Pregnant fetish
I've known for a while that I'm VERY attracted to pregnant women. I do watch them in porn, and once I even briefly dated a pregnant woman (long story). Most intense orgasms I've ever experienced. When my sister announced her pregnancy I thought it wouldn't be a very big deal. I was wrong.
Of course I would never tell her or act on it, but I've been obsessed with her pregnant body for months. I can't resist the urges to jerk off and fantasize about fucking her and sucking on her lactating breats while I cum inside her, but I feel terrible afterwards. I can't tell anyone about this, so at least I can write it here.
This site is good for letting out feelings that you can't normally share. Some women become very sexual when pregnant and with hormones all over the place you might just stand a chance.
Is your sister with the father of the baby?
