This is really, really fucked up.
You see, just this morning I had one of the oddest, most freudian dream I've had in ages. In it, Alice - the character you posted - had gotten quite drunk with Reimu and taken her home. In my dream, they then proceeded to have quite vivid futa sex, with Alice being the one bearing the penis.
I wish the dream ended there, but it didn't. You see, Reimu ended up getting pregnant from Alice's futa penis, and the rest of my strange dream was them trying to bring the baby to term and learn to come together as a couple.
It was really bizarre, and the whole synchronicity of this 4chan post is just creeping me the fuck out /x/ style right now.
