Sit-Ups And Ice Cream

Chapter 1.

Yang was hardly surprised when Weiss refused her offer of accompanying herself and Blake to the workout room that Saturday morning.

"No, you two go on ahead," the heiress said with a wave of her hand. "Ruby and I've got plans to take Zwei on a walk. After all, if you don't give a dog proper exercise, it's detrimental not only to their health and happiness but also-"

"Okay, oh-kay, princess." Yang sighed hopelessly and flipped her hair over one shoulder. "I get it. You need to go out on a date."

"It's not-"

"Okay, Weiss." Yang winked at her, and Weiss' face went red. "You kids have fun then. Blake and I'll be hitting the workout room."

"Fine..." Weiss huffed, crossing her arms before spinning around on her heel. "Ruby, get your coat on. It's chilly out."

"Okie-doki!" Ruby gave a salute as she finished fastening Zwei's leash onto his collar. She then bounded over to her drawers and pulled out a sweatshirt as Weiss selected a trench coat for herself.

Once the two of them were ready, they headed out, Blake and Yang waving after them before the door closed.

Yang turned back to her partner with a grin.

"Now then, what better way to fight off the cold air than with a nice hot workout?"

But her girlfriend seemed significantly less enthused.

"You have fun with that," she muttered. "I'll be bringing my book."

"Awww, really?" The blonde's shoulders slumped in dismay. "C'mon. Blakey. You gotta at least help me out with some things."

"We'll see. But only if I don't have to change."

The Faunus girl was presently wearing thick, black sweatpants and a long purple sweater that hung down past her wrists. Her hair was down as if it could keep her shoulders and the back of her neck a degree warmer, and her ears were slightly drooping. She looked like she would much rather be curled up in bed with a cup of tea on a day like today.

Meanwhile, Yang was in an orange t-shirt and black shorts, her tangle of hair tied back into a ponytail, entirely unbothered by the cool air.

"You don't have to change," Yang reassured her. "I'll just need you to spot me with lifting weights or things like that."

Blake tore her gaze from the pages of her book briefly to meet Yang's eager lavender eyes. She heaved a sigh.

"Fine. But you're warming me up when we get back."

"Of course~"

They headed out the door and toward the student's workout room, and all the while Blake kept her nose buried in her book as she walked.

But it only required one hand to hold a book, and Yang happily held onto the other. She guided Blake to their destination to find the room completely vacant.

"Wow!" Yang whistled. "We lucked out! Usually this place is packed!"

"I think it's because anyone with common sense is back in their dorm rooms or in the lounge drinking coffee by the fire and relaxing..."

"While all that sounds nice 'n all, we can't let this opportunity go to waste."

Yang led her inside, where the air conditioning was blasting. Blake hissed and pulled her hand away from her partner's in order to hug herself tightly.

"Aww," Yang chuckled. "Why don't you work up a sweat with me?"

"As if..."

"Suit yourself~"

Yang went to the treadmills first to warm herself up, and Blake kept to the side of the room, sitting on one of the benches to read. Usually, Yang would observe the other people in the room and do her best to show off. But now that the room was vacant, Blake thought her girlfriend would take things easy.

Of course, she was mistaken.

After jogging on the treadmill for ten minutes, Yang called her partner over to help her with the bench press. She started with ten lifts at fifty pounds, and then had Blake add weights every few minutes until she was up to two hundred pounds.

Blake watched her carefully, her book placed aside and her ears alert as she spotted her partner. Yang's forehead was already beaded with sweat, as were her arms and collar. She was lifting the weights much too quickly and without rest, and it made Blake worry.

"Yang, please slow down."

"I'm fine! Just- ugh... tryin' ta feel the burn!" She huffed with effort as she lifted the bar again and Blake rolled her eyes.

"You're going to be too sore to move tomorrow, you know."

"I'll be fiiiine~"

Yang lifted the bar one last time before grunting, indicating she was finished. Blake helped her place the bar down as her partner slid off the bench.

Yang was comfortable in the cold room now that she was sweating, but it was clear that even in her thick clothing, Blake was shivering.

"Are we done here?"

"Hmmm..." Yang put a hand to her chin as she pondered for a moment. The perfect idea surfaced in her mind just then, and she took Blake's hands, pulling her closer as a spark lit in her lavender eyes. "I need your help with one more thing."

Blake groaned but knew there would be no escape.

"Fine. Let's make this quick."

"We'll see~" Yang hummed in a teasing tone.

She led Blake over to an open space on the floor and spread out a small mat. Yang laid down on her back, crossing her arms over her chest as she lifted her knees up. She looked expectantly up at Blake.

"Hold my feet for me. I promise I'll make it worth your while."

Blake almost scoffed.

"I doubt sit-ups could be worth my while..." But nonetheless, she did as her partner requested, kneeling down in front of her and pressing her hands onto Yang's sneakers. "How many do you plan to do?"

Yang shrugged.

"That-" She lifted herself up until her face was only an inch from her partner's. "-is up to you~"

She placed a quick kiss on Blake's lips before falling back down onto the mat.

The action earned a surprised sound from the Faunus girl, and Blake's ears perked straight up. Yang chuckled and repeated the process, bumping their noses together this time to steal a peck on the cheek.

"So whaddaya say?" Yang purred. "Two hundred sound good to you?"

Blake's cheeks were pink and her ears flattened in embarrassment. But she met Yang's eyes with a challenge.

"Is that the best you can do?"

Yang smirked.

"Guess we'll have to find out."

The blonde continued her sit-ups, every time pressing a kiss to wherever she could reach on her girlfriend's face. She started with one cheek, then went to the other, her nose, her lips – anywhere she could manage.

Sometimes Blake would tease her and move a few inches back, making it impossible for Yang to reach her. Then, on the next sit-up, Blake would catch her off guard and kiss Yang instead.

Most of the kisses were clumsy, but neither minded. Whenever Yang missed, she tried to brush their cheeks together or bump their noses again affectionately.

Unfortunately, they both lost count somewhere along the lines.

Yang lifted herself up breathlessly.

"So like... one hundred-ish?" she asked, kissing Blake's cheek.

"Heck if I know..."

They both laughed, and the process continued a while longer. Only when Yang seemed truly out of breath did Blake deem it time to stop.

"I think that's enough. You're going to be extremely sore tomorrow."

"Mm..." Yang hummed as she sat up one more time and smooshed a kiss to her lips. "You're... gonna have to help me with that..."

She uncrossed her arms only to lock them around Blake's shoulders, falling back down onto the mat and taking her girlfriend with her, pulling Blake between her knees and holding her against her chest. Blake felt herself falling and was helpless to stop it, and she ended up crushing a bit of the air from her partner's lungs.

"Idiot..." she mumbled. "Get your breath back."

Yang nodded, holding Blake in place as she panted.

Blake propped herself up and trailed her hands up to the blonde's face, pushing her sticky bangs aside and wiping her forehead. Heat wafted off of her, and Blake relished the feeling before dipping her face. She kissed Yang's lips, slowing her breathing a little as she helped the other girl focus on something else.

Yang hummed into her mouth, hugging her tighter around her shoulders. She sighed when Blake pulled away, glad now that they were the only two here.

Blake laid herself down atop her partner, resting her head sideways on her collar. She sighed contentedly, listening to Yang's fast heartbeat as it gradually started to slow after the exercise.

Yang closed her eyes, willing herself to fall asleep right where she was.

But Blake forced herself up after a moment, stretching her arms out to either side of Yang's head as she peppered kisses over her forehead.

"Come on. Let's head back."

"Uuuugh..."

"I warned you you'd be sore." Blake sat up and slipped off of her partner before pulling Yang up. The blonde groaned again, falling limply forward into her arms.

"I don't wanna moooove..."

"I can leave you here then."

"No, wait."

Blake chuckled and helped Yang to her feet. She grabbed her book and started leading her dramatic partner back to their room.

Once there, she persuaded the blonde to take a shower to cool off, and Blake read her book as she waited for her. Ruby and Weiss were still gone, so she enjoyed the alone time without the dog.

When the bathroom door opened, Yang stumbled out haphazardly dressed in her sleepwear. It was only noon, but it was clear she wanted to sleep, and so Blake helped adjust her clothing for her before leading her over to their beds. Yang declared she could not make it to her own bed, so Blake sufficed for letting her collapse on hers.

"This works better anyway," Blake mused as she laid down beside her. "Because you'd promised to keep me warm."

"Mm, right, right..." Yang draped herself over her partner accordingly and nuzzled into her shoulder. Blake pulled the blankets up over the two of them, relishing Yang's pulsing warmth for all it was worth.

But her partner was clearly exhausted from her workout session, and her cool shower had likely only served to make her drowsier. Blake felt arms circle around her waist and she pulled Yang in, ruffling her hair.

"Get some rest. I'll wake you for supper."

Yang mumbled confirmation before going limp in her arms.

Blake contented herself with playing with her hair and running her hands up and down the brawler's back for a while.

But the warmth of Yang's body was too cozy to resist, and Blake soon succumbed to a light sleep as well.

The next morning, Blake woke up first.

Ruby and Weiss were curled up together with Zwei on the heiress' bed. After their return yesterday, Blake had woken up and roused Yang so the four of them could eat. But the blonde fell back into bed almost immediately afterward, and it was a miracle Blake had convinced her to brush her teeth first.

Even now, her partner was out cold.

Blake yawned and stretched a bit, finding herself still wrapped tightly in her girlfriend's arms. Her ears perked up soon afterward though at the sound of Yang's snores. Her breaths were raspier than usual, and she sounded congested.

Blake slipped down and pressed an ear to her chest, her fears confirmed when she heard that the flow of air to Yang's lungs was disrupted. Blake sighed, but figured she would let her partner sleep as much as she needed to.

Weiss and Ruby woke a while later, and Blake murmured to them that Yang was probably sick.

"That idiot," Weiss muttered. "That's what she gets for always sleeping with her mouth wide open. This dry air got to her."

"We were gonna take Zwei to Vale again for a walk," Ruby whispered. "Should we stay?"

"No," Blake smiled. "You two enjoy your date. I'll take care of her."

Weiss was about to protest that this was not a date, but Ruby hushed her and led her away. The two of them took turns getting ready in the bathroom before slipping into their warm clothing again, wishing Blake good luck as they led Zwei out the door.

Blake then turned her full attention onto her dozing partner and tucked herself beneath Yang's chin. She allowed a small purr to rise up from the back of her throat.

But it was not long before her purr cut off abruptly at the sound of a cough. Blake peeled herself away and nuzzled Yang's cheek before ghosting a kiss to her lips.

"Yang?"

Another moan, and Yang shifted beneath her. She tightened her embrace on her partner's back before making an attempt to open her eyes, glazed and hazy.

"Ugh... Blake..."

Said girl's ears flattened at the sound of her voice, heavy and slow.

"You caught a cold," Blake murmured. "Should I get you some water?"

Yang sighed, hating the thought of Blake leaving her, but she nodded. Blake placed one more kiss on her lips before she slipped away, stretching as her feet found the floor.

She hurried to the small refrigerator in the room and extracted a bottle before running back to her partner. Placing a hand on Yang's back, she helped her sit up and held the bottle to her lips as she drank slowly.

"Hopefully if you stay hydrated enough, you can get rid of the cold before it really starts. Is the pain bad?"

Yang finished her drink and licked her lips.

"Nah, not my throat, thank god. That's the worst. It's just a bit dry..."

"That's good. Better to nip this in the bud." Blake took the half-empty bottle and placed it aside. "I can make you some soup. It'll sooth your throat. What do you think?"

"Would you feed it to me?" Yang requested.

"Don't push your luck."

But even after she had prepared the soup on their small oven and poured it into two bowls, Blake found she was weak to Yang's pleading eyes; she knew how Weiss felt now whenever Ruby gave her the imploring face.

They're definitely related... Blake thought to herself.

She put her own bowl down as she sat beside Yang, blowing on each spoonful before offering it to her partner. Yang sipped them up gratefully, always offering comments on how good it was.

Blake might have thought the sickness was just an act to have her cater to Yang, but she could tell the brawler's discomfort was genuine. Every few minutes, Yang would grunt or grimace, and when she had just finished her soup, she coughed a little.

Blake patted her girlfriend's shoulder as she ate her own soup, putting the empty bowls on the counter when she was finished. She retreated to the bathroom to get a damp rag, but returned to the room to find her partner doubled over and coughing.

Blake gasped and ran to her side, placing a hand on her back.

"Yang? What's wrong?"

"Ugh- god..." Yang wheezed and blinked one eye open, coughing again. "It hurts..."

"What does? What hurts?"

"Guuhh..." Yang straightened her posture as best she could, leaning back against the headboard of the bed. "It hurts to cough. I'm sore from all those sit-ups... ow..."

Blake felt the panic inside of her start to calm and settle as she realized Yang was not in immense or dangerous agony. She sat down on the bed and chuckled softly.

"I told you you'd be sore."

"Ugh but thiiiis...!" Yang coughed again and groaned. "This really hurts! Damn it..." Her hands went to her stomach and rubbed her abdomen. "I would've been a good kinda soreness if not for this damn cold..."

"You've got to work on sleeping with your mouth closed then."

"Owww..."

Teasing aside, Blake could tell Yang really was in a bit of pain, and she could imagine how it must have hurt to cough on top of the aches from yesterday's workout.

"That's a shame," she sighed. "Is there anything else I can do to help?" She picked up the cloth she had retrieved and started to dab Yang's face.

"Ahhh, feels good..." Yang mumbled. "Actually, it's ironic, but I'm a little hot." She smirked. "Or a lotta hot. That's up for your judgement I guess." She winked and Blake rolled her eyes.

"Well then that's perfect," she said, putting the cloth beside the water bottle on the bedside table. "Because I'm a little cold."

She slipped an arm around Yang's back and encouraged her to lay down again. The blonde coughed a few times, which led to more wincing and moaning. Blake frowned, bending down to kiss her lips, her hair fanning out over one shoulder.

"Does your stomach hurt?"

"Yeah..." Yang confessed. "Don't suppose you could help with that?"

"I think I can," Blake smiled. She slipped into bed beside her partner and kept herself sitting up. Leaning against the headboard, she helped Yang shift a bit, having her rest her head in her lap. "Close your eyes," Blake murmured.

She leaned over Yang again and placed a kiss to the bridge of her nose, then over each of her eyelids. She felt Yang jolt with another cough, but the blonde obeyed and closed her eyes.

Blake purred in satisfaction as she caressed the girl's cheeks, letting the coolness of her fingers leak onto Yang's skin. Slowly, she moved her hands down to her girlfriend's collar, rubbing circles over her chest methodically. Yang's moans only got louder, and it made the Faunus girl chuckle.

"Mm... Blaaaaaake~" Yang sighed, but coughed again a second later. "Oww..."

"Don't talk," Blake chided her. "Just relax."

"Mmkay..."

Blake continued her motions, gradually moving her hands down Yang's sides, over her sore ribs. Despite her efforts to stay quite, Blake's ministrations elicited more moans from her partner.

"Ohhh goddd... Blakey, yer killin' me... in the best way possible..."

"Don't die on me just yet."

After a few minutes massaging her ribs, Blake moved a bit lower, carefully rolling Yang's tank top up a bit to reveal her toned stomach. Her palms slipped over the hard muscles there, the pads of her fingers digging in a little bit.

The moan that earned from Yang was loud enough to make Blake blush.

"I'm glad it feels good, but keep it down!" she muttered, stifling the next potential sound with a swift kiss. "JNPR's going to hear you and get the wrong idea."

"Blake... god... you're a goddess... Keep this up and JNPR's assumptions won't be wrong..."

"Quiet..." Blake pushed another kiss into her mouth before sitting up again. She started moving her hands once more, kneading Yang's sore midsection to the best of her abilities. Yang coughed a few more times throughout the process, whimpering at the pain, and every time Blake slowed her motions accordingly. "Just tell me if it hurts, okay?"

"Nnnno. Blake, you're the best, oh my god..."

The Faunus girl purred in response and continued to rub her stomach. The coolness of her hands melted away the tightness in Yang's muscles, and the blonde felt she might sob with relief as the knots finally started to uncurl.

"Blake... Blaaaake, don't stop..."

She was ashamed at how quickly a blush rose to her face, and the Faunus girl needed to duck her head into Yang's shoulder.

"I told you not to talk like that."

"Mm'sorry... but it feels so gooood~"

"You're killing me."

Blake sighed, but continued to massage her girlfriend a while longer, until the coughing had stopped altogether. She realized Yang had dozed off, and Blake took the liberty of using the cloth to wipe her sweat again, running it over her stomach and collar as well.

Then, she peppered Yang's face with kisses, the purr in her chest full and hearty. Yang awoke to the sound of it a few minutes later.

"Blake... You're a life-saver..." she sighed, reaching her hands up behind the girl's head and pulling her down for an upside-down kiss.

"How are you feeling?"

"Insanely better, thanks to you."

"That's good."

Blake pulled back and Yang pushed herself up with experimental slowness. But her body did not hurt anywhere anymore, all soreness absent and pleasantly so. Blake handed her the bottle of water again and Yang finished it off appreciatively.

"I think I've fended this whole cold off because of you. How can I ever repay you?"

"Well..." Blake smiled coyly at her. "I'm still a bit chilly."

"Allow me~"

Yang pushed Blake down gently onto her back before lying on top of her, throwing the blanket up over them both. Yang smothered her with kisses, earning a loud purr, rumbling and rolling in Blake's chest.

Yang chuckled and kissed the hollow beneath her throat before moving up the side of her neck to her jaw and came to a stop at her lips. They held a long kiss, breathing in time with one another, hearts thumping slowly. Yang could feel the vibrations of her girlfriend's purr, pulling away a moment later to nuzzle Blake's cheek.

"So..." she huffed. "You still cold?"

"Of course not," Blake replied. "But you're not allowed to leave this bed until you're better."

"No complaints about that," Yang hummed.

"What about you?" Blake asked. "Are you still hot?"

"Hmmm~ you tell me~" Yang stole another warm kiss, pressing closer to her. When they parted, she looked down at Blake, her golden mane of hair making a curtain around them on either side. "So? Still hot?"

Blake breathed hard for a moment as she considered her answer.

"Fairly," she diagnosed. "But you're hottest when you're together with me."

"Oh, ain't that the truth!"

Another kiss, and they both knew there was no more possibility of sickness, only a warm, lazy end to a Sunday afternoon.
