Only for the moment

"For the moment." Alison said with a smile you didn't like. "I'll keep your secret from mom."

You sighed in relief, though it was only for a short moment.

"But to do so, there must be some benefit for me."

"I'll do all your chores for the six months of my internship." You suggested.

"Hm, no. That isn't good." Alison rejected the offer. "If you would do, mom would know something is going on."

You had to agree. Doing her chores would attract attention, which you didn't wanted.

"But I have something else in mind." Your sister said again with the smile.

"And what?" You asked knowing your sister would use it to tease her in some way she thought was funny.

"I'll let you know when you come here tomorrow morning, at least an hour before you go to your internship."

You already didn't like it, but you were also happy about her not telling your mom. You grabbed "your" clothes, the skirt and the T-shirt, and were about to leave your sisters room to get to your own to put on your own clothes.

"And don't forget to bring the bra, panties and skirt."

Shocked you looked at Alison, but your older sister didn't say anything else, she only smiled at you.
