There is stupid, then there is Plan 9 From Outer Space stupid. "Uncontrollable Lust" easily takes the cake here as being so stupid that it's almost fun again. And one is almost tempted to applaud the dev for the unabashed stupidty at display.
The story is an incomprehensible mess about gang wars, corrupt police, secret societies and an MC that for no apparent reason suddenly has magic powers roughly halfway through the story and can teleport and make his arm glow and kill people barehanded. Whatever...
After some exposition and a flashback that is barely comprehensible (Engrish does not help here) the "story" gets going when the MC sees how a co-worker's wife is about to get raped by two creeps (one of them literally looks like the Joker from the Arkham games...), the MC finishes them off with his amazing fighting skills and saves the grateful wife of his colleague.
Once in safety the woman who barely escaped rape does what any woman in that situation will do... she has sex with the MC who then goes on and gives her about half a dozen orgasms, with the MC coming inside her as many times.
Apparently one of his secret powers is that he does not go limp after climax and can keep on going and going and going and going and going... the first sex scene lasts almost forever to the point that you have to admire the dedication the dev put into this first scene.
Out of morbid curiosity I kept on clicking and (with the patch applied from the in game menu) and the VN turns into your typical MC does 'em all festival.
He does the sister of the co-worker's wife (who also needs saving from some creeps), lusts after her mother, his sister (who looks a bit like a dead corpse due to her pallid skin tone) for no apparent reason has had the hots for him all these years and of course the two have sex a few times after almost zero build-up.
There is also sex with the MC's wife of course, with a nurse in a hospital who happens to be the wife of the Joker lookalike rapist who is then killed by the MC, a hotel receptionist who stole the MC's credit card (don't ask), the daughter of the MC's lady boss also can't resists the MC's charms after getting kind of saved from some creep in a bar, the lady boss gets a bit fooled around with as well later and the daughter helps the MC with that because of some blackmail scheme she has come up with (don't ask), then there are a few others, like Scarlett, the girlfriend of some gang hotshot who leaves said gang leader because the MCs cock is just too amazing.
Eventually the MC's daughter and her young female friend enter the scene and of course the female friend immediately lusts after the MC and it doesn't take long before he takes her virginity (she is not the only virgin in this VN of course) and as it turns out the very pretty daughter has secretly been lusting after her father all this time as well and he's her masturbation fantasy (of course), but the VN stops before there is more action between those two.
Shortly before the game comes to a stop there is yet another girl the MC saves from certain rape (well, kind of, the police chief offers her as some token of appreciation or whatever and the MC is supposed to take her against her will to seal some deal or so, I had stopped paying attention at that point) and of course the girl (a virgin) is so grateful for her rescue that shortly after she lets him have his way with her so she can become a woman...
And let's not even talk about slutty looking female police officers, some mysterious Asian lady with magic powers who appears in one scene and can conjure up scythes from thin air, the memory loss the MC suffers from for some weird reason, the female leader of some girls only gang wearing all leather, who has some backstory with the MC, but he doesn't remember her because of previously mentioned memory loss ...
Uncontrollable Lust is plain madness. The "story" is just ridiculous, there is almost zero build-up for any of the sex scenes. I suppose people who have very little patience for dialogue, don't care for the story and mostly use the CTRL key to get to the good parts will have a party with this game.
On a technical level the renders are mostly ok, early on things can look a bit wonky, with dead stares and characters that are clearly just superimposed on the backgrounds (there are no shadows etc), but this dramatically improves over the course of the VN and later chapters look really good.
The female characters are pretty, even if the sister looks like an undead vampire (hot vampire though), there are also various darker skinned women in this game, most of them look Indian or Middle Eastern. Two females appear to share the exact same DAZ model though, only with different hair.
That being said Uncontrollable Lust is one of those VNs that features these grey textured mannequins for many NPCs, sometimes even for those that have somewhat larger roles with dialogue, only the important side characters are fully rendered.
The game has a metric ton of animations which range from ok to really good, they start out pretty ok right out of the gate but also get better as the VN progresses. The dev certainly honed his technical skills. Too bad he cannot tell a coherent story that makes any sense.
So... if you are in the mood for some Plan 9 From Outer Space levels of stupidity then Uncontrollable Lust can give you a fun and silly experience for a few hours. The VN is also not very long, so you don't have to suffer too much and the stupidity ends before it entirely wears out its welcome.
If you want a story that makes sense, characters that are not just sex toys and if you like at least some resemblance of tension and build-up (or even some romance) it's best to avoid this. Chances are Uncontrollable Lust will make your brain hurt.
And someone who doesn't care for any of that and just wants to get to the "good" bits without too much bother... well, have fun! You will probably not be disappointed.
But in my opinion a good VN should make sense and should have characters that are not just paper thin sex dolls. Thus 2 stars from me. 5 stars however for the dev's panache! Ed Wood would probably be very proud!
