Tell her everything

"Actually this was all the idea of a girl doing the internship with me." You told your sister. "She urged me to wear the skirt and panties. But as I wanted to change back into my own things, they were gone. So I had **** but to walk home looking like this." You remembered how embarrassed you felt on your way home. You lightly began to blush.

"So you tell me that a girl at your workplace made you dress up like a girl and hid your clothes to make you go home looking like this?" Alison asked sounding not very convinced by your explanation.

"Actually I don't think Cathy hid them. It's more likely that a costumer took them thinking they were hers."

"Cathy? Costumer? Her?" She probed sounding even more interested in the whole thing."

You sighed. You already knew you had no way out of it, but now you got yourself even deeper into it. "I'm working as my internship at the local shopping mall, together with Cathy from next door."

"No wonder you are wearing girl-clothes." Alison said with a smile. "With such a nice girl asking you?"

You lightly blushed again, knowing what your sister was implying.

"And your boss is O.K. with you dressing like a woman? Even with a T-shirt from La Senza, who has a store around?" Alison had asked the question just a second ago, as her facial expression changed. First her eyes got big, than she put on a big smile, the same smile she used when she was "playing" with you. "I hope you enjoy your time selling bras and panties."

"That isn't funny, sis." You complained.

"What else is it hearing your own brother is working at a lingerie store selling bras and panties while dressed like a girl? I bet you have walked by the panties a few times thinking they were cute before you brought yourself to try them on." Alison put on a wicked smile. "Show me."
