Blood.

I honestly don't remember if it was his teeth or his nails (my memory-forming skills are disturbingly poor during good sex; there have been times when having multiple orgasms has caused me to basically black out a few minutes), but Alan made a two-inch cut on my left breast. He held my face and kissed me and with a little sigh laid his cheek against mine, and then while he was fucking me he made me bleed.

I feel so proud of the mark. I keep pulling my neckline down a little and looking at it and smiling.

I love it when sex comes with souvenirs.
