The step between non-nude and hardcore.

As an example, centerfold models in Playboy are softcore, as they do not have sex, and usually do not spread their pussy or do masturbation. This has wavered somewhat in the last couple of years, where natural pussy spreads (where the girls open her legs and what happens happens) have become more acceptable.

Good Softcore sites include Glossy Angels
