While she does get anally fisted in other gangbang scenes, these 40 scenes focus on anal fisting/toy play with Rebel+various girls and Giorgio Grandi. There is not any MF sex involved. There is lesbian play in the scenes with other porn actresses. I've collected these scenes from various sources and also purchased around 16 that I was missing from xvideos.
I think Rebel is currently the best anal performer in the biz(and one of the best ever) and these scenes help showoff her amazing talent, especially the ones with Giorgio as he gives her some hard fisting that Rebel absolutely loves.
