Ava and Amy, two lesbians with a penchant for the extreme, come together for a brutal fisting session. Ava's strong hands work Amy's asshole, first fingering, then fisting, making it stretch and gape. Amy's pussy gushes with each thrust, squirting all over Ava's arm. The sight of Amy's prolapsing asshole is the cherry on top of this intense, taboo exploration of the human body's limits.
