Sung Jin-Ah felt a forbidden thrill as her brother Sung Jin-Woo watched her intensely
He knew her secrets her deepest yearnings 
Her eyes met his a silent promise passing between them 
The air grew thick with anticipation as she imagined their touch 
Soon their bodies would intertwine their desires unleashed 
Her breath hitched as he approached the moment they both craved 
His hands traced her curves leaving a trail of fire 
Every touch ignited a flame a burning passion 
Their lips met a desperate kiss sealing their fate 
Lost in their ecstasy they explored forbidden depths 
Pleasure surged through them a symphony of moans 
The night unfolded into a haze of pure bliss 
Afterward lying entwined a satisfied sigh escaped her lips 
Every nerve tingled with the memory of their union 
She closed her eyes dreaming of more forbidden encounters 
Her desires unleashed her spirit free in his embrace 
A secret shared a bond forged in the fires of passion 
She knew this was just the beginning of their journey 
Her heart pounded with excitement for what was to come 
Their love a secret flame burning brightly in the shadows
