**Cain**

Something was going on with Aven and I intended to find out what. Grabbing her phone was easy, unlocking her face-lock was easier. I need to teach her about account security. But then messages popped up from an app I didn’t expect. Her social media was a flood of lewd comments under the avatar of the blond chick. The fuck? I stared at the username and the photos. In a draft reply, a video was playing. Aven was dolled up in a blond wig with no glasses and looked like a completely different person. Wearing a short red dress, she was fashing her bare shaved pussy for views. Fuck.

I closed her phone fast.

Clearly, this wasn’t meant for me. If she needed money that badly, I could’ve given her the cash. Then my mind turned. If she needed dick, I could’ve given her that too.

What are you thinking? She’s your step-sister! Disgusted with myself, I walked over to her room and threw her phone on her bed. The room smelled of her sweetness.

It’s shameful how my body responded to just her smell. I had told her I hated the sweet bath bombs she used in our shared tub, but really it’s because every time she used it I could taste it through my door.

I’d knew she was naked, rubbing down, soap spreading across her lush boobs, between her thighs, and she’s touching herself in all those places siblings were forbidden to think about.

How often have I wanted to feel Aven’s soft skin on mine? Ever since highschool I’ve dreamt of my adopted younger sister, as wrong as it was. But what she’s doing is worse.

I was hesitating over the decision to look up her account when Aven charged through my door asking for her phone. Glaring behind her glasses and sweats, she’s always such a tom-boy. It was hard to imagine her as the coy, blushing blond in the video.

She slammed the door behind her and I groaned. Aven’s always so short sighted, literally. What if someone connected her account to the real Aven? It could hurt her future.

I looked her up and joined her followers. Damn, that’s a lot of posts. What worried me were the ones she had being an exhibitionist in public. Shit. Knowing she went downstairs for the movie, I went over to her room and rummaged through her tote bag, and sure enough, I found evidence of her breaking the law: masturbating in a dressing room. What were you thinking?

I deleted the footage, but worried there’d be more. Checking her online account, there was an empty classroom, a park. Jesus Aven. I quickly got rid of those and hoped none of her fans were industrious enough to download them. All the while, my growing bulge strained against my pants.

Ten years. I’d been good at ignoring Aven, pretending like she was just another friend, my step-sister—out of bounds.

But now, Aven looked like a cute little minx squeezing, teasing, presenting her boobs for all to see. “Tell me what you want to do to me.” My erection darkened, remembering why I hadn’t moved out, even though I was perfectly capable.

Next clip, “I want a boyfriend that’ll let me lick him every day.” Aven said before sucking on a dildo like it was the tastiest thing she’s ever had, while practicing her deep throating.

My dick pressed against my pants, and I needed to let it bob free. There were nights where I’d hear her through the door of the bathroom moaning to satisfy herself and how it’d drive my own shameful urge to join her, but didn’t. I never showed that I’d been infected with depraved throughs of her.

Then, it was Aven staring at the camera declaring in a pitched voice, “I’m so lonely, help fill me up”, as she gave the audience a full view of her cute dark slit. My desire for her formed into wet droplets, soaking my boxers in pre-cum, weeping to be in her swollen folds. How many times I’d listened through the closed door, pacing my hand with her moans, till we were cumming together.

Then there was a scene where she’s dressed as a slutty school girl. Her top cut short, it barely covered her nipples, letting her under-boob hang lose. “Big sister, help me with my homework.” She declared to this other girl.

Aven used to come into my room all the time, asking me questions about classes and I’d pretend that I was annoyed, but I always wanted her to stay. What would it be like to have her sit on my lap wiggling her ass like she was doing now with this other chick. “Please help. I’ll do anything you ask.”

Bimbo Aven’s rubbing her insane cleavage up and down the back of this other woman and I wanted to be there. Then the other girl guided her lower, and I’m watching as my little step-sister licks, her tongue moving up and down that pink clit and I move my hand up and down my shaft, realizing I wanted to touch Aven in more ways than as friends, as family. I wanted to touch her like she’s mine.

And I’m undone. Fuck, it’s too hot.

Now I have the added shame that I just came watching Aven’s porn. I wished it was me with her. Wanting to have her scream my name and look into my eyes as I made her mine.

What’s wrong with me?

My heart shivered. If Aven knew the effect she had on me, she’d run screaming for the hills.

I sighed, head slackened back, grabbed for tissue, cleaned myself up halfway decent, and walked to the bathroom for a cold shower.

That’s when I heard it, the unmistakable little moans coming through the door.

In post nut clarity, I should’ve been able to stop myself, but it felt like a dream as I pushed open her door. Aven’s eyes were closed, hand rubbing underneath her sweat pants and…Did she just say my name?

I watched as her body tensed in orgasm and blood pounded loudly into my brain, now echoing the most depraved thoughts I’d imagined earlier. There’s a chance she’d want the same. That she’d want to be mine. My heart pounded as if it wanted to leap from my chest as an offering at her feet.

**Aven**

“Cain! What the hell!” I pulled down my shirt, grabbed my pillow, and threw it at his head.

Except he just batted it away before walking over and sitting at the edge of my bed. I made myself smaller.

“I should ask you the same thing.” He said, handing me back my camera. I jerked it from his hand, trying to ignore the cute crease between his brows when he’s worried about me.

“Being slutty is one thing, but public indecency could still get you jailed. Especially if you had recorded evidence. Did you think of that?” He’s scolding me but my eyes were on the cum stained boxers he hadn’t had time to clean yet. I licked my lips.

“Aven, are you listening?” He asked. I knew he was being a good big brother, but he’s also sitting at the edge of my bed, after watching me masturbate thinking of him.

“What do you want me to do? It’s the fastest way to make money.” I scoffed, turning on the camera feed. Empty. He’s seen it. While I was watching the family film downstairs, he had a good 90 plus minutes with my amateur porn stash, including my OF back log. Did he like it?

I blushed. Stop thinking that!

“Pull your OF account.” He said simply, his hand splayed, bracing on my bed, knuckles tense. “I’ll give you the money as long as your account’s shut down.” I noticed the other thing tensing between his legs.

He did like it.

“You’re going to pay me…” I put the camera aside and moved closer. “For my OF account.” I could see his growing need, and I wondered how far I could push it. Will he back down first? Because it was wrong how much we’re clearly attracted to each other. “You know I don’t just get money from my fans, right?” He held his ground as I crawled closer, till my soft breasts were pressed against the side of his arm.

“I also get a fair amount of…pleasure.” I whispered in his ear and he blushed so hard his face was pink. “Are you man enough to take care of me?”

Faster than I could react, he grunted, and I fell. He’d pinned me to my mattress. In his eyes were guilt and confusion echoing mine. He was battling against the animal inside him, the screaming of his thickened cock that wanted nothing more than to fuck me, and I was so turned on I burned.

“Yes, I’ll take care of you.” His mouth was on mine and it shouldn’t have tasted so good. The way he searched inside me. So wrong, so cruel, so possessive. His free hand grabbed at my breasts and thighs, while his tongue groped every part of my mouth. Twisting the wrongness into breathless paradise.
