Demons within Me: (The Incubus Slave) Book 1
Tore leeched to different female mortal generations to generations until he found his new Apple of an eye who is Lyca, Felix's lovely wife.
He comes in her dreams every night which made her weak. He always visiting her and it drained her. Everytime he made love with her in her sleeping phase, he never stop until he's not satisfied. I'm not like him though, if my beloved female mortal would tried to engage sex in their dream, I let them do what makes them feel comfortable with, I stopped if I knew that they didn't want to stop the feeling of pleasure.
Like Isabelle, Tore killed her. He visit her also on her dream until I found out. I warned him but he's a stubborn Incubus, he never listened.
