In a manner of speaking, I suppose that was a "hell" of a blow job. I've had guys refer to mine as in much better and more flattering terms. She should learn to look up at the guy with smiling eyes, use her tongue all over it, just loving on it in general and making him feel like his cock is something special. And DON'T make him have to do a lot of the work himself. You make him cum, rather than him having to jerk himself off. Yuck! Then open your mouth or close it around him, either way, and take every drop inside and swallow. Then smile at him again, and if it tasted good to you, maybe even say, "Thank you."
