[JUR-556] At the end of my mother-in-law’s insidious bullying of my wife, my new stepmother Mito Kana was gang-raped right before my eyes.

Found this

Kana married a man she met through work and moved to the countryside. She is on the verge of breaking down due to her mother-in-law Yurika’s insidious harassment, but she finds solace in the encouragement of her stepson, Hanzo.

Yurika, who sees Kana as a woman trying to cleverly integrate herself into the family and establish her own place, is displeased and, in order to drive Kana away, summons men from Kana’s former workplace and orders them to rape her. After the act is committed,
Yurika berates the weakened Kana.

Meanwhile, Hanzo, who accidentally witnesses the scene, is overwhelmed by indescribable emotions…

Can’t say I understood which actor, if any, plays Kana’s husband, Hanzo’s father.

Perhaps some line explains that he isn’t in the movie?
