Belly Inflation and Expansion Fetishes

Have you heard of belly inflation and expansion fetishes?

Maybe you get excited at the idea of having a bloated belly, or watching someone else transform through inflation.

“The first time I watched someone inflate their belly with a water enema, I was hooked. It gave me tingles in places that I couldn’t explain and frankly I still can’t explain it,” wrote Bloated and Sexy, an inflation fetishist.

What Is Belly Inflation?

Belly inflation or the belly expansion kink is sexual excitement or sexual interest in the inflating of someone else’s or one’s own belly.

Belly inflation can be about the sensation of filling the belly with air or water or the transformation aspect. It can be about having a full tummy, a round belly, or being stretched. It can be about watching someone being filled, or enjoying their full belly.

Belly inflation and belly expansion fetishists often use various methods to fill themselves or their lovers up with air or water to cause an inflated belly. They may do this orally or anally. Belly inflation may itself feel extremely pleasurable, or the effect of the bloated belly is pleasurable, or both.

Belly inflation and expansion can also be very dangerous fetish. People have used all kinds of methods to inflate their bellies, from swallowing balloons to forcing pressurized air up their butts. Whatever floats your boat, but be careful and learn safety and risks before proceeding!

Some people have literally exploded from the intestines, and some have poisoned themselves with water from overdrinking. Use common sense and caution.

Belly Inflation vs Body Inflation Fetish

The belly inflation kink can be related to the body inflation fetish, which is arousal at the idea of someone inflating. Body inflation kinks are more often fantasy and roleplay rather than actual inflation, as the ideas that turn body inflationists on are fantastical, cartoony, and impossible in real life.

There are some overlaps between body and belly inflation fetish, but most body inflationists are not turned on by enemas or belly expansion methods. They are more interested in balloon suits, or illustrations of round blueberry girls floating through the air, or bursting.

How Do People Inflate Their Belly?

Belly inflation and expansion kinks can be played out by filling the belly with air or liquid to distend and enlarge it.

People inflate their bellies by swallowing air, using an air pump, or balloons. They may also swallow a lot of water or liquid. Alternately, they fill themselves with air or liquid anally, using air pumps, hoses, and enemas.

Why Do People Like Belly Inflation?

Most people who get off on belly inflation and expansion can’t tell you why it turns them on. But there are a few different ideas and possibilities at play.

For those who love being inflated, the feeling itself can be very pleasurable. Being slowly filled with air or water and inflating has been described as a slow fuck. Nerve endings all over the body are potentially implicated.

Some like the look of a big belly.

For some, it is the idea of transformation, going from one state to another.

For some, it is specifically having warm liquids pumped slowly into their ass, and then releasing it afterwards. Enemas have a long history of use in sexual pleasure.

For others, it is the humiliation and helplessness. Releasing air or liquid is messy and taboo.

6 More Belly Expansion Kinks

1. Belly Stuffing

Most of us enjoy a good belly stuffing time to time, at Thanksgiving, for example. Even while we feel excruciatingly full, there is a sense of comfort, indulgence, excess, and satisfaction.

We don’t want to feast gluttonously every day, but on those special occasions of a wedding or holiday, it is so good to just give in and eat as much of everything as we like.

Some people combine this thrill with sex. There are many food fetishes. Some belly inflation fetishists enjoy watching someone eat, sometimes a particular kind of food, and get a big belly while they do.

2. Feederism

Not all belly stuffing enthusiasts are feeder fanatics or into fat fetishes.

Sometimes you will see “no BBW” on belly inflation fetish pages, because belly expansion kinks are about getting round and inflated, not about getting fat. So some people are turned on by belly stuffing, but not from the potentially resulting weight gain, or from fat fetishes in general.

However, it makes sense that belly expansion lovers are also often into fat fetishism, because fat fetishes and related feeder kinks cause belly expansion. Not all fat fetishists are into feederism either—lots of people just love big bodies but aren’t interested in feeding of stuffing or belly expansion.

Feederism is sexual excitement from the act of feeding, or seeing a fat person feed, on copious amounts of food. It can be an occasional thrill, or a BDSM lifestyle, where the feedee is fed so much that he or she is helpless and immobile. This is someone who is entirely submissive and dependent for care on their dominant.
