Plot

Yuuki Nono and Tenma Yui star as neighbors in this couple-swapping JAV. The opening scene gives us a glimpse into the couples' home (and sex) lives: Yui's husband has a high-paying job, but he always cums too quickly, leaving Yui sexually unsatisfied. Meanwhile, Nono's husband is in a low-paying job, but he's a stud in bed and doesn't cum even when Nono is tired. One day, Yui and Nono get talking and they realize that that both their wedding anniversaries are actually on the exact same day. Back home, the wives convince their husbands to celebrate their anniversaries at a hotel - a significant place for the both of them as it's the same hotel they got married in years ago.

On the day of their anniversary, the couples check in to the hotel separately and the wives surprise their husbands by revealing that the room is actually a connecting room, and their neighbors are in the next room. They order in some room service and start talking over some wine. Over dinner, Nono mentions that she would like to get to know Yui's husband better, and leads him to the next room, and that's where the fun begins.

Theme

Couple-swapping in JAV is usually driven by some form of negative emotion - jealousy, guilt or anger, but there's no sense of any of that from any of the participants, so this is about as wholesome a NTR plot as you're going to get. The secret sauce though, is the connecting room. I've never seen one in a JAV ever, and it was used so masterfully here to enhance the plot. From the moment Yui and Nono opened the connecting room door, you could tell that they were going to have sex in that doorway, and that scene delivers at the end. They could have done the same plot in the apartment set, and it wouldn't have hit as hard.

The Sex

There's a good variety of sex positions both during the couple scenes and also the 4P scenes. Props goes to the cast: Tenma Yui's raw sexual energy makes for a dynamic sex scene where it feels like she wants to devour (not literally) her man. On the other hand, I love Yuuki Nono's quiet slut character - when the clothes come off, she shows that she can be just as dirty as Yui. Both girls dominate their scene in different ways, but when they come together for the 4P, neither outshines the other, so there's a good balance in the cast.

Final Thoughts

With almost 30 minutes spent building up the story, I can imagine that some people gave this a pass for being too boring. Overall, it's a really solid JAV - the build-up ties the whole thing together for that final 4P scene (which IMO is worth the proverbial price of admission alone). Even the two sex scenes at the start - poorly lit, barely any action - serve the purpose of contrasting with the later scenes in the bright hotel room.

The cherry on top is that closing shot when Yui and Nono walked out of each other's apartments - I had to do a double take and rewind back to the first scene just to make sure I saw what I saw. If you missed out on this for whatever reason, consider giving it a watch.
