No, she can't, and so, she goes downstairs.

"Listen to me young lady, unless you come down to help your brother and his friends, i'm going to make you come to school naked, so unless you don't want to be seen naked by your classmates, you better come down", Natalie's mother yelled in a stern tone.

"I....", Natalie was out of words, it was bad enough that she had to be naked in her house, but to go to the school completely naked it was another thing, and so, she, reluctanly, decided to comply. "Yes mom", she simply said.

And so, Natalie slowly and nervously, walked downstairs accompanied by her mom, meanwhile downstairs...

"Okay, so now that we have finished our homework, where's that surprise you promised ?", David asked Luke.

"Don't worry just keep waiting a little", Luke replied.

"Are you sure you didn't lie about it so we would do your homework?", Ashley questioned him.

"If you aren't so sure about it, then look at the stairs", Luke calmly replied, to which, all of his friends looked at the stairs, to witness the naked Natalie.

"uhhg", groaned Natalie, "Don't be shy honey, present yourself to Luke's friends", her mom said, "fine..i'm Natalie, and i'm..Luke's sister", Natalie struggled to say.

"Oh dear goodness, why is your sister naked Luke ?!", exclamed Emily surprised.

"Is that...the surprised...that you talked about...?", Josh said shyly, as this was the first girl he had seen naked in his life.

"Wow, what a body!!", commented David.

"I didn't definitely expect it, to be honest", Ashley commented.

"C'mon Natalie, just help your brother with his homework and then you can get back upstairs", Her mother said, before leaving the living room.

"Soooo... why are you naked?", Emily asked curiously.

"It's a long story, but whatever..., let just get over with this quickly", Natalie said hasty.

"No, if i can", Luke thought for himself.
