“You weren’t complaining while it was your dick.” She countered, staring me right in the face as she spoke. I stared in her green eyes and then my gauze dropped to her sexy lips, lips that had been wrapped around my cock not ten minutes ago.
“I think you liked having your own sister suck you off, didn’t you?’ She was right in my face now, and mad as a hornet.
“Yea… I did…” I began to calm down, and realize I’ve always wanted to stick my dick down her throat — and more.
“You’re the sick fuck here, not me.” Becky yelled as she turned and stormed off down the street. As we passed my car, I grabbed her and pushed her inside.
“Where are we going?” She asked, giving up the fight.
“Home.” I answered, slamming the door and running around to the other side.
“Are you going to tell mom?” Becky asked, suddenly sounding worried.
“I should, but I think we can work this out between the two of us instead.” I told her as I started the engine. I think she knew that I meant business and didn’t fight me as I pulled her head down in my lap. I took the long way home and each time I got close to cumming, I’d pull out and tell her not until we got to our driveway. I wanted her to know that our folks were going to be right inside as she sucked off her brother.
Twenty minutes later, I pulled up to our garage and turned off the engine, the sounds of her slurping getting louder now that my car was off.
“We’re home.” I announced, running my hands through her long brown hair. She started to get up, thinking we were finished, but I pressed her head back down.
“No, I’m going to cum in your mouth right here. I bet mom is looking out the window, wondering why I don’t come inside. I wonder if they suspect that their daughter is sucking their son’s cock?” Becky didn’t say a word, but just started sucking again.
“How many cocks did you suck tonight?” I asked as I pulled out of her mouth.
“You fucker.” She answered, her voice raspy from sucking so many cocks this evening.
“Well, that’s better than being a cocksucker, isn’t it?” I laughed, making her pay for being such a slut.
“I hope you enjoy this, because it’s the last time.” Becky told me as I reached down to slip my hand up her top.
“Like hell it is, you’re my new play toy, when I want a blowjob, you’ll open your mouth, understand me?” I threatened. She didn’t answer as I wedged my dick back between her soft lips. I could see the curtain in the living room draw back as our mother looked outside. I wondered if she noticed Becky’s head bobbing up and down in my lap.
“And that rule about not cumming in your mouth?” I asked her, not expecting a response.
She knew I was going to flood her tonsils and kept sucking as I played with her tits. I especially liked pinching them as she squirmed. Eighteen years of putting up with her shit and finally I was getting my revenge. Two seconds later, I couldn’t hold off any longer and shot a wad of sticky goo in my sister’s mouth. I moved my free hand down her stomach and into her panties as I blasted away. Just as I thought, her slit was wet as hell…
