May went into her room and started on her homework. She heard a loud thud and screaming downstairs. She ran downstairs and saw her mom shrinking in the living room. She picked her up and she was the size of a barbie doll. May went in the hall to see a giant foot blocking it. It was her dad who had started growing. May climbed over the growing foot and went into the kitchen. Her dad had filled the entire kitchen and her brother was there also growing bigger. He went through the sliding door and into the backyard. May still had to get over her growing dad and crawled over his legs and climbed his ass and ran ran on his back to the sliding door. When she was out, she saw her brother had grown as big as the house.
There was a loud crash and May saw her dads arm crash through the wall. He tried to crawl out through the sliding door and broke the wall. He managed to get out but broke most of the house. Her dad stood up and was 4 times bigger than her brother. He was completely naked like her brother. He saw May and her brother and bet over to talk to them. Mays mom said she started shrinking all of a sudden and her dad and brother said they started growing suddenly.
May explained about the fountain and the water and how they all drank the bottled water she brought in.
May took her mother to the large bowl and she drank from the large bowl. But she grew a bit more than her normal height. She grew tall enough to look through the second floor windows. May was now the smallest in the family. Her dad sat down and went to the fountain and drank from the small bowl. He shrank only a little and was only twice her brothers size. Her brother went to the fountain and also drank from the small bowl. He shrank until he was almost back to normal. May still only reached his crotch and had to look at his dick.
For the rest of the day. Her family stayed at there sizes. Her father tried to fix the hole he made. His size made it a lot easier to do. Her mom lounged in the pool which was like a kiddie pool for her. Her brother went to his room to do whatever. May walked upto her dad and asked when he’d shrink back to normal. He said he liked the size and might stay as it. He picked up May and got up and walked to the fountain and took a few sips from the fountain and started growing again. May felt his grip loosen and she fell on his dick. It was growing bigger and got harder. May looked back and saw her dad moaning from the growth. His legs stretched to the sides of the house and his dick reached the roof of the house. He stopped growing soon but was still hard. He grabbed May along with his dick and rubbed it up and down. He came all over the house. May was dizzy afterwards, she went up to her mom and asked if she’d shrink back.
Her mom said she would but after a while. Her brother came out of the house and saw his dad had grown again. He asked dad if he’d have a growth competition with him. His dad said yes and her brother went to the fountain and started drinking the water. He grew until he was the same height as dad. They were both huge. Her dad was next, he took some water and drank it. He started growing again. Her brother got hit by dads gigantic dick. His feet were as big as the house.
Her brother only reached his knees now. He went to the fountain and took a lot of water. He grew bigger than dad and even pushed him back accidentally and dad almost crushed May and their mom. Mom was getting tired of this and went to the fountain and drank some water. Meanwhile, her brother was as big as a skyscraper. Her dad had lost but suddenly a large voice came from the sky. It was mom. Her brother only reach her heel. She told everyone to shrink back to a decent size. Her brother shrank until he was double Mays height. Her dad was still huge after he shrank back but mom said it’s fine. Her mom also shrank back to the size she was at before.
Later that night they all had dinner outside. Her dad also shrank back to have dinner. It was a weird site. Her mother, father and brother were huge and naked and she was still normal sized. May went to the fountain and grew bigger too. She was bigger than her brother but smaller than her parents. That night, May, her brother and mom slept inside while their dad stayed outside. He had drank more water and grew as big as the house.
The next day they all had different plans. Mays mom had filled some bottles with growth water and was going to her yoga class. Her brother was taking a bottle to his girlfriends house and dad was going to the forest to grow more. May didn’t have anything to do so she followed...
