Say When

I was returning to my home state after visiting my long distance girlfriend. The bus, despite the lengthy journey, was mostly empty except for the two women who had decided to sit next to me. One was a blonde with enormous breasts and plump lips. The girl between the blonde and me was very plain looking, completely flat chested with long dark hair.

With nothing else to do we all eventually started to talk to one another. I don’t know how but the subject of my girlfriend came up.

“Did you have fun with her while you visited?” Asked the blonde.

“I did, until the end.”

“Oh no, you didn’t break up did you?” Asked the dark haired girl.

“In a matter of speaking…” I said, blushing.

The two girls noticed my blushing and looked quizzically at me.

“Let’s just say that when she said she was close to bursting she didn’t mean she was pregnant. It was quite literal.”

A look of relief came into their eyes and they laughed.

“Ah, so that’s why you’re heading home. You accidentally popped her!” Said the blonde.

“I wouldn’t say… accidentally.” I said with a sheepish grin.

“How’d she burst?” Asked the dark haired girl with a lot more enthusiasm than I expected.

“By overinflation. She just never said ‘when!’”

The two girls smiled and the topic changed for a bit. But I noticed the dark haired girl (her name was Amanda) frequently look down at her flat chest.

“Something bothering you, dear?” Asked the blonde.

“Oh no, no… I just… I wonder what it must feel like to have such… ample… mounds.” She gestured sadly to her chest.

Suddenly the blonde and I had a wicked idea. We glanced at each other and I instinctively knew we had the same one. Without a word exchanged between us we reached down and pulled Amanda’s shirt up.

“Hey! What’re you two do-oooooooooohhhhh!” Her protest was cut off as the two of us wrapped our lips around her nipples (she wasn’t wearing a bra) and began to blow into them like the nozzles on a beach ball.

Immediately her non-existent breasts turned into small round orbs that jutted off her chest as we blew into her. She gripped the arms of her chair and squirmed as we blew deep and long into her body, her new assets plumping up into watermelon sized breasts in minutes.

We stopped and let Amanda adjust to her new breasts. She looked down in amazement at what just happened and fondled herself involuntarily, biting her lip and making cute little moans of pleasure as her balloony breasts squeaked.

“M-more.”

It wasn’t a question, it was a demand! The blonde and I went to work. We blew and blew into her breasts until they reached the size of weather balloons. If the bus driver looked up it would be quite a bizarre sight to see. Two enormous flesh colored balloons breasts sandwiched between two people rapidly inflating them.

Amanda continued to squirm. She let her fingers slip between her legs and was furiously pleasuring herself as we inflated her. I heard creaks and groans coming from her inflation, but she never told us to stop! So we continued to inflate her bigger and bigger…

KABOOM!

Without warning we got blasted in the face with a gust of hot hair as the scraps of poor Amanda fluttered into the seat between us. Her empty pants and shoes littered at the base. We had just popped Amanda like an over inflated balloon!

The blond laughed heartily at this. She played with the scraps before brushing them off the seat. Then she moved to sit down next to me in Amanda’s former seat.

“She’s not the only one who gets big, is she?” Said the blonde seductively. She was pointing towards my pants and I looked down to realize I was having a raging boner.

I tried to cover myself with my shirt, but the blonde just pushed me back into my seat and unbuttoned my pants. My underwear was a tent and when she pulled them down my freed member stuck up straight into their air.

I sat with bated breath as I watched her bend over and wrap those gorgeous plump lips around my tip. I groaned as she began to give me the best blow job I had ever had. Just like poor Amanda I gripped the armrests and squirmed in my seat, occasionally feeling those plump breasts bobbing up and down on my leg.

Then suddenly I felt a new sensation. The blonde had taken a deep breath through her nose and without taking her lips off me began to blow. I felt a cool rush of air flowing inside me and my belly began to poke out of my shirt. A second blow and my arms and legs started to feel stiff as I couldn’t bend them. A third and my whole body began to swell up. A fourth, a fifth, a sixth… how long was she going to keep blowing me up? Unless…

Panic began to cut through the intense pleasure and I wiggled my arms helplessly. If the bus driver could look back they’d have seen one enormous flesh colored balloon inflating out of nowhere. But that panic quickly subsided as the blonde kept inflating me. Puff after puff I began to round out. My body creaked and I let out multiple moans through my plumped cheeks. My arms and legs had almost completely disappeared and my head was squished between the rubbery skin of my body as I turned into a completely round balloon.

The only thing sticking off of me now was my hardened manhood in the mouth of that gorgeous blonde. And still she wasn’t stopping!

This is what it must’ve felt like when my girlfriend was being inflated by me! The pleasure was unbearable. I couldn’t think straight! If I had enough awareness of my plight I might’ve been able to call out “when! When!!!”

But I didn't.

So the blonde kept blowing. And I kept getting tighter and tighter. I felt myself reach a breaking point and I felt myself cumming into her mouth as I orgasmed. But that didn’t deter her in the slightest, and after swallowing she continued to blow and I…

KABOOM!
