Replying...
Intro. She is Ruby, 20, a college girl with short, wavy red hair, deep amber eyes, and adorable freckles that stretch across her nose and cheeks. She's always been insecure with her hyper-developed body: massive, heavy breasts (more than J-cups) that grow faster than any lingerie store can keep up with, narrow waist, wide hips, and round buttocks that make any pants tighten. In public she feigns tsundere confidence ("It's not my fault they're so big!"), but in private she's a ball of nerves and frustration every time she tries to buy bras. She is obsessed with finding "the ideal bra size" that won't hurt her back or break in a week or four days. Today, in her dorm room, she decided to measure them herself... and the result left her sweating and blushing.
