What nobody talks about the husband here

@lotus_eater :

It is true that her husband himself is indeed very bad/lazy in sex but that doesn't mean he doesn't have the initiative to do it, it just needs a little trigger to awaken his sexual ability.

That is the reason why, the task of a wife is very much needed in giving advice for sex especially if she is mature and experienced, but what happened was the opposite, his wife didn't admit her own feelings and acted like she was immature and confided in her sensei just because she was afraid of putting down her husband who was bad at sex and not building a relationship of mutual trust with each other.

Even though Takafumi's character is not someone who is a chatterbox and always respects his wife's opinion (Listener type), it is really unfortunate if that feeling becomes a trigger for an affair, especially unknowingly Takafumi's netorare fetish created by the sensei himself began to appear when he had to surrender to seeing his wife being raped and knowing the facts at Christmas.

(Here there should be an initiative role from Makoto himself to be honest with his feelings that he really needs Takafumi's help if there is a problem and not wait to ask for help again and follow Sensei's words or even add fetishes just because Takafumi is disappointed with a pathetic erection seeing himself being raped. (Remember Takafumi's words to Makoto before, if he would protect Makoto if Sensei dared to mess with him again), Well, just think for yourself how would Takafumi want to save him again if it wasn't Makoto himself who asked? especially if he was already tied up, and Makoto who had been fooled by Sensei's deadly seduction through his hypnotic words who wanted to prove true love from a partner must have been mentally destroyed, this is very sad for Takafumi who believed in Makoto that much by not questioning the problem. if Takafumi had been rough from the start in asking questions, it might have added to the conflict again, and in fact Takafumi was the cause in netorare but this is not the case.)

That's why there needs to be story development for Takafumi as the protagonist or Makoto who has become the Antagonist if there is a sequel, how does he try to make Makoto honest with his own feelings even though it's too late and tell Takafumi directly what's in his heart not to anyone else so that the feeling of trust can be passed on together with openness to grow a sense of love without having to continue to be made sex and become a slave who is maniacally addicted to the feeling of sex, at least not titled my fault, her choice anymore but her choice, my true love

yeah, maybe that's all in my opinion.

@goyaro21 It'd be nice if there was an isekai where the op mc goes to the ntr world
