Koibito Swapping

First of all I would like to mention, despite my 4 star rating, the MTL kinda pushes it to 3.5. Another thing is that I am a corruption enthusiast, and coming from that point of view, the corruption is bland "results" only corruption. Short TLDR review One of the main selling points is that all four involved characters are consenting , willing and happy, even in the "NTR" route. There is no mindbreak "I stole your girl" moment, no pp vs PP , the couple stays together and loving forever. All four of them have nice chemistry with each other, even the swapped couples. Game is mostly straightforward, like if they bring out extra non-H aspects they don't dwell on it for too long. But sometimes things can be too straight forward, as a lot of bonding is done offscreen, so the progression of the swapping/ntr is rather quick, like going through bullet points and the translation doesn't help with it. Detailed Review Translation You get the gist of what's going on, but details are lost. I managed to fill in certain oddities by listening to the voice acting, like there's a scene where Rina goes something on the lines of "Do it as you like" but the translation goes " Just love it " like some authoritarian fast food slogan. Content Common Route Series starts off with a common route showing how the couples got into swapping with each other and how close all of the cast are to each other. This is one of the standout points of the series as there's no pushing or goading, all of them consent and are willing, one of them even says "we stop if even one of us is uncomfortable" every time they start. They even go into showing why the main couple finds it exciting, and how they have sex differently. After a few times you will be met with the only choice near the end of the game: Something happens and the MC cannot hangout with the gang as often, however the rest of them still gathered. Suspecting they did some sexy times without him, he choses to Talk about it (continue respectfully swapping) Or Stay silent (become a cuck) Swapping Route Spoiler: For those worried that the MC got cucked once at this point from what I can gather from the voice acting and the vague translation saying she "saw them", all that happened was that the other couple did it while the MC's girlfriend watched After a short talk with the others about the fine line between swapping and cheating if one member is not present, the cast agrees to draw the line and the end credits roll . After the end credits its an epilogue of them going on a double date and swapping in a hotel. A little disappointing at how short it is compared to the cuck route, when arguably this route is executed better, not hating on the cucks but the corruption progression there feels rushed. Cuck Route The MC basically lets his GF hangout with the other couple and they just continue "swinging" without him. At some point the MC finds a video and goes into the typical "heart hurts but why cock hard?" moments. He continues to predictably not have the balls to speak up even when the other girl(not his girlfriend) is asking him if anything's wrong. At some point he finally gets the balls and rushes to the house they hangout at, only to see them going too far with the "swapping". MC realised being cucked gets him off and finally talks about it, and they all happily agree with it and the MC gets reports about what happened with them, and ends with the MC being present to watch it happen while the other girl jacks him off. The couples are still in love with each other, no typical NTR nonsense, its one of those rare consenting cuck stories. Sexual Content I will preface this with the fact that I do not have a cuck fetish, as such I might have some biases toward my main fetish (corruption). Although the initial progress between how they ramp up their sex is alright, like learning from each other and stuff. The first few times they "ramp up" the spice had some minor reasonings, but later on it just happens. If you bother to listen and fliter through the tons of "ah ah ahs" the girls occasionally do some things mid H scene like compliment each other or learn from each other. Sometimes the girls say something in voice but the translation just goes "a ah ah a o" if you really want to catch the small details, nothing major. I felt like the corruption is rushed for the most part, all about the destination and not the journey, but then its because the game never swaps PoV away from the MC. I will put my detailed review of most of the scenes in a spoiler tag in case the surprise is important to some of you. Spoiler: Exact H scenes review All the scenes happen apart from each other, and there's usually a minor time skip between events. Common route It starts off with a vanilla sex scene between the main couple to show they love each other, typical stuff. They get a little drunk and starting showing each other how they have sex with each other after some talks, pretty alright start to the "progress" After some talk about who has the better blowjobs, they swap to prove each other right, we are met with how the couples do it differently, for example Rina puts the dick in her mouth while Mayu kisses and licks the head. At the end of the scene we learn that the main couple uses tissues while the other couple swallows, shown by Rina being caught by surprise as she's held down, while Mayu casually swallows. The jealously of her girl's first swallow being taken and the offscreen sex they have with each other after swapping explains how they start liking the feeling. Interesting part here is they explore why the couples like it rather than just "it feels good" although they do it offscreen, the fact they do intense jealous vanilla sex after is a nice little detail. One thing leads to another and they actually swap partners, and they have sex with each other's partners, after they're done the girls review the differences in how the men fuck them. One nice thing is that both of them have positive comments from the girls, like how the MC is more caring and loving while the other guy is more pleasure focused, and both girls appreciate both styles. I forgot exactly what happened but they decided to swap again but this time they're on the same bed instead of across the living room form each other, so you hear more details about the girls reviewing each others bodies and faces. Not much to say here, just shows they got close. I guess the girls reassuring and complementing each other was kinda cute. Swapping route After their double date, they go to a hotel and then start with titfucking each other's partners, Mayu, being smaller than Rina tries something new like using her nipples, Rina sees this and follows suit. After the titfuck they start fucking each others partners, once they're done, they return to their original partners and I don't know if its lost in translation but they do their own partners raw while the girls touch each other a bit. Some more offscreen sex is implied and they live hornily ever after. Yeah, only one scene, well, technically there's 3CG so its like 3 scenes in one continued event. The girls being more daring to touch each other is a pretty nice way to progress their relationship. The girls learning from each other is something I like from the series, although I wish they could have done something to explain why they're suddenly doing their own lovers raw, like maybe one couple convinces the other, but the micro progress of how they get close and the chemistry between swapped partners is pretty well done too. Cuck route After leaving them alone for a while the MC gets the free time to join the swapping session, and sees his Rina being a bit more thirsty and horny from the usual Rina, this lightly triggers his fall into cuckdom by imagining what happened in between to cause her to turn into this. Quite a bit of the scene is focused on the MC thinking about what she has become and stuff, so if you're into it. Or you can tune it out and focus on the girl like I did. While chilling the other guy just bros without the girls, MC finds a DVD with both girl's names on it, and the fact that Rina normally hates being on camera cracks his heart. Of course he's gonna secretly watch it! Starts off with the girls showing their asses to the screen and the guy touches both of them, Mayu being the original partner starts dirty talking her man and corrupts Rina to join in and starts dirty talking the guy too. Afterwards the guy fucks Rina while kissing Mayu, after they're done, Rina is left there while he goes to fuck his girlfriend, Mayu offscreen. The nice part about it is how Rina gets influenced by Mayu's actions to seek more pleasure, which is using the full potential of the setting for corrupting her. There's some stuff about the MC's heart cracking but I tuned it out. MC rushes to the house to hear moaning and see Rina get fucked and enjoying it, some lost in translation stuff about cumming too much and feeling too good. Then the MC realises they're doing it raw as well after she got creampied. This part is where I feel like things started getting rushed, like they could have shown how Rina gets curious after seeing Mayu do it raw or something, but nope we get the pleasure addict and raw creampie scene all in one. So much lost potential. At this point the MC realises his true fetish. The first time Rina comes back with a report, she was masturbating and researching how to please his cuck boyfriend while waching the other couple fuck (no H-Scene) The next time Rina brings back a DVD with a video of her getting fucked, the MC is surprised by the fact it was her first anal fuck. She talks about how she was trained across some time and how she's gonna be as trained as Mayu who moans when her anus is touched. I felt like they really rushed this like a bullet point they're going through, she mentions how her ass was trained for a long time even with toys, I felt like they could have stretched (pun intended) this one out a bit more, like her seeing Mayu feel good and then getting trained a bit anally, or even the MC being shown a buttplug or whatever at school like she mentions in dialogue. But nope just straight to the anal scene with some spoken context. Again, wasted potential. Final scene where the MC goes to the house and the four of them gather for once in a while, the other guy starts touching both girls and have them compete to see who cums first, winner gets dick. And to no one's surprise Rina wins, while shes getting railed in front of the MC they look into each others eyes while Mayu jacks the MC off because its a least she can do. Well its quite rare to see NTR where everyone's happy and consenting and no evil bastard in sight. But still salty about the lost potential in showing the path of corruption for Rina, but welp the whole series is stuck on MC's PoV for the cucking experience I guess, if you're into that kinda thing.

Koibito Swapping is a VN about a group of four friends and their experience swapping partners. There's a wholesome swap path and a straight NTR path I didn't play. The game has Japanese voice acting for the girls and a decent number of CGs and events. Honestly, it'd be a five star VN if it weren't for the MTL. While I managed to understand the overall story, any given line is going to be mostly incomprehensible. It'd be fun to read this one again with a decent translation. Nevertheless, I guess I'd recommend this one to people who are fans of partner swapping. Those kind of stories are relatively rare on this site, so this offering is good enough.
