From the raw at /g/1792630/ba0690db86/?p=2 , an expensive but excellent translation by Tigoris.

The more locked assholes I know are up on the site, the more locked assholes get translated.

There should be a tag for that. But there is not.

@fodfdfkj maybe you can have some luck checking galleries with "chastity belt" and "anal".
female:"chastity belt$" female:anal$
I've tried and I found several without a translation:
/s/b210df947e/2297128-13 and a few others froml from artist:"kurei daisuke$" but they are all heavily scat focused so hard pass for me.
/g/2410486/f85bc0ef73/ and a few other from artist:okina$ which is also a hard pass for me for the material which i believe is also the reason for almost nothing from this author being translated (loli with heavy abuse when not guro).
/g/1812700/321763b6da/
and many others (also i didn't check any full volume)

I'm not sure the femdom tag fits in this context. Sure there other ladies are more dominant than the MC, but this feels way more Maledom than Femdom.

That was very hot. And the ending was peak.

So if I’m understanding this right, he never actually had a child with the main girl?

@Malenk

@Loakalo yea, this is clearly a powerplay by the concubine to have her son as the heir instead of the wife. Anal never makes babies.
