Okay so I have done this before with someone who played a werewolf and they disappeared so it was never continued but they played the male perfectly! They played as a werewolf, but it can be done as a vampire as well. Like I said, my vampires are more of the Vampire Dairies vampires that are normal temperature as human, look like humans beside the golden eyes or red if angered or hungry for blood. My werewolves are pretty much like twilight werewolves just not as big as the wolves in twilight were, what I look for in a werewolf is when they are in wolf form that they are slightly bigger than natural wolves. What I also noticed when I role played with that person was the fact that they had their character kind of be a player and be friends with benefits with a few girls until he meets my character. Then he throws an end to all that and only wants her and no one else, not only does he want anyone else - but no one else can have her. It's also added drama if someone crosses the line and can't accept 'no' as the answer so he has to sort of put them in their place and defend what is his. Character A is my girl and Character B is your guy whether he be werewolf or vampire. All I ask for this to make sense is that he be the alpha of the pack or the clan leader, only about two or three years older than she is.
So my idea is to have Character A go out on her twenty-first birthday, her friends are all too busy so she just decides to go out alone thinking nothing bad would happen. Well, when a group of men takes quite an interest in her and a few other girls - the group begins to buy the women drinks, slowly pumping them full of date rape drugs until sooner or later they pass out. Well, to make sure they stay out for the long trip - they inject the women with sedatives. This men are members of Character B's pack or clan, it is their job to bring in a steady flow of women so the members of Character B's pack or clan have mates. Some members of Character B's pack or clan have multiple mates and divide time up amongst their women evenly as possible, though some always play favorites and loan out the other women to younger members for the younger members to learn how to have sex - using the women as practice while the women's man watches and instructs the younger member. The trip takes the women all the way across the country to the town the pack or clan calls home, of course other humans live there as well. Character A doesn't remember much after she wakes up, thinking she probably just blacked out from drinking so much. But instead she finds herself locked inside a cage, almost like what dogs are placed in at animal shelters. The door at the front has a lock on it that requires a key and there is a tag on the front that has all her information on it from that fact of her age, weight, height, hair color, eye color, piercings, tattoos, where she lived, her birth date, her blood type, if she smokes, if she does drugs, if she drinks, if she has children or has ever been pregnant, not to mention how many men she had slept with.
Character A is trying to figure out how they know all this stuff before she hears a door open before it is allowed to swing closed, creating a loud bang to echo throughout the building. The building isn't in the nicest shape, it reeked, it was cold, and the floor was wet, even holding puddles in certain places. Some of the women aren't in the best shape either, even Character A is covered in scratches, cuts, and bruises, along with a few minor gashes. As the voices begin to grow closer, women move to the back of their cages toward the wall. Character A is more focused on what the hell is going on and met with a flashlight shining on her, its the same male voice as before when the door opened and she can make out a second man standing next to him. The man standing next to him is no other than Character B. Character B is given the first chance to pick any of the women he wants, he has already picked a few but when he lays eyes on Character A - he wants nothing to do with the other women. He has the previous women put back into cages for his pack or clan members to choose from, explaining to the man with the flashlight that he only wants one women and Character A is it. Character A is removed from the kennel she is in and instantly taken by the arm by Character B, Character A is terrified - fearing what was going to happen whether she left here with this man or stayed in that kennel. Character B has finally found his mate, determined not to allow any other of his pack or clan members to lay a finger on her or even think about doing so.
Their relationship starts out just being about him needing a mate and her just being exactly what he was looking for, their relationship grows as Character B begins to allow a softer side of himself to be shown only to Character A when they are in private. Character B begins becoming more affectionate to Character A by beginning to buy her gifts ranging from jewelry to clothing, Character B even begin to plan out a proposal so that Character A would not feel so much as though she was his property but more as his mate and wife. Character B was never extremely rough with Character A, making sure that if he were to bite her, spank her, or pin her against something that he never actually hurt her but gave her pleasure. Character B allowed Character A to sleep with him, cuddling up against him if she pleased from day 1. Character B also likes to show his girl off and make his pack or clan a bit jealous of him, especially once the affection begins to become less forced and more public. Character B doesn't seem bothered however, enjoying that he can give Character A pda, have her cuddle with him in a chair or one the couch, or have her sit in his lap - he is rather enjoying himself but his BETA male who has no mate seems to mind quite a lot. The BETA male doesn't seem to like the fact that Character A has started to enjoy her relationship with Character B, in fact it's become a natural relationship even if it didn't start out as one. And when Character B proposes to Character A, she has a surprise of his own for him.
