The painting preserves her silhouette, she preserves my silhouette

Again, the richest lady in the city invited me to her mansion to paint her portrait. This time it wasn't simply face painting, she was stripping in front of me! I blushed and turned away, but reluctantly turned around and started looking at her body to draw. I tried to calm down and said coldly in a low voice

"Sit still while I draw."

My heart beats every time I look at her body, she's so beautiful! Damn it!
