Sophia stood in front of the window display of a youth clothing store, her blue eyes fixed on the mannequins dressed in colorful t-shirts and ripped jeans that would suit Yasser's age. The sun was still high, striking the glass and reflecting her image like a large mirror: the tight black top clung to her heavy breasts, the shiny pink "HOT" stretched across her prominent curves, her erect nipples clearly visible through the thin fabric as if calling for attention. The extremely short denim shorts barely covered the front, and from behind her large rounded ass cheeks were almost completely exposed, the soft white flesh gleaming under the sunlight and jiggling lightly with every small movement. The thin shorts disappeared deep between them like a string, accentuating the natural, seductive curve.
Yasser stood beside her, gently holding her hand, his eyes shifting between the clothes in the display and his sister's body right in front of him. He was silent, breathing a little fast, his face still flushed from the looks he had seen at home and all along the street.
Suddenly, Sophia felt small, warm, hesitant fingers brushing against the cheeks of her ass from below. The touch was very light at first, almost accidental, but then it became steadier. Yasser's fingers—while he still held her hand with one of his—slowly extended, touching the soft exposed flesh, pressing gently as if testing whether she would stop him or not.
Sophia didn't move. She didn't flinch, didn't pull his hand away, didn't say a word. She stood perfectly still, her eyes still fixed on the mannequin in the window, as if she hadn't noticed the touch… or as if she had noticed and was quietly enjoying the strange sensation. Her body relaxed slightly, her ass lifting just a little under his hand, allowing his fingers to sink deeper between the soft cheeks, feeling the warmth and smoothness beneath them. Her breathing grew deeper, her chest rising and falling slowly under the top, the word "HOT" stretching with every breath, her nipples hardening even more beneath the fabric.
She loved him—Yasser, her little brother, the one she always protected in her dreams and who worried about her. This touch wasn't aggressive; it was innocent curiosity mixed with a forbidden boldness, and she… let him do what he wanted. She didn't protest. Instead, she shifted her body slightly to the right, giving him more space, letting her ass cheeks push out more under his fingers, the soft flesh jiggling lightly with the gentle pressure.
Yasser stood behind her, his eyes fixed on the window display just like hers, but his hand moved slowly, fingers gliding over the smooth flesh, pressing lightly then relaxing, as if feeling the texture for the first time. His face grew redder, his breathing quick, and the bulge under his athletic shorts was now clearly visible, straining against the fabric. He didn't speak, and neither did she. The street continued around them, people passing by, some smiling, others quickly looking away, but the two of them were in their own private world, in a moment of silence filled with tension and forbidden warmth.
After a minute or two, Sophia gently pulled his hand away—not forcefully, but softly—and turned her head toward him. She gave him a soft smile, her blue eyes sparkling with a hint of mischief.
"Do you like what's inside?" she asked calmly, as if she were only talking about the clothes.
Yasser swallowed hard, unable to answer, but the hand that was still warm from touching her reached out and took hers again, gripping it a little tighter this time.
"Come on… let's go in and find something that suits you," she said, stepping into the store, her ass swaying with every step while Yasser followed behind, his eyes unable to leave the view.
That day was going to be more than just shopping… it was going to be a test of boundaries. And Sophia knew she was the one who would decide where those boundaries lay.
