My Daughter

My daughter is 24 she was married but left as he was abusive. Her mother my wife passed away eighteen months ago and my daughter moved in around four months ago when she left him, she is 5 ft 2 ins , slim long hair and nice breasts not too big.
She is very loving and gives hugs to me.
Two weeks ago I had left to go to work but came back to get something from my bedroom she sleeps late as she is not working so I walked quietly not wanting to wake her, as I past her door I heard moaning and thinking she was in trouble open her door, her bed faces the door and as I looked in, her knees were up, her legs wide open and she was slipping a cock shaped dildo up and down her wet pussy, her eyes were closed but she was moaning and saying yes Daddy, fuck me, I was divided and knew I should go but I couldn't take my eyes off her dildo filled pussy.
I had a huge erection she opened her eyes saw my erection and as I said sorry and went to turn away and leave, she said said stay Daddy it's ok you can watch me if you want and started to move the dildo up and down.
Then before I could say anything she said I would love to see your cock Daddy, mom said it was big and fat, it's not that big it's seven inch erect but as fat as my daughter's wrist. I dropped my pants started to Jack off while watching her, shortly she orgasmed spurting liquid down her thighs, two more strokes and I blew my load on her leg and bed. I then turned left and went to work.
No mention was made by either of us, but two days later was my birthday, I said we can go out, but she wanted to cook for me, after a nice dinner she said to stay sat on the chair in the kitchen, she was bringing my present, she came back wearing a baby doll see through nightie no bra or panties, walked over unzipped my fly, took out my hardening cock and bent then put the head in her mouth, just until I was rock hard and to get it wet she said to slip in her pussy as she stood straddled me and slipped her wet pussy onto my cock with ease, when fully seated she said happy birthday, we fucked got up went to her bedroom where I had to taste her pussy see if it was as juicy as her mother's. My daughter cannot have children so I can fill her pussy with lots of cum.
She says she only wants my cock, she is not interested in other men.
She told me after mom told her I was a good lover who could do cunnilingus really good then had to explain what that was. She said she loves filling in mom's role in bed while enjoying the benefits.
