Launching on blackfoot's comment about aiming high when negotiating... why not do like the NOPs and tell her you want to do it every day. After you harp on that for a few weeks, maybe 1x per week will sound pretty reasonable to her.
Reminds me of that story about the kid who came home from school and said she was pregnant, got expelled, totaled her car, got busted for drugs, whatever-- and after the parent peeled himself off the ceiling, she said, "none of that-- I got a D in History-- doesn't sound so bad now, does it?"
