it is not the pregnancy itself that is hot, but rather how that pregnancy came to be; who did it? who is it done to? why and how. Pregnancy and impregnation go in hand with each other. Although not always, it is seen as the final step in the conquering of a woman. She willingly giving all of her self to you. For her to desire you so much she has designated you as the only man shed want to reproduce with. A title not given to any men by most women. In return you feel loved and desired as a real man. To become a father, the 2nd most important function of a man. You get to see her belly swell month after month with your child in it. The beauty of her fertility. Her breasts enlarging, her areolas growing and darkening, her body gaining a bit of curves in the right places.
Now combine that with the taboo and depravity and you get what most of the top porn games consist of: Harem pregnancy with your hot blood relatives. And thats just the tip of the iceberg. Add impregnation/pregnancy to other existing kinks and youll start to see the patterns. It is all part of the fantasy we can only get in consequence free fiction. A line pushed further and further back simply to get your rocks off.
Some guy here mentioned he didnt like it cuz it made him think of the life inside and it made him uncomfortable. I understand that, its a valid argument. A lot of men see sex just for pleasure which is quite saddening and they rather skip the whole pregnancy deal if it comes to that.
NO disrespect to any man that thinks like this, but if this is your philosophy then I really believe you either still have some maturing left to do, or you simply failed to grow into a proper adult. Which is fiiine. Reproducing aint mandatory. Some have the choice and never do so. While others yearn for it, but never will
