My OnlyFans sister needed a bigger cock for anal... so she used mine PART 2!

The anal clip had been up for four days, and I had watched the view count like a guilty man checks a door. Sienna texted me the screenshot at midnight. Comments under it were not subtle. *Same guy in her pussy next. Don’t cut. Ass to pussy. What a monster cock! What’s his porn name?* I locked the phone and still saw it when I shut my eyes. I had already been inside my sister’s ass. Wanting the rest of it did not make it less wrong. It made it worse, and worse still felt good.

Mom was on the late shift again. I was on the couch pretending to scroll when Sienna came out of her room in the cropped tee and those useless shorts, phone in her hand, smug in a way that meant the money had cleared.

“You’re welcome,” she said.

“I didn’t thank you.”

“You should. They love you. Well, they love your cock. They don’t know it’s my brother’s.” She dropped onto my lap like the couch was full. Ass on my thighs, back against my chest, already grinding before I could shove her off. I was half hard from the comments. She finished the job in about ten seconds, rolling her hips over the sweats, slow, mean and sexy.

“*Sienna*.”

“Doomscroll later.” She held the phone up in front of both of us. “Listen. ‘Whoever that was needs to put it in her pussy right after. I paid for the stretch.’” She scrolled. “‘Ass to pussy or I’m unsubbing.’ That’s twelve of those. Same sentence.”

“Get off.”

“You’re hard under me and telling me to get off. Pick one.” She ground down again. I felt her wet pussy through the shorts. My hands had landed on her waist and had not left.

“You’re dirty.”

“I’m employed.” She tipped her head back against my shoulder. “What do you think I want?”

“I know what you want.”

“Say it.”

“Ass to pussy. You want me to fuck your ass and then your pussy. On camera obviously.”

“Look at you, literate.” She laughed. “You pull out of my ass and go straight in. They want to see it shine.”

“No.”

“Cole.”

“That’s too much. The first one was already—” I had to stop because she rolled her hips and my voice broke. “You’re my sister. I came in your ass. We’re not filming a tour.”

“You liked coming in my ass.” She reached back and palmed me through the sweats, squeezed once. “You followed me down the hall. Don’t do the speech.”

She opened her page. A folder. Her on the pink rug with a toy, then another, then a video she had not posted: a friend of hers, face off, some guy pulling out of her ass and pushing into her pussy in the same stroke. The sound was wet. Sienna held the phone steady and kept grinding on me like the video was a manual.

“See? Not hard. She takes it. I can take it better. You barely fit in my ass. Imagine their faces when you put that in my pussy after.”

“Turn it off.”

“You’re throbbing.” She was right. I was so hard it hurt, my sister in my lap, her ass working me through two layers of cotton, a video of the exact thing she was asking for playing six inches from my face. I knew it was wrong. The wrong was the part I couldn’t put down.

“If Mom sees a second video—”

“Faces off. Same as last time. She already knows I film. She doesn’t know it’s you unless you say your name, or show her your cock.” She paused the clip on the switch, ass to pussy, the girl’s hole still open. “Yes or no.”

She ground down one more time, slow enough that I felt the whole shape of her and her two globes pressing down onto my hardon. My hands tightened on her hips. I should have told her to get a different guy. I didn’t.

“Fine,” I said. “One take.”

She smiled against my jaw, smug and warm. “You’re the best.”

\*\*\*\*\*

Her room was already a set. The ring light made the pink rug look cheaper than it was. She set her phone on the tripod, tilted down so the frame would catch her ass and not our faces. Sienna checked the angle, hit record, and looked back over her shoulder.

“Shorts off. Lube first. And don’t rush the switch. That’s the whole video.”

I shoved the sweats down. She knelt and peeled her shorts and underwear off in one motion. The cropped tee stayed on. Everything else was the shot. Sienna was still the problem she had been for a year: mean mouth, blonde hair stuck to her neck and tits heavy in the tee when she leaned forward. The camera did not care about that, for now. It was all about her ass and my big cock. She reached back and spread herself, and her ass filled her hands. Bleached pale where a bikini never sat, smooth, round, the cheeks full enough to spill around her fingers. The hole was small and pink, already a little shiny from whatever she had done before she talked me into another video. Under it, her pussy was wetter than her voice. Flushed lips, a thin gleam on the inner skin, and the smell of her stronger once she opened her knees. My sister, on her rug, holding herself open for a lens.

“Lube,” she said. “A lot. You know what you did to me last time.”

I pumped until it dripped and slowly spread it over those pale cheeks, making them shine. My thumb circled the tight rim until it winked. One finger, which she took and exhaled. The second made her moan. I worked her open and watched the stretch, the way her hole clung to my knuckles and tried to close when I pulled them out. Lube ran down toward her pussy. I caught it with two fingers and rubbed it over her, not in, just slick.

Before I lined up, I leaned down and kissed her there. Open mouth, right on the heat of her pussy, slow enough that she jerked and almost broke the pose.

“Hey—”

“Quiet.”

Then I set the head of my cock against her pussy and pushed in. She was hot. That was the only clean thought. Hotter than my hand, wetter than the lube, a tight slide that took the head, then the inch after, then the rest, until I was buried in my sister and her pussy was fluttering around the base. I stayed there. I could feel her heartbeat. I could feel how easy she got once she stopped bracing. It was wrong but stupidly good.

“Fuck. That’s … don’t get comfortable. They didn’t pay for this part.”

I pulled out. She was shiny on me from root to tip. I set the head against her ass and pressed. The rim fought. Pale skin went taut around the crown. I pushed again and it popped through. She moaned out into the rug, real. I fed her an inch, then another. Lube squeezed out in a bright ring every time I eased back. Halfway she was shaking, fingers dug into the rug. Three-quarters she pushed onto me herself. I sank the rest. Hips flush to that bleached ass. Her hole stretched wide around me, gripping, fluttering, nothing like the melt of her pussy and better for it.

“Fuck me,” she said, voice turned up for the mic. “They want to see it. Then the switch.”

I fucked her ass in short strokes so the camera could catch the drag. Her rim clung to me on every pull, a pink ring that did not want to let go, then swallowed me when I pushed back in. Her cheeks jiggled. The tee rode up. I held her hips and watched myself disappear into my little sister, and the taboo sat in my stomach and made me harder. She did not come. She took it, breath breaking, talking to the lens about how thick it was, how she could feel it in her stomach. A dozen strokes. Then she reached back and tapped my wrist.

“Now. Out and in.”

I pulled out of her ass. Her hole stayed open a second, pink, used and shiny. I lined up with her pussy and pushed back in raw, still wet from her ass. The heat hit again. She clenched, then gave, and I slid to the base in one stroke. Ass to pussy. I felt the difference in the same breath: her ass had gripped like a fist, her pussy opened and melted around me, hotter, slicker, a wet sound the mic was definitely getting. Both were my sister. I groaned and hated how good the second hole felt after the first.

I gave her longer strokes. Almost out, so the head tugged at her, then in to the hilt. Her tits swung in the tee. Her ass moved every time I bottomed out. She held the pose and let me use her. She kept pushing back so the camera would not lose the angle. I was close. The switch had done it. The heat of her pussy after her ass had done it.

“I’m gonna come so hard.”

“Pussy first,” she said. “Then finish where they can see it.”

I slammed into her pussy and came, hard, pulse after pulse, filling my sister while she stayed up on her knees and took it. I pulled out while I was still spilling. Cum striped those bleached cheeks, thick white across the pale skin, one line sliding toward her hole. I pushed back into her ass before it ended. The last pulses went in there, grinding against her, emptying what was left into the tighter heat, her rim stretched around me while I shook.

I stayed buried a second. Then I eased out. She shoved the phone into my hand.

“Film it. Both. Slow.”

I took it. Her pussy was open and pink, my cum leaking out of her onto the rug in a heavy line. Her ass was open too, a second creampie welling up and running down to meet the first, mess from both holes on her cheeks, on her thighs, stringing between them. I held the phone steady until the worst of it slid free.

I stopped the recording. She looked back, flushed.

She kissed me quickly, still on her knees. “Thank you,” she said with a grin. “Don’t watch the comments tonight unless you want to get hard about it again.”

She took the phone and smiled at the thumbnail like the wrong part had already been cropped out.
