It was something that Castiel never did expect when he chosed Jimmy Novak as his vessel..

He didn't know what to do at all, and well, he was in his period, but not Castiel himself.. Jimmy Novak's body was bleeding. It gave him cramps, strange human craving and sometimes he ended staining his trenchcoat.. How great.

Dean normally helped Castiel out, since well.. Hooking up with girls every now and then showed you some tricks. Dean even had extra pads whenever Castiel needed, so normally Castiel would stay in Dean's room for most of the time.

It was another month, and again, his cramps were getting worse, so he went to Dean, who left Cass sit on his bed and get comfortable while he looked for the pads. There was only one sound on the room: Castiel's grumbles and grunts.
