Bet lost - now the SPERM is swallowed!

I had a bet with a good friend that my favorite team would win the game. I was so sure! Of all times, they're going to lose. Now I "have to" pay off my bet debts and suck his cock dry, including swallowing the whole load. He doesn't need to know that the whole thing isn't really a punishment for me. Bet debts are debts of honor. What would your stake have been?
