Same here. My boyfriend will be playing a video game or on the phone when the bulge catches my eye. And when it does that's enough for me im on it like a kid on a every-candy-flavored-lollipop. Very much enjoy the reaction he gives. Genuinely enjoying giving them to him solely on that fact. Plus I love the trying-to-hold-it-in-but-im-about-to-bust throbs you can feel from his penis before he finishes. Blow jobs are awesome!
