Not quite

Michelle gains a decent pace forward while she thinks Joy is farther behind. Much to her dismay she feels a strong tug on the tied straps on the back of her top. Before she can react, she immediately feels the top give away and slide off of her back. By this point Michelle has made it to the stairs but is only in her lingerie. Joy tosses the top down the stairs as Michelle screams and covers her black bra with white frills on the sides of the cups.

Michelle must keep pressing forward DC 15 since Joy has caught up.
