They are not big bolt-ons, they are tastefully understated, but still bolt-ons nonetheless. I'd guess that if she didn't have these bolt-ons, she would just have a chest. She looks like a young Marlo Thomas, or Sally Field, or Elisabeth Sladen. Basically a 1970's look.
I like the look and 0.25 bonus points for the little purple dildo stuck in her twat. 92.5%.
