Stand Your Ground

You size him up - all the while distracted by the librarian. She hops off the cart and eyes you for the first time with real fascination. She doesn’t adjust her clothes, so you get an eyeful of her ample breasts. She pouts her lips out, wondering what you're going to do to the guy who's been having his way with her. She also eyes you up in a way that has you thinking she might fancy you as well...

You glance over, looking seriously at this guy now. He’s bigger than you… but not by a lot. He’s not invincible. He adjusts his clothes, then quickly closes the gap between you both. He stares at you for a millisecond, just enough indecision for you to make your move. Whatever you do, you know you’ll only get this one chance.

You could swing for his head, trying a knockout blow in one shot. It’s a bit riskier, but if you land the punch, he’s likely to go down instantly.

You could also take a swing at his gut, a moderately less risky option. He’ll probably recover from it quickly, but he might be so winded as to back down.
