I never dared a two hours session
for 3 resons:
Firstly ,the financal argument for sure
Secondly ,if it get`s tough ,you `ll be quite finished after that,and maybe yet beg for mercy !
and finally ,if it gets "very sensual" , as some fellowmen quoted yet , you`ll have "shot your load " some time
before these two hours - to "reload" super fast within short time , I`may be a bit too old unfortunately -
-however if she`s really super hot ,who knows eventually ??!!
but for sure ,if you like adventures(and have cash ) - don`t hesitate and do it !
