Showing Her Breasts At All Times

"You'll have to keep your breasts exposed... Completely exposed, no bra hiding them either... All know this might seem embarrassing, but it's important. I already explained a few reasons why, but there's many more reasons. Ones that I can't say without interfering with the experiment." The Overseer then hesitated before waiving Brit onto the stage.

Her face was a blushing mess as she slowly got up and walked towards him. She considered just running away back to her room... but she couldn't. If the research was important and could help vaults everywhere then she had to do her part... though she wasn't the only girl in the vault and couldn't understand why she was the one that needed to show her breasts.

"This is just the current role. Vault-Tech gave us a list of updates to make throughout the mission. We'd test your reactions in different situations, like having your fellow vault-dwellers grope you. We'd test new inventions like drugs to make you lactate or make your nipples more sensitive. We'd also perform regular evaluations with the other vault dwellers, getting their reactions to your exposed breasts...T-Though the mission could change at any moment so have a bit of comfort in that..."

She didn't feel any comfort or relief knowing that. Even if a new mission did appear soon, then what? Vault-Tech could always ask her to flash her breasts again afterwards, and even if they didn't, her friends would still have memorized the site of her breasts by them...

Despite that, she didn't stop the Overseer as he slowly unzipped her Vault suit and helped her take her arms out of the sleeve. He then pulled it down towards her waist and everyone gasped, seeing her lack of a bra and her bare breasts on display.

"Remember, there's no covering up any point. Not even with your hands. If you do, the data for the experiment could be ruined." The Overseer said.

Brit nodded though she was only listening with half an ear. Her mind was focused on everyone else and their eyes on her bare breasts. Only a few other girls looked away while all the guys eyes were on her... She couldn't wait to run back to her room and hide there.

"There's a lot of things that Vault-Tech would like us to do. Since this is... likely an uncomfortable experience for you, I'll let you decide what happens first." He then told her the options.
