Help! Tied up and used anal by the user - Part 1

I was looking forward to a normal user meeting, but it turned out very differently! He tied me up and gagged me so I couldn't defend myself.I was totally at his mercy and he really took advantage of my body! First he fingered my pussy and then he just put his dirty cock in it. When he was done, I tampered with my sweet bottom. It was really hard, but it also turned me really on that I couldn't do anything and he just used me for his desire!
