After her husband loses his job, Eri moves in with his family, only to discover a twisted tradition where wives are shared. When she catches her sister-in-law Rion in a compromising act with her brother-in-law, Eri is thrust into a world of forbidden pleasure and moral decay.










The story was good, and both actresses were sexy with beautiful, massive breasts. The final 5P scene wasn't as bad as the reviews suggested; watching their breasts bounce while doing doggy style on both of them at the same time was incredibly arousing.
I watched this in 2021, about 8 years after its release. Given it featured two top busty actresses from around 2013, my expectations were high. However, rather than Eri Hosaka's beautiful breasts, my eyes were glued to Rion Nishikawa's (likely natural) massive chest, and in the end, the scenes that actually got me off were hers. As other reviewers have pointed out, the final 5P scene, which should have been the highlight, was poorly structured, so it might be weak as a tool for self-pleasure. It was a work that reaffirmed the destructive power of Rion Nishikawa's bombshell body.
The tradition where you can freely take the women of the house. Rion is taken by her step-brother, and Eri is violated by her step-brother. Rion, who is completely used to the tradition, is erotic, and it's exciting to watch Eri feel pleasure despite her confusion. As the title suggests, both have huge breasts, but when they stand side-by-side, Rion Nishikawa's definitely stand out. That said, Eri Hosaka's are beautifully shaped. The final orgy scene with four breasts bouncing everywhere is quite a sight.
Features two gorgeous, fair-skinned, busty performers. The sex is quite intense; the scene where they're both being hit from behind while their massive breasts bounce wildly is truly impressive. However, the dramatic plot gets in the way. It would have been more exciting if it were just a standard swapping scenario where two couples trade partners, switch back, and get cuckolded by strangers in the process.
*Even though they used so many actresses, they focused on the story and the actual scenes were poor. Depending on the development of the story, it could have been a good work.
