"Daddy i have something to tell you...but you can't get mad! Okay so you know that credit card you gave me that was just for emergencies? I kindaaaa...maxed it out." You immediately start to get mad, but she stops you by reminding you of something that happened last week "Remember when you & Mommy stayed at that hotel and you called to say goodnight? Well Daddy..you accidentally didn't hang up the phone." To your horror she tells you she heard you & your wife fucking. And heard you call your wife by her (your bbgirl's) name, and ask her to call her Daddy. She says that it was SO messed up but maybe you two can make a deal? She'll have sex with you and you don't get upset about the credit card bill! She strips and sucks your cock & balls so cute & shyly, and then agrees to let you put it in her ass. When you start fucking her though the mood quickly changes "OWW ow omg, Daddy!! Maybe this wasn't a good idea, pull out!!" You don't though, and you roughly pound and fuck her tight little hole until you pump her full of cum! LOTS of taboo dirty talk!
