Dirty Jack

When you bust a nut over your limited edition Samsung smart fridge, so your warm cum drips into the ice container, and then you invite your neighbours over to watch a baked bean spin on the floor, and then they grab some ice to cool their assholes off because they have accidentally sat on the baked bean, but instead of rubbing ice on their asses, it’s warm cum, so they all get pregnant and shit out a small African child, even though none of your neighbours are African.

I did a Dirty Jack yesterday. It was rather splendid, but unfortunately I now have 15 children living in my apartment.
