#12

  Celestina was struck dumb by what happened. She could not believe what was happening right in front of her.

  Her eyes opened wide, and her jaw hung in disbelief as she stood rooted on the floor, watching as her girlfriend started sucking her brother. Celestina knew she should pull Julia away from her brother before something bad happened. But despite knowing that, she remained stiff and motionless as though petrified.

  Celestina’s body became even stiffer when she suddenly noticed her brother grabbed Julia’s head and his hips started moving, faster, thrusting against her girlfriend’s face.

  She was not angry because her girlfriend was cheating on her brother in front of her, but rather, she was shocked to see that her brother was feeling it.

  She expected him to scream in anger and push her away, not grabbing her head and moving his hips. He was even moaning happily as if he was feeling pleasure.

  …well, I know that her mouth and tongue do have skills,… but is that enough to pleasure my woman-hating brother?

  Celestina forgot to pull her girlfriend away and just watched in amazement as her brother - looking very excited- piston his hips against her girlfriend’s face, gulping.

  Julia was damn good!

  William tensed his thighs and moaned. The bunny-eared bitch was sucking him in deeper and deeper not stopping when he bumped into a slight resistance at the beginning of her throat, not even when her eyes started to redden and tear up with hidden gags, going until she physically could go no more, her nose buried in his pubic hair, mashed against his skin.

  God, he felt like a fumbling teenager again, with grunts falling from his lips and even a few errant moans breaking free, his eyes falling shut as she began to bob her head, barely pulling off his cock before sucking him in again, the filthiest sounds coming from her tightly sealed lips.

  He was so lost in his pleasure that he didn’t even concern himself about his sister - who should have been Julia’s lover - standing on the side and watching, his fingers in her hair tightening and forcing her to take up a faster pace.

  Julia started coughing a little, gagging and sputtering, and he almost stopped, before she completely cut those noises off.

  It was almost like she didn’t need to breathe through her nose anymore, able to take him down deeper than anyone before, faster than anyone before, and most certainly better than anyone before.

  Her right hand suddenly found its way down his ass, the shocking action causing him to flinch forward, her forehead bumping into his lower abdomen. But William didn’t mind it as her fingers massaged the muscles of his behind expertly. She was kneading them like she was kneading dough- although it should not be as soft as a woman’s butt, after all, he’s all lean and muscles.

  Nevertheless, William found all of this too much.

  “Fu-uck…”

  He grunted, abandoning all rational thought as he fucked into the girl’s throat.

  “Shit, Julia, I’m about to–”

  He tried to warn her.

  But Julia did not care for his warnings; instead, she doubled her efforts, slobbering on him wildly.

  “Fuck, fuck, fuck…”

  He murmured like a prayer, the hand previously helping to hold him up leaving the sink, grabbed her hair, and pulled her head violently at his crotch, his orgasm almost knocking him out.

  Each rope of cum he shot deep into her stomach- Julia happily swallowed down, the muscles of her throat massaging him into oblivion, his sight turning white as his eyes rolled to the back of his head, his entire body shaking and flinching with each pulse of his cock, all of which was met by another suck of her lips.

  “Fu-ck~!”

  As he finally ran dry, Julia released him with the utmost care, licking his entire cock clean before sitting back on her heels, swallowing one st time before pyfully holding her mouth open for him to see its emptiness.

  “Fuck. You girl has an incredible mouth..!”

  He dumbly blurted out, sitting down on the edge of the tub when his legs almost gave out on him.

  Julia’s eyes noticeably turned red, and she started to breathe harder.

  Suddenly, she lunged at him, grabbing his shoulder with both hands and straddling him.

  William grunted, feeling his back hit the wall.

  He looked at Julia, who seemed to have lost her sanity, breathing so hard - her breath clouded in the air - and looking at him like a predator gring at its prey.

  “Man!”

  Smack!

  A muffled sound occurred and Julia’s eyes rolled to the back of her head before slumping down, face against his chest.

  William, who could not react to how fast the situation changed, stared in shock at his younger sister, who was holding a metal rod.

  Did she just smack Julia’s head with that rod?

  Judging from the sound, it sounded like she hit her with all her strength.

  “This bitch!”

  “Gaak!”

  Celestina scowled in fury before grabbing Julia’s twitching bunny ears and swinging her whole body away.

  “I let you have a moment and you want to abuse it?”

  A scary look on her face.

  “Will, are you okay?!”

  William could hear Julia’s painful shriek as her body hit the nearby wall. He then looked at his sister who immediately started checking his body with a worried expression.

  “I’m fine,” William said.

  “You sure?” she asked worriedly, cupping his face with both hands and staring at him with - guilt and worry - combined.

  “Yeah. And you know, it’s touching me…”

  “What?” she let out a sigh of relief before tilting her head in confusion.

  William looks down.

  “Your cock sis, it’s touching me,” he said, teasing her.

  Celestina look dumbfounded before looking down, the pstic cock protruding from her strap-on was leaning against her brother’s cock, and her face turned red.

  “I, I’m sorry,” she said in shame before grabbing the pstic cock and breaking it off.

  William felt a cold air brushing his erection.

  Yup, my sister is wearing a tongue stud…

  William mused when he saw the tip of Celestina’s tongue.

  “But… are you sure she’s okay?” he gestured at the twitching body of the bunny who just got her head smacked hard by a metal rod, and her body thrown against the wall like a sack of rice. Is she even alive?

  Well, it seems she is, since she was now standing up.

  Like a zombie, she turned her head toward them, her eyes bright red. Though she didn’t seem to notice Celestina. Her eyes were strangely locked into him.

  “Man!” she was groaning very dangerously, drool dripping from her mouth like a broken faucet.

  Celestina’s grip on her brother’s hand tightened as Julia let out a soft shriek.

  Time seemed to slow as the girl unched herself toward him, moving with an unnatural speed and agility.

  But Celestina was ready.

  As she clicked her tongue in annoyance, she gred at Julia closing in, fist outstretched. Celestina met her charge head-on.

  The two collided in a blur of motion- Julia's fist connecting with Celestina's in a sickening thud. But Julia had anticipated the move. With a deft twist of her wrist, she grabbed Celestina's fist, using her momentum against her.

  Leaping upward, Julia sent Celestina flying backward, her lithe form tumbling gracefully through the air.

  William’s eyes widened as Julia kicked the wall, flying right at him. But his sister was fast. She immediately stood in front of him, intercepting Julia, grabbing the rabbit girl’s leg, and smming her down the floor.

  What the hell is going on?

  Was he transported in a fantasy novel?

  Are they going to cast magic or shoot beams?

  Thinking stupidly, William sat on the floor, watching in amazement, adrenaline coursing through his veins, as the two girls grappled on the ground, a tangle of limbs and curses.

  It didn’t st long, however, as Celestina managed to gain the upper hand, pinning Julia beneath her. Then without holding back, clenched her fist and punched the living daylights out of Julia.

  Julia shrieked in agony, but Celestina mercilessly pummeled her pretty face.

  After a while when she was not moving, Celestina stopped.

  She gred at Julia’s twitching body before standing up.

  “You okay?” she asked.

  William snapped out of his daze, nodding bnkly.

  What the hell did he just witness?!

  Celestina seemed to have misunderstood his expression - he was probably shocked and afraid.

  Fucking Julia, you just have to do that?!

  Celestina gritted her teeth, walking slowly toward William, not wanting to startle him.

  “Are you okay? Did she hurt you?”

  “I’m fine… though, again, is she okay? You didn’t kill her, right?” William smiled wryly, gesturing toward Julia whose face had turned bloody.

  Celestina snorted, “The fucker’s fine. Her body is sturdy. Don’t worry, I’m gonna kill that fucking rabbit ter.”

  “Ah, no, killing is bad.”

  William smiled wryly.

  “Or rather, is that really okay, you know, she’s your girlfriend, right?”

  Celestina looked at him for a moment before sighing.

  “Have you forgotten how strong and sturdy a mutant’s body is? You can break her bone and she’ll stand back up the next day,” she expined before reaching her hand on the sink, grabbing some tissue, she started wiping his face.

  She wiped the tissue across his face, her movements gentle yet efficient.

  She cleaned away the remnants of the intense act that had just transpired between him and Julia.

  William gazed at her, still trying to process everything that had happened.

  “Anyway, sorry about that.” she started. “The fucker must have been swallowed by her blood and lost her sanity. She’s not usually like that,”

  "Swallowed by her blood?" William repeated, brow furrowed.

  The phrase was vaguely familiar from his research, but he didn't fully grasp its meaning.

  Celestina grabbed another tissue and began carefully cleaning Julia's juices from William's member.

  He was surprised by the tender act but didn't stop her.

  She seemed to view it as a necessary task, like a devoted caregiver.

  "Yeah, you should know about that," she continued. "People with mutant genes tend to lose their reason. Their animal instincts take over. Though that rarely happens, unless they get stimuted so much their primal urges kick in hyperdrive."

  "Ah... yeah, I heard something about that," William acknowledged, still trying to get his head around what Celestina was describing.

  It made a sort of twisted sense, in light of how Julia had lost control.

  Her lust and aggression had taken complete hold until only base instincts remained.

  It was both terrifying and arousing to witness such raw, feral desire unleashed.

  "Forgive me…and forgive her, Will..." Celestina said again, her voice tinged with regret. "She doesn't usually let things go that far. But I guess you just proved too tempting for her."

  She finished her cleaning and tossed the soiled tissues away.

  William shifted, feeling strangely exposed yet oddly at ease under her care. There was a tenderness in her ministrations that he hadn't expected from his strange sister.

  “Well, I guess a part of the bme is on me…” he mused with a wry smile.

  Celestina looked at him for a moment, her expression unreadable.

  “... it’s her fault for being weak and unable to control herself,”

  William’s smile faded as he processed her words.

  "Are you not angry at me?" he asked, feeling a twinge of guilt.

  She looked at him weirdly. "Why would I get angry at you?"

  "...well, she’s your girlfriend, and I suddenly, you know, just went ahead and fuck her mouth," he said, the words tumbling out in a rush.

  Celestina's expression didn't change.

  "Why would I get angry at you for that?"

  “Well, for one, she’s your girlfriend?”

  Celestina looked at him weirdly.

  "It's not your fault that she couldn't resist you.”

  William was taken aback.

  He had expected anger, or at the very least, disappointment.

  But Celestina seemed unfazed.

  William could not understand his younger sister anymore. His gaze looks at her pretty face before looking down, seeing her budding chest, and the glistening metal stud on her nipples. Knowing it was rude and depraved, he desperately wanted to drag his gaze elsewhere.

  However, despite his reservations, he couldn't resist the temptation.

  If people in this world had no qualms about baring themselves to a man, then, surely it was okay for him to indulge in a little ogling.

  Another droplet of saliva went down his throat as his eyes nded on a cherry-colored nipple, causing his manhood to stir. Moving by instinct, his hands cupped Celestina’s chest while the tter was cleaning his thighs.
