Mutual growth where my incredibly sperm-dense cum makes your body swell and tits expand until they're bursting with milk, and drinking that milk makes my balls churn louder and fill quicker...both of us starting to grow in tandem in an infinite feedback loop...
Love it when these bimbo sluts start drooling uncontrollably because they've realized the veins on my massive shaft are thicker than their little shrimp boyfriends entire microdick
Need me a size-obsessed broodwhore that I can turn into a living incubator...just pumping generations word of my seed into her fertile womb, my hyper cum strangling her ovaries into submission
