[color=#006FFF]Yeah, I'll pass on mega-boobs like that irl. I usually tell most people this at some point or another, but my preferences of a woman's bust differ greatly between hentai and real life.
In hentai, her bust would probably be a little more tolerable (but still probably too big for my tastes), but irl it just draws too much focus and they go from being enticing to being borderline silly. My ideal bust irl would be something between C (my favorite) to D~DD. It depends on the body structure though, so it's not exact.
In hentai, I'm not nearly as picky and will take any size up to a point--this point being a bit difficult to place a number (or rather, a letter) on, and so I'll just use the example of my limit from before.
This woman is beyond my limit. (And yet, I love the hentai for her perfectly shaped daughter. Go figure.)
