help me find this manhwa

i first came across with this manhwa in another site called zinchanm*nga and i cant find it anymore. idk the title and it does not have official translation but it has a similar artstyle with this manhwa: https://www.mangago.zone/read-manga/the_duke_wants_to_have_an_heir/

i believe it's also about a duke, then a warrior/knight came to the duke's castle and they had sex. that duke had sex with its multiple ppl and servant in his castle. that's just what i remember. pls help me find ittt
