Bucky groans before he shifts just a little, sore and trembling, but it's not enough, he's still in the middle of his heat, still shaking and needy. And then Steve bites him and he makes a strangled noise, halfway between bliss and frustration as he tries to twist himself on Steve's cock, moaning all the while. He wants to face his mate, to return the bonding bite. He growls lowly, an encouraging noise.

The sheets are going to be a sweaty, sticky mess by the time they're over, bur right now he doesn't care, still rocking his hips hard against Steve and moaning loudly. He's not bothering to be quiet right now, and his cock is already half-hard again, only moments after spilling seed onto the sheets.

He lets out an encouraging whine, wanting desperately for it to continue until he's so exhausted he can't move anymore.
