Beads of sweat formed on her forehead as her eyebrows knitted together deep in focus and concentration; each bead traveling down the flawlessly smooth alabaster skin and allowing itself to be soaked up by the cotton bandana obstructing her. Her raven hair was drenched from exertion causing a few rogue strands to stick to her cheek as the rest of the moisture trekked down the nape of her neck and the crevices of her collarbone; adorning her skin in an immaculate glistening perfection.

Her muscles strained beneath her youthful skin in anticipation as she crouched to get better footing. Her ears were finely tuned to the sounds echoing around her; heightened only by the temporary loss of her eyesight. She could hear the faint breathing of her would be attacker reverberating through the enclosed unit.

The smell of sweat and stale cigarettes filled the air as she turned her hearing towards the sound of light footsteps slowly coming up behind her. Her heart pounds within her ribcage and adrenaline coursed through her body as she prepared herself for what was coming next.

The first attempt of an attack was shattered the second she felt a shift directly behind her; hands tapped the padding of the mat lightly below her, sending vibrations through her feet. She effortless flipped sideways out of the missed leg sweep and landed in a crouch preparing herself for yet another inevitable attempt.

Within seconds, a strong, hairy forearm grabbed her tightly around the neck threatening to immobilize her. She allowed herself to be dragged backwards by the brute strength of her assailant. Focusing on the techniques she's learned through years of countless training, she quickly calculated the ways she could break free from the boa like, air constricting grip.

Placing her hands tightly over his hands, she felt around blindly for a finger only to bend it violent back to loosen the tight grip. Planting her feet, she shifted her body weight forward while grabbing firmly onto the arm of the attacker and shifting her weight again to support his on her hip, she flung him over her shoulder in a fluent hip toss. After expelling the breath she held to support his weight, she was down on top of him. She scrambled eloquently before acquiring his arm firmly; throwing herself roughly against the mat beneath her and threatening to pop an elbow out of it's socket.

She didn't let go of the hold until a hand frantically tapped her calf muscled as her legs clenched tightly around the downed attacker's shoulder demanding a submission or risk being snapped in half. Letting go and working her way quickly to her feet, she yanked off the blindfold to reveal vibrant green eyes that stared in amusement at her downed martial arts instructor.

"Remind me to never encounter you in a darkened alley, Lena." Groaning and getting himself slowly back to his feet, he hunched over grabbing his elbow to rub out the soreness and huffing deeply in an attempt to gain air after having being winded by the toss.

Smug as ever, Lena skips lightly over to the corner of the studio; grabbing a bottle of room temperature water and a towel she had placed next to her gym bag and helmet upon arriving. While drinking and dabbing the sweat from her neck and forehead, she stared at the instructor as he continued to fight to get air into his lungs. "Looking kind of old there, Mack."

Finally standing at full height, Mack walked over to Lena before grabbing a spare bottle of water. "I taught you well. Too well to be honest. It'll make it a hell of a lot harder to kill you that's for sure." His thick Boston accent broke through when he spoke.

"That's what I'm counting on." Lena continued to dab the sweat from her chest before it joined the rest of it's family who resided at the top of her sports bra turning the once light grey color dark when she heard the shuffling of feet a few paces behind her.

"Alright, enough with the cocky shit, Luthor. Think fast!" Mack roared while hurling the open water bottle at her.

She successfully managed to swipe a firm arm sideways knocking the bottle and it's contents against the wall at the end of the studio. Within seconds, Mack was directly in front of her with both hands grabbing at her forearms. With quick, cat like reflexes, she threw all her force forward causing the trainer to bend before delivering a stiff knee to his chin. Deciding to add some insult to injury, she grabbed onto his arms for support as she tossed herself back in a small fluent motion; both of her feet connecting with Mack's chest as she kicked off sending the trainer a full five paces backwards onto his back before landing in a perfect crouch after an impressive backflip.

Laughter filled the studio as Mack stared at the ceiling, a hand firmly on his chest where the blow had made contact. His laugh rumbled throughout the windowless basement gym and Lena stared as she stood up from the crouch and crossed her arms defensively over her chest.

"Now, what might I ask, is so fucking funny? Enjoy getting your ass kicked after a cheap shot like that?" Her anger peaked through and she wanted nothing more than to continue her assault on him after such a cowardly act from such a reputable opponent.

Mack moved onto his side and rested his head on his hand looking every bit nonthreatening even though pounds of muscles bulged effortlessly under toned skin. "You think that cutesy, Spiderwoman bullshit is gonna help you out there? You think dragging that flair bullshit into a fight won't get you killed? You're good Lena, but this ain't Vogue, baby. Strike a pose out there and your ass is grass in two point five seconds and all this training would have been for nothing. You can't finesse your way out of everything."

Lena raised an immaculate eyebrow and smirked. "Are you upset that I just laid your ass out with some style? I took what little you taught me and made it better."

Mack smiled. His eyes crinkled at the corners giving him a more juvenile look rather than revealing his true age. Two deep dimples adorned his cheeks as pearly whites shined bright making his deep tan appear much darker. He pulled his hair out of a very thick man-bun allowing his hair to fall in tendrils of dirty blonde waves just above his shoulders. "Don't forget, you might be a junior black belt in Karate, brown belt in Brazilian Jujitsu and a fucking deadly little devil in Muay Thai, but I'm the Master here, ducky. Cut that cocky shit out. You were lucky this time, but next time, you might not be. I taught you skill, but out there, it's dirty."

Lena stepped closer to her instructor until she towered over him. A smirk spread across her face as she stared down at him with intimidation. "Oh believe me, Mack, I am plenty capable of fighting dirty," her slight Irish accent poking through.

"Yeah, whatever you say, dollface," Mack responded before laying fully on his back with his arms resting underneath his head as a makeshift cushion.

Mack, like everyone else in her life, loved underestimated her abilities and all it did was light a fire under her. She lifted her leg and moved over his body and stared down at him. She might be just twenty years old, but she learned early on that she had been equipped with a relentless attitude and with the insatiable thirst to prove herself.

Lena dropped to her knees landing roughly on Mack's stomach unexpectedly earning her a groan as the air escaped his lungs in a rush. Mack eyed her suspiciously as he inclined his head to get a better look at his gorgeous protégé. Lena smirked as she lifted her sports bra over her head exposing her perky, full breasts to the shocked and awed teacher. "What's the matter, Mack?" she asked as she reached her hand backwards to grab his semi erect member through his sweatpants. "Too much for you?"

In a haste, Mack grabbed her by the waist and pushed her firmly to the ground as he crawled hungrily on top of her. Lena's hands came up to the back of his neck pulling at his hair. He groaned as her hips bucked slightly grazing his erection before he silenced said moan by eagerly ravished her neck.

Lena moaned and smiled broadly knowing she had won as she stared up at the ceiling focusing on the patterns of cracks that littered the once pristine surface while she waited. Mack's callous ridden hand groped at her breast threatening to bruise her porcelain skin as the others moved slowly towards the waistband of her tights.

She bucked again creating some space between them and in an instant, a firm knee connected with Mack's member causing him to yelp in pain and collapse sideways off of her.

Lena moved quickly onto her feet and grabbed her formerly discarded sports bar off of the ground. She watched in amusement as Mack writhed in pain; both hands tucked protectively between his legs in a feeble attempt to alleviate the excruciating pain. Walking over to her downed master, she knelt down and chuckled humorlessly. "How dirty was that for ya, mate?"

"That was cold blooded, Luthor," he groaned through gritted teeth as sweat and tears poured from his face and onto the mat.

Lena skipped toward her gym bag while spinning her bra carelessly on her index finger; her breasts bouncing with every step she took. She threw the bra into her bag and pulled out her leather jacket before throwing it on and zipping it dangerously below her breast. She picked up her bag and motorcycle helmet from the ground and headed for the door. "You should really get that little guy checked. Expect payment in your account at the end off business day tomorrow and I'll throw in a few thousand extra for your medical bills." She pulled open the door before turning to Mack again, "It pains me to say, but our partnership has hereby been dissolved. I've learned all I could from you and let's face it, Mack, you've outlasted your worth to me. See you around, Master."

She walked out of the studio without sparing her now former sensei a passing glance. In her heart and mind, she knew he made three fatal mistakes today making him utterly useless in her life. For one, he antagonized her. Secondly, he underestimated her. Lastly, he forgot that although she separated herself from her family's nefarious activities, she was still very much a Luthor.
