We're more intelligent beings & we're taking over your beautiful
planet. You stupid, greedy humans are doing such a horrible job with it
you don't deserve it. Pollution, war, cruelty...your air,
water, plants & animals all being destroyed. This ends now. We will
take care of your planets resources but we need some of your abilities
to survive on your planet, to be able to breath the air,
etc. So we are collecting your sperm to create a hybrid with your
species & ours, taking the traits we need, like your lungs, for our
survival. We are a female led species so will keep most of the
females alive on your planet. The only men that will be kept alive will
be those who can produce the most valuable sperm. So stroke like your
life depends on it stupid human male & hope that your
load is impressive enough to save your life.
