(This is a custom clip and I can make one for you too! Just me a DM!!) My thought is Erin (the daughter) comes home after being fucked by her dad and actually catches her dad and Emma in the act. She overhears how Daddy blackmailed Emma and is getting her to stop tormenting Erin. She's surprised when Emma starts seducing her dad and even sticks around when they start fucking, but leaves a little after they start. It would cut to a few days later and Erin is conflicted. She's happy that Daddy got Emma to back off, upset that he's fucking her bully/cheating on Mom and conflicted about how he fucked her. She didn't want it, but after it happened and after watching Emma act as "Daddies Girl" she's finding herself kinda jealous. Finally, she decides to confront Daddy. Erin walks into Daddys room, dressed up (I'm still thinking about what outfit but I am a big fan of garter belts with stockings. Maybe even the same outfit from the third video, after all "You liked it last time Daddy"). Erin starts off still kind of conflicted. "I heard what you did for me Daddy, you got Erin to lay off me. But you're fucking her? What the hell?!" Feel free to improve a bit. Stuff like "I can't believe you. Did you get her to blackmail me into fucking you? How could you? Did you want me that bad? You really like filthy collage girls, don't you Daddy" Those are just some suggestions, pepper them through the video, don't feel like you need to stick to a script. This all leads to Erin making up her mind and getting in her knees to get Daddy hard. She's hesitant but excited. She wants to thank Daddy for getting Emma to back off, and the taboo of being with her dad again is exciting. After sucking on him for a bit she timidly asks Daddy to fuck her face, to make her Daddys good girl. After sucking on Daddy for a while she pulls back and smiles and says something like "OK Daddy. I know you love anal; I could tell from the last time we were together, and from watching you with Emma. You can have my ass again Daddy, it's ok, I know it's what you really want." Feel free to change the lines a bit, whatever you think works in the scene. This time Erin beds over to let Daddy fuck her ass from behind. It hurts at first, Daddys big, but she asks him to keep going. After enjoying it for a while and encouraging him she looks back at Daddy and says something like "I know what you really like Daddy. You like it when your girls are dirty for you. I'll be your dirty girl. Come on Daddy, take that cock out of my ass and stick it in my mouth. Let me taste my ass." After cleaning Daddys cock for a few minutes she asks if Daddy wants her to ride him again. She rides Daddy, taking the cock back into her ass and coos, enjoying the feeling. She rides him for a while longer before smirking and doing ass to mouth again without being prompted, she just pulls out and immediately goes down on him. After she cleans his cock she smiles "See Daddy? I can be your dirty girl too" The she lays down and asks Daddy to keep fucking her ass. This keeps going until eventually she can sense Daddy is going to cum, and she begs for him to come in her ass. Feel free to improve dirty talk through the video, like I said, starting hesitant and kinda timid but getting more and more into it as the video goes. After Daddy finally creams her ass she sighs, enjoying the feeling, and after Daddy pulls out, she slides down off the bed to clean Daddys cock one more time, moaning and finally enjoying the taste of her ass off of Daddys cock. At the very end of the video, she smiles up at him and says "You know Daddy, I think I could enjoy being your fuck doll too... You know. If you want."
