My sister likes taking risks

“I’ll get a condom,” I said, but Emily grabbed my wrist again and shook her head. She pointed for me to lay down on the shag carpet. My penis pointed up proudly, as hard and straight as I’d ever seen it.

Emily stood over me, legs apart. She looked down and smiled. Slowly she lowered herself down. Leaned forward and kissed me on the lips. My penis bounced against her bare, unprotected pussy. God, she looked so beautiful.

“Just like in the movie,” Emily said, “We’re both going to do something risky. We’re going to race toward that precipice. And we’ll see who gives up first. Got it?”

Then she reached back, took my bare cock in hand, and aimed it right at her dripping puss.

Oh fuck. “Emily!” I shouted, “If you put me in without a condom I could…”

“Exactly,” Emily said, “I’m going to stick your dick in my pussy and we’re both just going to sit there. Neither of us moves. We just wait until one of us loses the nerve and pulls out.”

“Fuck. Emily. This… This really is too far now. I mean if I get you pregnant, Emmy? Our whole lives could be ruined.”

“It’s not too far,” Emily said, “Not yet.”

“OK, wait,” I said, “We haven’t done it in a while. My balls are… They feel really full. And my cock. I mean, I doubt I’ll last a minute. Maybe we just have a quick fuck first, get out some of the tension. Then try.”

“No,” Emily said, “That’s the game. There’s the risk. That’s what makes it work. Because there is all that danger. Our whole lives in our hands. Besides, you’ll stop before it’s too late, right?”

I nodded.

“Well so will I.” Emily smiled and picked up my cock again.She placed it at her pussy and then started to slide back. For the first time, my bare head, my naked shaft, rubbed against Emily’s labia. Her vagina. And then I was completely sheathed in my sister. Without anything between us.

“Holy FUCK! That feels fantastic!” Emily said.

“Uh huh.” It was the closest I could come to coherence. I thought we’d been fucking all this time. That I’d known what sex was. It was nothing. Being inside Emily without a condom was like the difference between a scrimmage and a championship final. They were barely the same sport.

“How the hell did I ever let you talk me out of THIS?” Emily asked.

“Pregnant,” I croaked.

“Oh right,” Emily said, “Good point. Anyway, this is the game. Whoever can stay the longest.”

I had to admit, in that moment it was exhilarating. And the same things that made it so exciting — my naked sister, my condomless penis, her unprotected pussy — also made it terrifying.

Emily rocked back onto her knees. She looked down at our juncture and smiled. “I always thought that looked so hot. You buried inside me.”

I could see now that she was teasing me. Using dirty talk to get me to go first. Only she didn’t need to tease — I was ready to burst already. But I held on. I knew I had to. If we stopped now Emily would just make me go all over again. I had to let her have her fantasy, just like she said: get as close to the edge without going over.

I shifted a little and Emily warned me that I wasn’t allowed to thrust. Only to lie back. As if that somehow made things safer. Like her warm, tight pussy wasn’t squeezing, pulsing, pulling at my cock for its precious seed.
