You run over to your sister's bed. The floor of her bedroom looking like a football field to your shrunken size, its a good thing you're good at running. When you get to the foot of the bed, you grab on to the blue comforter and begin to climb up. With how light you are now, it feels way easier than climbing rope in PE, then you make the mistake of looking back and seeing the long drop to the ground. *gulp* Your fear of heights helps motivate you to not fall down and continue the climb to the top of Kim's bed. "Ha, that, ha, was, ha, hard." You huff and puff as you rest on the covers until you catch your breath. Looking over, you see on your right is your sister's giant face on her pillow and to your left is her glasses and alarm clock on the nightstand. Before you can make your choice, your ears start ringing as the alarm goes off and the floor is pulled from under you as Kim gets up and tosses the covers off of her, burying you in the soft fabric.
The sixteen year old girl gets up, stretching her arms in the air before putting on her glasses and turning off the alarm. As she sits up, rubbing the sleep out of her eyes, Kim hears Hannah opening her door. "Morning honey."
*Yawn* "Hi Mom."
"Do you know where your brother is? He isn't in his room."
"Nope. I think he might have gone over Steven's. He said they were gonna do stuff the other day."
"Then it looks like its just us girls today." Hannah says as she leaves the room. You heard the conversation and tried to yell for help. Now they're not gonna bother looking for you, also your mom sounded too happy for you to be out of the house. Maybe you can see how they act when you're gone. You toss and turn to get out of the blanked cocoon you are trapped in, seeing a ray of light that leads to the outside and crawl your way out of it. Getting out, you breath in the fresh air. Your giantess sister changing into her clothes for the day. She is wearing a navy blue long sleeve sweater, her hair tied up in a pony tail, and she is wearing a short black skirt. That's weird, you have never seen your sister wear skirts or short dresses or anything. Then Kim turns around, walking towards you to get her phone on the bed and you see something dangling between her legs past the skirt. They were two round balls, in a flesh colored pouch just swinging back and forth. Your brain didn't process it at first but then you realize that your sister Kim has really low hanging balls.
"What the fuck?" You stare confused as Kim grabs her phone and starts looking through it as you stare at her low hanging fruit that stretches past her thighs. Each testicle is bigger than you, like tennis balls with the right one slouching lower than the left. Her nut sack is smooth, free of any wrinkles or hairs, almost looking as feminine as her legs. Her scrotum hung thinly off of her crotch then expands outward around her cum factories, giving it an hourglass shape to the whole thing. You notice she is starting to move so you run and jump at her, not wanting to lose the closest person who could help you. You reach out your hands and grab her black skirt, hanging on it as she turns around and leaving her room. You can't believe Kim has a dick, or one so big, or why she is going around the house commando but now you know what she does when you aren't home. You also start to feel something solid behind the skirt, it was squishy but also gave a lot of push back. As you look down to see her family jewels directly behind her and being between her legs you knew it was Kim's monster dong. You feel like you're gonna be sick. Then your giantess sister reached the stairs, you pray she goes slow but this morning has not been your day. Kim rushes down the stairs, her legs kicking left and right which causes you to be flung in all directions. You lost your grip as her enormous gonads slam into you. You grab onto the warm skin to avoid falling to your death, closing your eyes as you bounce up, down, left, right over and over until she gets to the bottom of the stairs. You feel like you're gonna have motion sickness like you were on one of those carnival rides where you're in a sphere as it swings into the air. You take in a sigh of relief that your on the ground floor but the breath you take smells like a mix of ball sweat and after shave.
"Kimmy, why are you dressed up?" You look over and see your mom on the couch, still in her pajamas which are white with pink hearts sprinkled through out the design.
"I just wanted to show off my new skirt." Kim does a twirl which brings up the rim of her skirt. This harmless action for her almost flings you into the air as her balls rise up. The spinning around in a circle causes the g force around you to pull you to the bottom of her sack as the futa's testicles stretch out from her body, your legs flying over your head as you hold on with all your strength until she stops spinning and you fall back below her inner thighs holding onto her boulder sized balls.
"That's not the only thing you are showing off." Kim giggles as your mother flirts with her. "Why don't you get over here and let Mommy have a taste." You watch as your lovely mother gets on her knees, arms spread and mouth open wide as Kim strokes her half chub into a full one. Looking up you see her schlong expanding to a full foot long, her pale shaft bursting with veins. Your eyes look forward as she moves towards Hanna, you see your mom's titanic tits coming at you as Kim's balls slap into her cleavage as she gets a blowjob. You get smothered by your mom's boob flesh and your sister's nut sack as the sounds of knob slobbing goes throughout the room, if they do this every time you leave the house than no wonder Hannah was so excited. You are pulled away from the warm canyon on the milf's chest as she pulls away to admire her daughter's cum producers. "I've never seen balls so smooth. Maybe you can help me out today." She says as her fingers caress the stretchy patch of loose skin. Also of course your mom has a cock, at this point you wouldn't be shocked if Alice had one too.
"Do you want some tea mom?" Hannah smiles then gets on her back facing up. Kim stands over her face with each foot next to Hannah's head, your mom opens her mouth wide and you started climbing up as the futa teen squats down. *SMACK* The balls land on your parent's face as you race to the bottom of the shaft. Looking back you see the huge testicles being swallowed by the milf's maw like a snack swallowing eggs, one after the other. You hear the deafening moaning as Hannah's eyes are closed and she starts sucking in like a vacuum cleaner, enjoying sucking on her daughter's swollen nuts. As she does this an unmistakable tent is protruding from her pants of which Kim instantly sees. "I think someone wants some attention." Kim gets up, *POP* her balls popping out of Hannah's mouth like she was Mr Bucket, This causes them to fling into the air causing you to loose your grip and slide back down to square one as you reach the bottom of Kim's sack. Before you can pull yourself up, Kim gets on her knees and her spit covered coin purse falls on top of you. Pinning you to the hard wood floor as you look up as your older sister pulls down your mommy's pants and panties playfully with her teeth. From your perspective you can only see your mom's huge dick bounce out like a yard stick and smacks Kim's glasses off of her face. The monster dong makes Kim's look petite as the 18 inches stretches out from a forest of black pubic hair surrounding your mom's plump, soft ball sized testicles. "Jeez Mom, you weren't kidding. You do need help Mandscaping down there." The sixteen year old says as she caresses the hairy orbs that are too big for her palms to handle.
"Well then, do you wanna have fun now or get to work." Hannah says with one hand on Kim's hair and the other stroking the magnum schlong pointing at her face.
