My Master, my son

'You're late' my son told me as I entered my house.
'Hush!' I whispered 'my wife could hear you!!'
 'I don't give a fucking damn of that whore!' He said looking me directly in the eyes.
'Sorry....' I said
He punched me in the nose.
'Sorry what?' he asked.
'Sorry master'
'I may be in you asshole son's body, but I'm still you master Tim, and I don't wanna hear any goodamn complains from you. Understood?' he said pressing my son's bare feet on my face.
'Yes master'
In that very moment I saw the front door opening. It was my wife coming home.
'Hi boys, sorry I'm late' she said and then looked at me on the ground. 
'What's happened??' she asked concerned.
'Aw mum! you'r here' my fake son said ' dad fell down just now, I heard the crush from upstairs' and helped me up. 
My master was good imitating my son, and his strong attitude in my son's body made mo so horny.
'Yes Sarah, just an accident' I said smiling ' don't worry'.
We had a normal dinner, my son talked about his school, his girlfriend, it seemed that my master had access to his memories...
'After dinner you are gonna come in your son's room and fuck my dick. Understood?' he whispered when my wife were in the kitchen.
'Y...yes Master' I said with a smile.
