Another fun oral position to try is "under the sink." She stands right next to the side of the bed and squats down a little. There should just be enough room for you to lay on your back on the bed and place your head between her legs. She is mostly in control of her own pleasure. She can squat further, tilt, lean back, etc. This position is pretty easy for you both to do. She just needs to give you enough room so that you don't strain your neck.
