Ryoboner

"98...99...100." Feeling your muscles start to tense up, you slowly relaxed as you straightened your back out onto the floor. Catching your breath, you laid there, eyes closed, as you felt sweat pour down your body. With your final set of situps done for the day, you stood up and grabbed your nearby towel, wiping yourself off so that you wouldn't track more sweat throughout the house.

You'd started a fairly rigorous exercise routine within the last week: 300 sitsups, 400 pushups, a 3 kilometer jog, 100 squats, and various stretches every day. You'd created the routine after Ryoubi completely humiliated you when you were both moving furniture into your new home, effortlessly moving your fairly bulky desks and dressers and even your refrigerator while you struggled with most of everything else. She'd used her performance as a way to satisfy her sadism, taunting you about how you were weaker than 'such a skinny and frail girl' and generally just rubbing it in. While such a verbal tirade against you would usually turn you on and lead to a rough little tumble in bed or on the couch, this time it instead shattered your pride as you silently continued to carry furniture inside, determined to become stronger. To this end, you devised your exercise routine and have followed it every day so far.

Finished toweling off, you walked through your house towards the restroom, ready to shower and take on the rest of the day. On your way there, though, you passed through the kitchen for a drink of water. As you entered, Ryoubi suddenly appeared behind you, scowling at you.
"Hmph. Still trying to make yourself stronger, you pathetic little dog? Give it up, you'll always be weaker than me..." Ryoubi's mood had been pretty sour, to say the least, for the past few days, likely due to how much time you'd been spending working out. She probably also thought that you were 'being a little bitch', in her words, for getting hung up on something she'd said.

Shrugging, you grabbed your water from the fridge. "Well, that's probably true, Ryoubi, but I can't just give up so soon." Taking a swig of water, you savored the cold liquid as you felt your body starting to ache. "Not while I haven't figured out that it's hopeless." Turning back around to slip by her and head to the bathroom, you noticed her eyes traveling up and down your upper body. You'd always been slightly muscular, but now your exercise was starting to REALLY bring out your muscles. Feeling a bit of pride, you slipped by her as you decided to have some fun. Pausing outside of the doorway from the kitchen, you sighed and stretched your arms out a bit, before bringing them back in and flexing your biceps. Stepping forward a bit, you slightly twisted your back, letting your muscles bulge a bit. Turning your head to look back, you saw Ryoubi staring out at you, biting her lip as she watched. Letting out a small laugh, you put your show on hold as you walked down the hall to the bathroom, giving her a small wink as you entered.

Pushing the door shut as you started to slip out of your shorts and boxers, you heard a commotion on the other side of the door as Ryoubi scrambled inside, shutting the door behind her as she started to unbutton her pants. You stared at her blushed face for a while before she responded, "W-what, you pervert? I need to shower too!" With a smile, you flung off your boxers as you started up the shower, stepping inside as you offered your hand to Ryoubi. Finished undressing, she took your hand and stepped inside the shower with you, ready to help you with your 'supplementary' exercise.
