Bucky just laughs softly - maybe to offset the fact that he's a little nervous, too, but mostly that nervousness feels more like excitement, like desire, and when he glances up at Steve, his eyes are dark, maybe a little more gray than blue, and his grin is probably a little dangerous as he settles himself back in between Steve's legs, running one hand slowly, lightly up the inside of his thigh, resting the other on Steve's right knee.

"Well, I like you, too, Stevie. See if you like this."

And he slowly, slowly drags his fingers to the crease of Steve's leg, then to the base of his cock, holding it steadily - and still gently - as he leans down to lick a slow, wet strike up the underside, from base to tip, as his other thumb brushes slow, slow circles on the inside of Steve's knee. God, Bucky feels overheated, like he needs to touch Steve more, but he does his best to channel it into control, into making sure Steve gets the full - slow - experience. If those movies only showed him suckjobs on fast-forward, Bucky wants to show him what else is on the table.
