I quite enjoy tickling a ticklish young woman's bottom. And today, what with all the yoga shorts and fitness girls - young, supple-but-taut, healthy, fit, trim little morsels - one can hardly escape certain notions when surveying the young womanfolk.
I found that having my bum cheeks well oiled and spider tickled is quite the torture. Also having the spot where the lower cheek meets the thigh will put me over the edge if a power toothbrush is used. Either one makes me cry from laughing so hard. But, the tickling that makes me lose my mind is my favorite.
