Curiosity piqued, I tiptoe towards the bathroom, my heart pounding in anticipation. Through the slightly ajar door, I catch a glimpse of my tia, her body glistening as she leans against the wall, fingers buried deep within her folds. Her moans, barely a whisper, escape her lips as she pumps herself, her other hand squeezing her breast. She's oblivious to my presence, lost in her own world of pleasure.
