After that satisfying, secret fuck, and Cindy's whispered words, I could not concentrate at all for the rest of the movie.
When it was over, we both got up, Cindy kissed aunt Christine good night, and then gave me a big hug, squeezing my ass, and kissed me good night as well, announcing that she was going to take a shower and then go to sleep.
Aunt Christine went into the kitchen to clean up from dinner and I wandered upstairs a few minutes after Cindy did, and I saw the bathroom door open just a bit.
I peeked in, only to see my niece standing sweetly naked, her beautiful body all there for me to see. Our eyes met through the slightly open door, and she smiled knowingly, presenting herself to my view. She reached her hand to her crotch and slowly wiped between her lips, showing me that my cum was still dripping from her pussy. And then she slowly closed the door to start her shower. That was just a preview.
I changed into my pajamas, and headed back downstairs to help Aunt Christine finish cleaning. We both headed up to bed, but instead of relaxing for sleep, all I could think about was how much I wanted my niece's body.
A few times, I thought aunt Christine was sound asleep and almost got up, but I had to be patient. Just after midnight, I could no longer wait, and I slipped carefully out of the bed, not disturbing her at all.
