Reluctant mom - son and his friends

My son and his friends tell me about their photography project they are working on, they say they really need to take photos of me for the project. I am unsure, I am not a natural at this and would feel weird posing in front of them but I want to help them so I say yes. I post in different positions and they tell me to take off my clothes, I am nervous but understand it is for the project so I do so, I am left wearing a nude see-through bodystocking. My son goes upstairs to grab something and his friends make me do more seductive poses. They tell me to get on my knees and put on a blindfold, I reach out in front of me and feel two of their dicks! This is so wrong, we shouldn't be doing this, what would my son think if he walked in?! I suck their cocks talking about how wrong it is and then receive a big facial all over my blindfold. My son enters the room and sees his mom sucking off his friends, he gets his cock out and puts it in front of me. I have no idea that I am now sucking my son's cock! I take my blindfold off and I can't believe what is happening! My son cums all over my face and makes me pose for more photos. Contains mild c . n . c.
