M/M2F4A Wanting to play as the someone who gets knocked up

I love the idea. I am into MPREG and transformation, whatever the case may be. I have lots of ideas how it might happen, but I want to hear your ideas too. That way we can make something we both like. I might be open to a few taboo ideas too if they sound fun. Let me hear you kinks/limits. If there is something I don't like or crosses my lines, I will let you know. Otherwise, let's chat and see what we can make happen! I am open to playing with male/females/futa.

For the most part, my kinks are more vanilla, nothing too extreme. Like extreme bondage, blood, scat, choking, anything that leaves a mark. Let me hear yours and any I find iffy, I will let you know. I only use reddit chat for now. So please don't ask.
