Ok, ok. When you start ranking boobs, ya know I gotta weigh in. The people need a ruling!
Yoko does have a great set, no argument there. And I had a great time with her and agree she's somewhat underrated. But given what a slut you are, top 3 all time? Really? That's pushing it. I dont think I can justify putting her in my top 10. OTOH she IS comfortably in my top 20.
But, let's narrow it down some. Let's limit this category to all natural, on a FS Asian girl, who isnt "thick" (so we're excluding Natasha and other girls in her mold) and actually has a waist, and who gives decent service. THEN, I can accept reasoned arguments that she is #3, though I'd probably put her in the #5 - #7 range myself. Just this year, Arie and Love (the one I reviewed at P31 that I know you also saw at 3838) have been available, and are clear #1 and #2 in that category. Recently, I'd probably rank PH Molly and Isabella, as well as at least 2-3 long gone girls not worth naming anymore, ahead of Yoko. I'd add PH Stella and former Sally's Sherie to that same tier. But it's close, so it's not outlandish to give Yoko the edge among that chase pack. I think you give her boobs extra points because you like her! Which is fine - she's very likable. But if we're properly dehumanizing the girls and breaking them up into their component parts, ya gotta do it right! No sentimentality allowed.
Also, she is a MILF type, if not literally a mother. But emphasis on the ILF part! My guess is mid 40s, passing for mid 30s.
