Even Brock was caught a little unprepared when Steve suddenly came, though he had been trying to figure out what the hell he was going to do with it once it showed itself. It might have been best that he didn't have time to plan out his reaction with the suddenness because when his mouth filled with Steve's semen - was it supposed to taste like that? - he gagged a bit but actually swallowed rather than pull back and get cum in his hair.

He only pulled away when he was certain that he wasn't going to have to explain why he had Captain America's spunk drying on his face and hair. He licked at a line of cum that had formed at the corner of his mouth and gave Steve's thigh a pat. "As eager as last time. You holding out for me?"
