My private teacher learned me the meaning of blowjob in germ

I was studying german and was surprised about the word blowjob. I asked my private teacher and he told me that it is not german, he told me that the word blowjob is english and it means cock sucking. I teached me that without any word. His hard cock in my mouth helped me to understand all. And now I know also the meaning of the word facial. Because he shot a big load of cum in face. A cum covered face after a blowjob is a facial. And this private teacher gave me a very, very big facial after the blowjob.
