Stepmom brings home two hot young girls and makes me cum on my face in front of them

Pat walked in with two fucking hot girls in their early twenties. I was close to cumming already and them walking in started to send me over the edge. Pat ordered me not to cum so I stopped stroking to keep from cumming, then she ordered me to keep stroking, hard and fast. As they sat and talked about what a loser I was sitting there beating off, I was barely able to hold back. Pat gets a kick out of making me admit how turned on I am by the girls, I have to tell them what I like most about them. Then I have to talk about which one I like more, and why, as they sat and laughed at me, i was so ashamed. Finally Pat said she wanted me to cum, but I had to cum on my face, i was fucking humiliated as I put my lags up so my cock pointed right at my face and shot my load all of my face. When I sat up cum dripped off my chin, at least I was allowed to get a towel and wipe my face off..
