POST-462 - Wife caught at the local festival party

It's a story about four married women who end up having affairs due to alcohol and pressure from their partners. The 'husband witnesses' aspect mentioned in the subtitle is actually quite weak. However, in one specific scene, when the sliding door slowly opened, that single moment really changed the level of excitement. I wish they had expanded on that effect more. I also would have liked to see more variation in the content based on individual differences.
