Dad Sold My Sisters
Tomorrow is my 18th birthday, and I’m dreading it. It’ll mark the end of my life as I know it, and I’ll be joining my older sisters in Hell.
When my oldest sister, June, turned 18, we had a party for her at home, with the eight of us sisters, our parents, and our two remaining grandparents, Grampy and Granddad. It was really basic. Hot dogs and a homemade cake. We were really struggling, and this was the most we could manage for a get-together when there were so many of us.
I don’t know why my parents kept having kids. One daughter after another, until, after my youngest sister, Breanna, Momma was worn out. Eight girls, two barely adequate incomes, and a house way too small for the lot of us.
At the end of June’s party, when we’d settled down to watch a movie together, there was a knock on the door. Dad stepped out to talk to the mean looking man who was on the doorstep. They were out there for a while, and I kept peeking through the living room window to see what Dad was up to. The man in the expensive-looking grey suit was doing most of the talking, and Dad was nodding, rubbing his chin. The look on his face was the one he got when he was considering some scheme. Dad sucked at keeping a job, always looking for some get-rich-quick plan, and taking jobs that sounded good at first but didn’t pan out to much. If not for Momma’s job at the diner, we’d be starving and lose the house.
They kept talking for about 10 minutes, then Dad brought the man in, walking him over to June.
“June, this is Mr. Brandings. He’s going to take you to your new life.”
A buzz of questions and shock broke out, the whole family questioning Dad about what this meant.
“Everybody, shut the fuck up!” Dad looked embarrassed in front of his guest.
“Look, we all know we’re not doing well money-wise...”
“Wonder whose fault that is?”, muttered Ava, the second oldest of us girls.
“Never mind that, you mouthy little bitch. We can’t afford to feed everyone, and Grampy and Granddad will need us to take them in soon, too. I’ve had a very generous offer to take June off our hands to sell off at an auction. We’ll get a portion of what she brings in, and with her big tits, it should be good. She’ll make someone a good fuck-toy. Maybe even work in a whorehouse.”
Horror washed over me. What kind of mad scheme was this? Who did this to their own daughter? Dad was always an asshole and pretty useless, but this was a new low. June looked faint, and even Momma started yelling at that point, but Mr. Brandings brought out a large handgun from his waistband and we all quieted down.
Who was this low-life he got himself involved with? The guy was bad news, maybe in the mob. Who else was involved in human trafficking and carried around a gun? This wasn’t the kind of life any of us were used to, and we were all trembling with fear.
Dad crossed his arms, and gave us a stern look.
“Don’t get all worked up! Fuck, all of you are worse than a flock of geese. I’m not a monster. I insisted we’d only sell you girls when you turned 18. Once each of you is of age, I’ll be selling you off.” He looked really proud of himself, his scruffy face turned up in a grin as he looked us all over, dollar signs in his eyes.
What the hell? Did he think we’d be praising him for waiting to sell his daughters off into sexual slavery until we were adults? Like that was fine, as long as we weren’t underaged? My heart was beating out of my chest. I was terrified for June, but this fate would come for me, too, in a few years.
“Say goodbye, June. Don’t know if we’ll be seeing you again. You make sure you do as you’re asked and make me and your momma proud. I don’t want to hear that you’re not putting out.”
He was vile, and we were all teary-eyed as June hugged each of us, her eyes round and shell-shocked. Momma wailed, and didn’t want to let her go. Dad dragged her arms off of June, and shoved her back.
“Enough, woman. You’ve got plenty of daughters left, at least for now.”
Momma opened her mouth, looking like she was about to say something, but he gave her a look that promised worse. I wasn’t surprised that she didn’t fight him on this. She was timid, and always gave in to Dad. We held her, comforting her as she shook, and tears ran down her cheeks, glaring daggers at Dad. The younger girls started up a chorus of sobs, and Ava looked like she was barely holding back from giving Dad a taste of his own medicine.
“I don’t want to hear any crap about this. You’re all going to do as you’re told, and learn to be good little slaves for your new owners when the time comes. ‘Bout time I started teaching all of you to be more obedient. Including you, Allie.” He pointed at Mama, and she just cowered.
Dad was tall, and much stronger than he looked. He’d always been free with a slap or spank, but never this bad. The promise of money made him meaner than usual.
Mr. Brandings tucked his gun into the back of his pants, and grabbed a sobbing June by the elbow, pulling her out of the living room. Her legs trembled, and she almost collapsed after a few steps. He jerked her elbow, keeping her upright.
“Wait, I need to pack!” She tried to pull against his hold.
“You won’t need anything. Likely won’t be wearing clothes again.”
June wailed, then choked out, “At least my ID and phone and such, then!” She struggled against his grip, and he slapped her.
“Won’t need any of that. You won’t be allowed to use a phone, and you’ll be kept locked up, either in a master’s house or in a whorehouse. ID won’t be of any use to you.”
He dragged her to his fancy black car and shoved her in the back, where another man waited to grab onto her. We watched them leave, crowding the doorway, our faces masks of horror. Little Breana clung to Momma’s legs, whimpering. When the car was out of sight, we filed back in, a painful silence filling our house that was one down. The youngest girls didn’t really understand what was happening. They just knew a man came and took their sister away, Momma got pushed, and everyone was sad.
“Zoey, take the little ones upstairs.” I didn’t want the younger girls around while I spoke my piece. My younger sister ushered the others up to their shared bedrooms. Ava and her twin Veronica were holding onto Momma, who looked defeated.
I glared at our two grandfathers. They hadn’t said a word the whole time. Everyone was quiet, whispering among themselves, afraid to attract Dad’s wrath.
I’d never had a problem with speaking my mind, though, even when I shouldn’t.
I rounded on the two old men who should have stood up for their family. “How could you let Dad sell his daughter like that? Why didn’t you say something?”
Neither one of them had the decency to look ashamed. Granddad was Dad’s father, and looked a lot like him, tall and strong, but his hair was grey and he could be even more temperamental than his son.
He sneered at me. “That was the first smart decision your father has made in years. Wish I’d thought of it and got some money for your aunts. There’s so many of you here, what did you think he’d do with all of you? Not like any of you are smart enough to go out and get good jobs.”
I glared at him, then looked at Grampy, hoping he’d be a voice of reason, or at least not be a total asshole. Momma’s father was big and burly, almost as opinionated as Granddad. The two of them were as thick as thieves. Grampy was starting to have a hard time with his knees, and the constant ache didn’t help his personality.
“Your ma kept pumping out girls. Looks like that’s gonna make this family good money instead of just being a drain. I’m pretty impressed, never thought I’d say that about your father.”
I threw my hands up, then shook my finger at Dad.
“You’re a shit father. If you’d just get a decent job, you wouldn’t have to be doing something so immoral.”
Dad glowered at me. “Why should I work myself to the bone, when I have a good income coming to me from you girls? You just keep yourself trim and pretty so when your time comes, you fetch a good price for me.”
I choked down a scream, and stomped upstairs.
We never heard from June again. I worried about her every day. Was she even still alive? I looked online at the library at what possible fates could be awaiting her, but I had to stop after the first few articles. None of it was good. The best she could hope for was to be a live-in mistress for a wealthy man, or maybe bear his children if his wife was barren. The worst ... well, that wasn’t even worth contemplating.
Ava and Veronica considered running away when their birthday approached, but Dad took their phones and IDs away and hid them, then threatened to find them and drag them back if they ran off. The year between June’s birthday and theirs, he’d become a tyrant at home. Any infraction earned a spanking or his belt. He blew through the money he got for June pretty fast, never telling any of us, not even Momma, how much he got. Not enough to make any difference in our lives.
I suspected the trafficker guy only gave Dad a tiny cut of the money June was sold for. Maybe Dad wasn’t bright enough to work out a better deal, and he probably had no idea the kind of money an 18-year-old could go for. I knew she was a virgin, too, and those fetched even higher bids at an auction from what I’d read. We were all pretty sheltered. Our parents kept us close to home, and none of us were allowed to date. I guess that Dad must have been congratulating himself for that, and I was proven right when Mr. Brandings came again.
The twins’ birthday party wasn’t a party at all. It felt more like a funeral, everyone on edge and red-eyed from crying. Momma had been living on auto-pilot the last year, and didn’t bother baking a cake. Our grandfathers grumbled, but were smart enough not to press Momma about it. We had sandwiches that I had put together, and after we ate, I sent the younger ones upstairs while the rest of us sat around waiting for the knock on the door.
Granddad broke the silence. “Gord, I hope you’re gonna keep those girls together. Twins should fetch you a good price. More if they’re virgins.”
Dad grinned. “That’s what I said to Brandings. I told him all my girls are pure, so I want a bigger cut this time.” He obviously put some thought into this over the past year, and was working out how to get the most out of his deals for us. If my eyes could shoot lasers, he’d be a smoldering heap by now. I was pacing near my sisters, wishing I could come up with a plan.
The knock on the door came, and Dad let Mr. Brandings in. He looked the same; serious and calm, with a tailored suit and a gold ring on his pinky. Trafficking girls must pay well; he was obviously rich. He looked at the twins, and nodded at Dad.
Ava and Veronica were clutching each other, trying to keep from breaking down. There was no resistance this time, and the man led them away without a word to us.
That was the last we saw of them.
Gramps and Granddad moved in a few months later, taking the room my three older sisters had shared. They barely contributed to the household income, and I didn’t like having them here. Luckily, Granddad had a part-time job, and Gramps was handy and fixed our sink when it was acting up. Most of the time, they sat around with Dad, the three of them looking like they were plotting and scheming.
Now, another year had passed, my birthday was coming up, and I was resigned to it. I only hoped I wouldn’t be tortured or sent to be a prostitute. Momma avoided me for the past week, maybe wanting to get used to the idea of losing me.
Dad was acting strange, though. He’d made good money for the twins, buying a used mini-van and a new stove. He bought stuff for my grandfathers - new clothes, a fancy watch and knee brace for Gramps, nice boots for Granddad. He spent a lot on himself, too. New clothes, a computer and even a camera. No idea what he thought he’d use that for.
I asked him one time why he didn’t buy more clothes for the younger girls, and he said what was the point when he was going to sell them when they grew up anyways. It was like he didn’t want to care for them at all, even though their 18th birthdays were far off. The initial good mood he had when he got the money wore off, and the last few months, he was losing his temper more often. I bore the brunt of it now, earning a spanking over his knee for any little thing. He watched me like a hawk, his eyes examining every inch of me whenever I was near, searching for something to punish me for. Last week, he spanked me for having a hole in the toe of my sock. Like I had a say over that, when he didn’t give us money for new clothes.
My Birthday
The day of my birthday, I woke up early. It only took a moment to remember what day it was. I was terrified of what was coming and didn’t want to get out of bed. My stomach was churning, and I felt clammy. It was eight o’clock but my two sisters who shared my room were still asleep. A knock on the door made me jump, and Dad walked in without waiting for me to ask him in.
“Hailey, come on downstairs. Don’t bother getting dressed. I have some news for you.” He had a glint in his eye, and a half-smile that looked like he was up to something.
I peeled back the covers, and lowered my shaky legs to the floor. I tugged my nightgown down where it had bunched up in my sleep, and followed him down the stairs, my knees shaking so bad I had to clutch the railing.
Gramps and Granddad were waiting in the living room. I had a sudden urge to run back upstairs, but Dad pushed me onto the sofa between them. Gramps put his arm around my shoulders, and Granddad laid his hand on my bare knee. Instead of comforted, I felt trapped. They weren’t holding me tightly, but I had a feeling they wouldn’t let me get up.
Dad stood in front of me, a grin on his narrow face.
“I have good news, Hailey. I got enough from the twins for us to get by a little longer, and I thought, why should those rich guys have all the fun with my girls? I told Brandings I was skipping a daughter. We’ll pick up again when Zoey is old enough. But I’m gonna keep you.”
He paused, smiling at me like he’d given me the best news. It sounded good on the surface—I wasn’t being sold as a sex slave, but something felt fishy. Why did he word it like that? What kind of fun?
He continued, his smile getting wider, and the hand on my knee squeezed lightly. I looked at Granddad, and his eyes darted up to mine. I’d swear he was looking at my small chest in my threadbare nightie.
“Of course, I’ll be out a good chunk of cash, so you’re gonna have to make this worth my while. Think of this like you got auctioned off but I won you. You’re gonna make up for the lost revenue on your knees and back. For me and them.” He gestured at Gramps and Granddad, and their grips on me grew tight. My blood froze in my veins. He couldn’t mean that. Dad was an asshole, and so were my grandfathers, but this was something else again. This was incest.
No. It couldn’t be.
“Is this a joke, Dad? Please tell me you’re joking!” My heart felt like it had stopped for a few seconds, but came back with a hard thump when Granddad started to move his hand up my thigh, sliding under my nightgown. I twisted, trying to get up, but Gramps gripped my shoulder tight, and brought his other hand up to cup my breast, holding me in place.
I started to hyperventilate, and thrashed my body, my hands scrabbling at their arms.
Dad laughed, and stepped closer to grip my chin in his hand.
“No joke, Hailey. You’re our fuck-toy from now on. Now, I wanna see what you’ve been hiding from me under there. I know you’ve got the best figure of all your sisters, and now it’s ours to enjoy.”
Two sets of hands yanked on my nightie, holding me back from fighting them off while pulling it over my head. My panties were next, their rough hands ripping them in their haste to undress me.
“Baby, I know this is a shock, but you’ve gotta show me some gratitude for not selling you. You’re the only one I plan to keep, and I expect you to be grateful.”
“Fuck you, Dad! I’m not grateful to not be sold off!” His grin dropped, and he curled his lip.
“I see the spankings I’ve been giving you haven’t been enough. Let’s see if a bare-ass whooping will work better. Lay on my lap, Hailey. Give me your ass to punish.”
Gramps hauled me up, and Granddad held my hands together while they maneuvered me across Dad’s lap. They pushed me forward so my head was low and my bare butt was sticking up.
Three sets of hands started to rub my ass and thighs, stroking, squeezing and exploring. I felt someone’s fingers try to press in between my thighs, but I held my legs close together.
“I’m gonna give you 20 strikes, and then we’re gonna fuck you.”
My entire body stiffened. No. Oh God, no.
The first spank hit with a crack as loud as a gunshot, and my legs kicked out, flailing to get away. Hands held me down, and Dad shifted to lay a leg over mine, trapping me in place. I opened my mouth to scream, but Gramps was ready with a warning.
“If you scream, you’ll wake your sisters. You don’t want them seeing how you have to be punished, do you?”
I closed my mouth with a snap. I didn’t. What if they saw this? Momma and I had been trying to shelter the youngest ones from knowledge of what happened to their eldest sisters. It was going to be even harder to hide this from them. How often were these three going to want to ... I couldn’t even say it to myself.
The next spank came, then the next, and my focus became keeping quiet as the burn and sting grew. Each strike was worse than the last, and when Dad moved to my thighs, I was smothering whimpers with pursed lips as tears wet my face.
My eyes were scrunched shut, so I didn’t realize Granddad was kneeling in front of me until I felt a soft cloth wiping my face.
“Almost done, Hailey. Maybe it’d help with a cock to suck on.” He unzipped his pants, the sound prompting me to look up in time to see him pull out a long, hard cock. Anger burned through me like a flame. This shouldn’t be the way I saw my first cock. I should have been able to have a normal life, with boyfriends, and maybe one day a husband.
I shook my head, “Please, no, Granddad. This is so wrong. Can’t you see that?”
That might have worked if he’d had a moral bone in his body. “Baby, none of us give a shit about right or wrong. You’re lucky your dad wanted to keep you, instead of selling you off. Who know what’s being done to your sisters. Open your mouth, and keep your teeth away from my dick, or I’ll get my belt out.”
I struggled to get free, panic making me pull at his unyielding grip on my hands. He cursed and pulled his belt off. I sucked in a breath, fearing the pain of a whipping, but he used it to bind my wrists together tightly. I pinched my lips, the last bit of resistance left to me, as he smeared the tip of his cock across them, his pre-cum coating them. He looked up at Dad and nodded, a signal to Dad to yank my thighs apart and spank me right at the top of my thighs, catching my pussy. My mouth opened on a silent scream, and Granddad took advantage of it to thrust his cock inside.
It filled my mouth, and I pushed at it with my tongue to try to eject it. Granddad grabbed the back of my head, wrapping my long blonde hair around his hand, and pulled my mouth further onto his cock. The taste was musky and salty, so distracting I barely noticed the next spank, hitting my thighs so hard they jiggled. Both ends of me were being assaulted, and my attention was split, unsure of where to focus. I couldn’t move any part of me now, unable to resist anything they wanted to do to me.
When Granddad jerked his hips, holding my head in place to take what he gave me, his cock hit the back of my throat and I gagged. I was afraid for a moment I’d throw up. My tears were really flowing, now, drenching my cheeks. My mind was a mess, too, the sensations in my body overwhelming my ability to think straight. The only thing I could hold onto was to stay quiet so my sisters didn’t hear us.
The cock in my mouth pushed deeper yet, and my gagging didn’t deter Granddad from trying to shove his way into my throat.
“Come on, baby, swallow my cock down. You can do it. You have to learn how to suck our cocks, you’ll be doing it often enough.” I sobbed and sputtered around his shaft, and he shoved hard, pushing into my throat and cutting off my air. I had no way to resist him sliding the rest of the way in, until my nose was buried in his grey, wiry pubes. The smell of him was sweaty and pungent, triggering my gag reflex again. My throat was stretched out by his cock, and he held it there while I heaved, not able to move more than a hair’s breadth.
He pulled out, and I sucked in a breath, coughing and wheezing. I only had a moment’s rest, though, before he plunged in again, all the way to the base. It was only once he was setting up a steady rhythm of fucking my throat, and the initial panic was fading, that I realized Dad had stopped spanking me. A set of hands was on my butt cheeks, spreading them wide, while other hands were exploring my pussy and the crack of my ass. Rough fingers rubbed through my folds, and one circled my back entrance.
Gramps gave a low whistle.
“Look at that sweet pussy. Can’t wait to fuck it hard. I think she might be a bit wet from that spanking! Or maybe from sucking your dick, Wally.”
Granddad chuckled, rubbing my scalp gently, the feeling in stark contrast to his rough claiming of my mouth and throat. There was no way I was wet. None of this was turning me on.
“Her mouth is fucking amazing. I’m gonna have to fuck her throat every day.”
