JAV Porn – What’s the most brutal and realistic JAV cuck movie you have ever watched ?

I'm looking for plots of a similar kind.

I'm not talking about husbands who have a cuckold fetish. I'm talking about the kind of movie where the husband loves his wife dearly, but she still cheats on him, and then later regrets it.

My personal favorite is DASD-351. The plot of this movie is tight and has a satisfying climax. Yui's acting is really good, and she genuinely regrets her actions of cheating on her husband.
