Controlling my urges

Description: I have always struggled to control my insatiable need for pleasure.  it is now time for some serious punishment for help me, and you have set quite a difficult (and painful!) one for me.  i must slap my pussy with increasingly hard implements in order to deter my needs.  i start with my hand, before moving onto a leather strap and finally a wooden bath brush.  ouch!  unfortunately, rather than quell my urges, this only turns me on so i end up giving myself an orgasm with my vibrator, making my white cotton knickers soaking wet in the process.  you think a touch of humiliation might help me so you have me on all fours with my knickers in my mouth to think about my behaviour...
