I am Lexi, a girly 17-year-old trapped in a biologically male body. I have a deep love for English literature and a build and vibe of a pretty cheerleader rather than some kind of ballplayer. With acceptance to Stanford in my pocket and a year of my mother's absence, I've learned to navigate high school as a sissy—a term I've grown accustomed to hearing. It didn't annoy me that much to be called a sissy, however, since that was what I actually was. Fuck it! I embraced being a sissy!

I was living with my stepdad, Ernie. Ernie was a man of few words. He spoke gruffly and profanely. At 44 years old, he was a burly man, 5 feet 9 inches and 210 pounds. He often scrutinized me with a mix of confusion and a yearning for the brawny son he had never had. He never understood me, or valued me.

Mom had run off with her lesbian lover last year when I was 16, leaving Ernie and me behind. We have heard little from her since. I miss her, but it seems that she doesn't miss me...or Ernie. I would like to brush it all off and say "que sera," but I can't. It hurts. There was a time when Mom and I were devoted to each other. We were inseparable. That time is gone.

Daily life with Ernie was a grind. The tension in our house was thick, like the smoke from his fat cigars. He tried to be nice to me, I know he did, but his efforts were awkward. He was never quite sure what to say to me, and when we did talk, it was usually about football or construction work. We were like two strangers forced to live together. He didn't get me, and I didn't get him.

One hot afternoon, I was out on the patio, sunbathing in just a skimpy thong… a girl’s thong I had bought at the mall. It was a bold move, even for me, but I figured if I'm going to be a sissy, I might as well be comfortable with it and enjoy my body. After a while, though, I went inside and plopped down on the couch to watch some TV. I was halfway through a 'Ren and Stempy' re-run when I heard Ernie's pickup pull into the driveway. Uh-oh! Ernie was home early and he wouldn't be able to handle me in just a tiny thong!

I jumped up, my heart racing, and tried to run to my room but it was too late. The door was flung open, and Ernie looked at me like he'd seen a ghost. "What the fuck are you wearing, Lexi?" he bellowed.

"It's just a thong, Ernie," I squeaked out. "Do you like it?" I asked boldly. Something told me that he liked it.

He took a step closer, his eyes wide with a mix of shock and something else I couldn't quite place. "What the actual fuck, Lexi? Since when do you wear... that… in my house?" His voice trailed off, and his gaze pored over my near-bare body.

I looked down at myself. "What? It's just kind of a bathing suit. I thought it would be nice to get a tan," I lied. The truth, of course, was that it was not a bathing suit at all, it was a very skimpy piece of girls’ underwear. It made me feel like I was a pretty slut.

"I think you like what you see, Ernie. I know I'm pretty. I have long legs and my ass is glass-smooth and shaped like a peach, Ernie!" I declared. There, I had said it! Proudly!

"Yeah, sure," Ernie said, his voice gruff but his gaze lingering. "You got legs like a supermodel, I'll give you that. And that ass!" He took a swig of beer, shaking his head.

I saw the bulge in his pants grow. My heart raced. I had him right where I wanted him. I walked over to him, my hips swaying a little more than usual, and stood directly in front of him. His eyes roamed over my body like I was a fucking all-you-can-eat buffet.

"Go ahead and kiss me, Ernie. I dare you," I whispered, looking up at him with a lustful gaze. "If you kiss me, you'll love me."

Without warning, Ernie grabbed me and crushed his lips against mine. The kiss was urgent, hungry. His rock-hard cock pressed against my stomach, and I felt myself melt into his arms. His cock was so much bigger than I had ever imagined, and the sensation of it made my own little cock stir in my thong. His hands roamed my body, squeezing my ass and my boy-tits. He didn't hold back, and for a moment, I forgot everything—the comments, the rejection, the pain of being misunderstood.

He broke the kiss and pulled down my thong. His cock was out now, standing tall and proud, and it was the biggest one I had ever seen. "You want this, don't you, you little sissy?" Ernie growled.

"Yeah, Ernie," I whimpered. "Fuck me hard, please. I need you and your cock!"

Ernie didn't waste a second. He bent me over the arm of the couch and lined his cock up with my tight hole. He pushed in, and it hurt—so much that I yelped—but I didn't want him to stop. The pain was a strange kind of pleasure, a thrill that shot through me like lightning. "Take it, you little whore," he grunted, his hand coming down hard on my ass.

As he fucking pounded me hard, I talked dirty, begging for more.

"Oh, your cock feels so good.” Pound. Pound.

“Oh my God, you're splitting me, Ernie!” Pound. Pound.

“I've never been this full.” Pound. Pound!

“Give it to me harder," I moaned. Pound. Pound!

My language was crude, but it only seemed to turn him on more. He pumped faster, deeper, and every time he slammed into me, I thought I was gonna come. He was rough, but it was the kind of rough that made me feel alive. The kind that made me realize that maybe, just maybe, there was something about me that Ernie liked after all.

My asshole stretched to the breaking point around his cock, and I could feel my orgasm building. "I'm gonna cum, Ernie," I panted. "Please, let me cum!"

"You can cum, but only when I say you can," he said, his voice strained with effort. "You're mine now, Lexi. Mine! You're gonna take every inch of me and you're gonna love it. Come now, little whore!"

And just like that, I came harder than I ever had before. Ernie followed, filling me up with his hot, thick cum. We collapsed on the couch, panting and sticky.

For a moment, we just lay there, with the sweat cooling on our bodies. Then Ernie sat up and pulled out, his cock still half-hard. He looked at me, his expression unreadable. "Don't tell anyone about this," he ordered.

"I won't," I promised, feeling both fear and excitement. "It'll be our little secret. Ernie, can I call you Daddy? I want you to be my daddy!"

Ernie's expression softened, and he stroked my hair. "Yeah, you can call me Daddy," he murmured, his eyes darkening with lust. "You're my pretty little sissy now. And Daddy's gonna take care of you. I think I'll call you ‘baby’ or ‘baby doll’ because you are a baby doll!"

I felt pure desire spread through me at the sound of his new names for me. It was weird, but it also felt right. Like I had found my place in a new world. "Thank you, Daddy," I said, snuggling closer to him. "Be good to your baby doll. I promise I will always be good to you!"

He pushed me down onto the couch, his cock already hardening again. "You liked that, didn't you?" he asked, his voice low and almost menacing.

"Yes, Daddy," I moaned. "I liked it so much. You feel so good inside me. You fill me up until it hurts so fucking good!"

Without saying another word, he flipped me over and pushed back into me. This time, he was even rougher. His thrusts were deep and hard, and each one felt like it was splitting me in two. "You're gonna be Daddy's good little bitch," he grunted. "You're gonna take every inch of me whenever I want it."

I nodded, eager for more. "Yes, Daddy. I want to be yours! Use me! Fuck me! Ruin me!"

He grabbed my hips and slammed into me, his cock demolishing my prostate with every stroke. I screamed out, the pleasure almost too intense to handle. "That's it, baby doll. Take it like a little whore," he said. His breath was hot on my neck.

As he fucked me, I realized that I was made to be used by a man like him. To be his dirty little secret. And I loved it.

But then, something changed. The pleasure turned to pain as he got harder, faster. "Daddy, it hurts," I whimpered.

He ignored me, his eyes glazed over with lust. "You can handle it," he said. "You're made for this, baby."

The pain grew, and I started to cry. "Please, Daddy. It's too much," I begged. But I was lying. Being fucked by Ernie was painful... but it felt so good. “Don’t stop, Daddy! Don’t ever stop!” I cried.

Then he just fucked me harder, his cock feeling like it might rip me apart. "You're mine," he said. "MINE!"

I could feel my body giving out, my orgasm building against my will. And then, with one final, brutal thrust, he came again, filling me with his cum. And then I came, spraying ropes of sissy cum in every direction.

As he pulled out, I lay there, feeling both used and loved. "Thank you," I whispered, my voice hoarse. "I love you, Daddy," I said with a tiny, trembling voice.

“I never thought I would find myself saying such a thing, But I love you, too, baby doll,” Ernie said tenderly.

The next day, Ernie was different. He didn't talk to me much, and when he did, it was in much colder tones. I could tell he was still trying to figure out what had happened, trying to figure out what it meant. But every time I saw him, I felt a thrill run through me. I knew that underneath, he wanted me just as much as I wanted him.

That night, after dinner, he called me into his room. I went in, my heart racing. I was wearing a cute floral sundress that Mom had left behind. That’s all. He was sitting on the bed, his cock already hard. "That dress is so pretty, baby, but I need you to take it off," he ordered.

I obeyed. This was it. Our secret life was gaining momentum.

He pushed me down onto the bed and climbed on top of me, his cock nudging at my hole. "You're gonna be my baby from now on," he said, his voice deep and commanding. "And you're gonna love it. I love you, Lexi… I can’t help myself! I love you way more than I ever loved your whore mother!"

As he pushed into me again, I knew he was right. It hurt, but it felt so good. And as he started to move, I realized that this was what I had been waiting for. This was what I needed.

"Yes, Daddy," I whispered, as he began to fuck me with a ferocity that bordered on violence. "Fuck me! Make me be yours! Force me to be yours!"

He grunted, his hands gripping my hips tightly. "You're gonna be my baby doll," he said, his voice thick with desire. "And no one else's. You're so fucking pretty!"

I nodded, tears streaming down my face. "I'm yours, Daddy. Only yours. Be my man, Daddy! Oh my god, you're my man, Daddy!"

And with that, he began to fuck me harder, his cock pounding into me like a jackhammer. It was almost too much to bear, but I took it. I was so eager to please him. His rough hands gripped my hips, leaving bruises that I knew would turn into dark and beautiful badges of our need for each other.

The room was filled with the smell of sex, and the sound of our bodies slapping together was lurid. "Bernie, give me the fucking of my life!" I screamed out, my voice hoarse and pleading.

He chuckled, the sound sending shivers through my entire body. "You want it, baby doll?" He asked, his voice like gravel. "You want Daddy to make you scream?"

"Yes, Daddy!" I screamed back, my body begging for more. "Please, Daddy, harder! Make me cry for it!"

He didn't disappoint. With a snarl, Ernie grabbed my thighs and spread me wide, pushing into me with a force that made me beg for mercy. Each thrust was like he was claiming my soul. "You like that, don't you, baby?" He groaned, his eyes never leaving mine.

I nodded, my voice a whimper. "Yes, Daddy. Hell yes, I love it! I love you, Daddy!"

The pleasure was so intense that I felt like I might pass out. But I didn't. I just kept taking it, begging for more. "I love you, Daddy," I moaned, my eyes rolling back in my head. "I love being yours!"

The next day, I walked through school with a satisfied smile on my face. Everyone had always seen me as merely a sissy, but now, I had something that no one else did. I had a daddy who loved me in the most powerful way possible. I strutted up and down the halls.

The whispers and giggles didn't bother me anymore. I had something the haters would never have. I knew that every time Ernie looked at me, he saw a sassy teen slut who was desperate for his cock. And every time he talked to me, his voice was filled with the promise of more to come.

That night, I crept into his room again, eager for more. I was wearing a mini-dress and a pair of stilettos I had bought online. He was waiting for me, his cock hard and ready. "You're one fine piece of tail, Lexi," he said, his voice a gentle rumble. "Come here and let Daddy take care of you."

I crawled onto the bed, my ass in the air like a good little whore. "Thank you, Daddy," I murmured, as he lubed me up and pushed into me once again.

The sex was once again intense and raw. His hands roamed my body, leaving a trail of hot sensations. "You're so fucking beautiful," he murmured, his voice filled with something that sounded almost like love. "So perfect for me."

As he pounded into me, I felt myself let go completely. All my inhibitions, all my fears, all my doubts—they disappeared, replaced by a single, overwhelming need for Ernie's cock. Cock! Cock! Cock! "Please, Daddy," I whimpered. "Please don't stop. You make me feel so full!"

He didn't stop. He just kept going, pushing me until I was screaming his name. And when I finally came, it was like a dam breaking.

Afterwards, we lay there, our bodies tangled. "You're my baby doll," he whispered, his breath hot in my ear. "Mine to fuck whenever I want."

And I felt truly happy. I had found my place. I was Ernie's baby doll, and I would take his cock whenever he wanted to give it to me.

And as the weeks turned into months, and my body grew more and more used to his. I found myself craving him more and more. I was crazy for cock. I was crazy for Ernie. I wanted to be used and abused by him, to be his little toy to play with whenever he felt the need.

And as long as he kept fucking me hard, I knew I would never let him go.
