You idly wish that Susie was breastfed and that instead of always being a woman, you are only one when she needs it.
Suddenly, you begin to change. You feel a weird sensation on top of your head only to realize that your hair is becoming longer. You feel a tingling sensation all over your body as it becomes more feminine. You feel a tingling sensation even more powerful than before in your groin as you feel your privates change into their female counterparts. Finally, you feel your chest push out into nice firm breasts, and your clothes change, and you get a nursing bra.
Susie crawls over to you telling you that she's hungry. You lift up your shirt, and unhook your bra so she can eat.
