Tits that are inspired by some of the more frequently found archetypal forms in mainstream porn.

Type3:
Very large with some definite effects of gravity on shape. Pierced nipples, too. Yum! Metallic!

Type2:
Very large and naturally very rounded. Somehow fighting and staving off the effects of gravity to create some truly delicious knockers.

Type1:
Natural tits, with a wider frame/torso. The breasts themselves are wide-set with a very natural shape to them.
