Alex moved from the shadow of the table and stepped into Lisa's shadow silently. His movements were so quiet that Lisa was unable to sense anything, even when Alex invaded her shadow.
Alex was enjoying a nice view while following Lisa around like a ghost. Lisa moved to open the door to the balcony after finding the bathroom empty. She was also welcomed by the emptiness of the balcony when she peeped from behind the door.
Alex decided to have seen enough at this point and decided to show himself, though he had to admit that her back view was nice to watch those pairs of fair and thick thighs that supported her firm butt, he soon got bored of staring at them through clothes. It would be more fun to see their natural appearances.
Alex canceled the spell and a tall black shadow rose from within Lisa's shadow. The black shadow was like a lingering black ghost, formless and unstable as it flickered like a tongue of fire in the night wind.
