Mom caught her daughter sucking her brother's dick and decided to teach her how to do it right

The brother and sister were fooling around, playing tag. But suddenly, the sister wanted to suck her brother's dick behind their mother's back. She started running after him and trying to catch his dick so she could put it in her mouth. And finally, at lunch, she succeeded. She crawled under the table and began to greedily suck her brother's dick. Suddenly, their mother entered the kitchen and caught them. But she didn't make a scene and say that brother and sister shouldn't fuck. She decided to join in silently and have a family orgy.
