Lost in the city: I fucked a total stranger to stay at his apartment!

I found a totally lost girl in the middle of the street in Buenos Aires, and helped her out a little because she had no battery in her phone and I invited her over to my place, of course, to charge it and be comfortable for a while until she solves the problem... but the real problem was her hotel reservation got cancelled in the last minute and she needed a place to stay that night... I guess I don't need to tell you the rest?
