Hanging around the office after everyone else goes home for the day can result in a series of question marks appearing beside 'The Pit' (on page where you select where to go next- Records, sales, etc). When I clicked the link and went down there, I (MC) got RAPED in the ass until nearly dead by some serum-crazed slave girl the trainers down there are apparently using to help with their 'work'. I did not find this part at all enjoyable, but if it sounds fun to you, knock yourself out!
Thanks for the answer. I have also seen the scene in "The Pit" now.
