In the dimly lit bedroom, the sister tiptoes in, her eyes locked onto her brother's sleeping form. His toned body is totally exposed, the sheets kicked off in the heat of the night. She can't resist the temptation, her lust for him growing with each silent moment. She climbs onto the bed, straddling his hips, feeling his cock already semi-hard against her wet panties. Slowly, she grinds against him, his cock growing harder with each movement. She reaches down, guiding his throbbing member into her eager pussy, and begins to ride him, her moans barely contained as she fucks him in his sleep. -
