Surprising sleepover

The day was great for Penelope. The gray mouse had just turned 15, and had planned months in advance to have a big sleepover with her friends. Her mom Jacqueline had okayed it and even bought Pen all the snacks and food she needed for her birthday-sleepover party with four of her friends. Everything was set up, the pizzas were ordered, and the guests were on their way for the party. Much to Pen's dismay, though, was that her younger white mouse sister Amy couldn't spend the night at her dad's house, so she'd have to participate in the sleepover as well. The young grey mouse sat on her bed, looking through a magazine as she waited for her friends to arrive. Being 15, she had already grown into her adult body, which was rather petite for a mouse. She barely stood 4'7" tall, and lacked the bust that most females attainted at her age, leaving her with a relatively small B cup. She still had nice hips, and as a boy once said, "a nice ass."
Penelope's ears perked as she heard the doorbell ring from her room. She hopped up and bounded down the stairs, but stopped when she saw the black fur of her mom answering the door. She stepped aside and let a shorter skunk into the house, who looked up the stairs and waved at Penelope.
"Hiya, Vivian!" the mouse chirped as she rushed down the rest of the stairs and gave the red-headed skunk a hug. Pen's mom took the gift Vivian brought over, as well as her sleeping bag and night bag. Vivian was the same age as Penelope, but her birthday was a few months before the mouse. The skunk was a bit luckier than her mouse friend when it came to body shape. She, like her mother, had developed early, having gained her mature body a year before. She had a decent bust, leveling out at a C cup, and the same curvy lower half her mother had. She was a bit taller than the mouse, standing at 5' tall, but she never commented on the size difference. The two rushed off into the front room to watch some TV while they awaited the other girls.
As time went on, Penelope's other friends arrived, with Kristi being the next. She was a cow but only in the literal sense of the word because she was very prudent about eating right. For being only 14, she was the bustiest of the group, dwarfing the others with a DD-cup bra, mainly because of her genes. She didn't have the udders her feral ancestors did, which was why her species' bust was so large. She was the largest of the group in most ways as well, standing 5'8" tall and having wide hips and what her friends called a "ghetto booty," all covered in short brown fur.
Terri the tigress eventually arrived, followed shortly by the vixen Bethany. Terri was the same age as Kristi, but was less developed than her cow friend. She stood a little taller than Penelope at 5'0", having had a bit more curve to her hips and butt than the mouse, but shared the same B cup. Bethany was the oldest of the bunch, being 16. She was also the second tallest, standing 3 inches smaller than Kristi at 5'5". She was known around school as a bit of a bombshell, having a D-cup bust and some womanly lower curves.
They all joined together to eat the pizza once it arrived, and soon afterward the birthday cake was cut and presents were opened. The girls retired to the front room to watch movies, laying out their sleeping bags and changing into their night wear. Penelope, Amy, Vivian and Terri all still wore pajamas, while Kristi and Bethany both wore nighties and panties. Jacqueline spent some time watching movies downstairs with the girls, but eventually got tired and headed back to her own room, giving both her daughters kisses goodnight before heading up to the second floor. As soon as Penelope was quite sure her mother was in bed, she sent her sister away, telling her she should go to bed, and that only the "older girls" could stay up. Amy, of course, pouted and tried to argue that she could stay up as well, but was eventually forced out of the front room.
In a huff from being sent away, the young mouse headed off towards the stairs leading to the second floor, only to detour and head downstairs to the basement, heading into her special corner. She had stacked various boxes together, making herself a small play-house near one of the window wells, padded the space down with blankets borrowed from across the house, and brought several of her stuffed animals down to keep her company when she played. She lay down in her box house, crying herself slowly to sleep as the girls upstairs continued their party. After an hour, a bright blue light began to shine down into the basement, illuminating the sleeping mouse. Amy rolled over slowly before she slowly faded away, disappearing from the basement as the light faded as well.
As Amy slept, she dreamed, having what may have been the oddest dream she had ever had. She awoke, inside her dream, somewhere unfamiliar. She was in a bright, featureless room, lying on her back on a warm metal table. She was slightly surprised by the fact that she was naked, but as she looked around she could find no one to look at her in her white-furred birthday suit. She was feeling very relaxed as she lay on the table, and even when she felt something pushing apart her legs, all she did was lie there. She squeaked softly as she felt something press up between her legs. It wasn't uncomfortable, so she didn't pay it any mind as it slowly slipped into her. She could almost feel it moving deep in her belly, and half expected it to come out her mouth before it stopped moving. She felt it sit there for a moment, before the arm began to pull out of her, leaving a small lump in her belly. She didn't feel anything more in her dream as it faded back into dreamless sleep.
Once more, the blue light illuminated the basement, lighting up the same patch of floor where Amy once slept. The little mouse faded back into view, still sleeping soundlessly on the basement floor as the blue light faded away. Amy slowly rolled onto her back, moaning softly in discomfort as her belly muscles began to contract around the lump in her belly. Her muscles pushed and guided the lump down her birth canal, and as it reached the entrance it began to pull itself out on its own. Its movement was impeded by the young mouse's panties, which the creature pulled aside as it crawled out of the mouse. It quickly fled from the vessel that brought it into the house, hiding out behind the furnace as it waited to attain its full size.
******
Upstairs, the girls had switched from watching movies to playing some board games. They had laid out a Twister mat, and all but Kristi, who sat off to the side, were playing. The cow was feeling sympathetic to Amy, who was also her friend, and the way the other girls drove her off. She stood up and excused herself for the moment, going to the stairs and heading to Amy's room. She stuck her head into the younger mouse's dark room, but didn't see the mouse in her bed. She shrugged and headed back downstairs to the front room, but stopped when she noticed the basement door had been left open. She went to close it, but heard something moving downstairs. Thinking it was Amy, she stepped onto the stairs, heading down into the basement.
"Amy? You down here?" she asked softly, looking around for the young mouse. She heard the movement again, a sort of shuffling sound coming from the back of the basement. She cautiously stepped further into the darkness, once more calling out to Amy, but once again only the darkness greeted her. She turned to leave, but felt something press down on her shoulder. She was startled for a second, but assumed it was Amy. "Ah, there you are. I wanted to see if you were all right," she said, reaching up to rest her hand on what she thought was Amy's hand. As her hand moved upward, she suddenly realized that the small mouse couldn't realistically touch her shoulder. She tentatively reached up to touch whatever was sitting on her shoulder, her hand trembling. Whatever it was, it wasn't any fur's hand. It was fleshy and hairless, and squished slightly as her fingers touched it. Her eyes snapped open in fear as the fleshy appendage wrapped slowly around her hand. She attempted to run, only to feel her feet get pulled out from under her as two tentacles wrapped around her ankles. Her one effort to scream was silenced before any noise left her mouth, a tentacle forcing its way past her lips, plugging her mouth as the others lifted her up off the ground. She could still not see what was assailing her, frightened whimpers emanating from her blocked mouth.
She felt other tentacles moving around her body, almost as if they were examining her. They slid under her nightie, stroking through her short fur. She began to struggle once she felt a single tentacle squirm into her tight panties, slithering across her rump and heading between her legs. Its flesh rubbed across her virgin sex, eliciting a muffled moan from the young cow. It continued to slowly stimulate Kristi's sex, even as a pair of smaller tentacles wrapped around her large breasts, squeezing them tightly and nudging her hard nipples with their tips. Kristi let out a muffled cry out as the tips of the tentacles around her breasts split open into four-jawed mouths, which covered her nipples and began to suck roughly on them. The cow's eyes went wide as the tentacle teasing her sex finally plunged into her, thrusting through her hymen and forcing its way deep into her....

The party continued on up on the first floor, oblivious to the happenings of the basement. The girls had traded Twister for Monopoly, and at that moment Vivian was ahead of the other girls. Terri looked around for a second, trying to find Kristi. "Hey, Pen...where'd Kristi go?" the tigress asked.
Pen gave her a shrug. "I don't know, probably went to go talk to my sister. Let's leave them alone and concentrate on our game, she'll come back in a few I suppose," she replied, handing the dice over to the tigress.
Terri was coming upon a gauntlet run...a bad roll and she'd end up bankrupt. She blew on the dice once, then made her roll, but soon flinched as the total came up. She moved her piece to its resting place, right on top of Park Place, which had a hotel that was owned by Vivian. Terri sighed and handed over her stuff; there was no way she'd be able to pay for the massive rent she owed. "All right, I'm out. I'll be right back, have to use the bathroom," she said as she stood up and headed into the hallway. She ignored the open basement door and ducked into the bathroom next to it, sitting on the toilet and doing her business.
As she finished and began to wash her paws, the door to the small bathroom crept open silently and a collection of tentacles snaked across the floor towards the tigress as she dried her paws. She turned around to face the group of green tentacles, gasping in surprise before she was swiftly gagged and restrained, the tentacles dragging the struggling tigress down into the basement. She bit down hard on the tentacle stuffed in her mouth, but it was ineffective, almost like biting rubber. Whatever the tentacles originated from was strong, her futile thrashing and struggling not ceasing until she was fully taken into the darkness of the basement.
Terri let out a muffled mewl, her ears picking up faint moans and sucking noises from someone else as more tentacles began to ensnare her, snaking into her pajamas and sliding across her fur. She felt the tentacles in her shirt open up and surround her nipples and parts of her breasts, the mouths suckling on her small breasts as a single tentacle wrapped up her leg, sliding up her pant leg and stroking across her sex. She mewled again as the thick head began to press open her tight sex, spreading her apart as it pushed against her muscles, which clamped down and tried to prevent the tentacle access. But the thick appendage was much stronger, and soon forced its way into her, breaking her hymen and pressing against the back of the girl's sex. Terri arched her back, her eyes centering on a spherical form silhouetted against the moonlight shining through the basement windows. The rounded figure was suspended by tentacles as well, but their midsections were vastly distended, jutting out into the air as the form slowly pulsed bigger and bigger. Two other orbs were outlined as well, seemingly being fed off of by two tentacles similar to the ones encasing Terri's own breasts.

The other girls were slowly winding down for the night, Vivian having come out on top after the Monopoly game. They put on one last movie to fall asleep to as they waited for the other girls to return.
"What do you think is taking Terri so long?" Beth said arbitrarily, lying on her stomach in her sleeping bag while watching the movie.
"Dunno...you think she fell in?" Vivian replied with a snicker, getting giggles out of the other two girls. Her stomach grumbled, prompting her to get up and find a snack. She headed out of the front room and thought the dinning room to get to the kitchen, completely missing both the open basement and the empty bathroom. She stuck her head into the fridge, looking through the groups of snacks set aside for them.
So engrossed in finding something to eat was she that she didn't notice the tentacles slithering across the kitchen tile towards her. She reached for a piece of cake that was stashed near the back of the fridge, but froze when she felt something wrap around her ankle. "Hey, what are y-," she started to say, but was silenced as something pushed its way into her mouth, having snaked up between her legs as she turned to see who was behind her. She let out a muffled cry as her legs were pulled out from under her, her body lifting into the air as more and more tentacles wrapped around her and dragged her off to the basement.
The basement was as dark as ever, the only light filtering in through the window well at the back of the room. Vivian could hear moans between the wet sucking noises that filled the room, even as the tentacles began to squirm into her own pajamas. The one in her mouth forced its way into her throat, causing her to gag before it pressed deeper. She let out a gurgled cry as she felt one of the tentacles snake into pajama pants waistband, stroking along her rump before moving between her legs. Her cry became a strangled moan as the head of the tentacle stroked across her sex through her panties until it pushed them aside and speared her sex, pressing through her hymen. She cried out in pain, her eyes tearing up as her virginity was taken, the tentacle pumping into and out of her sex in earnest. As the pain faded, pleasure began to mount inside of her, the thick appendage stretching her tight sex. She moaned again as two smaller tentacles ensnared her breasts, wrapping around them, and then encasing her nipples with their maws as they began to suckle.
She gasped as she was moved through the air, her side bumping into something round and fuzzy. She looked over and attempted to gasp, only to have a moan rumble from her congested mouth as she realized what she was pressing against. The black and orange striped fur was unmistakable...she was pressing against the distended belly of her friend Terri! She heard the young tigress moan softly as her greatly swollen belly continued to swell even larger, even surpassing the size of a bean bag chair. Vivian squealed out as she felt the tentacle in her sex press even deeper, breaking through her cervix and pressing into her womb. Her vision began to fade as she felt something began to fill up her womb.

Penelope was beginning to get annoyed. It had been over thirty minutes since Vivian had left for food, and none of the other girls had returned yet. She turned to Beth, thinking she knew what was going on. "All right, Beth, fess up...what's going on here? Did you all plan something ahead of time?" she asked accusingly.
Beth shook her head. "Ummm...as far as I know, nothing strange was planned for today, so don't look at me. Why don't you go and look for them?" she said defensively.
Penelope rolled her eyes, looking at the vixen with doubt. "Well...you're coming with me then," she replied, taking the vixen's hand and pulling her to her feet. Beth groaned tiredly as she was forced to follow her friend as they searched the second floor, then the first floor for their friends. They searched the kitchen last, not finding a trace of any of the other girls.
Beth sighed tiredly as the once again search through the kitchen. "Listen...let's just wait 'til morning. They'll give up on whatever they have planned when they realize we're not looking for them," Beth said in an irritated tone, then going quiet.
Penelope eventually looks up from searching under the kitchen table with a sigh. "You're probably right...let's head back to bed," she said, but paused as she turned to face the vixen, who was no longer there. She thought she saw the vixen's tail disappear though the door to the basement. She frowned and headed towards the door, assuming the other girls had taken her down to their hiding place. "So that's where you all are hiding, then..." She said to herself, hurrying over to the basement door and looking down. She didn't hear any footsteps, but they could have been moving really quietly. She crept slowly down the stairs, intending on grabbing the cord for the ceiling lights and exposing them all. She reached the bottom of the stairs and reached out blindly for the pull cord for the basement light. Her hand finally wrapped around the thin cord, and with a quick tug she illuminated the basement. She froze after her eyes adjusted to the light, the scene before her not what she was expecting at all.
Her friends and sister were each suspended into the air by a countless number of tentacles, but that wasn't all. Each one of them looked very pregnant! The mouse's eyes fell on her skunk friend, who had two thick tentacles messily thrusting in and out of her sex. The skunk was too incoherent to notice the mouse, her sex-addled brain only focused on suckling on the thick tentacle that slid in and out of her throat, which slowly fed her its cum. Her belly was a horrific sight, distended almost enough to carry litter of six full-term kits...and on a 15-year-old! The skunkette let out a low moan as her belly bulged even larger, two other tentacles feeding off of her now substantially larger breasts. Penelope was suddenly distracted as she heard the sound of tearing fabric. She turned her head and saw what it was.
Bethany was sitting suspended in the air just like the others, a tentacle in both her mouth and her sex as she was pumped full of semen. Her belly, while not as big as the others, had just torn through her thin nightie, bulging outward at a startling speed. The vixen's tail lashed back and forth behind her in agitation, her frightened eyes staring down at the mouse as two of the maw-tipped tentacles encased her breasts. Penelope suddenly snapped out of her trance-like state while staring at her vixen friend, but was too late to do anything as her legs were suddenly ensnared. She squeaked as she was hoisted into the air, but gagged as her open mouth was invaded by one of the tentacles. She groaned as she tried to struggle out of the grip of the tentacles, but stopped as she was lifted over near a strangely familiar striped sphere.
Pen attempted to gasp, but it was drowned out as the tentacle in her mouth spurted a salty substance down her throat. The slowly swelling sphere was that of Terri! The poor feline's belly was positively massive. She could hear the kitten's low mewls as her belly was pumped larger and larger, easily big enough to contain her former self and Penelope inside of it. She was temporarily drawn away from the tigress when she felt an unyielding pressure against her own nether lips, the tentacles forcing themselves past her sex lips and into her birth canal. She squeaked again in pain as it ruthlessly thrust through her virginity, and then pushed its way deep into her. She caught another huge bulge out of the corner of her eye, and could tell from the ruddy brown and white fur who it was.
The poor cow was the largest of the girls, easily big enough to secret a full grown feral cow inside her womb. Her tits were enormous as well, the tentacles suckling from her nipples hardly able to keep up with her flow. Penelope heard a muffled moo from Kristi, which joined her as she moaned, the first spurt of gallons soon flowing into her empty womb. The last thought that flitted through her mind before her mind was blacked-out by pleasure was the hope that somehow her mom would find and help them.

Jacqueline yawned, turning off her TV and looking over to her bedside clock. It was almost 4 AM, and she hadn't heard any sounds from the first floor, so she assumed her daughters and their friends had finally gone to sleep. She decided she'd check on them before she went to bed herself. She wrapped a silk robe around body, only having a bra and panties on underneath. She walked by both daughter's rooms, finding both doors open and both rooms empty. She surmised that even her youngest was sleeping downstairs with her big sister. She was quite surprised to find that the living room was vacant, the TV still running and the lights still on. She headed back to the stairs and noticed that not only that the basement door was open, but the light was on as well.
The black mouse stepped over to the door, calling down to the girls, but receiving no answer. She thought she heard some movement coming from down there, so she headed down the steps. The mother mouse was about to voice her annoyance at the fact that the girls were still up and playing around in the basement when she stopped in her tracks upon seeing the entirety of the basement. The writhing mass of tentacles seemed to ignore her presence for the moment, too involved with filling her daughters and their friends. She looked over to the stark white belly that used to be her youngest daughter. She wasn't the biggest by far, but was somewhere in the middle of Kristi's insurmountable belly, and her older sister's litter of four belly. She didn't care to try to understand why she was so small...perhaps it was her age that kept her exempt from the other girls' larger sizes.
Poor Terri was so bloated she had to be propped up onto her belly, which easily dwarfed her small body as she was continually filled. Vivian was fairly large now as well, her overstuffed belly nearly as big as she was. Bethany was seated upright, held erect by the tentacles as they bounced her up and down. Her belly jiggled as she moved, jumping up and causing her now huge breasts to audibly slosh and shake as they were milked.
Consumed by fear, Jacqueline eventually focused on the crowd of tentacles that began to slither towards her, worming around the banister and wrapping about her body. There was no way she could escape regardless, so she gave herself willingly to the creature.
Her robe fell limply from her body as the tentacles ensnared her limbs, her bra snapped off and panties pushed aside as the tentacles began to take their last victim. She moaned loudly, her mouth quickly filled with an already cum-covered tentacle, her mouth suckling the salty fluid from the tip as her breasts were engulfed by the tentacle-jaws. She felt a sudden pressure deep in her belly, and soon her womb was stuffed full of tentacle and cum, the tip of that shaft pressing to the very back of her womb as it began to spurt its load into her. She could feel her breasts begin to expand against the suckling tentacles, the long-dormant milk ducts suddenly switching to full production as they filled with milk. Her belly soon felt just as full as when she was pregnant with Amy, but that soon passed as she was stuffed more and more with the alien creature's cum. She let out a stifled moan through the tentacle invading her mouth as her sex clamped down onto the thick shaft that filled it, her first of many climaxes coursing through her body. Her last coherent thought was about the eerie blue light that suddenly shone through the window as the last of her rational mind was overwhelmed by pleasure.
The alien ship above quickly removed its creature and its seven victims, soon darting away and out of the atmosphere as the sun began to rise, leaving the house devoid of all life.
The aliens were quite pleased with their new breeders.
The End
