It all depends on how I want her to react at first. If I want OMG I can't handle this immediately, I go right after her nipples. Off the charts ticklish. Or I could tickle her feet for as long as I feel like tickling them because she can take that, enjoys it. She has several spots that just drive her nuts right away, Nipples, Inner thighs, and her sides along her waistline. However, after she has an orgasm I can pretty much touch just about any usual tickle spot and driver her out of her mind. She is ULTRA TICKLISH at that point and really cannot stand being tickled. Sucks for her <weg>
