Chang worked at a factory in China where flip flops were manufactured. The working conditions he endured were pitiful, and it wasn't uncommon for people to get injured or even die at work. The factory he worked at was next door to an abandoned nuclear plant that went unattended for years. Radioactive material leaked into Chang's factory. One day he started shrinking while working as the radioactive material got on his skin. He leaped onto the conveyor belt before he shrank all the way down. He shrunk down to less than an inch, but as he started to realize what happened, the sandal went through the paint machine to get it's color. The paint hardened and left him stuck, face up, near the tip of the sandal. Before he could do anything, he was crammed in a box with all the other flip flops to be shipped out. He spent hours in darkness until a blinding light appeared above him as the box was opened. He was unpacked and placed on a shelf. Within and hour, Emily, a young college girl, was overjoyed with the new red flip flops she had purchased, completely unaware that a man was shrunk and stuck on them. As soon as she got home she slipped them on, and Chang was forced to be right under her big toe. Chang happened to be shipped to one of the worst places possible, Miami, where the intense heat made Emily's feet sweat intensely. The incredible heat coupled with Emily's foot sweat, which acted like lubricant, caused Chang to get an erection. Every step got him closer and closer until he finally came under her foot for the first time. Chang came on Emily's foot every day that week as her red pair quickly became her favorite pair of flip flops. She wore them often, and she always wore them when she went to the beach, which happened to be where her feet got the hottest and sweatiest. At first, Chang was disgusted when Emily wore him, but he came to love it, because every time she wore him he got to cum, which he wasn't able to do on his own since his arms were stuck to his sides. He was especially grateful for beach days when her feet were the hottest and sweatiest because her skin was very soft, which made it easy for him to use his teeth to scrape skin off her toe for him to eat. Her feet were also drenched in sweat on those days, allowing him to drink plenty of sweat, which he needed to live. Being worn meant he got to eat, drink, and cum, three things he loved. He also liked when Emily would let her friends borrow her flip flops so Chang could get to taste different flavors of skin and sweat and cum on the toes of different girls. When Emily wasn't home, sometimes her mom or little sister would wear Chang for the day, which was fine with Chang, because being worn was the best thing that ever happened to him anymore. Spending his days under Emily's foot, as well as the feet of her friends and family, was actually much better than working in the factory, and Chang was incredibly grateful towards Emily for buying him that day, even if nobody knew he was having the time of his life under their feet.
