Since I was a kid I always wanted to have a sister but unfortunately, I am an only child, my parents never had other daughters.
That never stops me to ask every year for Christmas to have my own little sister to take care of and play with. With no result every year.
This year I turned 18 years old and I was enslaved by my father. He has started to domesticate me, he has told me that an owned girl should wear a collar to show respect to her father, not wear panties because hiding my holes is disrespectful to my father, and also never cum unless my father says so, in fact, I have not allowed having orgasms since I turn 18. Daddy has turned me into a horny denied girl and I have obeyed him, his precious daughter has not cum not a single time because I am a good girl, and good girls do not cum if their daddy does not want it. I just want to respect my father.
This year I still ask for a little sister. I could not avoid imagining her being 18 years old and help daddy to domesticate her, to make her daddy's slave, like me. And this year, because I have been a good girl who has not cum, daddy has given me what I always wanted, a little sister. And a daughter, it has been a two in one gift.
It all started this 25th in the morning, I was sleeping dreaming about having a little sister when I wake up and suddenly I see my father. He has already undressed me and his big fat cock was inside my cunt. Daddy told me I have been a good girl for not cumming and so he will give me a little sister, but he won't breed with my mother, he will breed with me instead to have a double-daughter for him to enslave in 19 years, daddy will have a daughter with me his own daughter, I will be the one who will carry my own sister in my belly.
This is the best Christmas gift ever!
My father only has one condition, I must remain denied and don't cum. He told me I would be allowed to cum but then I won't be pregnant with my sister. Obviously, I choose to remain on the edge and not cumming. If the price to have my own sister-daughter is to renounce orgasms then so be it, I will do it, good girls don't cum. I am a good girl.
Once daddy finished inside me he told me to look at it, I could see how daddy's seed overflow my cunt, the proof that I will become pregnant by my own father, my little sister. I can't wait for her to become 18 years old, as her mother and big sister I will teach her to edge and not cum like me, so she can join me as our father's slaves as mother and daughter, big sister and little sister. Who knows, maybe daddy will be able to breed with her too.
