Derek chewed on his lower lip for a few moments before asking "Are you sure you want to do that?"

Stiles crinkled his nose and smiled. "Yeah, they need to know and maybe Peter can suggest a different pediatrician for Lily. As strange as it sounds, I think Lily needs the pack as much as the pack needs her. Plus I really need to see their faces when we introduce our daughter to them. It should be a true Kodak moment."

Derek couldn't help but snort at the idea. "Scott is going to have a fit if you call Lily our daughter."

"Then Scott can get happy in the same pants he got pissed in because it's true. We are a couple and Lily is our daughter. How much do you want to bet that he thinks I actually gave birth to her? Oh, wait - is male pregnancy a thing I'm going to have to worry about when we have sex?" Stiles asked distractedly.

Derek had a sudden 'falling' sensation at Stiles question. He had let his mind briefly supply him with an image of a pregnant Stiles holding an older Lily's hand. "No, I don't think so. My uncle Gary never got pregnant by his mate. You can ask Deaton or Peter if you want to though."

"No I'd rather not," Stiles said with a chuckle doing his best to forget all about the doctor's office visit. He was nervous about the packs reaction to Lily, but that was another thing he needed to let go. They would accept her or not. Either way it wouldn't influence his love for his baby girl.

A comforting silence fell in the car as Lily suckled on her bottle and each man was lost in his own world. After twenty minutes though, Stiles had Derek pull over so he could burp Lily. There was no way he would let her tummy get upset when pulling over onto the shoulder would be quicker.

"Should I tell the pack about Lily?" Derek asked as he pulled out his cell phone getting ready to send out word for a pack meeting.

"No, my dad will be at work, so just ask them to show up at the house for an important meeting," Stiles said with a grin.

"You realize that they are going to think it's an emergency, don't you?" he asked with his eye starting to twitch.

"Okay, then text them when we get home. I would say for a surprise, but you wolves are hard to surprise."

"You sure as hell surprised me," Derek replied smiling at the duo.

"It was a good surprise though, right?" Stiles said with an answering smile.

"Yeah, she was a good surprise. So, we text them when we get home and surprise the pack. You sure you want me to include Peter?" Derek asked nervously.

"Yes, even though he's a creep, he's family, and he's pack. Lily needs both and she has enough cute power in her to knock him on his undead ass if she needs to," Stiles responded with a mischievous smile.

Derek grunted in agreement as he put away his phone never taking his eyes off of Stiles and Lily as Stiles burped and then quickly changed her wet diaper before strapping her back into the car seat. He did it all like a Ninja Momma (not that Derek would ever tell Stiles that.) In less than ten minutes they are back on the road headed home.

Stiles quietly played with Lily in the back seat until the motion of the car and Stiles soft voice lulled her into a peaceful sleep. The young man could not stop smiling on the way home. It was hard to believe that just a week ago he would have laughed at the thought of taking care of a baby and would have said the person needed committed if they said he would be raising a wolf cub with Derek Hale.

Yet, here he was with his little girl in the backseat of his mother's old car, happy; with Derek driving and giving a small happy grin himself. Derek's contentment seemed to just roll off of him in waves. They weren't the perfect 'couple', but they were trying and that is all any parent could really do.

The rest of the ride home was silent and content, with both actually looking forward to seeing the pack's reaction. They were all a wild card for him. Including Scott, especially Scott. Stiles had told Melissa the truth when he said that he couldn't cut Scott out of his life, but he also couldn't and wouldn't cut Lily out of his life.

No matter the other boy's reaction, or even the pack's reaction; Stiles would finish high school, look into college, and be fine because he and Lily already had a wonderful support group.

When they made it home, they silently filed out and settled the sleeping Lily in her crib as they got ready for the packs 'invasion'. "So, how long has it been since anyone in the pack has seen you?" Stiles asked as he checked on the food and drink levels in the house.

"About a week," Derek said with a slight shrug of his shoulders.

Stiles couldn't help but to snort at hearing this. "I'm surprised that they haven't stormed the house yet."

"I told them to back off for a while that you were helping me figure some things out."

"In other words they thought you were busy fucking my brains out. Which would explain why Scott hasn't even texted me since I made it back. You realize that once I'm old enough and the pack is all settled, you owe me some serious sex time. Oh, and the first one in the pack to call me 'Mary' will get flayed alive," Stiles warned.

Derek's brow creased in confusion as he picked up the living room floor. Hey, three men taking care of a baby wasn't exactly a recipe for cleanliness, though Stiles liked to think that he had done a near superlative job of it. "Why would anyone call you 'Mary'?"

"Because I'm Lily's Mommy," Stiles said softly.

"Yeah, I still don't see why they would call you Mary."

"Because I am a virgin and a mother," Stiles hissed.

Derek stood there blinking as the information just tried to settle in his brain. "I promise to growl at anyone who makes the joke, including Peter."

Stiles could only roll his eyes and mutter "My hero," as he continued to clean the house. "Hey, are there any snacks or anything we need for this shindig?"

"It's not a shindig, it's an announcement and I'll tell them to BYOS or something. We'll be okay Stiles. We don't have to impress them, they're our pack," Derek said calmly as he walked to the younger man.

"You don't have to get them to accept you. I do and they have to accept Lily. What are we going to do if they don't like Lily?" Stiles moaned as he grabbed the front of Derek's shirt and held on for dear life.

Derek wrapped his arms around the slightly smaller man and rubbed his back before he finally said, "If they reject her; I will bite them and tell them to submit or get."

"Don't say things like that; I might start to believe you. Now let me go so I can run upstairs and get Lily ready while you text the goobers to come on over. Oh, should I be down here or upstairs when they get here?" Stiles asked as he patted Derek's broad chest.

"You said you wanted to surprise them and I don't want to have to repeat the story more than once, so I think upstairs would be for the best," Derek said as he released Stiles.

"Okay, how long do I have to get her ready?" Stiles asked as he went to grab a fresh bottle and the water, he put both in the diaper bag, just in case Lily for hungry while he was getting her ready.

"Fifteen minutes I think. That should be enough time for everyone to get here and I'll call you down when I think everyone is ready to meet Lily," Derek said with an outward calm. Though Stiles could tell that the man was more nervous than he was letting on. The 'Alpha' face had stopped confusing Stiles a long time ago.

"I can't promise she'll be awake, but we'll be ready. Thank you Derek," Stiles said as he slung the bag over his shoulder and picked up the sleeping baby from the couch. He walked over to his Alpha and kissed him on the cheek before dashing up the stairs to get ready for Lily's debut.

He decided to go for broke and use the black onesie Deaton had brought over yesterday. Derek hadn't seen it yet and Stiles was almost positive that Derek would want to roll his eyes, but wouldn't because the pack would be there.

Once Lily was dressed he toted her to his room and laid her on his bed so that he could get ready as well. True this was about Lily, but he was also to be introduced as a new pack member... so he should at least try to dress for the occasion.

After he put on a blue button up shirt and a nice pair of jeans he sat down beside Lily and waited for Derek to call him down. He had no idea why he was nervous. Everyone in the pack knew him and considered him 'pack' already, but what if it was a joke? Or just them saying it to placate the human?

He stopped breathing when he heard the first knock on the door. Peter and no one else. He would have expected Scott and Isaac first, seeing as Scott lived so close to Stiles. Though perhaps they were working.

A short while later another knock. Sharper and somehow more annoying than the first. Erica and Boyd, it had to be them. He couldn't hear Boyd, but he could hear Erica asking about the emergency and where she was Boyd was sure to be. After their kidnapping incident they never strayed far from one another. Stiles hoped that their fear would turn into genuine love, they both deserved it.

Then came an odd sounding joke and the jingle of keys, which could only signal the arrival of Scott and Isaac. Isaac's knock was a timid soft knock and only Scott had the knowledge of where the Stilinski family kept their spare key and had the balls to use it.

He wished he had thought to invite Lydia and maybe Danny as well, it would have been nice having other humans in the house with him.

Stiles slipped out of his room, Lily bundled in his arms, and listened for his cue from Derek.

"Why haven't we seen you in the past few days? Where's Stiles? Is he back from vacation or are we breaking and entering in their absence - again?" Erica asked with a laugh.

"Let's just get down to business," Derek said with a sigh knowing that he would have to explain that to Stiles later, hopefully when they were alone.

"Business it is then," Peter said with a clap of his hands. "What mortal peril is on the horizon dear nephew?"

"No peril, not yet. We, um we have a new pack member. I just felt you should meet," Derek stammered and Stiles took that as his cue to come down the stain.

"Wait," Scott growled. "Stiles is our newest pack member? You bit him? You son of a bitch."

"I thought Stiles was our token human? Did he get hurt or something?" Boyd asked quietly.

"Shut up all of you!" Stiles said as loud as he dared.

"A baby," Peter whispered with a hitch to his voice.

"Yes," Stiles said with a grin. "Everyone I would like to introduce you to Lillian Talia Stilinski-Hale," Stiles said clearly as he tilted the slumbering babe to the assembled pack.

"You fucking got Stiles pregnant with your mutant werewolf sperm?" Scott yelled as he launched at the alpha.

It was a shock all around when Peter grabbed Scott by the scruff of his neck and pinned him to the floor.

"There is an infant in the room. A werewolf infant who does not need to be startled in the arms of our human pack member. You will lower your voice and calm yourself; because if you wake that infant up I will bite you and if you happen to hurt her; I will kill you," Peter said coldly and calmly.

"Scott, Derek and I just started going out and in case you forgot, I'm a boy. I found Lily in pup form in the Rockies. It doesn't make her any less mine or Derek's daughter," Stiles said while stroking his daughter's head. "Get over it dude. Your mom already accepted the role of Grandmother and Lily is as cute as a button."

Scott made a sound of frustration, "You're not even finished with high school yet you idiot. How are you going to have a baby and finish school? You're young and I honestly don't think you're ready to be a father to anyone, let alone a werewolf."

Stiles pursed his lips and shook all over. He had heard this lecture before. Hell, he had even given it to himself. What the fuck was Scott thinking going on like that?

"Idiot," Stiles heard Peter growl with the accompanying sound of flesh striking flesh. Stiles saw the older man approaching him slowly when he opened his eyes. "May I hold her?" he asked softly with his hands twitching at his chest as he restrained himself from taking Lily from Stiles' trembling form.

Rather than looking to Derek for guidance; Stiles looked deep into Peter's eyes. Searching for any trace of malevolence that might be lurking within the older man. Finally Stiles nodded and carefully handed Peter Lily.

Peter carefully pulled back Lily's blanket and stared in awed wonder at the child in his arms. "She's beautiful," he whispered as he carefully traced her delicate features.

"Thank you," Stiles said with a genuine smile.

"So she's yours then. Who's the mom?" Boyd asked from his perch on the couch.

Stiles chuckled nervously knowing his answer was not going to make Scott happy at all. "I'm the mom and Derek is 'Daddy'."

"So, you did knock Stiles up! How could you fucking do this to him? How could you ruin his life Derek?" Scott ranted.

"Scott, continue to yell around my daughter and I will ask Derek to rip your throat out with his teeth. You saw me before I left with my Dad. Not for long but I did manage to spend a whole two minutes with you before Allison called and distracted you. Did I look pregnant then? No, I did not. Know why? Because Derek did NOT knock me up. He CHOSE to help me and I CHOSE to accept his generous offer," Stiles growled watching as Peter gathered Lily closer to his chest as he frowned at the Beta he had bitten all those years ago.

"You're never around anymore Stiles. You're always with that dick and now you're telling me you just happen to have a kid and Derek is helping out of the goodness of his heart? What's in it for him? You going to bend over and let him fuck you whenever he wants some tail?" Scott ground out.

No one could, or honestly would, have stopped Stiles from punching his best friend in the face making him fall flat on his ass. "Lily is my daughter, Derek is helping. Deaton asked him to accept us in this pack and I asked Derek to date me. You know how I feel about him. I told you this last year. YOU ditched me for Isaac and Allison a long time ago Scott, Derek was a friend and helped make my time less lonely. He's a good man and I want him to be with me and I desperately want to be with him. Get your head out of your ass Scott, this is not a meeting to ask you if you approve, this is a meeting telling you how it is. I don't want to lose my brother man, don't ask me to choose between you and my child; you will not be happy with the answer."

"You're saying you would choose a baby over me?" Scott said from his position on the floor.

"Dude, this isn't a contest. Tell me something, if Allison had a baby and it wasn't your baby, but she wanted you to help raise it, would you?" Stiles asked seriously.

"Of course I would."

Stiles nodded and then asked; "Even if I didn't approve? What if I made you choose between Allison's child and me. Which would you choose?"

"My child." Scott said sullenly.

"Allison's child, she only asked for your help. She didn't ask you to co-parent. So you could be seen as Uncle Scott." Stiles states with a shrug.

"Where are you going with this?" Scott asked as he carefully stood up.

Stiles sighed deeply and winced at what he was about to say. "For lack of a better comparison, Derek is my Allison and I did ask him to be the Daddy."

Scott hung his head and nodded as he finally understood. "Sorry," he muttered.

"Don't be sorry. Just tell me you'll be here for me and that you're still my brother. Lily needs an Uncle besides Peter," Stiles said seriously while he examined his poor knuckles.

"I'll be her uncle in name and stuff. Just don't ask me to babysit or hold her."

"Yeah, because we want the man who hates her Daddy and possibly her to hold our daughter," Derek muttered as he moved to stand beside his uncle.

Scott just shrugged and silently went back to his perch beside Isaac. "Any other problems?" Stiles asked the remaining three pack members.

"I'm not going to watch her either," Erica said from beside Boyd. "I'll play with her, might feed her when she gets older, and teach her that boys have cooties, but no baby sitting and no changing dirty diapers."

"Not a problem," Stiles said with a small chuckle. "Boyd, your opinion?"

Boyd gave a true and open smile. "I like babies. If you ever need a sitter I would be happy to take her. I even know how to change diapers. My Sister had a baby last year."

"You, my man, are awesome. Derek and I may take you up on that when we make it official." Stiles finally turned to the frowning Isaac and smiled slyly. "What about you Isaac? You up for having a little sister around?"

Isaac looked up at Stiles in shock before turning to his alpha and whining; "You told him!"

Derek crossed his arms and rolled his eyes. "He deserved to know and it looks like he actually accepts it, so what's the problem? Is having a sister the problem?"

"No! Lily is cute, I don't - they're," Isaac winced looking at his pack mates.

"I don't think that they are going to pick on you for wanting a Mommy and Daddy. Just, don't call me Mommy at school that is only for 'pack' and 'us' times only. You guys aren't going to pick on him are you?" Stiles asked seriously.

"It's cute, but is it okay if Boyd and I don't call you and Derek Mommy and Daddy?" Erica asked as she ruffled Isaac hair.

"That's fine, want to be Aunt and Uncle instead?" Derek asked with a mischievous grin.

Boyd grinned widely and Erica also grinned at the idea. "I think we can live with that," Boyd answered for them both.

"Peter? Are you willing to be Lily's crazy uncle?" Stiles asked with a small smile.

"It would be my honor and privilege to be Lily's Uncle. You chose a good man for a mate Derek. Be sure to keep him, if you don't I might just snatch him away," the older man said seriously.

Stiles chuckled and shook his head. Everyone was pushing for him and Derek to be together... and it honestly felt like it would happen sooner rather than later.

"Leave him alone Peter," Derek growled.

"Listen to your Daddy Lily, he's very possessive of your Mommy, isn't he. Was this the only reason for the unexpected pack meeting," Peter asked as he gently rocked Lily.

"We were hoping that you would know of a pediatrician. Dr. Okami kind of fell through," Stiles admitted with a slight wince remembering his earlier snit.

Peter rolled his eyes and looked toward the sky. "Okami is a twit of the highest degree. I would suggest Dr. Tarkington over in Aromas. It's a little closer and she is an old family friend who knows more about werewolves than Okami ever will. Of course, that's because she is a werewolf herself."

"I thought Mom used Okami," Derek said with a frown.

"Talia took Maria to him once. He missed her ear infection. She didn't take that too well, in fact she may have threatened to cut off his balls for incompetence," Peter said with a chuckle.

"Ah, that would explain why they sent a shadow in first. Which neither of us appreciated," Stiles said with a frown.

"Look who is up. Hi Lily, I'm your Uncle Peter. Welcome to the pack sweetheart," Peter cooed as Lily opened her eyes and blinked at him.

Lily frowned at him and looked around. Stiles looked on with wide eyes and knew what was coming. Knew it with every fiber of his being. He scrambled up the stairs and grabbed her bottle just as Lily started to fully bawl – read cry at the top of her very good set of lungs.

Stiles quickly added the water and mixed as he made his way back down the stairs. He quickly handed the bottle to Peter and waited to see what would happen next. Which was Lily refusing the bottle and crying harder.

"Okay, let's see if Mommy can't settle you down," Stiles said calmly as he took his daughter from a sad looking Peter. "There, there sweetheart, Mommy has you now. No one will hurt you."

"I would never hurt her," Peter said with wide eyes.

"I never said you would. Didn't you ever say things like that when you were holding other babies?" Stiles asked as he carefully bounced Lily while pacing the room.

Peter narrowed his eyes at the young man. "That is not the point I was attempting to make and I only said that to soothe the baby."

Stiles grinned excitedly at the older man and simply said, "Exactly." As Lily started to calm down.

"Oh," Peter said as he deflated on himself. Stiles was sure that Peter had taken it all wrong.

"You hungry now sweet baby girl? Or do you want to look around at your pack? Like Daddy, they look tougher than they are. Well except for your big brother Isaac. He's as cute as a button as are you," Stiles said while smiling at his little girl.

"I am not cute!" Isaac said from the couch. "And I do not recall agreeing to be her big brother. What if I want to be an Uncle or something?"

Stiles just stared at him flatly and said, "If that's your choice." Not letting on how much he had been looking forward to growing his family just a touch more.

"Sorry," Isaac muttered. "I - I do want to be in the family. I just wish we could make it legal."

"Give Derek and I a chance to get our lives settled and then I'll talk to a lawyer about adopting you. We won't even have to go through a great deal to make it official. Does that sound good to you?" Stiles asked as he plucked Lily's bottle out of Peter's hands.

"That sounds great. Thank you - Mommy," Isaac said shyly.

Stiles lit up like a 300 candle Christmas tree when he heard Isaac calling him 'Mommy' for the first time. "Come here and meet your little sister."

Isaac got up and approached the pair in spite of Scott giving him the 'what the fuck' eye. Yeah, they all got the memo that Scott had issues with Stiles life choices and Stiles could honestly say that he didn't give a rat's ass about Scott's opinion at that moment. "Lily, I want you to meet Isaac. He's your big brother, so you have to promise not to run roughshod over him," Stiles said as the younger man approached them.

"Hi Lily," Isaac whispered shyly at the squirming girl in his mommy's arms.

Lily let go of her latch on the bottle, squealed in delight, and waved her arms at the nervous young man. "I think she may want you to pick her up," Stiles said with a small chuckle.

Stiles carefully placed Lily into Isaac's arms, handed him her bottle, and stepped back from his children.

He felt Derek wrap his arms around his waist and leaned back into his boyfriend's arms. Looking around at the pack he felt more at ease than he ever had.

Yes, he was a seventeen-year-old virgin mother of two. Yes, life liked throwing curve balls his way. No, he wouldn't give any of it up; because his life wasn't perfect, but it was good and full of love.
