I kept grinding into my sister. I hadn’t gotten off yet, but I was close.
“OH!” Darcy cried out. She arched her crotch upward and I felt my dick slide back. Suddenly, my very bare cockhead was resting right at my sister’s very bare pussy. I could fall forward a centimeter and be sheathed in her snatch.
Darcy whispered in my ear. “Put it in.”
What?
I stopped in place.
“Put it in me. Please,” Darcy said. She looked at me with wide, wanting eyes.
The reality of what we were doing – who I was with – rushed over me like ice water. I was humping my sister. My sibling wanted me to have sex. My dick shriveled down to nothing. I rolled off to the side.
Darcy seemed to immediately see the change in me. She hugged me close.
“We can’t do that,” I said, “That’s sex. You said we can’t have sex.”
“It’s alright,” Darcy said, “I want it real bad and I know you do, too.”
“Are you even? I mean, do you take the pill? Or whatever?”
Darcy bit her lip. “I trust you,” she said quietly.
“We can’t do that,” I said, “You said it was wrong, Darcy. It’s wrong. We shouldn’t. Fuck, we’re not supposed to be doing any of this.”
My sister lay back shellshocked. I grabbed my clothes and put them on. I felt icky, literally gross. I went upstairs and got in the shower. All the things we’d done came racing back to me. I couldn’t get them to go away.
When I got out of the bathroom, Darcy was waiting for me. She was fully dressed. “Ethan, I’m sorry,” she said. “I got carried away in the moment. You weren’t ready for…”
“Ready? How could I ever be ready for that?”
Darcy winced. I’d clearly hurt her feelings. She took a deep breath. I saw her face go stony. “You sure seemed ready for all that other stuff,” Darcy said. “You’re supposed to be different. But you’re like every other boy. You only care if you get yours.”
“Darcy, I…” My sister’s sudden change of tone surprised me. I hadn’t expected her to fire back, and now I found myself unprepared. “That’s not true,” I said. “I love making you… Well. You know. It’s amazing.”
“But it’s wrong,” Darcy said.
“No! Well, yes. I don’t know. Fuck,” I said.
Darcy took a deep breath. “OK, I know you’re new to all this stuff and it can be scary,” she said, “But that’s why we’re doing it. So you can be ready for a real girlfriend. Like Victoria from the lingerie store. She’s going to expect you to take care of her and I’m showing you how. I’ll take the lumps for now, but I expect you to learn.”
I nodded. “I’m sorry, Darcy.”
“Me too,” my sister said. She kissed me on the forehead, then stepped away. We searched each other’s eyes for a moment.
I heard the front door open as my parents came home. At least we’re both dressed, I thought. Darcy walked past me and into her bedroom, shutting the door behind her.
That night, after dinner, Darcy came into my room like always. We acted like it was all the same, but it wasn’t. She gave me what I can only describe as a cursory handjob, then stood up stiffly. I offered to return the favor, but she waved me off.
“I have to get up early for work,” Darcy said, “So I probably won’t have time to help you tomorrow morning.”
“Tomorrow’s Sunday,” I said.
“I know. It’s some emergency thing,” Darcy said, “I’ll be back as soon as I can.”
I felt a strange sadness well up in my chest as my sister switched off the light and left my bedroom.

The next morning, I woke up to my cell phone screaming at me. I picked it up and saw that my sister was calling.
“Ethan, thank God,” Darcy said when I picked up. “I have a serious problem.”
“What’s wrong?” I asked, groggy. My first thought was that she’d been in an accident and it made me almost nauseous with worry.
“My work computer crashed, and it wiped half my hard drive. The techs say they can get it back, but I’ve got a meeting in five and I can’t wait that long. I need the Anselmo Case file. It’s in my backup storage on the laptop in my bedroom.”
I popped out of bed and raced over to Darcy’s room. I opened the door, phone in my hand, and went straight to her desk.
“There should be a thumb drive in the laptop, you see it?”
“You want me to bring it over to you?” I asked, “I could probably borrow Mom’s car.”
“Not enough time,” Darcy said, “Just turn on the laptop.” She gave me her passcode and had me go into her e-mail and send her the file.
“Thanks, bro. You’re a lifesaver,” Darcy said when the message came through, then hung up. I sat back in her chair, exhausted. I’d just gotten up and I already felt like going back to bed. If that was Darcy’s job on a Sunday, I was happy to be in the mailroom.
I looked at her computer screen, dumbly. It had the standard green field and blue sky that came with Windows. The desktop was almost completely clear. A few programs, the usual icons, and one folder dragged to the middle. It was labeled ‘E.’
I told myself to shut down the computer, but my curiosity got the better of me. After all, the folder had my name on it. Right?
I opened the file. My eyes went wide.

I waited until Darcy came home. It was another super late night for her, and she didn’t show up till well after my parents had gone to bed. I saw her headlights scan down our sleepy street. Heard the door as she came inside. I stayed still, in the dark, sitting right at my sister’s laptop.
Darcy came upstairs. I heard her check my bedroom, then she opened her own door. She saw me sitting in her chair and jumped.
“Sorry, E, I didn’t expect you in here,” she said.
I didn’t reply. I took the laptop off the desk and showed it to her. My sister looked confused, then certainty filled her face. Anger and a bit of fear.
“You went through my private stuff,” she said.
“It was an accident,” I lied, “When you asked me to go into your email, I opened it by mistake.”
My sister stayed standing, staring at the laptop screen. I knew what she was looking at. I’d spent all day going through it myself.
The ‘E’ folder was porn. Lots and lots and lots of porn, enough to dwarf even my own comprehensive collection. Unlike mine, though – which had a variety of different fetishes and themes to fit my many different horny teenaged moods – my sister’s smut was centered around one specific thing: incest. Brother/sister incest.
She had videos of supposed siblings, movies, captioned pictures, audio recordings, short stories, full novels – all of it. Any kind of porn you could imagine, she had it, and it all featured siblings doing the one thing they’re not supposed to do together. The very thing I’d been doing with Darcy.
“How long?” I asked.
“What?” Darcy asked absently.
“How long have you had a thing for me?”
“I don’t have ‘a thing’ for you, Ethan,” Darcy said, hotly.
“This whole time you’ve been acting like it was a mistake, or luck, or you taking care of me,” I said, “But that’s not it at all, is it? This has been about you fulfilling your weird fantasies.”
Darcy didn’t say anything. She was wearing a pink and white whorled sleeveless dress. Professional for her big meeting that morning, I supposed. The laptop was the only light in the room.
“So, you’ve, like, always had a crush on me,” I said.
“No, Ethan,” Darcy said, “This isn’t about you. I mean, not really.”
I gave her a dubious look.
