Thoughts: wimpy little man has a beast boyfriend who fills him up until he's massively pregnant, but over the course of the pregnancy the wimpy man starts to grow larger and larger until he surpasses his boyfriend. Maybe when he's full term he looks at his boyfriend and says "Your turn."
so... so big beast BF can not only make you pregnant BUT also while you're carrying his kid, you yourself bulk up big and strong? to the point where you... gosh ok I could vibe with that probably-- I'm super well, submissive and generally would prefer to be the smaller, the bottom, the one getting impregnated, etc. X) when I was much younger i used to sometimes throw myself into my own muscle growth fantasies but more and more I found myself simply focusing on other guys instead, so yeah This is a neat concept though! Not something I usually think about but I'll put it in the back of my mind for now. the pregnant one *also* bulking up. that is just fascinating. hm.
