I'm probably going to catch some hate for this, but here we go.
I tend to have two types when it comes to women that really just get my dick hard. The first type is the super petite chicks, we're talking like 4'11" and 85 lbs soaking wet. The second type is more in line with the second picture in the OP, though probably not quite as big as that.
I just really, really love chicks who are just a bit chubby with wide hips, long hair and a pretty face. I don't really care about the tits unless they just have really ugly nipples or if one is like a cup size and a half larger than the other or whatever. I like all kinds of tits.
