Dragon Ball

Hmmm, interesting... got any examples of what they look like?

About all the information you need about the Dragon Balls has been given, but I feel it's worth mentioning Capsule Corporation, her father's company. As the name suggests they make all kinds of devices (up to the size of houses, cars and planes!) which compact down to handheld capsules for easy transport. When she appears it's usually with some extremely handy capsule tech, most of which she has developed herself. I feel capsules offer more sexy potential than the Dragon Balls.

When all are collected together in the anal cavity of a person, they glow a bright gold and summon forth a mighty dragon cock!!

Sometimes they glow a bit sometimes. There's big ones (namekian) and smaller hand sized ones (earth).

I don't quite remember the series in which Bulma dressed like this (I only watched the later series). However I do recall a plot line where she had a dragon ball and Goku had to do something to get it from her? Anyway what you could do is amp up this idea and have her ball sack stuffed with dragon balls, making it look large and heavy. Then she can squeeze or cum them out :)

They're basically wish-granting devices

The balls are orange with Red stars on them! The first one got one star the second got two stars and so on until you collect all 7 of them! When you got all seven you can call the great dragon Shen Long and he will fullfill one wish! The dragonballs will disappear in all directions after you made a wish and the dragon is gone! After that you have to find them again to make another wish! There are dragonballs from earth that git the size of a fist and there are the bigger dragonballs from planet Namek that got the size of a humans head! If you got more questions feel free to ask!

They're seven translucent golden spheres with stars inside. Each ball has a different number of stars, from one to seven.

You gather them all and use them to call the great dragon and make wishes. When they're used they glow gold
