My mother-in-law gets in the shower with me, is she crazy or what?

My mother-in-law gets into my shower, is she crazy or what? Mrs. August Taylor is not crazy, what happens is that if she sees her daughter's boyfriend in the shower and that he is having a good handjob, she will not be less and she will get into it with him, to continue giving a handjob and end up having a good fuck between mother-in-law and son-in-law.
