Lady Yna in An endless night of brutal tickling and tease

Lady Yna has an interesting torment in store for Her poor spreadeagled slave. After more than three months in chastity he is offered a handjob if and only if he can stand the torment of Her tickling fingers. But there is a catch to this offer, for every moment of pleasure, for every minute of her stroking fingers on his abused dick he must stand a minute of harsh, brutal tickling, from the soles of his feet all the way to his sensitive armpits, again and again, until he is mindless with pleasure, or is it pain? The teasing is endless, the tickling is more so as She promises a whole night filled with this exquisite torment. And if his whimpers and struggles are a sign, he must be aware that She always keeps Her promises.
