"Wait, what're you-?"
Seeing bloodlust in his sister's eyes, goosebumps shrouded every facet of Steven's body.
"Si-Sis! Wha-?!"
Selena's right-handed fist breezed past his face, and from the shockwave that followed, the mountain behind was blown to kingdom come.
Turning the panic-stricken Steven's head in the mountain's direction, she smiled as he paled.
"You... were this strong all along, Selena?
"I'm an operative of the Supreme Agency, Steven. Most heroes and villains can't come close to my level of power."
In quick succession, he inhaled and exhaled, still can't believe what he was witnessing.
"You know," she spoke,
whispering in his ear,
"I think you can take that punch."
"Are you insane?!" he shrieked in dreaded horror.
The laugh of his sister rang in his ear, and before he could speak another word she'd already created some distance between them; some feet away.
Clearing the distance, she reeled back her right arm; slowly this time, and she roared, giving her absolute best.
"Ahhh!"
While his scream echoed about, Selena's fist went to strike his face, but instead, it seamlessly slid through - akin to the effect of punching a ghost.
His clothes fell to the ground, and his sister's eyes widened. Selena puffed out--trembling--while retracting her fist.
"Steven..."
"Holy shit, Selena..."
"Why... do you have my unique ability... and every other ability I possess? And after cumming inside me, no less?!"
Steven paid no mind to his sister's words, gazing at her in terror as one would a monster.
Noticing his apprehension, Selena reached out toward him, quietly calling,
"Steven."
He backpedaled, gulping.
"You," he whispered,
"actually tried to fucking kill me, Selena."
Selena closed her eyes. Inhaling, she unfurled them to say,
"That punch of mine was going to be but a light tap. Why else do you think it was approaching so slow, Little Brother? I merely wished to uncover your unique ability."
He pursed his lips.
"Ah."
He burst out laughing.
Selena giggled.
"Holy shit, Sis! You almost literally scared the shit out of me!"
His sister began laughing alongside him. Shortly, they stopped. Steven was beaming. Selena's face was contorted into an expression of lust and intrigue, however. His naked body distracted her, and so--before he knew it--she dressed him.
"Steven, you have all my abilities; albeit to a far lesser degree."
Losing his smile, Steven nodded.
"Hm-hm."
"And you attained them, this new physique, right after finishing inside me."
"Hm-"
His sights grew expansive.
"Wait, are you saying my unique ability's-?"
She gave him confirmation, crossing her arms with a nod.
"Correct. Fucking me gives you my abilities, and mine alone, it seems. The maid, that Darlene: her unique ability allows her to hear the desires of others in her proximity, yet you clearly hadn't acquired that ability upon fucking her, for she had first told us it spontaneously activated out of the blue in the beginning. I alone give you strength."
Steven smirked, visage teeming with excitement.
"Awesome. So you agree that I was right, yeah? You really are... something truly special, Sis."
Selena blushed, involuntarily beaming and resting her arms at her sides.
"Look who's speaking of special, the man who gains his sister's abilities upon cumming inside her."
Something about her words stuck with Steven. He placed a hand under his chin, and thoughtfully gazed off into the distance.
"Selena, do you think it's only because you're my sister?"
"I'm not su-"
Realization crossed her features, and her mouth went agape.
"Steven, you're not thinking it's possible to, too, gain our sister's abilities by cumming inside them, are you?"
"I don't know. Maybe."
He threw a wry smile her way.
"Why that face? Feeling jealous, Selena?"
Profusely blushing, she scoffed.
"Please. I'm a grown woman, Steven."
Steven stepped forward, causing her to look unsure.
"You're right."
He put his forefinger before her face, letting it waver before her slightly parted lips.
"You're right, you are a grown woman. One who gets off at the thought of her precious little brother beating his dick to her."
Lust over her almost sedated countenance, she murmured,
"Yeah."
Before the elated Steven could run his mouth, Selena drawled with panic creasing her features,
"Anyway... Before you'd raised that question about our sisters, I devised the hypothesis that you harbor the ability to evolve each time you cum inside me."
Looking enticed by that idea, Steven voiced with a grin,
"Well, I'll be a sisterfucker."
Selena closed her eyes, unable to hold in the chuckle that rolled from her lips after.
"Okay. Very clever. But only after I'm done with work. I'll be sure to book motel rooms for both of us each night. Can't have the other girls finding out about our... special relationship."
Eyeing her deeply appealing cleavage, he said,
"Wholly agreed, Sis."
She rolled her eyes with a smile.
"Anyway, we're done for the day."
The sound barrier broke, and they stood before the elevator in the blink of an eye.
She strolled inside. Her brother followed.
"You'll meet my supervisor, be given your hero rank, as well as the option to choose your hero name."
"Awesome."
"And, just to be on the safe side, your unique ability will be listed as 'Intangibility'. My supervisor seems nice, and I think he's nice, but I don't trust him one bit. Who knows what they'd try--what Christina Vale--would try, if they thought you carried such an ability."
Steven gave her fat ass a nice squeeze, causing her to go, "Ooh" with widened eyes. She then lightly breathed out,--whimpered--clearly aroused.
"I appreciate it, Big Sis," he sensually whispered into her ear.
"I appreciate you. You'll get a real nice fucking later. I guarantee it."
Selena slowly, somewhat nervously nodded. She squirmed, rubbing her thighs together; her panty now damp with her pussy juice.
"Steven, you're... really making me too horny. At least wait unti-"
Leaning back and defensively raising his hands, he said with a smirk,
"Fine. Fine. The teasing stops. For now, Big Sis."
She moaned, surprising herself and bringing out great joy from Steven.
Quickly, and in a very obviously fake way, the woman scoffed.
"Anyway... To the office of Supervisor Erron Ridley."
The elevator door shut, and it instantly went down. Once the door unfurled, the siblings stepped out in tandem, seeing a chubby red-suit-clad African-American sitting at a desk; his smile warm. He certainly appeared to be in his early thirties.
"Please," Erron said,--his tone sophisticated and posh--gesturing at the two chairs before him,
"have a seat."
Steven and Selena started over to him. Steven sat, whilst Selena handed Erron her clipboard.
The woman took a seat thereafter, elegantly crossing one leg over the other.
"Ah," Erron's voice came out, a little eager,
"your younger brother, I see. And he also shares your abilities. A very rare occurrence - even among blood relatives. Extraordinarily pleasant indeed."
He took his eyes off of his clipboard to place them on Selena, then on Steven. He frowned - though there was no emotion in that frown.
"Mr. Price, should you put in the effort to improve your strength and prowess, you have the potential to be a highly valued asset of the Agency, as very few are gifted to hold an ability such as intangibility. However, with these-"
He briefly checked the clipboard.
"statistics... I'll be brutally honest in saying that you're average, Mr. Price; and at best, above average."
Selena pursed her lips, closely watching her brother as he impassively breathed out, saying,
"I know. So, this means I'll start out as a White-Hand hero, yeah?"
Erron clasped his hands, shaking his head.
"No, Mr. Price. Your unique ability alone places you aloft the second rank. You'll be assigned the third rank - a Green-Hand hero."
Steven didn't seem too surprised, though a small smile came on his mug nonetheless. That, in turn, made his sister happy.
Unclasping his hands, Erron rested the back of his hand on the table. From within it, green threads appeared and stitched itself into a bright green scarf filled with tiny illustrations of many transparent hands.
As soon as Erron set that scarf down, Steven hastily picked it up, star-eyed whilst eyeing its totality.
