Stepbro Sissification

You won’t believe what I read in my stepbro’s diary! First, you’re probably wondering why I read his diary anyway. Well, his bedroom door was open and he had the diary wide open on his bed. I couldn’t help myself. I’m glad I did read it though because he’s been VERY NAUGHTY. It turns out he’s been wearing my panties when I’m out of the house! Apparently, he also sneaks into my bedroom when I’m in the shower to wear them too. Sounds like he enjoys a bit of danger.

As you can imagine, I was not happy upon reading this! But I decided I was going to surprise him one day. I wanted to catch him in the act of wearing my panties. So I chose a day that I knew only the two of us would be home for a while. My stepbro had no idea what was about to happen. I was ready to get back at him!

So I came home early, and quietly, so I could sneak up on him.

As quiet as a mouse, I walked down the hallway toward his bedroom. The door was cracked open so I was able to peek inside. And what do you know! He’s standing there looking at himself in the mirror wearing MY panties. I couldn’t help but giggle, inevitably giving myself away.

He jumped back as soon as he heard my voice. Completely startled, he asked me what I was doing at home so early. Well, I told him that I should be the one asking questions. I could hear him make an audible gulp. He was totally nervous and blushing, of course. I walked into his room, closing the door behind me. I had my backpack with me that held some interesting clothing items that I brought just for him. He didn’t know this yet, though. In fact, he had no idea what I was going to make him do next.

When I looked down to see the front of the panties on him, I noticed a large wet spot. His clit was hard, but it fit perfectly underneath the soft fabric. I looked up at him in disgust. To be honest, I didn’t mind so much that he was in panties. It’s the fact that he was doing this behind my back, using my stuff without permission! That’s why I needed to fully sissify him. I do mean total sissification from head to toe.

As I told him my plan, he looked at me wide-eyed and begged me not to tell anyone.

Well, I laughed and told him that he better comply or people will be finding out about this. I wasn’t fucking around. Then I unzipped my backpack and took out stockings, a garter belt, and a lacy bra with matching panties. Oh, and a pair of high heels too! It was everything he needed to be turned into a real sissy.

Of course, he was trying to wriggle his way out of this. But I reminded him that I am just a phone call away from shattering his entire world. He then started to follow my orders. So I then helped him get into every piece of the lingerie set. He watched himself in the mirror as I made sure everything was in its right place. Guess what? His clitty never got soft! In fact, it was leaking like crazy when I put the lacy panties over it. The last thing I helped him get into was the high heels. I giggled and told him I should have done this sissification thing a long time ago!

He was standing there in front of the mirror. I walked up behind him, asking how he felt. Surprisingly, or maybe not so surprising, he said he felt pretty. Even though he was still embarrassed. I hugged him from behind while saying that we could go shopping together. That way he could pick out his own panties and things. Without having to use mine!

He turned around to face me and gave me a big hug. Telling me that I was the best stepsis ever. How funny is that? I wasn’t expecting it to turn out this way, but hey, I’m happy for my sissy stepbro!
