In order for a friend not to tell that a brother fucks a sister, I had to do a ZHMJ with her

«The brother has been fucking his sister for years, but before he managed to hide it until her friend started visiting them. The girl pinned the special relationship of a couple of relatives and so that she would not miss their little sex for the whole neighborhood, they decided to introduce her to their sex. At first, she resisted, but after tasting the boy's delicious cock in her mouth and pussy, she realized why her sister could not tear herself away from him.»
