There are a lot of pregnancy pose packs out there and some of them are a bit…hmm…let’s just say you should probably shut your laptop if your mom comes in the room.
This pack by Elexis at Mod the Sims is “tasteful” and should come in mighty handy for legacy shots and Machinima.
I still might post the “racy” poses later on but I’ll be sure to warn you and give you a link to kittens in case you need a cover. heh
