Happened to me as well. Massage was going well. Masseuse became rock hard while rubbing my butt. I must have moaned or grinded my hips a bit which made him think I wanted him to go further. I did but not the way he wanted to. He put on a condom and flipped me over spreand my legs and tried to stick his cock in my ass. He was huge and it made me nervous. I told him no. I think it annoyed him a bit.
