Wow that's perfect example of "American" implant. Even in the remote possibility her tits are real (well Asian breasts are famously fibrous), I still find them not attractive at all.
Esp compared to Saeko Matsushita from @longtimefanold post, with the huge long surgical scar, I think Matsushita's clearly the lesser of two evils. Obvious scar around the base of the tit, compared to tits that looks like hard solid rubber. American implants are optimized for static photos or screen work while wearing cloths and carefully engineered bras, but nearly useless for video for many sexual positions, and certainly terrible to the touch if ever I get to grab them with my own hands.
But I must I admit I never had a close encounter of the second base with American implant. Mostly I seen them on screen (esp. porn) or (old school) Playboy or Penthouse mags. The way my life is going... even I still may play with great variety of female breasts (hopefully), I may never grab a pair as solid as Suzume Mino. Now thinking about it... I kinda want to know how they feel like...
Yeah, surprisely, Saeko Matsushita's boobs look better. There are more JAV newcomers with horrible fake boobs, it's sad. At least, the 80% of natural girls are acting better, have better movies, so I don't miss anything.
