Maieusophoria (Fetish For Being Pregnant / Getting Impregnated.) [1]

This fetish server is a little bit different: it doesn't have an "addiction" track for the fetish, it's just that ALL of the female monster A.I.s are programmed to just "have a fetish" for being/getting pregnant.

Nothing will make a female monster cum as hard or as fast as having 'risky' unprotected sex with a male member of a species that is reproductively compatible and feeling him pumping rope after rope of thick, syrupy, baby batter right up into their waiting wombs to make them mothers: except perhaps getting a good hard dicking down while their belly is already swelling with children and knowing they are lusty and lovely enough to sway a man to slip them the dick even though they are fat and swollen with children already...

This is not to say that there are no lesbians in this world, just that any female monsters who have no interest in having children, or even just in having more children right now, become lesbians, and any lesbians who do want children will start to become at least slightly bisexual, though often not bi-romantic.

In all other respects, it is more or less the same as the standard servers, monsters to slay, experience to earn, dungeons to delve, all that jazz, but in many cases, "Lay the Dragon" is a perfectly good way to complete the quest to defeat the Dragon threatening the kingdom because she's going to be too busy with being your baby-mama for the next 21 years to be out marauding over the countryside. (And if you play the game properly, by the time 21 years rolls around, she will long since have delivered you a couple of younger brothers and sisters for your firstborn children...)

One final note about the server: to cater to the obvious true target audience of this fetish server, (male players with an impregnation fetish), the population of both the overwhelming majority of "monster" species & monster half-breeds skews 75/25 in favor of females.
