It felt amazing. Katie's' pussy was completely wrapped around my hard cock, and as I fucked her she groaned and purred some more.
"Oh my God that's so fucking good, that's SO fucking good!" she moaned. "OhmyGod Daddy I'm fucking Adrian and it feels so GOOD!"
"My pleasure" said Dad shyly as he fucked Mom.
"It will be! Come and fuck me as soon as Ade's finished, I want to feel your cock inside me this deep, it feels so AMAZING and I want to do it with you, too! Oh, oh, OH!!" this last as I came, her filthy talk really getting me going.
True to his word, as soon as I hit the bed, de-spunked and exhausted, Dad took his cock out of Mom's pussy, saying "Sorry Hun, I gotta fuck Katie" turned around, and plunged it into his daughters soaking wet cunt, dripping with his son's cum.
"OOH THAT'S SO GOOOOOD DADDY, IT FEELS SO FULL!!" She squealed as he fucked her while me and Mom looked on.
Watching my sister get fucked was hot enough to get me turned on again in record time, and the sexy sight gave me some interesting ideas. I was already lying close enough to her to be able to whisper in her ear: "Can I lick you out while he fucks you Sis?"
She nodded and said "Yes please" and then Mom said "And can I frig you?" to which she also consented, so we both kissed her and Mom stretched a hand out to frig her as I grabbed a pillow and got under Katie and Dad's heaving bodies. I kissed my way down her body, licking and sucking her nipples while Mom frigged her clit, then I finally reached her pussy. Mom moved her hand to make room for me, and I put my pillow under my head and lapped at Katie's' pussy and Dad's cock as he fucked her, enjoying the two opposite sensations; his hardness and her softness, both of them completely soaked with cum and pussy juice.
Mom must have been at a loose end at that moment, because that's when she straddled me. She picked up my cock and stuffed it into her cunt, then sat down on it hard enough that I sat up a little, burying my face ever deeper in my incestuous siblings' heaving, well fucked cunt and my father's rampaging, stiff cock. I licked the shaft of his prick and moved onto her clit, provoking moans of pleasure, and kept lapping at them as Mom fucked me cowgirl-style.
After a while, Dad took his cock out and let me suck it, and I enjoyed the delicious taste of pussy-juice coated cock once more... it also had dollops of my own cum on it, which I lapped up greedily before sucking his cock into my mouth.
It. Was. Heaven. My own cum, Katie's pussy juice, and Dad's precum all blended together to create a beautiful taste, the taste of love... As I sucked his cock, I heard Katie gasping as Mom leaned over and finger-fucked her again in an attempt to keep her on the boil... I must have really given Dad a good time because soon his precum was flowing like water and he was moaning and groaning just as much as Katie... I felt his cock begin to throb and realized he was about to cum.
I didn't want to monopolize Dad, so even though I loved swallowing his cum I was happy for Katie when he slid his cock out of my mouth and back into my sister's pussy... I went back to lapping at the two of them and that's how I got to be there when they both came.
She was groaning and moaning, and his cock throbbed as it released each great pulse of cum, causing Katie's to squeal with delight and clamp her cunt down hard on his cumming cock, making sure she got every single drop of his cum. A deep groan escaped her lips, and then they slowly separated... leaving a huge amount of spunk for me to lap up!
I sucked and licked Dad clean, then drank as much of our cum as I could from my sisters' pussy as Mom continued to fuck me... soon I could take no more and came as well, causing Mom to gasp and shudder herself, the chain of pleasure riding through our family like a nuclear reaction... and so finally, our session came to an end.
"And you went on like that?" my girlfriend and hopefully soon-to-be fiancΓ©e asked, "You all kept having sex together, living in an incestuous polycule?"
"Yeah! It was great!"
"But didn't it stop you meeting other people? Weren't you all too busy with each other to look for anyone else?"
"Not at all... in fact I got to suck my second ever cock, and confirmed my own bisexuality, through my sisters' first boyfriend. But that is another story!"
