Holy Sly Flame
Ciel is enjoying Rebecca's breast milk while Rebecca enjoys the sensation of her nipple being sucked by Ciel's mouth.
Unfortunately, their fun had to be interrupted by the sound of Derrick falling.
Spontaneously, they stared at the dining room door.
Ciel's mouth dropped open as she saw Derrick while Rebecca hastily pulled the straps of her dress up to cover her breasts.
Her son was already a big boy, there was no way she was showing him the sensitive parts of her body. That was reserved for her lover.
However, contrary to Ciel's expectations, Rebecca did not look shocked, embarrassed, or anything.
She just knitted her eyebrows calmly as she stood up and approached Derrick.
"What are you doing here?" she asked Derrick in a rather cold tone, like she wanted to scold him for interrupting her activities.
Derrick wanted to protest, but he was still scared. He also knew that Rebecca would get even angrier if he protested.
