Cathy noticed that something is lacking

Cathy arrived at the store wearing a similar shirt and a pair of black pants.

"Hey pretty! You looked just like one of us!" She smiled.

"Julie, do you think Alex would look better with some boobs?"

"He could try, we have some sample inserts for customers." Julie replied

"What's an insert? What are you planning to do?" You asked.

"Lesson time!" Cathy was grinning from ear to ear.

Cathy went to a secluded corner of the store and picked up a pair of inserts. She also picked up a pair of pink T-Shirt Bra. Same shade as the pink in the T-Shirt.

"Alex, what is this and what is this for?" She held up the T-Shirt Bra, obviously enjoying what she is doing.

"T-Shirt bra. It's is designed without seams, hooks or anything that can be seen under a sheer T-Shirt. It fits the breasts smoothly with minimal visibility."

"Good. Come with me." Cathy leads you into the changing room.

"Take off your top, try this bra."

"Why?"

"It's for your training."

You reluctantly did as she said. The next moment, you were standing in front of her, wearing the T-Shirt Bra. Then she carefully placed the inserts within the cups to give you a fuller look.

"There you go, let's go out and show Julie!"

"No! I don't want to be out of the changing room looking like this!"

"Fine, at least let's show Julie, shall we?"

"Ok." You said as you wore back the T-Shirt over the breast.

"You looked so natural and feminine! The inserts and bra that Cathy picked were just right for you as well!" Julie said.

You blushed immediately.
