Tiff couldn't just stand there when Katie was in such distress. As quickly as possible she tried to milk Katie, but she wasn't managing any better than Katie had. Realizing what she was going to have to do she looked at Katie, "I hope you don't mind."
"Please," Katie begged, "Just help me."
Without further hesitation Tiff took one of her nipples in her mouth and began to suck.
Her original intention had been to spit the milk out, but the sweet taste of the warm, creamy liquid surprised her and she swallowed. It should have disgusted her, but instead she found that she liked the flavor. Katie's milk was possibly the best thing she had ever tasted, whether it was due to the strange process that Katie had gone though, or the fact that all humans were designed to love the flavor of mother's milk. Tiff found that she didn't care, the taste made it much easier. She was so involved in what she was doing that she didn't realize that her shirt was starting to feel loose, especially in the chest area.
Practically sobbing with relief, Katie wrapped her arms around Tiff's shoulders, pressing her against her enormous belly.
By the time Tiff had drained the last drop of milk from the one breast her clothes were at least a size too big and Katie was a head taller than her. Even when her pants fell right off her shrinking frame she didn't notice as she began sucking Katie's other breast to get more of the wonderful milk. It tasted so good and felt so soothing she never wanted to stop. The more she nursed, the easier it got, almost like Katie's nipple was getting bigger in her mouth and easier to suck at. Her panties fell away, revealing a hairless, pre-pubescent pussy and she found herself having to stand on tiptoe to keep nursing.
Katie bent down a little to make it easier, her eyes closed in the bliss of her relief.
At last Tiff found herself unable to get any more milk out of Katie and she stepped back, feeling weak and exhausted from what she had done. Sitting down on the floor she felt full and content. Her shirt was hanging off her like a tent, but she didn't even notice, for a delightful warm feeling filled her and she found herself sitting in a puddle. She had wet herself like a little baby. From the floor she looked up at her friend towering over her, "Katie I made pee-pee on me."
At last aware of what had happened, Katie looked down and saw that Tiff was was no more than two years old, "I'm so sorry Tiff."
"I fink I need a baf," Tiff replied, putting her thumb in her mouth.
