Damn son, you just had a great situation fall into your lap.

Tell her rent is three blow jobs a week.

DO NOT BUY FOOD or any other thing that makes life comfortable, (or essential.) Eat out for the remaining time she is there.

This could be so much fun.

Get sadistic. Have the electricity turned off and the heat. Stay with friends while this is going on and only go over to collect the blow jobs.

Bring home a big black guy and tell her, "I'm giving this blow job to him whore." and walk out and leave them to settle it.

When she's finally starving to death, throw a party with the condition no one can bring any food, just booze....

Get back with me after this, then we can start getting mean....
