I'm glad you enjoyed A Moment of Bliss. Everything is going to make a lot more sense in the future. Give it time. :-)
As for the complexities regarding harems, I know it's incredibly more complicated in real life to maintain a relationship with multiple partners. Please understand this is absolutely fiction, absolutely fantasy. I would not condone much of what happens in A Moment of Bliss, or much of my other work, in real life. You're correct that open relationships come with their own unique difficulties and challenges. The wonderful part about fantasy is we can mitigate, or eliminate entirely, these complications so we can reveal in the fun of the scenarios without the complications. I'll dive into some things like aftercare and safe words, but for the most part I want people to be able to experience a guilt-free, consequence-free ride so they can more easily enjoy the magic of it all.
With that said, I do believe everyone should take time out to do research on safe practices and educate themselves about the deeper complexities that come with intercourse. Sex education makes a better experience for everyone.
