We were both naked on the bed when Lena grabbed her laptop. "Let's do it," she said, spreading her legs so I could see how wet her cunt already was. "Write the story about last night and post it on Facebook. Right now."
My cock twitched hard at the idea. We'd talked about it before, but this time she meant it. I slid two fingers into her pussy while she started typing. "Fuck, your cunt is soaked just thinking about strangers reading this," I told her. She moaned and typed faster, describing how I'd bent her over the kitchen table and pounded her ass until she screamed.
Lena read the first paragraph out loud. "He grabbed my hips and shoved his thick cock straight into my tight hole…" Her voice got breathy. I pushed her onto her back and buried my face between her thighs, licking her clit while she kept typing with shaky fingers. She tasted like pure need. Every few sentences she stopped to grind against my tongue and tell me to add more details.
"Make it dirtier," she ordered. "Say how I begged for your cum in my ass." I sucked her clit harder and she came on my face, legs shaking, but she didn't stop typing. The story grew longer, every filthy thing we'd done the night before laid out in plain words.

When she hit post on the fake account we'd made, her pussy clenched around my fingers again.
We watched the screen together. The story went up. Likes started coming in fast, comments popping up from strangers saying how hard it made them. Lena wrapped her hand around my cock and stroked it rough. "They're all reading about you fucking me like a whore," she whispered. "Think they're jerking off to it right now?"
I flipped her onto her stomach, yanked her hips up, and slammed my cock into her cunt in one thrust. She was dripping. I fucked her hard while she refreshed the page, reading comments out loud between gasps. "One guy says he wants to watch you stretch my ass next time," she panted. I pulled out and pressed the head of my dick against her asshole. She pushed back and took me deep, groaning as I bottomed out.
We kept the laptop open beside us. Every new notification made her clench tighter around my cock. I reached under her and rubbed her clit fast, telling her how many people were probably stroking themselves to our story. She came again, ass squeezing me, and I followed right after, pumping thick loads into her while she typed one more filthy line: "He just filled my ass while we watched you all read this."
We lay there catching our breath, still connected, scrolling through the reactions. More comments, more people turned on by exactly what we'd done. Lena smiled and started writing the next part, already planning what we'd post tomorrow. My cock was getting hard again inside her just from the thought.
