My head was in a fog of disbelief, I barely remembered the bus ride home.

One of the guys on the team told me of a fucked up rumor. If it I didn’t need my football scholarship, I would’ve caved his face in. Instead I laughed it off and told him he was mistaken.

But you know how it is, once the idea burrows into your head, it festers and grows, and you’ll have to find out or it’ll drive you nuts.

I couldn’t do it during classes. If it was true and that’s a big if, I wouldn’t know how I’d react.

My heart was pounding hard against my chest as I fumbled to stick the keys into the door. I knew Kerry would be home.

I went straight to the living room and opened up my laptop.

I punched in a few keywords into the search engine. It shouldn’t be hard to find. He told me a girl who looked my step sister was on a pornography website.

I swallowed down a gulp as the webpage loaded up.

Oh fuck.

There was a girl being pounded hard. Her body shape, the hair, the face… It was without a doubt, my step-sister Kerry.

It had to be fake. I heard about this ‘deep fake’ shit on the internet. Some of the guys wanted to fuck with me.

I skipped forward, pulled it back. It must’ve been ten minutes, but it felt like forever. I knew it, from the ache burning in my heart, that it was her.

“Kerry!” I shouted. “Come here!”

I heard footfalls coming down the stairs. Kerry was in a pair of shorts shorts and a sweater. She looked at me with concern first, then her eyes went wide when she saw the laptop screen. “Oops, busted,” she said, poking her tongue out.

“Didn’t you say you got a job?! I didn’t expect it to be whoring yourself out like this! What would dad think?” I had to keep pushing, get to the bottom of this. Dad remarried years ago but that didn’t last. Instead he was left with his second wife’s daughter, my step sister.

Kerry sat down beside me, her tone was a lot calmer than I expected. “Did you watch it?”

“W-what on Earth are you talking about? Of course I didn’t!”

She raised an eyebrow. “So you don’t even know what I do, not really.”

Kerry pressed ‘play’ on the video.

“What are you doing?”

“I want you to watch me do my job.”

“I’m not going to watch my own step-sister do porn!”

“Oh? So you’d watch the video if I wasn’t your step-sister?” she sniggered.

She caught me in a trap.

“How did you get your hands on my video in the first place?”

“Uhh…”

“If you want to criticise what I do…” she said, snuggling against me as if we were casually watching a Netflix movie. “…then you have to watch it all the way through.”

My eyes went back to the screen. Kerry unmuted the video, her digital moans were loud and clear.

I’ll never accept that.

I get it, this is meant to be her job. But this is too much!

In the video, my sister’s head was arched back, her face a mask of pure ecstasy.

Shamed burned in my gut as my cock stirred to life.

This is fucking sick!

Have I failed as a brother? Kerry didn’t have a mother figure around and Dad worked two jobs. I got my shit together and did the best I could to look out for her.

To think she’d grow up turning into such an shameless woman!

I gritted my teeth, the asshole in the video was laughing, clearly enjoying Kerry’s body.

Fuck…

My sweet sister…

Is being fucked by a total stranger for cash!

A sharp bolt of pleasure shot through me as something touched my groin.

“Whats this?” Kerry mewled, her hands cupped the painful tent in my pants. “Are you getting aroused by your sister’s body?”

She expertly undid my buckle and zip before I could protest. Free, my cock flung out of it’s confines.

“You’re very big,” she gasped.

Before I could get away, she wrapped her fingers around my aching shaft, jerking it up and down in a tight, silky smooth motion.

“H-hey!” I cried out, swallowing down the tightness in my throat. “W-what do you think you are doing?! Stop!”

“I never seen your cock before. It’s so big.” She rasped. Her eyes were fixated on my cock.

“L-let me go.”

She obeyed.

I felt a strange momentary sense of relief and frustration at the same time.

Then she arched over and put her mouth over me. Pleasure washed through me as I felt her wet tongue swirl around my cockhead.

“Look, no hands,” she giggled.

“W-what are you doing?” I groaned out.

“Jeez big bro, you know what I’m doing.”

The room was filled with the lewd sounds of her mouth schlucking thick drool all over my cock, saliva running down my shaft.

“…You’re getting sucked off by your naughty sister.”

Oh God. How did it turn out like this?

This is bad. I gripped my hands tight against the sofa as my sister’s mouth attacked my cock.

My heart pounded hard against my ribcage. I had to push her away, but it felt so fucking wrong and so hot at the same time.

She looked up at me, flashing me a mischievous look.

I was in heaven, my cock disappeared deeper into Kerry’s mouth, I felt the tight wet ridged walls of her throat milking my crown. Aghh! She’s taking it so deep! O-oh shit!

At this rate I’m going to cum in my step sister’s throat!

“K-Kerry! Okay I get it! You’re serious about your job, please stop!”

“Sorry, no can do. As a pro I have to…” she giggled as she eased my cock out of her mouth, then running her tongue up my shaft, lapping up spit and precum. “… properly make you cum.”

“This isn’t the time to show off your professionalism!”

If I don’t force her to stop now, it’ll be bad and yet…

And yet…

I felt my balls tighten with need.

“Oh God…” I groaned out.

“Mmm, what a nice moan, Big Brother.” she said, running her lips over my head and teasing my glans with her tongue. “Does your sister’s mouth feel that good?”

“Stop saying such things…” I gasped.

But it did. It so fucking did. Kerry blossomed into a beautiful young woman and I felt bad for lusting after her 18 year old body. And now she was doing this… It was a sordid dream come t
