[Fiction] Blackmailing My Step Sister Into Humilation

[Truckernaut42]

I'll keep this brief, because I'm sure you all want to get to the good stuff, right? Really simple. My parents divorced when I was young and when my mom remarried, her new husband had a daughter named Michelle, who was 2 years younger than me. She was a brat from the start and I was always stuck with taking care of her, the excuse being how hard the divorce was for her, blah blah blah. Fast forward to her 16th birthday. I'm 18, and our parents go away for the weekend. It was agreed Michelle could have a few friends over and just a few. I get back from work to find out she had a massive party and all her shitty high school friends trashed the house. Michelle got drunk and passed out so I was stuck with the mess. In the morning, she begged me to help her clean up before our parents came home and not to tell them. I knew this would give me leverage against her so I agreed.

The day came so soon too, when she asked for a ride to go clothes shopping for new pants, and, from what I heard her whisper to my Mother, underwear.

Let's talk about my step sister. She's short, brown hair in dreadlocks because she's going through some phase. She has small breasts but I never can really tell because she doesn't wear form fitting clothes. But I can tell she has a big bum. I've admired her body a few times, she is only my STEP sister after all, so it's not incest, right? Anyways so my mother comes to my room to ask me to take Michelle to the mall.

"Why?"
"Because I said so that's why. You need to look after her, she's your sister."
"Not really Mom."
"Look, Jacob" (yes that's my name, in case you were wondering) "Things have been hard for her..."
"Since the divorce, which was how many fucking years ago?"
"Jacob! Language! You do not talk to me like that. You take your sister shopping or I'll take your car away."
"You can't do that!"
"Yes I can. You forget I still have the bill of sale. You can bike to work."
"Fine, I'll take her." I grumbled under my breath.

"No mom... It's okay he doesn't have to..." Michelle nervously said.
"No Michelle he is your big brother and he is going to."

Part of me wondered if Michelle knew what was going to happen that day, or if she just didn't want to go pantie shopping with her step brother.

We didn't talk much in the car.

"I'm sick of having to look after you. I should tell Mom about that fucking party!"
"Please don't! I'll do anything!"

It was at that moment I realized, we were going clothes shopping. I smiled.

"What?" she inquired
"Here's the deal sis. We'll go shopping for clothes. But you're going to wear a few things I pick out, no matter what. Got it?"
"Oh, um okay?"

She had no idea how much fun we were going to have today.
