"Watch were you're aiming that thing!"

The sound of Osako's voice filled the room, earning a scoff from the vampire as she pointed the barrel against her skull, as Fyodorova laughed in the background. "Seems like she's learned from her mistake now. Goodbye, Dazai." Before her voice cuts out, leaving the two girls alone. 

The smooth barrel presses against Osako's head, and she arches from the contact of it, staring up at Chizuru. The pain in her leg, blood rushing from the first attempt— today was not her day, it seemed, because this meant she was going to lose to Fyodorova, and to top it off, Chizuru was going to deliver her execution. She had dreamt about this many times, except the roles were always reserved—

Chizuru with a gun to her head, looking like a frightened rabbit. She pulled off the deer in headlights amazingly, blue eyes so big and round and wet with tears as Osako lowered the gun, sliding it into her mouth, over her tongue. 

"Relax," Chizuru's voice reminds her that she's human, glued on fangs and red contacts hiding the lust in her eyes. "It won't hurt you." She mumbles, but there's an edge to her words that says maybe, allowing a shiver to crawl up Osako's spine. 

A smirk stretches on her lips, nudging her hips forward. "Oh really?" She can't help but tease, knowing that they can have as much as they want without Fyodorova finding out their plan, well, until Chizuru has to wander off and report the news. "Fuck off. I wish I could kill you." Chizuru breathed, not wanting to think about the wet spot forming on Osako's panties, or her own. 

"And maybe you can," Osako cocks her head, her gaze piercing the pistol. "We can do other things with it, too." 

"You're insane." And that was the whole point of their plan, toying around with sick thrills. 

Chizuru tried not to look at what she was doing, but she had to, her narrowed eyes focusing on the sight of the gun between Osako's thighs, rubbing over the fabric. "You're an actual freak if you're getting off on this," however her words couldn't hide her ragged breath.  

"Aww, shut up, Chizuchin! You know you're loving this as much as I do!" Her ex-partner chirped,  earning a scoff from the ginger as her hand gripped the pistol, fingers wrapped around the steel of it and giving the woman a disgusted look each time she heard her breath hitch, hips rutting into the firearm. "Doesn't it feel good to put me in my place?' She asked with a grin, and Chizuru had to roll her eyes again. 

To be frank, she always imagined it like this: Osako spread open, her face contorted in sick pleasure as the pistol fucked in and out of her, soaking the steel gun in her juices, her cunt swollen and red. Completely at her mercy. 

The thought excited her more than she would like to admit. 

"Come on, stick it in already," Osako laughed, her eyes glazed over with need. This was disgusting, and Chizuru hated every second of it, knowing she would ultimately have to give in so she wouldn't waste time. She was as sick as her. 

Slowly, the pistol slid underneath Osako's panties. The brunette tensed from the contact, arching her back again and whining from the sensation of cold metal pressed to her folds, gliding between her wetness to tease her. "Fuck you..." She panted, shutting her eyes. "Just slide it in, break me in with the gun."

And a smirk couldn't help but creep on her lips, relaxing in the role that Osako seemed to cream over, ignoring her arousal and just focusing on how wonderful this feels, as Chizuru slowly but surely shoves the barrel into her cunt, earning a moan from her frenemy's lips. "There's something seriously wrong with you," she comments, feeling how tight she is around the pistol.

"C'mon, then." Osako said, sweat sticking to her forehead. The metal felt so raw inside her, her insides tugging to the intrusion. A gun is the perfect shaft, always standing hard and never once going soft, much more desirable than a cock. The thought of it going off is rather intangible the threat of pregnancy, and Chizuru froze, knowing what she wanted to do to her. "Rip me apart, and tear me open." She giggled like a child with blood in her hair. 

"Fine then!" Chizuru gave in completely, losing her inhibitions as she leaned forward to dig her teeth into her shoulder, wishing the fangs were real— wanted to draw blood, wanted it to fill her mouth. She was driven by instinct, remembering all the fantasies that led her to this moment— Osako Dazai with a gun up her cunt, losing herself to the disease threatening to eat her whole. 

Not before Chizuru did, she smiled. 

"You're a slut," she spat on her, causing another whimper to fall from Osako's lips, the gun fucking in and out of her, filling the room with a squelching sound that made the mafioso weak to her knees. "And you're the one using me. What does that make you?" She asked with too many teeth, earning Chizuru to press her foot down on her mound. 

"Ah- fuck!" The suicidal woman screamed from the contact of her shoe pressing down on her (belonging to some name brand that Osako was too careless to know about), squirming. "That hurts, Chizuchin!" 

"Yeah, whatever, you wanted it, whore," her words dripped with malice that shook Osako to her core, and the hypnotized eyes she was wearing wasn't helping it. Chizuru bared her teeth, thrusting the pistol into her willing victim before pulling it out and shoving it deep in Osako's mouth, catching her off guard before eagerly taking it, looking so fucked out. The lengths a masochist would go to be brutalized was beyond her, but she was willing to throw the dog a bone. 

"M-mhm, fuck yeah I did!" 

And so, Chizuru brought her boot down, giving the detective a kick to her cunt. Another scream ripped from Osako's lips, albeit muffled from sucking on the firearm like a cock. Her tongue swirled around the steel, coating it in her saliva as she lapped up her own taste on it. "Fuuuck," she whined. "Thatshithurts-"

Chizuru tortured her cunt in glee, kicking it after kick. By now, Osako's pussy was swollen and bruised, shivering in delight as Chizuru pressed down on her clit, her eyes glued to the sight of the sensation overwhelming her until she came. "Stupid slut."
