“You’re such a dork, Alex,” my sister, Rachel, giggled as I tripped over the rug, my face turning a fiery red. I’d been trying to sneak a peek at the TV she was watching in her room. It was a show that I was pretty sure was rated R. “Just go back to playing your video games or whatever it is you do all day.” She rolled her eyes playfully, tossing a pillow at me.

“Come on, Rach,” I whined. “It’s not fair, you get to watch all the good stuff.” I couldn’t help but let my eyes drift down to her chest. Rachel had always had a killer figure, and lately, something had changed. She had the most amazing tits, and I found myself staring more than I should. I felt a little guilty, but I couldn’t help it. She didn’t seem to wear a bra much anymore, and her shirts had definitely gotten thinner.

As I stumbled back to my room, my mind couldn’t help but wander to those images. I had a pretty good stash of porn saved on my computer, mostly of girls who looked like Rachel. It was a guilty pleasure, one that I felt weird about, but it was something that I couldn’t shake. The sight of Rachel’s barelycovered chest had gotten me so worked up that I needed a release. I quickly opened my laptop and clicked through the tabs to find the video that would do the trick.

But tonight was different. As the scenes played out in front of me, Rachel’s face kept popping into my mind. I couldn’t shake the thought of her, and before I knew it, I was looking up porn. I didn’t know why, but something about the taboo nature of it was incredibly arousing. As I scrolled through the videos, I found myself getting harder and harder. The thought of Rachel was all I could think about.

I had to see her again, to see if there was any truth to my newfound obsession. I waited for her to go to the bathroom, and when she did, I tiptoed down the hall, my heart racing. The door was slightly ajar, and through the crack, I could see her silhouette in the mirror. She had her shirt off, and her hand was moving up and down. It was mesmerizing. And then, as if on cue, she leaned back, and I caught a glimpse of something that didn’t quite fit with the image in my head. Rachel had a cock. My brain screamed in shock as I stumbled backward, my hand over my mouth to muffle any sound.

I retreated to my room, my thoughts racing. I didn’t know what to do or think. Rachel was trans, and she had the most beautiful cock I had ever seen; it was huge—at least nine inches. I felt a mix of confusion, excitement, and fear. But as I lay there, stroking myself, I realized that I didn’t just want to watch Rachel on a screen. I wanted her, all of her. And I had to figure out how to make that happen without ruining our relationship or getting caught by our mother.

Over the next few days, I walked around the house in just my boxers, my semihard cock on full display, hoping Rachel would take the hint. She’d always been so shy about her body, but I figured if I was more open, she might feel more comfortable too. It worked. Rachel started wearing looser clothes, and I caught her looking at me more often. One evening, as we sat in the living room watching TV, she leaned over to grab a soda, and her shirt rode up. I could see the outline of her cock, and my heart skipped a beat. She didn’t bother adjusting herself, and I took that as an invitation.

We found ourselves in a silent dance of desire, both of us pretending not to notice the other’s glances and occasional accidental touches. The tension was palpable, like a live wire waiting to be tripped.

And then, one night, it happened.

We were watching a movie, and the scene got steamy. Rachel was sitting next to me, her legs slightly apart. I could see the bulge in her shorts, and I knew she was just as turned on as I was.

Without a word, I reached over and placed my hand on her thigh. She didn’t move away. Instead, she looked at me, her eyes dark with lust. Slowly, my hand moved closer to her cock, and she took a deep breath. I was terrified she’d stop me, but she didn’t. I wrapped my fingers around her shaft, and she moaned quietly. The moment was electric, and I felt alive in a way I never had before. Rachel’s eyes searched mine for any sign of rejection, but all she found was pure desire.

And then, she leaned in and kissed me. It was soft at first, tentative, but it grew more passionate with each passing second.

We broke the kiss, panting, and she whispered, “Let’s go to my room.”

My heart was racing as we snuck down the hallway, our mother none the wiser. As we entered Rachel’s room, she turned to me and said, “If we do this, we can’t tell anyone.”

I nodded, unable to speak. I knew I’d do anything to keep this secret. Anything to have Rachel.

Her room was dimly lit by the glow of her computer screen, which cast an eerie light over her face and her body. She turned to me, her cock still in my hand, and began to remove her clothes. She was so much more than just my sister now, she was a goddess in front of me. Her skin was flawless, her breasts small but perky, her nipples so puffy and pink they looked like little clouds. I couldn’t believe this was happening.

We tumbled onto her bed, our limbs entwined, kissing and touching each other. Rachel’s cock was thick and hard in my hand, and I stroked it gently, watching the pleasure ripple through her body. We were both naked, our bodies pressed together. Her skin was so warm, and I could feel the beat of her heart against mine. We kissed again, deeper this time, our tongues dancing together as we explored each other’s mouths.

Rachel pushed me onto my back, straddling my waist. She took my cock in her hand and began to stroke it, her movements sure and practiced. I moaned into the pillow, the sensation of her hand on me was like nothing I’d ever felt before. Then, she leaned down and took it into her mouth, her eyes locked on mine. It was the most erotic thing I’d ever seen, my sister with her big, puffy tits and massive cock, sucking me off like a pro. I couldn’t hold back anymore, and I shot my load into her mouth, watching as she swallowed it down.

We lay there, panting, our bodies slick with sweat. Rachel pulled me into a tight embrace, and I whispered, “I’m sorry,” into her ear. She shushed me and said, “Don’t be. This is who we are.” We fell asleep in each other’s arms, our bodies intertwined, our secrets shared. From that night on, we became lovers, hiding our relationship from our mother, finding moments of passion whenever we could. Our love grew stronger with each shared glance, each stolen touch, each whispered promise of more to come. And though we knew it was wrong, we couldn’t deny the pull we had toward each other. Rachel had become my obsession, and I had become hers. Our world had changed forever.

One evening, after another round of secret lovemaking, Rachel looked at me with a glint in her eye. “Let’s show Mom,” she whispered, her voice thick with excitement. “Let her see how beautiful we can be together.” The idea was thrilling and terrifying in equal measure. We knew our mother had caught us in compromising situations before, but she had always turned a blind eye, assuming we were just playing a prank. This time, we were going to be unmistakable. Rachel stood up and put her clothes back on, adjusting herself to hide her hard cock. I followed her lead, my heart racing.

We made our way back to the living room, where our mother was engrossed in a reality show. Rachel turned the TV off and announced, “Mom, Alex and I have something to tell you.” Our mother looked up, her expression one of mild annoyance that quickly changed to shock as Rachel dropped her pants, revealing her massive, erect cock. Rachel’s voice was steady as she said, “This is who I am now. And this is who we are together.”

Our mother’s eyes widened, and she sat there, speechless. Rachel took a step closer to her, and I could see the hunger in her eyes. “Don’t you think it’s time you joined us?” Rachel asked, stroking her cock gently. My mother’s gaze darted to my crotch, where my own erection was straining against my boxers. Slowly, she stood up, her hand moving to her own chest, where her breasts swelled beneath her shirt. Rachel took another step, and our mother took a deep breath, her hand moving to the button of her pants.

The moment was surreal, the air thick with desire and anticipation. Rachel stepped closer to our mother, and I watched as she reached out and placed her hand over my mother’s. Rachel whispered something in her ear, something that I couldn’t hear. And then, with trembling hands, my mother began to undress, revealing her own voluptuous body. Her breasts were indeed massive, her areolae dark and puckered, her nipples standing erect. Her stomach was soft and round, leading down to the V of her pussy, trimmed with a neat strip of hair. Rachel took her hand and placed it on her cock, and she gasped.

We stood there, a tableau of naked flesh and unspoken desires. Rachel leaned in and kissed our mother, and I watched as she guided her to the sofa. They fell onto the cushions, a tangle of limbs and passion. Rachel’s hand found its way to our mother’s pussy, and she began to rub it with the same expertise she used on me. My mother’s eyes rolled back in her head, and she moaned softly. Rachel looked at me over her shoulder, her eyes gleaming with mischief, and beckoned me closer. I knew what she wanted, and I couldn’t resist.

I joined them, my cock throbbing with need. Rachel positioned herself between our mother’s legs, and I took my place beside her. We kissed each other, our tongues dancing as our hands roamed over our mother’s body. Rachel took her pussy in her mouth, and I watched as she licked and sucked it. Our mother’s breath hitched, and she moaned louder, her hand gripping the back of Rachel’s head. I leaned in and took a nipple into my mouth, feeling it harden against my tongue. And as Rachel brought our mother to the brink of ecstasy, I knew that we had crossed a line that could never be uncrossed. But in that moment, all I felt was desire, pure and unbridled, for the two most important women in my life.

Without warning, Rachel sat up, her cock bobbing in the air. She reached for a bottle of lube on the side table and slicked herself up before she pushed into our mother’s pussy. The sight was indescribable, Rachel’s cock disappearing into our mother’s wetness, her eyes rolling back in pleasure. Rachel began to move, her hips rocking back and forth as she took her time, savoring every inch. Our mother’s hand found its way to Rachel’s chest, squeezing her small but firm breasts as Rachel fucked her with a passion I had never seen before.

Our mother’s hand reached out to me, and she wrapped her fingers around my cock, stroking me in time with Rachel’s movements. I watched as Rachel’s cock slid in and out, her beautiful breasts bouncing with each thrust. And then Rachel looked at me, her eyes glazed with lust, and whispered, “I want you to fuck me too.” I didn’t need any more encouragement. I lubed up my cock and positioned myself behind Rachel, pushing into her tight asshole as she continued to fuck our mother. Rachel’s moans grew louder as she felt me inside her, and our mother’s eyes went wide with surprise and pleasure.

Our mother took Rachel’s breats into her mouth, her tongue swirling around the nipples as Rachel and I fucked in a rhythm that seemed almost choreographed. Rachel’s moans grew more urgent, and I could feel her ass tightening around my cock. We were all lost in a world of pleasure, a world where the only thing that mattered was the feel of skin on skin, the taste of sweat and lust. And as Rachel’s orgasm washed over her, she collapsed onto our mother, her cock still buried inside her. I pulled out and came all over Rachel’s back, my own release a hot, sticky mess.

We lay there, tangled in the aftermath of our passion, our bodies shaking with the intensity of what we had just done. Our mother looked at us, her expression a mix of shock and arousal. Rachel kissed her softly on the cheek, and I knew that our lives had changed forever. We had become a family in every sense of the word, and there was no going back. The secret we shared was no longer just about Rachel’s body but about the love that we had found in the most unexpected place. We were bound together by more than blood, and as we lay there, I realized that I had never felt more alive, more accepted, and more loved than I did at that moment. Our mother reached out and stroked Rachel’s hair, a silent promise that she would never leave us. And we knew that we had found a love that would never be broken, a bond that was stronger than any taboo or societal norm.
