Our house was dark when I got home from my rendezvous in the park with my mother in law, but Sophia's car was parked in the drive. I opened the front door and in the low light from the street lamp I saw my wife's naked pregnant curves as she kneeled before the front door.
She spoke from her knees and I could hear that she'd been crying and was trying not to show it, "I heard you pull in. I wanted to be waiting Daddy. To show you that even when I'm all fat and pregnant and can't fuck you like I should--I'm still your bottom bitch. I'm still completely your property."
I was already reaching down to help her to her feet but she refused to rise.
"Soph', don't be silly, I love you, and you're so beautiful. I love that you're pregnant. Pregnant because of me. It's exciting. I feel like I possess you in a way that I never have before..."
"I know that daddy," she still sounded sad but now with a note of petulance, "but I just got all emotional knowing you were out having your way with my mom. I mean, mostly I was just excited, thinking how you were gonna rock her world and turn her brain inside out like you do to me. But it's a big step and I started to get insecure, you know?"
"Oh baby..." but she cut me off.
"You reek, by the way! I mean, it's hot especially cuz I know whose pussy juice I can smell on you. But oh my god! How many times did you guys fuck?"
"Well I fingered her in the parking lot and then I titty-fucked her right there while she blew me. Then I took her into the woods and you were right that she was hot to buttfuck. And then I reamed her out one more time when we got back to the parking lot. In fact," I smiled, "I didn't have her clean me after that last butt blast so..." I let it hang there but she was on it immediately.
"So you want your wifey to clean her mom's ass juice off your triumphant daddy dick with just her mouth and tongue? Isn't that a little demeaning? Making her debase herself like that? Shouldn't a woman be ashamed if she's drooling to taste her mom's colon off her man's big buttfucking crotch cannon?" By now she had my shorts down and all that followed from her lips for a while was vigorous slurping and sucking. She pulled back to rest her jaw and resumed talking, "god, you didn't even take her pussy did you! She must have been really craving a deep anal dick down." She resumed sucking and I realized I had more to tell her.
"Sophia, she's a buttslut like you are. You see, she confessed that it was her father who took her anal virginity, he had all your aunts that way when they were old enough. But it doesn't sound like he molested them, just let them come of age and seduced them"
She had stopped sucking now and I could hear the anxiety in her voice, "Wait! Does that mean that he's my dad too?!"
"No baby no, she says he only ass fucked his girls, I think that's part of why she was so hungry for me to violate her ass. It's something extra-intimate for her. Plus I think the women in your family are just natural buttsluts from what I've seen. It's like God gave you an extra pussy back there by mistake."
She had paused her oral cleansing of my now very stiff member, "But, did she actually tell you who my dad is?"
I guided her face back to my dick, I knew having her mouth full of dick was soothing and reassuring for her and I also found it arousing to know that from now on she would always associate finally learning the truth of her origins with being in this position of submission and with the humiliating task of her cleansing her owner's womb-wrecker of the taste of her mother's conquered rectum. This was one more moment of embroidery in the tapestry of my complete ownership and dominance over her. She slurped at my now leaky precum and waited.
"You and your sisters are your step father's bastards. Your mom's mom couldn't get pregnant anymore and so when your mom was legal breeding age she let your step grandfather have at her. I think your dad had already gotten her to give up her ass to him and so it seems like she was primed for a paternal figure to take it further and claim her as his fuckslut" she was sucking harder and moaning around my cock, actually fingering herself as I revealed her own family history, "she said he kept her pregnant because he insisted on drinking her breast milk" she was whimpering while she sucked me and I could see her hand wailing at her naked dripping crotch, "and that he used to fuck her and beat her to keep her in line. That she couldn't resist him because of that. Your mom was your step-granddad's bitch starting as soon as she could give legal consent" she came then and had to stop sucking me for a moment to take rasping inhalations of air.
I took the opportunity to close our front door. I then guided her face back to my groin, raising my hard prick to rest on her forehead so she could clean my scrotum's peach sized orbs. She cupped my balls in her pussy sticky fingers and I continued,
