Olivia loses a bet and agrees to be tickled by her  friend Samantha.    She is stripped naked and tied to the bed in spread-eagle pose so she cannot move.    The tickler turns it into a game to find the most tickling spot. She  starts at her knees, then belly, sides, rips, armpits and finally tits  and nipples.    The victim refuses to tell her where she is most ticklish, but turns out  her breasts are. This is where the tickler is focusing later on.
