So my gf and I have been together for a couple years and a while ago I basically explained to her how I’m turned on by the idea of me getting her super pregnant and I cant wait to see her heavily preggo. I explained it  from the angle of how I like the idea of everyone seeing what I did to her and the transformation her body is gonna go through. She had a positive reaction and said how she cant wait. (We arent ready yet and prob will be a few years til shes pregnant.)

Since then I like to mention it during sex and ill always randomly say “I cant wait to get you pregnant”. Also constantly joke about how huge shes gonna get. She is very excited to get pregnant too and enjoys talking about it with me. She’ll say things about how I wont be able to keep my hands off her, how shes just gonna wanna be naked all the time. Shes also looking forward to having a huge bump. She’s said things about wanting to do a nude photoshoot and how shes gonna wanna show off. Multiple times shes also brought up how she plans on wearing super tight clothes and will try to squeeze into her pre pregnancy clothes and wont mind wearing them when they barely fit. Her reasoning being she doesnt like maternity clothes and wants to show off her bump instead of trying to conceal it. (Hearing this makes insanely excited). 

Since we are still a bit aways away from actually getting pregnant I wish there was a way I could more incorporate my fetish now with her. Open to suggestions if anyone has ideas. Maybe show her my morphs or her? Or have her try padding.

Feel free to message me or reply on this thread if you wanna chat about it or hear more.

Invest in a prosthetic?

But congrats my dude. Life with a GF that gets into it/plays along with it makes your sex life insanely easier, and hotter.

My ex would ask me to rub lotion on her belly and talk about yearning to be pregnant with twins or triplets. Was fantastic!

Congrats, sounds like you've got a winner. I'm personally not into fake bellies, so when I want to get some belly action during sex my wife will do some food/drink stuffing right before. She doesn't get as big as a fake belly, or as big as she was when she was pregnant, but at least it's her. She also has a couple of shirts that are way too small and will wear those during sex to exaggerate the look.

One word of caution, though: be careful about making pregnancy roleplay too integral to your sex life. If it turns out y'all can't actually get pregnant someday it will be a real sore spot.

Update: By now she’s super comfortable talking about it and knows how turned on it gets me. During sex we’ll take turns sharing fantasies and I've been focusing on the idea of other guys approaching her, taking pictures of her, and touching her in public when shes pregnant.

I’m looking for new fantasies to describe and things to say regarding when she gets massively pregnant.

Anyone have some ideas for me?
Open to message about it as well

My gf would always inflate her belly for me during. Since she got pregnant i can confirm nothing beats the real thing but sometimes when she was particularly full especially she could put on a significantly large bump just by pushing out. Definitely would recommend if youve not tried. Your gf seems vry chill so maybe broach that with her.
In the early days she would send me pics of her pushing her belly out. Honestly best thing ever.

A fantasy I love to hear from pregnant women is that they’ll grow so big that they won’t be able to get up anymore. All they can do is lay there and be fed and fucked by you until they go into labor

One of her new favorite things to focus on is how people are going to be taking pictures of her when shes pregnant and getting hard looking at her. Reminds me of the candid thread here (maybe she’ll be posted there one day lol). I call her my “pregnant girl” and she tells me she’s going to get pregnant every year. Another fantasy we’ve talked about is how she’ll visit me at work in clothes that barely fit and everyone in the office will stare at her. “When they rub my belly they'll have to slide their hand under my growing tits”

A fake belly could be an option if she's keen, cheap maternity clothes and see if she's interested in pretending.

Taking her out pregnant would never get old I feel

I’m looking for more things to say to her when we’re having sex, please reply with suggestions
