(sigh) I guethh I'm a thlut, now...
The wedding ceremony was simple, but elegant. Twist sat in the front row of the chapel and cried the appropriate amount of tears as her mother and her new husband stood before the minister and exchanged their vows, and then got up and hugged her once the "I do's!" were finished. She then stared up and up at her new "Dad." He would never, ever replace the father who had passed away less than a year ago, but there was no denying he was...interesting.
Maybe too interesting...
As she still had some time before she left Ponyville for college, Twist had decided to stay in her parents' home for the duration...and then, tragedy struck. She and her mother had spent the first months weeping together over her father's untimely passing until one day her mother had dried her tears, taken off her mourning clothes, and started dating again. Her daughter kept her thoughts to herself, but Harmony could tell from the looks she sometimes gave her that Twist did not approve of her mother...moving on...so quickly.
Until she was introduced to a stallion named Stoney.
Right from the start, the new stallion had Twist's undivided attention, although she did her best to keep any...attraction...she felt to herself. Still, her mother always had good taste in stallions, and though she would never, ever think of him as her Dad...she couldn't deny he...might not be so bad to be around!
That was...until a few short weeks later...and the night he'd sat her and her mother down and explained the new...rules.
She'd had some inkling of his disapproval of her long before this meeting, as he'd been giving her unexplained frowns at mealtimes, or had paused to watch her briefly whenever he'd entered the living room and seen her spending hours playing video games. On one of those occasions, she'd looked up at him and asked, "Ith thomthing wrongth?" but he hadn't answered; he'd simply shaken his head and left the room.
So now, as the three of them sat at the dining table one evening, she wasn't that surprised when he stared directly at her and began.
"Why aren't you working a job?" he'd growled, as he gave her a stern look. He flicked his gaze at her mother then added, "All I've seen you do for the past few weeks is play video games, talk to your friends, eat, and sleep."
Twist's eyes grew wide behind her glasses, and she exchanged a glance with her mother before replying, "Because I've never had thoo...Mom and Dad alwayth thook care ofth me..." He frowned.
"Well, sorry to inform you, young filly, but that changes as of now. Everypony in this house needs to pull their weight, in one way or another. Life doesn't grant us 'free rides.'"
Twist stared at him, then jumped to her feet. "How dare you thpeak to me like thath! You're noth my father! I don'th have to lithen to anything you thay!" Stoney stood as well.
"This is MY house now, so you WILL listen to me!" Twist rounded on her mother.
"Mom! THAY thomthing! Don'th leth him bothh me around!" But her mother looked away and blushed.
"He's right, Twist...you have to listen to him." She met her daughter's eyes briefly, then turned away again. "Your father is gone, honey."
Twist placed her hands on her wide hips and faced him squarely. "Thith ith BULLTHIT! I'm noth a little filly anymore!" And with that, she spun on her heel and fled, before he could see her tears. Making it to her room, she slammed the door as hard as she could, then fell onto her bed. It just wasn't fair! WHY would her Mom marry such a jerk?! Then, she directed some of her anger towards herself. How could she think he was handsome?! It didn't matter what he looked like, he's a complete DICK!
Just then, there was a knock on her door. "Go away!" she cried, "I don'th wanth to thalk to you, Mom!" But to her surprise, the door opened, and it wasn't her mother. Twist sat up and angrily faced him. "Whath do you wanth?! I haveth nothing to thay to you!"
Stoney shut the door, then calmly took one of her chairs and sat close to her bed. "That's fine; you can simply listen." He leaned forward, as she drew back. "I told you there are no 'free rides' in life, and that everypony needs to pull their weight." He smiled, and then stood and began unbuckling his belt. "If you do not wish to get a job outside this house, I can think of a way you can be useful inside it..."
Twist sat frozen, her eyes wide behind her glasses as she watched him completely undress, and then she gasped as his massive cock was revealed! Though her mind was in shock, and trying to process what she was seeing, her body was already responding to the presence of a virile, masculine male alone with her in her room! Her nipples grew hard, her breath began to sharpen, and she clenched her knees together as she felt herself go wet...
Still, she tried to resist...
As he slowly pulled her top off, exposed her giant tits, and put his hand on the top of her head, she whispered, "...no...thith ithn't right...you're my mother'th huthband..."
He smiled down at her as he pointed his cock at her mouth. "Your mother knows what I'm doing, little filly. I told her when I married her that I would do whatever I wanted whenever I wanted, and she agreed." He stepped forward. "Now, open your mouth..."
Twist did open her mouth, but in shock at his words...which amounted to the same thing. He pressed his hips forward, and she went "GLRRKK!" as his cock slid inside past her soft, fat lips, and into her mouth. It wasn't her first time having dick in her mouth, but it was the first time a guy had done so without her permission.
And somehow, that made it more erotic!
She stared up at him as he took her by either side of her head and began pumping his cock in and out of her mouth, going deeper and deeper with each thrust, as she started licking and swallowing, trying to keep from gagging as more and more of his length was violating her throat. "Ahhh..." he sighed, "...you're your mother's daughter, all right. Your mouth feels just as good as hers..." Twist didn't know if she was pleased or insulted by his words, but she closed her eyes and sucked harder. He took his hands away as she started bobbing her head up and down on her own, apparently determined to outdo her mother when it came to dicksucking!
She pulled his cock out her throat, got on her knees while still on the bed, then told him, "Thpread your legthh..." as he willingly complied as she took him back inside her throat and swallowed him all the way to the base, pulled slowly back, and then swallowed him again while she placed her tiny hands on his thighs to steady herself. The sounds of his dick sliding in and out of her throat as she gulped and slurped, along with their pleasurable moans filled the room, and she could feel him starting to cum.
She knew what to do.
Wrapping her mouth around the head, she sucked and ran her tongue all around it while stroking the length as she watched his face, waiting for him to shoot his load into her mouth so she could taste every bit of it! She wasn't disappointed! With a mighty cry, he bucked his hips and cut loose, pumping creamy shot after shot of his spunk into her slutty mouth, while she did her best to gulp it all down! Her cheeks filled up like a chipmunk as he kept cumming, but she moaned as she reached her own climax from the taboo act she was performing: sucking her stepfather's cock and swallowing his cum!
Finally, his cum was too much for her and she fell back with a gasp, as his spunk spilled out of her exhausted, open mouth, down her chin, and over her fat tits. She looked down at herself, then ran her fingers through the gooey mess on her ample chest. She looked up at him through her glasses, brought a finger to her mouth and sucked on it, then whispered, "Your cum ith all over me...I guethh I'm your thlut, now..." He grinned.
"Almost..."
Before she could think, he suddenly grabbed her, spun her around on the bed, and threw her down on her face! "Wha...whath are you doingth?!" she cried as he positioned himself behind her and pulled up her skirt. She moaned as he gripped her panties and ripped them off with one powerful stroke, and then spread her legs with his knees. Reaching underneath her belly with one arm, he pulled her to a kneeling position as his cock slid in between her asscheeks and pressed against her cunt. He then took one hand and lined himself up with her pussy as she trembled with erotic anticipation, and then he sloooowly pushed inside. She moaned as she was entered, having never taken on a cock this size before, but she was already dripping and ready! "Yethhhh..." she moaned, "thathh it...tho DEEP..." He built up a steady pace as she continued to squeak, "Oh! Oh! Oh! Oh!" with each of his thrusts, as her body shook and her tits and ass jiggled every time he drove himself deeper.
But then, something happened she was not expecting! She felt him wet a thumb with her juices, and then slowly slip it inside her backdoor! She clenched her asscheeks together and looked back at him with her eyes wide. "Waith! Don'th...don'th think about ith!" He grinned again at her.
"Think about what?" as he pulled his massive cock out of her pussy, grasped her tail, and then lined his cock up with her virgin ponut! She began shifting her hips and tried to leap off the bed, but he was too fast for her!
As he pinned her back down on her stomach, she looked back at him and cried out, "You...you can'th!" She felt his cock line up with her ponut again, and she squeaked, "I've never done a...anal before UHHHHHHHH!" as his slick cock slid inside her! Her tongue lolled out and she moaned, "Uh! Uh! Uh! Uh!" as her ass was being fucked for the first time, and she felt her pleasure growing! She still tried to escape, wriggling her hips and arching her back, but he kept pumping her, as all her efforts only encouraged him! "You...you...bathard..." she moaned, as her eyes began to roll up and she felt an incredible orgasm approaching. She finally surrendered, laying her head on the bed with her tongue hanging out, and giving a long, drawn-out, "Ah...ah...ah...ah...ah...OHHHHHHHH..." as she felt him fill her insides with his thick, warm spunk. Her body shook as he fucked her once, twice, three more times after he'd cum, and then slowly freed his cock from her anus. Exhausted from her ordeal, she retained just enough strength for a final insult.
"You...animal..."
So, this became Twist's life from that moment on. Both she and her mother took to wearing slutty clothes from the moment they came home, for they never knew when they'd be called on to "service" the male of the house. Twist even started inviting a few of her friends over to...spend the night...so that her stepdad had a steady supply of fresh fillies for his "entertainment." But despite all this, she remained his favorite slut. Which, as she canceled her college plans, suited her PERFECTLY.
She truly loved being a slut.
