The cameraman cannot add much that you do not already know or suspect. He has had sex with just about every actress Ping and Sing have, including Sing's wife and daughter, with the exception of Li Sheng. He lusted after her but Ping had kept her for himself, often fucking her in front of the cameraman for him to film private movies for Ping. Lan Bao had felt that Sing trusted him, but went behind his back to have sex with his wife, who took some seducing, and his daughter, who did not need much seducing at all. In effect, the man knows very little and is only a so so cameraman. He would very much like to film himself having sex with you. Apparently his favorite position is to bend the girl across a table and use a small whip on her and he is imagining you in that position.
Li Sheng does not answer you right away, but takes some time to consider her response. "It has been very eventful, Mistress. I would never have thought this was going to happen. I will do everything to not let you down."
