Yes

You decide to take a chance.

“Rebecca, would you come with me to my room for a minute? There’s something I need to talk to you about.”

“Hmm, why not.” replies Rebecca, in a blasé attitude.

The two of you enter your bedroom and you promptly shut the door. “Is Clive asleep?”

“Yeah, why?” asks Rebecca.

“I just needed to know... because this whole fucked up day... well... I think it’s because of him.” you say as you begin to break down, sitting on the edge of the bed.

“I don’t know how, but he is using some kind of mind control over me... and dad too. He made me say all of those things about him being more of a man than me, made me act like a sissy and made you all believe that’s what I wanted. Honest, you have to believe me sis! It was him... it has to be. I don’t understand how the fuck he’s doing it, but you must know that I would NEVER say or do any of the things he made me do!”

You begin to cry a little as your sister takes a seat next to you, placing her arm around your shoulder, pulling you in for a hug.

“Now now little bro... it’s ok. I believe you.”

“Y-you do?!” you ask, feeling surprised yet relieved.

“Well of course, I know you’d never want to be a sissy. I mean, you’re always checking out my friends, not to mention me and mom. Like, do you have no limit to how perverse you are...?” she says with a giggle.

You’re not quite sure what to think about her statement.

“But then again... I guess being a pervert runs in the family. I’ve been having so much... fun.” she says, with a wicked grin forming on her face. The way she paused right before saying “fun”...

And just like that, it hits you. It cuts so deep your jaw practically drops to the flaw. “It can’t be...” you say as your worst nightmare becomes somehow worser still. “It was you!”

It all makes sense now... the reason why you couldn’t control yourself when you left Clive in the living room with your dad. Every time Rebecca was near you...

“That’s right, Zack.” admits Rebecca. “It took you sooo damn long to figure it out, but at least now the real fun can begin!”

“Rebecca... I can’t believe it was you... all along! I thought...”

“Of course... did you really think it was Clive pulling the strings?” Rebecca laughs, “HA! That egg-brain is all muscle - not much of an intellectual like you and me, am I right, sissy Zoe?”

Still in shock, you just sit there staring at Rebecca. “How could she do this to me... her own brother. Wait... HOW is she doing this exactly?!” you ask yourself as you begin to push per off you.

She frowns and says, “You’re probably wondering how this is all possible - how I’m controlling your actions, making you say and do what I want you to... right?” your sister says, still smiling.
