This is one of my kinks. Here are some on this site from My Library:
Ascension of the Alpha Male and other stories by GoldenMage
Atlantis by Warlord
King of a Distant Country by Smilodon (unfinished, I think Smilodon passed away)
I think all the 'Reward' stories (eg My Reward, etc.) include harems. Just do a title search on 'reward.'
Most of my stories (most unfinished after I was diagnosed with cancer)
Many more by different site authors. If you have access to the Stories On Line category search function there is a 'harem' category.
Not necessarily inherited, but a lot/nearly all of the Master PC stories involve harems. You can find most of them on JR Parz's asstr page here:
The Erotic Mind Control Stories Archive has about a page and a half of stories identified with the harem tag using the Svengali search engine, which can be found here:
