Hot Girl Summer - Part 2

“FUCK YOU! GO TO HELL!” Millie screamed at me, tears streaming down her cheeks as she stormed out of her room, slamming the door behind her.

The echo reverberated through the house, but it barely registered in my mind. I was too busy adjusting the straps of my tank top, feeling the fabric snug against my new curves.

As I twirled in front of the mirror, admiring my new body, Millie’s words echoed in my mind. Our relationship had deteriorated rapidly since the body swap. We had always been close, but now we barely spoke to each other unless it was necessary.

I wasn’t surprised by her outburst. She had been growing increasingly frustrated with the situation and I couldn’t blame her. After all, it was her life that I was living now.

But I couldn’t bring myself to care. This new life was too exciting and fascinating for me to give it up already, just because she was unhappy.

I leaned a little closer to the mirror, giving my hair a playful toss while adjusting the bright lip gloss I had swiped from Millie's vanity. The thrill of embodying her life consumed me.

I always knew she’d be upset when she found out I’d been fucking her boyfriend.

My fingers trailed along the graceful curve of her neck, following the delicate lines down to the gentle swell of her cleavage. A soft sigh escaped my lips as I reveled in the ability to touch this body however I desired. The smoothness of her skin under my fingertips sent a shiver of pleasure through me. These breasts, though they belonged to my own sister, were a source of fascination and desire for me. Despite any societal taboo, I couldn't deny the intoxicating sensation of having them in my grasp.

This body had already given me so much pleasure. My fingers slipped in between my legs.

Just then, the door creaked open.

Millie stood there again, her eyes wide with disbelief, “What are you doing?!”

I turned towards her, but I did not stop touching myself.

“Stop it! You’re gross!” she shouted, her voice breaking.

I smirked, refusing to halt my exploration, “It’s my body now, remember? I can do whatever I want.”

I moaned as I stared into her eyes.

“You’re sick!” she spat.

“Am I?” I challenged, a playful grin spreading across my lips as I leaned back against the dresser, “Or am I just embracing what you’ve always taken for granted?”

My fingers traveled deeper, as I grabbed my breast with my other hand. I moved to the bed and lay down on my back, spreading my legs wide open as I continued to touch myself.

Millie stared at me in horror, her face pale and shaken, “Leo! Stop it! You’re in my body! You’re my brother! You can’t just—”

"Oh, sweet, naive Millie," I purred, my eyes locked with hers as I continued to stroke myself, "I'm not your brother anymore, remember? I'm you now. And as you so proudly proclaimed, I can do whatever I want."

I moaned louder this time, intentionally drawing out the moment as I rubbed my clit in slow, firm circles. I could feel myself approaching climax.

Then, just as she reached out and grabbed my shoulders, I came.

I gasped, arching my back as waves of pleasure coursed through me, my breath hitching in my throat. Millie’s hands fell away in shock, her expression a mixture of disgust and disbelief.

“Welcome to your new reality,” I said, still riding the aftermath of my release, completely unfazed by her horror.

“But you’re my brother!” she insisted.

“I’m your sister. I’m your sister. And that means I get to live like a girl—like you—fully and unapologetically.”
