A maneuver...

The beast's massive cock continues to slide across her cum-slick armor and dribble streams of the warm yellow fluid on her cheeks and hair. Marie realizes that she's almost lost, but the engineer is not willing to surrender without a fight. While her condition is dire, she recognizes that the monster above her is still wounded, trapped, and ****.

By luck or sheer stubbornness, Marie had managed to hold on to the surgical blade as she was dragged across the floor. Gathering her remaining strength, she brings the blade up and slices down into the side of the beast's huge cock, releasing a stream of yellow ichor. The monster rears back with a roar of shock and pain, releasing Marie's leg.

Seizing her opportunity, Marie rolls to her left, quickly pushes herself up to her hands and knees and darts forward, away from the nightmarish beast. Pursued by the furious roar of the trapped creature, Marie runs toward the open tram doors.
