The morning light streamed through the bathroom window as I stood in front of the mirror, towel slung low around my hips, brushing my teeth. The steam from the shower still clung to the air, and the faint scent of my body wash lingered. I was lost in my thoughts, mentally preparing for the day ahead, when the door burst open.

“Get out! I need to get ready for school!” My sister’s voice cut through the quiet, sharp and impatient. She stood there, her petite frame barely filling the doorway, her arms crossed over her chest. Her hair was a mess, and her eyes were wide with frustration.

I turned to her, toothpaste foam still in my mouth. “I’m almost done. Just give me a minute, ” I mumbled, trying to keep my cool.

“You’ve been in here forever! I’m going to be late!” she snapped, stepping inside and slamming the door behind her. Her hands were on her hips now, and her face was flushed with anger.

I spat into the sink and rinsed my mouth, then turned to face her fully. “Look, I said I’m almost done. Just wait your turn.”

She didn’t back down. Instead, she stepped closer, her eyes narrowing. “No, you’re done now. Move!”

Before I could react, she reached out and grabbed the edge of my towel. I tried to stop her, but she yanked it hard, and the fabric slipped from my body, leaving me completely exposed. My half-hard cock hung between my legs, and I felt a surge of embarrassment mixed with something else—something darker.

Her eyes flicked down for a moment, and I saw her cheeks flush even more. But she didn’t look away. Instead, she smirked. “What’s the matter? Can’t handle a little competition?”

I felt a rush of anger, and without thinking, I reached out and grabbed the waistband of her shorts. She gasped as I pulled them down in one swift motion, exposing her tight pink pussy. She was completely bare, and the sight of her made my cock twitch.

“That’s what you want, huh? You little whore, ” I growled, my voice low and dangerous.

She bent over to grab her shorts, but I was faster. My hand came down hard on her ass, the sound of the slap echoing in the small bathroom. She let out a yelp, and when she straightened up, there was a red handprint on her pale skin. Tears welled up in her eyes, but she didn’t say anything. She just stared at me, her lips trembling.

I didn’t wait for her to respond. I turned and walked out of the bathroom, leaving her standing there, half-naked and crying.

Later that day, I found myself in the car with my sister and her best friend, along with three of my buddies. The car was cramped, and the air was thick with tension. My sister sat on my lap, her short skirt riding up to expose her thighs. She was trying to ignore me, but I could feel the heat of her body against mine.

I couldn’t resist. My hand slid up her thigh, and she tensed. “Stop, ” she whispered, but her voice was shaky.

I ignored her and kept going, my fingers brushing against the soft skin of her inner thigh. She was trembling now, and I could see tears forming in her eyes again. But I didn’t care. I wanted her to feel it—to feel me.

My hand moved higher, and I was surprised to find that she wasn’t wearing any panties. My fingers brushed against her pussy, and she let out a small gasp. She was already wet, and the realization sent a jolt of arousal through me.

“Where’s your panty, little whore?” I whispered in her ear, my breath hot against her skin.

She didn’t answer. Instead, she tried to squirm away, but I held her firmly in place. My fingers dipped inside her, and she let out a soft moan. She was so tight, so wet, and I couldn’t help but push deeper.

On the other side of the car, her best friend was in a similar situation. My friends had her pinned down, their hands all over her body. Her shirt was ripped open, exposing her small breasts, and one of my buddies was sucking on her nipple while another fingered her pussy. She was crying, begging them to stop, but they didn’t listen.

I unzipped my shorts and pulled out my cock, which was now fully hard. My sister’s ass was pressed against it, and I could feel the heat radiating from her pussy. I adjusted her on my lap, positioning myself at her entrance.

“You like this, don’t you? You little slut, ” I whispered, my voice dripping with malice.

She shook her head, tears streaming down her face. “No... please...”

But I didn’t stop. I pushed inside her, feeling her tightness envelop me. She cried out, her body stiffening as I filled her. I grabbed her hips and started to move, thrusting into her with slow, deliberate strokes.

Her cries turned into moans as her body betrayed her. She was wetter than ever, and I could feel her clenching around me. I reached up and ripped her shirt open, exposing her small breasts. Her nipples were hard and pink, and I couldn’t resist leaning down to bite one.

She gasped as my teeth grazed her sensitive flesh, and I sucked on it until it was even harder. My hand moved to her other breast, squeezing and pinching until she was writhing in my lap.

“You’re such a little slut, ” I growled, my thrusts becoming harder and faster. “You love this, don’t you?”

She didn’t answer. Instead, she buried her face in my shoulder, her body shaking with pleasure and shame. I could feel her pussy tightening around me, and I knew she was close.

“Come for me, you little juicy girl, ” I commanded, slapping her ass hard.

She let out a loud moan as her orgasm hit her, her pussy clamping down on my cock like a vice and she released her girlie juices around my cock. I didn’t stop. I kept fucking her, driving into her with relentless force until I felt my own release building.

“Take it all, ” I growled, slamming into her one last time before I came deep inside her.

She collapsed against me, her body trembling as she tried to catch her breath. I held her close, my cock still buried inside her, and whispered in her ear, “You’re mine now.”
