At the upper floor there is a long corridor with many doors. You hear females voices behind any doors. From downstairs Kelly instructs you also in this phase.
KELLY: This time you have to beat many horny girls. They are very expert in the art of teasing and will work your cock so badly to force you to beg for stop. Your trip will end here.
YOU: I will.
KELLY: Impossible, the biggest difficulty of this challenge is the exchange of girls. When you meet only one girl you learn her torture method and can apply some defense actions. Here you haven't time to understand.
YOU: I don't care.
KELY: give up now and take the consolation prize. This is last offer.
YOU: After all my efforts to be here, i not give up.
