I told her that in high school a good friend once asked to suck my cock so she could practice before trying it on her boyfriend later that night. It was a drunk story I told her late one night, and I had almost forgotten I shared it until she climbed into bed with that look on her face that I love so well.
“You remember that thing about a practice blowjob?” she asked, kneeling over me and licking her lips.
“Of course I do. It was a fucking fantastic afternoon, and after the party, my friend kissed me on the lips telling me her boyfriend had loved how good she was.”
“Yeah, that one,” she sighed, reaching one hand down to my jeans. “Can we maybe try it out? But with other things?”
We played a few different games, but I was fairly certain I knew which one she meant. I rolled her to one side and pushed her hair behind an ear gently. I slide the strap of her shirt and bra down as she looked into my eyes with a question. I whispered that it was okay. I assured her everything would be alright as long as we were quiet and didn’t tell.
“But we shouldn’t,” she sighed.
“I just want to help,” I told her, taking her hand and placing it on my growing cock. “It doesn’t matter that you’re my sister, it only matters that I’m here, and you need to practice. You want to make him happy, don’t you?”
“But what if someone finds out?” she asked, not taking her hand away as I gently kissed her neck and chin.
“You’re not going to tell anyone, are you?” I asked. She shook her head as I unzipped my jeans, and by then I was so hard it didn’t matter. We were already so deep in the game there was no going back.
“Good, so be a good girl and suck your big brother’s cock. I already told you, your boyfriend will thank me for it. You have to get better at it sometime.”
She didn’t need more convincing before leaning over and tentatively taking me between her lips. Her hand was gentle as she slid it up and down my cock, but the game blurred with reality because I knew the truth, and I needed it as much as the fantasy. Maybe it could work if I said the right words.
“You know, he’s not as nice as me,” I said. “In fact, I think he’ll be a bit more aggressive than this.”
And before she could come up for air, I shoved her down around my cock until I was buried in her throat. She gagged for not even a second before coming up and smiling at me like she had just won a blue ribbon. I pushed her back down and began moving faster and faster as I fucked her, the fantasy full in my mind even as I used her the way she really was.
“Sit up and show me your pussy,” I told her, grabbing her by the hair as she gasped for air. She blushed but lifted her dress, and I stared at her like it was the first time.
“My god, you are so hot, sis. And that little pussy is going to be mine on these days too, you know that right? You know I’m going to fuck you soon?”
Before she could do anything but nod and whimper, I pulled her back down to my cock, rolling us both over until we were on our side.
“But now I’m going to fuck your slutty little mouth until I come.”
“Oh god,” she gasped, letting me fuck her harder and harder.
Blowjobs do not usually make me come. Nothing sweet ever does. But as I shoved her onto her back, my hand on her breasts as I fucked her mouth and throat harder and faster, I knew that I was close. She took all of me, her hands on my ass as she let me use her, and just a few minutes later I growled her name and thrust into her before coming down her throat as she swallowed every drop.
As soon as I was done, I pulled her up for a kiss as he little fingers moved between her legs. I held her by the throat as she brought herself closer and closer.
“You’re going to come for your big brother, and when you boyfriend is fucking your mouth later, you’re going to pretend that it’s me. Isn’t that right, Sis?”
She was coming before I got the sentence out, and I held her closely as she screamed and bit her lip, trembling around her fingers as she called out to the divine.
A few moments later I held her limp body in my arms and kissed her hair.
“Fuck, that was amazing,” she said, kissing me between giggles.
“You are amazing,” I said, holding her tightly as both of us slowly began to return to ourselves.
“How the fuck do you know my head so well?”
“Maybe we just share a brain,” I replied.
She lay there against me for a long time, my shirt untucked, my pants around my knees, and my cock still hard against my stomach. Her dress was askew and one breast was still bared to the world. I pushed my fingers through her hair and kissed her forehead as I whispered thank you over and over again.
Finally, she looked up and kissed my nose.
“Happy birthday, now let’s go eat oysters and get drunk.”
And that’s just what we did.
