The "Parasite" option

You made a fist with your right hand and looked up at the goddess of hotness above you. You smirked and thought to yourself all of the fantastic ways you could defeat her with your godlike ability to manipulate reality. However, the one idea that kept popping into your mind is the abilities of Parasite, the superpower of absorbing another person’s, this case a girl’s, power and strength.

You shift your shoe to the right and jump forward, using superhuman momentum to charge at her. She deftly dodges, causing your hand and feet to make impact into the side of an adjacent building, slowing your momentum to a stop. You see her form fly down beside you, levitating out of your reach, “I simply am unsure what you are, but I have underestimated you. However you certainly have done the same for me!” She zooms in to give an earth shattering punch, which in fact makes it impact. It hurt but she failed to stop your right hand from grabbing her left shoulder. The impact of the punch forces you through the brick side of the building, but your grip is to strong, and the Kryptonian is pulled in with you, both of you tumbling across the office buildings floor, smashing through several cubicles. The building was empty from what you could see, but you were more focused on the girl beneath you right now.

Supergirl shakes her head and sees you pinning her arms. Her face sours, and positions her legs beneath your torso in a quick move and kicks you off, making you fly back. She had yet to know that you had already taken what you needed from her. You get to your feet, to see she had put her fists up, but had a expression on her face that spelled confusion. You grin and put your fists up as well. Using her ability of flight, she charged forward at less than an impressive speed. This allowed you to block her fist with ease, allowing you to headbutt as a counter. She gives a painful gasp in shock, as she flies back, smashing against a water cooler. The cold water splashing onto her chest caused a fun reaction for you, a wet top, which showed her breasts and hard nipples. She looks down and scowled at you, “You will pay for that!”

She got up and you simply put your hands up chuckling, “Hey didn’t mean to do that, so sorry! Let me help you!” You focused your recently absorbed heat rays right on her top. Her blue top first dried, then ignited into a burning inferno. You laughed as you saw the look of panic enter eyes, as she stopped, dropped and rolled to put out the flame. When she was safe, she stood up covering her supple breasts which created a nice amount of cleavage, making you really want to see what was beneath more! You also enjoyed how her outfit managed to stay the same otherwise, her cape looking untouched by the flame.

After stopping panting, Supergirl pointed her finger at you, “Wait a second, the heat-vision, my decreased strength and speed... Are you stealing my damn powers? Oh I better kick your ass quick!” She went back into battle pose, and positioned her fingers to say, “Bring it on!”. It had less of an impact by the fact that she was still covering her chest with one hand.

You loved fighting this weakening Supergirl. You cracked your knuckles and approached slowly. She paced slowly, moving every step very concisely in an attempt to think of strategies against you. You just couldn’t take it any more, and ran forward, which she quickly dodged away from, and threw a counter-punch. Thanks to your super-speed though, you were able to catch this punch, and crush her fist under unbearable pressure. She cried out in pain as you grabbed her other hand, causing her breasts to bob free without restraint. You lick your lips as you enjoy the feeling of power sucking into you, you drop one of her hands and put one of her tits into your mouth to bite and tease with your tongue.

With her now free hand, she takes advantage of your disinterest in her fight with you, and punches you hard on the side of the head, which nearly breaks her hand. She screams out in frustration, she now realized you have absorbed much too much of her strength for her to fight back anymore. You let go, Supergirl falling hard on her ass as she looks on the verge of tears in frustration. You lean over and laugh in her face, “I told you! You want to be my sex ****. You couldn’t even muster up the strength to fight back! Now let’s all tell the truth, you want to be my sex **** right?”

She looks up at you with a look of pure hate, “Screw you pig!” She spits blood on your shoe.

You look at the red mark on your runners and sigh, “Alright, just say 'I want to be your sex ****, Master.' and I will stop..."

She looks at you in confusion, “What will sto-”

Your grab her pretty face and smash it into the floor. Tightening your grip, you then run the face through many of the cubicles, Supergirl’s weak form crying out in pain as she hit every one of the gray walls. You then push her through one of the floors large window, causing glass to cut her skin, and causing you both to hurtle to the ground. The wind **** run past your ears, as you watch Supergirl weakly punch your arm in desperation. You make impact into the asphalt, creating a huge crater in the middle of a busy street. Supergirl’s mouth coughs up more blood, and you just sit on her stomach, mashing on the girl’s tits, enjoying their softness between your fingers. She lifts her head up weakly, “D-damn you...” she mutters before her head falling back

“Well that probably kinda-sucked for you! Anyways just say the phrase, and the pain stops... and my pleasure begins!” You scoot back and pull her super-panties to the side making you lick your lips, you trace your finger up her slit and feel the clit.

Supergirl moved her head up again, and tried to spit blood on your crotch. You were too fast however and you covered mouth, forcing her to swallow. You stand up frustrated, “Alright, alright, you are in the closet about this. Well if you don’t say it, I might have to move on Supergirl! But who would it be?” You zoom over to a blonde female bystander, a true Milf in her late 30s with an over-exaggerated hourglass figure stuffed into a green mini-dress, struck in fear as a villain is beating a hero in front of her. You pull her up by the left arm, “Here is the thing, Supertits, I am fuckin’ horny! I need to relieve myself again and again until I am sated. So if it is not you, I suppose it will be her!” You rip her mini-dress over, admiring her curves. “Supergirl, do you know what happens when a powerful meta-human makes love to a damned mortal?”

Supergirl weakly gets to her feet, “St-Stop...Ple-please, Just...leave her alone!”

You smirk, “You know how to end this Supergirl,” you say giving your ultimatum, “SAY IT!”

She bows her head and gets on one knee, “I want to be your sex ****, Master.” Her voice cracking as she muttered those hated words of hers.

You give a clap of your hands as you walk over to her submissive form, grinning a perverted smile, “Oh bloody good show ****! The truth will set you free! Now let’s go somewhere more private no?” You were still holding the attractive female and looked back at her, “Oh yeah Superslave? Keeping this hottie for fun as well.

Emotionally crushed, she looks up, “But I thought...”

“No, I said she wouldn’t be a sex ****, I can use her for anything else!” You then grabbed her sweet, smooth hair and pulled her to her feet, “We are going now!” Still holding onto her hair, you flew at incredibly speed up and into the horizon.
