Sorry for the long wait.
"I'm a genius!" Ryuko suddenly sat up in the bed.
"That's debatable." Satsuki muttered as she turned a page of her book.
Ryuko turned to Satsuki, ignoring the comment. "We should turn my room in to a home gym!"
Satsuki paused, eyes flicking to her sister before returning to her book and replying "No."
"What. Why not?" Ryuko crossed her arms indignantly and pouted.
"Because this building already has a gym."
Ryuko frowned. "No it doesn't."
"Yes, it does. I made sure it did when I bought the apartment."
"And you didn't tell me!" Ryuko gasped in mock horror.
"I'm certain I told you about it when we moved in- What are you doing?"
"I'm gonna go check it out." Ryuko had thrown off the blanket and was pulling on her pair of bunny slippers, courtesy of Mako.
"Ryuko it's the middle of the night, get back here."
"But I gotta see it now. Come on. I'm assuming it's on the ground floor, right?" she replied walking out the bedroom door.
Satsuki let out a sigh and set aside her book before getting out of the bed "Ryuko. Wait." She slipped her feet into her own pair of slippers and pulled on a dressing gown.
They took the elevator down to the ground floor, Satsuki got off first and Ryuko followed.
"When do you even come down here?"
"Every morning at 6:30, I would have asked you to join me but you make it a habit not to get out of bed before 9 at the earliest."
"Yeah well you get up at the ass crack of dawn." Ryuko muttered in reply.
"Here we are." Satsuki swiped a key card and opened a door that read Recreational Center.
"Well this is nice. Treadmill, bikes, boxing bags, weights, a variety of other machines that no one knows how to use…" Ryuko said nodding at each machine.
Satsuki leaned against a wall and watched Ryuko walk around the room. "Can we go back now?"
"And a Sauna!" Ryuko gasped.
"There's also an indoor swimming pool, seriously Ryuko, how did you not notice? We've been here over four months now…"
"ehh I'm not particularly keen on swimming." She replied indifferently.
Satsuki raised an eyebrow at this before asking "Ryuko, you do know how to swim right?"
"Hmm? Oh yeah I can swim fine, it's just once you've had to swim with your body chopped in half it kinda loses its appeal."
Satsuki gave her a puzzled look "What- oh. Oh! Ryuko I'd forgotten about that. I'm sorry."
"Nah it's no big deal that was ages ago." Ryuko waved her hand offhandedly before turning around and exiting the gym.
"Where are you going now?" Satsuki asks her.
"Bed, it's pretty late you know. I want to get up early and come down with you in the morning." Ryuko replied as they got into the elevator.
"Oh, okay. I'd like that." Satsuki replied with a smile.
The next morning Ryuko was awake and ready to go at 6:30. Unfortunately Satsuki wasn't. She was instead sprawled out across the large bed, asleep.
"Satsuki. Oi, Neechan, get up." Ryuko knelt next to the bed and stared at Satsuki's face waiting for a response. Not getting one she instead resorted to poking her sides. "C'mon Satsuki. I got up at the ass crack of dawn for this."
Satsuki's eyes opened a crack, after a moment they focused on Ryuko. "It's Saturday. Go back to sleep." With that she rolled over wrapping the blankets around herself. "Weekends I sleep in."
Ryuko huffed "And you couldn't tell me this last night!"
"Thought you knew." was Satsuki's muffled reply.
"Ughh. Fine." Ryuko jumped into the bed and sprawled herself over the blanket burrito that contained her sister.
Some hours later found the two sisters awake and in the gym warming up with stretches.
Ryuko tried not to openly stare at Satsuki as she warmed up. She was wearing a tank top and running shorts, both highly distracting to Ryuko, especially when the shirt rode up to reveal the slight definition of Satsuki's abs.
Ryuko was pulled from her momentary distraction when Satsuki started talking to her.
"Do you want to do what I usually do or do your own thing?"
"Uhh I was thinking I'd run a bit then hit the weights."
"Alright." Satsuki nodded and walked over to the treadmills.
They both started at a gentle jog, 10 minutes in and they were running full on, Ryuko only just managing to keep up. She hadn't realised how out of shape she'd gotten the last few months, no longer having to fight any one every other day.
Soon enough Satsuki started to slow down before coming to a complete stop. She hopped off the treadmill and started on the rowing machine.
Ryuko, still on her own treadmill, couldn't help but stare at Satsuki. Watching as the muscles in her arms and legs moved with each pull, glistened with a light sheen of sweat. After a few minutes Ryuko had to stop for fear of accidentally flying off the machine because of the distraction. Instead she had a large drink of her water and moved on to the weights.
After another 5 minutes Satsuki moved to the boxing bag delivering a variety of kicks and punches. She paused, drank some water and moved over to the matted area where she stripped off her shirt revealing a sports bra underneath. She then started doing sit-ups, which would be Ryuko's undoing.
While watching Satsuki's abs contract and relax, Ryuko's mind went blank. If she had been paying more attention she would have seen the older girls' sly smirk, fully aware of Ryuko gaping at her.
Ryuko let out an almost inaudible moan, she licked her lips, dropped the dumbbells she had long since forgotten about and stood up. She walked over to Satsuki, who stopped and peered up at her.
Ryuko raised a hand towards her sister, "Lets head back." Her voice come out lower than usual, almost guttural.
Satsuki reached up and grasped the offered hand. She stood, a moment passed and Ryuko still held her hand firmly. Satsuki could see Ryuko's pupils dilated, could feel her heart beating faster. "Grab your stuff then."
