The thing shambles at you out of the dark, its phallus half hard and bobbing before it as it walks, heavy testicles churning beneath its girth. Something viscous seems to be slowly dripping from its tip, until suddenly it sucks back inside. As you brace your shield and unsheathe your blade similarities to a snail’s eye occur to your subconscious. The thing shudders and retches on itself and the base of its cock swells to triple the original girth and continues to inflate until something you cannot fathom emerges from the tip. The beast wails in pain and terror and collapses to the floor.
Have you seen the snails infected by mind-controlling worms? Like that. Something that enters your penis and takes residence in your scrotum after consuming your testicles, it needs the room, it is not small. Penises can be surprisingly elastic, but fuck it hurts. But you don’t process that. The chemicals it’s pumping into your bloodstream just make you want to mate. Make you want to woo. It is always looking for the perfect host, someone pleasing to the opposite sex. It needs you to find a mate. It needs it to be consensual and loving. It needs your mate to care for the offspring once you have passed away from a mysterious wasting disease, right up until hundreds of its kind emerge from her womb amidst screams and blood and madness.
It is not completely averse to you engaging in same-sex relations, it has found that to be a very convenient way of entering a handsome new host.
Cocks can be both invaded and invading. NO ONE IS SAFE.
