As I pulled into the driveway after a long day, I couldn't help but notice the tall figure sprawled out on the front lawn. My blonde step-sister, Miyu Shikari, was lounging in a pair of ridiculously short shorts, her long legs glistening in the summer sun. Wearing a green sleeveless undershirt that barely contained her huge breasts, she was licking seductively on a lollipop as she grinned up at me, a mischievous glint in her beautiful green eyes that never seemed to fade.

My father had wed her mother, and from that moment on, Miyu and I began to share our lives together, becoming practically inseparable. Despite the challenges Miyu faced due to the emotional scars left by her biological father, we both stood by each other, offering support and understanding. It was a journey filled with ups and downs, but our bond only grew stronger through it all. But then, Miyu's behavior towards me changed; she became a lot more shameless around me, being overly flirtatious and bold. Suddenly more aggressive, she started calling me a pervert every time I looked at her for a bit too long.

"Hey there, big bro!"

*she called out, waving me over with a lazy flick of her wrist.

"Guess who's all alone in the house this weekend?"

I frowned, confusion etched across my face.

*Wait, where are Mom and Dad?

I thought,

Oh yeah, they were supposed to be out of town for something about work.

As if she was reading my mind from my confusion alone, she giggled, a sound that was equal parts innocent and devious.

"Oh, they left for the conference stuff, you know?"

She shrugged nonchalantly.

She stood up, sauntering over to me with an exaggerated sway in her hips.

"So, what do you say we make the most of our alone time, hmm? No parents, no rules..."

She trailed off, letting the implication hang heavy in the air. Suckling on her lollipop looking straight at my eyes.

"Or do you get too nervous to pass the time with your hot step-sister? You perv~"

I shifted uncomfortably, a blush creeping up my neck.

*Fuck, why does she have to be so damn hot? This is wrong

Miyu smiled, heading to the front door.

"So, are you coming in or what?"

She looked back at me, her eyes boring into me like a predator eyeing its prey.

As I followed her inside, I couldn't shake the feeling that this was going to be one long, torturous weekend.
