Betty gets some tits

As she stood in her bedroom and adjusted the garters holding up her thigh highs under her miniskirt, Elizabeth's internal voice piped up that maybe this whole thing was going a little far. In the past month, she had made the most drastic change to her appearance she could think of: a boob job. Not just any boob job, but a big one. She'd regretted it afterward, but in the office, talking to the doctor about what size she should get, Elizabeth hadn't felt entirely clearheaded.

She'd been feeling like that a lot lately. Something felt off.

Maybe it was the fact that she now thought of her little sister more as 'Ms. Hastings' than as Megan now.

Maybe it was the fact that she found herself wearing tighter and sexier clothes almost every single day now that Ms. Hastings had asked for her to work full time, 5 days a week, as her secretary. Her closet had filled up with brightly colored lace, tiny skirts, and showy tops.

Maybe it was the fact that after the first time she'd explained the whole situation to Jeff, that she was actually her own sister's secretary, and pretending to be a vapid bimbo at that, that he insisted on 'helping her' roleplay an airhead who couldn't even use a computer all the time around her own house.

No, she knew what was really bothering her inside. Last night after modeling her newest E cup lingerie, Jeff had been pounding into her from behind, bringing her to the crest of a delicious orgasm, when he'd slipped and called her Betty.

She came so hard she'd passed out.

She didn't know what disturbed her more about that: she'd instantly turned into a ball of electricity surrounding his cock at being called her alter-name by her husband, or that he'd immediately cum as well, and then repeated in her ear over and over as she faded to black "You're such a good fuck, Betty."

Just thinking about it now, she was getting wet all over again. What was this whole situation doing to her? Was it awakening some secret desire, secret fetish that she didn't realize she had? Did she deep down, want to be a stupid bimbo secretary, serving others and being treated like a slut?

I have to stop this, she resolved. I have to stop this before it goes any further and I do something I can't undo.

Jeff had left early that morning, and Elizabeth was alone in the house. She noticed it was already past her normal time to leave for work, and panicked. She was going to be late for work and Ms Hastings would be angry with her. She threw on a black mini skirt and pulled on her thigh high stockings and 4 inch heels, and raced out the door. She'd forgotten to put on her panties in her hurry to get out, but she reasoned it was more important to be on time than anything else.

Elizabeth raced into the office at 9:18am. She could hear Ms Hastings in the corner office, loudly yelling about something on the telephone, but she was having trouble discerning what.

She called out her greeting she did every day now, "Good morning Ma'am!" and reached for the ringing phone on her desk. She had been speaking like an airhead for a month now, and knew she sounded like a bimbo, but reasoned to herself that it was a part she had to play if no one was to find out that she was really Ms. Hastings' older sister. Today she was going to be trying to schedule Ms Hasting's business trip that was coming up. Quite the challenge without a computer.

Ms Hastings met her in the living room as she was getting set up. "Betty, what is the meaning of this?" she spat.

Elizabeth's eyes went wide, what was Ms. Hastings' talking about? "Uh, I.... don't under- understand..."

Ms. Hastings huffed. "You are late today by over an hour. I won't tolerate this from any of my staff, and I won't tolerate it from my dumb blonde secretary either. You have to be punished, girl."

Elizabeth felt shame, and stared at her sister's feet. She noticed her sister was wearing very high heels. They made her legs look very attractive.

"Like, I'm so sorry Ms Hastings. I like, fergot my alarm and stuff."

"Your attention to detail has gotten terrible as well." Ms Hastings said, knowing full well that it was she who instructed Elizabeth to act like an idiot. "You have a choice, girl. You can be punished here and now, or I can take it out of your pay. Choose quickly."

Elizabeth's mind raced. "I, I choose here, ma'am."

Ms. Hastings nodded curtly and marched to her office, not bothering to check if Elizabeth was following her. As soon as Elizabeth entered the office, Ms. Hastings grabbed her long blonde hair and bent her over her lap. Elizabeth flailed, "Like, what are you going to do to me?" She cried.

Without further explanation, Elizabeth felt her sister flip up her skirt and felt a hard "SLAP" on her exposed ass. "Ow! Sorry, Ms H, I'm like so sorry!" she cried out in pain.

"5 spankings for being late, another 5 for not wearing panties, you disgusting bimbo skank." her younger sister ordered.

SLAP!

SLAP!

SLAP, SLAP SLAP!

With each spanking, Elizabeth felt the final little pieces of her dignity and self respect crumble to dust.

SLAP!

SLAP!

She ceased wiggling and resisting in her sister's lap, any resolve to resist mometarily gone. She felt she deserved this now. She felt that she needed to be punished for disobeying her boss.

She felt wet.

SLAP!

SLAP!

Ms Hastings's hand had stopped spanking her, and had rested itself on her red and stinging ass. She shuddered a little, and felt her special phone buzzing, wedged into her bra, where it pressed against her new tits.

She waited there, for instructions to get up, when she felt the hand on her ass move down between her now tanned thighs to her wet slit. She moaned quietly as a single finger rubbed up and down, gently caressing her pussy as the pain from the spanking her little sister and boss had just given her began to fade.

"Are you going to obey me next time, girl?" Ms Hastings asked, a note of hesitancy in her voice.

Elizabeth couldn't comprehend what was happening, but managed to moan out "Yes, Ma'aaaaam"

Her boss kept rubbing, gently. "Tell me the truth girl, did you forget your panties on purpose? Was this just a ploy to entice me? Things lately have gotten confusing, I know you've been trying to... do something to me."

Elizabeth was sure she didn't know what her boss was talking about, "No, ma'am. I'm like, not doing anything. I just do the like, filing and stuff."

Elizabeth felt her mind let go a little more as her boss entered her slit with one tapered finger. "You sure you didn't want this? Do you want me to stop?"

Elizabeth moaned again, shuddering on her sister's lap. "No, don't stop!"

Her boss smiled and rubbed at her g-spot and clit. "Tell me what you are then, girl. Are you my sister? Or are you just Betty, my little bimbo slut secretary?"

Elizabeth struggled to answer. Her mind felt like a hurricane, and she felt the need to resist, if only to keep some small bit of sanity and sense of her real self. She felt another finger enter her and knew something was breaking. Something that wouldn't be fixable.

"I...."

A knock on the door interrupted the spell.

"I.... need to get back to work, ma'am." Elizabeth finally gurgled out.

"Oh, yes, quite. I need to get back to work, too. Get up girl, see to it and don't be late again." Ms Hastings ordered.

Elizabeth shuddered as she walked to the door, trying to smooth out her skirt and smelling like sex and sweat. She didn't know what happened, but she knew she'd kept what was left of herself. Why was she falling into this strange situation? Was she really about to let her younger sister finger fuck her after giving her a spanking? How could she even accept a spanking, let alone the incestual act she was letting her Sister-boss perform on her?
