Mating season can be hard enough for a demon as it is, but imagine having to stay for a week at your best friend's house. For Dark that is a worst nightmare, he's already dreaded mating season but this just make it 10x worse. The worst part about it is Mark is a pretty handsome guy, and to have a super horny demon with a sexy guy like Mark, things might not go so well... Warnings: Smut and possible rape.
