I added more commands:

Deeper - she sucks you in deeper

Higher - she sucks more towards the tip

Look at me - she looks up at you

There are some limitations, such as, if she is deep throating you and you say "look at me", she will try to look at you, but she may be too far down to make eye contact. When you say "tip", she will move to the tip, but her gaze will also shift downward and to a very close focus point, like she's really in the zone focused on sucking the tip. Then if you say "look at me" she will keep sucking the tip, but she will move down to get to an angle so she can look up at you, but this may make the cock pop out of her mouth. You'll have to experiment. I know it's such drudgery having to spend hours with this girl blowing you, but we'll get through it lads!
