All of your friends were currently gathered in Derek Hale's loft. Tension was heavy in the air because while you were friends with everyone here, they most certainly were not friends with each other. In fact, the only reason they were currently gathered together was you.

The alpha pack had arrived in Beacon Hills bringing chaos and terror with them. At first, Deucalion had been single minded in getting Derek to kill his pack. Then he seemed to be trying to get Scott on his side. That all changed when he discovered you. Now, the threat was hand over the girl or we'll kill the pack. None of you had any idea why.

Like Stiles, you were a human. You were useful, smart, and helped them out on several occasions. The fact you had EMT training had come in handy more than once. None of that explained why the alpha of alphas would be interested in you. You put on a brave face, but inside you were terrified. Currently you were on lockdown in Derek's loft.

"Y/N!" Someone shouted your name and your head jerked up to see Stiles crouched in front of you, a frown on his face. "You okay?"

"Sorry, my brain was elsewhere."

He patted your shoulder as he stood. "Understandable. We're going to follow up on a lead. Peter's staying with you."

You nodded once. That was to be expected. Peter declared himself too weak to get involved with the alpha drama. You didn't buy it for a moment. That being said, you were the only one Peter got along with for any length of time and you didn't mind having him for a guard. You watched the pack leave then turned as you heard Peter coming down the stairs.

He gave you a semblance of a smile. "Hello, Y/N."

"Hi, Peter," you said and dropped onto the couch.

He came and sat beside you. "You've really done it this time, huh?"

You glared at him. "How is this my fault? Trust me, I have done absolutely nothing to attract Deucalion's attention."

He simply arched a brow and smirked as if he knew something you didn't. "It must be aggravating to be stuck here while your friends all run off to try to save you," he finally said.

"It must be aggravating to be stuck here babysitting while the real wolves run off to do something actually productive," you shot back.

Peter looked at you in surprise for a moment then laughed loudly. "That's why you're my favorite, Y/N. You don't take any of my shit. You don't get angry, you don't take it personal, you just come back with something."

You chuckled. "Thanks, I guess. I'm honored."

"Oh, you should be. I don't like anyone." He stood and offered his hand. "Let's find something for dinner. I'm starving."

It quickly became apparent to both of you that Derek needed to go to the store as there was almost no food in his kitchen. Finally, you found some cereal in one of the cabinets, but life being what it is, you couldn't reach it. Peter came up behind you, his front pressing against your back as he reached over your head and grabbed the box from the top shelf. Your heart raced and your breath hitched at the contact.

Peter hummed softly and placed his hands on your hips to turn you around. He didn't give you any more space than you'd had before. "I heard that, Y/N," he teased as his gaze darted between your lips and your eyes.

"H-heard what?" Your voice was breathy and you wanted to smack yourself. Peter was never supposed to know that you liked him. That was the absolute last thing that was supposed to happen. There was no way he would return the feeling so you had hoped to keep it a secret until roughly the end of all time.

He ran one finger down the side of your neck and across your collarbone, smiling when your breath hitched again. "That." His gaze locked on yours. "I noticed it last week actually, but thought I was imagining things. Wishing for things I couldn't have."

You leaned forward and pressed your lips to his. He didn't hesitate before kissing you back. You nipped at his bottom lip and he groaned as he pulled you more tightly against his chest. Your arms looped around his neck to help hold the two of you together. Peter's hands moved down your back, stopping to squeeze your ass on the way to your thighs.

He dug his fingers into your thighs and lifted, never once breaking the kiss. You took his signal and jumped, wrapping your legs around his waist. Your tongues danced around each other as he moved you from the kitchen toward the door that went out to the balcony. It was only when he pressed you against the wall outside that he pulled back to look at you.

His eyes moved over your face, searching for something unknown to you. "Are you sure about this, Y/N?"

"Yes." You nodded and leaned forward to capture his lips again, frowning when he leaned back.

He kept one arm under you to help support you and used the other to cup your chin in his hand. "I need you to listen to me, sweetheart," he said as he looked into your eyes. You nodded again. He sighed and dropped his forehead against yours. "I want this as badly as you do. Maybe more but I need to make sure you understand something. There's no going back from this, Y/N. If we do this you're mine and everything that entails. You already know I'm an asshole, but I'm a possessive asshole."

You took a deep breath and bit your lip before saying, "Do you love me, Peter?"

"I've been in love with you since the moment I first saw you. Why do you think I didn't bite you?" he answered almost without thinking about it. You remembered that night, the night you ran into the alpha and you'd simply stared at each other before he ran off into the woods.

You smiled then leaned forward and kissed him softly. "I love you, too. Why would I want anyone else?"

What you and Peter did that evening was far too frantic to be called making love, but you enjoyed it nonetheless. In fact, you'd barely noticed when he bit your shoulder midway through.

He placed his hand against your cheek and leaned forward to give you a soft kiss. "Next time we'll do this properly."

You giggled and ducked your head as heat flooded your cheeks. Peter laughed. "Still shy after what we just did?" You shrugged and he pushed the collar of your shirt to the side to look at the mark he made. You frowned down at it. "This marks you as mine, Y/N. It's a mating mark. It will look just like this forever," he explained as he ran his fingers tenderly over the bite. He was no longer alpha so you didn't have to worry about turning.

You kissed him again then shivered in the cold. He wrapped an arm around you and tucked you into his side as you walked back into the loft. "I vote for inside next time."

He hummed in agreement then pressed his lips to your ear to speak. "I didn't think you'd want everyone smelling it when they came back." The whisper of his breath against your ear had you shivering for an entirely different reason. He smirked and stepped away from you just as the door opened and everyone poured in.

The next afternoon, you were in your car with your phone pressed to your ear as you listened. You didn't have much to say at the moment. Three of your pack had come home injured the night before. Fortunately it was Derek, Scott and Isaac so they all healed, but that didn't make you feel any better. They'd been hurt because of you.

They had discovered that the alphas lived in the same building as the Argents. If that didn't tell you the universe had a sense of irony, you weren't sure what did. What you were all going to do with the information hadn't been decided yet. You sighed and turned your attention back to the phone.

(Peter's POV)

Once again everyone was piled in Derek's loft. The only reason I was here was to see Y/N, but she seemed to be the only one not present. "Where's Y/N?" I interrupted to ask, not caring what they were talking about.

They all exchanged a look before glancing at me. "She finally left town like we've been begging her to do," Scott said.

I frowned. She hadn't said anything to me about leaving. Did she already regret last night? Damn it. I knew I moved too fast but once she was finally in my arms, my wolf hadn't wanted to hold back. I chewed the inside of my lip as I debated whether to call her or just pack a bag and follow. Derek would tell me where she went. Maybe. If I begged.

"We could use your help if we're going to fight the alphas," Derek said looking at me.

I crossed my arms over my chest. "I already told you it's not going to happen." My only objective right now was to find my mate and protect her. Only her.

"That was before Y/N," Stiles said with a smirk.

I narrowed my eyes at the little shit. Surely she hadn't told them. It would only put her in danger if they knew she was with me. They'd use her against me. "What's that supposed to mean?"

"Come on, Peter," Lydia added. "We've all seen the way you look at her. If you won't do it to help us, do it for her."

Damn it, I'd been too transparent. I couldn't let them make her life miserable because of me. "Why would I do that? Y/N is just another human who needs protection. A weak link in the pack that we'll all suffer for." I cringed even as I said the words, but I needed the others to believe.

There was a long silence as the people around me looked at me with a mixture of anger, amusement and shock.

"You fucking douchebag," Stiles finally said. I arched a brow. "You enormous, idiotic--"

"Stiles, it's fine."

Panic shot through me. That was Y/N's voice, but she wasn't here. I furrowed my brow in confusion.

Derek pointed at the phone laying in the middle of the table, his eyebrows lifted in amusement. She was on speakerphone. Shit.

"Wait, Y/N. You don't understand. It's not like that. You know--"

"Peter, it's okay," she said cutting me off. "I understand."

I frowned. "You do?"

"Of course, if I were you I wouldn't want anyone knowing about me either. I get it. I'm a detriment. A weak link." The sorrow in her voice broke my heart.

"Damn it, Y/N. That's not it at all. Just let me talk to you. Where are you? Let me explain. It's not what you think." I said, frantic. I no longer cared if the others knew about us or not. I had hurt my mate and needed to fix it.

"Peter, it's fine," now she sounded resigned and I didn't like it. Not at all. "It just makes this that much easier."

That got everyone's attention. "It makes what easier, Y/N?" I demanded even as I realized what she was about to do. My stupid, selfless mate. There was only one thing she would do now that she knew where they were. How did I not see it before? Oh, yes, I was thinking with my dick, that's how. "Don't you dare, Y/N. Don't you fucking dare," I yelled.

"I love you, Peter. Goodbye." We all watched the screen as the call ended.

"What just happened?" Isaac asked.

I looked around at the others as my heart broke. "My mate just handed herself over to the alpha of alphas."
