Jill takes a pill still a bit confused as to how it will feed Sue, and starts to wait the hour. After 30 mins she starts to feel a bit horny, and notices an odd feeling welling in her breasts, as well as the odd fact that they were starting to look a bit swollen and feel a lot more tender. She decided to fix the horny problem and began masterbating. After about a good 10 mins of playing with her pussy she orgasmed feeling much more relif, but still an odd tightness in her breasts, she went to take a shower to clean up, and maybe get off once more. 15 mins later after cleaning off she started playing with her breasts in the shower to maybe releas this pressure, she started rubbing nice and slow, and then played with her nipples a bit which apeared a good deal larger and harder than before. After a few mins of playing with her breasts she noticed as she was pulling on one of her nipples a small stream of white shot out. She gathered a bit of it to smell it and maybe see what it was, and was surprised it smelled like milk. She tasted a bit to see if it tasted like milk to, and then it dawned on her, this is how the pills could make food for a baby. She turned off the shower and went to find Sue. Sue not happy at her state as a baby and trying to think of a way to fix this, was surprised to see her sister acctualy come to check on her. Jill picked Sue up and played with her a bit before asking if she was hungry, Sue knowing she was too young for food started crying for food as she was hungry and was hopeing her sister would find a bottle for her, but to her surprise and horror Jill just held her closer to her breast and said "Go ahead dear sister, see what I learned about momies today, just for you." At first Sue refused as to her nothing could be more humiliating than having to suck her 9 year old 5 year younger sister's breast for food, but soon her instincts took over and she gave in to her hunger. Jill on the other hand found a new pleasure from feeding her tiny sister. It was odd, it felt amazing to her to have this tiny life sucking her breast and relying on her for nourishment. After Sue was fed Jill was dead set on learning what other feelinngs a baby can give you.
