Inflatable Sex (Patreon)

Roger had stumbled across Cassandra’s inflation fetish several months ago when she had left open a story on her computer screen. Roger was your pretty average guy short dark hair, brown eyes, just a little over six foot, in shape, decent looking. He had no idea how he had managed to get a woman like Cass to fall in love with him.

She was a stunning, curvaceous, redhead, she was 5’6” tall, had huge basketball-sized breasts, a narrow waist, wide hips, and a plump ass. Her legs were long and her thighs thicc as the kids would say. She had emerald green eyes, her hair was long and curly. Roger had honestly been shocked when he found out his goddess of a girlfriend actually wanted to be even bigger than she was now.

In more ways than one, most of what Cass had favorited on her profile were stories about women or men being blown up into huge balloons. Roger wasn’t sure how he felt about it at first, but as he read more stories he quickly found himself getting aroused by the idea of doing the same thing to Cassandra.

He had told her to strip down and wait for him in the living room, he had something special planned for her. He made sure it was the living room since it was the biggest room in the house and he wanted lots of space. He had hidden several air tanks around the house for this day just in case. Again the biggest one was in the living room.

He stroked her cheek and kissed her plump lips “okay babe close your eyes, no opening them until I tell you.”

Cass giggled “okay,” her sultry voice said as she squirmed on the couch.

Roger took the lubed up end of the hose and slipped it into Cass’s pussy. She cooed as she felt the thick tube slide in. Roger couldn’t help, but grin slyly she had no idea what was about to happen and he was already rock hard with excitement. Of course, Cass was excited too her large fat nipples were already hard. Cass’s nipples were easily bigger than Roger's thumbs.

“Okay here goes,” he said as he spun the air tank valve all the way open. A powerful blast of air pushed its way into Cass’s pussy. She let out a gasp of pleasure as her belly started to rapidly inflate bigger and bigger in front of her.

With her eyes still closed her hand came to her belly rubbing it all over “ohhhhh Roger what are you doing to me?” Cass moaned as her belly expanded out bigger and bigger and bigger against her hands. It went from full-term pregnant to looking like she had swallowed a yoga ball in seconds. Soon more of her joined in on the swelling. Her pussy started to inflate puffier and more sensitive.

Roger rubber her expanded mons with his hand, Cass squealed in pleasure. He leaned up whispering in her ear “I’m pumping you up like the naughty balloon you are,” Cass shuddered as he said that letting out a lustful groan “open your eyes.”

Cass’s eyes snapped open and she smiled delighted “ohhh my god look at me! I’m blowing up! Ohhh I’m already so big! Bigger! Roger, I want to be bigger!” Cass’s breasts had now joined in on the fun. The once basketball-sized tits were now getting close to the size of bean bag chairs. Her nipples had inflated much larger as well now the size of protein powder jars.

“Ahhhh I’m turning into such a pervy blimp! Pump me up more! Inflate me bigger! I want to be your horny balloon!” Cass cried out as she started to inflate all over. Her hips expanded wider her waist swelled out as more and more air rushed in. She quickly lost her hourglass shape as her entire body filled with air. Her arms grew tighter and tighter as they plumped out with air.

Cass was already bigger than the couch she had been sitting on. She swelled and swelled and swelled taking up more and more space in the living room expanding out in all directions. “Ohhh yes I’m just a horny ball now! Fuck me, Roger! Fuck me while I blow up for you!”

Roger looked at Cass’s inflated pussy he knew his current cock wouldn’t be much good for that. Taking out another air tank he hooked the hose into the end of his cock. Turning the valve open he bellowed in pleasure as his large cock inflated even bigger. “Ohhh shit!” he shuddered as his cock and balls inflated rapidly bigger and bigger. It wasn’t long before his cock and balls were taller and wider than he was.

With the hose still in his cock pumping him up and up and up. He pushed his now-massive cock into his round lust-filled girlfriend. Cass screamed in pleasure as his behemoth of a cock stretched her pumped up pussy. As he thrust into her Cass’s massive balloon body bounced off of him up and down.

Her gigantic breasts and nipples were the only things left on her that weren’t a part of the massive ball she had become. As they fucked Cass’s ballooning body pushed all of the furniture to the edges of the room. She grew bigger and tighter with each passing moment. Still, she begged for more “ahhh yes! Roger yes! More! Pump me bigger! I want to be the biggest horniest blimp ever! I don’t want to stop!”

As she cried out begging for more Roger couldn’t hold back any longer he came harder than any man had cum before. As he shot his load into Cass it was a mix of cum and air. All of the air he had pumped into his balls was now being stuffed into his blimp lover. The two of them cried out in pleasure as they both came harder and harder.

Cass’s body was filling the entire room now. Not an inch of the room wasn’t covered by Cass’s massive balloon body or her mountainous blimp tits. As the two of them rested in post-orgasmic bliss Cass let out a throaty chuckle “I think we’re going to need to get a bigger place.”

The End.
