A/n: second Macgyver request done! Enjoy peeps. This one is about Mac's little sister who is visiting on her sem break and meets Jack and Riley for the first time. Even though she already knows who they are from Mac and Bozer talking about them and sending the occasional picture of them together. @clonesdserveb3tter
Bozer was in the kitchen making breakfast for everyone in the house. It was early in the morning and none of them had to go into work for once, well they hadn't been called in yet since crime had decided to be kind and take a day off. Instead of being heroes, Bozer finished placing the last pancake on the plate while Mac was fighting a different kind of problem.
Bozer had asked him to look at his bathroom lights, he had tried to find the problem when he woke up but gave up after he couldn't find what was wrong with it. And, since he has Mac as a housemate he thought he could fix his problem with all his geniuses. So, meanwhile, he was preparing the food for all three in the house, Mac was fixing his bathroom light.
You might be wondering who the third person was in the house. That answer would be quite simple. (Y/n), (Y/n) Macgyver, the little sister of his housemate and technically also his sister. Bozer had been by their sides for so long and even took care of her sometimes when Mac went to the Army. Today was her first day staying after a long time, both Mac and Bozer drove to the airport the day before and picked her up. It was already quite late when they all saw each other again, for that reason they immediately hit the hay when they arrived back at their house.
(Y/n) took the next flight over to LA when she was done for the day to spend most of her time with them. So when they arrived they soon found out that she had forgotten a few things to pack. Thankfully they weren't anything they hadn't had in their house.
One thing she had forgotten was her toothbrush and sleep wear. Both were pretty easy to solve. Bozer still had a new toothbrush in his bathroom and Mac lend her some of his clothes.
In the morning, (Y/n) stepped out of Mac's room and towards the kitchen when Bozer placed the pancakes on the kitchen isle. She wore one of Mac's old College T-Shirt and a pair of shorts. The shirt reached her mid-thigh and obscured the sight of her, well her big brothers, basketball shorts.
In comparison to her brother, (Y/n) was slightly smaller than him, at least when it came to clothing size, but that simple worked in her favour when she needed to lend stuff from him that she forgot. Bozer was already used to that. When they were little and had sleep overs, the grandfather of theirs didn't really bother with buying real sleep wear that they would outgrow in a couple of months. He spend the money later when they roughly finished their growth spurt and focused on buying good footwear instead. So (Y/n) always wore big shirts to bed since she was a kid and had no qualm in running around like that.
"Good morning, Boze."
"Good morning, (Y/n)." Bozer hummed as he twirled around in the kitchen and focused on the eggs he cracked into the pan.
"You been up very long I see."
"Yeah, I thought I'd prepare some breakfast for your first night here since… well, since forever. You really need to come over more often." he waved his spatula at her before turning back to the stove.
"Some? This is a feast, Boze." (Y/n) stared at the isle as she took a seat in one of the high chairs.
"That's what I him when I saw it." Mac entered the kitchen area as he wiped his hands on a towel before taking a seat next to his sister. "How did you sleep, sleepy head?"
"Like a baby. These seat in the air plane are hell. But that is the only way to get here faster. I'm not driving all the way here, that takes ages." She sacked down against her chair as she scanned all the different types of dishes.
"Understandable." Mac chuckled and took the plate Bozer was handing him.
"Thanks for the meal, Boze." Both Macgyver's exclaimed and picked their food, shortly after Bozer joined them too after taking his apron off and sat across from them on another high chair they had.
A comfortable air surrounded them as they ate their breakfast and held their conversation. At least until they heard a booming voice fill the space as the door opened. All three turned to the front door. Mac could see the door better than his sister as she sat behind him and had to pear around him to even see their guests.
Jack and Riley walk into the house like they always do, well like Jack always does, Riley would still prefer to knock or something but she got used to the barging in on Mac and Bozer and didn't comment on it anymore.
"Heyo, boys! What is for—." Jack froze with a step into the kitchen, making Riley nearly crash into his back. Avoiding bruising her nose against his back, she manoeuvred around him as she threw him a mix of annoyance and confusion until she scanned the room.
"What's going on Jack. Don't just…" She stops and doesn't only see Mac and Bozer but also a pretty and a little younger girl, that looked extremely similar to their boy genius, in one of the boys t shirts sitting with them at the kitchen island.
"Uuuh morning guys… Wh-"
"Hey, who's that?" Jack cut her off and immediately walked to Bozer and stood next to him as he looked over the girl who was eating with Mac next to her. (Y/n) simply resumed eating, shoving another fork full of pancakes pass her lips as Jack eyed her with distrust as he had never seen her before.
"Oh, yeah. That's (Y/n). She's on her semester break and came over for a visit."
"Okay… I get that but why is she here?" Jack stares at her, one hand slowly going to the back of his waist band as he raised a brow at her.
"Jack sigh that's my younger sister. she's here for a visit." Mac rolls his eyes before stopping his sister, lifting her arm as she nearly got peanut butter on her arm and on his shirt she borrowed.
Swallowing what she was chewing she waved and smiled "Hi, Jack. Nice to meet you Riley." She turned to the woman, that had accepted the change of setting faster than Jack, and returned to her plate, still keeping some of her focus on the new people in the house.
Riley and Jack exchanged a quick glance before the younger one turned back to the new blond head in their group, leaning against the kitchen isle next to Mac.
"Hey. So semester break. What are you studying?"——
The girls went into an easy conversation over him while Jack started to whisper to Bozer, which makes Mac, once again, roll his eyes as he can clearly hear what he was talking about to Bozer.
After a while, (Y/n) was done eating and excused herself. She walked into Mac's room to change her clothes. Jack and Riley followed her figure until it disappeared behind the door. Seconds later Jack broke the silence.
"Since when do you have a sister? And why didn't I know about that?" Jack send Mac and hurt look, if he really meant it or not, no one knows.
"Since when do you have a hot sister?" Riley says as she keeps staring at the door.
Mac's mouth drops even further when he set to answer Jack and stares at Riley in disbelief. "Riley!" he whisper shouts. Riley simply looks over her shoulder and shrugs, taking a piece from the fruit bowl and popping it in her mouth.
"What? It's true." Her words were slightly muffled by the fruit in her mouth as she meets Mac's stare and send him a teasing smirk. Leaning in closer she whispers "Jealous?" Meanwhile, Jack and Bozer were distracted as Jack started eating too and Bozer sat disgusted as Jack talked his ear off with a mouth full of food.
______________
Jack and Riley stayed until it was dark out, all five of them on the balcony and talked around the campfire. Riley and (Y/n) hit it off pretty well and leaned in further into each other as they talked and whispered. The boys could hear muffled laughter as they threw glances at them.
All of them had an amazing time and lead the two out the door. Well, Bozer had an amazing time until he watched flabbergasted at the two girls. More specifically at the phone Riley was holding and typing on.
"Hold Hold on! You giving your number??"
Riley looked up and gave him a confused look "Yeah…"
"Your whole number?!"
"Yes, Bozer."
"Whaaaaaaa! I had to earn each number and little Mac gets it immediately?!"
Riley simply smirked before handing the phone back and winked. Jack and Riley left in his car and the three waited for them to drive away.
(Y/n) stared at her phone when the car drove away and a slow smile spread across her face, biting her inner, bottom lip as a slight blush flushed her ears.
