanzo manages to turn his head enough to peek, there’s a big, self indulgent grin on McCree’s face, teeth viciously dug into the butt of his cigar, eyes staring down where he’s deep dicking Hanzo in public just like he probably always fantasized about in his too long showers.

“Gahdamn plug’s been the best decision of mah life,” McCree croons between clenched teeth and Hanzo huffs in annoyance, even as his body flushes with pride and excitement.
