She arrives at the office

Elizabeth arrived at her younger sister's building promptly at 6am, as instructed. As she rode the elevator, she cringed again at her outfit. She'd intended to wear one of the more demure skirts she'd bought, but in the dark of the early morning, she'd grabbed the shortest one and been too rushed to change after she realized she was walking out of the house dressed like the office slut.

Now she strode down the hallway to her secretary's desk, aqua miniskirt and matching bra, white sheer button up, white pantyhose, and 4 inch white patent pumps completing her look.

She saw her little sister coming out of her corner office, and reflexively chirped, "Good morning Ma'am."

Megan did a double take as her older sister sat down at the desk at the front of the department, decked out like a bubbleheaded assistant. She stood with her mouth agape, staring for a second before she relaxed. Of course, Elizabeth was only adapting to her new job. She had to make sure she didn't slip up and reveal she was working an entry level job for her own younger sister. Megan collected herself and stood a bit straighter.

Elizabeth put her purse and papers away and readied herself for a day of answering phones and scheduling appointments. She noticed Megan standing and gawking at her a bit, but as soon as their eyes met, her sister seemed to straighten. Megan cleared her throat. "Good, I'm glad you're here, 'Betty'." her sister clipped, and motioned toward her office door. "I need you to take the stack of papers from my out box on my desk. Please file them."

"Of course, uh, ma'am" Elizabeth started, before another person stepped into view. An older woman stepped out of Megan's office. It was the CFO. Elizabeth caught herself before stammering, "When would you like me to start, Ms. Hastings?"

"Right now of course." Elizabeth nodded to Megan and then to the CFO, and darted into the office to grab the papers.

Back in the filing room, she could hear bits and pieces of Megan and her colleague chatting in the living room.

"Is she related?"

"... Oh, I see."

"... So hard to find these days..."

"...can she type?"

"...she didn't even finish."

"...how long has she...?"

"Oh well that's very nice of you."

"...Of course..."

A few hours into her filing, and aside from the skirt riding up every time she bent over, Elizabeth was feeling very comfortable in her new clothes. She'd found it a bit awkward to balance on the heels at first, but after a little while she didn't even notice. If she was honest with herself, she found the skirt and heels more and more comfortable, even a little exciting.

She knew some of the excitement she was feeling was coming from between her legs. She felt herself daydreaming while going through her mindless tasks. First about having more wild sex with her husband, and then about having wild sex with her husband while in her sister's office. The mental image of her husband bending her over Megan's desk in her sexy little number, ripping down her pantyhose and underwear, and fucking her was enough to convince her to take a few minutes of break time to calm down.

She felt much calmer after reaching down her skirt and jilling herself off after lunch.

Still in the restroom, Elizabeth felt her phone buzz after she was finished cumming and pulled it out of the tiny clutch she'd brought. It was Ms Hastings, her sister.

"Sorry about that this morning, the CFO is very formal, and if I'd let anything slip, neither of us would have heard the end of it."

Elizabeth's thumbs flew on the keys in response. "No problem. I heard a little of your conversation, what was she asking about?"

"Oh that. She wanted to know if we were related. I tried to convince her we weren't, but I think our resemblance is too close."

"What did you say I didn't finish? And that I couldn't type?"

"Oh yeah. Sorry. She wanted to know why you didn't have a computer and I just blurted it out."

"Ok that's bad enough. And the other thing?"

"I said you didn't finish college. Look, I had to, otherwise she'd be searching 'Betty McDaniels' with her friends at the school, and would find your whole history! You went to the same school!"

Elizabeth frowned. "So now I'm pretending I'm some dumb bimbo or something? This isn't what I wanted!"

"Look, don't give me that. You knew you were going to have to come up with a different backstory eventually, since you wanted to hide that we were sisters!"

Elizabeth wasn't sure about that. Hadn't it been Ms Hastings who'd suggested the whole thing? She couldn't remember now. "Fine, I guess."

"Anyway, we look way too similar. You need to do something to change your looks."

Elizabeth considered this. A soft white noise seemed to emanate from the phone as she thought of what to say back. "Like, how drastic?"

"I don't know, but a bottle of hair dye isn't going to cut it. Look, this is probably going to be a long term thing since I really need the help and I don't think Jeff is going to find a job anytime soon. Think about something that will really change your appearance. That's all."

Elizabeth frowned and put her phone away. She'd need to figure out what major change she needed to make if she was going to pull this off. It was beginning to get concerning how her sister was manipulating her so easily. She had always been the one in control before, and this job was reversing their roles so quickly and so completely that she felt a little light headed.

The phone rested contently in her hand.
