Stay on her! Fists and feet!

You kick her hard in the face, knocking her over onto her back. You sit down easily on her stomach, pinning her arms at her sides with your thighs, and start punching her in the face. Helene takes at least 15 punches before she stops struggling. You blacken her eyes, set her nose bleeding, and bust her lips before the ref decides she's seen enough and pulls you off Helene.

As the ref administers smelling salts, it slowly dawns you: You won! Helene stares up at you, fear in her eyes; you can do whatever you want with her now.
