"Now I'm going to have some fun and bother my friend Ivonne" Betty takes a pen, and tickling her, here it is most vulnerable...At her small,bare feet are now a target.She is most ticklish under her arms, on her feet, and she seems to lose control when someone really tickles and does not stop.Betty is the one who decides when is the end.Ivonne does not know what hit her,unsuccessfully struggled and trying to escape.
