For me, it looks as if the foursome has changed the relationship thoroughly. Unfortunately, we do not know what now is the relationship between Masha and Topknot. For Sahsa it must be very frustrating when he fucks Masha and she thinks of the cock of the other man.
This foursome has obviously also changed the relationship of the other couple. At least it seems as if the black-haired girl also had some problems, after she has seen how her lover so intensely fucked Masha. Let us hope that everything turns to the good.
