Squirting on FaceTime

Soooo to make this a long story short me and my dude that I have sex with on the regular decided to do something different since he is out of town for work which leads me to phone sex or I guess you can say FaceTime sex. So we are on FaceTime and I get my handy dildo and get to work so he can see. I always shake when I’m about to cum so This time I thought nothing of it. Out of no freaking where I started squirting it felt so good I didn’t know if I should stop or keep going. I ended up stopping it turned him on cause he never seen me do that it shocked me cause I definitely wasn’t expecting that. Anyways I always thought I couldn’t do that but I ended up doing it and now I feel invincible kinda lol does anyone know if it’s a trigger to start squirting or does it just happen random?
