"Oh, my god .. Will!?!"
Looking up, you see the giant, smiling face of your older sister Kim. An excitement shines in her eyes, standing up a little straighter as she peers over the edge of the opening house.
"He's so tiny!"
You take a step back, shuddering under the giantess' gaze. As you do, your back presses up against something soft and yielding. A light moan sounds out and the wall pushes back, swelling and growing larger after you press your tiny body against the sensitive glans of Alice's growing penis.
"He still feels good, though! Such a good, little wife!"
"Wife, huh?" Kim smiled, looking down as the whole dollhouse began to shake anew. "Well, its time for your wife to have a visit from the pool boy!"
The front door opened wide, the light from the outside window quickly dimming as Kim stepped in front of it. She was tall enough that she didn't have to kneel or bend down as the house sat on the table. First, Will saw the blue of her jeans, then he saw the open fly with the heavy bulge of her cock pushing outward through the thin cotton of her straining panties. Nimble fingers with a light shade of pink gleaming on the nails moved up to the waistband and slowly began to peel them down.
Fear gripped him, his breathing erratic. Alice's monstrous penis was bad enough, her huge erection now standing at full attention to his side. It filled up much of the kitchen and dining room, the tip so full and broad that the mushroom cap grazed the ceiling as it reached more than halfway down to the ground. The stiff pole, it's 7" length more than twice as long as Will, looked over 12' long to his shrunken eyes. And Kim promised to be much, much larger. A fact that was reinforced as her flaccid length slowly appeared with the slow reveal of his giggling sister.
"Hello? I've come to clean the pool!"
It was thick, even soft it was thicker than Alice. Wrinkled and dark in color, Will's nose was quickly filled with her strong scent. It was masculine, powerful, but also undeniably feminine, and it caused his head to swirl. Blinking through the haze, he watched as foot after foot of big, meaty, girl cock bulged outward. As the waistband of her tortured panties finally crested the bulbous tip, the whole of it bounced free, swinging with a heavy weight that belied its impressive size. The full sack of her fat testicles bunched upwards, the skin smooth and hairless, as she tucked her panties beneath their bulk. The flaccid shaft nestled between them, rolling back and forth slightly as it cradled itself before Kim's hand came up to grip the giant length. Even her long fingers couldn't encircle its girth, only grabbing about half of it before lifting it up where Will watched the tip get pushed forward.
It mashed up against the door frame, too large and too big to fit. The impact caused the house to shake. Will jostled to one side, his foot landing in a slick puddle of Alice's pre-cum, and he slipped. Crumpling to the floor, the shadow of Alice's girl cock fell on him and he looked up in time to see the tip burble forth another fresh dribble of warm pre-cum just before his little sister grunted and leaned forward. The stiff bulk of it crashed on top of him, pushing the air from his lungs, and he cried out with a loud squeak that fell on deaf ears.
"Oh! God, that feels good!" Alice's young body shuddered, rubbing her fat tip over her shrunken brother and feeling his writhing, helpless body beneath her bulk. She forced her eyes open to look at her bigger sister and smiled while nibbling her lower lip cutely. "Where is the pool boy? My wifey is cute enough for the both of us!"
"Mmm," Kim banged against the wall again, her soft cock futilely mashing up against the door and its frame again. "Its been a long time since I've played with this dollhouse. I think ... I think I've grown a bit since last time!"
Will's sister giggled together and he raised his hands to try and push the heavy rod of Alice's stiff penis off of him, but the cum slicked surface of her cock head made it difficult for his fingers to find purchase and his efforts only brought jolts of pleasure as they danced over the sensitive flesh of her cock. He finally managed to roll to one side, only to mire himself in the warm puddle of precum that had freshly pooled on the ground. Flipping onto his back, feeling too heavy to climb to his feet, he watched helplessly as Kim finally managed to get a firm grip on her swelling girlhood and aimed it directly at a front door obviously too small to accommodate it.
"I'm gonna MAKE it fit!"
The dollhouse lurched backwards as Kim began to force her huge penis inside. The tip of it pushed its way forward, the rim of her glans pressing up against the open door frame. The contact caused her to groan loudly and Will watched it swell with the sensitive pressure. The skin went taut, shiny and turn a deep purple in color. It seemed angry, strong, and the door frame creaked as the slit opened wide as the tip was slowly spread apart. Behind it, the shaft curved upwards, Kim jerking her hips and forcing her length into the dollhouse. Wood groaned, plastic cracked, and then something gave way as all of her flaccid meat suddenly rushed into the interior, flooding the living room with hot and gently throbbing flesh.
"YES! Ahh ... there we go." Kim's glazing eyes peered down, looking through the opened house and her smile went from ear to ear. "Don't you have a kiss for the pool boy?"
Even soft, it was bigger than Alice's and Kim's huge cock was slowly and steadily growing bigger. Will could see her heart beating through the thick veins that were starting to stand out across the length. Behind the bulbous head, the shaft was starting to thicken, pushing against the doorframe that was already squeezing it
"Yeah, wifey," Alice giggled as her nose wrinkled cutely, "make your husband happy as I watch you be nice with our guest."
