This is the ultimate way to serve your Man - you don't keep it to yourself how well he's trained you but you are a living proof of how good of a Master he is to his friends as well
I love when I am serving my DADDY and there is a knock at the door and it is friends of his he invites them in and there I am in my thong panties and my hands cuffed behind my back and he says to them “this is my bitchboi slave use him as you wish” it so degrading and it really turns me on uuuummmm
