Err, it really depends on what you're look for...and what you mean by "delivering the goods".
Mayumi's outfits have generally been getting skimpier with each new video. BMAY-004 is actually new ground for her and starting to push the limits into chaku-ero territory, with some outfits that are almost thongs and panties so small that you can obviously see she's shaven (although surprisingly little CT).
BMAY-003 doesn't have any of that. Most of the outfits are actually quite conservative when compared to BMAY-003 (and oddly enough, BMAY-002 even). Yet in some ways, I actually prefer it. I think she's cuter and more charming in it. Just goes to show that sometimes, showing off more doesn't mean its sexier for some girls. That pink bikini scene is sexy as hell (being shot at THAT pool is always a bonus
), and which guy wouldn't want her hanging off your elbow on a night out in that violet gown at the end?
So if you were hoping to see more in BMAY-003, than no. You actually see less. But if you're asking if its a good gravure video than the answer is definitely yes.
