*****

It was a beautiful day at the Sudbury Household. 20 year old daughter Sarah was lying in bed. She was watching horror movies on her iPad. Her mom Alexa was out shopping for groceries. Her younger sister, 18 year old Sabrina, was out with her friends. Finally her older sister, 36 year old Amanda, was in college. As for Sarah's dad, he passed away a long time ago, when Sabrina was 4 years old.

Their dad had been having heart problems for many years. One day, he was waking up in the morning, sat up and then collapsed on the bed. His wife Alexa called the nearby hospital and they rushed him off to the ER room.

Sarah shook her head and continued to watch the movie, listening to the audio using her brand new AirPods that her mother had gotten her for her 18th birthday. She was all alone in the house.

She was watching the movie, when the video froze. She tapped the screen and it did nothing. "Lousy, fucking IPad," she cursed. "My mom is so cheap. She had to buy this item from that Discount website, instead of getting a brand, new one." She was unaware that the IPad she was using was infected by a demonic entity.

"Useless piece of discounted rate shit," she said as she threw her iPad onto the front of the bed. Suddenly, the IPad turned on and a distorted image appeared on the screen.

"Hello young one," a demonic voice said. "You are a dirty little girl aren't you? Thinking about your sisters and mother in dirty little thoughts."

"Who are you?" Sarah replied as she looked around her bedroom. The unknown voice chuckled and began to continue.

"Come now Sarah," the voice said. "Do you really think I will tell you who I am?"

"How the fuck do you know who I am?" Sarah shouted, standing up and glaring around her bedroom.

"Oh Sarah," the voice replied. "I know everything about you. I know that you are completely alone, after that jerk of a boyfriend Tim dumped you. I know that you go to bars, trying to pick up to guys, but secretly you are nothing but a little, incestuous, lezzie slut. I know that you fantasize about your little sister Sabrina, climbing into your bed, spreading your legs and eating your sweet, little pussy. And I know that you dream of fucking your sisters with a strap-on while your mother videotapes everything."

Sarah was lost in her own thoughts. How could this creature thing know all this? Had it been spying on her since she was first in her bedroom. She sighed deeply and spoke. "What is it that you want from me?"

"All in good time my dear Sarah," the voice said. "First things first, I notice that you are wearing your PJs. Could you please take them off slowly?"

Sarah was speechless. This thing wanted her to strip naked for it. She slowly removed her PJs, first her top then her bottom. She was now fully naked lying on her bed.

"Such a beautiful body Sarah," the voice said. "Now I am sure you want to touch yourself and make yourself cum, but first my friend wants to have some fun with you."

Sarah paused and her eyes widened as she saw what looked like Samara Morgan from the Ring. The entity removed her own gown, revealing her big, thick cock. Sarah didn't think that big cock was going to fit inside any of her holes. However, Sarah didn't know that the entity's cock was currently falacid.

"Now then," the voice said. "Why don't you show her how much you want her cock? Sarah was lost in her own thoughts. Her mind was telling her not to do this, but her body was interested in it. As if she was under a spell, Sarah crawled over to the entity, grabbed the cock, and stuck it inside her mouth.

"What a slutty little girl you are Sarah," the voice said. "You are enjoying yourself very much. Just keep sucking, Just keep sucking, Just keep sucking, Don't you fucking stop sucking."

Sarah, having her own mind completely unable to stop her, continued her sucking. She bobbed her head up and down on the cock.

The entity was very aroused. It had blowjobs from many different girls in different places. The entity placed it's hands on Sarah's head and sent a mental image to her.

Sarah, as her face was fucked, was shown images, dirty images of the entity fucking different girls in different places. The image that Sarah was shown was an image of a schoolgirl in the girls bathroom inside one of the stalls. Behind her, the entity was holding her hips tightly, as it assfucked the schoolgirl against the stall door. This image pushed the entity over the edge and it came inside Sarah's mouth.

"Schools make excellent breeding grounds," said the voice. "They're easy to get into and have lots of girls. Not just the students, the adult females as well. Teachers, coaches, janitors, sometimes even a principal or dean. But she's opportunistic. She will breed anywhere she's likely to find a girl or woman alone and vulnerable. Waitresses on the closing shift, dark alleys off empty city streets late at night, lone riders on a late night subway car, squatters in abandoned buildings. And away from cities there are hiking trails, secluded beaches, and farmer's daughters out venturing in their fields. Just to name a few."

"Sounds like she moves around quite a bit," Sarah said, after swallowing down the cum.

"Can't stay in one place too long," explained the entity, who finally speaks. "The girls don't talk, but I can't chance that. Have enough of them in the same area and sooner or later people might start noticing something. Better to make a few scores then drift off to somewhere else and remain unknown. And I enjoy seeing new scenery."

"And making yourself look human, that helps you get close to unsuspecting potential victims, no doubt," Sarah said.

"It depends on the situation, it's not always necessary, but yes, that's right. Plus changing into a monster right in front of their eyes adds a bit of a dramatic flair that can heighten the initial fear response," the entity said.

"Quite the devious creature, aren't you," said Sarah with more disdain than respect. Even with her hands separating them, Sarah's skin was crawling just being in the room with the entity. She had to get out, but one last question sprang to mind.

"How young of a girl do you..." her voice faltered, she was afraid the answer might make her sick to her stomach.

"Do I go after?" the demon finished. "You know it wasn't all that long ago that girls were married off and started having children as soon as they reached the age of 18. Have I taken girls that young? Most certainly. But I do prefer them a bit more grown. university age, in modern terms."

Sarah was lost in her own thoughts as the entity left her in the bedroom. She had no idea what was going to happen next. Soon the entity returned to the bedroom, but she was not alone.

"Did you miss me?" She heard a voice... well, not quite heard, and it wasn't exactly a voice as she'd normally define it, but the words were clear. Miss... oh. Oh, no, it couldn't be. She hadn't seen the monster under her bed since she was what, eight? Nine, the last time must have been when she was nine years old. How could it be back now, eleven years later?

"I've waited a long, long time for this," the voice said, somewhere between smirking and sneering. Sarah felt a tentacle wrap around her right ankle. She then felt another tentacle wrap around her left ankle, holding her down to the bed. Before she could reach down to try to free herself, another two came up from either side, grabbing her wrists and pulling them down. Sarah lay spread-eagle, unable to move or speak, and hardly even able to see in the dark. She was confused by the monster's words, though she shivered again, from fear instead of cold, when she felt yet another appendage drag along her knee and up her thigh. Waited a long time for... Sarah was revolted by the thought of it waiting there, lying under her bed, pondering what it would do as it watched her grow up.

The tentacle soon reached her panties and pulled them down, ripping them off and tossing them aside. "Oh no, no, no..." she tried to say, though she was still muffled by the tentacle across her mouth. It slid along her slit, coating her with its juices, and she couldn't help but shake when it touched her clit.

"Oh yes..." the monster said from somewhere, its tentacle pressing against her lips, pushing inside her folds. She groaned in horror at the feeling, this couldn't be happening. This must be some crazy dream, how could her imagination from when she was just a tiny girl be back to torment her now? It was impossible. And yet, impossible or not, she realized the tentacle was deeper inside her, filling her more completely than anything ever had before. Sarah wasn't a virgin by any means, but this felt entirely different, this was... she wasn't sure what it was, she was horrified, but it was definitely something new.

At the same time, the tentacle across her face seemed to change its mind, shifting to press into her mouth. Sarah had little choice, her mouth had already been stuck open, and she doubted she could prevent it from entering anyway. She did her best to shut herself away in her mind and not pay attention to what was happening to her body, so that she didn't even notice her bra being tossed aside. She was even able to ignore the tentacle inside her starting to pump itself in and out slowly, but her concentration was broken when the tips of two more tentacles flicked her nipples. Her back arched with the sensation, and despite herself, she realized that not all the juice in her pussy was coming from the monster.

With an emotion somewhere between resignation and curiosity, she flicked her tongue against the tentacle in her mouth. She was too afraid that biting it would just get her in a worse situation, and it was... surprisingly sweet? Actually, it didn't taste all that bad. She began to lick at it slowly, dragging her tongue along the appendage, and was surprised to feel the monster seem to respond, the tentacles holding her shaking slightly. The one inside her began to move more quickly, sliding in and out, completely filling her every time it pressed in. Sarah moaned again, this time in pleasure, as she felt yet another tentacle tickle her clit. The combination of a filled mouth, her breasts and nipples being played with, her cunt being filled and her clit being gently stroked was too much, and the girl began to enjoy herself, even as her mind protested that no, this was too horrible, how could she be getting off on it?

The four tentacles holding her arms and legs lifted her into the air, holding her body completely off the bed. Finally just giving up and giving in, she began to move her mouth back and forth, sucking and licking the flesh in her mouth. She was beyond the point of worrying about the fact that none of this was possible, and now wrestling with the fact that disgusting as it was, she could feel an orgasm building. The tentacle in her mouth reacted to the extra attention and began to press in and out of her lips even as she dragged her tongue along it, and she felt the ones attacking her pussy and clit speed up. Her body began to shake, back arching, hips thrusting back against the intrusion as much as possible. Sarah was about to cry out in orgasm when something stopped her build.

Oh, no.

The tentacle inside her mouth squirmed it's way through her esophagus. Before long, the tentacle reached the end of Sarah's ass, where there was a buttplug. "Nice try Sarah," the voice said. "But that's not going to stop us." With one last push, the tentacle popped out of Sarah's ass holding the buttplug and threw it onto the floor.

She tried to scream and protest as she felt something else wet against her ass, but the tentacle pummeling her mouth muffled her. Even as she stopped reacting to the monster's attention, it kept pumping into her, rubbing her clit and nipples, as the new tentacle poked tentatively at her asshole. It paused, as if the monster were debating, and then suddenly surged into her, filling her as deeply as it could all in one go. She couldn't help but cry in pain, even with her mouth full, and any pleasure she felt was cut off by the sudden thrust. The new tentacle surged through her body, until it popped out of her mouth.

Still, disgusted as she was, she was helpless to do anything about it. The monster had her body completely restrained as it continued to use her, simultaneously thrusting into her pussy, mouth and ass as well as playing with her clit and nipples. She noticed the tentacle inside her pussy start to shake, and felt sick when she felt something warm and sticky spray inside her. Before she could think about it too hard, she realized it had retreated and been replaced by a fresh one, slamming into her just as hard. The one in her ass started slow, sliding in and out, but began to speed up. She felt like her body would fly into the ceiling from the force if there wasn't something just as powerful pushing her down. And then again, to her revulsion, she realized she was reacting, her tongue and mouth had begun to pleasure the tentacle again without her even noticing, her hips were bucking, and her clit was spending sparks throughout her body. Even the assault on her ass was beginning to feel pleasurable, she was filled like she never had been before, and EVERY sensitive area of her body was stimulated all at once. Suddenly, the tentacles that held her wrists and ankles wrapped tightly around them. Both of her wrists were bound by two tentacles, just like her ankles. She was held above her bed, about 6 feet high. The demonic entity smiled and began to leave. "Have fun Sarah," it said as it left Sarah in her own pleasure.

Fortunately or unfortunately, this attention didn't take long to build her orgasm. She lost track of time as she sucked greedily, even swallowing when the monster came into her mouth, only to be presented with a new tentacle to fellate right away. Sarah herself came next, groaning, crying and moaning around the fleshy appendage, her entire body bucking and writhing as much as she was able to move.

After her first orgasm, she could hardly remember the rest of the night. How many tentacles fucked her pussy, her mouth, her ass? How many orgasms did she have? How many loads of monster cum filled her body before it finally left her alone? The girl had no idea. After what seemed an eternity, the monster was done, its uncountable tentacles all having emptied themselves into the helpless girl (two had even cum on her tits, not that she had been able to notice.) The monster set her back down on the bed, retreating back to its home underneath.

"Good night, Sarah. See you again soon..." it said, somewhere between menacing and amused.

Shaking, though she wasn't even sure what she was shaking from anymore, Sarah curled up under the blanket again, holding herself as she tried to fall asleep. She was too exhausted to even clean herself off first. And the worst part was... she wasn't sure she wasn't looking forward to the next night... She suddenly got on all fours and began to puke and shit out cum. After a while, Sarah laid back on her bed, which was covered in her own juices from the fuck. Her eyes were glazed over, like she was under a spell.

"You are a lot of fun," the voice said. "Now it's time to share it with your sister Sabrina. Wouldn't you agree?"

"Yes I would," Sarah said. She stood up and began to walk over to her sister's room.
