Whenever he'd imagined them together like this, gentle was not how he would have described Zemo's handling of him. Yet here he was, stretching his hand out over him with such a soft touch that it almost made him weep. There was no rush for this to be over. Zemo was taking his time in enjoying this, enjoying him. And why couldn't he? Bucky was willing to give him all the time in the world. He liked that Zemo was selfish for it, that he'd thrown all caution to the wind and given in to him.
If this was love, he was already knee-deep.
He heard the warning but didn't pull away. Not when he was this close to his prize. That sudden twitch and last shaky thrust of Zemo's hips into his mouth had him moaning, eager to discover this new taste. He'd swallow as much as he could, eyes upward so he could watch every moment of bliss ripple across Zemo's face. Getting him to curse like that, well if that didn't make Bucky feel smug as hell. He tilted his head back, slowly letting his lover's cock drag over his lips until it was just his tongue lapping at the sensitive ends. Because he was an awful tease and he wanted to see Zemo shiver again.
But an order came and pulled him away. Not before one last lick.
Using the back of his hand, he cleared away the spit and cum before getting up and crawling onto the bed where Zemo had gestured. He smirked, nestling himself snugly into him. "I don't think I've heard you say that before." Bucky wasn't sure what commands Zemo would give him next but he wanted a kiss, damnit and Zemo's neck was close enough now for him to sneak a kiss under his jaw.
