Popping Revenge

Cynthia watched in horror and rage and confusion as the mysterious females’ head bobbed up and down on her boyfriends’ cock. She had just returned from her modeling shoot in Florida and the only thought she had was to be with her boyfriend. The red hair suddenly flung back, the females’ honey colored ass forming a delicious bubble as her back arched and she hoisted up her big, fat tits and wrapped them around Luke’s thick shaft. Cynthia’s green eyes widened when she saw the face of the mystery slut; the face of her best friend Lucy, smile lustfully at Luke while she squeezed her round jugs tightly over her boyfriends’ nine inch monster. Cynthia couldn’t believe her eye’s, she was completely awestruck; standing there watching her best friend titty fuck her boyfriend. Luke thrust his hips rapidly into the tight cleavage of Lucy’s bountiful bosom, his face scrunched up in pained ecstasy as he desperately tries to hold off his impending climax. Lucy’s pouty lips curl up in a smile, her sky blue eyes sparkling with lust as she wrapped her mouth over the swollen, pulsing head of his sex and sucked hard. That was all it took as Luke groaned and tensed, thick wads of cum jetting into Lucy’s awaiting mouth and the busty little slut swallowed it all. Cynthia felt sick, watching her friend jerk off Luke, pumping his juices into her hungry mouth until his cock fell limp in her grasp. Lucy licked her lips happily and stood, readjusting her tight pink mini-skirt; sliding it back over her round rump and then stuffing her very ample bosom back into its confines. Luke eased up his shorts over his limp member, his eyes satisfied and a content smile on his face.

“Are you sure Cynthia is cool with us fooling around Lucy. I mean... I know you guys are cool but...”, and he let it trail from there.

Lucy smile coyly, leaning in close, close enough that her lips brushed his.

“I told you, she told me to take care of you while she was gone...,”purring like a cat, “So I did. It’s like our little game.”

With that she kissed him while Cynthia quietly eased out of the apartment and closed the door. It took only a few minutes before she heard Lucy leave and then holding back her rage and her tears she walked into her apartment. Luke was setting up dinner because he had been expecting her in an hour but she, to her horror, got home early.

“Hey baby,” he said with a great smile, “you just missed Lucy. I have to tell you; she took great care of me, thanks.”

Cynthia smiled and hugged Luke; it was odd because she wasn’t mad at him, he had been honest but her eyes were cold as she thought of the proper revenge for Lucy. That night Cynthia made love to Luke and to both their surprise she became pregnant; with twins.

Six Months Later...

Cynthia eased her purplish blue dress over her much bigger breasts, widened hips and very round belly. She had cut her blond hair short, just above her shoulders at her agencies request for now she was modeling Maternity clothes. Her waist was full and tight already; having swelled out a good two and a half feet before her, a sensuous gravid orb of creamy flesh. In six months she had packed on about twenty pounds; most of it was just her belly, the rest was in her milk filled double D’s or in her much rounder ass. Luke had been ecstatic about the whole thing and totally focused on her and the babies. As did Lucy, offering to help them as Cynthia got bigger and heavier with child but Cynthia had not forgotten the last “favor” Lucy did and it had taken her six months to devise the proper payback.

It was early in the afternoon when Lucy arrived at Cynthia’s apartment, wearing a long flowing dress that caressed her voluptuous curves nicely. Lucy had called her over for a last night out on the town before Cynthia’s tummy got too big for her to move. The door was open as usual and Lucy walked in.

“Cynthia, you ready babe?”

From the back room came the sultry voice.

“Can’t you read?”

A glass of champagne sat on the tha table with a note with read:

Start without me...
I’ll be ready in a second.
Cynthia

Lucy smiled and without hesitation gulped down the liquid. Its effects were immediate as the world around her blurred and spun. In the haze of consciousness Lucy could see the rounded form of Cynthia, she could feel her helping her to sit, her voice garbled and strange and then darkness.

Her head ached as she awoke. Dizzy and somewhat nauseas Lucy blinked to force her eyes into focus and when she looked up she saw Cynthia and Luke looking at her. She tried to move but immediately noticed her that her legs were cuffed to the chair at her ankles and her hands were bound behind her back.

“Looks like she’s awake,” Luke said casually.

“Good... I do hope our balloon is ready,” and there was coldness in Cynthias’ voice that made Lucy shiver and squirm. A look of confusion came over Lucy then as she felt the chilly rubber tube stuffed in her noticeably sore pussy. Glancing down she noticed that she was totally naked except her silver bra and now she was pissed.

“Hey, what the fuck is going on?”

Luke smiled.

“Well, six months ago you betrayed your best friend... now she’s returning the favor.”

With that he leaned in and kissed Cynthia and then left the room. Lucy knew exactly what he was talking about and she blushed and shivered. Cynthia waddled slightly with her new size and moved passed Lucy until the red head no longer could see her but she could hear her move and the distinct sound of a valve twist and the hiss of gas registered quickly for she could feel the cold air gush into her sex. It felt weird, tickled almost as gas pumped into her womb and she could feel her belly beginning to bloat slightly. Cynthia gently stroked Lucys’ expanding sides which sent an awkwardly pleasurable sensation through her body. Slowly her belly grew, becoming rounder and more distended and the pressure increased with each passing second; the young woman soon looked pregnant in her fifth month.

“Cy...Cynthia,” Lucy panted as her poor tummy stretched audibly and she felt herself becoming increasingly full, for now she looked several months pregnant and ready to drop, “Cynthia...unngghhh...I know I...ooohhh...screwed up b...but this is a bit...mmmnngggh...extreme?”

“Shhhh... balloons don’t talk,” and with that there was another twist of a valve and the gas pressure came much more forcefully. Lucy winced as the pressure in her very big, very tight belly increased. It was becoming very painful within her and she desperately wanted to stroke and sooth her ever expanding belly. Her eyes widened in pain as Cynthia reached over her and pinched a dangerous amount of her gravid orb, distended out as if she were full term with triplets.

“Are we starting to get a little full yet, mmm?” she whispered as she teased the ever rounding ball of flesh which stretched and squeaked in protest, “Oh my, we certainly are. Well, my plump little balloon... just a few more minutes and we can play a different game. This new one is loud, sudden, and requires a lot of clean-up after it’s over. Got a guess as to what it might be, my dear?”

Now Lucy whimpered for her belly was a massive turgid sphere of honey colored flesh, her sides bloated and taunt as the gravid orb distended well over her knees, her belly button stretched to oblivion as the perfect sphere grew like a monstrous bubble before her wide and fearful eyes. Lucy could feel her belly quivering and aching; wanting nothing more than to bust, and the thought; now looking over to Cynthia and watching her run a long, thin, razor sharp needle over the vastness of her explosive orb, did not seem to far from reality.

“Mmmmm,” she moaned in protest, too fearful to speak or moan in case it caused her to pop.

The pressure was incredible and her whole belly felt ultra sensitive as knew she had reached her limits for no more gas was filling her and her belly simply throbbed with fullness. Suddenly the she heard the hiss stop, just as she felt herself on the verge of popping. Cynthia stepped out in front of her, holding the needle and a piece of string.

“Well, you’ve made a good balloon and I think you’ve gotten what you deserve.”

Cynthia turned and opened the door; looking back at the hugely swollen female, “But Luke says he owes you too,” and Cynthia yanked the string. There was another twist of a valve as the door shut behind Cynthia and Lucy whimpered the pressure in her belly increasing beyond imagination as cold water gushed into her plump, ready to burst body. Lucy clenched her teeth and grimaced as the liquid and gas mixed and churned within her; taking her beyond her body’s capacity, the pressure too much, her belly too tight...

Cynthia stroked Luke’s cock with determination and timed it just right; cum splattered on her own swollen belly as a thunderous, wet POP filled the air.
