*killua makes a disgusted warble in his throat as his transformed cock unsheathes, tensing up in fear of his own alien body. he feels even more sick at the sight of it curling around gon's hand as if it were one of the tentacles that molested him, covering his mouth in horror.*

*he turns his head away so he doesn't have to see what's become of his privates, leaning into gon's side and panting against his shoulder in labored huffs. despite how unfamiliar it looks, the feeling is unmistakably the same as all the other times gon has pumped his cock, agonizing and overwhelming and wonderful.*
