This trope of the MC holding the wife's hand as she's getting fucked feels very new to me - I've only seen it in a handful of jav, and very few doujins - and I personally enjoy it a lot. I think it really strikes at the core of the fetish for me. It makes it so it's all about the two of them. He wants to see her get fucked without feelings of betrayal, and she wants to make him happy. So he's right there, getting a front row seat, while she tells him how much she loves him. I find it hot as fuck.
Of course, the other types of scenes are hot too, so I'm not saying it should be all handholding sex. But for the first time sex, this might currently be my favorite way to go.
