Biological Clock Ticking

I’m 34 and not had any children. I’m single and it’s never been something I was desperate for, I just figured I’d know when the time and relationship came. But my biological clock seems to be ticking now. I fantasise a lot about getting pregnant, and I’m not on birth control. What I’m embarrassed by is how much I think about being knocked up by a stranger. Or being fucked by lots of different types of men one after the other so I have no idea who the father of my baby is. I think about being a slut while pregnant too. Being naked with my big heavy breasts and sucking lots of dick. Bending over with my belly hanging as they take turns fucking me from behind.
I know it’s awful and I have to think about the child. I’ve even thought about how I could make sure they’d know who their bio-dad is when they get older. I’ve also thought about how much I would get off on my family and friends asking who the father is while I don’t even know what colour the baby will be.
It just feels so natural... for the strongest genes to breed me...
