I'm not sure if this crosses the boundary or is just borderline. Specifically:
It might have been Rick's final answer, but this clearly wasn't the right answer, for the 18-year-old criminal had thrown Rick's axe away, forced Rick to lie on his front, and began to give Rick a taste of his own medicine. Rick's bottom was penetrated violently. Semen went everywhere. The remaining criminals, policemen, and security guards had now caught up and had dived on the pair of them. Semen sploshed all over everyone else, as an axe was wielded by a security guard, narrowly dodged by the 18-year-old, but this caused him to stop raping Rick, giving Rick an opportunity to escape.
