Intruder tickle both tied girls.
Elvina and Xenia can show intruder that they love this games.
So he hugging them and ungag.
They explain that this is their favorite games and they have no anything against been tied. And even glad that he helps them to be both tied at one time. They even ask him to make their bondage more tight and do not gag them when he leaves - they would not scream but want to chat while struggling.
Soon both girls have their elbows and toes tied and left for struggle. Elvina and Xenia love this experience and hope that intruder will return someday and play with them again...
