My personal dream scenario would be a medieval world where I am the monarch of many lands. My rule would be lenient and hopefully I would prosper with great diplomacy, but my toll would be beautiful young ladies for my darker side.

I could torture them in endless ways in my dungeons, but that's kinda vanilla and boring. I most probably would have some hunting grounds disguised as some kind of royal park full of distractions for the tribute women to roam freely(they wouldn't know their fate, they'd only know they've been sent to serve me). In these parks I would either ambush and brutally kill them or seduce them only to kill them while having sex. I'd also probably use enemy spies or women of my enemies in dangerous games and side shows. Using ladies for target practice is a favorite fantasy of mine, but there are other things like the arena: a fully armed man (me or a servant) would fight multiple scantily clad women. I'd probably also have some kind of tournament once a year where warriors from across the land would try feats of strength (and get rewards in gold or slaves) like lopping the heads of as many ladies as possible from one blow, hitting specific body parts with bow and arrow from big distances, smashing heads by throwing war hammers and whatever I could devise that would imperil women. I'd probably participate in those tournaments disguised, not to attract too much attention.

I'd also probably have a beautiful, too beautiful to hurt wife that I'd love in all the "normal" senses of the word. Entertaining her with parties, giving her gifts and ofc. pleasuring her and myself with the wildest sexual orgies.

Now... if I were to go full fantasy(which it already is) I'd also like to imagine that this world had mythical creatures (trolls, dragons, wyverns etc) which I could control with the help of my court's council of sorceresses (which I wouldn't ever harm since I have a weak spot for them). Perhaps through the practice of theriantrophy I could take control of such creatures and prey upon damsels. It'd be pretty neat to posses a dragon or even a bear or tiger and maul a bare maiden to death.

I'd probably also have my own private deluxe brothel with the best looking whores from all across the world, which only I and my closest friends could use, and perhaps some of the people I'd like to stay in good relationship with so that I may reign. These women would be treated highly, almost like royal ladies, but without any of the other political privileges or power. They'd be like my own personal reserve of fun after great accomplishments. Of course, from time to time I'd take one of them to my castle's quarters and delight in her forms and beauty before ceasing her existence when she expects not.

One last thing....I'd probably ban religion and execute practitioners, for in my kingdom I shan't tolerate such nonsense.

Alas, I could elaborate on this fantasy a lot more, but another perfect setting would be in the far future where humanity would already be integrated in the galactic society (if there is such a thing). There, in the vastness of space I could probably get into galactic slavery and exploit other alien species that resemble our own. ( I blame playing too much Mass Effect for making me believe there are beautiful alien babes out there, one of my favorite franchises doe, along with the Witcher series which inspired some of my medieval themed fantasies).

Although much of what I've said is at fantasy level right now, I believe that in just a couple of decades we'll be able to achieve realistic simulations and fulfill most of our desires. (and that's why I plan on working in AI development(so I can make believable restricted AGI's to play with in my fantasy worlds) and virtual reality gaming as a side hobby)
