First day of school after summer vacation

Yuki stood in front of her mirror, frowning slightly as she adjusted her outfit for the first day of the new semester.

She had gained a little weight over the summer — nothing ****, but noticeable. Her breasts had grown fuller and heavier, pressing tightly against the buttons of her crisp white button-up blouse. Her ass had become rounder and softer, making her short, flouncy black skirt ride up higher on her thick thighs than it used to. Even her face looked a bit softer, with fuller cheeks that gave her a cuter, more innocent appearance.

Underneath the seemingly modest schoolgirl look, she wore her secret slutty pink lingerie set — a tiny pink lace bra that struggled to contain her bigger breasts, and a matching pink thong that disappeared completely between her fattened ass cheeks. The thin lace front panel clung tightly to her smooth, shaved pussy. Finally Yuki put on her black high heels.

Yuki had recently joined the Public Speaking Club, hoping it would help her overcome her lifelong shyness. Today was the first official debate practice, and she was already nervous.

Yuki realized she was already running late thankfully her first period was study hall so no big deal.

She hurried to school and reached her locker just after the bell for first period had rung. The hallway was almost completely empty now — everyone else was already in class.

Yuki quickly spun her combination, opened the locker door, and leaned in to grab her math textbook from the top shelf that she needed for 2nd period.

As she stretched up on her tiptoes, the back of her black skirt rode up dangerously high on her thick thighs. The short, flouncy hem barely covered the bottom curve of her plump ass, and the thin pink string of her thong was clearly visible between her soft cheeks.

She didn’t notice.

She was too focused on being late and trying to hurry.

She grabbed the book, closed the locker, and turned to rush toward her first period class.
