I photographed Lorna 2 weeks ago (sorry for the delay in posting) and she looked very lovely her boobs were amazing, she is really heavy in the bust but not in the tummy area.
Lorna's boobs are still all natural and so I quizzed her a little and she said that she couldn't really explain the size change except she has recenlty changed her contaceptive precription and thinks it might me because of that

Apparently it made a difference to her in her early 20s when she had a spurt then.
Her nipples didn't really appear to be darker and she was very bubbly and her normal self so I didn't witness any raging hormonal activitly

Eventually I told her what everyone suspects and she smiled and said that she was not surprised that everyone was a bit puzzled and that she would love to get pregnant one day.
Anyway this is my latest update as promised.
