Damn, what version was this maybe we can find it in this thread itself? Really want to play this version! What other content was available in this version?
...Well, to give some examples:
1) After appearing on the Mountain Top, he found some unclaimed panties on the other side of a log. Having nothing to wear, he went to pick them up. While reaching over the log buck-naked, a demon wolf appears and [Attacks] *cough! cough!

* Making him 'walk funny' for a while - and setting the main overtone for his corruption after that.
2)The Elf Mom that gets tapped by the Werewolf on the Mountain could give birth to a corrupted pup (Black Wolf) instead of getting purified (Brown/Gold Dog/Wolf) by the MC, depending on the choices you made while camping. She would be further corrupted over time, and more and more demon pups (black wolves) would be born
3)MC could take the Elf's place for things like the Werewolf scene. Or he could choose or force a party member to lure the Werewolf away, taking the Elf Mom's place on a log to the South-east of the Werewolf's original scene. (If the MC took her place, he could go back to the log cabin and meet the Werewolf in human form during the day later on. Otherwise, the MC could 'give' his party to the Werewolf in the Caverns to increase his demon wolf population. This is the first Werewolf (Black one), not the smaller, gray werewolf on the Purple Witch's mountain) Again, if he prepared himself with a slime or five before taking the Elf Mom's place, he could have young werewolves, instead of pups.
4)He could replace the Mayor with the Two Goblins hiding in the caves near the Dock Town by wearing different versions of naughty underclothes found, won, or purchased around the game. If he let the Slimes do their thing before joining the goblin for a threesome, he'd have kids - rinse and repeat, filling the caves with new goblins.
5)During the (Panty) Goblin moving into your home with the Elf family, he'd help the Goblin slowly increase the goblin population with the Elves (and didn't even leave the poor chickens alone...). This leads to one of the subplots of the invading arming attacking and trying to purge the starting village later (same happened if the demon wolves took over, corrupting the village).
6) The MC gets the ability to freely change his gender organ's form through potions while male, and later gets the transformation option to become fully female - long blonde hair, boobs, etc. - (but can change through the various transformation types). (Note: This is actually what leads to the original true game end. Remember the F**k contest between the Merchant Elf and the Mom Elf? Well, if he gets pregnant normally, as a female from that 'toy', then this leads to the true ending of the game. Turns out the angel that created him, created him as her clone to see if the world was worth saving. If it wasn't, he would give birth to the Ultimate Demon. This turned out to be the reincarnation of the Demon King the Angel once worshipped. But to bring him back she had to give birth to him - thus creating the MC, you, as her replacement. Oh. Did I mention that the Angel was also the Evil Demon Queen? And that the 'Toy' WAS the Demon King, or rather all that was left of him, containing his soul? Anyway, this could only happen if the MC was thoroughly corrupted and road that toy like a cowgirl in a rodeo. The Angel/Demon Queen/Mother of the Church explained all this afterwards.)
7) The baby dragon eventually took you to the dragon village along with the girl from the dragon clan. Turns out the dragon was a pure blood, and the girl was an exile and a mixed blood dragon.
Just the things listed above were a HUGE time sink and subplot path line in the game leading to even more game content. This isn't even mentioning the optional 'taking over' of the pigmen's ship via intimate means (required a necklace that could only be found while on the ship). Or the intimate sequences with nearly every living thing in the game, such as the mushrooms, etc.
As said (and HEAVILY inferred), most of the content was removed...
