Every step sister fantasy starts the same way. With a girl who knows exactly what she is doing and a boy who is trying so hard to be good.

I am Bailey. Twenty. And yeah, I am the reason you cannot look Dad in the eye at dinner anymore. This step sister fantasy is the story of how I stopped pretending I did not notice you noticing me. Let me tell you about last weekend.

Your Step Sister Fantasy Begins When the Parents Leave

Mom and Dad left Friday night. Some anniversary thing, gone until Sunday. The second the car pulled out of the driveway, I was on your bed. Wearing one of your old t shirts and absolutely nothing else. Hair still wet from the shower.

You walked in and froze. Bailey, what are you doing in my room?

Bored, I said. Horny. And I have been thinking about what you would feel like inside me since Christmas.

You tried to leave. You really did. You got as far as the door before I said the thing that stopped you. I know you watch me, step bro. I have always known.

How a Step Sister Fantasy Gets Filthy

I have known for months. Since I started forgetting to wear pants around the house. Since I bent over to grab the remote that one time. Since I started showering with the door cracked just enough. I have seen you adjust yourself. I have heard you through the wall.

And I have been touching myself thinking about you the whole time.

I stood up, slow, and I let that t shirt ride up. You want to keep pretending? I asked. Or do you want to finally do something about it?

You crossed the room in about half a second. That is when this step sister fantasy stopped being a fantasy.

I called you step bro the whole time. I am not going to lie, it made everything filthier. Is this what you think about in the shower, step bro? I whispered while you were inside me. Is this what you hear through the wall?

The Middle of Every Step Sister Fantasy Is the Best Part

We did not leave your bed for hours. I rode you until my legs gave out. Then you flipped me over and took over, and I loved that, I loved feeling you lose control, feeling you finally take what you have been wanting for months.

Pull my hair, I told you. Do not be gentle. You have waited long enough to be gentle.

You were not gentle. You were perfect. Desperate and rough and exactly what I needed. I screamed into your pillow, because even with the parents gone, old habits die hard, and you covered my mouth with your hand, and that somehow made it even hotter.

After, we lay there tangled in your sheets, and I traced patterns on your chest, and I said, We are so bad.

The worst, you agreed, grinning.

Worth it, I said.

Why This Step Sister Fantasy Never Really Ends

Because we still live in the same house, step bro. Because every dinner is a performance now. Because I still forget to wear pants, except now I do it on purpose, and now you know I do it on purpose, and the look on your face when Dad asks you to pass the potatoes is my favorite thing in the world.

We have a secret. It is delicious. It is ours. And every time Mom and Dad go out, even just for groceries, you know exactly where to find me.
