Does anyone know of any audio books that involve pregnancy, pregnant sex, belly expansion kinda stuff? I would prefer a female doing the readings. Free or not free!

there is a place like that. https://comicbookbabe.bandcamp.com/audio here the link.

Thanks! She sounds like a dude though lol

Try google searching soundgasm.com with the words impreg f4m.

I found a bunch of female audio clips about impregnation but only one where she is pretending to be pregnant.
Good stuff none the less. You can't download the tracks without using a converter however with the sites link.

Any questions just ask.

Best wishes!
