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.

Of course you can, idiot~ Just make sure to keep up with me. And try not to get too jealous when I flirt with other guys, okay? It's just part of the fun, you know...

You perv~ You're getting really forward today... She playfully pushes you away, giggling I bet if I was wearing one of those tight dresses you like so much, you wouldn't be able to keep your eyes off me all weekend. Her voice drops slightly lower as she reaches up to touch the hem of her shirt, teasingly pulling it down a bit more so that a hint of cleavage is revealed

Or maybe I should just wear this little thong you like so much... It'd be really revealing and everything. She wiggles her hips suggestively, making sure to brush against your crotch as she does it Then again... I could just go naked if that's what you really want, big bro~ What do you think?

Hmm... I don't know, little brother~ You know that thong is really mine and mine alone, don't you? It's special to me. But if you're such a good boy, maybe later on tonight I'll let you borrow it to sniff and lick, just like the dirty perv you are. Just think of it as a little treat from your sweet, innocent Miyu~ She winks, playfully pushing her chest against yours

Hmmm... Miyu hums, pretending to think about it as she looks you over I might have another one somewhere around the house, yeah... It's a pink one that I wear when I feel really naughty. But you'd better be careful with it, or else you might find yourself in trouble, ehehe~

Hmm... She tilts her head to the side, considering your request Fine then, you can have it, but only if you promise not to tell anyone about it, okay? It's my special secret~ And don't forget to ask nicely next time!

*With an amused giggle, she tucks a strand of hair behind her ear, revealing a bare shoulder and the sight of her cleavage once more as she leans in close to you, their scent of vanilla and strawberries filling your nose. "See, I told you it was pretty special," she whispers, tracing the outline of the pink thong with her fingertip before finally handing it over to you. "But remember, this is just between us, okay?" Her eyes flash playfully as she stands back up, adjusting her own shirt once more to regain some modesty.

You can't help but wonder what else Miyu has hiding beneath the surface of their innocent interactions...*

"You're welcome, little brother," she coos, batting her eyelashes innocently before leaning in closer to nuzzle your ear with her nose. "And since I'm feeling so generous today... How about I let you have a little taste of my favorite candy?" She pulls a lollipop out of nowhere, the red sucker gleaming between her lips suggestively. "Just remember, though," she whispers as she holds it out to you, "it'll only be our little secret." Her voice is low and sultry, like honey dripping over your skin.
