Cleaning my step-mom's feet

I go inside, find a box of tissues, and return to clean my step-mom's feet. She has picked up a magazine, so sits there reading it while I clean her feet, and acts like she does not notice that I am there.

I make sure to do it carefully and thoroughly, then go inside to dispose of the used tissues, then I go back outside.

As I walk through the patio door, I hear my step-mom say:

"You dirty little boy, go take a shower so that your cock is clean."

I do as she says, and head to my room for a shower and then return, wearing a clean swim suit. Millie looks up at me over the magazine and says:

"Did I give you permission to get dressed."

"No step-mom." I reply.

Millie does not say anything, but just looks at me over the magazine. I understand what she wants pretty quickly, so I take my swimsuit off, revealing my semi-erect cook.

Millie looks at my cock briefly, then says:

"You dirty boy, has the sight of your naked step-mom already made you hard?"

I nod, and say:

"Yes, I mean, yes step-mom."

Millie looks down in her magazine again, and without looking at me says:

"I have no use for you at the moment. Sit down in your sun lounger and wait for my command."

"Yes step-mom." I reply and lean back on the sun lounger next to hers.
