Admit you do

"Well umm... I guess it's fun..." You say, not wanting your secret to get out, but deep down knowing it's a little late for that.

Samantha rolls her eyes and giggles, "Oh come on, it's just us here you can tell us. You like it and I bet you've even done it before right?" She pushes the question, getting closer to you as Becky does the same the other side.

Sandwiched by them both you blush and admit, "Okay I do really like dressing up, I've borrowed some of my Mom's or Sister's stuff before though please don't tell them!" You beg, cursing yourself as they could easily get you in trouble.

"Relax, your secret is safe with us," Becky reassures you, "It's adorable that you want to dress up. So what were you thinking about wearing tomorrow?"

"Um Well like you said earlier jeans and a te..." You're interrupted quickly by Samantha.

"Oh nonsense! We just have to get you in a dress or skirt, right sis?"

"Yes! With your body it would be a shame not to show it off, I have the perfect little pink and floral sundress you can wear sweetie." Becky offers, waiting for a answer.

As much as your brain is telling you to deny the offer and fight your urges, your body doesn't agree as you nod enthusiastically. "That sounds perfect, thank you." Is all you can muster up eventually.

"Don't you worry your pretty little head, me and Becky will sort out your whole outfit for tomorrow... On one condition though." She adds a mischievous grin on her face.

"O... Okay what's the condition...?" You ask as Becky seems just as curious.

"We're going shopping as girls right? So you'll only be able to buy girls clothes, which in turn is my condition. You're going to be our sister for this entire vacation!" She states proudly, Becky looking a little less sure but no less happy.

It was like one of those sissy stories you'd read online, your nearly perfectly fantasy as you agree to her terms, "I'd love that, Big sis." You say the last part woodenly and yet it felt natural.

"Girls dinner is ready!" Nikki calls from the other room as Samantha gives you a little kiss on the forehead.

"Be sure to tell Mom that it's your decision hehe."
