Casey looked at me and then at the ass I wiggled back and forth in front of her “I get a turn too,” I said feeling my pussy press against the underwear that was still pulled to the side. “It’s your final experiment, fuck me.”
Her eyes went wide but not with surprise, with hunger. She dropped to her knees, crawled over, and stuck her face between my thighs.
The hot breath and rough little tongue buried in my cooze, pushed me over the edge and I attacked Linda with new vigor. Sucking her back into my mouth and moaning as another wave of pleasure rattled through my brain, I felt Casey’s impatience.
Her face vanished, and I felt her hands on my ass.
I thought of the size of her and wondered what it would feel like. I had taken a cucumber almost as big, but I had never seen a dick as big. I bobbed my head on Linda’s meat and tried to focus on relaxing the muscles of my pussy.
Casey’s cock pressed against me and I arched my back. It was so big I arched my back a little and spread my legs wider.
Casey’s dug her fingers into my waist as she pressed forward, pushing a little more of her heft into me.
Linda looked at me and then at her daughter behind me.
I opened my mouth wider and sucked more of her cock into my mouth as I pressed back against Casey. Pain and pleasure mixed somewhere inside of me. I loved it. My body seemed to glow as another orgasm sent starburst behind my eyes.
I looked up as Linda began moaning in earnest. Her cock was already beginning to pulse, the head flaring at the back of my throat. Do it. Cum in my mouth. I want you to fill me up while your daughter fills my pussy.
Casey was fucking me faster and faster and my body was bouncing onto her mother’s lap now, her cock hitting the back of my throat while Casey impaled me from behind. I knew it was about to happen. All three of us were going to cum together. Excitement tingled across me.
And then something moved. I saw it out of the corner of my eye and when I glanced over, I almost froze. There, peaking through a gap in the door, was Casey’s little sister, Stephanie, her mouth wide open, her eyes as big as dinner plates.
I didn’t know what to do. It was too late to do anything. Linda put a hand on the back of my head and pushed her cock deeper into my throat. I couldn’t breathe let alone see the door.
“Oh, yes, baby.” Linda pumped my mouth until cum began gushing down my throat.
I arched my back and Casey fucked me harder, taking long strokes and pushing herself deep inside of me.
Swallowing Linda’s load and pushing her oldest daughter toward another orgasm, I looked back over at the door which was still partially open, but empty. Steph had disappeared, probably just as her mother was filling my mouth with her bliss.
“I’m going to cum,” Casey whimpered as her heft throbbed inside me, stretching me even wider and going deeper and deeper every time she pressed into me.
“Do it,” I licked cum off her mother’s thigh. “Fill my pussy,” I met her next thrust and then the next, grinding my hips back until her cock was so deep inside me I gasped for air. “Fuck yes, Casey. Give me that…”
“Oh, oh, oh…” Her cock exploded inside me. Hot jets of pleasure vibrated through me.
I ground back against her as she filled my insides. There was so much cum. I could feel it filling me up and then squeezing past our bond and running down my thighs.
