Speaking of 'Ryn, I can't speak for anyone else, but my desire to see her pregnant isn't because of me being squeamish about my character getting pregnant, or Elthara being a surrogate making it "not our baby" or anything like that. If anything, I'm sure it will be fun to have more threesomes with them and top Ryn from atop her girlcock. But I think it would be even more fun to see our princess/queen grow even bigger and curvier as she carried our baby, and since the baby would be above her prostate, you just know she'd probably be hard and/or leaking pre all the time and it would be amazing to be able to tease her about it while treating her cravings. With dick and/or pussy.
But, that won't be happening because Etheryn is already a Gordian knot of spaghetti code it would probably take a fundamental overhaul to untangle and letting her get pregnant somehow would just be another complication. Ah, well. We adapt.
