there is something so twisted about this couple. that is more than a fantasy, that is an illness and psychopathic behavior. like some folks also mentioned, in this type of situation irl, would end with one or both of them dead, the seme in jail and the uke dead, or the least likely the uke getting the heck out of the relationship. the relationship is tragic from beginning to end.
