Train bathroom fuck with ball gag and arms bound

During the long train ride he pulled me into the tiny bathroom, already gagged with the bright red ball and my arms strapped behind my back. His hand fisted my hair, pulling my head up as he drove his hard cock into my soaked pussy, using the motion of the train to fuck me deeper. I pushed my round ass back onto him, bound and helpless, feeling my nipples harden while I moaned around the gag. My body shook with every thrust because I was so needy for him to claim me right here in this cramped space.
