"This must be it."
After making sure you have the right place, you step inside of the apartment building and proceed towards your big sister's ground-floor apartment unit at the end of the hallway. Thoughts about how your big sister, Erika, could have changed over the years fill your mind as you walk to the door of her unit. Stopping just before the door to her unit, you take a deep breath and knock on the door. Moments later, the door swings open slightly, and you see Erika peeking out.
"Heeeey!" she says with glee, opening the door fully. "${Your name?}! My lil' bro! Long time no see!"
You're in awe of the sight before you. The frail-looking and nerdy girl that you knew is gone, she's now a tanned woman with a nicely toned body who looks like she hits the gym often. Plus, she still towers over you by a few centimeters. Her body glistens with sweat all over, her abs are tight and defined, her arm and leg muscles are toned well, not too bulky. The tight sports bra that she wears accentuates her large bust, which you remember poking fun at when you were younger but now gaze at with admiration. Not to mention her tan lines!
"Uhm, hi... sis..." you meekly return her greeting.
"Come in, come in!" she says, clearly happy to see you. "Don't mind the mess. I was in the middle of exercise."
Stepping into her apartment, you take a look around. Her living room, or whatever room you're in is haphazardly decorated with various exercise equipment—mats, weights, yoga balls, and other stuff. Posters of various athletes are plastered all over her walls.
Erika giggles from behind, prompting you to look back at her.
"Alright, lil' bro!" she exclaims. "You're in my apartment, so it's my rules!"
"Yeah, yeah... I get it," you reply in a bored tone.
"That means, from now on... you'll be working out with me!" she says gleefully, patting you on the back. "Come on, you might end up a better person like me!"
"Uh, let me unpack my stuff first," you say. "I just arrived here."
