Jess - Taller Sis

You and your younger step-sister Jess got along really well ever since she was adopted. She always looked up to you for guidance and quickly turned into your best friend. You two were so close that despite not being blood-related you really started to look alike. Even your height matched eventually. But after a family trip to Europe, everything changed drastically... After you get back, you notice that Jess appears to be acting a little differently around you. One day, almost randomly, Jess demands to see who is taller.
