Bucky's metabolism makes him need to eat a lot, so as much as he'd like to throw the protein bar down and follow Sylvie immediately, he waits for her to turn away and then shoves pretty much the entire thing into his mouth and chews quickly, watching Sylvie's hips sway their way down the hallway like she's just trying to drive him crazy.

He chews fast enough that Bopp up at him with her ears perked in concern, and Bucky shakes his head a little as he reaches down to put his hand on her head.

"Stay," he says once he's swallowed, patting between her ears and draining the bottle of water before dropping it and the wrapper, uncharacteristically messy, and then following her down the hallway. She's just made it to the doorway of his bedroom when he catches up to her, arms wrapping around her from behind. He buries his face in her neck and inhales, sliding his good hand up under her shirt and then her bra, palming her breast as he pulls her hips back against him.

"You drive me crazy," he says against her ear, chuckling happily as he walks her into the bedroom, kissing under her ear. "Absolutely insane."
