What have i done...?

It was a full moon but it was different then any other full moon; more powerful. They say some moons carried a blood lust that only happened once a year. However Stiles Stilinsky didn't know that tonight was going to be different from any other night when he went to visit his boy friend Derek Hale. They had been kinda, sorta dating for about two weeks.

Derek hated this time of the year, he normally could control himself, but once a year the monster had control. Derek could hear Stiles coming before he could even see him. His heart raced knowing he wouldn't be able to control himself. Panic took over his thoughts, 'God no...no..no he can't be here.' Derek thought. He could only think of how wrong everything could turn out if he was to let Stiles into his home; how he might hurt him. Walking to the door slowly he braces himself, let's his emotion of worry leave his face as he opens the door before Stiles even knocks. “You have to leave,” he says harshly.

He watches as Stiles face falls, pain written across it as he meets Derek's eyes. “You have to leave...Now,” Derek repeats. He knows he's hurting him, but Derek knew Stiles would never leave unless that happened.

“Derek...what... no,” Stiles starts angrily. “I came here to spend time with my boyfriend and that's what I’m going to do.” Stiles says as he wonders if he should go cause he has a bad feeling. Derek would never be this rude without a reason.

Derek stares into wide chocolate brown eyes, he hates that he has to be rude with Stiles, but it's all about protecting him, even if its from himself. “Stiles please, just listen to me... I need you to go.” he says sounding a little defeated because he knows deep down Stiles isn't going to go. He wonders for just a moment why the teen has such faith in him. It breaks his heart, that he can't just explain why he needs him to go, why he needs him to run away from the beast that's inside him.

Stiles can only stand there looking confused by the tone Derek uses. He can't help but feel like he's missing something as brown eyes meet greyish green. “I'm not going.”

Derek nods and steps a side as he lets Stiles in to the house before closing the door. It's much later after Derek and Stiles have talked about why Derek needs him to go. Derek goes into an explanation about the full moon tonight, about the blood lust, the frenzy of control hes going to lose and how it's going to feel. Stiles can only listen with wide eyes and racing heart, but deep down Stiles knows Derek wouldn't kill him; that's how much faith he has in the wolf. So Stiles explains he's going to stay with him tonight, that there going to ride out the full moon together.

It's around ten when the full moon starts to effect over Derek, and he shifts. Stiles is excited until his excitement turns into ice cold fear as he realizes how true Derek's words were. He stares into hungry looking eyes, they scream for him to run but he can't he stays put. Stiles watches as Derek cocks his head to the side, then he lunges for him! Stiles is surprised he jumps to the side and barley misses the clawed hand Derek swings at him.

Realizing that he might actually die tonight and that the man he's destined to be with is gunna be the one to kill him! Stiles runs for his life out of the house and towards his jeep when he feels a sharp pain in his leg. He couldn't escape Derek, he's a werewolf for gods sake. Stiles can feel the blood leaving his leg where Derek clawed at him. Determined to get away from Derek, Stiles grunts though the pain he feels throbbing through his leg and runs towards his jeep once more. He makes it to his jeep only to hear nothing; Derek wasn't chasing him any more. Just as the thought passed a loud BANG is heard landing on top of his jeep.

Stiles screams bloody murder, then he goes to grab the shotgun he keeps under his seat. It's loaded with regular bullets of course, but he has wolfs bane in the glove compartment. Cocking the shot gun, he fires straight up into his roof. “Down boy, nice doggy.” he says. The sarcastic tone is only met with an angry growl as he hit Derek. Cocking the shotgun once more he fires again, but the wolf has already jumped off the jeep only to land beside it and rip the door off it's hinges. Stiles screams again and shoots Derek this time in the chest. For a split second he worried he might have got his heart, but then the wound heals almost immediately

Derek goes to grab Stiles, but not before stiles grabs a wolfs bane bullet from the glove compartment and loads it into the shotgun and shoots Derek in the leg. He doesn't want the wolfs bane to enter to close to the heart cause Stiles has a plan.

Derek clutches Stiles to him, he can feel Stiles arm break before the scream even leaves the his lips. Then Derek lets go of Stiles as the pain from the wolfs bane gets worse as it moves through his system. Stiles turns to run but derek isn't done with him, he grabs stiles's hip claws digging in! Stiles screams in agony its the third scream Stiles has done that tonight, but he knows the wolfs bane is going to reach Dereks abdominal area soon and waits for him to fall to the ground. While Derek's writhing on the ground in pain stiles considers healing him but decides to wait a few whats a lil more pain for the big bad wolf. Then a few minutes pass and stiles notices that the poison is to close to his heart he doesnt wanna kill derek just hurt him, so stiles grabs another bullet from the glove compartment. He grabs a pair of pliers and pries the bullet apart, he dumps it on the hood and lights it on fire then he smears it in the bullet wound on Derek's leg, this makes Derek howl in agony. While Derek is writhing on the ground in pain stiles limps to the house and passes out a few feet inside the door from the pain and blood loss.
