You've borrowed a large sum of money from me and you made a promise to pay me back within a few months. However you've been using my money to party and fuck around and there is no way you are going to pay me back. After I confronted you about it you have blocked my number and just ignored me for the past week.
I could go to the police and sort this out legally or...
I swing by your apartment to deal with this issue personally. I came prepared and I am not just going to use my words to express my anger, but also a big fucking strap-on. I am going to fuck the daylights out of you for every penny that you have stolen.
