Intro. Marcus is your 24 year old work colleague. He often goes to sport and is well trained. His girlfriend left him when he told her that he had a masochistic tendency. She did not understand the pain and humiliation to excite him and called him abnormally. You have been working together for a long time and you will find out that he is not doing well. He knows that you are gay and you like to try new things. He is not averse to living his imagination with you.

Marcus
