Version Reviewed: v0.11.0
Overview: Talk your way into showing some girls your magic dick so you can bone them and their mother.
Story: You are a bog standard porno game protagonist. Shiftless, bland, and with strong simp tendencies, but you happen to have a gigantic magical cock that hypnotizes any woman who sets eyes on it. One glance and it will fill their every waking thought, quickly increasing their desire until before they know it they are shouting stuff like "fill me all the way up with your baby butter" unironically.
The game is a sandbox and sometimes it's not entirely clear what you need to do to advance a storyline, but it's not so bad that you will necessarily need a walkthrough. The limited number of possible interactions and the inclusion of the girldar make it pretty playable by itself. That said, I have not unlocked all of the content before writing this review so there may be some stuff that requires moon logic.
The meat of the game is a set of mother/daughter pairs. They are all pretty much the same. The daughter doesn't like to interact with boys and the mother is highly protective, but the MC manages to talk his way into the daughter's bedroom where they will of course start to kiss (and then be cockblocked by the mom). Then he'll get back in there again and the girl will just have this overwhelming urge to touch his dick before getting cockblocked again, but now the mother has seen it and she's got the itch. A couple more scenarios where you get cockblocked again and the mother will finally give in to your magic cock and let you impregnate both of them, usually explaining how she started having sex much earlier than the daughter. Unfortunately most of the characters are very two dimensional, and those two dimensions are sluttiness and hornyness.
It sounds like the cock is doing all of the work here and the MC is just there to carry it around, and that's pretty accurate. He is completely useless, getting caught red handed many times because he's a total idiot and basically getting away with it because his dick is so magical that no woman can stay mad at it for more than about 10 seconds.
There is also a subplot where he is supposed to be studying for college in order to get a good end. I had originally though that meant you have to complete all of the content with all of the girls before day 30 and was really struggling to figure out the most optimal way to play the game. But it turns out that at 30 days even if you pass the test nothing happens. It is supposed to unlock a train station that lets you select a waifu for your perfect ending, but none of that appears to be implemented as of this version. Instead the game continues on its merry way letting your penis seduce everyone you meet. Maybe in the final game you'll have to focus on just one girl to get her to waifu status by day 30 as well as getting your grades up? There are three different majors with three different teachers, so maybe you have to replay that part 3 times to see all of the scenes with the teachers? Right now it's kind of a pointless challenge.
Protip: Buy the ebooks on your computer right at the start, especially the female psycology one. They pay for themselves in no time in reducing your grind. Buying the book for your primary subject is also a good idea.
Graphics: Very anime of course since it is Koikatu. They are alright. Certainly made better than most Koikatu games, but that's not setting a high bar. The backgrounds are complete but generic. Overall it is competent. None of the girls have grotesque proportions although the inability of the Koikatu engine to convincingly render anybody over the age of 20 is on full display as the mothers look barely any older than their daughters.
Sex content: There's a good amount of it, but it's pretty vanilla. This game has an unusually large amount of kissing which is a nice change of pace. So many games stick to the strict handjob->blowjob->vag sex->anal sex progression that often feels overly porny. A little romance never hurt anyone. Beyond that however it's pretty much the same progression. Some odd footjobs, thighjobs, boobjobs, etc... added in of course but nothing overly kinky. The most extreme fetish is a little open hand spanking, and their butts don't even get red.
Conclusion: A well made but somewhat unimaginative game. A little more variety and a better written MC would have pushed this up to 5 stars for me. It has a little grind but nothing outrageous. There is even a hint system for about half of the girls in the game.
