Kriniverse
A universe based around the world of "Earth: Tentacle Breeding Ground" in which the Krinis, an ancient progenitor race of tentacle aliens, invade other planets (particularly Earth) to capture all the sentient inhabitants and turn them into breeding stock, milking their sexual fluids for energy, placing them in large meatwall hives, etc. Some captives have their minds altered or even controlled to become thralls of the hive, serving The Queen in their never ending desire to bring others into the fold and share eternal orgasmic bliss.
