Amanda was a beautiful girl of 17 with a nice athletic body, long red hair, nice round face, shaved pussy, and a pair of small firm breasts with puffy nipples. Jessica, her 12-year-old half-sister, was just as gorgeous. She had a nice slender frame, long legs, jet-black hair which fell to her ankles, and a dark complexion thanks to her Latina mother. Both girls had an unusual relationship. Since both of their mothers had passed away(Amanda's from a heart attack, and Jessica's from a car crash, so their father had said) and their father was usually busy, Amanda took care of Jessica most of the time. For three years, however, the relationship between the two girls became more intimate. Amanda had been looking at lesbian porn on the Internet when her sister walked in, one question led to another and somehow Jessica talked her sister into eating out her pussy. Before long they were having sex with each other on a regular basis. That Saturday the two girls were alone, their father was away for the next two weeks as usual. The girls really didn't mind it as it gave them more time to bond. Amanda never had any problems out of her sister and not having a nosy parent around meant she normally had plenty of freedom. At 10 PM Jessica emerged from the shower and went into the bedroom, still completely naked. She layed on the bed next to her sister, who was also bare. When there father was away the girls never put on any clothes unless they had to go somewhere. Jessica rolled over and Amanda embraced the preteen in her arms. The cuddled next to each other, Amanda enjoying her sisters wet naked body, before locking their lips and kissing each other deeply. They kissed and licked tongues for several minutes, then Jessica asked the question. "So... do you want to make out before we go to sleep?" Jessica asked her sister, sticking a finger in Amanda's pussy as she did so. "Sure. Why not?" Amanda replied. Jessica crawled on top of her sister and started kissing her neck mouth before making her way down to her tits. Amanda's nipples were already hard when Jessica's soft tongue started to softly caress then. She started sucking and gently biting on them causing Amanda to sigh is pleasure. Jessica continued sucking on her sister's tits for five minutes before deciding it was her turn, at which point Amanda thought she was going to have an orgasm from that alone. The two girls switched places and Amanda started sucking on Jessica's budding tits. Jessica was in a fit of ecstasy within a minute and three minutes later she was having an orgasm. Robert parked his car several miles down the road and made his way towards the home of Amanda and Jessica. Unknown to the girls their father had pissed off Robert's client and now that client wanted to send a very clear message. As he made his way towards the house he noticed that the gate leading to the property wasn't even locked. He swung it open and walked up the dirt road leading to the house. Amanda was on her back with her legs spread and her sister laying on top of her. Jessica was laying with her head wrapped around her sister's head while her own head was between Amanda's legs. Slowly Amanda started to lick around Jessica's pussy lips, Jessica meanwhile already had her tongue down Amanda's hole. Both girls were panting heavily and moaning. Jessica shoved two fingers up her sister's asshole while continuing to lick her pussy. Robert approached the door and pulled out the key. His boss managed to acquire it from girls' father so he wouldn't have to pick the lock. He turned the knob slowly and crept in. As soon as he crossed the threshold and quietly shut the door he could hear the moaning coming from their bedroom. He pulled out a 44 magnum and slowly made his way to the victims. Normally he wouldn't carry a loud weapon, but the client asked for their deaths to be a little messier than usual. Luckily the area was out in the country, so anyone who did hear it wouldn't be at all surprised to hear gunfire. He looked around a narrow hallway, their bedroom was at the end. The door was wide open and the girls were in full view from his location. He couldn't help being fascinated by the scene that was before him, he felt an erection growing in his pants. He noticed a small stand half way down the hall and quickly made his way to it, not being noticed at all by the two sisters. He looked around the side and aimed his gun at the top of Jessica's head When Robert entered the house the two girls were already close to cumming. Amanda's tongue was now licking away at Jessica's wet pussy and she was using three fingers to massage the labia. Jessica was still licking away at her sister's pussy and now had five fingers jammed into her sister's ass. Amanda's moaning intensified as an orgasm enveloped her. Jessica continued licking away as her sister's pulsating pussy started squirting pussy juice into her mouth and onto her face, Jessica made sure to get as much as possible before smaking her lips and saying, "yum". A few seconds later Jessica started to cum and as she did so she lifted her head and arced her back as bliss filled her every being. In the few seconds it took for her to raise her head and back she heard a loud bang and her sister's cunt exploded into a fountain of blood. She barely begun to register what had happened when Amanda jerked up, sending Jessica to the floor sprawling, and started screaming. Jessica watched helplessly as a man entered the room weilding a gun. Amanda was still crying in agony when he grabbed her by the arms, pressed the gun against the girl's left breast, and fired. The bullet went through her lung and left a huge gaping hole on the other side. Amanda coughed up blood and sputtered for about twenty seconds before going limp. The man left Amanda lying on the bed drenched with her blood and walked over to Jessica. The girl was already crying with hands over her face, as the man approached closer she looked at him. "Why? -sob- Why did you h-hurt my sister?" She cried, leaning back with her arms out in front of her. Robert said nothing as he walked closer. "Are... are you going to kill... me... too?" She asked, tears still coming down her eyes. Robert looked at her for a moment, he felt pity in his stomach. He also felt something else below his stomach while staring at the pretty little girl whose life he was about to end. "Yes," he replied, "I am going to kill you." "Can you please not make it hurt?" She asked, still thinking of how much her sister screamed when her pussy got shot. "I promise that if you don't struggle or try to resist I will put the gun in your mouth and shoot you through the back of the head. It will be very quick and you won't feel a thing," he told her. "I won't struggle," she replied as fear and dread washed over her like a sickness. It only grew worse as the man raised his gun and brought it closer to her mouth, but then something caught her attention. "Is that your penis?" She asked the man, pointing at the buldge in his pants. She didn't know why she said it, probably hoping to delay the inevitable, though there was a little bit of geniune curiosity in the question. "My... my, what?" He replied, slightly taken by surprise. "No, it's just a buldge," he lied. "No, it's your penis," she said, showing more curiosity this time. "I seen them in porn. My sister said that it means a man likes a girl," she continued. Robert was still in shock, but that was quickly fading away as he reminded himself that she was licking her sister's pussy just a few minutes ago. "Can you let me see it before you kill me? I have never seen one in real life?" She asked him. He didn't have to think long before he unzipped his pants and pulled out his huge cock. She looked at for a moment with both curiosity and wonder. Before he could stop her she grasped it with her right hand and started caressing the tip with her tongue. At first, he didn't want her to keep going, but then he really enjoyed her tongue on his dick. Until now he never thought he would see a preteen girl this way. "Do you like it?" He asked her. "Yes, I think so," she replied. "Listen," he said, "I will let you live long enough to suck on my dick, but you have to swallow as much as possible when I cum. Also, if you bite me or try to grab my gun, I will make sure you suffer a lot before you die." Jessica simply nods in agreement to every word he said before returning to his cock. She continued licking on the head for a few seconds before stuffing it into her mouth. She sucked on it, moving her mouth up and down his shaft with increasing speed, while her tongue was busy probing every inch of it with her tongue. She cupped his balls in her hand and started softly caressing them, as she had seen girls do in all of those porn videos. Robert thought to himself that she was doing quite well for such a young age, especially considering that it was her first time giving a blowjob. She sucked dick better than many adult women he had been with, and that was saying a lot. With his left hand he started caressing the side of her face and hair. She was now taking almost the whole length of his cock down her throat with each thrust, gagging a few times. Before he knew it he was cumming in her mouth. At first the girl was surprised and a little bit of his seed flowed out and down her chin, but she was still able to take most of it down her throat. After he pulled his cock out of her mouth she licked the cum off of her lips and started cleaning his cock. She knew that the longer she kept pleasing him the longer she got to live, he sensed it so he grabbed her right shoulder. "I'll give you ten more seconds to finish cleaning my dick," he said. With that the sense of dread reared up into her again, tears started to form in her eyes. Despite that, she made sure to lick as fast as she could, wanting to enjoy every last drop. At last her ten seconds were up and he made her stop, his dick was already mostly cleaned anyways. "I'm sorry, but if I don't do this not only do I not get paid, but I lose my own life," Robert said. Jessica closed her eyes and let the tears flow down her face as he aimed his gun. She soon felt the cold metal pressing up against her lips, she opened her mouth to let the man push it in. She soon felt it reach the back of her throat, the cold metal left a bitter taste on her tongue that was nothing like the delicious treat she just had. He pulled the trigger and all thoughts ceased as the back of her head was blown out, brain tissue and blood splattered on the wall behind her as she dropped to the floor. Robert started to leave, but looking at Jessica's dead pussy spread out on the floor made him realize that he was not fully satisfied. He got down on all fours and rammed his cock into her spread out cunt, he could still feel her body twitching as he fucked her. Robert knew then that fucking a dead girl was thousands of times hotter than a live one, the idea kicked his lust into overdrive as he pounded away at her lifeless cunt. By the time he got up and put his cock back into his pants an hour had past and the girl had rivers of blood flowing out of her pussy. After finishing up Robert got some cleaning supplies and made sure to clean up as much cum as possible, not wanting to leave behind any evidence. He then took a few images(some for his boss and some for himself) before giving both girls a good-bye kiss on the nipples and leaving. Their father would find their dead bodies two weeks later, he ended up committing suicide minutes after finding them. Their bodies were not discovered by authorities for six months.
