and I liked the option of solving family scandals - if your wife refused you - punish her, go and fuck her daughter, this young whore! =)
author, I hope the main plot will continue to advance ...
Of course, the alternative universe is also good, but we should not forget about the main plot.
although, in general, the experiment can be said to be a success - I'm already wondering what it will result in. will MC's daughter run away from home, will her friend continue to come to visit (that is, did Sarah herself like that her best friend's father forcibly turned her into his personal whore)?
and it is interesting how the MC will lead Sandra herself to obedience - with her the same trick as with her daughter and Sarah may not work, she is larger than her husband in body weight. and her character is not submissive (although, perhaps, there are some doubts here).
but we'll see, we'll see.
author, please do not drop the main plot for the sake of the "dark branch".
