You can merge load between all 3 scenes in any order.
scene 1 - get her hard either by pressing UI button or touch her dick.
once she is hard you can jerk her off and she will cum after a while if you go fast enough
scene 2 and 3 - they will both cum after a while if you keep the speed at 50% +
NOTE - if you are noticing weird twitch during boner animation then for this scene alone try to sync your fps with your phyisics rate.
