Yes

You stood there for a few seconds, hoping your sister would tell you it was a joke. But she didn't. You sighed. You opened the skirt's zipper with your hands and pulled it down. You blushed heavily as your sister looked at you in pink panties.

"And what about the T-shirt?" Alison asked.

"What about it?" You asked in return.

"Aren't you taking it off and show me how you created these two small mounds on your chest?"

You looked down and saw the T-shirt still had the two small breast-like mounds on it. You had totally forgotten you were wearing a bra with inserts. "Do I really need to?" You asked blushing again.

"If you don't want me to tell mom?"

Again you sighed. You didn't wanted to show your sister you were wearing a pink bra, but even less you wanted your mother to hear of the whole thinge. You pulled the La Senza T-shirt over your head and revealed the pink T-shirt bra.

"Looking good, bro. Pink is just your color." Alison teased you. She was clearly having fun seeing her younger brother wearing pink panties and bra.

"Are you satisfied now?" You asked feeling uncomfortable.
