Proof

Kara collapsed to the ground when Luthor freed her from her chains.

• Tell me what you deserve for having stood in my way so many times. Prove your conversion and obedience to me.
• I deserve all the punishment you wish, Master. I could never forgive myself for having prevented you from your plans. I was too foolish to understand your greatness.

Luthor smiled.

• You will prove it to me immediately. Tell me how many lashes you deserve to be punished.

Kara was lost.

• As many as you want, Master.
• I want a number.
• At least 100, Master.

Luthor nodded. He picked up a nine-tailed whip.

• Stand up, attach your leather handcuffs to the chain on the ceiling.

Kara swallowed. She had never felt so fragile without her powers. She obeyed, attaching her leather bracelets to the chain. He viciously aimed for her breasts.

The blows rained down mercilessly, Luthor raging into a trance, the whip becoming an extension of his body in a dance of hatred and intoxication with the power he held over his enemy, now at his mercy.

The whip slammed down once more, tearing the air before wrapping around her waist with a wet crack. Kara gritted her teeth, her muscles straining against the cuffs that pulled her arms toward the ceiling.

Luthor clicked his tongue, admiring the crimson welts already marking her skin. "Fifty-seven," he murmured, like an accountant jotting down figures. His hand caressed the fresh burn, making Kara shudder beneath his touch. "You're shaking.

Kara, without her protection, was nothing but a torment of pain and suffering, yet she screamed.

• Sorry, sorry, Master, yes, I deserve my punishment.

Afraid, Luthor admired the marks on his victim.

• We'll continue later for now.

He moved behind Kara, dropped his pants, and penetrated Kara viciously after slipping a latex ring covered with rigid plastic spikes around her sex. Kara's cry brought a smile of victory and satisfaction to his face.

Kara screamed, her body arching violently against the brutal intrusion. The spikes on the ring scraped her flesh with each of Luthor's movements, turning each thrust into burning agony. Her fingers tightened around the chains, knuckles whitening with the effort to contain the pain.

"Look at you," Luthor growled, gripping her hips with an iron grip. "The great Supergirl, reduced to moaning like a female dog."

He began to thrust in and out, pushing him out and in with brutal thrusts that **** her sex all at once.

• Ah yes, master, I'm your female dog, ah yes, again, ah.

Kara's moans broke into broken sobs, each thrust of Luthor's hips pushing the spiked ring deeper, brutalizing her sensitive flesh. She felt the latex scrape against her walls with each brutal withdrawal, the nubs leaving behind a dull burn that intensified with the slightest friction. Her thighs trembled, her knees threatening to buckle, but the cuffs held her upright, mercilessly offered.

Luthor quickened his pace, his nails digging into Kara's hips like claws. The smacking of their flesh joining echoed through the room, mingled with Kara's hoarse gasps. A trickle of saliva dripped from the corners of her lips, her pupils dilated with pain. The humiliation, but also the pleasure of satisfying her master.

The latex ring covered in spikes clinging to her already inflamed walls triggered a new sensation in Kara. She was free of the responsibilities that had until then crushed her. She only had to submit and surrender to her master. She was free in a way, no longer accountable for her actions to her cousin, to the Justice League, to the world.

Her very body no longer belonged to her; she began to wet despite the pain.

Luthor felt her body contract around him, the spikes cruelly stimulating his nerves with each thrust. He burst into a hoarse laugh as the wetness revealed his own body's betrayal. "Even your sex pays homage to me, Supergirl," he growled, digging his fingers into the flesh of her hips, leaving bluish marks, like an echo of his words. Kara had an orgasm like never before. This hadn't happened to him.

Kara moaned, tears streaming down her face as her stomach tightened under the onslaught. Luthor managed to resist for several minutes before coming gloriously inside Kara, who now only let out weak moans, her body trembling with exhaustion and submission. Luthor withdrew with a satisfied groan, leaving the bristling ring in place, its cruel weight reminding Kara of her condition.
