McCree eases the thumb off the button and hooks one arm around Hanzo’s chest, pulling him up – helping him ride out the shock of the seizing muscles.
“Shh,” he whispers into his ear, nosing stray strands of hair out of the way, “I’m going to keep you safe.”
It was maybe horrible of him to say it; especially considering what he was doing to Hanzo, but… it did have the desired effect: Hanzo calming down and carefully uncurling his cramped fingers. Jesse listens to him take a rattling, shuddering breath and presses a kiss against his sweaty temple before raising the baton again, pressing the tip into Hanzo’s side.
The man jerks preemptively, breath hitching audibly, hips jerking with his cock slapping wet and swollen against his lower belly – then Jesse pushes the button and the seizing starts all over again.
Hanzo is nearly silent as his muscles shiver out of his control. His head gets thrown back against Jesse’s shoulder. Foam starts building at the corners of his mouth, and Jesse coos at him the whole time – keeps him hugged tightly to his body while pressing the baton against his side.
“I got you,” he croons at him, hand travelling lower, taking a hold of Hanzo’s cock. He stops the stream of electricity just as abruptly as he started it. “I got you. Good boy. Yes, that’s a good boy right there.”
Hanzo has no control over his body. He is helpless to Jesse’s every whim and can only whine softly in the back of his throat when Jesse starts to jerk him off.
“Good boy,” he repeats, low and harsh, voice full of affection as he presses kisses against the side of Hanzo’s sweaty face and lets him come into the warm cup of his hand.
