Smirk: an insolent smile expressing feelings such as superiority, self-satisfaction, or conceit
Totally fitting in this story. Leslie smirking when she caught her husband looking at his phone, because she knew what he was doing even though he tried to hide it. Mike smirking because he thought he was so smooth when texting. Iza smirking when she pushed Mike's hand out of the way to do what she wanted.
All of them are appropriate for smirking. Self-satisfaction at being able to know your lover so well. Conceit or self-satisfaction at having a little something on the side you are texting with, and thinking you are so smooth you are getting away with it. Superiority at having the tongue/mouth skills to please someone without needing that extra hand there to help.
My mate likes to watch. It makes her jealous and extremely hot.
