So I (M 29) have been a bull for a certain couple (M 30/F 31) for a few years. We first met on a camping trip while they were engaged. They’re currently expecting a child together and they invited me to have sex with her while she is 8 months pregnant.

It felt really special that they wanted to involve me in something so intimate, but at the same time it felt weird. Maybe it’s me making it weird, but I just couldn’t get over feeling like someone else was in the room with us. I’ve seen diagrams of third trimester pregnancies before, there’s like a fully grown baby just above the cervix, just below it my dick would be swishing around in its mum’s vagina. I kept feeling like I was poking its head, I swear I even felt it move at one point. We didn’t use condoms since we know each other really well at this point and there was obviously no risk of pregnancy. I finished inside her like I usually do, but this time post-nut clarity hit me like a ton of bricks and it just felt wrong.

How do others view pregnant sex? I heard someone say he would never do it because it’s like involving an unborn child in a sexual act. I know it’s perfectly normal for a lot of pregnant couples to still enjoy sex, but is have sex with a woman who’s carrying another man’s kid a boundary that shouldn’t be crossed?
