What can I say? I don't know much English. Google xD I had in mind the usual sex position, the code is fucked from behind, well, you can say 69 pose, if you remember that the husband is lying on the bottom.
You could say that.
And the case of no one knows the game in which the husband is right next to his wife during sex with another guy? For example, the pose in which the husband lies, and the wife in a pose with cancer and the men can see how she is fucked in the pussy.
I mean the presence of a penis cage in the novel.
And all this in the genre of treason. Still would not refuse from novels in which the wife or girlfriend of a guy changes completely at will without control, and so on.
