Son Dominates Me

My son became very confident and would tell me what to do when i was in the house , or like when i came home from shopping one time he said as soon as i was in the door to get my clothes off and i said " give me chance to shut the front door first" he said " why shut the door i love seeing your big tits and hairy cunt i am sure others would to" , i shut the door and said that's really naughty of you ", being naked in the house all the time for my son meant i was always highly turned on which is why i think he got away with a lot telling me what to do , so that afternoon as always i was naked but i was aloud to put a robe on if someone came to the door, we was in the kitchen and i got my robe and put it on , " what are you doing " my son asked , i said " i am going to hang the washing on the line in the garden" he walked up to me and pulled the tie undone on my robe and then pulled the tie out of the loops, " now you can go and hang your washing out now " he said smiling , i cant go out in the garden like this i told you that no one else can know what we are doing " and what he said next made my legs almost give way with that smile he said " well no one will know what we are doing , but i want people to see your big tits and your cunt" hearing him say that made me give out a moan, " and i think you want that as well dont you Mum " he said, i could not speak i was so excited , he again said you want that dont you Mum you want people to see your big tits and your hairy cunt" , i could only just nod not being able to speak still, " then you better pick up your washing and go out in the garden with your robe open
