Michelle followed the young redhead until the last bit of the girl's ass-length red hair disappeared into the girl's bathroom. Michelle slipped in behind her and used a janitor's key to lock the door. Michelle wasn't really a substitute teacher, but a hired assassin. She was being paid to take out the daughter of the Town Shariff, who busted the leader of a child pornography ring, while she was at school. It was a difficult job, but Michelle was very delighted at the challenge her new assignment presented. Michelle waited for the stall door to close and to hear the sound of piss hitting toilet water. Then she pulled the gun out of her panties and walked around the tiled wall and, much to her dismay, seen another girl coming out of one of the stalls. The girl, a 12-13 year old Asian with short black hair, didn't notice Michelle right away and kept walking, until she saw the gun in her hand. She stopped dead in her tracks and looked at the gun. "I'm really sorry you had to see this, I wasn't anticipating anyone else being in here. This is such an unnecessary waste," Michelle told her regretfully as she raised the pistol. Just as Michelle went to pull the trigger the Asian dived to the floor in panic, screaming; "Please don't kill me!" The bullet fired, but only struck the wall, kicking up a cloud of pulverized tile and concrete. At the same time she heard rustling before Cynthia threw open the stall door. She was clearly alarmed by the what was going on; her shorts and panties were around her ankles, leaving her smooth prepubescent cunt on display. "Wh-what's going on Mrs. Barrett? Cho?" Cynthia asked, puzzled as she looked from Michelle to the girl scuttling against the wall. Her eyes widened when Michelle pointed the gun at her. "I'm afraid I'm going to kill both of you." A cold smile appeared across her face as she said it. "You-you have to be joking, there's no way that gun is real." Cynthia mumbled, somewhat unsure of whether or not it really was a joke. "I-it's real, she-she just tried to kill me," the Asian, Cho, cried out. "You're not joking... Oh my God." Understanding filled her as her face distorted and tears started to flow from her eyes. "Why, oh God! Why? Please no." She staggered back against the toilet bowl and sat on the floor with her legs spread out, and her pussy on full display. "What would you want to kill me for?" "I don't, the person who hired me is the one who wants you dead," Michelle told her. "Why? I'm just a kid! I didn't do anything to anyone! I don't deserve to die!" She cried. "I know that you don't, and you probably deserve to die less than my usual victims. But innocent people die every day." "But we're just kids!" She restated. "I'm sorry, especially for your friend, since she's only going to die for going to the bathroom at the wrong time." "Wha-what do you mean?" Cho piped up. "I can't leave any witnesses." "Please-please just make an exception," Cynthia said, wiping tears from her eyes. "You-you can k-k-k-kill me, but let Cho go. She's really nice." Cho looked at Cynthia with gratitude, but then felt guilty of prospect of leaving her friend to die. "Please no... I... I..." "It's pointless to say that you can't leave her, because that isn't an option, you have seen me." Michelle interrupted. "But the school cameras have seen you," Cynthia replied, with a glimmer of hope. "You and I both know that the cameras aren't working at the moment." "But what about all of the students who have seen you?" Michelle responded by grabbing her brunette hair and pulling it, revealing dark brown hair underneath. "A-a wig, then..." Cynthia responded. "Then why does your friend have to die? Because my client will dock my pay if I don't kill any witnesses." Cynthia opened her mouth to respond, but before she could plea any further Michelle pointed the gun at the center of her forehead and pulled the trigger. Bang! Cho yelped as the bullet tore a hole between Cynthia's eyes and blood sprayed from the wound. Her head lolled back against the toilet, and blood trickled down the top of her head and into the toilet. Cho sobbed repeatedly and tried to beg; not for mercy or her life, but for this to be a bad dream. "I'm truly sorry," Michelle whispered as she pressed the barrel of the gun against the side of Cho's head. The Asian drew in breath one last sob as Michelle pulled the trigger. Her body shuttered as the bullet tore through her skull and sank into her brain matter. The crotch of her gym shorts turned dark and a puddle of piss started to pool around her pelvis. "What a waste," Michelle whispered to herself. She looked at the time on her phone, and realized that she still had twenty minutes before students were to be released into the hall; she wanted to do something that wasn't for money, but her own pleasure. Michelle put the gun back in her panties and grabbed the hem of Cho's gym shorts. She lifted the girl's legs and lower torso, and pulled both her shorts and panties off. She dropped the girl and threw the shorts into one of the toilets. Like Cynthia, her cunt was still bald. She lifted Cho again to remove her shirt; her breasts were already large for her age, but she wasn't wearing a bra. Michelle grabbed one of the preteen's breasts and squeezed it for a second, then turned her attention to Cynthia. She pulled the girl's blouse up over her head and tossed it to the side. She caressed the flat tween chest, feeling the undeveloped body beneath her gloves. Michelle lifted Cynthia's body and walked over to where Cho layed. She placed Cynthia on top of Cho in a vulgar position; with Cynthia's head resting on Cho's cunt and Cynthia's pussy on Cho's mouth. Michelle pulled out her phone again and snapped several images; both for pleasure and proof for her client. The girls were discovered fifteen minutes later when students rushed into the restroom after their class let out. By then Michelle was on her way out of town.
