Arkain can feel that they are a little worried about what he was going to do. "Don't worry my friends. I have done this many many times before. I am much stronger than I may appear. Neither one of you are in any danger. I promise. OK?" He rubs his tail again. " Now just relax I am going  to let the air out of my tail and you will both get very tired and fall asleep. Then the next thing you know you be awake together in each others loving arms. Here we go." Arkain rubs his tail and opens his tail maw and the air lightly hisses out.. The air inside gets much thinner. The tail muscles drop down lower about you  starting to cover you like a big soft blanket.
