There was no point in hiding from my mother, I should have just invited her

The day the brother and sister realized that they didn’t mind having sex with each other, they began to have sex for hours on end, over and over again. There was only a small problem - it was mom's day off. That’s why I had to constantly hide from her while she was doing the cleaning, walking around the house. And so, when my sister was having sex in the shower, mom finally caught them! But there was no need to worry. The mature chick didn’t make a scene. But she just undressed and decided to give them a couple of sexual lessons, joining the third!
