Inflating Sisters

Terry smiles as he sees Tanya and her sister waiting near the door as he leaves work. The sky is dim and he looks down at the two five foot tall sisters. Their faces smile back at him and Tanya wraps a arm around him to give him a hug. Her long black ponytail dances across the top of his arm as he hugs her back and she says, “I have a surprise for you.”

Terry leans away to look at her, “Really? What is it?”

Tanya holds a finger to his lips, “Shhh you’ll see.”

Terry nods and looks at her sister June. “Okay. Hello, June.” June smiles and nods back a hello because she is unable to speak. The two lead the way to the car and the always polite and silent sister trails closely behind.

A short car ride later, Terry is sitting on the couch of his living room with Tanya in his lap, leaning on his shoulder. He smiles as she gently runs a finger around his ear and June cooks a meal in the kitchen. Terry pretends to be focused on the science fiction movie on the television, but if asked he couldn’t tell you what it is about. Tanya whispers in his ear, “I got the stuff to make me big.”

Terry’s eyes widen as he looks at her, “Where did you get it?”

Tanya smiles slightly, “A new store in the mall called Inflated Concepts.” Terry starts to move to get up and she stops him. “Whoa….whoa..slow down. Be patient.”

Terry looks at her confused, “It’s your fantasy to get big. Why wait?”

Tanya gently squeezes his shoulder, “I want to be as big as I can be, but I don’t want to pop. So we’ll blow my sister up and measure so I can get big safely.”

Terry arches an eyebrow, “And your sister is okay with this?”

“What’s she going to say?”

Terry shakes his head, “That’s just evil.”

Tanya giggles softly and slides over to the other side of the couch where both her drink and her sister’s drink are sitting on a table. She pulls a vial out of her bra and pours some of the contents into both drinks. Tanya slides back into Terry’s lap and tucks the vial back into her bra. “We’ll drink it while we eat and after dinner we can get big.”

Terry smirks, “You have this all planned out, don’t you?”

Tanya smiles and shifts her eyes playfully toward the ceiling, “Yep!”

Dinner is quickly consumed and the three quietly watch television. Tanya nervously shakes her feet and occasionally glances at June wondering if the transformation has begun. She begins to feel warm and her face feels like it’s on fire. Moans begin to escape her mouth as she grips Terry’s shoulder and feels her skin changing. She struggles to glance at June and sees she is breathing hard and gripping the side of the couch. Tanya smiles on the inside and her moans grow louder. Terry just stares at Tanya in disbelief.

Slowly Tanya catches her breath and slides off of Terry’s lap. She smiles as she sees June still silently struggling to catch her breath. Grabbing a hose in between the couch and wall, Tanya moves toward June and slides her sister’s stretch pants down. She forces the end of the hose into June’s butt and flips a switch as June’s eyes go wide. A hissing sounds as pressure builds in June and her mouth silently forms curses. Tanya smiles as a loud squeak sounds as June’s belly begins to stretch outward and her sister reaches to remove the hose from her butt. Tanya frowns, “Terry, stop her!”

Shrieks of rubber sound as Terry grabs June’s wrists and holds them at bay as she swells with air pressure. “How big are we going to make her?”

Tanya smiles, “As big as she can get.”

June stares at her sister in shock and the feels the pressure mounting inside her, stretching her outward. Her sides squeak outward, her back curves outward, and her arms and legs bloat with air. She mouths silent words, pleading them to stop, but neither make a move to stop her inflation. Her mouth hangs open as the sensations grow as she inflates bigger and her sex sweats juices. She looks down at the swelling sphere torso as it approaches her shoulders and legs. Her mind screams at her that this is impossible and can’t be happening, but something else deep inside her wants more. Her eyes squeeze closed as her belly button pushes out to be flatted on the curve of her growing sphere torso. She breathes heavily as she continues to inflate and asks herself why her sister and her boyfriend wound do this to her.

Tanya watches as her sister helplessly inflates and a loud squeak sounds as she gently prods the surface of her inflating sphere body. She laughs as June gaps from the stimulation, “Oh that feels good? I’m going to love being inflated.”

June attempts to glare at her sister, but fails as too many pleasurable sensations wave through her mind. The pressure inside, the tightness of her body, and sensation of stretching bigger and bigger. Her arms and legs squeak as they are swallowed to their elbows and knees into her swelling sphere body. Loud groans of rubber fill the air as her sides swell against the arms of the couch and she takes up the whole couch. Terry gently pushes her onto the floor before she can get wedged and she lands with a squeak. June gasps from the sensation of hitting the floor and droll drips from her open mouth as she grows tighter and tighter. The hissing sounds hollow sounding as her sphere body groans and meets her hands and feet. She feels her neck bloat and is slowly shrining into her expanding sphere body. She gasps heavily as she grows bigger and tighter. Her sex rains on the carpet it’s rubbing and stretching against. A squeak sounds as she jerks her head and is rocked by an orgasm. She closes her eyes tight as she feels ready to pop and rides the waves of orgasmic pleasure. Four thumps sound as her hands and feet are absorbed into her ballooning sphere body. The curve of her body gently brushes against her chin and Tanya shuts off the pump.

Terry strides around her, “She’s big.”

Tanya smiles, “Let’s see how big. Measure her.” Terry grabs the bundle of measuring tape and hands one end to Tanya. She watches as he walks with one end around June and soft creaks sound as he rubs against her tight ballooned body. A rubber groan sounds as Terry meets the end Tanya is holding and pulls it tight. “How big?”

“Eight feet.”

Tanya claps her hands softly as she smiles, “Oh goodie! I can get eight feet big without worrying about popping. She flips on the pump again, the hissing returns, and June begins growing again. She retrieves another hose from behind the couch and walks seductively toward Terry. “Put this in your mouth.”

Terry arches an eyebrow, “Why?”

Tanya smirks, “To make you a little bigger. You drank some of the formula too.”

Terry frowns as he looks at the swelling June, “I don’t want to get as big as her.”

Tanya leans up against his body, “I’m not going to make you that big, but I will make you bigger in a few areas.”

Terry sighs as he takes the hose, “I don’t know how you talk me into this stuff.”

Tanya giggles as air rushes into him and his belly squeaks outward. She unbuttons his pants and drops them to the floor. She looks him in the eye as he swells with pressure and she grips his member. It squeaks as it grows to attention and begins to swell with air. She tugs on it, “Does that feel good?” Terry moans as she tugs and his body resembles a pregnant man’s. She feels something brush her hand and she looks down to see his balls have expanded as well. Tanya gently pokes him in the belly and it squeaks loudly as she pulls the hose from his mouth. She gasps as she inserts it into her own rear and air begins rushing into her. “Oh! Time for me to get big.”

Terry gently rubs his hands across his bloated belly with a few squeaks, “I’m fat.”

Tanya eyes widen as she sees June’s face, “Whoa I don’t want to pop or have my face do that!”

Terry looks to see June’s face as swollen outward. Her eyes bulging out of her head and her cheeks bloated outward. “Oh my.”

Tanya smiles as her belly passes six months pregnant and her hands gently rub her belly as the pressure stretches her bigger. Her skin feels tight and sensitive as her body swells like a balloon on the end of a pump. Her body groans and creaks as it swells bigger. “I’ll be immobile soon, baby. Be ready to measure me!”

Terry watches as Tanya’s sphere body swallows her legs to the knees and her arms to the elbows. “I’m ready.”

Tanya moans with pleasure as her tight sphere body swells bigger and grows tighter. Squeaks sound from her body as it creeps towards her hands and feet. Her neck slowly shrinks into her body and a horrible shriek of rubber fills the air as her inflating body presses into June’s massive expanding body. Tanya feels the couch at her back and her sister pressing in on her front. She frowns, “I would’ve thought you’d popped by now. Terry, I need more space. Pop her.”

Terry asks, “Pop her?”

“POP HER!”

Terry nods, “Okay.” He waddle to a pair of scissors and waddles back to the front of June with them.

“Wait!” Tanya glares down at him, “Don’t do it near me! Go to the other side of her and do it.”

Terry waddles and squeaks to the far side of June as Tanya moans as her dripping sex is stretched across the carpet. He grows excited by her sounds and watches as she moans loudly with the building pressure. He shakes his head and returns to the task at hand. He whispers sorry to the June as the curve of her body inches closer to him. He stabs with the scissors and a shriek of rubber sounds, but June doesn’t pop. “Damn.”

Tanya feels the increasing pressure being pushed upon her by her sister’s sphere body, “POP HER BABY! POP HER NOW!”

Terry stabs fiercely twice, shrieks of rubber fill the air, and defiantly June remains intact. He curses and forcefully stabs with the scissors again, a shriek of rubber sounds, and a loud bang quickly follows. “OH god.”

Confusion fills Tanya as she continues to feel the pressure of June’s swelling body, “Terry? What…what was that pop?”

“My cock…….oh god…my cock popped.” Terry glares at June’s expanding sphere and squeaks of rubber sound as it pushes against his bloated belly. He feels the pressure and the bookshelf behind him. He struggles to move out of the space, but finds he is stuck. He fiercely stabs with the scissors over and over filling the air with horrible shrieks of rubber.

“Terry?!”

“I’m stuck, Tanya!”

“Baby, try to free yourself!! You have to measure me so I don’t pop!!”

Terry continues stabbing as June swells into him, “I’m trying!!” He forces all his might into one stab and it fails just as the other attempts, but the scissors are knocked from his hands. The scissors fly across the room and Terry curses as he feels his inflated body squeezed tighter. His body groans louder as it is squished flatter against the book self, “Tanya, I lost the scissors!”

Anger fills Tanya, “You what?!!! All you had to do is pop her! How do you screw that up?!”

“I’m…..sorry……she’s hard….to pop.”

Tanya swallows, “Okay, baby! Find a way to free yourself so you can measure me! It’s going to be okay!”

Suddenly a loud bang sounds as Terry succumbs to the pressure and pops like a birthday party balloon. His fragments flutter to the floor as the two sisters continue to swell into each other. Tanya feels tears escape her eyes and she clears at the massive blimp of a sister swelling into her. “You bitch! You popped Terry!! I loved him! Why do you have to be so selfish?!” Wordlessly June continues to swell into Tanya as she fails to build enough pressure to push back on her. Their bodies squeak and groan as they both grow tighter. June gasps as an orgasm hits her and Tanya moans loudly as her body grows even tighter. A loud screeching of rubber sounds as June’s inflated head is stretched flat against her massive sphere body and Tanya laughs, “You’re running out of room, bitch! You’ll pop soon!” June feels explosively tight and believes her angry sister’s words are true.

A deafening kaboom fills the room as one of the inflating sister’s bursts and the remains flutter to the ground. A newly freed air hose whips about the carpet and the hissing continues as a strained groaning fills the room. Tighter and tighter the remaining inflating sister, June, approaches her bursting point. Her expansion creeps to the slow crawl and her skin becomes painfully tight. Her thoughts drift through waves of pleasure and pain as she thinks this is the most horrible day of her life. Her sister popped like a balloon, Terry burst like an inflated dog toy, and herself inflating helplessly to her own popping. Tears run down her face and she wishes she could speak, but she doesn’t know if she would scream for help or just curse madly. She sighs mentally as her skin begins to turn transparent and admits it’s likely no one would hear her.

Suddenly a loud boom sounds and the air pump falls silent. The pressure within June levels off and begins to subside as air begins to leak out of her through the hose that filled her. Her skin loses its transparency as she begins to shrink and hope fills her. She smiles through the tears as the pressure fades and she slowly returns to a smaller size. June knows she will live past this horrible day and with a little time be returned to normal or at least she hopes.
