Hello again readers. It's time for Stiles' first playdate. Question is, who is it with? Well read and find out.

Chapter 5: Puppies and Playdates

Derek was up first the next morning, pulling away from Ennis to go get Stiles ready for that afternoon. When he entered Stiles was sprawled out on his back in his crib, thumb in his mouth and snoring lightly. He smiled and gently lifted him out, getting a happy sigh from him as he laid him down on the changing table.

"Stiles? Time to wake up puppy." He said gently, rubbing Stiles' stomach. Stiles muttered softly, eyes straining against the sunlight filtering in. "Morning pup. Ready for a bath?" Stiles shrugged, still not fully awake and sucking his thumb. Derek chuckled and took him into the bathroom. He sat him on the bathmat while he filled the tub. Once it was full he put Stiles in and started washing him up. After getting him clean he got him dressed for the day in a black onesie with a fire truck on it and some shorts.

He took him downstairs and fed him his morning bottle and some cheerios while he made sausage and toast for himself and Ennis who came downstairs a little while later. He kissed Stiles on the forehead and Derek on the cheek before going to inform their pup of their little surprise for him.

"Morning pup. Daddy and I have a surprise for you today." He said with a smile. Stiles tilted his head a bit at the mention of a surprise, what were his 'parents' up to? While he was doing a good job of keeping in his younger head space, Adult Stiles had gotten curious the second the word surprise was uttered. It was too early for him to be going outside and they knew he wasn't ready for that so what on Earth were they planning?

His day was a whir of watching Derek clean from an over-sized playpen while cartoons played on the TV, Derek childproofing cabinets and hallways and the stairs and talking to someone on the phone. The whole while Ennis had left the house and Stiles was left wondering about the surprise. At around two he got his answer when, after waking up from his nap, he heard Derek open the door to the loft.

"Good timing, he's just waking up from his nap, come on in." Derek said with a small smile. Stiles stood up in the playpen and his heart sank when he saw Scott and Isaac walking into the loft. He started to panic, desperately trying to climb the rails of the playpen or unlatch the door so he could run and hide. The three wolves could hear his panicked scrambling and Derek went to get him. "Stiles? It's okay pup, it's alright." He said, trying to calm him.

"No, no it's not alright. You promised, you promised no one else would know." He said, fear flashing in his eyes and coating his voice. Tears started running down his cheeks. "You promised, you promised." Derek shushed him gently, picking him up and taking him into the other room.

"It's alright Stiles. It's part of the surprise, Scott and Isaac brought you a friend to play with." He said, brushing away his tears and not bothering to punish Stiles for talking back to him because he was understandably freaked out. He and Ennis had promised they would be the only ones who knew but they also knew Stiles wouldn't be able to handle being alone forever. He was going to need a companion to play with regularly.

After waiting for Stiles to calm down he gave him Mikko to hold for comfort and carried him back out into the living room. Stiles buried his face in Derek's neck, cheeks and ears red in embarrassment as he hid away from his best friend and his mate. Scott understood this type of change was sudden for Stiles who was so used to being isolated from the rest of the pack.

"Hey Stiles." He said softly, not trying to spook him or anything. "Isaac and I have someone who wants to play with you." Stiles slowly turned away from Derek's neck, eyes full of distrust and fear at this new intrusion into what was supposed to be his private going on with Derek and Ennis. "It's okay, we know this is kind of weird. It's weird for him too."

"If it makes you feel better, he's just as scared as you are." Derek said. Stiles wondered who they were talking about, now more curious than upset about the situation. "Do you want to meet him?" They waited and after a while Stiles shyly nodded. Scott smiled and Isaac went out into the hall, coming back with a very frightened looking Liam clinging to his arm. Stiles was a bit shocked. Of all people to get roped into this as well, Liam with his hair-trigger temper was never even on his list.

The pup looked absolutely terrified in his Buzz Lightyear tee and jeans as he hid behind Isaac.

"Come on Liam, Stiles won't hurt you." Derek said, putting Stiles down. "Why don't you show Liam your dump truck and blocks? Make him feel more comfortable. Daddy will be right out here talking with uncle Isaac and Uncle Scott, okay?" Stiles nodded and Isaac nudged Liam forward, watching as he shyly followed Stiles into the living room to play. Derek, Scott and Isaac sat down at the kitchen table to talk.

"That went better than I thought it would." Isaac said. "Stiles looked like he was gonna breakdown and safeword." Scott nodded.

"I was worried he would too." He said. "I know this is really weird for him but he doesn't think he's part of the pack. He needs to feel comfortable around us. Same goes for Liam." Derek nodded in agreement.

"I know, it took us a while for him to get used to this idea and his little freak out had me scared." he said. "He's already safeworded once. But he didn't and I'm actually glad he didn't. He needs to get used to the idea of other people being around."

"I hope one of those other people isn't Peter." Scott said. "I already know I don't want him anywhere near Liam. That would only be bad for him. Peter's a psychopath after all."

"I know, that's why I kicked him out before I asked Stiles. Peter loves to nitpick and it would only be bad for Stiles if he was around." he said. "That's why Ennis is out, he's making sure Peter knows where his boundaries are, he might be my uncle but as far as I'm concerned he's no longer part of the pack." Isaac and Scott nodded in agreement. After all the backstabbing Peter had done in the past it was a wonder Derek didn't kick him out of the pack sooner. While they continued to talk in the kitchen, Stiles and Liam sat awkwardly near each other.

Neither of them really knew what to say to each other and given how Liam was dressed Stiles could tell he was in a mentally older head space, which meant he was subsequently older than he was at the moment. Stiles was fiddling with Mikko's ears, stroking the soft fabric for comfort when he heard Liam shuffling around. There was a soft crinkly sound so while his head space was somewhat older he was still either in diapers or in pull-ups, something that gave Stiles a little bit of comfort since he still wasn't used to his own diapers.

He looked over to see Liam digging around in the huge toy chest Ennis had placed down here so Stiles could have toys nearby at all times. He pulled out an airplane and a few blocks. Stiles watched him build the blocks up like an airport and pretend the plane was taking off. He was clearly easier at slipping into a head space when he was faced with an awkward situation than Stiles.

Stiles watched him for a while before crawling over. Liam stopped and looked at him.

"C-can I play?" he asked shyly. Liam nodded.

"Okay." He said. Stiles smiled a little and pulled out his favorite dump truck and helped Liam build an even bigger airport and even a second one on the other side of the room for him to land the plane at. Derek came to check on them and smiled, seeing them playing nicely together. Scott had been worried the two of them wouldn't get along where, as Stiles had mentally put himself between the ages of two and three, Isaac had informed him Liam's head space was at least four and a half. Thankfully though they were getting along.

"They're fine. They're just playing together." He said with a smile as he sat back down at the table. After a few hours, it was time for Scott and Isaac to take Liam home, something that greatly saddened both of the pups as they were having so much fun with each other.

"Don't worry Stiles, Liam can come over tomorrow. Okay?" Scott said, smiling at him. He was actually very happy his best friend was happy with this right now as it had been a long while since Stiles was seriously this happy. He nodded and watched them from the window as they drove off. Stiles sniffled a bit and Derek quickly picked him up.

"It's okay puppy, Liam will come back tomorrow." He said. Had he known Stiles would have gotten so attached that fast he would have had Scott and Isaac bring him over sooner. He fed Stiles his bedtime bottle after his bath and read him a story before putting him down for the night. He was in bed reading when Ennis finally came home.

"Your uncle is persistent." He said gruffly, not at all happy with how his day went. Derek put his book aside and kissed him.

"I know he is, sorry." He said with an apologetic smile. "The baby's in bed so I can make it better if you want." Ennis growled and nipped at his mate's neck.

"You better, you owe me after the fuckery I had to put up with." He said, giving Derek's ass a squeeze. The shorter alpha chuckled and pulled his mate into bed, shutting off the lights.

Well another chapter down. Please note that Liam is currently the only Season 4 character to appear in this. He will be the only one to appear mostly because my sister kept making the joke about Scott being his father after he was bitten so that's why he's here. Anyway, you people didn't think I would forget about Peter did you? I wish I could but Satan in a V-neck is very hard to forget. Plus for all it's cuteness a little drama couldn't hurt this fic now could it?
