You get harder when you're tired?? I feel like that's just made up but I'm a bit too afraid to google it. Can anyone verify?

 

[Atlas47]

@FluentInManganese It does it for literally any reason it can. Every situation and variable that comes up has a 1/3 chance of activating. Anyways yes, that's more or less correct.

 

[FluentInManganese]

@Atlas47 oh, interesting. Thanks for the info!

[marioforever97]

I came when they strip him like that
I wonder what would his friends (especially the ara-ara Miyo) think if they see his dick instead?

I always love these "dangerous gender reveals" scenes
