Are Secrets still secret if everyone knows?

Tori had me struggling to keep a normal expression. I watched across the table as Lauri looked at me strange, "You okay, bro? You look like you are about to poop your pants."

I tried to answer but I felt my vision blur and an orgasm rip through me. I watched in horror as Tori pulled away quickly and pumped my cock with both hands for all it was worth. My answer to my innocent sister was rolling my eyes back and jets of cum shooting from the other side of the table and falling between us on our food, dishes and table. I could cum so much now our Mom just cheered as the fountain rained all over our breakfast table. Recovering from such a powerful orgasm I looked guiltily into the eyes of my cute sister. She was curious and horrified, "Uh...is that what I think it is?"

"Dessert!" Erika joked. "Better get some before us girls get to it Lauri."

Lauri turned to her Mother in shock, "What? Mom! That's his cum!"

Erika raised an eyebrow before rolling her eyes, "You didn't have a problem when you were licking it up in the sauce last night. Or pigging it up with the icing this morning."

I watched the brunette blush, her eyes widening. "That was? OH MY GOD! WHAT IS WRONG WITH YOU TWO?" She protested but I watched her chest bounce with heavy breaths, licking her lips while staring at the mess. There was a twisted conflict in her, a hunger. "But I don't understand. It was so good. How could cum taste like that?"

Erika wiped some on her finger and waved it in front of her daughter, "Try some and find out. You've already had your fair share. Why not take one little taste straight?"

Lauri blushed before her will broke and she wrapped her mouth around her mother's fingers and moaned, "Sooo good!" She sucked like a slut. It was the hottest thing I had seen in awhile. I felt Tori clean my dick with her mouth and moan herself at the taste. The finger popped out of the cute girls mouth and Lauri groaned, "What is wrong with me? I...need more. It's too good!" Her eyes faintly glowed before she dove face first into the table, my cum pressed onto her cheeks and forehead while she rubbed her face, licking with wild abandon. The cute girl moaned and licked the table, "More! More!"

Meanwhile under the table Tori was passionately kissing my cock, getting as much cum into her mouth as well, "Fuck. So fucking good. Love your cock...."

Erika smiled mischievously at me and licked up some cum she put on her finger again, "I think our girls are finally starting to break! Girls you both seem a bit preoccupied and conflicted. I'm calling in to school for you. You can stay home with Daddy and me."

Lauri turned her head towards her mother, eyes wide, "Daddy?"

Erika winked, "Well that's what you'll be calling him. I'm his little slut and I'm your Mother so that would now make him your Dad. Or Daddy. Whichever you prefer. But either way you either need to get used to calling him that and helping me keep him happy, or get used to seeing your Mommy get fucked by Daddy. Because he's got a hungry appetite!"

"Gross." Lauri groaned looking at the cum all around her face before instincts took over again and she looked at me while licking my cream off the table. The arousal and pleasure in her eyes were clear. The curvier teen felt something inside of her take over and she squeezed her arms together, pressing her tits out for me, "Thank you for dessert...Daddy." The girl widened her eyes realizing what she had just done and scrambled off the table, running up the stairs to her room.

I looked down at the blonde teen babe, "You enjoy watching last night?"

Tori looked away, her face reddening, "Uh...I...well. I learned a lot. It was extremely educational."

I smiled and pulled away from her, walking towards Erika, "Want to see more?"

Tori hesitated. She still saw me as her brother, even if she had been sucking me off. It was a means to an end. Seeing me fuck her Mom was still wrong in her eyes. But I could see temptation and twisted logic prevailing. Tori nodded, "Yeah. It was hard to make out some angles. I'd love to see what Daddy enjoys." Realizing she too had instinctively called me that she blushed and got up, turning away from me for a bit.

I didn't care and just winked at my slut. "Alright. Well, this is going to get loud."
