I've just been getting into reading fiction, and I'm looking for stuff that fits my preferences, but wow is there a ton of writing out there that's pretty far outside my interests. 

I'm looking for some simpler fair -- stories that feature a couple both very turned on by her pregnancy, bonus points for weight gain / eating kinks, and not super sci-fi or fantasy. 

Anyone have any good recommendations? Thanks in advance!

Ya it’s interesting how hard it can be sometimes to find just a normal pregnancy story. I’d recommend looking through literotica, I’ve found a decent amount of good ones on there. Here’s two of my favorites that fit your description.

Thank you so much I’ll take a look!

The Kristen Archives has a few good stories. One of my faves about a normal pregnancy is Belly Love
