Lucy diddled herself idly, waiting in front off the park entrance. Her boyfriend was late again, ugh. She watched the passerby, expecting him any moment, until one of them - not him! - stopped by to watch her masturbate. She paused, and smiled at him. He produced a knife and raised his eyebrows. Lucy spotted her boyfriend in the distance.

"Perfect," she thought. "Maybe he'll treat his next girlfriend with more respect."

She nodded at the stranger, and he stepped up to her. The knife plunged into her pussy, and she gasped, grabbing at the stranger's arm steadying her. He drove the knife in again - Lucy's knees buckled - then, with her hanging off of him entirely, into her breasts. Lucy whimpered pitifully, but found the strength to straighten up again, just in time for the stranger's lips to meet her own. She moved her tongue in his mouth, pushing through the pain as best she could as the knife made messy work of her chest and stomach. Finally, the guy stepped away, and Lucy locked eyes with her boyfriend, approaching at a run.

"Finish me," she whispered.

The stranger obeyed and drove the knife in between her ribs, leaving Lucy dropping down to the ground for the last time, gasping in pain and arousal, petty satisfaction driving her to her last orgasm even as she was quickly bleeding out.

"Serves... you... right..." she whispered into nothingness, her eyes unable to see anymore, before jerking and going still for the last time.
