First experience of two Sheilas in BDSM

A BDSM movie with a chubby caucasian girl with dark straight hair. She get a ballgag to her mouth and her hands and legs get tied to the bed really tight. She is in doggy position and her tits are hanging down. Her blonde mistress arrives with a black leather whip, starts to play with her tits and talk dirty, then pull up her skirt and start to whip her ass and in the end she take off the ballgag from her mouth.
