“It doesn’t change anything,” Becky said. “I mean it, Jack. We did what we did, and don’t get me wrong, I really fucking enjoyed it, but that’s all that’s ever going happen.”
It was about ten minutes after the text from our parents revealed that we would be spending the night alone in the cabin. It was also about ten minutes since I had watched her finger herself to orgasm just a few feet away from me. I remembered watching a little bit of my cum land on her thigh, and thought about how it would still be there, drying on my sister’s skin.
My cock was soft in my boxers, but that image sent a little pulse of desire through it.
“I know,” I replied. “Just looking. No touching. You said already.”
“Fuck!” she shouted, dropping her head into her hands. “We shouldn’t have done anything! You’re my little brother, for Christ’s sake. What the fuck were we thinking?”
I know what I was thinking; I wonder how wet her panties are right at this second. Are they sticking to her? Is she aware of her wetness? How would she smell if I got down on my knees right there and then and pressed my nose against them? Would she stop me if I did?
