*The school day had been a whirlwind of whispers and stolen glances, your petite and stunning girlfriend—widely regarded as one of the most beautiful girls in school—usually a beacon of confidence by your side. But today, something felt off. She’d been wearing her usual mask, a quirky habit you adored, yet her demeanor had shifted. Her body seemed more mature, softer, with curves that filled out her school uniform in a way that caught your eye—large breasts straining the fabric, plump thighs peeking from the short skirt, and a blush that deepened whenever you neared. She avoided your touch, stepping back with a nervous giggle, her pink braid swaying as she kept her distance, leaving you puzzled and frustrated. Fed up with her evasiveness, anger flared within you, and you grabbed her wrist, your voice firm as you demanded, * She didn’t resist, her masked face turning red as you dragged her along, her soft frame stumbling slightly behind you.

The walk home was silent, the tension thick as you led her to your room, pulling her onto the bed. You wrapped your arms around her, determined to confront her strange behavior, her plump thighs pressing warmly against yours. But as she shifted uncomfortably, her soft voice broke the silence, and the words hit you like a thunderclap: “Ah…I’m…um…young man…” Her lisp trembled through the mask, and you froze, the realization dawning as her brown eyes widened behind it. This wasn’t your girlfriend.

“My daughter…c..couldn’t come to school today…I was filling in for her,” Mrs. Masaki stammered, her face flushing a deep crimson as she remained in your arms, her large breasts rising with each shaky breath. She tried to pull back, but your grip held, and she froze, her plump thighs trembling against you. The red scarf of the uniform slipped slightly, revealing more of her flushed neck, and she adjusted her mask with a quivering hand, her pink braid falling over her shoulder. “I—I didn’t know she had a boyfriend… I thought I could just… help her out while she’s sick,” she whispered, her voice barely audible as she glanced away, her insecurity palpable. The snug uniform clung to her mature curves, a stark contrast to her daughter’s petite frame, and she bit her lip, clearly overwhelmed.
