8 XXX : bimbofication

No, they're perfect. Leave them alone.
I think you are still young and are blessed with large perky breasts. Just make sure you show them off a lot. (Boob window tops are my fave). You can go larger in a few years. There are plenty of other things that you can do to become a perfect bimbo. How does your ass look? Make sure you do plenty of squats. Get nails done. Without seeing your face, maybe you want lip fillers or a nose job?
If you go for enhanced, make sure you go to a good surgeon, and go BIG. Nothing like a huge pair of fakes to show off a bimbo! And then piece them. Maybe even double-barbell piercings. Also, get a mani. Acrylic nails :)
Those are the nicest titties I've ever seen.
Good so far,maybe eventually go bigger
They look amazing. Size, shape, perkiness, they are absolutely sexy. I think it will be more about if you decide you want the aesthetic look of enhanced as you progress to being more of a bimbo.
