Two blondes, a cuck, and a prisoner

In reality, the drive ended up taking over an hour: traffic was terrible. Just my luck.

When I finally arrived, hustling up the front steps, I could hear some commotion from the fenced-in backyard. A woman laughing--Misty, probably--Along with some splashing from the pool, and a deeper voice. Much deeper… Certainly not Kevin. It must've been the prisoner they were hosting.

I expected to see my brother-in-law when the door opened… But instead I came face-to-face with my niece, Brittany. My topless niece. She wasn't even trying to cover up: she just stood there with a smirk on her face, wearing nothing but a pair of bikini bottoms.

That put me in mind of my wife… But Brittany was quite unlike the MILF beauty waiting for me back home. A little shorter… Skinnier, with a toned tummy… Smaller yet perkier breasts… A pair of long, smooth legs… Painted pink toenails… I couldn't help but look the eighteen-year-old bombshell up and down, before quickly turning my head away as I realized I was ogling my niece.

"I… Hi, uh…" I cleared my throat. "Where's your shirt?"

Brittany shrugged. "Daddy Darnell says this outfit's okay for a day at home with family," she replied, cocking her slim hips to one side. "I guess you're family too, Uncle Darrel! So… What do you think?"

With that she spun on her heel, revealing that her swimsuit was actually a thong. The tiny piece of fabric was nearly swallowed-up by her bubble butt--Jesus, it's huge, why is only THAT part of her so damn curvy?

It was skimpy enough for me to catch a glimpse of what was beneath: a jeweled butt plug, all the way up Brittany's ass, its glimmering end indenting and pushing aside her flimsy thong.

I couldn't speak. I could hardly breathe. I just stood there like an idiot as Brittany opened the door to let me in.

"I'm gonna head back outside with Mom and Daddy Darnell," she said matter-of-factly, prancing off into the house. "Dad's in the kitchen."

Even after she turned the corner, the image of that perfect ass swallowing up that scandalous thong was burned into my retinas… And that butt plug, fuck…

Shaking it off, I stumbled towards the kitchen. The hell is going on here? "Daddy Darnell?"

When I saw my brother-in-law, I did a double-take: he looked about ten years older, twenty pounds lighter, and was totally unable to make eye contact with me.

Kevin was standing at the kitchen counter, putting the finishing touches on a huge platter of sandwiches.

"Ah, hey… Thought I heard someone at the door," he mumbled, barely looking up from his work as he added a few cans of beer to the tray.

"Kevin… Wh-what the fuck?" I was pretty lost for words myself. "What's going on? Why is Brittany--She s-said something about 'Daddy' and she w-was wearing--"

"It's… She…" He let out a deep sigh. "Don't, uh… Don't blame Misty. She just wanted to make Darnell comfortable… Give him a real second chance…"

"What does that have to do with--"

He kept droning on, still looking away: "...I came home one day, and the girls were walking around topless… Then I found them all on the couch, and he was… His fly was open, and… Well, now it's… Uh, it's just… Normal."

"What the fuck? You realize how crazy you sound right now?"

"Just… Just go see for yourself, Darrel" he sighed, gesturing towards the patio doors. "I gotta finish this."

Shaking my head in disbelief, I moved slowly to the doors overlooking the backyard. What I saw was straight out of my darkest fantasies--No, that's not quite right. I'd never even imagined such a thing happening to my family. It was horrifying… Disgusting… And erotic, on a whole new level.

Sitting by the pool was a tall, muscular, tattoo-covered, dark-skinned man, his legs spread wide as he reclined on a deck chair… Completely naked.

Kneeling between his toned legs was Misty. My sister was just as naked as the man she was worshiping: drool was dripping down onto her bare chest as she worked her tongue up and down the man's shaft--

--And Jesus Christ, that shaft! He must've been nearly a foot long… Twelve fucking inches of dark, veiny, throbbing meat. It glistened in the late-afternoon light as Misty's skilled tongue polished it from top to bottom.

Occasionally her mouth would dip beneath… Gracing his pendulous, apple-sized testicles with a kiss and a suck before returning to her long, slow licks.

As I watched in true horror, another body blocked my view. Brittany was rushing over to Darnell, still topless--And soon bottomless, too, as she stripped off her thong, winked in my direction, and threw it at the patio door.

I flinched as the garment hit the glass--And bumped me in a place I wasn't expecting. Looking down, I realized that there was a huge bulge in my pants: my erection was literally pressed up against the door, my modest cock straining against its cloth confines.

By the time I looked back up, Brittany was already on her knees… Joining her mother at Darnell's feet… Licking her way up one side of his long, thick shaft, while my sister worshiped the other.

I was already in full-on panic-and-despair-mode--But what happened next made my heart skip a beat. My beautiful, innocent niece climbed up onto Darnell's lap, squatting over his erection. Meanwhile, her mother slid down further, moving her lips to his huge, heavy balls… And grasping the base of his cock, pointing it up at her daughter's pussy--

--No. Her ass. Brittany was pulling out the butt plug, lining up her tight hole with the monstrous member twitching beneath.

Before I even had time to think "that will never fit," she lowered herself down: my sister lining that dark pillar up with my niece's asshole, allowing the one to penetrate the other… Inch by impossible inch… Stretching, squeezing, swallowing Darnell's meat.

After what seemed like an eternity, Brittany's bubble butt settled onto Darnell's muscular hips. He was buried inside of her… Balls-deep in her tight, teenage ass.

Suddenly, I heard a deep sigh from over my shoulder. "At least she won't get pregnant," Kevin mumbled. "Darnell's obsessed with her ass… That was my first clue, really, when he first arrived… Wouldn't stop staring, especially when she wore those little shorts…" He shuddered. "Didn't even try to hide it."

"...I… Um…" I could barely get a word out. My eyes were still locked onto Brittany's backside as she began working her ass up and down Darnell's rod. She was trembling--Hell, I was trembling just watching that obscene display.

"Misty's another story," Kevin continued, his voice oddly flat. He wore the expression of a man who'd been in a constant state of shock, for days on end. "Darnell, he… He likes using all of her. All her holes. Brittany sucks most of it out, but I've seen how much, uh… I… I don't think she gets it all."

"...Are you saying…"

"Yeah… She's probably already pregnant," he mumbled, watching as his wife stroked Brittany's bouncing booty affectionately. "Guess we don't have to worry about that with her mother, at least. I'm sure at least one of the guests prefers your mom's pussy, but she's post-menopause, so--"

My blood ran cold. "Wait. What guests? Who--"

"Oh. Shit." For the first time since I arrived, I saw a glimmer of emotion in Kevin's eyes. "Nobody told you? She got a CUCI letter around the same time as us… And I guess they make placements based on empty rooms or something, because… Uh… She's hosting three of them."
