Of Helium... - Part 1

"MPHH MHPHPH?!?!?"

The annoyance and questioning surprise in Sylvia's face right back at you, was growing more intense by the minute, as by now her cheeks had expanded full of air to the size of softballs, like two ballooning blobs of puffed up consistency, protruding further from her face as the thick hose - shoved deep and tightly in her mouth between them - was forcing endless amounts of pressurized air from the helium tank beside her, into them and down Sylvia's throat, as the gas was quite aggressive in finding al the right spots to bloat up in her already chubby - soon to be quite the ballooned up one - body...

This inflation experiment she had agreed to, was not what Sylvia expected, especially out in the open on a sandy beach and at that time of the day, and since both of you were usually only just playing around with large balloons and air-tanks, while your obsession with this body inflation thing led you to this crazy thought of trying it out on Sylvia herself to be the balloon this time, and without thinking further into it or asking her permission for it, you just shoved the hose from the tank into her mouth and cranked the tank's valve all the way.

The pressure was intense, and even cause Sylvia tried to play along, she was still in distress more and more as the pressure was building up from inside of her and the results on her body were drastic and immediate as her concern grew even more intense, by taking looks downwards to her ballooning body, past the gargantuan expanding cheeks that were blocking her view even more as the hissing intensified as well, making some nearby people on the beach to start and stare at the inflating spectacle as well...

Sylvia's turquoise bikini top, was growing tighter around her upper body, as the strain on it was growing unbearable, with her boobs already blown up to the size of blimps, almost like a basketball each, and her arms puffy and flailing at her sides, while her bottom parts - the most impressive by now - had blown up immensely, with thighs expanded with air to the size of tree trunks stretching her bikini bottom impossibly, her belly like she had swallowed an exercise ball, and overall a backside that resembled some parade balloon's backside, rather than some actual girl's one...

Sylvia's body was resembling a blow up doll that had been inflated far too much by now, and kept expanding and inflating as you were determined to keep that inflation experiment going no matter what the cost, since you were a stubborn horny guy as well, and you were even enjoying this spectacle far to much as to turn off the tank so early...

"MPHMPHH MHPHPHPH MHPHPHPH!!!!!"

Sylvia kept muffling though the thick hose in her mouth, the distress more intense as she got bigger and bigger, still trying to play cool though, trying to hide all her distress while the hissing and clothes ripping sound intensified in the area around her and people were gathering up even more closely to the both of you. Her bikini fell to the sand in shreds as her body was becoming more spherical by now, almost at the size of a large room and she floated softly above the sand, as her boobs were inflated almost to the size of weather balloons and her cheeks had expanded with helium to the size of volleyballs, the thick hose still siphoning endless amounts of pressurized gas within her rubbery body. People were gathering around more and more, snapping pics on their cells, even recording the scene on video, as Sylvia's size was almost as huge as a house by now, and she floated even higher on the sunny beach, casting heavy shadow for more than a hundred people to cool down under...
