It was starting to get late, and with their mother calling for bed time Suzan left her bunk in order to get dressed in her pajamas. As Lauren was getting ready for her own changing she noted that her little sister was outgrowing... or had outgrown her clothes. "Um... Your PJs were older than that outfit right?" Lauren questioned
"Yes..." Suzan said and then as she got dressed in front of her older sister... They were tight to the point where she was struggling to get her head through the hole and her arms- Lauren pulled the pj shirt on which wouldn't be going back on.

Although the pj shirt wasn't boob positive or negative in design so her chest remained flat.

The heck did you do?" and was trying to get herself off the ground, but felt awkward with her mismatched top half trying to push herself up. Suzan on the other hand tried to walk away as she thought to go get more clothes to mess around with their selves Only to find her legs wasn't used to the severely increase in weight that came with a significantly larger torso. In the end...
