Leane of Evil Blade 1&2 might come close to what you want.

Both games have a prologue where you get cucked (though you can avoid it in 2), but the rest of the game is about waging a large scale war while also protecting your female generals and preventing them from being kidnapped and raped into submission by the enemy.

Also, hear me out-
The Busty Elf Wife and the Premature Ejaculator

99% of the game's content is for the NTR route, but there's a musical sting every time the protagonist thwarts the bull that makes you feel like a total boss. The pure route is worth it just for that IMO.

Wait, I almost forgot about Netoria Tactics: Revolution & Nebel Geisterjäger. Both have the threat of NTR, but if you play smart you can avoid it. Also there's decent content for holding onto your beloved.
