Similar to https://civarchive.com/models/217624/sitting-on-a-balloon-sdxl-mini-v018 but trained with a larger dataset and targeting Stable Diffusion 1.5 instead of SDXL. This dataset in particular includes balloon popping content, so non-poppers tread with caution.

Intended primarily for base SD1.5, but I've had unexpectedly good results with FurryToonMix and Yiffymix.

Some useful tags:

NonPop (For images with no hint of popping balloons. Not reliable, but it seemed like a good idea to have.)

For Controlling the Balloon Style:

Realistic Balloon (Skews towards photography)

Unrealistic Balloon (Unintuitively, this skews towards balloons that are physically impossible. Primarily intended for the Negative Prompt.)

Detailed Balloon (Attempt to invoke more details on balloon necks and ties)

Simplified Balloon (More Cartoony)

Bubble Balloon (For balloons that are effectively indistringuishable from a bubble in that they tend to be perfectly round and have no opening.)

Balloon Clip (Attempts to add a clip instead of a tied knot)

Tied Balloon

Necked Balloon

Overinflated Balloon

Soft Balloon (When the balloon has low resistance against the force pressing on it.)

Squishy Balloon (Attempts to show more stretching and distending on the balloon surface.)

Underinflated Balloon (There were few of these in the dataset, probably won't work well.)

One Balloon (Will reduce the balloon count, but won't always get it down to one.)

Two Balloons (Probably won't work well, there are few samples for this.)

Many Balloons

Popped Balloons

Balloon Pieces (synonym)

Imminent Balloon Popping (It looks like a balloon will pop soon, intentional or not)

Trying to Pop a Balloon (When a character looks like they're trying to pop a balloon.)

Pop Tease (When a character looks like they're going to pop a balloon, but there is no evidence that they have popped any yet.)

For Controlling Viewing Angles:

From Above

From Below

From Front

From Side

From Back

For Controlling Pose:

(Honestly, I highly recommend using ControlNet instead to do custom poses if you want something specific.)

Bouncing (Which should involve more visibly energetic riding)

Grinding (Might be more suggestive.)

Rubbing (Similar, but a bit less abrasive)

Humping (Blatantly suggestive)

Crotch (Often visible with sitting and bounces poses, might be useful)

Spread Legs (Same Idea)

Implied Masturbation (When the hints are mostly in body language.)

Masturbation (When the hints are more explicit than body language.)

Trying to pop a Balloon

Sitting on a Balloon

Sitting

Balloon Fetish

Looner

Content Rating:

(I rarely use these, I have no idea if they were actually learned.)

Safe

Tame (Synonym)

Questionable (For when it's unclear if the imagery is sexualized.)

Suggestive (For when it's clear the image is hinting at sexualization, but not explicit.)
