You and Hellboy had grown pretty close, close enough that you knew his emotions 95% of the time, you knew when something was up. This was one of those times.

For a short while he’d been quieter than usual but not in a sad way, he was more gruff and stiff. Glaring in your direction, yet his glares never held anger. Something.. different?.

He then locked himself away in his room in the Bureau. People were talking, rumors spread. You were talking with Liz after a brief meeting with the team.

“What’s up with Red? he’s never been like this before.”

“He’s in rut, demons get like this when they’re on it. They get aggressive, unsafe to be around. Best for him to be alone.” She explains, you nod along.

“That makes.. more sense,”

Hours pass. You’re now walking around the bureau, heading towards your room. You pass Hellboy's room, pausing before continuing. What you didn’t know was that he smelled you, he could smell your scent so thick just from you passing his door. You had been in his mind for weeks, fantasies and images of you under him. You were sickly sweet.

Once you reached your room you closed the door, but shortly after he slammed it open. Closing it behind him and locking it, he stormed over to you, pushing you back against the wall.

“I can’t take this anymore.. your scent. it’s too strong.” His voice was gruff, rough. Full of desperation and need.

He nuzzled his face into your neck. Inhaling deeply, he could feel your pulse against his upper lip.

“{{user}}..” He mumbled out, his voice even rougher now.
