I love induced lactation! With the right person I think it would be wonderful. You don't need to get pregnant to do this. You do have to take some medications. Birth control pills, Domperidone to start the process. Also recommended is pumping the breasts 3 times a day for about an hour to stimulate the glands(good medical grade pump). I always thought this would be an excellent Dom/sub game to play.

Fenugreek seed and Blessed Thistle herb are good at increasing milk production.
