That was really messed up lol. Becoming hard after killing someone (or because of killing someome), it's like those psychopaths in crime documentaries lol. Is it the excitement of killing that causes it?
Yeah. In some cases, killing can be sexual murders, with the purpose of raping, or abusing the victim before hand or afterwards. Here, well the seme did not feel any interest towards the guy, so I’m guessing he got hard because it makes him feel empowered. Killing someone or taking a life is something that fascinates him, something like an addiction. So we’ll see how his psycho develops...
Is this where we'll start getting the sad parts? ༎‿༎
