Thread for cock parasites. If you've played CoC and run into the worm mobs or the infested hellhounds in the mountains, it's just like that—worms hanging out of the dick and writhing around, plus ejaculating worms; or the process of being infected by worms. (Pic used is just what I could find quickly.) Can be male or futa; gender isn't the point and anyway this is rare enough I wouldn't be picky. Weird discharge (caused by the worms?) or worms in the butt as well as the dick are also good. Long, earthworm-like, whitish worms preferred, also the infected person enjoying the experience but not over the top ahegao, but I'll take what I can get.
