Sure, it was very hard for the dude to sell his girlfriend but he knew it was the only way out.
After all, it was his fault they lost all their cash and he had to talk his girlfriend into placing her tight slit at sponsor's disposal. That day, they spent a lot of time discussing the situation and in the end came to the conclusion that it was the only option. So the dude found a sponsor who agreed to pay a good sum of money for a one-night-stand.
In exchange for that reward the lad tried out every hole of the petite and stunning cutie.
