working like a slave

After being away for a few days, which included some great hot hotel monkey sex, we had a day at home to work on chores and home repairs.  T asked if I was available to do some things for her and I responded by dropping my pants to show the brass ring around the base of my cock and balls.  She was happy to see that I was in servile mode after having come recently.
She had a list of things to do and after I finished the first couple she had me stand before her and told me to drop my pants.  She used a pen to write SLAVE on my white shaved pubic mound and made two tally marks.  I was to report to her after each task to have another tally mark added.  The SLAVE had to be freshened up after getting smudged after a few hours.
It wasn't much, but it was a reminder of why I was doing these chores and that she was acknowledging them.
I enjoy having her write on my body, leaving her mark of ownership, especially when it is as her slave, even if it is just in fun.
