Revy has been captured and compromised by guards, with a pistol pointed to her head she has not much choice then to obey their command. After violently pulling her pants down and stripping her from her boots and socks to expose her bare feet, they pressed her to the floor to let one of the guard dogs have its way with her. Even though being humiliated and hurt like that, the dog filling her asshole with its slippery knot and hot dog seed made her really wet and lusting for more.
