Bruce stopped what he was doing pulled out, picked Stephanie up and kinda like one of those classy dancing shows he twirled her around to face him. "I love you Stephanie."
It'd been important enough to Bruce to tell her again face to face that he completely disengaged sex mode for the sake of being a good, romantic lover. Stopping just to tease was one thing but Bruce was a hopeless romantic under all those layers of the Bat.
