That iptd 665 with Ichika Kuroka doesn't get enough credit. Really good. This movie and maybe even that series (I know iptd 229, and ipsd 018) have some of what I call "rapid swallow" scenes, where there are numerous swallows where the girl immediately swallows as the cum is shot into her open mouth. To me, this is some of the hottest, best gokkun there is.
I've seen hundreds of thousands of loads swallowed and to me, there's too much swallowing that seems "coached" or scripted. These rapid swallows are great because it shows that the girl is truly hungry for the cum. I mean, I enjoy the accumulation of 2 or more loads then a big gulp too, but I feel like there's just too much of making such a point to show off the cum for the camera sometimes. And by now, I know what cum in a girl's mouth looks like.
All that said, to each his own and I still enjoy all of the different styles of gokkun. But does anyone else know of any other titles out there with any of these quick swallows? If you're unsure what i'm talking about check out ipsd 018a. In one of the first scenes Asaki Miuri has about 4 or 5 of these in a row, where on each load she swallows multiple times as the guy is spurting cum into her mouth. It's great.
Btw, I don't know what happened to Asaki Miuri. If you watch ipsd 018 she will remind you of Miki Sunohara on just how happy she is to be sucking cock, getting fucked and drinking every drop of cum. Seems like she would've done more gokkun themed titles but I never heard much more from her in this genre.
