Cassandra's milk

Cassandra was a very smart scientist. She was in her apartment and she had just finished creating a powerful new serum for herself. If her calculations were correct then serum should alter her body to make both her breasts start lactating and producing breast milk that had growth hormones inside of it. She drank the serum and then took off all her clothes. Immediately she noticed two streams of milk pouring out of her nipples and down her body. She said "Oh my god! I'm actually making milk! Yes! It's working!" She held up her right boob to her mouth and started sucking on her nipple and drinking her own milk and immediately both of her boobs started growing bigger in response and her butt started growing bigger and becoming more of a bubble butt and she started growing taller. She noticed all of this and kept drinking her milk with pride as she enjoyed the feeling of her boobs growing bigger in her hands. She kept on drinking more and more of her milk as her boobs grew bigger and bigger and the bigger they grew the more milk they produced. She stopped drinking after she became satisfied with the size of her boobs. Each one of her boobs was now slightly bigger than a beach ball. She texted her boyfriend and said she had a special surprise to show him when he got into the bedroom.

When he walked into the bedroom he was shocked at what he found. There she was standing naked with huge beachball sized boobs and a huge bubble butt and she now stood at six feet and five inches tall. He now had to actually look up at her for a change. He said to her "Cassandra how did this happen?! You're.... you're fucking huge!!!" She explained to him about the special serum she had been working on and how it was causing her to produce breast milk with growth hormones in it. She closed and locked the door behind him and commanded him to take off all his clothes and he did.

She said to him. "You're way too small for me now little guy. I mean I know you're average size but you were always not as big as I wanted you to be and now look at you! You're even smaller compared to me now than you were before! I'm fucking taller than you are now! You look like a little boy down there! I'm giving you two choices now. Either stay a pathetic little tiny boy forever or drink mommy's milk and grow into a big boy for me." She held up her left boob in front of his month and he immediately grabbed her giant boob with both hands and started sucking on her nipple and swallowing her breast milk. She said "Oh yes! Good choice little boy! Keep drinking mommy's milk until you grow huge for me! Mommy wants to make you grow into a monster cock god!" As he sucked his erection and his balls grew bigger and harder as he also grew taller. She stroked his dick in her hand and enjoyed feeling it growing thicker and longer and harder in her hand as he sucked and drank more and more of her milk. Soon he reached the same height as her and his dick was twelve inches long and she said "Oh yes! Look at you! You're getting so big! Your cock is getting so big! Keep drinking my milk! Mommy wants to make you the biggest boy in the world!"

He continued sucking and sucking for a while until he finally stopped. He stood up straight at his new height of exactly seven feet tall. His rock hard giant erection was now eighteen inches long and each one of his balls was as big as a grapefruit. He looked down at her and said "Am I big enough for you now puny little girl?" She looked up at him and said "Yes! Now fuck me big boy!" He picked her up and put her down onto the bed and got on top of her and started pounding away at her comparatively tiny pussy. A few minutes later they both had a thunderous orgasm together as he fucked her. Afterwards he layed on top of her as they rested together in orgasmic bliss.
