Kinky, eh? Watch Milk Money. That's DEFINITELY for you. more bondage than lactation.
Milk Money started out okay... but that one point in the second episode frightened me and turned the whole plot around. Why?? The series had some good things going for it! =/ Check the spoiler if you want:
The main chick who lactates (since she had a baby that got killed in a car wreck - the chick survived and had all this unused breast milk) ended up killing her own daughter (who the main guy was going out with) just so she could have him for herself. Seriously fucked up. I think there's a third episode (haven't seen/found it yet), but that ruined the series for me...
I was pleased to discover a while back that Milk Junkies (OMG, yes, I mentioned the forbidden hentai, so sue me) now has a third episode out... but NO LACTATION SCENES! Geez, the second episode only had ONE scene, rather short too (although decent). It's a pretty good series, but it seems that bakunyuu-themed hentai is really starting to disappoint me nowadays... we need someone to give us some high-quality, hardcore boob action - lactation, B.E., paizuri, hell, I'd even like to see some nipple-fucking myself. Bondage Game, Ail Maniax, and Deep Body all achieved this, but they all failed miserably in the fact that they were developed around extreme fetishes in general - the really disgusting ones. B.E. and such probably IS an extreme fetish to most... but Kotoyoshi pulled it off in the Shokunyuu series without going deep into scat, guro, etc. although there WAS one scene involving an octopus that I didn't like...
Angel Blade also pulled it off partially with Mistress Phantom Lady, and a whole host of other well-endowed female characters, despite a lot of futanari, there was a HELL of a lot of spooging going on - that one scene (I think in episode 2 - one of my favorite all-time hentai scenes =D) where that one girl's stomach started swelling due to the massive amount of cum that she was getting brutally ass-fucked with was INSANE - and the evil chick says she's only half-way done. I love seeing crazy shit like that. You NEVER see that in real porn! I thought that poor girl was gonna get split open or something, though she DID finally end up shooting out everything that got pumped in her...
but they didn't focus on it enough - it had a lot of unused potential that wasn't even utilized in the sequel series. although I DID like that one short scene (forgot which episode... first or second, i think) where the one little orange-haired chick (forgot her name, she was in the first series >_<; ) was being "breast-fed" by Mistress Phantom Lady. Again - tons of potential for a good bakunyuu theme, but just totally misused. I really think it could've worked... =/
If there are any hentai creators out there reading this, know that the bakunyuu community desperately needs some good material from you! Utilize what I have brought forth!!!
...Also, sorry for the various random spoiler boxes in the middle of my little rave there - didn't wanna give anything away to anyone who might have not seen any of the abovementioned series. >_<;
