Serina Hayakawa has done a few good bukkake and gokkun vids. MIGD-180, MIGD-317 & NWF-220, are imo probably her best.
The only bukkake/gokkun video I've seen by Kokomi Sakura are IPZ-017, SUPD-092, & SOE-674 none of which were great.

:puzzled: Nanami Nanase definitely swallows, in fact I don't own a Nanami movie where she doesn't swallow at least some cum and she usually drinks lots of it.
