Humiliation

Saturday i went to the adult bookstore to get some humiliation and pain.
I went into a video booth and lowered my pants and my briefs and left the door unlocked, even a little open.
I started masturbating.
After a few minutes a friendly face appeared in the door opening, he said i must really like bdsm, because he had seen me watch bdsm-movies there more often.
He must have thought was a sadist but i am not, i am a slave.
I told him i love the submissive side and he came into my video booth.
He pulled up my t-shirt and started pinching my nipples very hard. I liked it and moaned toe let hin know not to stop.
He left the door of the booth open so everyone could see me standing there with my pants on the floor and him torturing my nipples.
My little cock was hard as a rock.
He put his thumb in my mouth and forced it to the back of my throat. Normally i gag very easily, but now i tried to prevent the gagging and to take his thumb all the way in.
He called me "good boy" and that made me feel so good.....
Then he put two fingers in my mouth and repeated the process. Agina i took it all and he called me "good boy". It made my cock even harder.
