***This is the finale of my 13 part series following an evolving incestuous relationship between adult siblings. While each of the previous stories weave summaries of previous plot points into the narrative, and therefore can be read as a standalones, this one will have much less of that. It will assume that the reader knows what brough the characters to this point, and will only explain or call back to smaller points from their pasts. All previous chapters are displayed in order under the series "A Brother and Sister's Journey" on my profile. All characters in sexual situations are over 18.***
I couldn't wait for my sister to get home from work. I had dutifully, and... if I'm being honest: heroically waited to share this video with her, rather than just jerking off to it as soon as I paid the $30 for it.
After seeing it offered in my OnlyFans inbox, I causally sent Kelly a quick message that said
Lanie just posted a new video titled "Eating and Rimming my Uncle's THICC GF" think I should buy it?
She quickly replied
Uhhhhh.... Fuck yes
followed with
God, I'm here for another 3 hours!!!!!!!!
before finishing with
DO NOT watch it without me!
So I just had to sit there looking at the thumbnail of the video, which showed Ceci's plump ass bent over and Reagan's face buried in it. Every second seemed like an eternity until Kelly got home.
We didn't mess about with dinner, I was just waiting in the bedroom wearing only a pair of Ceci's panties. When Kelly burst in the room she took in the view before her, and just snarled at me before pulling her sweater and blouse off and dropping her jeans, careful to pull her own panties back up when they got tugged down with the tight denim.
She was on the bed and throwing her leg over my face in a flash, nearly pulling my hand away from the mouse on the side table. But, I was able to hit play, and a shot from Ceci's point of view appeared on our TV. The camera was pointed down into her hairy crotch, past her big tits as Reagan crawled into view, looking up into the lens.
"Hey guys... this is the girl that's been dating my uncle. She came to visit me and fucking shamelessly flirted with me... soooooo now I'm gonna rock her world, and you guys get to watch!"
Kelly lowered her panty covered pussy onto my face, blocking my view of the screen. She made up for the interruption by rubbing my already hard, panty covered cock. She started to get really into whatever was happening on the video, and I was having some serious FOMO, so I pried my right hand free of obstruction and swatted her ass as hard as I possibly could.
"Fuck! Ow... you little fucking brat!" She hissed angrily, while still apparently getting the message.
She took up a spot next to me and now I could see Reagan lapping lustily at Ceci's very wet cunt. I popped my dick out of the side of Ceci's panties and started to lightly stroke it. Kelly's hand dove below the waistband of her's, and we both sat, silently watching her daughter eat out our live-in unicorn girlfriend.
"It's been a while since we just jerked off together... you wanna just keep going?" She asked.
"Totally. Like the good old days!" I said, reaching for my vape.
We smoke weed a lot of the times we fuck, but we have both gotten to the point where is has become almost compulsory for solo play... or during mutual masturbation. I hit it deeply and passed it to Kelly, who took her own long drag before leaning over and exhaling out her nose and into my mouth.
On screen Reagan was now plunging two fingers deep into Ceci's pussy while sucking on her clit. Kelly and I exchanged self satisfied smirks a few times as we expertly worked our hands below. Ceci squealed as she had an orgasm that caused her belly and tits to pleasingly shake on screen.
The shot changed to Ceci hiding her face with her hands as she maneuvered onto her knees. She bent over, offering her round ass up to Reagan. Ceci reached back and spread her ass open as Reagan knelt behind her. Ceci moaned deeply as Reagan's tongue slobbered all over her asshole. For a moment Reagan swung to the side so both of their big asses were visible.
"Fuck that's hot" I mumbled, more to myself than to Kelly.
"How long is this vid? I'm already close!"
I hovered the mouse over the progress bar showing that we had another eleven minutes to go. Seeing that, Kelly just said "that'll work" and we kept on playing with ourselves while staring at the screen.
After Reagan got Ceci off for a second time by licking her ass and pounding two fingers into her pussy, the shot changed again. Now Ceci had the camera again and she followed Reagan's movements as she crossed the room and returned with lube.
"Damn Lanie, How is your ass as fat as mine, but you're so tiny everywhere else?" Ceci asked, with seemingly no self loathing, just appreciation for Reagan's delightful thickness.
Reagan didn't respond, she just hopped on the bed and squirted lube into both their crotches to prepare for some tribbing. Reagan was comparatively smaller than Ceci just about everywhere else, but in addition to her glorious round ass she also had thick thighs and when they brought their pussies together the squelching sounds they made were heavenly.
As they writhed into one another, Kelly jammed her fingers in my mouth and I got them as sloppy as I could before she reached under her own leg and slipped them inside herself. I was already ready to blow, but we have a little bit of sibling rivalry when we jerkoff together where its kind of understood that whoever lasts longer wins. Even though we both always win in the end.
So, I popped my cock back into the panties and ran my hands along the underside, through the soft fabric. After a few strokes a small slightly darker spot was visible as I leaked precum. Lewd wet sounds coming from Kelly's crotch drew my attention from my stain, and I saw her working both hands inside her panties as she gawked at the video.
"Fuck" I whined as I shook, gripping my cock through the panties as I tuned the tiny spot into an ever widening, gloopy mess.
"Gimmie" Kelly commanded, and I reached in and slathered my hand in my own hot come, before reaching over and offering it up to her.
As she licked my fingers clean, she never tore her eyes away from the image of her daughter and Ceci with their legs intertwined. With about a minute left on the video Kelly's face became locked in what would usually look like a horrid expression as she silently came.
When the video finally ended, Kelly rolled over and kissed me deeply, tasting strongly of my come.
"Fuck that was fun!" I said
"Totally. Don't tell Ceci you wore her panties though, ok?"
"Why, do you think it would bother her?"
"Well yeah. You know she's sensitive about her weight and it might bum her out a bit that a guy could wear her panties so easily."
I hadn't considered that, and I got a bit lost in thinking about how far Ceci had come in the five or so months she had been living with us. Although I was so happy she felt confident enough to film this sex tape with Reagan (albeit while careful to hide her face from the camera) I was still aware that her body image issues would take longer to address.
Kelly and I grabbed a quick shower together and then went out for dinner, neither of us feeling much like cooking. We spent the whole time at the restaurant immersed in the kind of easy conversation that comes naturally to tight knit couples as well as family, and we were both.
On the way home we got a text from Ceci saying that she was going to be coming home the next day. As we readied for bed we chatted about how things might change now that Ceci and Reagan had hooked up. When I climbed into bed and turned off the light, I could sense Kelly grappling with something.
"To avoid living out an episode of
Three's Company
everyday of our lives, I kind of want to have Ceci tell Reagan that we know about her OnlyFans... and... maybe... hint at what you and I are doing" Kelly finally said, just as my eyes began to adjust to the dark. "But, I want her to make it clear to Rae that we DO NOT want to bring her in, even if she's interested. Because she can't say for one million percent sure that it wouldn't bother her later, or mess he up in some way and... I'm already going further out on a limb than I want to letting her know about it, and I don't want to lose her...."
