One way is to make it a story about self - discovery. The girls initially might be ashamed of their butt plug tails, but as the TF occurs, they come to realize that these tails are what make them special and unique. They then use their new - found confidence and transformed selves to make a difference in their world.
They can focus on their unique body shape. Embrace the fact that their big butt is part of what makes them special. Just like in real life, confidence comes from within. They should remind themselves that their body is beautiful as it is.
One common theme could be the exploration of transformation itself. It might show how the girls adapt to their new forms in the horse anthro world. Another theme could be the relationship between the transformed girls and the regular horse anthros in the story. Maybe they face acceptance or rejection issues.
In TF stories, big butt girls might rock high - waisted jeans. High - waisted jeans can accentuate the curves and make the butt look more shapely. Another style could be A - line skirts which flow gracefully over the curves.
One success story could be for those with certain medical conditions like pelvic floor issues. Some people have reported that using a butt plug, under proper medical guidance, has helped in gradually strengthening the pelvic floor muscles. This in turn can lead to better bladder control and overall pelvic health.
I don't think they are that common. Sexual experiences like using a butt plug are very personal and often not something people casually talk about. There are taboos and privacy concerns associated with it. Also, different people have different levels of acceptance towards such sexual exploration, so not many would openly share their 'first butt plug sex stories' if any at all.
One interesting plot twist might be that the transformation was not accidental but part of a grand plan by an evil force. And the girls have to figure out how to reverse it while dealing with the new challenges of being horse anthros. They may also discover that some of the horse anthros they thought were friends are actually working for the evil force. Another plot twist could be that the girls' transformation is a key to unlocking a hidden world within the horse anthro realm that no one knew existed.
Well, the first time using a butt plug can be a very strange experience. You might feel a bit of discomfort at first. But if you take it slow and use plenty of lube, it can become more comfortable. It's important to relax your muscles too.
If it's your first time with a butt plug, here are some tips. Don't rush. Take your time to explore your own body and how it responds. Read up on proper hygiene as well. After you insert it, don't move it around too much right away. Let your body get used to it. And if there's any pain that doesn't go away, stop immediately.
