harem [M4F] A true breeder from the stars

Just like any world born to just a touch of power and oddities, a pod falls from space and blah blah blah. We've all heard the classic alien from space with fantastical powers, difference is this one only has one goal built into his very DNA since birth - Pure constant endless breeding. It was all hidden under instinct and human morality but now at his physical apex and the urges burrowing into him there is no choice but to conquer and breed 

Whether Hero, Human, or Heartless Whore they will all be his broodmares to rebuild his race and satisfy his every need.

(Sounds raunchy as all hell but I was thinking more slow burn, better harem more thought out and tons of variety as we move through a world we build on fucking, cliches, and corruption into things we both enjoy)
