Suirmer, you certainly have a way to put things.
Well, what woman wouldn't enjoy having some kind of power over a male. Yeah, she must really get her kick from that.
I do not like my actual nipple to be tickled, but even though my fiance knows this, she seems to take some sadistic pleasure in playing with them.
There are likely triggers that make her wanna man handle... ahem... I mean wo-man handle you.
One trigger is probably when you show weakness or when she thinks you are starting to get the upper hand when you tickle her.
Your girl has some domme in her it seems.
I agree with sole seeker. You got to get her to relax and calm down and even if you like to visciously tickle her, you may need to hold off on that. Try slow pleasurable tickles, even in erotic places. Women like full long body caresses to. From the arms, down their ribs, sides, hips, thighs etc.
Ya know it, I always say this, but check out my tickle tips sticky thread at the top in the tickling discussion area.
There are so great calming and pleasurable tips as well as many other gems. Everything I see here in this place has an answer in that thread. Check it out some time. There are bound to be some tips in there that may just make her content to let you do the ticklin more often.
