Your sister came in

Suddenly you heard a knock on your door. "Hey Alex. Can I come in?" It was your sister Alison.

"Sure." You replied.

A second later the door opened and Alison came in. "I thought that as you have to look girly for your work I could ... Why are you dressed like a girl?"

"I fell asleep yesterday without taking them off." You said truthfully.

"Are you sure?" Alison asked doubtful. "Didn't you wear yesterday a bra for flat chested girls?"

"Yes, I did. Why do you ask?" Alison didn't responded to your question with words, but by pointing her finger at your chest. You looked down and were totally surprised as you saw not the plain white bra from yesterday, but a shiny red one with two round, empty cups. "What the hell?" You put your hands on the bra and pushed the cups down. They felt firmer than the ones from yesterday and as you took your hands away, the cups pushed out again.

"Seems like your 'girlfriend' tricked you into wearing a push-up bra." Alison began to giggle.

"Very funny, sis." You said a little annoyed. You put your hands on your back and tried to open the bra hook, but you couldn't get it done. "Could you undo it for me?" You asked your sister.

"Sure, but you should learn how to do it yourself." She stepped behind you and easily opened the bra hook.

You slid the bra's straps off your shoulders and let the red bra fall on the floor. "What did you want from me?" You asked Alison as you sat down on your bed and took of your shoes.

"Oh, yes. I nearly forgot." Alison said. "I wanted to ask you, as you have to spent the next two weeks at work looking like a girl, if you would like me to teach you the things you need to know?"
