I want to see a continuation of this one. Especially if Samus finds Dark Samus and Dark Samus is determined to out do Samus and tries to take her whole cock into her mouth. Or Samus finds more fertility upgrades and starts fucking every pussy she comes across to leave a bunch of chozo/human/whatever hybrids behind her.
I'm honestly a little torn with this one, it's one of the ones I'd like to see expanded into its own fic. But I also think it would have been interesting if Samus had been able to see Dark Samus make her entrance and transformation so she would know just who was dominating her. Still, a good upgrade! Though I think Dark Samus should keep Samus for herself.
Enjoyed chap5, though could have used a longer sex scene. I really want to see Dark Samus enjoying her prize.
