Steven immediately removed himself from her, and her squirt flared up and splashed all over his chest. The man then moved swiftly, turning her on her stomach.
“Stick your ass in the air for me, Sis.”
She did just that, spreading her legs wide; arching her back with a perfectly practiced yoga posture; still drooling both from afterglow and anticipation.
“~I want more~,” she moaned.
“~Bury your huge cock deep inside your big sister, Steven~!”
Steven spat in his right hand and gave her ass a smack. She moaned and deliberately–seductively–waved it in his face.
“You didn’t even have to ask, Sis.”
Steven embraced Selena from behind, plunging his dick inside her cunt as far as it could go.
“~Oh, Steven~!”
He pistoned inside her, relishing her nonstop moans.
“S-Steven, I… I’m going to cu-!”
Steven withdrew his member, leaving her confused and absolutely vying for more.
“Wha-?”
Before she could even utter a complaint, Steven turned her on her side and drove his cock inside her yet again.
“Ah, fuuuck! Your cock’s the best, Little Brother!”
“Look at me, Selena!”
Moaning and turning her head, Selena looked over her shoulder, beholding her brother’s fierce and unrelenting oceanic eyes.
“Are you close, Sis?”
“Y-yes, Steven!”
“I wanna cum with you, so hold on until I give you the signal.”
The woman nodded, repeatedly taking him inside her whilst maintaining eye contact.
“~Y-you’re… amazing~,” she forced out through moans.
Steven groaned, slamming into her even harder, causing her to shudder and produce noises befitting of a porn star.
“So are you, Sis! You’re a goddess! You’re…! Fuuuck… I’m… gonna cum – don’t look away! Keep staring into my eyes, you slut!”
“Little Brother, you’ll make me squirt so fucking hard! Harder than I ever have!”
Steven’s movements picked up, and he gritted his teeth, his balls tightening.
“Shit. The way you moan on my cock – your eyes and that slutty fucking face… I’m cumming, Sis!”
“Give it to me! Shoot it all inside your slutty sister, Little Brother!”
Ramming his cock inside to the hilt and gripping her tightly, Steven groaned. Jets of semen surged forth to flood Selena’s womb. His pupils dilated and he tensed, grabbing her tighter and thrusting inside her once more; draining his balls inside his sister’s wanton pussy.
“Oh, my God! Yes! Fuuuck!!!”
She wrapped her legs around his torso, squirting over and over onto his cock, rocking her hips so he repeatedly pumped inside her, milking him for all he had.
“Give it… all to me! I’m… your whore, Little Brother! I’m your fucking cock sleeve so fill me u-u–u-uppp!”
Her legs tensed… before going limp. She panted, sticking out her tongue with crossed eyes.
Subsequently, Steven felt an unfamiliar heat welling inside the tip of his cock and he promptly–groaning in pain–removed it from Selena.
The heat then spread to his stomach, and he clutched it, falling off the bed and landing on his face. He did not move a muscle after.
His sister stayed panting, gazing at the ceiling. She was enraptured by a lofty afterglow indeed; and she donned a small smile, basking in its extravagance.
“The best sex of my life. Truly.”
She exhaled, going to eye the pool of cum dripping out of her pussy and onto the sheet.
“Seems I’ll be buying a pill later. My, you’re skinny but you sure are packing much more than what I-”
Her eyes scanned the room, bewildered as to the whereabouts of her little brother.
“Steven?”
“Help… me.”
Selena gasped and sprung off the bed. Crouching to meet Steven on the floor, she nervously asked,
“Wh-What kind of prank is this, Steven? Arise this instant.” Panic came into her tone when she said,
“Steven, Arise! You’re aware of how Mom died! This isn’t fun-!”
Steven rose to his feet, his now chiseled back set to her. His hands were raised before him, and he gazed on in awe.
“Steven?”
He turned his head toward her. Gone was the skinny cute boy who could pass as a twink. Now boasting the perfect athletic physique–neither too muscular nor too lithe–with six-pack abs, Steven looked like a man sculpted by a Greek god.
“I guess my abilities finally kicked in,” he calmly spoke. His voice was now deeper; more sure; definitely masculine.
“So I want you to officially register me as a hero down at the Supreme Agency. When our sisters get back, I have a feeling they’ll be just as speechless as you are.”
He smirked, causing Selena to go red in the cheeks and her heart to skip a beat.
“I can’t wait to show them the new me.”
Somewhat regaining her composure, Selena bit her bottom lip, taking in her younger brother’s improved physique with a growing lust. She gulped, feeling a new dampness beneath.
Sending her eyes straight to his face, she somewhat shyly said,
“So, your abilities awakened… because you fucked and came inside me?”
Steven chuckled, holding back laughter. The circumstances regarding his awakening had been much too hilarious.
“Yeah, I guess that’s the funny case.”
He dazzled Selena with a wink, causing her to blush and instinctively–albeit for a split second–avert her gaze.
It was unusual seeing her like that, but Steven immensely enjoyed the sight.
“See, I was right about you being special. Thanks a bunch, Sis.”
“You’re… you’re welcome, Little Brother. You’ve wanted this for so long.”
She smiled – in the interim showing all her pearly whites.
“I’m happy for you, Steven.”
Steven took a step forward, face only inches from Selena’s; looking at her with a smirk; as if she were a prey. She frowned, cheeks going red.
Steven, even before his transformation, stood at a height of six feet. So too did Selena.
Steven rested a hand under his sister’s chin, and planted a kiss on her lips; sticking his tongue inside and wrapping it around hers.
Pulling away, he heard her softly moan.
“What do you say,” Steven began,
“that before we go to the Agency, you get down on your knees and suck your brother’s cock?”
Selena squirmed, seeming hesitant before momentarily acquiescing with the words,
“F-Fine, I’ll suck your… dick, Little Brother.”
At those words, Steven’s cock sprung to life – in all its ten-inches glory.
Getting on her knees with a blushing countenance, she said,
“But we have to make it fast. I’m already late as is.”
Steven nodded with wide eyes, swallowing saliva due to great anticipation.
Selena–eyes twinkling with lust–first kissed the tip of his cock before licking her lips. She wrapped both hands around his member,
one close to his balls, and one at the forefront.
She then took most of him into her mouth, starting slowly, tenderly sliding both hands back and forth on his cock.
Steven couldn’t help it. A moan slipped out.
“Fuck, Sis… that’s… amazing.”
Selena sent her gaze upward, delighted and wildly aroused by her little brother’s words. And it showed in her actions when she got ambitious, removing her hands from his cock to vigorously take all ten inches inside her mouth-pussy. She gagged some, but eagerly moved her head back and forth, causing Steven’s groans and moans to echo about.
The man trembled, staring into her-
‘Eyes. The way she looks up at me as she-!’
Unable to control himself, Steven clasped the back of her head in both hands, thrusting inside her throat.
“I love how much of a huge fucking slut you are, Sis!”
She gagged, reaching four fingers down to finger her drenched pussy as he pumped in and out of her throat – with all the graces of a madman.
“Take it! Take it, my fucking whore of a sister!”
Selena went cross-eyed. His words and repeated, savage throat-fucking sent her over the edge. Water gushed from her pussy.
Merely two seconds later, Steven’s movements vastly accelerated.
“I’m gonna cum, Sis! Swallow everything! Don’t waste a single drop, you brother-fucking slut!”
With one final thrust, Steven groaned with barbarism, his balls tightened, and he shot rope after rope of cum down his slutty sister’s throat.
Selena came again. Sticking her fingers deep inside her cunt while receiving more of her brother’s load, she came again, and again, and again; water spraying all ’bout in quick succession.
Popping his cock out of her mouth, Steven heard her yell,
“Fuuuuck!”
Selena went cross-eyed and her tongue stuck out. She squirted yet again, body erratically moving back and forth whilst she heavily panted. Right after, she fell on her back, almost gasping for air.
Staring down at her with a huge grin–lightly panting himself–Steven said,
“You’re the best, Sis.”
“Fuck,” she muttered, staring at the ceiling.
After two minutes of lying there, after two minutes of Steven watching her,–proud of himself–Selena’s eyes snapped wide open and she yelled,
“I’m so late!”
Activating her superspeed, a sonic boom cruised throughout, shaking the room, yet not leaving any furniture or walls worse for wear.
Within an instant, Selena had cleaned and groomed herself and Steven.
Steven saw his sister–now re-attired in her black suit–pleasantly smiling at him. Her gaze traversed him from head to toe.
“You look good, Steven.”
“Well, no shi-”
She pointed a compact mirror in his face, watching as his expression shifted whilst pocketing the mirror.
“Holy shit, I’m handsome as fuck,” Steven murmured.
Then the realization came.
He raked a hand over his wild, yet now fashionably styled short golden-blonde hair.
