Inviting only your closest friend, it might be safe for a while to avoid getting cummed on. Maybe you can "train" your life, to happen at least close friends around you, without getting them cum. If anyone plays along, it should be possible right? Not even close! As soon as you blow out the candles, a firecreacker blows up, releasing a fair amount of Semen straight into your face. Turns out no one knows who is responsible for this. It happened like "magic". Still, your cumming surpise delighted the guests.
After your initiate disappointment, especially when your friends you hoped would turn out to be a relief from the curse at least for a while, you cope with the embarrasing situation and have a good time.
