I was just organizing clothes in Master's bedroom when I heard Edward's voice.
"Mom, come here! Now!"
I hurried to put everything away and quickly made it to my Son's door. I knocked.
"Enter."
I closed the door behind me and scanned the room for disorder but found none. My girls had done a good job. Edward was sitting in front of His PC with His back turned towards me.
"Get under the desk and give me a good foot rub, will you?"
"Of course, Sir."
When I kneeled in front of Him I looked up.
"Sir, you didn't give us a chance to say thank you after your lesson. If I may say so, I'm very grateful and feel another level of respect for you after that beating. I'm proud to see that you grew up to be as stern as your father" I said and lowered my eyes back to His feet.
"Oh you're welcome, mom. But, just so you know, I don't appreciate women who talk so much" He answered, bending over to smash my lips between His fingers. "I know father lets you babble whenever you want to, but I'll certainly beat it out of my woman when I'm married. I like my women hard working and quiet. It's a sign of a good servant if you can't even tell she's there, don't you think, mother?" He asked letting go of my lips to pat my head.
"Yes, Sir" I answered, but stole a look at His face again and saw that despite His words He was pleased with what I said.
I lowered my head and started to kiss and rub my Son's feet. It went on for a while until His mobile rang. He answered and pushed my head with His foot to the floor resting it on my left cheek. As he talked, He tapped my face lightly. When the conversation was over and He slapped my face a little bit harder as a sign to continue rubbing, I heard Adam yelling from the living room for me to come.
"May I be excused, Sir?" I asked, not lifting from my position without permission.
Edward sighed.
"I guess I have to let you go. But I'm not pleased at all. Come here." He pointed at the floor in front of His chair.
I crawled there and kneeled at attention. He lifted my face with His left hand and kept it firmly in place.
"I know this is not your fault but I'm not happy with you going right now."
He lifted his right hand and started to slap my face back and forth until it was hot and red. All the time He was punishing me I kept my hands folded behind my back, turning my face back to Him after each slap.
"Now, thank me nicely and run along" He said, letting go of my chin. I kissed both of His hands repeatedly before I got on my feet, bent in half in a deep bow and got out of His room.
I entered the living room and saw my Husband sitting in the couch watching something in TV. I stood behind the couch on His left and waited for orders, feeling my cheeks burning. Adam pointed to His feet so I knelt between them. I knew what would happen so I opened my mouth and starred at His crotch. After a few minutes I started to drool.
"All right, sweetie, why don't you get down to it. Do your best."
