The morning

The next morning, Katherine was woken by her mother moaning in her ear.

"Mm, Brad, yes baby, fuck your mommy's ass!"

And just a moment later, fingers slipped into her own wet and vibrating pussy. She moaned, but that was cut short as her mother’s lips once again met hers, and they moaned into each other’s mouths. Just then, Katherine opened her eyes to see her brother staring down at her as he fucked their mother’s asshole. What a difference a few days make, Katherine thought. Mmm, but she couldn’t deny how amazing it all felt, like it was oh so natural for this to happen.

Katherine was roused from thought at a movement near the door, and saw her father walk in to the room, totally naked and sporting a hard cock. Katherine’s mind went blank as her pussy vibrated and came around her brother’s fingers.

“You like your mother’s asshole, Brad?” He said as he walked over toward them. Katherine knew in the back of her head this wasn’t right, but it felt soooo good. She didn’t care, she wanted to be a slut!

“Oh yes, dad, you were right, it’s definitely her best hole! Ooh, we should definitely anal spit roast mom!” Brad withdrew his fingers from Katherine as he suggested double-fucking her mother, and she willingly opened her knees wide as her father walked up to her. His hard cock nestled up to her wet pussy and then pushed inside, her slick wet hole welcoming him in.

“Mm, that’s a great idea son! Especially since we gave my baby attention last night with that DP”

“Oh fuck yeah, dad, that was great. Mm, mind if we switch? I want to try out Katherine’s ass again.”

Katherine came around her father’s cock as they talked about using her like a piece of meat. God this felt good! Oh but, he stopped? Oh, no, there was a cock… oh yes, mm, her brother’s big cock in her ass! If this was wrong, she didn’t want to be right!

“Mm, gotta say though, son, I do still love your mother’s pussy. Mm, darling, do you want my cum, huh?”

“Oh god yes dear, plaster me!”

Katherine felt the same way, hoping she would catch a few splatters from her daddy’s sweet cum. She didn’t have to wait for long, though, as her brother pulled his cock from her ass and moved around to her face.

“Here you go, slut, you want your brother’s cum? Do you want his cum all over your face?”

“Oh god yes Brad! Please, cum all over my face bro! I want your hot sticky cum all over me!”

She got what she asked for shortly, his salty cum spraying all over her face. From her father’s grunts, she knew he was done too, and she turned over to face her mother’s sticky face.

“I love you, mommy!”

“I love you too, baby!”

They kissed, swapping cum, as Katherine's brother and father looked on, satisfied grins on their faces and cocks starting to get hard again.
