You took a shower and tried a dress

As both of you headed to your room, Alison had already unloaded all the clothes on your bed.

“Take a quick shower before you try the clothes, you can’t wear a tube bra and black panties. Come back and wrap yourself with a towel.”

You took a towel and went to have a quick shower. You wrapped your lower body with a towel and came out of the shower and back to your room.

“Ally! You shouldn’t wrap yourself like this. You should wrap the towel around your torso as well!” Alison exclaimed.

Alison pulled the towel from you and here you are, standing stark naked in front of your sister. You covered your shrunken penis with your hand. Alison wrapped the towel around you again, this time the towel covers up to your chest level.

Alison looked at you with a satisfied smile. “This is how to wrap a towel around you after the shower. Next, try this outfit.”

You took the white lacy dress and take a look.

“Sis, I need panties.”

“Right, I forgot. Take this.” Alison opened a pack of 6 panties and passed you a white panty.

You wore the panties and then the dress. You did a little pose for your sister.

“Fits perfectly!” Alison exclaimed.
