Your STEP-sister finds out about your stashed away clothing. This is strictly forbidden in your household because your own STEP-dad ended up leaving the house in a dress. STEP-Mom is NOT accepting of this behavior, so your step-sister immediately tells her. To which STEP-mom leaves this to her to resolve, she's just too busy to bother.

However, after a bit of irritation, your STEP-sister starts to cave when she sees you. You... look... amazing! She decides she'd rather you embrace this, and agrees to keep it a secret as long as you give her runway shows now and then.
