Should you make all sex on demand or go for a fantasy?

Why not both?

Getting back to the motherboard you start to write up a few changes to reality.

The law of matter conservation no longer exists, and for the last 1000 years or so humanity has been in a golden age of endless prosperity.
Most everything is free or at the very least cheap to get. Being in a post scarcity society has made for an amazing world to live in.
95% of humanity are workaholics so progress never really slowed down on anything. Odds are you could just stop working right now and no one would bat an eye at you since most of what you can get is free with the exception of land.
The reason why sex can be on demand form most women is because humanity needs more humans to progress even further. Also, all women in this world gain strength, magical power, even more beauty/bigger every thing (giant women are a thing and they are the closest to being actual immortal goddess in this world), and become addicted to sex quite easily with most mother teaching their daughters the ins and outs of sex once they are if age.
Humanity has started to explore the star as of a few decades ago only to find more worlds to call home. Some of the giant women even teleport occasionally to other worlds just to both help with moving people and suck on hundreds of dicks all at once.
In this new reality it is perfectly fine to pull down a random woman’s pants and start fucking her, she’ll actually thank you for it.
Lastly, the amount of times you’ll be accosted by a woman to impregnate them and make them into a single mother should be no less then 10 times a day due to the new reality compiling any women into raising a child in what is effectively paradise.

You screen shows a loading bar and in a few seconds you can feel the world around you changing. The apartment you are in sudden gets to be huge and some knowledge goes into your head telling you that space altering magic was used to make it that big.

Stepping back outside you are almost immediately jumped be a ten foot tall Amazon sex goddess who ask “Hey the big man, wanna fuck me hard and long? I just master dick e binging magic and I can give you a pocket dimension to store it later in.” End her sentence with a lip bit.

You whip out your dick and she gives a cheer before getting on her knees and starts with a blowjob that actually feels a little weird. Soon you start to feel more and more of you dick and you realize she’s growing you dick! You have now gone from a 8 in dick to a 3 foot long snake in your pants. She stops before you cum, giggles a little bit, and you feel yourself being levated off of the ground as she bends over and puts her hands on the nearest wall.

You get lined up to her pussy and HOLY FUCK! SINCE WHEN DID PUSSY FEEL THIS GOOD! She uses her magic to piston you in and out slowly getting faster. Her pussy walls both vibrate and suck on different parts of your cock making you head spin. About 30 minutes pass on by and you can feel yourself start to unload into her womb. Setting you Dow on the ground she giggles again before kissing you on the lips and saying “Thanks for the new baby daddy~ I’m Sarah by the way and I hope to fuck you again soon~!”

Holy shit you made a good decision.
