When running in the school relay race, Lara experiences sore breasts for the first time. Embarrassed, she doesn't want to tell anyone, but when Akira guesses, her friends take her shopping to help find the perfect cure - her first bra. It's an overwhelming experience - not only in finding the right store, but there are so many different kinds of bras to choose from; t-shirt, sports, patterned.? Luckily, Lara has the support of her friends! Maybe her new purchase will help her in the next race.Unfortunately, Lara and her friends realise that while finding a good sports bra can stop Lara's breasts from hurting, it won't necessarily help her win the relay race!
