Brother, sister and mother went crazy

Katie found out that her adopted daughter still doesn’t know how to wash her pussy (and this despite the fact that the mare has already turned 18!). She took her to the shower to show her what was what and got so carried away that she began to make her wet. And everything would have been fine, only my brother passed by the bathroom and became an involuntary witness to this fuckup... The women had to offer a threesome (otherwise, knowing the character of this pussy, he would simply hand them over to dad).
