Disclaimer: I don't own Sherlock or anything.
Author's note: I apologise for the late update, I've been very busy recently. But an idea struck me while I was shopping today and I just needed to write it for you. I hope you enjoy this chapter and please review! Thank you!
Sherlock, John and two year old Hamish were out shopping in blue water shopping centre. Sherlock needed new suits and John would like to get some jumpers. Hamish also needed new clothes, little ones grew so quickly.
They had brought the buggy which Hamish presently sat in as they walked to get Sherlock his suits first.
Sherlock was pushing the buggy while John rested one of his hands on one of Sherlock's which was gripping onto the buggy handle. They spoke happily while Hamish kept himself amused with a teddy bear.
They entered the suit shop and Sherlock quickly picked up a few suits that he would try on. John helped him choose some of them and Hamish also 'helped' by pointing at random suits and shouting "this one!" excitedly.
Sherlock entered the dressing room and pulled the curtain across while John sat outside on a armchair just opposite the curtained changing room. John entertained their two year old while he waited for Sherlock to try on the first suit.
Sherlock pulled back the curtain and walked out of the dressing room with the new suit on. He didn't have the blazer on, just the shirt which was neatly tucked into the trousers.
"Ah! You look lovely!" John stood up and came to inspect the suit closer.
Sherlock remained silent for a little bit until John said "Is it comfortable for running and such?"
"I'm sure it will be fine." Sherlock said.
John had his hands on Sherlock's shoulders and he ran them down to the consulting detective's bum and said "They fit you well."
Just as Sherlock was about to say something back a familiar voice broke through their moment.
"And you two once told me that you knew the meaning of decency." Anderson's annoying words made the two turn to him where he stood with Donovan, Lestrade and Dimmock. They all stared in silence at each other for a few moments before Sherlock said "John, you might want to remove your hands from my backside now."
John retracted his hands quickly and blushed.
Sherlock turned to face the group with a glare "Firstly, though it is none of your business, John was just complimenting the fit of this suit. And secondly, what are you doing here?" Sherlock asked.
"Do you stalk us or something?" John asked.
"Dadda!" Hamish leaned up with his arms outstretched to Sherlock.
As Sherlock got Hamish out of the buggy Lestrade began to explain "We're here undercover. You wouldn't be interested. It's a really boring one."
Hamish wrapped his arms around Sherlock's neck and rested his head against his dadda's shoulder.
"Excuse me, sir?" A shop assistant came up to the group.
"Yes?" John answered for Sherlock.
"I'm sorry, sir, but if you're trying on our suits we would appreciate it if you didn't have children within reach." The man said.
"Why?" Sherlock asked.
"Well, because children have sticky fingers, snotty noses, are sometimes sick and things like that. We need the suits to be kept in the best condition at all times before they are sold." The man said.
"Well, I assure you; Hamish hasn't got a cold, hasn't got sticky fingers and will not be sick." Sherlock frowned.
"Sherlock, just give Hamish to me." John said.
"No! This is unreasonable!" Sherlock said.
"Sir, we may have to ask you to leave." The man said, looking slightly put off by the tall man's reaction.
"Sherlock, that's enough now. You don't need to carry Hamish. Give him to me and get back in that changing room and try on the other suits." John said.
Sherlock grumbled but made to pass over Hamish, who was very clingy to Sherlock, but eventually let go and went to John and Sherlock shut the curtains harshly.
Lestrade pulled the other officers back as they were about to leave and said "This is the best cover. We're out with people buying stuff. Hey, John, can we tag along?" Lestrade asked.
"No!" Came Sherlock's voice from behind the curtain.
"Sherlock, they give you the cases, be nice! Sure, Hamish would love you for company, Lestrade." John smiled.
Lestrade, Dimmock, Donovan and Anderson sat on the other chairs, Anderson and Donovan gave a silent protest while Dimmock just got his phone out.
"Hello, Hamish, and what have you been up to today?" Lestrade asked Hamish, who now stood in front of where John sat with his hands on John's knees.
"Shop with Daddy and Dadda! Good!" Hamish answered.
"John!" Sherlock called out.
"Yeah?" John asked.
Sherlock stuck just his head out of the curtains and said "I need your help."
John stood up and gave one of Hamish's hands to Lestrade.
"Dadda!" Hamish protested.
"You stay here with Uncle Lestrade, Hamish. I just have to help dadda with something." John explained and disappeared behind the curtains too.
"Yes, Sherlock?" John asked.
Sherlock stood before John in nothing but his underwear.
"I don't want them here." Sherlock said.
John sighed "Sherlock, I wanted a nice trip out just us three too, but they really do help us out a lot. I mean, Lestrade has babysat twice, he gives you cases, which he doesn't actually have to do. We owe him just this. I know the other three here aren't ideal, but Lestrade's our friend, and we must treat him as such." John said.
"Fine. But don't expect me to be nice to the other three!" Sherlock proclaimed defiantly.
"I wouldn't dream of it. Now, not that I don't love the sight of you in just boxers... and even less... just any sight of you, really-"Dimmock cut John off.
"You do know that curtains aren't sound proof, right?" he called out and they heard the others sniggering.
"Shut up!" Sherlock said and smiled at John.
"Look, I've got to go look after Hamish. He didn't want me to leave." John smiled fondly.
"Dadda! Daddy!" Hamish shouted through and then after a protesting yell from Lestrade Hamish barrelled through the curtains and clung onto Sherlock's shins.
"Come on, Monkey, off of dadda, he needs to try on more suits." John chuckled and tried to get Hamish off of Sherlock.
"Dadda! You oney got pants on!" Hamish stated as John managed to pick Hamish up.
"Good observation, Hamish, but always look further. I'm only wearing underwear, but why?" Sherlock said.
"Not right now, Sherlock. We still have to buy you two suits, Hamish new clothes and me a new jumper." John said and walked out.
Five minutes later Sherlock walked out with a new suit on.
"Better?" he asked John.
"Is it more comfortable than the last one?" John asked, standing while Hamish sat on Lestrade's lap.
"Just as comfortable, really. I like them both. What do you think of it, John?" Sherlock asked.
"Why does it matter what I think?" John asked.
"Because I want to know if me in these suits would turn you on!" Sherlock explained.
"Sherlock!" John protested while the four adults tried to hide their smirks.
"What?" Sherlock asked innocently "Just tell me whether these suits would-"John cut him off.
"Yes, yes, dear, now get back into your own clothes and we can pay!" John rushed and shooed Sherlock back into the changing room with a blush on his face.
"Daddy, you gone all red!" Hamish pointed out.
"Yes, thank you, Hamish." John grumbled and sat down, crossing his arms grumpily.
Hamish giggled.
Soon they were out of the shop with a shopping bag in Hamish's buggy seat while Hamish demanded to walk himself. John held Sherlock's hand while Sherlock's other hand held Hamish's much smaller one. John steered the buggy with one hand.
"Oh, we can get Hamish some new trousers here!" John said and pulled his husband and son into the shop where they were quickly followed by the four police officers.
John picked out a pair of trousers and a t-shirt and Hamish suddenly let go of Sherlock and ran to a jumper which was on a rail at his level.
"This one!" Hamish requested.
"Do you want a jumper?" Sherlock asked.
"Yes!" Hamish smiled and Sherlock got the correct aged jumper and put it in the basket.
"Why did you want the jumper?" Sherlock asked.
"Like daddy! Snugly!" Hamish said seriously.
"Yes, his jumpers are rather soft and make him very comfortable to hug!" Sherlock praised and picked Hamish up, walked over to John and started stroking John's jumper.
"That's a lovely jumper, Hamish." John smiled and put some more clothes into the basket.
By the end of the trip Hamish was sleeping on Sherlock's shoulder and John was carrying about seven bags.
"Well, it was nice spending the day with you." Lestrade smiled kindly, offering to shake John's hand but thinking better than to do so because John didn't have a free hand to shake.
"You too, Greg. Say hello to Mycroft from us." John smiled as they got into the car they borrowed from Mycroft.
"Will do!" Lestrade smiled and went in search for the undercover police car.
"See, that wasn't too bad, was it?" John asked Sherlock.
"Not too bad." Sherlock relented as he strapped their dozing son into his seat.
