I mean... That's what you sign up for when reading a nukige. The whole point of a nukige is to show and have sex for you to jerk off to. Nukiges only care about sex appeal, the little story that it has is to make it somewhat logical or coherent. Fureraba isn't a nukige, it's an eroge.
Eroge - VN with sex scenes
Nukige - VN where the purpose is the sex (and don't care about much else)
Edit: Princess Evangile (https://vndb.org/v6710) and PE W Happiness might be something for you. Or, if you like moe, Wagamama High Spec (https://vndb.org/v17823). Or anything made by Yuzusoft. I also very highly recommend Chrono Clock if you're looking for fulfilling character routes, but they don't include H-scenes. The h-scenes are separately unlocked after completing the respective routes.
