You see someone in school and you'd think that's all that is with that guy but when you see him outside the castle, well, there'd be a revelation to be revealed. James Potter/Severus Snape.

Severus Snape is an unusual boy, with unusual life. An accident in an abandoned room with Sirius Black turns his life upside down. Warning: Mpreg, Non/con, angst, M/M, Bottom!Snape, I'm not a native English speaker, complete.
