The belly, of course. But so many aspects of pregnancy are sexually attractive to me.

Belly. The hugeness, the roundness, the belly button, the movement. I love the boobs, too, but that's secondary.

The belly of course. Bigger, better. And instantly turn me on, when a pregnant woman wear a long dress showing her big round belly.

I agree with Maiesiophilist, the bigger the belly the better it is. though i also like when a preggo has big boobs

uuhhm the whole pregnancy with everything included... why should i choose? well, the motherhood, this for the baby and to feel the baby's moves. uhm, the belly, too yes, but the belly is not everything. but i see it from the side as a woman, of course. maybe most guys see it different.

Love a Big and Round belly!
and i love the fact that the girl changes the habits in her life because she is pregnant!
example:
- she can´t move so fast, because that makes her unconfortable
- she can´t sit down like she used to because of her big belly
- she can´t do things easily anymore,(talking too much, moving around, sex) because she gets out of breath
- she feels / touch her belly constantly and sometimes she expresses discomfort in her face or looks at her belly to see the baby movement
- and sometimes pregnant girls have braxton hicks contractions, they have to calm down for a minute and stop what they are doing

Me gusta todo. Desde el principio, observar, día día su progresión. El aumento de su glúteos, barriga, tetas ,amplias y pesadas y el ensanche de sus caderas.-... TODO.

Todo en ella es fascinante.
Dicho ésto, Me fascina la expansión que día a día la hacen bella e irresistible.. Sus caderas ,sus glúteos y todo en ella

La evolución diaria de su cuerpo. Es pura fantasia

i think for a lot of women, pregnancy (even the little 'just started showing' bump) completes their form. the face fills in a little, belly rounds out, hips get wider, and ofc the boobs.
then on top of all that, at the end when they start contracting and moaning my brain sees it just like sexual moans, and watching them open their legs wide and rub their belly as it tightens up and changes shape on its own... and sometimes they have to go up and down on the ball or rock back and forth like doggystyle, its like their body MUST do all this sexy shit at the moment its looking hotter than ever too... its all just the hottest, most amazing goddamn thing <3
