Yeah, I have the file(s)- it's only 2; a .cue file and an .img file. If I remember I could never mount the .img file or convert it to an .iso file.
You, apparently, had better luck that I did- if you at least go to play it. 
You piqued my curiosity, so I had a look around. I couldn't find the game itself, but I did find a rip of its CG, if you're feeling nostalgic, heh.
Nope, it's basically the exact same thing in Japanese as well, those katakana just below the English title spell out: "pantsu taipingu."
Damn I was trying to find a CG rip, but it's such a weird name it won't pop up, either that or it's just not popular enough.
It's a Unity game, should be able to rip them yourself.
Maybe this will help:
same, fkcng hell, i tried so many times already, i fuckng spammed that boobs until i cant target it anymore, then spam that fuckng pussy but only thing she does is squirt, holy hell, im so fuckngt mad, and my hands is tired xD
You have to just keep going. It sucks, especially since you have to go at it even more at the next levels.
