Quick splash - alarm during user rotation

I was invited to Berlin at short notice for a photoshoot and the studio was so cool that I was even allowed to film there in the evening. I wasn't sure if anyone would be available for me at short notice, but surprisingly a user with whom I had already planned something for later spontaneously agreed. We had already met for a coffee beforehand, so we got down to business very quickly. I waited for him on a sofa and when he arrived, I slowly undressed for him before calling him to me. Then I took off his trousers and started to blowjob his cock. He was still able to do that, but when I turned round so that he could fuck me doggystyle, he just came in less than 2 minutes. In return he sprayed a nice big load of cum on my face.
