This story is set within the MCU and takes place before the events of Thor Ragnarok. Part 19 of my 'An Avenger's... Series' but enjoyable out of context!
...
Landing hard on her shoulder Captain Marvel winced, face pressing against the mat where she had fallen:
"I slipped..."
Feeling far less playful the Lady Sif remained in a combat ready stance as she glowered down at her winded sparring partner. Standing in one of the bright golden halls of Asgard the warrior was proud of the advantage she had gained against her unassuming opponent. Fists clenched the statuesque brunette waited impatiently for the other woman to rise once more:
"Only as a result of me punching you in the face..."
Rolling her eyes impetuously the cosmic Avenger quickly stood, blowing back her long blonde bangs as she replied:
"I slipped and you happened to punch me in the face; the two events are not related."
Sif shook her head; Carol could never admit her own faults even when training. Of course the Captain liked fighting Asgardians; few other beings in the Universe could land a blow and only the Goddess of War could knock her down. But if she denied her own fallibility how could she learn?
From the outside it would appear an unfair fight; the taller brunette dressed in full red and gold Asgardian armour; metal plates gleaming in the orange light of the grand hall whilst a sword hung from her hip. The short blonde meanwhile wore only skin-tight fitness attire meaning much of her arms, legs and even midriff were exposed to the warrior's fists. However, within the unassuming girl there was hidden a well of cosmic power that could burst out at any time. Sif knew better than to take it easy on Captain Marvel.
Carol could tell that something more than her denial was bothering the uptight Asgardian; even by her usual standards Sif was tense. Of course, the warrior woman wouldn't spill her secrets. Unless she was distracted by a skilled opponent...
Launching herself forward Sif threw a punch only for Carol to quickly dodge aside. Fists flying the blonde blocked each attack in turn, moving sinuously backward to deflect the harsh strikes. Finally catching a swinging arm Carol slowed the incoming barrage; the two wrestling for control. Breathing heavily Sif was annoyed this girl hadn't even broken a sweat, questioning the arrogant Captain as they fought in place:
"Ugh-what would you sacrifice to save Hala? Ugh-Xandar!? Ahh-your precious Earth?!?"
"I don't believe in sacrifice," Carol replied carelessly, "if I come across a threat I blast my way through it!"
Twisting out of the Asgardian's grip Carol spun; delivering a flying kick that Sif just managed to duck. Again thrusting forward the brunette stayed low, using her opponent's power and predictability against Carol. Diving, the warrior caught the blonde's flailing arm before twisting it up her back; the two women suddenly finding themselves in a much more intimate spooning position:
"You know the 9 Realms cannot be simply 'blasted' into submission??"
"I'm literally the most powerful woman in the cosmos." Carol replied confidently.
Glowering at the Captain Sif slapped her tight little ass:
"Well you fight like a girl!"
Finally released from the hold Carol grimaced; offended by Sif's insinuation of her weakness, even if she was right! Facing off once more the two women circled each other:
"A skilled warrior should not be so distracted by her pride and vanity, you should believe in discipline and sacrifice!" Sif explained: "There are others around the universe that could match your power; Gods, Witches, Titans, Celestials... will you be ready for all of them??"
Frowning Carol responded shortly:
"What are you so afraid of??"
Casting her gaze downwards, Carol recognised a rare moment of vulnerability from the Goddess as Sif considering the uncomfortable question:
"I have had bad dreams of late... Ragnarok is coming; the end of everything! And without Thor as our King, we will need you in the fight-"
Having waited until Sif was distracted Carol launched forward delivering a powerful cosmic blast to the Asgardian's exposed breastplate. Thrust backward through the air the brunette crashed down onto the mat several seconds later.
"Ugh..." Groaning Sif found herself on her back just as Carol had been before:
"You know that's cheating..."
Flaunting her power the Captain blew on a smoking fist, smirking down at the fallen warrior:
"You're right Sif. But if you want to delay Ragnarok its not me that's going to have to make the sacrifice..."
Offering the brunette a hand Sif saw a chance to take advantage; Carol was not the only one prepared to fight dirty. Grasping her forearm she tugged the Captain downwards. Springing off the mat the brunette flung her hips toward the blonde, wrapping her toned thighs around the other woman's head. Twisting them sideways Sif brought her obstinate opponent slamming down onto the floor once more.
Not letting up Sif rolled them over; planting herself on top of her surprised opponent and mounting the smaller blonde. Tightening her abdomen she pressed against Carol; pinning the Captain's wrists above her head:
"Submit!"
Taken aback by Sif's deception, nevertheless Carol shook her head stubbornly:
"Never!"
Wrestling against each other Carol felt the brunettes' cold metal breast plate press against her more exposed chest, sports bra failing to hide hard nipples. As ever the cosmic blonde was aroused; a fun side effect of her infinite cosmic power and Sif's distracting proximity wasn't helping. At the same time the Sif could feel the Captain's bare leg squeezed between her thighs; knee shoving up against her sex. For the two eager combatant the battle was just beginning...
Sif gasped, lashes fluttering as that insistent knee pressed against her vulnerable core. In-spite of her indignation she could not deny their brutal friction was delicious.
Registering this reaction Sif pressed her momentary advantage; using the Captain's insatiable appetite against her. Thrusting into the Carol's core she watched the woman tense, blue eyes crossing. Unfortunately for the warrior woman, two could play at that game and the Asgardian was caught off guard when the blonde leant up to kiss her:
"Mmmpph!!"
Immediately muffled as the impertinent women captured her face, lust and confusion held them together in a smouldering embrace.
Finally peeling herself away Sif scowled down at her infuriating opponent:
"How dare you kiss me!?!"
Diving forward Sif took over; lips enveloping Carol's as she tried to take back control:
Falling back onto the mat Carol's lips parted so Sif's tongue could slip inside; battling with its counterpart. Literal sparks flying from the cosmic blonde Sif enjoyed the sharp tingling that came with her mounting pleasure.
Squirming as the kiss deepened, the two women flexed together: the warrior's womanly curves gliding against Carol's lither frame, dark and light hair blending in the orange light.
Sif rationalised this encounter was just the distraction she need; the perfect way to blow off steam as she prepared for Ragnarok. Little did she know this diversion was the beginning of the end for her world...
