Mmm. That's getting me hot, but it seems that you're not quite there yet. Stroke as fast as you need to in order to get as hard as you can. If you cum you're going to get your wish about hot sauce up the ass. Instead of seven drops though, you're going to put fifteen and finger fuck your ass until the burning stops.
When you're as hard as you're going to get, pull out one of your shoelaces and wrap it around your cock and balls. Make sure it's tight. I don't want you getting soft during this. Make sure your veins are popping out!
