Extend the Story - Add a Room

You can't give him the opportunity to to get any leverage - you've got the upper hand now, but Mike's bigger and stronger than you. You let this slip and he'll be sure to seize the initiative, and then you'll be in real trouble.

Rather than let him pull away from you, you instead work with his movements, causing him to overcompensate and hit the ground face first. Soon, you've got him right where you want him, him beneath you your knee in his back, your leverage over him enough that he's going to be hard pressed to break free.

Which means you can finally show him just who he's messing with - and make him regret not letting you tie him up willingly. That said, given his lack of cooperation thus far, you might want to take an extra precaution first.

Use your leverage, start tying Mike up. More fun, less safe.
