Secret Journey

They are same hentai parody of Journey to the West. 

Sexy and voluptuous onee-chans can't resist the cuteness of these shotas, they must make them feel good at any cost. Yeah that's pretty much what both of these are about, one is in school with gyarus the other a reimagined version of Saiyuuki, enjoy. 

Both are hentai that are about shotacon material, doing it with big breasted onee-sans of course, one boy and exactly two girls in both of them, you don't need to know anything else. 

Secret journey is full on shotacon, Watashi Ga Toriko No Natte Yaru not exactly, there's no age gap, but the way the guy is drawn, his height and relationship with the female protagonist are really reminiscent of a shotacon hentai, in the second episode there's also a more normal couple, so if you don't think that's enough to have a recommendation there's also the fact that they're both adapting hentai manga and are made by Queen Bee and their rather lacking style of animation that it's basically a cut-out cannibalising the original comics with more recent technology to make it seem less cheap (but it still is), that's it for the recommendation. read more 

What does the first Dragon Ball movie has to do with a hentai with thirty years of difference in the release? More than you'll think, as it's already more of a known fact that at least the first saga of Dragon Ball is based on the novel Journey to the west, one of the most famous pieces of Asian literature in existence, and the first movie of Dragon Ball is an alternate version of that same saga (sure it kinda also mixes the Red Ribbon saga, but it's all the same). Who would think that 30 years later someone would make an adaptation of a manga that's also based on the same famous novel? Sure there's a lot of difference between a hentai and practically a movie for young audiences (with lots of pervy humour, mind you), but they're both loosely based on the same old work, that's enough for me. read more 

So MonMusu Quest is all about that monster girl greatness, but it's also shotacon, the protagonist and the only guy in sight is a little boy, and all the monster girls want to tease him, Secret journey is also a shotacon, the monk is a cute little bastard as well and gets all the action with rapey pervert women, since the characters are based on the ones in Journey To The West, they're kinda not human, they still look more human than all monster girls in MonMusu Quest! Though, but the point is that is related (vaguely) to monster girls. MonMusu Quest! Has better animation, that's all, bye. read more
