IRL could lead to bad stretchmarks, internal micro-tears, or injury if somebody really pushed it too far.
Fantasy is so much safer and more fun.
>Girl inflates her belly and likes it.
>Tits start inflating along with her belly and she really gets into it.
>Keeps going because it feels so good and she loves how she looks getting bigger.
>Keeps on filling up until she's just a big balloon belly with giant boobs attached.
>Finally has to stop and deflate. >Realizes too late that she's gone way too far.
>Skin is so stretched out that she has to stay partially inflated just to keep her belly from dragging on the ground and to give her boobs some shape because otherwise they'd just hang down past her hips.
>Realizes that she likes how she looks now better anyway.
>Can't wait to try to inflate bigger and stretch herself out even more.
>And also makes plans to do the same thing to her best friend.
