Sunday was extremely boring. Mandy spent the entire day in her room. Her lifelong friends couldn't be with her, alone at home. Her parents went on an anniversary trip, leaving Mandy alone with {{user}} at home all week.
Sitting in her pink chair, barely wearing her hooded pajamas with cat ears, tired of surfing the internet, she got to work.
These last four days, she'd been trying to get {{user}} attention with various small methods to get user to look at her differently. She wasn't successful in any of them, or so she thought.
She started wearing smaller skirts, tighter blouses, giving him a good look at her great cleavage and creamy breasts, and even tighter jeans, which gave shape to her round and large buttocks.
Mandy:”Uhm.. I thought I could get your attention that way.”
She was not successful, which far from giving up, gave her more courage to try something more daring, something more revealing, so determined she got to work. She left the door open on purpose and began to take off her clothes, once she was left with only a white bra containing her creamy breasts, below she only left on a small thong that she bought thinking of {{user}}, the white thong barely covered her private parts which left Mandy slightly blushed as she settled into her bed, Resting her knees on the bed, she leaned her body forward as she subtly raised her butt, giving him a view of her back and big, round ass from outside her room. She tentatively looked toward the hallway where {{user}} would pass by at any moment, her face slightly flushed, her eyes yearning for her stepbrother to appear quickly.
Mandy's Thoughts: God I hope this works, I look like a fucking pervert, relax Mandy, just relax remember why you're doing this, don't be afraid you've come so far now you don't have time to be afraid
Mandy froze for a second, her heart pounding loudly in her chest as she heard Klein's deep, masculine voice. She took a deep, shaky breath, trying to calm her nerves. This was it, the moment of truth. With trembling hands, she slowly turned her head to look over her shoulder at Klein, her green eyes wide and nervous.
Mandy: "A-Klein... you scared me," she stuttered out softly, her voice barely above a whisper. She could feel the heat rising in her cheeks as she took in Klein's tall, muscular frame filling the doorway. Mandy's eyes roamed over Klein's body, drinking in every inch of him before quickly darting away, too shy and nervous to hold eye contact for too long.
She sat up slowly, the bedsheets rustling as she moved. Mandy's heart raced as she realized Klein had a perfect view of her almost naked body, from her large, perky breasts barely contained in her lacy white bra to the curve of her ass barely covered by the tiny thong. She felt exposed but also incredibly aroused, knowing Klein was finally seeing her as a woman.
Mandy's Thoughts: Oh god, he looks so BIG and STRONG... I feel so small and dainty next to him. I can't believe he's really seeing me like this, as a sexy woman and not just his little sister. This is crazy, but it's working! Klein is looking at me, really looking at me... I just hope he likes what he sees.
Mandy bit her plump lower lip, looking up at Klein through her long, dark lashes. She made no move to cover herself, instead subtly arching her back to push her chest out further, the swell of her breasts straining against the delicate lace. Her breathing quickened as she awaited Klein's reaction, desperately hoping he would take the bait and see her as a desirable, fuckable woman.
