ReviewThere are not enough swinging games out there and there certainly aren't enough good ones. This is a very good one. Yagami Hiroki is married to Yagami Yukari and their mutual childhood friend is Kamikawa Tetsuya who has a young girlfriend (relative to the others) Maejima Mei . I thought she was a high school girl at first especially because her blouse looks like a sailor uniform and because she and Tetsuya are not married. However, they are a normal pair of couples and good friends, things are going well. They go out drinking together, they spend time at Hiroki's home with his wife together. Normal stuff. Then Tetsuya asks Hiroki to have sex with his girlfriend Mei.

Uhhhh, what? You see, according to Tetsuya, Mei has only ever had sex with him before and she's worried she's not a good lover. You see, if she has sex with Hiroki a few times it could improve her sex life and she can be a better lover for Tetsuya. Hiroki's wife agrees to it, as long as Hiroki is okay with it he and Mei can have sex a few times together. It's to help out their friends after all. You are always able to cancel any time, the game often gives you choices to just quit out of the deal and the game ends. But if you're squeamish what are you even playing for?

So Hiroki meets with Mei at a love hotel, they get some condoms and have sex. He gets home and his wife asks 'how was sex with Mei?' That's an awkward conversation. Still, I love Mei, she's much cuter than his wife Yukari and the immorality of watching Hiroki having sex with a girl with his wife's permission is pretty hot. After having sex with Mei 3 times Hiroki learns the truth. His wife has been having sex with Tetsuya for months. They planned this out to feel better about themselves. The whole thing was a setup. If you choose to keep going the actual swinging game starts.

They come up with 3 rules.
Rule 1. Never have sex with the other's partner without the consent of all pairs. Both pairs will then have sex at the same time.
Rule 2. Always use protection.
Rule 3. Immediately return home after sex with the other's partner to have sex with your own partner.

Of course as the game progresses they break all 3 rules. Near the end Hiroki is even desperately trying to get Mei pregnant and knows Tetsuya is doing the same with his wife. Awesome, awesome stuff.

There are 3 basic endings. All of them good for different reasons.
Ending 1. Full cuckolding. It ends with Hiroki getting more turned on by Tetsuya fucking his wife than having sex with Mei. It ends with Hiroki hiding in the closet to watch the two have sex together. The NTR end.
Ending 2. Full swap. Hiroki has given up on his wife. He and Mei know that they've both been completely betrayed and there's no going back again. They don't care about their partners anymore and drown their passions in each other.
Ending 3. Full swinging. They have more and more sex together. Tetsuya and Mei are having sex in the room with each other while Hiroki and Yukari are doing the same, then they swap partners and keep going. Marriage is a worthless meaningless piece of paper. Full love on both sides. The only thing that could have made this better is if Tetsuya and Mei got married and Mei's first partner as a new wife were Hiroki. Just once I want to see a wife's first partner after marriage be her lover instead of her husband. Damn. Still, this route was a 10 out of 10 while the others were not as great.

< report >I just played this game recently, and sincerelly, above written review contain several strong incosistences, regarding its description of plot. No really idea how reviewer got into those, but actual story goes rather more like this:
You have main married couple Hiroki and Yukari, who have mutual childhood friend in Tetsuya. Tetsuya have his own girlfriend Mei and everyone seems in love and happy. And up to certain degree this is truth. Both couples trully love each other and are completely devoted to each other. This devotion however causes main friction in their sexual lives, which one day Tetsuya addmits to Hiroki, that creates problem in his relationship with Mai. Since he wishes her to be little more aggressive and proactive in bed (Mei herself is completely submissive). And he imagines, that Yukari, is exactly like that to Hiroki when they sleep together. So he ask Hiroki, if he could have sex with Mei and teach her some things that he knows from Yukari in this regard. Hiroki is hesistant, but Tetsuya, who already strongly admires him, has full faith and trust in Hiroki so beg him to do it, lamenting that otherwise unsatisfactory sex life can destroy his relationship with Mei, and he truly don't want to lose her. This convices Hiroki to agree with thing, but only under condition, that his wife Yukari permits that, fully expecting her to decline. However, to Hiroki's surprice, after deep consideration, Yukari agrees and Hiroki is forced to keep his word.
Then, as reviewer above says, they come with set of rules for this agreement, but those rules are actually FOUR and little different than reviewer above says!
They are:
Rule 1: No secret meetings, behinds your partner's back!
Rule 2: No overnights. No matter how late it gets, always come home to your partner..
Rule 3: When you get home, fully report on everything what you did with other person to your partner.
Rule 4: After deed is done, have make up sex with your own partner.

And so within those rules, Hiroki starts having sexual relationship with Mei. They always meet at the appointed time, then go to some private place, where they have sex, and then return to their homes, where they review everything to their partners and have make up sex with them. This then repeats few times. And unlike what reviewer above says, up to this point, EVERYTHING IS COMPLETELY SINCERE! There is no evil intention, or setup from anyone. Just four people who ACTUALLY wants to help each other, just with little twisted method. Even whole thing with use of condoms or avoidance to cumming inside of other's partner, comes more from characters' respect towards original relationships, than anything else.
And so after certain time, Hiroki and Tetsuya are talking which each other about how much Tetsuya's and Mei's relationship has improved. And they conclude, that while still not perfect, it's certainly much better than before. And Hiroki in his mind conclude, that everything what probably remains, is just Tetsuya's own sex abilities and approach to Mei what should improve.
With this conclusion, certain idea sparks in Hiroki's mind, and he imagine his own wife to have sex with Tetsuya and "teaching" him same way, as he "teached" Mei until now. This leads to first game choice, that gives you option, to either ends whole thing now, without any further conflict. Or having Hiroki actually propose idea to Tetsuya. If you choose first, you get first "normal end" and story ends on peaceful note, without any hard feelings.

However in other case, story continues further, and start developing first actual conflict. And that comes from Hiroki himself. When he imagines his own wife to have sex with Tetsuya, he gets torn between two distinct feelings. One is natural jealously, and other basically Netorase fetish, which awakens in him at that moment. Torn between these feelings, he propose Tetsuya to start "getting lessons", from Yukari. But he describe it in rather anbigeous way, to give yourself bit of hope that whole thing will be only teaching on verbal level, despite being fully aware into what he is potentially setting himself.
He then gives same proposition to his wife as well. And word is set, that following day, while Hiroki and Mei leave to have sex on their usual place in hotel, Tetsuya is gonna meeting Yukari in their home, and receive his "lesson" from her.
As Hiroki is done with Mei, he hurries to his home to talk with Yukari and find out what exactly happened on her meeting with Tetsuya. Quickly reviews his own meeting with Mei, and then to his simultaneous relief and disapointment, he hears from her that they trully ended with just verbal teaching and nothing significiant happened.
Following day he meets, with Tetsuya, to hear his part of story. At first Tetsuya's description match that of Yukari, but then Tetsuya regretfully admits, that he actually ended having sex wit Yukari and begs Hiroki for his forgiveness. Hearing this Hiroki completelly frozes and now fully realizes consequences of his initial decision. Tetsuya then humbly ask him, if they could continue with their agreement like this. And Hiroki now completely broken between jealousy and "strange excitement", reluctantly agrees with Tetsuya's wish, but decides go home, to further recover himself from the turn of events. However at home, he gets just more confused as Yukari still acts like nothing happened, keeps telling him how much she loves him and have sex with him as usual. Everything seems to look same as before.

From this story splits into three separate routes which differ mainly in how, Hiroki decides to deal with current situation. And whether he gives into his jealousy or obviously awakened NTR fetish. Important thing however is that in main story, you get to experience events just from Hiroki's POV, and events that happens beyond his sight, you get experience only from other characters' descriptions, recorded videos, or side routes, that are told from different POV.

Routes that are then in play are 3 major routes, and 2 side routes from different POV.
Those are:

- Sincere swinging route
- Netorase play route
- Netorare route
In side routes then you can see Netorase play route from Yukari's POV or Netorare route from Tetsuya's POV. Sincere swinging route then doesn’t have alternate POV side route, since you eventually learn all major secrets here. And as such alternate POV is not needed here.


If I should roughtly describe plot of each route:
Sincere swinging route is vanilla sweet route, which out of three major routes, keep exploring initial swinging premise in most natural and optimisting way. It starts with Hiroki deciding, that sincerity is everything, and convices Yukari to tell him truth. Which she eventually does, and reveals that Tetsuya actually had hidden feelings for her, and those feelings were what actually held him back in his relationship with Mei, and so she decided allow him to have sex with her once, to give his feelings closure and move on with Mei. And that she doesn't told Hiroki about this, because she doesn't wanted hurt him, with what she considered just one-time thing. With that you get second game choice to decide whether enough is enough or you should continue things further. If you decide first, story again instantly ends and you get second "normal ending", but if you decide continue, initial agreement with all its rules expands to Tetsuya and Yukari as well, and both couples now starts openly swinging. Eventually Yukari starts recording her sessions with Tetsuya on camera, so Hiroki (and thus reader as well) can see everything on own eyes and nothing much is left out. After some time, both couples grow so close that they decide experimenting, and slowly canceling one rule after other. Eventually reaching point, where they spends whole day alone with other's partner without any restrictions. During couse of all of that, there is also little side-plot, where Yukari starts avoiding having sex make up sex with Hiroki, but eventually is revealed, that she just wanted drive him into "assaulting her" because she envied how Hiroki was bold with Mei, and wanted experience same boldness as well.
After all this, story skips month later, with both couples still continuing with they agreement, but slowly realise that there is no further reason, to continue with agreement as all issues were solved, Tetsuya and Mei are planning to marry soon and also both couples plan to eventually have children. So to not complicate things further, few days before Tatsuya's and Mei's wedding they decide having one final orgy in hot springs to close whole thing up. However after one round, everyone come to realisation that they genitudely like what their mutual relationship has become. And even Hiroki finds that he developed some feelings for Mei. With that both guys start seeing each other's woman as own approved mistresses and when they have second round, both guys cement new status of their relationship, with openly cumming inside each other's girls. Story then ends with both couples deciding to keep continuing with agreement even after Tetsuya and Mei marry, and postpone its end indefinitely.


Netorase play route is little more straightforward as there are no further choices or secret reveals and events outside Hiroki's POV are left hidden until you read Yukari's POV side route, which unlock later. In this route, Hiroki decides fully give up to his Netorase fetish, and come to realise, that he actually likes Yukari having such secret from him. So instead asking her for truth, he keeps pushing Tetsuya into having secret relationship with her. And this time it's Tetsuya, who provides recording of his sex with Yukari. Which then Hiroki watches on public toilets and masturbates over them. Eventually this reach point, where Hiroki completely forgets on agreement that he made with Tetsuya and just wants watch him having sex with his wife. After while Hiroki decides that video recordings are no longer enough and so they arange meeting between all four in Hiroki's and Yukari's house and Tetsuya brings sake with him. Together they making girls drunk and then they carry each other's partners to bed. But while, Mei quickly falls asleep, Tetsuya and Yukari ends having sex. And so Hiroki silently leaves sleeping Mei and goes near room where Tetsuya and Yukari have sex, ending watching them from behind door. Still not satisfied, Hiroki arranges another meeting. This time just between Tetsuya and Yukari in their house and secretly hides in closet and then watches them having sex from there. Basically scene what reviewer above considered full NTR, except this is really more just Netorase, as after that Yukari and Tetsuya have personal talk, which reveals Yukari continued having sex with Tetsuya just to help with relationship with Mei, and still loves her husband most. So nobody really stole anyone, and Hiroki realises, how much he let himself carry away from their original goal.

Netorare route is just like previous route pretty straightforward, again with no further choices or secret reveals. And once again, with events outside Hiroki's POV hidden until you open Tetsuya's pov side route. Just like title suggest, this is route where things swung into dark waters of actual inexcusable cheating and things are no longer so nice as in previous two routes. Everything starts with Hiroki this time fully giving to his jealousy. And so he decides that he really don't like how whole thing turned out and next day hurries straight to meet Tetsuya and immediately asking him to cancel whole agreement, despite previously agreeing to continue. Such sudden a turnaround obviously disappoints Tetsuya, but he says that he understand Hiroki's reasons. And pleads him at least keep continuing with Mei. So she can keep improving. Hiroki starts feeling guilty, for wanting to ends thing before reaching goal and reluctantly agrees, not wanting to be blamed from their potential break up. But is adamant on keeping Yukari out of this from now. And so goes home where he tells her that argreement has ended and appologies to her, for not consulting such major decision with her before. At first Yukari seems little suprised by sudden news, but quickly move along and expresses joy upon hearing about progress between Tetsuya and Yukari.
Hiroki then continues with his visits to Mei, without Yukari's knowledge, but quickly realises, that like this he basically cheats on Yukari.Eventually full of guilt, Hiroki makes talk with Yukari herself and hypothetically raises the question what she would do, if he cheated on her. Yukari at first jokes about cutting his dick off, but then tells him, that she likely would forgive him, as long he manages to keep it secret, expressing certainty over his love towards her. Hiroki is moved by her words and tries to hug her, but then Yukari strangely pulls away from him and says, that she is tired and need to go sleep. After this, Hiroki is gettig just more and more is consumed with guilt. And on his next session with Mei, he tells her, that he really can't continue any longer with agreement. His words breaks Mei to tears, and she start begging him tto keep going and expresses concerns that Tetsuya may leave her, if they don't keep continuing. This shakens Hiroki so much, that he finds completely unable to do actually end anything. And following this, Mei actively starts seducing him, promising that she will do really anything he ask for, if they keep continuing. Meanwhile Hiroki notices that Yukari starts moving around in far more flamboyand clothes than ever before. But with Mei keeping his attention busy, Hiroki find himself unable to deeply care about that. Eventually Mei drags Hiroki into love hotel, where she convices him to have raw sex with her (used condoms until now) and in the end even cum inside her. In middle of this they are interrupted by sudden call from Yukari, which Hiroki ends quickly and when he is done with fucking Mei, he starts wonder, why Yukari could call him so suddently in middle of day. On that moment Mei says: "Maybe she wanted verify something....Maybe Yukari-san and Tetsu-kun are doing same as we do." Upon hearing that, Hiroki frozes. And realises, that previous day, Yukari actually mentioned something about meeting with Tetsuya. And when he goes home, he starts noticing more and more common points between schedules of Yukari and Tetsuya in last several days. But since he doesn't really have any definitive proof that any cheating from their side actually happened, he can't do much about that. Then next day, Yukari announces him, that she goes to onsen with her friends. So Hiroki calls to Mei and ask her what Tetsuya is doing. And Mei answers that Tetsuya actually have business trip on that exact day. But since neither of them has any excuse to stop them. They have to let them go. Which leaves Hiroki just more frustrated and filled with just more further doubts. On next meeting with Mei, Hiroki drowns his frustration in furher sex with her. But after sex, Mei surprises him with an unexpected gift of memory card with video, that she found recorded in Tetsuya's camera. Hiroki quickly plays it on his notebook. And sees recording of Tetsuya and Yukari having sex in onsen that she visited on previous day. And they have raw sex on top of that. Hiroki watches it breathlessly and Mai soon notices that video gives Hiroki boner. Amazed by fact, that he gets even harder from watching video of his cheating wife, than from sex with her, Mei starts giving him handjob. And expresses her own frustration over not being able to fully satisfy anybody. Hiroki tries to comfort her, but soon in video he sees Tetsuya cumming inside Yukari, and ends cumming himself in Mei's hands as she keeps giving him handjob. After that Mei reveals to him, that she knew about whole situation from beginning and decided to tell to him about it, because she felt sorry for him as he was only one who didn't know anything. She then ask Hiroki, what they should do, considering that their both partners are lying to them. Hiroki doesn't really know what to tell her, not seeing any good way out of the whole situation. So he just says, that he will think about it. Then Mei says that she hope that Tetsuya doesn't get mad over telling him truth and Hiroki realises that Mei even after everything, still values Tetsuya more than anything else. And ends lamenting how everything is his fault, since it was him who started whole situation by offering Yukari's help to Tetsuya. And then keep continuing his relationship with Mei, behinds Yuraki's back. Then when he is about to leave, completely broken, Mei offers him, that she will comfort him, anytime he will want, since she likes comforting him. Hiroki thanks her for offer and leave. Story then ends both couples continuing their lives as before, but surrounded by clouds of doubts, as nearly everyone involved now know, what is happening behind their backs.

< report >Wow! Thank you otakuman007 for the deeper and detailed analysis of the story. The OP really did left out many important context that makes the cheating route so much more heart wrenching.
