I decide to accompany my 18-year-old stepdaughter to her first casting... Porn? FFM bisexual threesome

My stepdaughter asked me to accompany her to her first casting as a model, but what I didn't know was that the interview was getting a little messy as I realized that it was a porn casting! The man who was interviewing her started to pull out his cock and she without measuring anything started to suck it, I was impressed with what I was seeing but at the same time I was being tempted to do even better by going into this interview myself. My pussy started to get wet and I didn't think about it anymore, I told them that I wanted to be part of the casting and that I was going to improve it by having a bisexual threesome ffm.
